If your ts is on a udp source use that as an input to ffmpeg

Hi

Thanks for your reply.

Just an example of a server of Quad core 3.0 GHZ 8MB cache and 8MB Ram on
ubuntu box.
How many channels do you expect it can work fine?

This will be completely dependent on your hardware in use. A low spec
machine might do 1 decent quality and a high spec would do many

0x40 should work for AAC.

You're trying to create a shared library while linking against static
library. Compiling only ffmpeg libraries statically will solve the problem.
Or if you really want to build shared ffmpeg libraries, install the shared
libraries of the dependencies.

With regard to the question, "How many FTA channels can be transcoded?", a
previous responder said it depended on the hardware.

This is true, but it also depends on the source material, eg, SD or HD, and
what you would like to do while transcoding.

Your best approach is to start compress some video that is similar to your
source material and see what the performance is.

3 seconds in the -hls_time setting is an unusual value, Apple recommend 10
though lower values generally work OK.

Note that for this to really work effectively you need to force key frames
to occur at the boundary of every segment otherwise you will find that the
segmenter will need to choose a segment size that matches where the key
frame is.

You should also look at the -segment muxer for a more complete list of
options where m3u8 is the HLS format.

If you are asking about webcam, SDL can't help you.

If you mean webcam, and using the ffmpeg command line utility, take a look
at the wiki:

Thanks very much, is there any c code I can reference? if I want to use
ffmpeg utility, how can I use it? our idea is get surface of direct or
opengl to get the picture at start. but we don't have any experience on
them, so we want to ask if ffmpeg can implement it, thanks.

not webcam, thanks for your help

No idea, ask on a PHP list.

why the hell do you start another thread for the same
problem when you clearly got explained that this is NOT
ffmpeg related at all?

ask you hoster, ask your serveradmin, ask yourself why
you want broken by design actions like shell_exec()
froma webserver process instead call PHP as CLI

however: THIS IS NOT FFMPEG RELATED

Hello,

While using ffmpeg with shell_exce , as soon as command run , browser
redirect to 500 Internal Server Error instead of page that is given.

Is there any settings required in ffmpeg configurations ?

lets follow the rule...
can you provide complete, uncut console output of the command? afaik,
shell_exec should return string outputed from executed command. and also
provide your command.

shell_exec() = PHP

if it does not work -> PHP problem, not ffmpeg

maybe the hoster recognized that shell_exec() was not disabled
on the unix machine as you said in your yesterdays thread and
now he fixed the server configuration, stop to insist in calling
shell commmands from web-server processes, this is a broken idea
and only possible if the server-admin was an idiot

a 500 error after a php command is as i explained you yesterday
a FTAL ERROR on the php-side and you need to CONTACT YOUR SERVER
ADMIN and even if it would be a problem with the ffmpeg-command
you refused to post the command, but as said: unlikely

> Is there any settings required in ffmpeg configurations

there are no "ffmpeg configurations", you have a commandline with params

shell_exec() returns NOTHING in case of a "500 Internal Server Error"
because it leaded to a FATAL ERROR on php-side most likely by a sane
setup which was fixed by the admin

Message-ID: <CAEnqZEV=gyZV7Bj60K67vYvMtYwGkzXJ_r7cFrAiSdK8Vmx=9Q@mail.gmail.com>

Hi,

I am trying to build ffmpeg with vid.stab support. I installed vid.stab
from git head and then configured ffmpeg from current head with

./configure --enable-gpl --enable-libvidstab

That failed with "ERROR: vidstab not found" although headers and lib are
installed in /usr/local/include and /usr/local/lib. This seems strange
because the header file and function that are used to check availability of
the lib are there AFAICS and permissions seem correct as well.

Has anyone else experienced similar problems or build instructions for
getting vid.stab to run with ffmpeg on OS X mountain lion?

Thanks,

Robert

Plug card in, scan for channels, tune it to a channel, give the data to ffmpeg.

If you are using linux, you can use the utilities w_scan and szap to
scan for channels and tune the (satellite) adapter respectively.
Having done that, you can access the MPEG-TS of the tuned channel by
reading from /dev/dvb/adapterN/dvr0. Google has plentiful instructions
on how to use w_scan/szap.

Cheers

Sorry for the false alarm. It seems to be a bug in the python wrapper. 
ffmpeg generates all frames if I extract frames into an image sequence.

desire pkg-config for finding libvidstab. This may or may not be unlike
with other libraries.

So please check whether
a) you have /usr/local/lib/pkgconfig/libvidstab.pc, and
b) pkg-config by default also searches /usr/local/lib/pkgconfig .

If b) does not apply, you might want to set the environment variable
PKG_CONFIG_PATH to point to /usr/local/lib/pkgconfig .

Oh, another thought: Does ffmpeg search /usr/local? But as I mentioned,
vid.stab support seems to require pkg-config.

Just guessing,
Moritz

and guessing well :-). That was it. The pc file wasn't in
/usr/local/lib/pkgconfig and after creating the directory and manually
adding it, configure and compile went through without problems.

Thanks a lot!

It sounds like you want to feed a stream to FFmpeg, transcode it to .mp4
and save it to file.
If that is possible it should not be to hard.
You need to know, location of the stream, like http://radiox.com:80
You need to know destination bitrate for audio and video
Is the source Interlaced or progressive
What is the video codec youy want to use.
And why do you want to transcode it to .mp4?
A lot of mediaplayers can handle transportstreams (.ts)
and also a lot of software video editors

I feel your pain.

ffmpeg is a lovely program, but underdocumented and underdocumented.  But I
repeat myself.

Command line options to ffmpeg are context dependent.  How many programs
are in the transport stream?

Your best bet would be to search on line for examples of ffmpeg usage and
try them.  It will be an iterative process.

It's ts coming from ota. It will be converted and saved to mp4 unless it 
can be converted and streamed directly without saving.  I imagine though 
it will have to be converted to mp4 and saved.  Would like to be able to 
stream the mp4 file as the ts is being converted, with a delay I know.

Hi Paul,

I see you are submitting patches for that now. Please let me know when I can pull the repository version to test that.

In the meantime, and this all goes for the OpenEXR encoder, I've setup a standalone program to do some analysis on the YUV resampled data before I can check the channel-splitter filter.

And I have a problem that I've been blocked on for a while.

You can see the code on Github here: https://github.com/up4/fauxraw/blob/master/fauxraw.cpp

The faulty code compiles fine, but gives a "Segmentation fault (core dumped)" on execution. When I remove the resampling context allocation line ("swsCtx = sws_getContext?") the segmentation fault is gone too. The resampling I'm looking for is 422 10-bit to 444 16-bit for exact picture size. Is it possible? Is there something wrong with my "sws_getContext" call?

Thanks,

Vincent

Hello,
I use ffmpeg to stream video with rtp protocol, i use crop and overlay filter.

but i want to modify cropping parameters during runtime and change the overlay filter to another movies or png.
I searched in ffmepg.c but I have difficulty to modify it to have dynamic crop and overlay.
How do I do this?
Can you help me, please?

Thanks a lot for the explanation.

I tried demuxing the video stream from an FLV file, but it didn't
work:

[C:\]ffmpeg.exe -i input.flv -c:v copy -an output.m4v

The problem is there's a lot of tutorials out there that are
apparently outdated, and it's not obvious to newbies to tell.

I was able to load the AAC file in Audacity directly, without having
to put in a container.

I needed to split and invert the L/R channels before building a new
audio track to get rid of some music.

Thanks for the help.

Of course, but allow me to say how difficult it is for 
us to understand why you are searching for third-
party tutorials when there is example code in the source.

I believe this is possible with FFmpeg.
(But I may misunderstand the word "invert".)

You cannot mux Sorenson Flash ("flv1") into a iDevice 
file ("m4v"), your iPhone / iPad would not play the 
resulting file.
You should also not mux Sorenson Flash into mov, it 
is not defined afaik.

Because I didn't understand the source and found other articles
contained examples that I could use right away.

But I'll first read this the next time
www.ffmpeg.org/documentation.html

Good to know. I'll give a try if I find another file that has the same
issue.

Which container should I use to demux a H264 video stream from an FLV
file before editing it with eg. AviDemux or Sony Vegas?

H264 goes in to many kinds of containers (mp4/mkv/ts/mov + more), but
you don't have H264, you have flv1 - or at least, the file you were
trying to use does not use H264, it uses flv1.

My mistake. So I justed the same container to hold just the video
stream. VLC now does show the correct length and I could edit the file
in AviDemux.

Thanks all for the infos.

Have you checked what actual values you pass to it? Because it looks
like its segv inside swscaler.

Subject: [FFmpeg-user] Audio freezes when concat videos
Message-ID: <CACguf=9s4s5V8gM3SyTOvK9oGiJ6-5SJdbOB7jom5OQrysqWfQ@mail.gmail.com>

Hi, I have some video chunks (file1.mov file2.mov... - h264/aac) that come
from a source that I have to stream continuously. My problem is that I have
a little gap between each chunk that I stream. This is particularly
annoying for audio...

I first set up a 'server' with this command :
ffmpeg -i udp://localhost:5555 -f flv rtmp://localhost/live/stream

then I can add each chunk with :
ffmpeg -i fileXX.mov -vbsf h264_mp4toannexb -f mpegts udp://localhost:5555

Any suggestion to fill the gap or having smoother transitions ?

Best regards

Message-ID: <CAC_TPCKCoUXd=nDnJg7f00wBKaoHcLS1c6UY=Qm8kPDQi02C7A@mail.gmail.com>

Hey guys,
I'm trying to build on Windows under Cygwin, and I'm finding that ffmpeg
and ffprobe are working fine, but ffserver isn't being built. (Also ffplay
isn't built, but I don't care so much about that.) Below is how I've
configured the build - can anyone see anything I've done wrong? I can't
seem to find anything in the configure script that would cause it not to
build ffserver.

Thanks for the help!

Subject: [FFmpeg-user] FW: FFMPEG Custom Read function reads all the data

Hi,
I'm trying to implement a custom read function for ffmpeg that will retrieve a buffer from local video ( from device in the future) and then deocde this buffer, etc..

So, here's my read function 

    int IORead(void *opaque, uint8_t *buf, int buf_size)
    {
    FileReader* datrec = (FileReader*)opaque;
    int ret = datrec->Read(buf, buf_size);
    return ret;
    }

As for the FileReader :

     class FileReader { 
     protected:
      int fd;
     public:
      FileReader(const char *filename){ //, int buf_size){
          fd = open(filename, O_RDONLY);
          };

     ~FileReader() {
           close(fd);
         };

     int Read(uint8_t *buf, int buf_size){
       int len = read(fd, buf, buf_size);
       return len;
          };
     };

and for the my execution :

    FileReader *receiver = new FileReader("/sdcard/clip.ts");

    AVFormatContext *avFormatContextPtr = NULL;
    this->iobuffer = (unsigned char*) av_malloc(4096 + FF_INPUT_BUFFER_PADDING_SIZE);
    avFormatContextPtr = avformat_alloc_context();
    avFormatContextPtr->pb = avio_alloc_context(this->iobuffer, 4096, 0, receiver, IORead, NULL, NULL);
    avFormatContextPtr->pb->seekable    = 0;

    int err = avformat_open_input(&avFormatContextPtr, "", NULL, NULL) ;
    if( err != 0)
     {...}
    // Decoding process
      {...}

However, once the `avformat_open_input()` is called, the read function `IORead` is called and keeps reading the file `clip.ts` until it reaches its end and only then it exit and the decoding process is reached with no data to decode ( as all of it was consumed)

I don't know what is the problem especially that this code 
     AVFormatContext *avFormatContextPtr = NULL;
     int err = avformat_open_input(&avFormatContextPtr, "/sdcard/clip.ts", NULL, NULL) ;
isn't blocking untill the end of the file is reached. 

Am I missing something ?
I really appreciate your help.

Anders - will this be similar to tsMuxeR or tsReMuxer and possibly work on
AVCHD MTS files?

What does "grep FFSERVER config.h" show?
(If cygwin is really missing "fork()", you 
will have to switch to mingw.)

The next time you had an configure error, try to look at config.log. Most
time it will give you a error message.

Hi,

I was trying to process a video file using ffmpeg. It is not processing. I am pasting the command line output of it. Would you please help me to sort this out?

Thanks a lot,

The error message you posted was the output from configure. What
Timothy was explaining was that in the file config.log it will contain
more details about why vidstab was not found, not just that it was not
found.

The way configure works is that it will try to compile lots of small
programs to see if the expected API is there, and to work out what
libraries it needs to link to. If a library changes its API, the small
program will not compile, which is the same result as if the library
was not found. The output of trying to compile the small program is
stored in config.log, and seeing the output helps determine why the
library was not found.

Cheers

Subject: [FFmpeg-user] AAC conversion from 7.1 channel to 2 channel
Message-ID: <CAPJ_JDzp4usxnFzdfVCxkm1acw0O=rNPed=qzX0xiJ5rm81Teg@mail.gmail.com>

Hi,

For AAC conversion from 5.1 channels to 2 channels, ffmpeg code uses
surround_to_stereo() in libavcodec/Resample.c

In that the input data was packed in the format fl, fr, c, lfe, rl, rr
        fl = input[0];  // front left
        fr = input[1];  // front right
        c = input[2];   // center
        lfe = input[3]; // low frequency effects
        rl = input[4];  // rear left
        rr = input[5];  // rear right


I would like to convert AAC 7.1 channels to 2 channels.
But i have no idea about how the input data is packed.
Can anyone please tell me how the input data format is arranged for AAC 7.1
channels ?

Regards,
Rohit

This looks outdated, I believe you should use 
libswresample.

Did you try?
Without testing, I suspect it should work.

FFmpeg internally expects wav channel order.

> is arranged for AAC 7.1 channels ?

In aac, different channel orderings are possible, 
and usually it is not wav-order, but the aac 
decoder should correctly order the channels.
(If it does not, this would be a bug, reports 
are very welcome!)

Subject: ffmpeg 1.0.5 and buffer underflow
 


I've been using ffmpeg for several years to encode video into DVD format.? Mostly old home movies to hand out to the rest of the family.? Lately, I've been getting hammered with buffer underflow errors, even with video I've encoded successfully.? I'm using Fedora 18 and ffmpeg 1.0.5.? I've googled this problem, but found only posts that are ~1 year old or more and have tried a few things to no avail.? Anyone got ideas on how to fix this?


----

I have some additional info on this issue that I hope will help find an answer to this.? It appears that I get the buffer underflow when I am encoding HD video to NTSC DVD format.? The only way I can keep that from happening is to set the video buffer (-v:b) to 0k.? The only problem is the video is so blocky as to be nearly useless. Anyone else having this problem?? Ideas on fixing it?

You could search config.log to find the missing 
dependency, search for "check_func fork".

Definitely onto something there. Couldn't resolve the reference to _fork().

check_func fork
check_ld cc
check_cc
BEGIN /tmp/ffconf.Rv3Ey5Ns.c
    1   extern int fork();
    2   int main(void){ fork(); }

/tmp/ffconf.UGHkK6sH.o:ffconf.Rv3Ey5Ns.c:(.text+0xc): undefined reference

collect2: ld returned 1 exit status

I know Cygwin has fork(), though - their FAQ even explains how it's
implemented - and checking the objdump of /usr/lib/libc.a, I think,
confirms it:

$ /usr/i686-w64-mingw32/bin/objdump.exe -t libc.a | grep fork
[  4](sec  1)(fl 0x00)(ty   0)(scl   2) (nx 0) 0x00000000 __fork
[  5](sec  0)(fl 0x00)(ty   0)(scl   2) (nx 0) 0x00000000 __imp___fork
[  4](sec  1)(fl 0x00)(ty   0)(scl   2) (nx 0) 0x00000000 __vfork
[  5](sec  0)(fl 0x00)(ty   0)(scl   2) (nx 0) 0x00000000 __imp___vfork
[  4](sec  1)(fl 0x00)(ty   0)(scl   2) (nx 0) 0x00000000 _dlfork
[  5](sec  0)(fl 0x00)(ty   0)(scl   2) (nx 0) 0x00000000 __imp__dlfork
[  4](sec  1)(fl 0x00)(ty   0)(scl   2) (nx 0) 0x00000000 _fork
[  5](sec  0)(fl 0x00)(ty   0)(scl   2) (nx 0) 0x00000000 __imp__fork
[  4](sec  1)(fl 0x00)(ty   0)(scl   2) (nx 0) 0x00000000 _vfork
[  5](sec  0)(fl 0x00)(ty   0)(scl   2) (nx 0) 0x00000000 __imp__vfork

There are some other failing checks and missing libraries (for example,
anything with -lrt fails, check_func fcntl fails) that lead me to believe
there's something wrong with my environment - it doesn't seem to be
searching /usr/lib for libraries to link against. But I'm rather a novice
at this, so maybe I'm wrong.

----------

I'd really hoped to avoid that mainly because it's a very simple command line, there's nothing odd about the files I'm encoding or what I'm encoding them into.? However, I've attached the output of the encoding process on the exact same file with the basic command line and then adjusting the video buffer to 0k.? The file itself isn't anything special:

[markh at augustus Season 1]$ file Vacation2011.avi 
Vacation2011.avi: RIFF (little-endian) data, AVI, 720 x 404, 23.98 fps, video: XviD, audio: MPEG-1 Layer 3 (stereo, 44100 Hz)

At first I thought it was a heat issue, we'd recently moved and I was worried that the airflow may have been flaky.? I had noticed errors with BOINC and seti at home so did a thorough cleaning of the my big system as well as making sure CPU temp stayed stable.? This box generates a lot of heat being a dual Quad-core system.? 

I hope this helps.? I've encoded this file cleanly before with the exact same command line on this system, the HW and OS (Fedora 18) have stayed the same the only difference that I can find is ffmpeg was upgraded to 1.0.5 when encoding started bombing.

Dear Carl,

Thank you for your message. It works with newer versions. However the output I get has blank frames. I did?ffmpeg -i input.avi ouput.avi. Since I didnt give any specifications it should have just converted by taking all the specifications of the input file. Doesn't it do that? Do I need to specify the codec also? How do I find the right one? Could you please help me with this? I tried attaching the input and output videos, but the email didn't go through.

Thanks a lot,
sumesh

Unrelated:
There are two possibilities: Either these options are 
useful, then they should be made default for FFmpeg, 
this needs either a patch sent to ffmpeg-devel 
(together with the explanation why the patch is needed) 
or a bug report explaining why a particular option 
should be set.
Or the options are not useful, then you should remove 
them from compilation.

(Some of the options are not useful / harmful, for 
others I honestly don't know.)

have you ever considered to google them?

"-D_FORTIFY_SOURCE=2 -fstack-protector --param=ssp-buffer-size=4" are
default for ANY package of most linux-distributions since years for
security reasons

and for a hardening build you enable "-fPIC -fPIE -fstack-protector-all"
too as also "-Wl,-z,now -Wl,-z,relro" as LDFLAGS

yes, they affect performance, but security first

Do they affect compiler performance or also the performance of the final
build?

Do you know of any problems these parameters fix?
(Iirc, the exploit for Ubuntu "MPlayer" - which is 
not MPlayer - also worked with these flags, or am I 
wrong?)

None of these are used above, so I wonder how this 
is related?

And please note that of the options you did not comment on, 
some are useless, some harmful, so the argument "people 
know what they do" (in case this is your argument) 
seems insupportable.

the performance of the final build, how esle should this work
if there is code added, on i386 it hurts around 10% but on x86_64
at least the overhead of -fPIC -fPIE can be ignored

who cares about 10% performance in case of more security?
well, nobody said "make it default", but Carls attitude was
"why do you not remove it" which is plain wrong

hence if i have a server where users can upload videos which are
rpcoeeded in a cronjob i do not care about some % performance but
i do care if someone exploits my machine with bad input

maybe you should comment the one of one and not quote
the whole option line and say it is useless?

Subject: [FFmpeg-user] Convert PAL dvd with menus to NTSC dvd with menus
Message-ID: <20130504132819.GA763@verizon.net>



Hi,

I have a PAL dvd with menus that point to individual video fragments. I have seen other methods that convert everything out to the individual VOBS, but i was wanting to convert the entire dvd structure, with menus intact, from PAL to NTSC, to a VIDEO_TS format, suitable for burning to dvd, ideally. Is this possible with FFMEPG? Can someone suggest or point to the command(S) necessary?


Thanks for any help,



Russ

Only the binary performance is relevant.
(The compiler performance is of very minor relevance, 
and FFmpeg by default uses options that very badly 
affect compiler performance.)

I am not saying it is useless.

What I am trying to say is that the options look as if 
they were added by somebody who has no clue.
(Which - if my suspicion is correct - would make the 
security argument void.)

well, and that is why the options are there
and that's my static build for servers with static libx264
on x86_64 there is no noticeable impact at performance
the same for PHP, APache, Postfix. Dovecot, MySQL.......

at least on i7-3770 and Xeon E5-2640

some of the performance penalties may be negated by the compiler-optimizing
for recent CPU's and agin: that is why the options are there and rpmbuild
exists to make predictable and deployable packages on test-machines

It should be noted here that a 1% speed issue 
is considered a severe issue in FFmpeg development.
(Or in other words: A 1% performance improvement is 
generally seen as a very valuable contribution.)

No objection here, but I should repeat that you 
should elaborate a bit on what kind of issues 
can be avoided by the options.

No, that is not my attitude, on the contrary:
If the relevant options fix some (theoretical) issues, 
they should be made default (with an option to disable 
them) or at least configurable.
If the options do not fix any (theoretical) issues 
though, they should indeed be removed.

In any case, options that are not understood 
should probably not be used.

I hope you are compiling your executables with 
increased assert-level set (this definitely fixed 
some security issues in the past).

I like Wikipedia but it is typically not relevant 
for technical discussions.

With an option to disable them in case they have a 
performance impact.

Yes, that was it. Stupid of me.

Now, it segfaults at "av_image_alloc". If I change this call to "false" it runs fine.

This time, I did what helped me fix the first problem. My code is 100% copied from the trunk's example.

If you know anything. Please, please, please let me know!

Also is the channel extraction filter ready for use? Can I pull it from the repository?

Regards,

Vincent

Hi,

For AAC conversion from 5.1 channels to 2 channels, the equation used in
 surround_to_stereo()  in libavodec/resample.c is

*        l = av_clip_int16(fl + (0.5 * rl) + (0.7 * c));*
*        r = av_clip_int16(fr + (0.5 * rr) + (0.7 * c));*

I was not able to find any algorithms/equations for converting 7.1 channel
to stereo.
Is there any equation for converting 7.1 channel to stereo ?

Regards,
Rohit

Dear all,

Since I didnt find any response to the previous question, so I am putting it again with some more details. Sorry if you have already seen it, but I cannot find a solution to this right now, and hoping somebody here might have ideas.

I have created a movie 'input.avi' (from matlab, in a mac machine). Then I did 'ffmpeg -i input.avi output.avi'. My idea is to reduce the size of the file, however right now I am not giving any options since I want to see by default what happens so that I can do it optimally. However the file output.avi produces a movie of same length but with completely black frames in it ! I do not see anything like this reported in a google search. Has anybody encountered such things ? How would I resolve this ? Can anybody hint ? By the way I am using ffmpeg for the first time, so may be I am doing something very stupid ? Here are details about the file:

Dear Carl,

Thank you for your message. It works with newer versions. However the output I get has blank frames. I did?ffmpeg -i input.avi ouput.avi. Since I didnt give any specifications it should have just converted by taking all the specifications of the input file. Doesn't it do that? Do I need to specify the codec also? How do I find the right one? Could you please help me with this? I tried attaching the input and output videos, but the email didn't go through.

Thanks a lot,
sumesh

This is old, if the problem is also reproducible 
with current FFmpeg, please provide the sample.

This version of ffmpeg is the default Fedora 18 rpm. I did nothing but install it. I've never had trouble encoding before so I didn't, and don't, see a need to mess with the binary.

Hello, sorry but I don't keep mails from this thread, so my "answer" could be
wrong...

If you are the guy who complained about buffer underflows (I don't have the
previous mails from this topic to verify), and if I well remember, you talked
about "no arg buffer" but didn't provide any command line ('cause it was a "so
simple command") but only some ininteresting outputs.

if I mistake, sorry for the noise.
if I well remembered, so buffer size is needed by the encoder to know how it has
to compress the current image. But you didn't provide any way to help you with
these non-informations... So take a look to help and add some buffer value
first.

bye
PS: and sorry if I confused (I didn't read again the entire thread)

This does not exist in current FFmpeg.

As said, channel downmix happens in libswresample.
If you have any problems with it (if it does not 
work or if it does not work the way you expect) 
please report it here on the mailing list.

A typical test could be the following:

It is not needed to "describe" the output file 
but to show the command line and console output 
that produced the failing file.

This is too old, please test current git head and 
report back.

Message-ID: <201305051325.49987.rhkramer@gmail.com>

A friend of mine wants to get some personal (but not that personal!) VHS tapes 
converted to DVD, and some audio (I think she said cassettes) to CD.

I just thought I'd ask here if anybody is interested in doing this (at a low 
price) or knows of a low priced service.

Thanks!

?Dear Lou,

Thanks a lot for the reply. The frames are black and blank in real player. In VLC it plays fine. But I wanted to put them in a presentation where compatibility with real player is needed.

I didnt know that its such an old version. After a struggle I have done this installation in my MAC. Wondering now what to do!
?Thanks,

sumesh

It segfaults in it or after using it? Perhaps you again set something wrong
as argument and never check function return value.

I have written my command-line 2 posts ago with hope that somebody might 
try it with a new version, because I am not a compiler-type. I get my 
ffmpeg-version from packman and if I get to know, that webm with Firefox 
works with a new version then I will mail this knowledge to Packman.

Except for creating VOBS, it seems need another tool to create DVD with
menus, for example, DVDStyler: http://dvdstyler.org/en/

Hi

I have a problem for FFMPEG comile with libopus. I alreay install libopus.

I had confugre by follow option.

/configure --enable-gpl --enable-version3 --enable-pthreads --enable-libopus

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user at ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.

Look the config.log file. Near the end of the file you will get the exact
reason.

The usual reason are either a missing -dev package (if using packages) or
the library installed in directories the compiler does not search by
default (if built from sources).

I seem to have compiled my ffmpeg with "--enable-libass"; yet, when I issue:

                        ffmpeg -i myvid.avi -vf ass=mysubs.ass output.avi

I get:

No such filter: 'ass'
Error opening filters!


What gives?

One thing I'm seeing is a warning in my ffmpeg config, about a mismatch.  Could
THAT be related to the problem?

Your problem is here: your ffmpeg binary is not using the shared libraries
you compiled at the same time, probably because the priorities of your
shared libraries are not correct. You can check it using:

ldd /path/to/ffmpeg

This is not a ffmpeg problem but a Unix administration problem.

In the future, please remember not to hijack threads; if you do not know
what it means, look it up. For this thread, of course, the harm is already
done.

Apologies. A bit sleep-deprived. I do know about the "hijacking" phenomenon, and
that it is to be avoided.  I guess I've had only a vague notion about how/which
email headers would formally create a threaded chain, and was "hoping" that
wouldn't happen just now.

I forgot to fill in the subject (intended it to be what this subject is)

(at least I didn't top-post!  -- got 1 out of 3, right? ;-)

I'll try "distclean", and report success or failure. Thanks to both responders.


Totally unintentional. My apologies.  And I do know about the "hijacking"
phenomenon, and that it is to be avoided.  I guess I've had only a vague notion
about how/which email headers would formally create a threaded chain....

I'm also a bit sleep deprived

What he did was:
$ ./configure --enable-shared && make
$ ./configure && make

It needs a "make distclean" between the two.

Yes, that seems to be right: I see now that there is no --enable-shared in
ffmpeg's banner while it is there in the libraries'.

OK, I'm making progress. "make distclean" and recompile made ffmpeg acknowledge
libass, but now I'm getting:

Could not create a libass track when reading file 'mysubs.ass'
[AVFilterGraph @ 0xad8d320] Error initializing filter 'ass' with args
'f=mysubs.ass'

I don't see any documentation for the syntax in man pages, will search around

Thanks for the quick help.

I didn't "break a thread" ? i tried to UNhijack one, and fill in the missing
subject, in compliance with the complaints.  But majority insisted to continue
the "hijacked", "no-subject" thread, so, I'm replying to that, to fall in line
with the majority.

Please do never post one line of the console output, 
always post your command line together with the 
complete, uncut console output.

 redhat linux while not being root?
Message-ID: <CA+xx23Tg2DNz6-RRyw3sbcaizX1+N7qz20B4JVxvss5hrfRd_g@mail.gmail.com>

I'm on a shared host that is running on Red Hat 4.4.7-3.

All these packages have successfully installed: - presetup.sh, autoconf.sh,
automake.sh, libtool.sh, libiconv.sh, libpng.sh, libjpeg.sh, zlib.sh,
libwmf.sh, freetype.sh, gettext.sh, gd.sh, ruby.sh, flvtool2.sh, lame.sh,
codecs.sh, libogg.sh, libvorbis.sh, vorbis-tools.sh, libtheora.sh,
amrnb.sh, amrwb.sh, liba52.sh, facc.sh, faad2.sh.

That's exactly all the files just before ffmpeg itself!

I know the error has to do with a library. However, I'm not familiar with
libraries. The error message says:

/usr/bin/ld: /home/xxxxx/lib/libz.a(compress.o): relocation R_X86_64_32
against `.rodata.str1.1' can not be used when making a shared object;
recompile with -fPIC /home/xxxxx/lib/libz.a: could not read symbols: Bad
value

BUT, when I look at my zlib log file(sharedhostffmpeg.1.0.2.log.15939), no
errors show up.

Does anyone know how to recompile with fPIC?

Message-ID: <39275A98-CB57-4754-AB0D-5C0718DD7342@13thlab.com>

Hi!

I'm developing something similar to the AR.parrot iPhone app for those who seen it. What I want to do is to stream the camera from a iPhone including extra sensory data (totally 6 double values) to a computer over wifi. I'm writing both the sending and the receiving application so the format does not to follow any standards. 

So far I got a MJPEG encoded stream using a MKV container sending the camera frames from the phone to the computer. I'm now trying to figure out how the send the data. I've seen there are something called data streams (AVMEDIA_TYPE_DATA) but I haven't figured out how to use it and which containers that support them.

Best,

Daniel Henell

Message-ID: <CALR4AhRj7J2bRpXav8aopFeSi7uEs3C2vkvQwY7ffn9zKrcyOw@mail.gmail.com>

Hi,

I'm trying to get ffmpeg working with Red5.

I have a stream being captured by Red5 and made available via rtmp.

ffmpeg works fine if I try to read an rtmp stream from Flash Media Server.

However if I use the same command attempting to connect to Red5, I just get
an error "Operation not permitted" without any additional clues in the
debug.

The Red5 log shows that the connection from ffmpeg was made and the play
command was received, then nothing else.

Here's the ffmpeg output:

ffmpeg -loglevel debug -i "rtmp://server2/live/livestream" -y  -c:v libx264

Thanks for trying to resolve a potential misunderstanding but I know what
config.log is for and I do check it every time configure fails and the
config.log contained the same text as was output by configure, i.e. no
additional information regarding why it failed for that library in that
particular case. That's what I was trying to say.

Cheers,

Robert

It is easier to still specify -target pal-dvd then afterwards overide

I have no clue as to why that didn't work.  If I remove the -vcodec, then

Pointers are appreciated.

Message-ID: <97B3FD97F9EB0B41965589D234B3236AA0D246@mail.streamnet.hu>

Hi!

I'm recently trying to generate picture-in-picture videos with ffmpeg, and I've run accross with some issues when handling videos with different lengths.
The normal situation with equal lengths works well with the following command:

                ffmpeg -y -i main.mp4 -i pip.mp4 -r 25 -t 20 -filter_complex "[1]scale=iw/5:ih/5 [pip]; [0][pip] overlay=main_w-overlay_w-10:10" -b:v 600k -c:v libx264 -f mp4 out.mp4

However, different lengths causing some problems:
                Case 1: Main video is LONGER:
                               The main video has no problems and goes all the way to the end without errors, but the overlay freezes when reaching the last frame.
                               I've added the 'repeatlast=0' option to the overlay filter hoping that it'll solve the problem: '[0][pip] overlay=main_w-overlay_w-10:10:repeatlast=0', but all I've got is this error message:

                                               [overlay @ 00000000021c7680] Option 'repeatlast' not found
                                               [AVFilterGraph @ 000000000228e760] Error initializing filter 'overlay' with args 'main_w-overlay_w-10:10:repeatlast=0'
                                               Error configuring filters.

                               What's wrong with the syntax? Is it possible to make the PIP image dissappear when it has reached the end?

                Case 2: Main video is SHORTER:
                               Both main and overlay stops at the end of the main video.
                               Since I need full length, I've put the time ('-t') option in the command with the length of the longest file (altough it has no effect).

                               Surprisingly, when I've mixed the audiochannels with 'amix' filter, ffmpeg generated a full length video, but the picture freezes at the critical point. Sound can be heared full length of the recording. The main video is usually containing still images, (like text, pictures, diagrams, etc.) so this issue is not a big problem in this case.

                                               ffmpeg -y -i main.mp4 -i pip_long.mp4 -map 1:1 -r 25 -t 20 -filter_complex "[1]scale=iw/5:ih/5 [pip];[1][0]amix=inputs=2:duration=longest;[0][pip]overlay=main_w-overlay_w-10:10:repeatlast=0" -b:v 600k -c:v libx264 -f mp4 out.mp4

                               It gives repeatadely this warning after reaching the edge:
                                               Buffer queue overflow, dropping.     703kB time=00:00:19.80 bitrate= 290.8kbits/s
                                               [Parsed_overlay_2 @ 0000000002098340] Buffer queue overflow, dropping.
                                               Last message repeated ### times

                               So, is it possible to make the overlay play after the main layer is frozen? Is there any workaround for this, like, filling the shorter video with the last frame, before the overlay filter?

                               I'm using zeranoes' ffmpeg build version N-49610-gc2dd5a1 on Win7x64.

                Thanks in advance!

Command line and complete, uncut console output missing / 
works fine here.

The repeatlast option was added in April, you are 
using a version from February.

For now I got the latest static compiled x86 32 bit version and ran it using
the same options and it worked.  Plus, the output worked on my Blu-ray
player via the NAS box DLNA server.

Hmm, I'll try it with a newer version, thanks for the hint!

Anyways, here's the full command line output regarding case 2:

Sniffing connection, and looking at the packets dump with e.g.
wireshark should help to investigate the issue.

Subject: [FFmpeg-user] C920 h264 ffmpeg empty output file
Message-ID: <1367930486543-4658914.post@n4.nabble.com>

Hi!
I am trying to set up rtp stream from my camera C920 with ardware-based
coder to h264. 
The frist step was to save encoded h264 directly from camera:
setting camera for right format:
v4l2-ctl -d /dev/video1 --set-fmt-video=width=800,height=448,pixelformat=1 
v4l2-ctl -d /dev/video1 --set-parm=30

launching ffmpeg
./ffmpeg -f v4l2 -input_format h264 -i /dev/video1 -c:v copy output.mkv

Log <http://pastebin.com/VnRRxLfu>  

Output file contains no frames (its empty)
frame=    0 fps=0.0 q=-1.0 Lsize=       1kB time=00:00:00.00 bitrate=N/A    
video:0kB audio:0kB subtitle:0 global headers:0kB muxing overhead inf%
Output file is empty, nothing was encoded (check -ss / -t / -frames
parameters if used)

Message-ID: <97B3FD97F9EB0B41965589D234B3236AA0D29C@mail.streamnet.hu>

Okay, tested it with the newest build, and works like a charm!

Regarding case # 2, I managed to come out with a workable solution, and I would share my results with you. Here's the command (it works with short main / long overlay videos and vice versa):
 
	ffmpeg -y -i pip3.mp4 -i pip2.mp4 -r 25 -filter_complex "nullsrc=size=688x320:duration=20, lutrgb=r=0:g=0:b=0 [bg];[0]scale=688x320 [main]; [1]scale=288:162 [pip]; [0][1] amix=inputs=2:duration=longest;[bg][main] overlay=repeatlast=0 [base];[base][pip] overlay=main_w-overlay_w-10:10:repeatlast=0" -b:v 600k -c:v libx264 -f mp4 out01.mp4

First, the program generates a blank "canvas". (nullsrc=size=688x320:duration=20, lutrgb=r=0:g=0:b=0)
Size attribute is nessesary, because the default value is realy small. Duration is also an important part, if you forget it, and your main record is shorter, ffmpeg will sit in an endless loop for some reason.

Next, I rescale the size of the main video, so it will not appear to be trimmed down. I have no idea why, but when I miss this step, the video  resolution will be same as the second input. It's especially problematic when you have a large main, and a smaller overlay resolutions. (Does anybody have any idea about this?)

Then, I apply the main layer to the black picture (which is as long as the overlay), and in the next step, apply the overlay to the output of the previous step. 

regards,
Gergely Luk?csy

Please do not use external resources, always

on the mailing list.

Does playing with ffplay and transcoding to 
another codec with ffmpeg work?

Someone let me know how to specify profiles in latest ffmpeg.

Setting -profile:v seems to have no effect. All the following produce "profile Constrained Baseline, level 4.2" output profiles.

Ricardo, this complete working example may help:


The html5 page can be served by apache, lighttpd and probably more. It needs the file extensions set, but lighttpd and apache have this by default. The required HTML 5 page ("html5.html") in its simplest form is :

Just put it in the root folder of your website (/var/www/ in my case) and make a subsequent subdirectory (live), writeable by ffmpeg,? where the hls segments and index file can be written)


The command for starting ffmpeg, live streaming a webcam in the format that can be displayed by an ipad 1below is essentially derived from the x264 encoding guide, the hls settings from extensive googeling.


ffmpeg -v verbose -f video4linux2 -vcodec mjpeg -s 640x480 -r 10 -i /dev/video0 -c:v libx264 -crf 18 -profile:v baseline -maxrate 400k -bufsize 1835k -pix_fmt yuv420p -flags -global_header -hls_time 10 -hls_wrap 6 /var/www/live/mystream.m3u8 


Point your ios device to http://YourIPAdress/html5.html after 30 seconds for the first two .ts files and the index file to be created.

Cheers

Ah... reversing the order of profile + preset seems to work...

Might be good to catch + report this or auto-reverse them.

Hello,

I've had similar issues with this and I would try 2 things:

El 07 may 2013 a las 02:45, Ricardo Kleemann <ricardo at americasnet.com> escribi?:

Here's the ffmpeg output:

ffmpeg -loglevel debug -i "rtmp://server2/live/livestream" -y -c:v libx264

Subject: [FFmpeg-user] No video for some part of the segmentation from FFmpeg
Message-ID: <CAL-NfOWquNbZRZyzFZMLa9_8jvGhy8mYkf_n8zfJzqf8zLzGnQ@mail.gmail.com>

I am segmenting a 20 minutes long video to hundreds of small clips . The
command is like "ffmpeg\\ffmpeg" -i nx_1.avi -ss 399.37 -t 1 ka1_2.avi".
(The ffmpeg is in a subfolder.)  It works very well for most of my video
files. The problem is one file, for that file, some segmented clip only has
audio, the relevant video obviously not was written into the clip. (Please
see the attached log file). But the segmented clips in other part the video
are good. Both audio and video are ok. I tried to segment a longer clip to
encircle the problematic part of the original video and replay it. The clip
plays fine until the problematic part, it froze at the beginning of the
problematic part.

How can I solve this problem?

Subject: [FFmpeg-user] Resizing dvb streams keeping Aspect ratio
Message-ID: <CAOwYNKYy=wv-VRzn_DjeDNMJ3rB0t9rB8RERceanNAsmUKT9Ag@mail.gmail.com>

Hi

I do lot of transcoding of DVB captures, currently to mp4 (h264), in two
stages.

One to an intermediate files so I can cut the adverts and then a final mp4
file

As people may be aware, at least in the UK, these TS streams can contain
several resolutions/Aspect Ratios, typically the program, adverts and
station blurbs can each be different.

However at least with mp4 the diffent resolutions seem to get transcoded to
one resoltion

Subject: [FFmpeg-user] What is my problem with concat?
Message-ID: <20130507142743.7ae48c4c@zooty>

I've been working out how to do frame accurate (or
near enough) editing out of commercials from .mpg
files I download from my TiVo (which have no doubt
gone through all kinds of nonsense with cable
companies inserting commercials and wot not).

I finally found that using -ss after the input
file to seek by reading from the beginning of
the file to the commercial-free segment I want
to encode was the only reliable way to get each
segment to start where I want and have audio
properly in sync. (The process of finding the
timestamps is a different adventure :-).

I then do this to concatenate the individual
segments:

ffmpeg -f concat -i files.concat -c copy out.avi

That has been working flawlessly until a show I
recorded last night. If I play the individual segments
they are all properly synced, but after I concatenate
them, the audio goes out of sync at some point in the
resulting files.

If I do an ffprobe -show_streams on the individual
avi files, I see things like this:

video streams duration: 479.412267,483.683200,etc.
audio streams duration: 479.496000,483.720000,etc.

That seems like enough extra audio to get out
of sync if it is just cramming the video streams
and audio streams together.

Is that what is likely happening? Is there some way
to fix it?

Should I generate some uncompressed audio stream
that can be cut easily at any timestamp and re-encode
for compression only after everything is together in
one piece?

If anyone is interested in vast details about
the scripts I'm using you can find them at:

I've tried all these options still no change :/.

I tried some other method using some soft which grab h264 stream from camera
and put in on pipe so ffmpeg can read it:
i've got that soft from  here
<http://www.oz9aec.net/index.php/gstreamer/473-using-the-logitech-c920-webcam-with-gstreamer>  

While using command:
./capture -f 640x480 -c 5000 -o | ffmpeg -an -i - -vcodec copy -f mpegts
udp://192.168.1.151:10000
I am able to see streamed video but it is delayed like 2 or 3s. Which is
sadly unacceptable for me...

Can you check, using ffprobe -show_packets for example, that the point where
the audio goes out of sync corresponds to a timestamp reset in the source
file?

The effect you are experiencing is because of -preset:v ultrafast. This
preset is incapable of producing anything better than baseline. Try the
'slow' preset and you should get a high profile stream. Also, do not confuse
level with profile, they are not related to each other.

But if the error were related to --enable-librtmp wouldn't I also have a
problem reading rtmp input streams from Flash Media Server? It works fine
with FMS

thank you.

Hi Hombibi,

Why are you using MJPEG as the codec? Would be an unusual codec to find in
an x264 guide.

If you want to stream low latency HLS from a local capture use something
like this which just grabs the desktop:
ffmpeg -f x11grab -s `xdpyinfo | grep ?dimensions:?|awk ?{print $2}?` -r 25
-i :0.0 -pix_fmt yuv420p -vcodec libx264 -acodec libfaac -r 25 -profile:v
baseline -b:v 1500k -x264opts keyint=25 -s 640x360 -map 0 -flags
-global_header -f segment -segment_list index_1500.m3u8 -segment_time 1
-segment_format mpeg_ts -segment_list_type m3u8 -segment_list_flags +live
-segment_list_size 2 segment%05d.ts

As fast as you can afford! Seriously. For a 2Mbps (assuming that is what
you mean by 2MB or do you mean 2MegaBytes?) stream I personally wouldn't
start with less than a 4 core system so you don't run too hot.

I bought some 4 socket 16 core AMD servers and found they were quite
adequate for ffmpeg encoded.

I can run -show_packets, but I can't interpret the output :-).

What would indicate a reset?

(I also can't pinpoint the time of the audio sync glitch because
there is a lot of non-dialogue action leading up to the dialogue
where it becomes obvious the audio doesn't match the actors lips).

Hi Andrew,

I use the MJPEG codec to select the compressed (mjpeg) stream from my webcam. I believe (...)? it requires a little less cpu and provides a little better picture quality than the raw video stream which is the other option.


On your comment on reducing latency: I see that you have configured the stream to have only two segments, with a length of 1 second. So aims this approach to reduce the available stale data as much as possible? Will try that. Thanks.

Hi Hombibi,

Why are you using MJPEG as the codec? Would be an unusual codec to find in
an x264 guide.

If you want to stream low latency HLS from a local capture use something
like this which just grabs the desktop:
ffmpeg -f x11grab -s `xdpyinfo | grep ?dimensions:?|awk ?{print $2}?` -r 25
-i :0.0 -pix_fmt yuv420p -vcodec libx264 -acodec libfaac -r 25 -profile:v
baseline -b:v 1500k -x264opts keyint=25 -s 640x360 -map 0 -flags

How could there be audio in a raw video file? Raw video means just that: a
file with just uncompressed video: no headers, no streams or packets
delimiters, just data.

Where does your "./rawvideo" file come from?

You have to look at the pts_time and dts_time, in each separate streams
(stream_index=X). The dts_time should be in more or less regular
progressively ascending order, and the dts_time should be the same values,
possibly with a small offset or slightly out of order if there are B-frames.
Something like that:

packet|pts_time=1350.840000|dts_time=1350.840000
packet|pts_time=1350.920000|dts_time=1350.880000
packet|pts_time=1351.120000|dts_time=1350.920000
packet|pts_time=1351.040000|dts_time=1350.960000
packet|pts_time=1351.000000|dts_time=1351.000000
packet|pts_time=1351.080000|dts_time=1351.040000
packet|pts_time=1351.280000|dts_time=1351.080000
packet|pts_time=1351.200000|dts_time=1351.120000
packet|pts_time=1351.160000|dts_time=1351.160000

(obtained with ffprobe -show_packets -of compact -show_entries
packet=dts_time,pts_time -select_streams 0 file)

You notice that dts_time progresses by 0.04 each time, meaning exactly 25
frames per second (audio would have a different interval, possibly
irregular, but still ascending), while pts_time are the same values, out of
order in groups of 4.

A timestamp reset would just be both values going back to 0 in the middle of
the stream, or possibly a value different from 0 but completely unrelated to
what comes before.

A rough estimate is enough.

Fing Cmo


I tested the stream on an ipad 1, ipad 3 and iphone 5.

HLS seems to be aimed at IOS devices and Safari, I don't think any other browser supports it out of the box.
It also works with VLC, on Linux and on Windows 8, in that case the webserver is not needed, vlc can be pointed directly at the m3u8 index file.

./rawvideo  - result of command:

/data/soft/bmdtools/bmdcapture -M 2 -A 2 -V 3 -m 8 -F nut -f ./rawvideo

this command capture from camera (via HDMI), and write to this file

more about this command: https://github.com/lu-zero/bmdtools


so, then i run ffmpeg i see follow:

So the format is nut, and the codecs are rawvideo and PCM.

What do you want to do exactly?

Subject: [FFmpeg-user] Audio glitches and distortion when recording and
	direct play
Message-ID: <1368014292566-4658945.post@n4.nabble.com>

Hi,

I have entered a bug in the ffmpeg bug track but I'd like to know if someone
have a workaround for the issue.

The ticket is #2504  here <https://ffmpeg.org/trac/ffmpeg/ticket/2504>  
I uploaded some audio file as sample as well.

To sum-up, when I record with the  command
ffmpeg -debug 1 -vn -f alsa -ac 2 -channel_layout stereo -i hw:0,0 -c:a
pcm_s16le /Store3/Test/pcm_`date +%m%d_%H%M`.wav
I get glitches and distortion.
With the following appli,
Audacity
With Alsa, input: default then pulse then ALC892 (hw:0,0)
Result: with these 3 different parameters, audio is perfect.

recordmydesktop
input: DEFAULT
result: audio is perfect.

gnome-sound-recorder 2.29.91
Record from input: Capture
format flac, ogg, pm3
Result: with these 3 different formats, audio is perfect.

arecord
arecord -f cd -t wav out.wav
Result: audio is perfect.

VLC
input hw:0,0
Result: statics after sound

As the command is very common maybe there is a workaround. In fact I found
out this issue when I was recording audio and video from a S-VHS tape with
pcm and ffv1 codecs.
I think there is a link between ffmpeg and VLC as they are the only with the
issue.

Any help is much appreciated.

Hi,

I have the working command below to stream my webcam to IOS devices:


"ffmpeg -v verbose -f video4linux2 -s 640x480 -r 15 -i /dev/video0 -c:v libx264 -profile:v baseline -preset superfast -tune zerolatency -pix_fmt yuv420p -flags -global_header -hls_time 3 -hls_wrap 10 /var/www/live/mystream.m3u8"

The objective is to transform the -c:v .......... m3u8 part to a ffserver.conf so that it can be published with other live streams. 

The ffserver.conf outline below generates one .ts file, the hls segmenting does not seem to work. I can't find? documentation on the format of the ffserver.conf file configuration options, or on what options can or must be added. 

?To move further I would appreciate some help to gain some insight on how the segmentation options hls_time and hls_wrap must be added to the server.conf file

Well, I found absolutely nothing that looked irregular about the times
in the packets (whipped out a little perl script to compare various things),
but I'm pretty sure I have decided that I need to hit '-' 3 times in mplayer
(-300ms audio delay) right at the point where the 3rd file gets concatenated
in the list of the 6 files that make up the whole video.

I guess I can try inserting (or is it deleting) 300ms of silence in the audio
at that timestamp and see if it comes out right :-).

Subject: [FFmpeg-user] Playback issues with HLS on Android
Message-ID: <04DB7686-2B70-4878-A986-48505D4AB50F@renecalles.de>

Hi all,

i'm trying to create segmented H.264 video in MPEG-TS container with AAC-Audio in Baseline profile. Strangely FFmpeg "only" creates "Constrained Baseline" video, even when using '-profile baseline' option. The reason i'm asking is because the segmented HLS video is working fine on any iOS6 device but not on Android 4+ devices.

The video starts as expected on Android devices, plays the audio fine but the video is running kind of slow motion. This behavior is better when using "Main" profile but then on segment change it gets blocky.

Anyway it doesn't look like it's an issue of the segmenter as if i encode Baseline video using a commercial encoder and segment it using FFmpeg, it plays absolutely fine on all devices.

It seems to me that there is an issue with FFmpeg encoding in "Baseline" profile as FFprobe detects it as "Constrained Baseline" but the commercial encoded one as "Baseline". So, the detection of the profile seems right.

Does anyone know what's maybe going wrong? Maybe it is only a wrong header information FFmpeg produces?

Thanks all and best regards,
Ren?

Subject: [FFmpeg-user] Decode Dolby Pro Logic II
Message-ID: <518B6999.3010501@gmail.com>

Hi list,

I saw that libswresample is able to matrix encode 5.1 surround to stereo 
using '-matrix_encoding dplii". However, I just bought an enhanched CD 
which had a download link to Dolby Pro Logic II encoded stereo files and 
I don't have any hardware capable of decoding, so I was wondering 
whether ffmpeg is able to decode this?

I couldn't find any clues on this. Strange, that it is able to encode 
but not to decode?

Any help would be greatly appreciated. Thanks in advance

You sure you are not mixing codec with downmixing?

Uhm... what do you mean by that? I'll try to be clearer.

According to the download page, these files have to be played with a 
Dolby Pro Logic II-compatible system. They look just like normal stereo 
files to me (i.e. no AC3 or DTS) so I guess they're matrix 
encoded/downmixed. As I don't have hardware with Dolby Pro Logic II, I 
would like to 'upmix' this in software, so I can play it properly. It 
found a downmix option in ffmpeg, but no upmix option.

Anyone, who knows more about this?

There's very little documentation on the ebur128 filter.

It appears the way this works is via two pass processing.

1) first pass builds normalization data

2) second pass applies data to audio stream

If there's an example of this somewhere, pass along the link.

Transcoding to multiple formats is done with tee muxer.

Tee muxer can only be used to mux into different container afaik. For different resolutions you need to encode your video 3 times in that case. Altough it is possible to chain this in a single command.

This should give you a hint how to do it.

'This filter takes an audio stream as input and outputs it unchanged.'

As far as I can tell, it just logs information about the audio,
without changing anything (well... it looks like it can write some
loudness-based metadata to the audio stream). There are some examples
of its usage at the documentation.

Subject: [FFmpeg-user] Creating MP4 fragments in separate files
Message-ID: <CAAJzrgwhTJTCjsZM7AYVfb0975mLbcZo-eUEE20OriDguD95Fw@mail.gmail.com>

[I originally sent this as a unsubscribed user, but it's been awaiting
moderator approval for 24hrs... sorry for any unintended duplicates]

Hi,

I'm attempting to use ffmpeg to connect to an RTSP h.264 source and store
the video stream as a series of MP4 fragment files. The purpose is to serve
up the fragments to a web browser (Chrome) via the MediaSource API. I want
ffmpeg to continually write a new mp4 fragment file for each 4 seconds of
video with an incrementing file number... i.e. segment01.m4s,
segment02.m4s, etc.

I need the first segment file to contain the "moov' box with no 'mdat'
media data. Each subsequent fragment file should have a 'moof' box and an
'mdat' box containing the video for that video fragment.

I've tried 2 different approaches (to no avail):

(1)  ffmpeg -i rtsp://<ip>/stream1 -codec copy -map 0 -f segment
-segment_time 4 -segment_format mp4 segment%d.m4s

This creates separate mp4 files for every 4 seconds of video, but each file
is stand-alone... i.e. each one has it's own 'moov' box... they aren't
fragments of the same stream, but rather independent streams.

(2) ffmpeg -re -i rtsp://<ip>/stream1 -codec copy -f mp4 -movflags
frag_keyframe+empty_moov -frag_duration 4 camera.mp4

This creates a single mp4 file, with a single 'moov' box and multiple
'moof' boxes for each 4 second interval... the problem is they're all in
the same file.

Any help would be greatly appreciated... even if there's a separate tool I
need to run the data through (I've tried using MP4Box w/ ffmpeg-generated
MPEG2-TS segments, but I get PTS errors).

Thanks!

I don't think this is implemented, could you provide

Please note that "Baseline" (may) contains many features 
that are not supported by any H264 decoder while 
"Constrained Baseline" was defined later to define the 
actual Baseline features, as users (decoders) always 
expected them.
(FMO, ASO, RS)

Or in other words: "Constrained baseline" is what you 
would expect from "Baseline" (which is something else 
that you certainly don't want to use).

Wouldn't decoding be just reverse of downmixing (thus
upmixing) as done in libswr and explained on wikipedia?

Hi Carl,

thanks for your response. 

So, Wikipedia's profile table is not correct as it says Constraint Baseline has less features (FMO, ASO, RS) than Baseline and the library is using Constrained Baseline wording for Baseline at all?

For the bad playback on Android, do you have any idea what could get wrong? A missing option? Or should i move this topic to x264 user list?

Thanks and regards,
Ren?

Subject: [FFmpeg-user] ffmpeg created prores 444 still not identified
 correctly by Quicktime player?
Message-ID: <518BF3A9.9060306@ringsidecreative.com>

Last year I had introduced a thread about an issue where Prores 444 quicktime movies created with ffmpeg and the prores_kostya codec were failing to be identified as 444 by the Apple Quicktime player. See thread: http://ffmpeg.org/pipermail/ffmpeg-user/2012-September/009521.html for details.

By the end of the thread, the consensus seemed to indicate that the fourcc was being set incorrectly to apch (the reply actually stated apcn) instead of the correct ap4h but the pixel format was correct. I believe a patch was being tested.

I recently downloaded a newer version of ffmpeg and attempted the same files with the same commands (substituting "prores_ks" for "prores_kostya" which appears to have changed). The issue still appears to exist. Is this still a known issue?

Here is the ffmpeg command and output that leads to the incorrectly identified file:

ffmpeg.exe -i "C:\Server\Jobs\MediaConversionFormats\QT\Alexa\AlexaProRes4444QT_A.mov" -vcodec prores_ks -pix_fmt yuv444p10le -profile:v 3 -acodec copy -f mov "C:\Server\Temp\Output\AlexaProRes4444QT_A\AlexaProRes4444QT_A.mov"

Regarding the fourcc issue, the patch somehow isn't committed. (I don't
know anything about coding so I can't decide if the patch is good enough to
be committed.)

For the alpha channel in the ProRes 4444 (which might not be applicable to
your issue), the issue is still open on trac.

Hi,

I am doing some experiments regarding downmixing of 7.1 channel to stereo
using ffmpeg.
Can anyone please give me some link, from where i can download 7.1 channel
wma, aac and eac3 input test vectors ?
I searched the net, but could not find any good link.

Regards,

Please do the test with wav files, other sources may 
have different initial problems.

Where you able to test a sample that shows if Chroma 
subsampling is done correctly or not?
I don't think decoding can work at all if the decoder 
(QuickTime) does not (internally) detect the right 
colourspace (444).

Hi Carl, all,

after some investigation i found a solution which seems kind of weird 
but actually is the only option which works.
So, for others who may struggle with the same issue here's a summary:

Works not:
Encode H.264/AAC video and segment it in a single command!!

Works:
Encode H.264/AAC video to MP4 Container, and in separate process, copy 
the bitstreams (-c copy), set the bitstream filter (-bsf:v 
h264_mp4toannexb) and segment it using (-f segment).

Anyway it would be great why FFmpeg behaves that way as at the end 
there are MPEG-TS chunks.

Best
Ren?

Oh, if it happens at the stitch, it is another matter. Can you show the
timestamps of the few first and last packets of all three first files, in
both audio and video streams (remove -select_streams in the ffprobe command
line in my previous mail)?

I uploaded a sample to upload.ffmpeg.org/incoming/Dolby Pro Logic II 
sample-cut.WAV

I thought I got it yesterday after some scripting with SoX, but the 
result was disappointing. Today I discovered there was something wrong 
with the parameters. I also found this document that made me think it is 
more than just 'inverting the matrix': 
http://www.dolby.com/uploadedFiles/Assets/US/Doc/Professional/209_Dolby_Surround_Pro_Logic_II_Decoder_Principles_of_Operation.pdf

Anyway, thanks in advance

I did manage to get a file that plays right by using sox to build a new
audio stream with 300ms of silence stuck between file 2 and file 3, but
here are the leading and trailing packets for the first three files

(I think I see the problem here - about 300ms with no audio,
no doubt due to some weird corruption in the .mpg file
from the TiVo :-).

Subject: [FFmpeg-user] Translate dts to hh:mm:ss?
Message-ID: <20130510101214.62a59477@zooty>

If I encode a possibly corrupted (ntsc) mpg file, I sometimes see things
like this in the log:

[mpeg @ 0x2dc9300] Invalid timestamps stream=0, pts=71146986, dts=71146987, size=32539

Is there any way to translate those pts/dts timestamps into
a number of seconds so I can look at that time in the resulting
file to see if there is a problem there?

You need to know the time base. ffprobe -show_streams can show it, but for
MPEG-PS, it is always 1/90000.

Note that you will also need to subtract the start time to find the
corresponding frame in the output file.

Subject: [FFmpeg-user] audio playing too fast on ffmpeg
Message-ID: <1368205548438-4658977.post@n4.nabble.com>

I'm not sure if anyone else has ran into this but the audio is playing much
faster than the video. Here is a little breakdown. Any help would be great,
THANKS!

_Here is what I know_:

 * I know the sound being grabbed is correct because I made a playback
   test function.
 * I know the sound is being encoded into the video file because I can
   hear the sound when played in ffplay or any other player.

_Here is the problem_:

 * When the output video is played, the video starts off at the correct
   speed, but the audio is playing far too quickly.
     o For reference, my test output is supposed to be 20 seconds. With
       my current settings, this is 100 video frames and 100 audio
       frames at 5 FPS.
     o All 20 seconds of audio play in the first 5 seconds of the
       video, which shouldn't be happening simply because the audio and
       video are being encoded side-by-side (write_audio_frame() is
       being called directly after write_video_frame()).

_Here is what I have tried_:

 * Changing pts values before the encode, after the encode, using the
   native av_rescale_q() function to try and automatically set the pts
   value.
     o  I have done quite a bit of research on this and it seems to be
       the consensus that pts is supposed to be set before the frame is
       encoded into the packet, and I have a formula that should work
       for both the audio and video pts: 
         + frame_count * (1000/STREAM_FRAME_RATE) * 90
         + ^ frame scale              ^ getting ms                    
               ^ pts is apparently supposed to be time * 90
 * Reducing the frames per second to a safe value (well-below the
   potential of the system)
 * Switching between the av_interleaved_write_frame() and the manual
   av_write_frame()

_Here is what I think the problem could be_:

 * I've always thought it could be the pts/dts that are off, as those
   are what are supposed to be controlling the speed/when the sound is
   played...but considering how many different ways I've modified these
   and tried things that I think should have worked with my
   understanding of them and how little any of my trials have mattered
   in the output file, I'm beginning to think the possibility of this
   being the problem is getting slimmer and slimmer.


_Technical details about the audio data (just in case)_:

 * Using SFML (Built off of OpenAL) to grab the data
 * Developing on Windows, audio data is being grabbed from the muxer
   with the microphone disabled.
 * The sound data is PCM, 16 bit (stored as int16_t*)
 * I started off using an algorithm that interlaced the audio with the
   video manually by using a method of
     o if audio->pts < video->pts, write another audio frame
     o else write video frame
 * I now just encode an audio frame after every video frame because it
   /should /sync itself, considering the audio is being grabbed while
   the video is being encoded
 * I have access to the raw buffered audio data (int16_t*), the sample
   rate (uint), the channel count (uint), and the sample count (size_t).

After struggling with HLS on Android I can confirm your suggestion works :)

I actually created a HLS test page for this:
http://walterebert.com/playground/video/hls/

I hoped this would also improve Flash playback. But changing bitrate
still disrupts the audio stream. Not sure if this is a HLS or Flash problem.

Cheers,
Walter

Hi all

 

How to decrease latency while transcoding and streaming from live source
like DVB card (IPTV).

 

When starting to watch , the audio begins before the video by 3 seconds.

Any thing to do to fix it ?

 

Thanks in advanced.

Hi Walter,

good to hear this helped you. For me there is a issue left on Nexus 4 as video sometimes get scrambeled, like a missing frame or something. This happens only on Nexus 4, not on Galaxy Tab or Galaxy S3.

Really strange and i don't have any clue why. 

Hope someone on this list can help.

Best
Ren?

Hi Walter,

I looked at your test page and found that your 3rd example has a typo in
the mime type: appplication/vnd.apple.mpegURL

It should be application/vnd.apple.mpegURL

(Note your mistaken triple "p")

Hi Walter,

Thanks for the test page.
I can confirm that 1st & 3rd HTML5 videos play on my Galaxy Note 2.

If you don't mind, can you provide the ffmpeg commands you used to
generate the video segments?
Do the exact segments play on iDevices as well?
I guess I can test those later on iPhone :)

Thanks,
FC.

The commands are on Bitbucket:
https://bitbucket.org/walterebert/ffmpeg-hls/src

> Do the exact segments play on iDevices as well?
> I guess I can test those later on iPhone :)

The segments play on iOS devices. Although there is a problem on older
devices with a resolution of 480x360 pixels (and iOS 4.2):
- The first video can be started, but actually does not play because it
contains higher resolution streams.
- The 2nd and 3rd video cannot be started.
- The 4th video with the 480x270.m3u8 stream play just fine.

I would have expected that the device would automatically select the
highest resolution it can play.

On iPad the videos play without any problems. iPad 1 cannot play full HD
(1920x1080) or higher. That is why the highest resolution on test page
is 1280x720 pixels.

Thanks Timothy for catching that. I corrected the MIME type.

Message-ID: <CANZNk82Dj+ujEZheDh8s9yWaOGqVgUUGjEkyMvnQsTDbsn5NJA@mail.gmail.com>

I am not keen on such thing as objects recognition on image. I'd like
to know if there is filter available in libavfilter, or in the libs
pluggable to it, or even another graphical package, to do what i ask
for: to thicken exactly thin curved lines (if it helps, let's say
there's a limit of its width), these lines of interest all have
certain color.
The application is processing terrain satellite photos, to make small
roads and trails more noticeable.

what is "your package"?
ffmpeg itself is *source code*

yes, i have heard from people which managed to find a working
window sbinary or even compile it at their own, said from a suer
which did not touch windows after 2006 seriously

It's possible to get compiled versions of ffmpeg for both Linux and Windows.

The only problem I've ever had with windows versions is that they tend to be considered outdated when you ask questions about them on this list. That always seems a little unfair, since "outdated" in terms of ffmpeg seems to be a matter of hours, but it's only a problem if you let on...

Most people that compile FFmpeg for Windows do that on Debian or
Ubuntu...

These Windows binaries are compiled on Debian, for instance:

That is a lie.
True is that only current versions of FFmpeg 
are supported on this mailing list, no matter 
for which operating system.

Please do not top-post on this mailing list, 
it is considered very rude.

and your definition of "current" is "latest snapshot"
this is one of your most answers on the list

Message-ID: <E81AB352-206A-490C-B927-19E53DFF6D78@up4.com>

Hi Guys,

Please find below the log I get when I convert XAVC 422 10-bit 4K material into ProRes with the latest trunk.

I am worried about the 5 MXF parsing lines:

[mxf @ 0x2bbcf20] could not resolve sub descriptor strong ref
[mxf @ 0x2bbcf20] source track 11: stream 9, no descriptor found
[mxf @ 0x2bbcf20] Stream #9: not enough frames to estimate rate; consider increasing probesize
[mxf @ 0x2bbcf20] decoding for stream 0 failed

And the post-processing line: "Clip0042.MXF: Operation not permitted".

The output file looks fine. But I would like to know what those error messages mean and eventually, to get rid of them.

Regards,

Vincent

I just wanted to say the Zeranoe builds work great on Windows (I use them
constantly) and there is really no major diff between them and the normal
Linux version which I use occasionally but my main converting PC is Windows.

Also I feel the ffmpeg list has been very supportive of the Windows builds,
as I have gotten support and even had a "bug" fixed where -ss would not
take over 24 hours.

AFAIK, without reencoding it's impossible.
http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC#Levels
You need to change codec settings (when encoding) to get another 'Level'

Improvements on the filter welcome (like adding more algorithms)

Hello,

should this work?

I only added the "-fflags +genpts" options because of these suggestions: https://ffmpeg.org/trac/ffmpeg/ticket/1979 , but it doesn't change behaviour.

Muxing h264 in mkv should work, unfortunately timestamps 
are not read from some h264 streams, this is a known 
problem (and apparently not trivial to fix).

It does not always help.

Message-ID: <CA+QdfqXcz58Bnvpm5sTpgD_exvVD=ODc9kEfm4+cE6x_gLNZEQ@mail.gmail.com>

  Please respond

I have ubuntu 13.04 Desktop (32 bit ) OS on my PC.

When i am trying to install ffmpeg on my PC it shows error like this




./configure --enable-gpl --enable-libass --enable-libfaac
--enable-libfdk-aac --enable-libmp3lame \
>   --enable-libtheora --enable-libvorbis --enable-libvpx --enable-x11grab
--enable-libx264 \
>   --enable-nonfree --enable-version3


*ERROR: libfdk_aac not found
**
If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user at ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.*


And i am new to ffmpeg



Thank you

Prathap.M

Remove --enable-libfdk-aac (and --enable-version3 which is not
required).
Or install fdk-aac as shown in:

https://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide

See the end of config.log for additional clues. If you need additional
help please include the relevant section of config.log (the last 50
lines are probably more than enough).

I assume you mean that you're compiling a version of ffmpeg on your
computer? Look at this guide, and make sure you follow all the steps:

I don't think there a big differences with Windows and Linux versions.
If you are a Windows lover don't change it.
For me the Linux community a nice and overwhelming force in the short
history of software development.
It doesn't focus on making money but on ideas and realising them. It is
free, your data isn't used for advertisement it is very powerful as a
server and scalable. And if you don't like things you can change them and
distribute your version.

Did you build the libs and the program differently?

Complete command missing.

Subject: [FFmpeg-user] Strange Audio Rate Issues
Message-ID: <1368420207.7737.13.camel@zeeman>

Dear FFMPEG Users,

Apologies for the hopefully obvious question, but I've been struggling
with this for a few days and it's driving me nuts.

I'm trying to do a screen capture from my desktop with captured audio. I
am starting with the most trivial command I can generate to do this:

ffmpeg -f alsa -ac 2 -i pulse -f x11grab -r 15 -s 1920:1080 -i :0.0
-acodec libmp3lame output.mp4

The issue is that when I use this command to simultaneously do a screen
capture along with audio capture from my pulseaudio capture port set to
monitor it does not record at the proper audio rate, but claims it did.

Examples:

Video: https://www.dropbox.com/s/13hwuxd2p725re6/output.mp4
Audio: https://www.dropbox.com/s/vc15pvpvg74aj3q/output.mp3

The video clearly shows that the mp4 audio sample rate is 48000Hz, and
shows clearly that sox is generating a 440Hz tone at 48000Hz sample
rate. The audio file is directly outputting from sox into a file, and
accurately represents what I hear through my speakers.

As you can see, the mp4 file (same issue with avi, FWIW) has a frequency
shifted sine wave from 440Hz and drifts out of audio sync rapidly. You
can clearly see the levels on the mixer showing that it's not playing
when it should be (along with watching the play command).

This makes no sense to me; I've tried multiple audio codecs, multiple
output formats (avi and mp4), multiple manual audio rates, I tried
manually setting the video frame rate, but it all ends up the same.
Obviously, this makes recording a screen capture with correctly
synhronized audio in less constructed cases impossible.

Can anyone explain to me what is going on?

I am using ffmpeg version 0.10.6-6:0.10.6-0ubuntu0jon1

Best regards,
Brian

I think it is the latest release version, and I think the release version is more stable than the git version.
I build the libs and enable the pthreads today, the bug still exist. the output log is as follows:

Walter,

Just to correct and add to the test list.
I tested your HLS test page on the following devices on their Chrome
browsers.
Latest official OS/Firmware versions as of today.

Galaxy Note 2 -------------------- 1st AND 4th video play (No Flash).
Google Nexus 4 (Phone) ----- 1st AND 4th video play (No Flash).
Google Nexus 7 (Tablet) ----- 1st AND 4th video play (No Flash).
iPhone 4 --------------------------- All 4 HTML5 videos play (No Flash).
iPhone 5 --------------------------- All 4 HTML5 videos play (No Flash).
Google TV (Vizio VAP430) - ALL 5 videos play including the flash one.

Note that for Google TV, it plays in spite of your disclaimer:

"*Note:* AddType application/vnd.apple.mpegurl m3u8 #Does not work on
Android

So apparently it works on that Android :)

Thanks,
FC.

Subject: [FFmpeg-user] Color Shift when encoding DNxHD QuickTime video on
	Windows
Message-ID: <CA+JrDp3=LJadFU0CWcmP0x7rETVS4VQUHOjB6+pcd1Z9xLXQMA@mail.gmail.com>

Hi

I am a software developer working for an animation studio. I have been
tasked with creating DNxHD QuickTime videos which are then imported into
Avid Media Composer (An Editing Suite Application using DNxHD and MXF as
it's preferred codec and format). Our studio uses Windows 7. I have noticed
a color shift when comparing the media encoded by FFmpeg to the media
created by Avid when importing the frames directly (Note: Avid will encode
a DNxHD MXF from the image files on import). We create the QuickTime videos
ourselves because it reduces the import time given that Avid will only
change the video container without having to do any real encoding. I hope
this makes sense, I am not an expert in this area. I have compared the
output when using other software packages such as RVIO and Nuke. RVIO
doesn't match the video created by Avid but it also doesn't match the video
created by FFmpeg whereas Nuke is able to match the video created by Avid.
I am interested to learn about what causes the color shift. Attached is the
output from the FFmpeg command I am using and the output from an ffprobe
query on both an input image and the output video. Note: The input images
are in sRGB color space. Any feedback will be much appreciated.

I just tried to play the streaming media as a client of IPCAM (Hikvision
DS-2CD2012). It runs smoothly.

Here is the command:
ffplay rtsp://192.168.1.102:554/Streaming/Channels/1

Hi, thanks, we test it to decode h264 stream and the error log is as follow:

and you can see that the image of video is not correct. I search in the
internet, the earlist ffmpeg seems correct, but the latest ffmpeg seems not
correct. it seems some bugs in udp and rtsp, and make the h264 decode error.

Thanks

ffmpeg and ffplay certainly do rtsp.

What is the format of the out.264 file you are trying to stream? If it is a
VOD for it to play correctly would likely require it to be streaming hinted
mp4. Can you do ffplay or ffprobe on the out.264 file and send the results
of that.

You should also look at the sdp file generated by live555.

I use ffmpeg and libx264 to gernate the out.264, I think it is the h264
stream, yes ffplay can play it ,and but not correct in some frames. just
like the log I paste in the previous mail. I want to ust ffmpeg first, but
it seems that the bug has exist for a long time.I serarch in internet, and
someone report the bug in 2011.

It seems that the data received is not entact,which often happens at the
start of decoding the incoming stream video.
Does it go well after a short period?

Hi All,

Sorry to pipe in late but after spending a lot of time recently on Android
I can tell you there is no simple answer for HLS to work consistently
across all devices. The underlying issue is that every hardware variation
has a different video decoder chip and by nature this means that they all
have slightly different video players compiled which are then called via
JNI from the Android application layer.

Now while many of these players are deriviatives of ffmpeg/ffplay they are
often from way old versions.

Best bet is to only go with a single bitrate if you want it to work
reasonably well as multi bitrate will vary massively from device to device.
If you really want good Android support you need to go with a custom media
player and you can launch these via a webpage using an intent or just embed
them in an app.

For maximum compatibility I have also found that some Android devices don't
like a lot of variation between what they get in the playlists and what
they see in the segments so you should force keyframes so that the segment
doesn't have chop on where the next I frame comes. I have been using a
wrapper around ffmpeg to generate the keyframe string
https://gist.github.com/sinkers/5567058  though should time permit I would
like to get this into the ffmpeg codebase.

However if anyone was to map which variations of HLS work and don't work on
the many many devices it would be quite useful!

Regards,
Andrew

it happened even I tested on my own computer.
Yes, the video play correct after a short period, but every time I run the
ffplay, the output errors are the same. So I don't think it is a netwrok
problem.And the evnironment of our lan is very good

Thanks for your reply

is there a reason why you not strip repeated list-footers?

This looks too old, please test current git head.
Did you try with -sws_flags full_chroma_int ?

strip them simply from you replies as any footers, signatures
and disclaimers have to be stripped from qutotes to keep threads
readable

hi,
I have to generate 60s of black video with mute audio.
with the following commad line video track is always mpeg1. The -vcodec

ffmpeg -f lavfi -i color=c=black:s=720x576 -r 25 -vcodec mpeg2video -f
lavfi -i aevalsrc=0 -ar 48000 -ac 2 -acodec mp2 -t 60 filler.mpg

Could you explain why you want mpeg2video?
Afaik, a compliant mpeg2 video decoder can also decode 
mpeg1 video.

-vcodec mpeg2video needs to go somewhere after acodec. (after last -f x -i y)

I know mpeg1 can be decoded by mpeg2 decoder. But I also want ffmpeg to
respond to my commands.
Anyway moving -vcodec after -acodec worked.
Is there any doc to understand parameters order logic?

thanks

Subject: [FFmpeg-user] -vcodec copy encodes nothing (empty output file) with
	h264 input
Message-ID: <201305130644.54993.paul@hivetool.org>

I'm trying to stream from a Logitech C920 camera.  I want to put the camera 
into native h264 mode and use the -vcodec copy option to reduce the cpu load.   
That will work, right?  Ideally it will use a container that will embed in 
html and work with most clients (mp4? matroska? H.264?) but must handle a live 
stream.

When I use the -vcodec copy option with -vcodec h264 on the input, I get the 
Output file is empty, nothing was encoded message.

Doesn't work. No data to output file:

ffmpeg -f video4linux2 -vcodec h264 -s 640x480 -r 15 -i /dev/video0 -vcodec 
copy output.mkv

Works but cpu load is about 48%:

ffmpeg -f video4linux2 -vcodec h264 -s 640x480 -r 15 -i /dev/video0 -vcodec 
h264 output.mkv 

Works and cpu load is about 2%! BUT input stream is rawvideo (YUY2) yuyv422. 
(Setting the camera mode with v4l2-ctl to h264 doesn't help as ffmpeg changes 
the mode.):

ffmpeg -f video4linux2 -s 640x480 -r 15 -i /dev/video0 -vcodec copy output.mkv 

I've tried different output containers (mp4, swf) with the same result. I'm 
really trying to stream to ffserver but the above examples give the same 
result.

What stupid thing am I doing wrong?  I see others have the same problem but 
can't find any solutions.

(Not that it matters, but we are trying to monitor bee hives with a Pi: 
hivetool.org and click on the SWF link to see a live feed running on a PC with 
99% cpu utilization...)

Thanks!

Try generating it as an mp4 as live555 will likely need something like that
to convert to RTSP as probably can't handle raw h264 assuming that is what
your .h264 is.

I don't use live555 but a simple mp4 works fine in either DSS or Wowza e.g.
here is the Wowza sample file:

Does "-re" (an input option) help?

Sorry.  

No, 

ffmpeg -f video4linux2 -re -s 640x480 -r 15 -vcodec h264 -i /dev/video0 -
vcodec copy output.mkv

yields same result, Output file is empty ...

Thanks,

-re 
Read input at native frame rate. Mainly used to simulate a grab device.

So, I guess I should leave out the -r 15?

Didn't matter.  Still Output file empty.

You could try to add -vsync 0 (another input option).
Unfortunately, no developer owns such a device afaik.

Where you able to test a sample that shows if Chroma
subsampling is done correctly or not?
I don't think decoding can work at all if the decoder
(QuickTime) does not (internally) detect the right
colourspace (444).



I was not aware that the image needed to be tested. However as near as I can tell, the image quality does seem to indicate that it is being created using 444 (using a gradient that indicates banding more predominantly when 422). As far as I know, the problem was all about the fourCC not being set correctly.

Dear ffmpeg support,

I have a question about that information from your site:

"Note, ASF files often have .wmv or .wma extensions in Windows. It should
also be mentioned that Microsoft claims a patent on the ASF format, and may
sue or threaten users who create ASF files with non-Microsoft software. It
is strongly advised to avoid ASF where possible."

Is this information is still actual  and what is the source of this
information?

Best regards,

Mateusz Fruba

It is probably a color matrix issue. In most cases you will want to
use Rec601 for SD and Rec709 for HD when converting RGB to YUV, but it
depends on the destination. If the wrong conversion is used, the
colors will be slightly off (purple-ish or orange-ish skin tones,
difference in saturation). Look at this post for a good example

If the video does indeed conform to L4.0 and you just want to change
the metadata, that is possible. I'm not sure how to do it with ffmpeg
or if it's possible, maybe someone knows. There are other tools that
can do it if you don't need to integrate it into some current
workflow. Here is an example:

Am I right in thinking that the only differences between high at 4.0 and
high at 4.1 are in maximum supported bitrate, from 25 Mbit/s to 60
Mbit/s?

Yeah, it looks that way. (Going by wikipedia at least)

Message-ID: <1368462678466-4659052.post@n4.nabble.com>

Hello.

I am re-streaming a Live H264/AAC stream using ffmpeg (windows).  After
about 1 hour I'm getting the following error in the console:
 
Non-monotonous DTS in output stream 0:0; previous: 38226576, current:
31954543; 
changing to 38226576. This may result in incorrect timestamps in the output
file.

Here is the command I am using:

ffmpeg.exe -threads 0 -i "$rurl playpath=$rplaypath swfUrl=$rswfurl
pageUrl=$rpageurl live=1 " -map_metadata -1 -loglevel info -f flv -acodec
copy -vcodec copy -r 15 -aspect 16:9 -bufsize 12000k
"rtmp://localhost/$dapp/$dstream"  2> F:\Streams\$dstream.log
 

Any idea what this error message means and how to mitigate?  Here is a bit
more detail from the log, when the error actually starts...

negative cts, previous timestamps might be wrong
DTS 4294905094, next:4418668000 st:0 invalid dropping

changing to 4423587. This may result in incorrect timestamps in the output
file.


So you can see at that point the the DTS/PTS status message is completed
replaced by the "Non-monotonous DTS" error.  Also notice the "current" value
is negative and then climbs back to positive value.


Thanks for any insight.

Message-ID: <CAAJzrgxjSZmjKPv0URb0we0B_7bXLtMi8JZcVzCku2T8WGgF=A@mail.gmail.com>

Hi,

I have a series of ts segments (seg001.ts, seg002.ts, etc) that I want to
convert into mp4 fragment files... i.e. files w/ a 'moof' box instead of a
'moov' box.

I've tried ` ffmpeg -i seg001.ts -codec copy seg001.m4v`, but that
generates files w/ independent "movies"... each w/ it's own 'moov' box.

Is the segment muxer able to do what I want? I've been able to use it to
create a single file w/ multiple 'moof' boxes inside, but I really need
separate files for each segment (they are created live on-the-fly).

Thanks.

Well, from my own experience on RTMP streams, it really may give you
non-monotonic timestamps, so it is not a ffmpeg mistake.
The other question is - is there any problem with saved video? If
none, you may ignore this output.

I guess concat demuxer does what you need.
Below are links to official docs and usage examples.

Unfortunately, I'm not looking to concatenate all the segments into a
single file. I'm looking to generate a 1:1 relationship between seg*.ts ->
seg*.m4v... i.e. if I have 100 TS segment files, I want 100 MP4 fragment
files, but all those fragment files to be part of the same "movie" (i.e.
associated w/ a single 'moov' description).

Ultimately, my goal is generate the following:

seg001.ts -> init.mp4 (w/ 'moov' box) and seg001.m4s ('moof')
seg002.ts -> seg002.m4s ('moof')
seg003.ts -> seg003.m4s ('moof')
etc

I am not sure I fully understand what the feature you need. Looking
fast to available muxer options I didn't find something like that.
If you understand MP4 internal structure well, maybe you could look
inside libavformat/movenc.c to figure out how it behaves and what you
could change.

Hi Andrey.

First, thanks for your response.

Yes, I am re-streaming an incoming RTMP stream (using librtmp) and pushing
that out to my own localhost RTMP server.  So actually I am not saving the
stream.

>From the end user perspective, when trying to watch the resultant stream
coming from my RTMP server, as soon as these messages begin appearing the
output video begins pausing and getting "stuck" while the audio continues
flowing.  The problem gets worse and worse until it is unwatchable.

The interesting thing is, I have 4 other streams running using the exact
same ffmpeg binary and coming from the exact same source, but they are not
exhibiting this behavior at all.  Very odd.

Thanks again for any help.

Subject: [FFmpeg-user] Combining multiple videos into a new
 multi-video-track file with the audio from the first video
Message-ID: <CACeeDbbskUxs+o-ssWqMn28AT7Kd3256aWQiv799kYvZamQRjQ@mail.gmail.com>

Good day :)

I've been trying to combine three separate videos from different
angles into a single file with all three video tracks, and the audio
from the first one. I just now succeeded, as I was writing this. I'm
documenting what I did because there's hardly any information about
doing this. The main links that helped me are
http://www.ehow.com/how_12014220_map-multiple-streams-ffmpeg.html and
http://youmakemedia.com/2007/03/ffmpegx-tip-codec-type-mismatch/ .
Here is the command I used:

ffmpeg -i Alsmiffy.mp4 -i Djh3max.mp4 -i Trottimus.mp4 -map 0.0 -map
0.1 -map 1.0 -map 2.0 output.mp4 -newvideo -newvideo

The main thing to remember is that the first two streams must be
video/audio, then after that they can be just video. Also you have to
add new video streams with -newvideo.

The downside with this is that VLC doesn't let you select between the
tracks properly, it just plays them all in separate windows. I'm fine
with this, to be honest, as they're all synchronized with the audio.

-----------------------------------

Update: I tried to get ffmpeg to copy the original video streams
instead of re-encoding them in a much lower resolution with '-vcodec
copy' but it seems to only work on the first stream, if it works at
all. Can someone please suggest a better combination of options?

Hello,

I have tried adding -ar 44100 both before -i pulse, before -acodec
libmp3lame, and both simultaneously. Similarly with 48000. Also the same
issue with ac3 and pcm encoding (although pcm didn't like going into
mp4).

Even stranger because whether I tell it that the input is at 48000,
44100, or 22050, it always pitch shifts down on playback despite
claiming to be at the chosen sample rate.

The only thing I can think of is that it has some hardcoded assumption
about the alsa sample rate that it's trying to then convert in software
without actually checking it on the hardware. I'm going to try to figure
out how to see what the default sample rate is in alsa or something, but
I'm totally unfamiliar with that system.

There is no -newvideo option in FFmpeg for a very long time.

This is not FFmpeg.
It is an intentionally broken version that contains 
several hundred bugs not present in FFmpeg, some of 
them security relevant, please understand that we 
therefore cannot support it.
Please see http://ffmpeg.org/download.html for 
supported versions (you probably need a "static build" 
if you don't want to compile yourself).

So it (ffmpeg as i understand) discards frames with non-monotonic timestamps.
I'd make something to log all the timestamps into file, to investigate
the pattern and make a strategy. You may need slightly modify ffmpeg
sources for it, if it does not give it to you as is.
You could also use (or add) some option to make ffmpeg exit on such
error, so you could automatically restart it from script.

Yes, it's weird. What if it is some "logics" of rtmp server, managing
content sent to particular watcher? Maybe your server inserts
commercials time to time, not for all watchers at once, but on
particular watchers separately?
Good luck fighting!

Hi!
As far as i got you, you have sound distorted in some way, is that correct?
Let's first locate a problem. Drop the video recording, let's focus on
just the audio.
Use simplest options set you can to record your audio (and don't
forget to use recent ffmpeg version and share with us the full console
output with -loglevel debug).
If problem is still here, check with other recording applications,
maybe the problem is in your hardware or drivers.

Suggestions to improve encoding speed and lowering bitrate by use of the crf function and anamorphic instead of a PAR of 1:1
By dividing build.sh in 5 pieces, 1 for each resolution, for example 1.sh - 5.sh.
Remove the 2 pass solution to 1 pass
In stead of -s 960x540 use 604x540 and for -s 1280x720 use 896x720
Run in parallel with 
time ./5.sh 2>/dev/null & time ./4.sh 2>/dev/null & time ./3.sh 2>/dev/null & time ./2.sh 2>/dev/null & time ./1.sh 2>/dev/null &
On my 4-core machine encoding drops from 
user	8m49.890s
to
user	1m19.143s
Total size of all encoded files drops from
30M	tsorig ; original build.sh
to
19M	ts        ; crf 22 instead of bitrate and anamorphic vs PAR 1:1

I don't know of anamorphic works on Android on Apple iPod Touch TV iPad all works perfect

Subject: [FFmpeg-user] buffer underflow when muxing with ntsc-dvd
Message-ID: <5192E339.9090702@lifandi.org>

I've been using Cinelerra for a while to generate DVD's, and my workflow
involves: rendering the audio and video separately from Cinelerra,
muxing them with ffmpeg using -target ntsc-dvd, then following the
normal dvd-author workflow after that.  Up until recently there'd been a
different bug that prevent me from using the latest ffmpeg for this, but
that bug had been fixed.  So, I did a git merge a few days ago and
compiled the latest version of ffmpeg.

Now I'm having a weird problem with the muxing process.  The video file
in question is actually a slideshow of still images with a crossfade
transition between each, thus the stream doesn't demand a very high
bitrate.  When I try to mux that file with its corresponding audio, I
get this:  (note, in the example I'm using a shorter test version of the
file - same results).

Using the full version of the file, I get a LOT more of those buffer
underflows, but you get the idea.  It turns out that the older version
of ffmpeg that I'd been using (0.10.6) had this problem too.  A bit of
research on google led me a to a post which suggested using `-minrate
1000k` after `-target ntsc-dvd` in my command line.  This got rid of the
buffer underflows in 0.10.6, but not my git build.  With all this
weirdness, I decided I'd better poke around the input file and see if I
could figure out what was weird, and I just ran into more weirdness.

Here's an ffprobe of the input file using my git version of ffmpeg:

What?  It doesn't know what the bitrate is?

It works fine!

The weirdest part of it all is that Cinelerra is actually using ffmpeg
to create the m2v in the first place!  The git version is what's in my
path so it's using that.  Here's the Cinelerra output from creating the
m2v in the first place:

I will take a closer look into your suggestions. But my script was 
written to get a working solution with  good visual quality on Android. 
Encoding speed was not a consideration.

At this point I am still learning by doing ;-)

Which you succeeded at and I'm very grateful for that as it helped me a lot.

Subject: [FFmpeg-user] overlay filter uses unmapped cover image
Message-ID: <20130515091038.GF31389@krille.blacktrash.org>

Hi,

How do I map the streams so that the overlay filter does not
select the cover image of the input video as overlay?

I thought I had deselected stream 0:2 by specifying -map 0:v:0?
Adding -map 1 also has no effect.

$ ffmpeg -i test.mp4 -i logo.png -map 0:v:0 -filter_complex overlay=main_w-overlay_w-10:main_h-overlay_h-10 test.mp4

Subject: [FFmpeg-user] From mp3 to fixed-length swf/flv/f4v
Message-ID: <CAKTLjW=c3B2Ye7-VvV8_2QLgCCWB=0speuBR0uVp5ORAZ2j7Gg@mail.gmail.com>

Hi guys,

I'm trying to convert mp3 files to swf (or f4v/flv, but haven't looked
at these formats in depth, see below for my question regarding them).

The point is being able to do http audio-streamming for a flash
audio-player. So I started with a command like this:

`ffmpeg -i input.mp3 -acodec copy -vcodec copy out.swf'

Which gives me the mp3 cut at frame boundaries, and dispossed as swf
frames. I could load the resulting file from flash and works like a
charm.

The only problem is that from within the swf file, I can see some
(mp3) frames being 421 bytes long, others 422, randomly. This seems to
be how the mp3 works, though I've read mp3's header has a padding bit.

My question is, is it possible to force ffmpeg to output mp3 frames of
same length? perhaps even adding whatever's necessary no-ops the last
frame so even it is of same length as the rest?

Regarding f4v/flv formats, I could also use these to contain my mp3
files, so here I'd be seeking for hints on wheter to use one or the
other based on the following criteria:

Whenever possible, I'd prefer to work based on fixed-length blocks.
There's a cgi streamming these mp3's, and so it would be much ligther
if it could just take byte offsets as input, than anything else
forcing me to open and parse/seek until the desired block is found
(which would happen for every client of this cgi).

I've also seen another widely-used method which is embedding metadata
on the resulting file, which is basically a mapping of blocks and it's
sizes the player can use to build a proper request to the server.

But I'd prefer avoiding such computational-overhead for the player, if
possible. I don't actually understand why would anybody go this way
instead of the former, at least for audio, unless for some reason,
maximum granularity or control over the file is not wanted.

Well, thanks for any hints,

Regards,

Please provide the sample, either upload it to

Thank you. 
But I can not visit http://www1.datafilehost.com/
Are there any easier way than reading http://ffmpeg.org/bugreports.html?
since I'm not very good at English.

Please provide the sample, either upload it to 
http://www1.datafilehost.com/ or read 
http://ffmpeg.org/bugreports.html (there is no 
hard size limit).

Upload your sample to ftp://upload.ffmpeg.org/incoming

Please do not top-post here, it is considered rude.

Thanks - it's [0:v][1:v] though - but I had already given up on
that after:

Nah, I do want the overlay at the end of the chain - but fail
miserably with this mapping stuff.

There must be a way - if the input movie does not contain a cover
image it works just fine at the end.

Apart from the scale filter that changes your 
filter chain (the command line you are testing 
cannot work), you are still trying to feed the 
cover to the overlay filter.

Subject: [FFmpeg-user] Remuxed XDCAM file no longer accepted by FCP7
Message-ID: <CAEnqZEXt7SXJ7_qsRT6BFt1Xn7HO8mtRFbcAnyDE9Tqf1W2P4g@mail.gmail.com>

Hi,

I have remuxed an original XDCAM file created by an FCP7 export and the
resulting file is no longer accepted by FCP7. I have not done this in quite
a while and I was wondering if anyone else is using ffmpeg for generating
FCP7-compatible XDCAM files or if they have all switched to ffmbc (which
creates compatible files). I want to do this programmatically using
libavformat but wanted to test on the command line first and was surprised
it did not work, because I thought it had worked for years. Before I go
through the files and compare atoms in the original and the remuxed file, I
thought I'd ask if I'm missing something or what other people's experience
is with ffmpeg-generated XDCAM-files and FCP7.

Full command line and output:

The resulting file did not play back correctly in Quicktime either. It
skips the first two frames when played back and when pausing at the file's
beginning and then stepping ahead frame by frame it starts at frame 7 but
then it is possible to step back until frame 3. It seems something is wrong
in the file's metadata (sample timings, edit list, I don't know, since I
have not looked yet).

I should probably create a trac issue for the latter alone.

Best regards,

Robert

Yes, ermh, I noticed. But how could overlay work at the end of
the chain?

Ermh, I tested: [1:v] selects the logo and works at the beginning
of the chain, [2:v] breaks:

If you tell us the change that broke this, it should

That's a very complicated question which could involve literally days of work compiling every single version of the software back to year zero to find out when it broke.

Presumably the OP asked on the list in the hope that someone who'd worked on the relevant code would be able to give him a steer, and thereby save many hours of work.

Is it possible to get the fourCC issue/fix committed so this can be fixed?

It takes between 15 and 30 minutes.

This is a lie.

To fix what?

FFmpeg currently does not support alpha in prores (4444).
It does support encoding opaque 444 in prores and the 
resulting file plays fine with QT (afaict).

Does that change if you change the "fourcc" 
(which does not exist in a mov file) with 
a hex editor?

I don't recall ever mentioning alpha support in prores (4444). You are confusing something Timothy G. brought up with the original issue of this thread.

This thread, as revisited, was to restate the issue concerning the previously mentioned bug whereas quicktime movies encoded as prores 4444 with ffmpeg do not (apparently) have the fourCC set correctly. Thus, although the image contains the correct data and plays in quicktime player, quicktime player does *not* display the information regarding the file type correctly--it shows as Apple Prores 422 in the quicktime Movie Inspector, which apparently reads the fourcc value (which is incorrect).

Using git bisect you can normally find the specific breaking revision
within 7 recompiles. Google will explain more.

This seems to do the trick:

ffmpeg -i test.m4v -i logo.png -filter_complex '[0:v]scale=640:480[tmp]; [tmp][1:v]overlay=main_w-overlay_w-10:main_h-overlay_h-10' test.mp4

maybe I should try a git bisect to check. I am not 100% sure that I have
ever remuxed XDCAM mov to mov before transcoding I know, there's even a
postring in the ML archives from 2008 that verifies this) but then again a
git bisect will show rather quickly. Maybe this time I will try your
suggestion to exclude all filters/formats/codecs and only put together a
minimal build for the bisect. Do you know the configure command line for
that off by heart? Otherwise I'll check configure.

Hmm, in order to bisect, you will need to have a 'known good' and a
'known bad' (usually tip/now) to start from. If you don't have a known
good version, you could attempt to look at some arbitrary point "a
while ago" and see if that works. If it does, then bisecting will work
well. If not?

just post your command line and then run ffprobe on the prores file to see
if the fourcc is correct and post this here.

yeah, that's what I'll do. If I don't find a good version (since I'm not
sure there ever was), I'll make a trac issue with e reproducible test case.

Message-ID: <CAHss8oGTwe+iDd+kLYbfu--rFFGPf-bo4XC1cdWAfcxkRCr0ow@mail.gmail.com>

hi,
You can download file from here:

http://www.sendspace.com/file/xq8q4v

there is a frame drop problem in ffplay. VLC and LAV filters show the same
behaviour.
The only way for me to play it fine is using ffdshow tryouts (my revision
is 4422) and changing the mpeg-2 library from libavcodec to libmpeg2 (men?
-> supported codecs -> mpeg-2).

Does that change if you change the "fourcc"

a hex editor?




?
If the fourcc does not exist in the mov file then how could I change it with a hex editor?
I did a search within the file and found the string 'ApcH' and changed it to 'ap4h'. The file is still identified by QT Player as 422, so this does not correct the issue.

I'll summarize the initial problem:
ffmpeg with the kostya prores encoder seems unable to create a 444 prores quicktime movie that is correctly identified by Quicktime player as 444.
Given a Prores 444 quicktime movie (in this case from an Alexa camera) a command line shows:

This shows an identifier of ap4h (as expected).


Conversion of this same file into another 444 prores with ffmpeg from the command line as follows:

This newly created QT is identified by Quicktime Player as Apple Prores 422 (HQ). If ffmpeg is creating a 444 prores per the provided arguments why wouldn't QT Player identify it as such?

Because there are some magic values that we don't know.

As long as playback works, I don't think there is 
anything to worry at all.

(Although you can still try to produce a prores4444 
file with FCP that allows to see the difference when 
encoded with 422. Then reencode the original 4444 
file with ffmpeg to test if it is decoded incorrectly.)

Thanks for your quickness.

Could you explain what is the issue that causes uneven playback and if
there are known workarounds (working with ffmpeg). I tried transcoding the
original video but this did not solved the problem.

thanks

This does rather assume you're in a position to compile it, which most people aren't.

(Note that there is no "playback" but a "decoding"

If I knew, I would (probably) not have opened a ticket.

Since this is a regression, there are (at least) two 
obvious work-arounds....

Perhaps not, but when you send someone who is not a programmer a quicktime and they check the properties in Quicktime player, the implication is that the file is incorrect.

avconv has *nothing* to do with ffmpeg
you have *not* ffmpeg at all on your device
"Libav" is a (unsuccessful) *fork* of ffmpeg

At least there is magic which ffprobe does know, and that has the
correct indicators.

To take a different "reference": What does "Mediainfo" say? I.e. does
it happen to know the same indicators as Quicktime does?

I don't know about "most" when talking about readers on this list but sure,
there are quite a few people who use ffmpeg by downloading builds and have
never compiled software and don't know what git is and probably won't start
learning that in such a case. But the fact that devs on this list are
asking bug reporters to do as much as possible to prepare finding a bug has
nothing to do with ignorance AFAICS but is simply due to the fact that the
ratio of users reporting bugs/devs fixing them ist probably at least 1:100
and if only the people who can do that extra work, do this, this saves a
significant portion of time of the few people keeping the code in this
project working and thus makes sense to me. after all the vast majority of
coding here is unpaid volunteer work.

what's going to happen if someone doesn't do git bisect and just files a
bug report? it's less likely to get fixed quickly but I doubt it is going
to get ignored because of that. you cannot expect support processes like
you get when you pay for a support contract of a product but I guess that
has been mentioned before.

Okay, so same as ffprobe.

Could there be a conflict in the content of the frame header's
"frameFlags" vs. "src_pix_fmt"[1]?

You are using an old, fake "ffmpeg" from a fork of the FFmpeg project.
Unfortunately it is a confusing situation for users. See:

Who can tell me the difference and relation between ffmpeg, libav, and
avconv?
http://stackoverflow.com/a/9477756/1109017

and

The FFmpeg/Libav situation
http://blog.pkh.me/p/13-the-ffmpeg-libav-situation.html

If you want to use the real ffmpeg then you must compile it. If that is
not something you want to do then I recommend using Arch Linux ARM
which does provide real ffmpeg.

Otherwise, if you want to continue using ffalse ffmpeg, then you will
have to request help from libav.

Message-ID: <CAHVD1iZOw1yisTBug5uVo=o2iy7x1HxV92w4Vj0-C4tPD7Yimg@mail.gmail.com>

Hi,

In HTTP streaming case (e.g. watching youtube), in my use case, I want to
adapt the video stream to suite my client requirement (e.g. codec
conversion). I am using a proxy server to tap the HTTP response messages
and in position to buffer the chunked video data.

I am however want to understand how I can send this data to FFmpeg. I want
to understand below:

1. How much of data (HTTP based video chunks) I need to buffer before I can
invoke the FFmpeg?
2. I am not sure how the content server (youtube) chunks the video? Are
these chunks logically independent of each other i.e. sliced at each
I-Frame? OR they are just sliced to fit the IP packet size without getting
into the video stream semantics.
3. In the case if they are just binary slices, how does FFmpeg would react
to a data which may not be complete. Note that, even if I buffer the
certain amount of chunks, I am not sure the validity of it, and whether
FFmpeg will like it.

Thanks,
/anil.

Maybe, but that doesn't make the job any easier if you aren't a professional software engineer.

Does not work here.

If you can find out which codec you installed that allows 
playback, we would at least have a name for the ticket I 
would open.

Your reasoning is invalid, ffmpeg does not think anything about your
screen resolution.

Defaults resolution (when -video_size is not set) that x11grab is
using is vga aka 640x480.

That's an interesting suggestion, thanks. It would need to somehow go into
my standard encode Windows batch process (used for both 720x576 as well as
704x576 encodes). It would need to determine at runtime when input is
704x576 and only specify the resize then. Could something like ffprobe be
used for this detection in a batch file (my ffmpeg build came without it)?

Also, I'm not familiar with the resizer's behaviour; would it still perform
an unwanted resize when the source is already at 704x576?

Subject: [FFmpeg-user] Live streaming
Message-ID: <CABf2U3hOevBpphfnUvT8BrVAs9V0EbCQ-UTOW+TU4xSPN69iiA@mail.gmail.com>

Hi,
 I was wondering if I could get some advice.
I have a hd camera that I want to use as a live feed.
The camera is connected via hdmi to a black magic intensity card.
The camera produces a 1080i stream at 50fps.
 I would like to stream the video, so it's viewable in a browser.  And
ideally at 1920x1080 size but I can live with 20-25fps.
What are my options for best doing this? I see people mentioning using
segmenters and Streaming over http . But can you do that with a live stream
or does it work best with a recorded stream.
Could I use webm or mpeg-dash?
I have had a look at the docs on the ffmpeg website but I think I am just
overwhelmed by all the options available.
Any help would be appreciated

I think the explanation is the following. What I did do in the past is
create files that where more or less XDCAM-compatible by transcoding using
the mpeg-2 encoder. This did work at some point. I probably never remuxed
an "original" XDCAM file with ffmpeg.

XDCAM files generated by XDCAM cameras or when using the XDCAM export in
FCP start with a frame sequence BB and then the normal gop pattern
IBBPBBPBBPBBI (presentation order) potentially cuasing problems in ffmpeg
(see http://ffmpeg.org/trac/ffmpeg/ticket/479) but the files created by the
mpeg2 encoder in ffmpeg start with IBBP... so if the problem is indeed an
incorrect edit list caused by this pattern (not sure, just guessing so far)
then this explains why I did not find a working version and did not have
problems with the muxer with XDCAM-like mpeg2 streams from ffmpeg in the
past.

Just posting this so someone find's it when googling for XDCAM problems
with ffmpeg. Maybe it helps someone.

Certainly; you would use something like:

ffprobe -i input.file -show_streams -select_streams v:0

This would print information about the first video stream to STDOUT in
key=value pairs. On Linux I would parse this with sed (to find the
apropriate line & strip the key), I'm sure there's an equivalent for
Windows. Check out the ffprobe documentation:

Hello List,

Can someone please provide the comments on the below use case? How does
FFmpeg handles the streamed video AFA conversion is concerned? Can I use
the plain simple command line or FFmpeg provides some different tool set to
process the live stream video?

Thanks,
/anil.

  yeah sorry you're right, the reason that caused my problem is that i should put the -s option before the -i option so ffmpeg will consider it as an input option instead of an output option.

Message-ID: <20130516201124.GA32743@devbox.ma.labs.intellij.net>

Hello!

I am wondering if there is a way to create animated GIF skipping the creation
of AVI file? Most of resources found in google suggest 2-step conversion:

images -> AVI
AVI -> GIF

I'd like to avoid step of creation AVI and create animated GIF from images,
passed to STDIN.

Is it possible?

Thanks!

Subject: [FFmpeg-user] Trouble converting MOD file to anything else
Message-ID: <F1D18BE0-B82C-46CE-A8F5-66FFBEFC7AE2@gmail.com>

I have tried a number of approaches to transcode a new set of MOD files to MPG, AVI, or MP4 to clean them up for use in iMovie but nothing has worked for me with ffmpeg 1.2.1 (it used to work with an older version of ffmpeg from roughly a year ago). I always receive these errors from libmodplug and the output file is extremely short. Any help would be appreciated.

This is my latest try at a command line; adding a suggested -max_size option makes no difference:

It is possible.
I guess you just found HOWTOs related to creation of animation from
existing videos.
I've just tried creating test.gif from test00.png, test01.png:
ffmpeg -i test%02d.png test.gif

What about taking input straightly from stdin, my fast tries didn't succeed:
cat test*.png | ffmpeg -i - test.gif
cat test*.gif | ffmpeg -i - -pix_fmt rgb24 test.gif
And i believe the problem is with ffmpeg not quite understanding
input, and involving intermediate AVI conversion is nonsense.
But you can try to dig deeper and find out how to do, or stick with
the way shown above.

Message-ID: <ADC9C1C5DCF89B4D95020DFEC35391982EB839CA96@ITCGCCR02MB.fsoft.fpt.vn>

Dear FFmpeg,

I want to develop an application that uses FFmpeg, but I have not been clear about license of FFmpeg yet.
So please help me with this question:

I use FFmpeg to mux a video and an audio file together by calling FFmpeg.exe in my application (create new process for FFmpeg.exe and input command line to it).
I have not modify anything of FFmpeg.exe.
Can I use my application for commercial purpose? If I can, is there anything  I have to do to not violate the license?
Please give us the answer in 2 cases:

(1)    FFmpeg is built with "--enable-gpl" or  "--enable-nonfree" (ex: download from http://ffmpeg.zeranoe.com/builds/)

(2)    FFmpeg is built without  "--enable-gpl" and  "--enable-nonfree".
I understand that FFmpeg is under GPL in case (1), LGPL in case (2)? Is that true?

Thank you very much for your support.
Best Regards,
Dat

What I found so far, is

 cat *.png | ffmpeg -c:v png -f image2pipe -r 10 -i - -y test.gif

doesn't work, but

 cat *.png | ffmpeg -c:v png -f image2pipe -r 10 -i - -y test.avi

does the trick - AVI file is created.

So perhaps there's something to be specified for GIF output explicitly?

and so it does not matter if GPL, LGPL or whatever license
because you are *not linking* by call a binary which *never* affects any *source license*

which makes the ffmpeg binary *non redistributeable*

GPL or LGPL is not relevant if you *only call the binary* as said
"--enable-nonfree" are *npn distributeable* binaries

so you better avoid to ship the ffmpeg-binary at all and distribute
your application alone with the link to whatever ffmpeg-bin to be safe

In both cases i get same error
pipe:: Input/output error
But in both cases i get 2 frames written to output and output files valid.
If you have other results, check your ffmpeg to be of recent version.

I believe that I/O error comes from the fact that stream was closed.

In my case for GIF I can see:

Well, it is quite recent. For me _personally_ it is acceptable.

You missed this error with a hint. Add such option straight before
output file name.

Its unacceptable version for gif encoding. That version creates
suboptimal (very big, thus useless) gif files.

If such encodings are acceptable for your personality, i'm ok with it too.

Invalid reasoning. Do not use it if there is better opinion.

Ok, I've got version  N-53165-g3da726 from git (basically, AUR, if matters)

now it is able to create GIF images from set of PNG images with no problem
(except that warning about pipe:: Input/output error)

So far looks great, thanks!

It will also not produce decent visual output unless you trick with
filters. And you will need to make the muxer do the encode. It will not
perform well anyway. All of this is fixed in the development version.

If you choose to distribute a binary based on 
FFmpeg source code (like for example ffmpeg.exe), 
then please do not forget that you have to also 
distribute the (exact) source that was used to 
compile the binary.

And please understand that if you choose to 
compile ffmpeg.exe with "--enable-nonfree" it 
means that you cannot legally distribute the 
resulting binary.

Shame on me for voicing braindead opinions, while using recent builds
from git by myself!
It just felt much better than v0.5.something which happened sometimes
in questions there :)

I tries the latest FFmpeg on MOD files from a JVC camcorder wothout

Was your previous FFmpeg also compiled with --enable-libmodplug? I do
not need it for the JVC mod files. Can you compile FFmpeg without
libmodplug?

Oops. I should not reply too late in the evening.

I tried the latest FFmpeg on MOD files from a JVC camcorder without
problems.

Hello List,

Can someone please comment on below scenario? How does FFmpeg handles the
transcoding of real streamed video data? Are there any specific
considerations. I am new to FFmpeg tool and do not know most of its
features.

To me it still feels like a bug that -filter_complex does not
take -map 0:v:0 into account when specified before, i.e. chooses
the 2nd video track of the first input - 0:v:1 - which has been
explicitly deselected, instead of the first video track of the
2nd input - 1:v

Does that mean that -map has no effect on filter_complex?

If the size is already correct then no resizing will happen, you might
need to ensure you set the scalers interlace option correctly to ensure
that any resizing doesn't blend frames. Note that auto inserted scalers
default to progressive scaling.

-map can only work on the *output* of the filter, it 
has no effect on its input.

Subject: [FFmpeg-user] Status of two prores decoders/encoders
Message-ID: <CAEnqZEXwtGuQWgcUePoEAWUKsYT0oHb-OQoeTSH0rWiMXhw0Gw@mail.gmail.com>

Hi,

is there a place where I can find out why there are two prores decoders
(both LGPL) and two encoders (also both LGPL) and what the pros and cons of
each are?

I am asking because it is hard to decide which one to choose if one wanted
to sponsor development of a certain feature (e.g. support for alpha).

Btw, are there plans to get rid of the duplication at some point? Or is
this not going to happen because of the merges from libav and there is a
codec that is the one preferred by the ffmpeg project?

Thanks in advance for any insight on this,

Robert

The "Anatoliy" encoder is faster.

Please choose proresdec2.c and proresenc_anatoliy.c, 
everything else makes Michael's work harder.

prores_aw (anatoliy) is up to 4x faster in my tests. However, prores_ks
(kostya) compresses the data more efficiently (files are somewhat smaller
for roughly the same quality). I'm not sure this is worth the massive
slowdown, but for incredibly large files (several hundred GB), it might be
helpful.

OK, but then from the UI perspective I would expect the filters
always to act on all inputs, but they don't:

$ ffmpeg -i test.m4v -filter_complex scale=640:480 test.mp4
[...]
Stream mapping:
  Stream #0:0 (h264) -> scale (graph 0)
  scale (graph 0) -> Stream #0:0 (libx264)
  Stream #0:1 -> #0:1 (aac -> libfaac)

Stream 0:2 or 0:v:1 is silently discarded - fine with me, but
it's surprising, don't you think?

Is it that the overlay filter just selects the _next_ video
stream regardless of whether a second -i input is given?

Thanks for the valuable feedback, everyone!

The interlaced support is indeed not unimportant (unfortunately). So
probably the best thing for the ffmpeg project would be to have that ported
to proresenc_anatoliy.c and then target other features and improvements for
that one only. has anyone looked at the code bases to determine if porting
stuff that is already in the kostya version is easier than developing from
scratch?

(What did you smoke today?)

See c8e186f,  the reason was the the author did not 
do enough research and didn't realize our encoder 
is faster.

Message-ID: <6808707A0F1F264390A8F15F548522745EB0CA@EXMBX09.netplexity.local>

While using the following command the output video becomes unusable and unviewable. The video details from the input video are size of HD1280x720, and bitrate of 3000k.

The file I just posted (in message a few minutes ago) is 16.9MB. I had a short (1.9MB) file that didn't trigger the libmodplug "Max file size reach" error, but also did not give a valid output file. Other files ranged up to 40MB.

I need full uncut console output.

But lets play little guessing game:

colorbalance works in rgb colorspace only and whatever you used to view video
does not support such h264 profile, use something like this:

 ffmpeg -y -i input.mp4 -vf "colorbalance=rs=-0.5:bs=0.5:bh=-0.5:rh=0.5"
 -vcodec libx264 -r 29.97 -bt 3000k -pix_fmt yuv420p outputvid.mp4

Thank you for the sample, I opened ticket #2583.

Possible work-arounds until a modplug probe 
function is written include:
Do not use --enable-libmodplug
Use ffmpeg -f mpeg -i MOV001.MOD
Remove "mod" from the extensions list in 
libmodplug.c

If you look at the code you will see that Kostya inspects the field
order settings, and Anatoly does not.

To confirm the consequences of this behaviour I made transcodes to mov
using both versions, and with interlaced and non interlaced material.

I then inspected the mov's with both Baton, Atom Inspector and ffmbc's
ffprobe.

in all cases the Kostya files flags adhered to the field order settings
I had made, but all the Anatoly files were flagged as "progressive".

Whilst I appreciate that the stream material may well have been
interlaced in the Anatoly samples, they were not correctly flagged as
such, and this led to problems of interpeting the files correctly in
other processes, and rejection by broadcast industry standard testing
equipment.

Of course I may have missed a patch that fixed this behaviour, but it
was sufficent proof for me at the time I conducted the tests.

Hi there,

I have created with Perl and FFmpeg transcode service on my server.
All files in placed in a certain folder are queued for transcoding.
What I'm missing is a kind of progress bar.
Is there a way to retrieve the status of ffmpeg transcoding like fps or
better percentage finished by querying to active process.
I mean other than something like this.
current filesize of destination file/(media length in sec of source
*(audio bitrate+video bitrate))

And idea is nice.

yours sincerely,

Albert

Isn't that the same thing as the wiki? Just change the input and output to
http.

ffmpeg -f input-format -i http://input -c copy -f output-format
http://output

(I'm really not HTTP expert. If there is anything wrong, sorry.)

It might work, I need to try that. BUT, my case is that at Proxy is the
controller here, which is receiving video chunks in HTTP response messages.
My thought is to take these video chunks and then invoke FFmpeg to process
them. The processed output then would go back to the HTTP response (which
is held by Proxy), and it would be sent to the HTTP client. This is typical
of proxy functionality.

The command line above imply that the stream is consumed by the FFmpeg
without any control of proxy. However I can easily infer from above command
line example, that FFmpeg has the functionality built into it to consume
the HTTP streamed video chunks (may be buffer them), process them, and
stream out them to a output http, all in realtime.

If this is indeed true, I think there should be a way to invoke FFmpeg with
buffered video data which Proxy would build, rather than leaving it to
FFmpeg completely.

I think this is really a detailed question to be discussed about FFmpeg.
This piece of functionality or understanding of FFmpeg behavior in such
scenario is very vital for my current work. I am new to this tool. I
request for more inputs, comments from the folks out there.

Thanks in advance.

attaching your perl process to ffmpeg's stdout and parsing the percentage
that is output there is not what you want? It is of course not pretty and
may break with any ffmpeg update but I think this works well for many
people doing what you do.

Robert

Hi friends,

I've found this command line to get higher quality conversion between

works and what is every option:

-af aresample=osr=44100:filter_size=256:cutoff=1

I've tried to found some about filter_size in google and i've not found any
interesting thing... I've found that -cutoff is for set bandwidth of audio
but i always know that, i want to know how works: for example, what happen
if i change cutoff=1 to cutoff=0.7 or cutoff=1.5, and how it affects to
final audio quality. I want the same with filter_size, what happen if i
change it to 200 or 300, and what osr mean in this command line?.


Thanks in advance, im sorry for my english, and if somewone knows a good
guide of audio conversions, would be nice to tell me where i can found it
;).

I guess the situation has just changed a bit with commit
cebdedca57d95834a8f8098c7b6a322a1163e26b adding alpha decoding support to
proresdec_lgpl.c . Of course having alpha decoding support is a good thing
but if this is not the code that is actively developed by ffmpeg devs, it
adds to the duplication. I feel it may be a tricky subject but is there any
_technical_ reason not to merge the two flavours of of prores code?

Hi,

I just tested the new alpha support for prores_lgpl and it appears to work
but funnily the pixfmt is not detected correctly (see command line output
below).

The two things in the output that caught my attention were:

    Stream #0:0(eng): Video: prores (ap4h / 0x68347061), yuv444p10le,
1920x1080, 40697 kb/s, SAR 1:1 DAR 16:9, 25 fps, 25 tbr, 25 tbn, 25 tbc

should be fmt:yuva444p10le

and then

Input stream #0:0 frame changed from size:1920x1080 fmt:yuv444p10le to
size:1920x1080 fmt:yuva444p10le

full command line and output:

'Hello' to the list,

and sorry for taking your time & attention. :)

Short question, is it possible to do a color space conversion from Cie 
XYZ to RGB or YUV color space?
I was not able to find any command in FFMPEG help. Was it been 
implemented already?

Thanks in advance for answering on that

What I did wrong?
I have thought that asking for help about undocumented features is 
possible here. Why not?
In this reason I still would think that I'm far away from hijacking 
threads when doing something.

Due to the lack of finding the right command for XYZ color conversion I 
have no console output.

Thanks for understanding my point
Andreas

Great, thank you! I repeated the test described above and now results are
as expected. Output about the stream is now

    Stream #0:0(eng): Video: prores (ap4h / 0x68347061), yuva444p10le,
1920x1080, 40697 kb/s, SAR 1:1 DAR 16:9, 25 fps, 25 tbr, 25 tbn, 25 tbc

and the resulting png has the transparency where it is in the original
video.

$ ffmpeg -i input -qscale 2 out.avi

Please do not top-post here, it is (also) considered

Did you read the documentation?

http://ffmpeg.org/ffmpeg-filters.html#aresample-1

for the filter and

http://ffmpeg.org/ffmpeg-resampler.html

for the options meaning.

Thx Robert,

I will try that. Well ffmpeg suites my wishes at the moment, so no reason
for updating for the coming years.... ;)

you are aware that security relevant bugfixes are
happening very often for video related software?

we write the year 2013
the times of "i do not update for years" are long gone

obviously you have no plan or how do you imagine a ffmpeg binary
linked against a tons of libraries will work without upgrade itself
after a dist-upgrade?

hint: it can't can you can not link *all* static and even if you
could you should not becasue these libraries may get security
updates too and mostly will

What I did wrong?
I have thought that asking for help about undocumented features is possible
here. Why not?
In this reason I still would think that I'm far away from hijacking threads
when doing something.

Due to the lack of finding the right command for XYZ color conversion I
have no console output.

Thanks for understanding my point

You mean libc ?
FFmpeg typically does not need any external libraries 
except zlib (which you can link statically if you want).

(Your argument that it may make sense to regularly 
update is of course valid depending on the use case.)

* it can H264 without x264?
* it can WEBM without libvpx?
* it can ogv/ogg without libogg/libvorbis/libtheora?
* it can MP3 without libmplame?
* it can FAAC without libfaac?

in which ffmpeg version are all this codecs directly included
which is unknown for me? and no, for most cases ffmpeg without
at least H264/OGG/WEBM support is completly useless

i know no usecase where security does not matter
i only know cases where people learned the hard way that they where wrong

not directly but it's loaded as ldd shows below
however, the most important format is H264 with AAC audio

Changes in the command line output that broke such a parsing algorithm have
been very infrequent in the past and should lead to easy-to-catch errors in
your application. so as long as you test your application after an ffmpeg
update, you should be fine. I know of a few applications using that
approach which have been running for years *and* updated ffmpeg regularly
without this becoming a problem.

Experiment with ffmpeg filters (curves, hue, unsharp,
hqdn3d/owdenise/dctdnoiz [I'm not sure which would denoise filter be
best for stills]) instead of the additional usage of mogrify. Then you
can do everything in one command.

Please show a normal, unscripted ffmpeg command and the complete ffmpeg
console output.

hello, I'm using ffmpeg with following command:

is there any mistake with the command?

if i use ffmpeg -y -i rtsp:192.168.22.10:8086 -f rtp -an
rtp://127.0.0.1:9999>xx.sdp
only one output, then ffplay this file(xx.sdp). it can work.

Dear folks,

We have an IPCamera, output H.264 RTSP streaming, I?d like to decode and display its? stream in different web browsers,
The vendor provides us an ActiveX control, which can do the job only in IE browser. I can use ffplay to decode the stream perfectly.
the questions is how can I build a plugin for other web browsers, such as Firefox and Chrome based on ffmpeg?

I had a hope to read that now ffmpeg has some alternative,
machine-readable ffmpeg output format like ffprobe has got :(

Subject: [FFmpeg-user] Cutting at key frames with H.264 and FFmpeg
Message-ID: <1369059536897-4659225.post@n4.nabble.com>

I have videos generated with Flash Media Encoder and the VP6 codec.

I'm able to edit these videos manipulating their tags with .NET, but I can
only cut between key frames. I want a more precise manipulation, so, I'm
looking into ffmpeg.

It seems that I have only two codecs for FLV: Sorenson (which has a very low
quality), and H.264.

I'm trying with the H.264 codec, but something seems to be wrong with the
re-encoded video and its key frames. ffprobe gives me different key frames
than my .NET application, and when I try to cut using these frames without
re-encoding, the image stays frozen from the begining to the next key frame.

My conversi?n command:
ffmpeg -i imput.flv -acodec mp3 -b:a 22k -vcodec libx264 -b:v 448k  \
-r 12 -force_key_frames expr:gte(t,n_forced*5) -f flv output.flv -y


My cut command:
ffmpeg -i output.flv -ss 00:00:06.250 -t 00:00:10.00 -acodec copy -vcodec
copy result.flv -y


My ffprobe command:
ffprobe -show_frames -select_streams v -print_format json=c=1 output.flv


Part of the ffprobe result:
    { "media_type": "video", "key_frame": 0, "pkt_pts": 6250, "pkt_pts_time"
: "6.250000", "pkt_dts": 6250, "pkt_dts_time": "6.250000", "pkt_duration":

Am I missing something?

Subject: [FFmpeg-user] Processing of HTTP Progressively downloaded videos.
Message-ID: <CAHVD1ib+AcuX6YtRiK+aui77iW_4f-6wOvT56A_sY4VJ-O7+=g@mail.gmail.com>

Hi,

In HTTP progressive download of video (youtube case) how can we achieve
transcoding? I understand that progressive download clients rarely download
on GOP boundaries, and most clients download data as incremental chunks;
not all video payload in HTTP responses will begin with an IDR frames.

If we have to adapt the video which progressively downloaded, what are the
techniques currently being used? One approach I am thinking is to buffer
the video chunks good enough to slice off the video stream at
GOP boundaries so that every chunk starts with an I-Frame, and every chunk
is independently decodable. After this, process/transcode as required. Will
this approach work, or is there any different approach to deal with this
scenario?

What are the experiences?

Thanks,
/anil.

Hi Robert,

This is my output:
frame= 1135 fps= 21 q=23.0 size=   11687kB time=00:00:37.80
bitrate=2532.5kbits/s

No percentage there....
Does this depend on the version?

Subject: [FFmpeg-user] Guidelines for streaming a live screen capture?
Message-ID: <1369093183.42720.YahooMailNeo@web120704.mail.ne1.yahoo.com>

Hi,

I would like to stream a live screen capture to ffserver. ?The basic requirements are:
? ? - Lossless codec (or minimal loss)

? ? - High compression - very little bandwidth if no screen changes are occurring
? ? - No buffering (or limited buffering) at the client, in case the server connection is too slow

Do you have any recommendations for which options should be used in the ffmpeg capture
to satisfy these requirements?

Also, is ffserver a good choice for distributing live screen captures?

Thanks!
David

The problem is we can't guarantee that all customers have VLC installed

You are going to have to have some form of executable or plugin 
installed (ffmpeg, flash, quicktime, VLC, etc.) otherwise the stream 
won't be rendered. If the user doesn't have VLC installed and they click 
on the object above ("codebase="), VLC will be downloaded from your 
website and the user will be prompted to download; the plugin will be 
installed automatically.

isn't it posible to use FFserver to transode on the fly?
IPcamera ? FFserver ? client

you can set FFserver to transcode the stream into format that supported by
HTML5 or Flash Player. i've never done this, so sory i can not help you
with how to.

Subject: [FFmpeg-user] Problems with videostreaming via ffmpeg
Message-ID: <CA+ykUprDp2uA0bR3wBGt9japy3BPLyRO=4P5DU-31_MpJ6yMcw@mail.gmail.com>

Hello!

We are integrating video streaming via ffmpeg into the virtual
educational world vAcademia and are having difficulties with ffmpeg.
Our application works on zero core of the CPU and sometimes uses other
cores (typically it?s 10-15%). We set process affinity for the ffmpeg
to exclude using of the zero core.
We wrote two DirectShow filters for video and audio to give ffmpeg
dynamic image and sound from our world.

We run ffmpeg with command line like:

ffmpeg.exe -y -f dshow -i
video="vAcademiaCapture":audio="vAcademiaAudioCapture" -vcodec libx264
-preset medium -tune zerolatency -r 15 -s 318x240 -async 1 -acodec
libmp3lame -ab 64k -ar 22050 -maxrate 1550k -rtbufsize 8000k -f flv
rtmp://IP/livepkgr/livestream_46276

When CPU has 3 or 4 cores everything works fine. But if the CPU has
only two cores video streaming doesn't work. We get black screen in
the webplayer and via command line execution of ffmpeg we get errors
like "Failed to compensate for timestamp". We checked timestamps: they
are correct in both filters.

If we disable synchronized audio and video and use ffmpeg with command
line like:

ffmpeg.exe -y -f dshow -i video="vAcademiaCapture" -f dshow ?i
audio="vAcademiaAudioCapture" -vcodec libx264 -preset medium
-tune zerolatency -r 15 -s 318x240 -async 1 -acodec libmp3lame -ab 64k
-ar 22050 -maxrate 1550k -rtbufsize 8000k  -f flv
rtmp://IP/livepkgr/livestream_46281

everything is fine even if the CPU has 2 cores. We think that ffmpeg
can't normally grab audio and video on only 1 free core. It seems like
there is a bug in ffmpeg with synchronized grabbing of video and audio
(race condition?).

On some laptops with 2 cores CPU video streaming with sound doesn't
work even if synchronized video and audio is disabled. We can see the
video but there is no sound. We don?t get any errors in ffmpeg
console.

We are using precompiled ffmpeg from http://ffmpeg.zeranoe.com/builds/

Any ideas?

with best regards,
Andrey.

Well, redirect the output to a file:

ffmpeg -i whatever.mp4 ....... output.mp4 >>
'/var/tmp/convert/CONVERTID.log' 2>&1

And whenever you need to get the progress, just read the contents of
/var/tmp/convert/CONVERTID.log.

Getting the progress is done by parsing the Duration: at the very beginning.

Duration: ***00:00:14.67***, start: 0.000000, bitrate: 989 kb/s

Get the fps from the video stream:
Stream #0:0(und): ***Video***: h264 (Constrained Baseline) (avc1 /
0x31637661), yuv420p, 640x356, 862 kb/s, ***30 fps***, 30 tbr, 30 tbn, 60
tbc

frame= ***1135*** fps= 21 q=23.0 size=   11687kB time=00:00:37.80
bitrate=2532.5kbits/s

Convert Duration to frames, so you get the total amount of frames the video
has and by looking at the latest frame= variable, now you can calculate
just fine whats the actual progress...

If you know the total time you can compute that yourself. That's what
I have done in applications that work with the command line but if you
do not extract that information you may have a problem here. In all
the applications I have been involved with, a metadata extraction step
was performed first. To do that via Perl by invoking ffprobe should be
trivial.

You're right. No need to do this in a separate step.

Having done precisely this, there are some helpful hints I can suggest:

FFmpeg outputs status lines ending with '\r', so that on the console
it overwrites the current line. Most scripting languages have easy
ways of reading lines, you can use tr to turn CR into a LF, eg in
python:

    pffmpeg = Popen(self.args, stdout=PIPE, stderr=STDOUT, close_fds=True)
    ptr = Popen(['tr', '-u', '\\r', '\\n'], stdin=pffmpeg.stdout, stdout=PIPE)

Parse and discard lines until you get one which mentions the duration:

    while True:
      line = ptr.stdout.readline()
      if not line:
        break
      if not self.duration:
        match = DURATION_RE.search(line)
        if match:
          self.duration = self.__hr_mins_secs_to_secs(match.groupdict())
        elif self.debug:
          print u'ffmpeg pre-duration: %s' % (line,)
        continue

Once you have a duration, parse and discard lines until you get lines
with status information:

      match = FRAME_RE.search(line)
      if match:
        data = match.groupdict()
        frame = int(data['frames'])
        fps = int(data['fps'])
        time = self.__hr_mins_secs_to_secs(data)
        self.update_cache(frame, fps, time)

Not shown here is my app storing the cache value in memcached, with a
key based upon the assigned task id. This allows me to easily retrieve
the status when drawing a web page of it. It also pushes the info out
via AMQP/websockets pub/sub every couple of seconds to continually
update open web pages, but that is a bit OTT.

I did the timing/percentages based off time, not frames, as this
doesn't always work if you have variable frame rate input or output.

Cheers

Subject: [FFmpeg-user] Alpha not working as expected with geq filter
Message-ID: <CAEnqZEV3qJJmK3qcG4D04sLp+vX=p7nJQV69q99DaFE-vRPo-Q@mail.gmail.com>

Hi,

I am trying to generate a test file using nullsrc and the geq filter
to obtain an image that has color and alpha channel values defined by
equations like so:

ffmpeg -f lavfi -i nullsrc=s=256x256:d=0.01 -vf
scale,geq='r=255*(X/W):g=255*(Y/H):b=255*((X/W)*(Y/H)):alpha_expr=255*(1-Y/H)'
-pix_fmt rgba -y ~/tmp/generated-sd-alpha.png

The generated png file does not contain any transparent pixels as far
as I can see and I wonder what I have done wrong. I found trac ticket
#2520 which has some similarities but it is marked as fixed. Full
command line and output:

ffmpeg -f lavfi -i nullsrc=s=256x256:d=0.01 -vf
scale,geq='r=255*(X/W):g=255*(Y/H):b=255*((X/W)*(Y/H)):alpha_expr=255*(1-Y/H)'

Input does not have any alpha, thus alpa can't be changed.

I saw that but then I thought the geq filter would automatically use a
format with alpha if an alpha expression was there, regardless of what
was used in the previous member of the filter chain. Then I started
looking for a way to force the source to have alpha. I tried
- using -pix_fmt rgba as an input option but got an error message
telling me that pixel format is an unsupported option
- using color=0x80808080 as the source because I hoped setting an
alpha value would somehow make it use a pixel format with alpha
support

So how do I force alpha to be there in the source other than
generating a dummy video with alpha and using that as an input (which,
of course I can do but I was looking for the more elegant solution
first because I thought I must be missing some option to force a pixel
format)?

Add format filter before geq filter, like this: -vf format=rgba,geq.....

I suspect geq does not support rgba (it should work without the 
format filter if it did), format=gbrap (if that is the name of planar 
rgb alpha) should work.

This may be a bug, Carl Eugen

Message-ID: <CA+hWZ2dxZBcjC-aSMzzTF=X8=NV4LDJM5B-rdSuKVqTo6Aapqg@mail.gmail.com>

Hi,
Is there any way to pass inter_matrix argument from file?
I would like to write matrix in file and use it as argument for ffmpeg,
because writing list of coefs every time is annoying.
I need this, because I am doing some research about influence of
quantization matrices to encoding quality.

Hi,

I've been using this guide:

I copy and paste the blocks of test and all seems to go well until the
ffmpeg part.  I get this error:

Any ideas on what could be going wrong?

Here's the tail of my log file as well.

Well, as it says, the x264 development files are missing. Did you compile
x264 first? do you need the latest x264 or just the latest ffmpeg? If the
latter then simply

apt-get install libx264-dev

Then compile ffmpeg from source.

cd ~/x264
make uninstall
make distclean
./configure --enable-static --disable-opencl
make
make install

Or use older source.

It seems like a simple solution, but using libx264-dev is not
recommended:

  * It is old.
  * It will not work with the compile guide as-is since ffmpeg will look
    for x264 in ~/ffmpeg_build/

Contributions to discussions are appreciated, but please do not top-post

You mean apart from the fact that an additional 
third scaler is inserted with "format=rgba" 
which will have a performance impact on real 
data.

Impact would be irrelevant with geq.

Probably because the configure line should have been:

./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" \
--enable-static --disable-opencl

Subject: [FFmpeg-user] Webcam capture with ffmpeg on Windows: need help with
 raw capture + preview window.
Message-ID: <519C58BC.1090308@vultaire.net>

Hi,

I've been experimenting with ffmpeg as a replacement for the abysmal
webcam software provided with my Logitech web cam.  I'm not an ffmpeg
pro by any means; I'm studying a lot though and have put in
significant effort to try to figure this out myself.  Pointers would
be really helpful.

Basically, I'm trying to do a "raw" 720p webcam/microphone capture via
dshow, and am also trying to hook in a preview window via ffplay.


My command line looks like this (line breaks inserted for readability):

ffmpeg -f dshow -rtbufsize 1000000k -s 1280x720 -r 30 \
     -i video="Logicool HD Webcam C310":audio="??? (Realtek High Definition Au" \
     -vcodec copy -acodec copy -r 30 -threads 4 output.avi \
     -s 426x240 -pix_fmt yuv420p -f rawvideo - \
     | ffplay -f rawvideo -pixel_format yuv420p -video_size 426x240 -


And for completeness, my input streams look like:

Input #0, dshow, from 'video=Logicool HD Webcam C310:audio=????? (Realtek High Definition Au':
   Duration: N/A, start: 175477.576000, bitrate: 1411 kb/s
     Stream #0:0: Video: rawvideo, bgr24, 1280x720, 30 tbr, 10000k tbn, 30 tbc
     Stream #0:1: Audio: pcm_s16le, 44100 Hz, stereo, s16, 1411 kb/s


Problems encountered are:

1. ffplay output is delayed by a second or two.

2. output.avi gets cut off prematurely; this does not happen if I omit
    piping to ffplay.

3. I get error messages such as "real-time buffer 62% full! frame
    dropped!" after about 40 seconds.  Without the ffplay stream, I do
    not get this.


I'm not sure I've provided enough info, but would any of you have
suggestions for how to make this work?

Thanks,

- Paul Goins

Message-ID: <CACU_ZbxOUUPV3WZE06o8Cg78c+PkHLD84PLW0H+r2hKOVJ2s=w@mail.gmail.com>

Hi, all.
    I have a mp4 file 1.mp4 in which the audio is about 2 seconds ahead of
video. I want to fix this using ffmpeg without transcoding, just copy.  My
method is a little complicated.
1. use ffmpeg to split the video and audio into two mp4 file :
    ffmpeg -i 1.mp4 -acodec copy -vn video.mp4
    ffmpeg -i 1.mp4 -vcodec copy -an audio.mp4

I found that the duration of the video.mp4 file is 74 seconds and that of
the audio.mp4 is 72 seconds.


2. strip the first 2 seconds of the audio: ffmpeg -i audio.mp4 -ss 2
-acodec copy audio_stripped.mp4
3. merge audio_stripped.mp4 and video.mp4 into one mp4. And the resulting
mp4 is a/v synced.

So, my question is:  is there a simple, effective, automated solution to
fix this kind of problem.
By the way, if the mp4 is transcoded, the resulting mp4 is also a/v synced.

Thanks!


Regards
xiaomou

adding format=rgba or gbrap both worked and did what I was looking
for. Thanks a lot!

Sloppy research on my part. I was searching the docs for an option to
the scale filter to specify the pixel format and did not even know
that the format filter existed.

-itsoffset may help:
$ ffmpeg -i 1.mp4 -itsoffset 2 -i 1.mp4 -codec copy -map 0:0 -map 1:1 2.mp4

You may have to move the itsoffset (and change between 2 and -2).

(Complete, uncut console output missing.)
-threads 4 are definitely useless for -codec copy, I would 
actually expect that -threads 1 works (slightly) better.

Why don't you use output.avi for the preview?
-analyzeduration and -probesize may help with the delay.

Maybe it's something!?

Message-ID: <CAHss8oHF9ZK+F=LPuSVwncq8WiYMkAqVNuK=vjuUiK_+dCNbwA@mail.gmail.com>

Hello,
maybe this has already been discussed here:

https://ffmpeg.org/trac/ffmpeg/ticket/1776

but I think there is still something wrong.
I think ffmpeg confuses PAR with SAR.
See the output below. The video is an SD 16:9, DAR is correct, but 64:45 is
the PAR.
SAR is 720/576=1.25.

ffmpeg and ffprobe show the same behaviour.

I'm having trouble with some material I'm converting to DVD with ffmpeg; there is significant ghosting on some players, and some google searches have pointed out that this is often related to interlacing.

The source materialis interlaced, top-field dominant, but when I run it throughffmpeg using "-target ntsc-dvd", mediainfo shows the output as being progressive.

Here is my ffmpeg command line:

ffmpeg -i dora_fairytale_cut.mpg -pass 1 -target ntsc-dvd -b:v 4000K /dev/null && ffmpeg -i dora_fairytale_cut.mpg -pass 2 -target ntsc-dvd -b:v 4000K dora_fairytale_cut_compressed.mpg

My question is, should I be specifying any kind of options to make the deinterlacing happen correctly?  Is this even likely to be my problem?  If you need it, I can also post mediainfo output for the source and output files.

Just forget about this stupid concept of "Storage Aspect Ratio".  In
H.264 terms, SAR is Sample Aspect Ratio which is the same as PAR or
Pixel Aspect Ratio which is used in other standards (I think).  That
link explains it quite well.

Yes ' -flags ildct+ilme' (on both passes) is what I use.

PS. The options ' -flags ildct+ilme' _preserve_ interlacing. This is
accepted by the DVD standard and incurs least quality loss.

I normally do, to prevent my options being overridden by macro settings such
as -target.

Subject: [FFmpeg-user] Transmux H.264 MP4 to MPEG-TS?
Message-ID: <CAAuQz48FBqLUb-CSdhRa8rf6SpDAU2_uD+qvJc1UY7vLjiYv=w@mail.gmail.com>

I have MP4 multiple bitrate (MBR) files that I need to keep the H.264/AAC
streams and transmux into MPEG-TS so that I can package them as HLS
packages. Does anyone know if this is possible with FFmpeg and how I would
pass through the basename to the output as well?

Thanks in advance.

Subject: [FFmpeg-user] About audio convert
Message-ID: <BLU169-DS15C317C0DA0E4742206EA9DAA90@phx.gbl>

Firstly, I am costing your time,but it?s really emergency.
I am developing a program about audio convert?it?s my graduation design for my university.
I use C# call avconv to work it out,but it?s not work.
Here is my call function:
public static void ExcuteProcess(string exe, string arg)  
        {
            System.Diagnostics.ProcessStartInfo p = new System.Diagnostics.ProcessStartInfo(exe, arg);
            p.UseShellExecute = false;    
            p.CreateNoWindow = true; 
            p.RedirectStandardError = true; 
            p.RedirectStandardOutput = true;
            System.Diagnostics.Process listFiles;
            listFiles = System.Diagnostics.Process.Start(p);
            System.IO.StreamReader myOutput = listFiles.StandardOutput;
            System.IO.StreamReader myOut = listFiles.StandardError;
            listFiles.WaitForExit();
            if (listFiles.HasExited)
            {
                output = myOutput.ReadToEnd();
                errorput = myOut.ReadToEnd();
            } 
        }  
Here is my code:
string in_file = "D:\\One.mp3";
            string out_file = "D:\\test.wav";
            //Boolean ret = false;
            //ret = convertAudio(in_file, out_file);
            //if (!ret)
            //    MessageBox.Show("failed!");
            //else
            //    MessageBox.Show("succeed!");

            try  
            {
                ExcuteProcess("ffmpeg.exe", String.Format("avconv -i {0} -ar 44100 {1}", in_file,out_file));  
                //???? 
                MessageBox.Show("????"); 
            }  catch (Exception ex) { 
                MessageBox.Show(ex.ToString());
            }
            textBox1.Text = output+errorput;
And the output be null,errorput not null when I debug the program,
the debug information:

I don?t  understand why it find output format for ?avconv',so would you please help me work it out?
P.S.:when I  run the program separately with cmd.exe,it?s work for converting,so I think it?s wired.
Looking forward to your reply.
                                                                                            Sincerely

ffmpeg can do that, it can also do the entire hls packaging including
m3u8 creation. Check out the example in the docs (the final example in
the section):

avconv is not from FFmpeg, so it is not supported here.

Hi All,

I am having issues getting ffplay to a multi bitrate AppleHTTP/HLS stream,
the stream opens but it never plays yet the individual variant streams play
fine.

Any ideas on how to get a multirate HLS file to play?

Thanks. But if i don't know the offset, how can I get that in an effective
way.  Generating two intermediate files will degrade system i/o performance.

In case when everything is ok, we didn't see message about "timestamp
delta" and have correct bitrate (200-500 kbits/s) in console.

Filling buffer with audio code from our DirectShow audio filter:

HRESULT CVAcademiaStream::FillBuffer(IMediaSample *pms)
{
    CheckPointer(pms,E_POINTER);

	BYTE *pData;
    long lDataLen;

    pms->GetPointer(&pData);
    lDataLen = pms->GetSize();

	CRefTime rtStart = m_rtSampleTime;
	int waitTime = m_timer.elapsed();

	while (!m_isFirstFill && m_iRepeatTime*1000 - waitTime > 0)
	{
		Sleep(1);
		waitTime = m_timer.elapsed();
	}

	ZeroMemory(pData, lDataLen);

	for (int i=0; i<m_captureObjects.size(); i++ )
	{
		SharedMemoryStreamSound* captureObject = m_captureObjects[i];
		bool haveEnoughForCapture = false;
		captureObject->CopyAudioDataBufferForRead();

		haveEnoughForCapture = StreamHaveEnoughData(captureObject, lDataLen);

		if (haveEnoughForCapture)
		{
			FillBufferFromStream(captureObject, pData, lDataLen);
		}	
	}

	m_fillCnt++;
	int currTime = timeGetTime();
	int deltaTime = currTime - m_startTime;

	// Increment to find the finish time
	if (m_isFirstFill)
		m_rtSampleTime += (LONG)m_iRepeatTime;
	else
	{
		m_rtSampleTime += (__int64)m_timer.elapsed()*10;
	}

    pms->SetTime((REFERENCE_TIME *) &rtStart,(REFERENCE_TIME *)
&m_rtSampleTime);

    pms->SetSyncPoint(TRUE);
	
	m_isFirstFill = false;
	m_timer.restart();

    return NOERROR;
} // FillBuffer

We compared our audio filter with some other open-source and tried to
make some changes to get ffmpeg works stable (but unsuccessfully).

Any ideas what can be wrong?

With best regards,
Andrey.

I guess that:
Chrome / Chromium are very "easy" on the WebM specs.

And Firefox is very hard on the specs and doesn't give a (proper)
error warning, only a loading "wheel"...

But I see now 2 things!
1.) I send the wrong URL... Oeps... Sorry!
2.) It's for live WebM streaming...

I am not sure I understand you:

My sample command did not produce an intermediate file.

I may misunderstand this sentence but you 
cannot use / compile / run / whatever 
FFmpeg from inside the MPlayer directory.
(afaict)

Just checkout current FFmpeg as explained 
on http://ffmpeg.org/download.html and 
build it with ./configure --enable-gpl && make

Hello,

When following the tutorial at http://www.tangentsoftworks.com/blog/2012/11/12/how-to-prepare-your-mac-for-ios-development-with-ffmpeg-libraries/

I have the following error when running the first command (configuring FFmpeg for armv7 build)


/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc is unable to create an executable file.

The config.log outputs:

I think you are right with Firefox and Chrome. And that doesn't irritate 
the developers of ffmpeg ...

Excellent help.

Is there also a way to tell if ffmpeg crashed or couldn't finish? I ask
this as the last 'time stamp' was not 100% equal to duration.

crop filter, if you want to remove black pixels, which will change
height of video too.

Nice filter would be to auto detect such black rectangles, and pass
such metadata to crop filter.

The exit code of ffmpeg is accurate.

Well i think than any codec like h264, vp8 will be good,
the only limitation is speed of hardware that is doing encoding vs
compression ratio.
(More compression - better performance is needed)

Lossless only codecs usually do not have that high compression (that
may be mandatory in your scenario) to be
considered useful IMHO,

Just in case anyone else on this list has had the same ghosting problem, preserving the interlacing DOES fix it!  I did have to add `-top 1` to get it to mark it as top-field-first, but otherwise Francois' flags were perfect.  So it's all in one place, here's my command now:

ffmpeg -y -i dora_map_cut.mpg -pass 1 -target ntsc-dvd -b:v 4000K -flags ildct+ilme -top 1 /dev/null &&  ffmpeg -y -i dora_map_cut.mpg -pass 2 -target ntsc-dvd -b:v 4000K -flags ildct+ilme -top 1 dora_map_cut_compressed.mpg

My question now is what do these flags actually do:  prevent a deinterlacing filter from being run, or simply change what the header info says?  Without the flags is the output video still interlaced but incorrectly marked as progressive?

h264 with UDP will be your fastest on a local LAN or managed WAN, if you
want fast startup you will also need to keep your keyframes close.

If pushing out onto a TCP network then go RTSP or RTMP for low latency.
Note that player side buffering is also a big issue for this.

I did some experiments with super low latency HLS for going to Ipad and
could get latency down to about 2 secs but no lower.

Carl informed you that the version of ffmpeg you are using is too old.
Have you updated to the latest version and verified this bug even
exists still?

If you're not willing to do any work to fix a problem you are
reporting, why should anyone else?

Cheers

Tom

Hi Carl,

the issue is the same as :http://roundup.libav.org/issue855

ffserver hangs when feeding it via http
Do you have any idea?




==================================================

hi All,

I got the error when I using vlc to connect ffserver to get video stream,
the video data is from usb webcam.
video stream will stop when the error is occur

the ffserver conf:
<Stream test.mjpeg>
Feed feed1.ffm
Format mjpeg
VideoSize 640x480
VideoFrameRate 30
VideoCodec mjpeg
Noaudio
</Stream>
ffserver command :
ffserver -f /etc/ffserver.conf &
ffmpeg command:
ffmpeg  -f video4linux2 -r 30 -s 640x480 -input_format mjpeg -i /dev/video0
-vcodec copy http://localhost:8090/feed1.ffm

the output log:

==================================================

ffmpeg seems keep running,
but no any video data output by ffserver,
the "invalid stream index" is print out from
/libavformat/fmdec.c, function ffm_read_packet(),
and I also get the error,
function ffm_read_packet(),
case READ_DATA:
 size = AV_RB24(ffm->header + 2);
the value of size is very very large, then ffm_is_avail_data() will return
EAGAIN,
such that there is no any video data can be output.
Does anyone have idea?
Any input is very appreciated!


Best Regards,
Soho

So, a lossless compression algorithm that has high compression ratios
and can run in real time. Let me know when you find it! (this is like
the old software development maxim, "fast, good, cheap: pick two").

Message-ID: <CAFd2cZW2o+0vOY1MGNYAj7Bv+KWbEm393cms3J+XaB2bsJHRfg@mail.gmail.com>

Hi all,

Can anyone give some comments about :
how to co-work between ffserver and ffmpeg?

When ffmpeg is started, I can see ffserver receive data , but the source ip
address is 127.0.0.1.
and when I use VLC from remote host with the url:
http://<ffserver ip>:8090/test.asf
then ffserver can output video stream to the VLC client.

but I confused about:
ffmpeg will keep write video data to feed,
and ffserver should read video data from feed with the format of feed,
ffmpeg may corrupt the content of feed if ffserver is reading at the same
time.
then ffserver can not parse the ffm header.
Can someone give some comments about this mechanism?



the command I use:
ffserver.conf for the stream:
<Stream test.asf>
Feed feed1.ffm
Format asf

AVOptionVideo flags +global_header
VideoSize 1280x720
VideoFrameRate 12
VideoCodec libx264
NoAudio
</Stream>
ffserver -f /etc/ffserver.conf &
ffmpeg -f video4linux2 -r 30 -s 1280x720 -input_format h264 -i /dev/video1
-vcodec copy http://localhost:8090/feed1.ffm > /dev/null 2>&1 &

I will checkout the lastest version of FFMpeg this weekend!
(and the latest libvpx / libtheora libaries)

We have (at the moment) a perfect test environment where
an digital cable tuner is connected (by HDMI) to an Blackmagic
Decklink Card and a test Ubuntu installation.
Also we have a test Ubuntu Server with FFServer installed...

So monday I post the results (live streaming WebM)!

@Hartmut: Do I also have to test something special for you?

Now I am sure the video can be played in windows media player because I installed an application of a third party.
The application supports an especial codec which can be used by windows media player.
Can FFmpeg work with the dll of the especial codec if I find it,
Or I have to get the sourcecode of the codec and complile it with FFmpeg?
Please give me an idea and thanks a lot for any help.

(My question was:)
What is the name of the third party application / 
what is the name of the codec?

cropdetect will give you parsable output you can use in a second pass..

I get my ffmpeg-packages from packman and I informed Carl, that I'm not 
a compiling-type. What I want from the developers, is something like: 
"Yes, it is like you told us and we are working on it" or "We can not 
confirm that" or "We already know but it does not bother us" or "We 
found the bug and fixed it" or so. If the last message arives, then I 
will inform packman, until then I will wait. The developers of FFMpeg 
can not ignore Firefox ...

Regards

Hartmut

Subject: [FFmpeg-user] Weird issue when to link libraries of ffmpeg.
Message-ID: <CAJ7nETH9zZPvmDzKY8=L44q0NveDAyvMF=JRRxXkhz-+hF-R9A@mail.gmail.com>

Hi, All,

I want to  build myself application based on ffmpeg libraries. What I did
are very simple:
(1) Configure, build and install latest ffmpeg;
(2) Copy ffplay.c (changed to play.c), cmdutils.c, config.h,
cmdutils_common_opts.h,  and cmdutils.h from the parent directory of ffmpeg
to my self directory.
(3) Create a simple Makefile as the followings:
all: play
play:play.c cmdutils.c
    gcc -o play play.c cmdutils.c -lSDL -lavcodec -lavformat -lavutil
-lswscale -lavfilter -lpostproc -lswresample

(4) Build it. The errors can be met as the followings:
   ~/fftest/play$ make
gcc -o play play.c cmdutils.c -lSDL -lavcodec -lavformat -lavutil -lswscale
-lavfilter -lpostproc -lswresample
/usr/local/lib/libavfilter.a(buffersink.o): In function `read_from_fifo':
/home/stanley/ffmpeg/libavfilter/buffersink.c:166: undefined reference to
`av_audio_fifo_read'
...(Some other logs are omitted)

But I am sure the right libraries are linked and the function
"read_from_fifo" are defined in the library libavutil.a:
stanley at stanley-P31-ES3G:~/fftest/play$ objdump /usr/local/lib/libavutil.a
-t |grep av_audio_fifo_size
00000480 g     F .text    00000008 av_audio_fifo_size
stanley at stanley-P31-ES3G:~/fftest/play$ objdump
/usr/local/lib/libavfilter.a -t|grep av_buffersink_get_samples
00000790 g     F .text    000001d3 av_buffersink_get_samples

It seems not to be version issue.

Is there anyone meeting the similar issue? Who can give some hints?

Thanks a lot!

Can anyone just test these URLs on ffplay as well and let me know what kind
of playback experience you have?

http://iphonestreaming.abc.net.au/news24/news24.m3u8 (this one has multiple
variant playlists, on Akamai so should play OK in multiple countries once
going)
http://iphonestreaming.abc.net.au/news24/news24_hi.m3u8 (one of the
indiviudal variants)

http://iphone.envivio.com/iphone/downloads/ch6/index.m3u8 (another one with
multiple variant lists)

I need to check the hls.c (I assume this is the correct location) in more
detail but the behaviour I am seeing which is odd is:

Downloads master playlist

Downloads variant playlists

Downloads the 2nd l last ts from each playlist

Downloads the lowest rate playlist

Does a lot of waiting
Eventually plays after long delay

Did some tests from a French IP.
Unfortunately, my message has been refused because of size too large, so
here's a link to the output :
https://www.dropbox.com/s/42kny4g4xbutvu9/ffplayoutput.txt
Not ideal but I didn't want to cut meaningful parts of the ffplay output.

You are linking to static libraries, therefore the order in which you 
link to each library matters.  avfilter probably depends on avutil, so 
try putting -lavutil after -lavfilter

Subject: [FFmpeg-user] How to add padding silence for MP4 container?
Message-ID: <022801ce593f$57283e70$0578bb50$@gmail.com>

Hi All,

 

I'm trying to help someone who needs to delay his audio stream by 2s: he got
given a .mp4 file containing only video and a .aac file with audio which he
needs to mux together delaying the audio by 2s.

 

This works perfectly for MKV:

 

                ffmpeg -i invideo.mp4 -itsoffset 00:00:02.000 -i inaudio.aac
-codec:v copy -codec:a copy out.mkv

 

However, he'd prefer the MP4 container format. Although the ffmpeg command
completes perfectly, no player on my machine respects the MP4 timestamps and
I've seen this reported elsewhere also.

 

So instead of using timestamps with MP4, is there a way to tell ffmpeg to
insert 2s of silence at the beginning of the audio?

 

Many thanks,

Francois

I don't know about using ffmpeg itself, but I fiddle with audio
sync problems all the time and I use sox to generate silence
when I need it. For example:

sox -n -r 48000 -c 2 -e signed-integer -b 16 quiet.wav trim 0 2.0

That will generate 2 seconds of silence in a 16 bit stereo PCM
.wav file format. You can then concatenate that with another audio
file like so:

sox quiet.wav main.wav delayed.wav

I've only ever done this with uncompressed PCM files, don't know
if audio compression might introduce other problems. I tend to
do the mp3 or aac compression as the last step when muxing the
audio and video together with ffmpeg.

TiVo (and correcting audio sync) at:

ffmpeg -i input -af aresample=firts_pts=X

where X is 2 * sample_rate of your audio stream.

you can't use -codec:a copy to insert real silence.

To generate silence with ffmpeg, use the aevalsrc audio filter

http://ffmpeg.org/ffmpeg-all.html#aevalsrc

Then, you can use either the concat demuxer (for which you'll have to
generate the sound separately, ad then prepend it to your existing
audio in two distinct commands) or the concat filter (requires
re-encoding, but will allow you to work with a single ffmpeg command).

ffmpeg -filter_complex 'aevalsrc=0:d=2' silence.aac
ffmpeg -f concat -i <(for f in silence.aac audio.aac; do echo file
"'$f'"; done) -c copy out-audio.aac

OR:

ffmpeg -i audio.aac  -filter_complex
'aevalsrc=0:d=2[slug];[slug][0]concat=n=2:v=0:a=1[out]' -map '[out]'
-c:a libfdk_aac -vbr 3 out-audio.aac

(change depending on the AAC encoder you have)

Well, you actually can, and that is "complicated" way, that others
have mentioned.

Note that in such case: creating silence, encoding silence into aac,
and than concatenating
silence and audio into another stream without transcoding, you can not
have always exact
precision, so 2s delay may be possible or may not (i never tried so dunno).

I just tried and it worked through adjusting the order of the libraries.

Thanks  a lot, Pavel.

I believe there is a dependency for librtmp-dev that should also be added to the Ubuntu desktop users.

An error comes up in the ./configure step for ffmpeg.

Otherwise, very nice set of instructions thank you very much :)

You know, it *is* a wiki ;)
That said, I'm currently compiling using that exact guide (by complete
coincidence) so if I get the same error I'll add that to the guide
myself.

Fixed. Thanks.

Changelog:
* remove librtmp (native support exists)
* remove libfaac (use libfdk_aac instead)
* keep pkg-config (installed by default IIRC, other non-ffmpeg stuff
depends)

Message-ID: <000301ce59ed$fa6b99c0$ef42cd40$@gmail.com>

Hi All,

 

When using an audio bitstream filter to change audio beginning timestamp, it
does not take effect when muxing copied streams, only when the audio is also
being re-encoded. Is this a bug?

 

In the 2nd example below ffprobe shows that the 2s clip was lengthened to 4s
by delaying the 2s audio by 2s. Playback confirms that this was done
correctly. In the first example where only muxing was done audio wasn't
delayed.

When specifying a container DAR for MKV, it does not take effect when muxing

In your command line you are not using a bitstream 
filter - which would allow to change a bitstream

... and all filters (including audio filters) can only 
work on actually processed data, not with -codec copy.

(I don't think this is related to mkv, or do I 
miss something?)
This is ticket #2046
Apparently somebody decided to write a patch and 
did not want to post it to ffmpeg-devel (nor did 
he setup a git clone and asked for a merge).

No, not necessarily specific to MKV; MKV was simply the container format in
which I was hoping to get this working.

I think "time shift" means getting to future or past, right?
FFmpeg cannot take you to furure or past, unfortunately.
But it can do that for particular elementary media stream, see setpts filter.

Subject: [FFmpeg-user] FFv1 interlaced
Message-ID: <51A3038A.7040401@das-werkstatt.com>

Hello,

I wanted to compare FFv1's compression between interlaced and
progressive mode, but the output-files' MD5 checksums are identical.

The documentation I found online only mentions "ilme" and "ildct" [1],
which I presume are meant for lossy encoding. Tim Nicholson once
mentioned to use "-top 0/1" to enable interlaced encoding.

However, the files produced with and without "-top" produce identical files:

-------------
77d97dc84a5b62b493526576f1804e98  output-bff.nut
77d97dc84a5b62b493526576f1804e98  output-progressive.nut
77d97dc84a5b62b493526576f1804e98  output-tff.nut
-------------

Since Derf's collection only contains deinterlaced material, I've chosen
to use interlaced Digibeta material from our archive [2].

Am I missing any flag, or doing something else wrong?
Any hints/info appreciated.

Thank you very much,
Peter B.

The Roku preset provided with the Roku 4.1 SDK is old and outdated. They
really need to update the SDK Encoding Guide with better examples.  Make a
new ffpreset libx264-roku.ffpreset with this:

coder=1
flags=+loop
cmp=chroma
partitions=+parti8x8+parti4x4+partp8x8+partb8x8
me_method=umh
subq=8
me_range=16
g=250
keyint_min=25
sc_threshold=40
i_qfactor=0.71
b_strategy=2
qcomp=0.6
qmin=10
qmax=51
qdiff=4
bf=4
refs=4
direct-pred=3
trellis=1
8x8dct=1
fast-pskip=1
mixed-refs=1



then save that preset here /usr/local/share/ffmpeg/  or to your local ffmpeg
preset folder.

Technically Roku can play video in other resolutions other than 480p 720p or
1080p but it doesn't like it.  I would recommend using 720x480 instead of
854x480.  Roku 1 doesn't like the new ffmpeg however it works fine for Roku
2 and Roku 3.  It will still work on roku 1 but not as good.

Try the encode with the latest version of ffmpeg and use the preset above
like this for 16x9 vob files

ffmpeg -i input.vob -f mp4 -aspect 16:9 -vf yadif=0:1 -vcodec libx264
-bufsize 2000k -profile:v high -level 4.0 -s 720x480 -vb 1000k -acodec
libfaac -ab 128k -vpre roku -r 29.97  -adrift_threshold 0.01 -threads 0
output.mp4


for encoding avi,mpg,mp4 or mov files to roku you will need to remove the
'-vf yadif=0:1'

2 pass looks better for lower bit rates.

For variant stream playback using Apple ios HLS you would need to encode
using the same preset like this   

ffmpeg -i input.vob -f mpegts -aspect 16:9 -vf yadif=0:1 -vcodec libx264
-bufsize 2000k -profile:v high -level 4.0 -s 720x480 -vb 1000k -acodec
libfaac -ab 128k -vpre roku -r 29.97 -vbsf h264_mp4toannexb
-adrift_threshold 0.01  -threads 0 output.1.ts

This will work decently on Roku1 and perfectly on Roku2 and Roku3

Cheers!

Hi!

Our sysadmins compiled a new ffmpeg, but it fails with the following. Any
ideas what went wrong?

Thanks!

Message-ID: <CANK2ZX7f8-My1hdOKcKWUvKbYwtdEM7yzOiaW99P9f7+i750cg@mail.gmail.com>

Hi,
Is there any option similar to swfVfy, used in rtmpdump, for ffmpeg
script. Since svfUrl does not work all time I need this paramater and
I had to use svfVfy.
Thanks..

There is documentation, see rtmp_swfverify in:

Sorry, I asked wrong question, I had seen rtmp_swfverify later, my
problem was with rtmpe protocol that it seems ffmpeg does not support
this protocol while rtmpdump does so. Is there any working for this
issue?

I see rtmpe protocol in documentation you sent, however in my ffmpeg
version I have not. My ffmpeg version is  N-52554-gb691bc4, I download
the latest I think :S

You need to compile it with openssl/gnutls enabled.

Looking at the source, I don't think there is an interlaced 
mode when encoding ffv1.

You can test if such a mode would help compression:
$ ffmpeg -i interlaced -vcodec ffv1 out1.avi
$ ffmpeg -i interlaced -vf il=d:d -vcodec ffv1 out2.avi

If out2.avi is smaller than out1.avi, that would 
indicate that an interlaced mode would help.
The following should allow you to verify that the 
encoding was lossless (and therefore equivalent):
$ ffmpeg -i out2.avi -vf il=i:i -f framecrc -

Tests afaict very welcome!

Looks like it dies with every video :)). I'll kick them in the arse and get
back if everything crumbles :P.

Subject: [FFmpeg-user] ffmpeg segmenter starves when using -re and high
	bitrate
Message-ID: <CAAPxgf=UXWv0XyOTWUugB9YEw5Z36gFTbcMt5zrSsk4uaw7WAA@mail.gmail.com>

Hello,
I would need some help with ffmpeg.


Project:
I'm trying to configure ffmpeg to provide live TV HLS streaming and
transcoding to my Ipad in my home.

Input:
Video source: Hauppauge HD PVR(CBR) - analogue Component + OPTICAL => h264
AAC mpegts
CPU: quadcore when full transcoding is used~ 19-39-% load on all cores.
(the lower bitrate => higher CPU load )
OS: LInux Ubuntu

I had to break down the streaming in two steps. (I had some problem with
buffer handling, i.e. the HD PVR stopped streaming, when I performed
transcoding directly from /dev/video0)

1.) Record input stream to file and store the file in a mpeg TS file.
$ /usr/local/bin/ffmpeg -i /dev/video0 -vcodec copy -acodec copy -y
~/repository/recorded_stream.ts


Approx. 10s delay until starting transcoding process on 'ts' file.

2.)Transcode 'ts' and stream using HLS of live TV to IPAD.
$/usr/local/bin/ffmpeg -re -i ~/repository/recorded_stream.ts  -vcodec
libx264 -b:v 2000k -acodec copy -s 1024x768 -aspect 4:3 -flags
-global_header -map 0 -f segment -segment_time 10 -segment_list test.m3u8
-segment_list_flags live -segment_list_size 0 -y -segment_format mpegts
 stream%05d.ts

Problem Description:
===============
When performing transcoding and using bitrate of approx > 1.2 M (b:v
1000k), the live streaming to the IPAD starves after approximately a few
minutes when new segments are not produced quick enough, i.e. playing the
segments catches up with the available segments from the playlist even if
the player is not started until 3-4 segments are available in playlist. The
QOE result in a short stalls of the live video, and can be reduced by using
pause for a while , but will eventually catch up again and the stalls
resumes.

When the higher bitrate is selected the transcoding FPS goes down 25-27,
which I believe could be the reason for starving the client. TV signal is
NTSC 1080i 59.94 interlaced, or 29.97 FPS, so I would expect the FPS output
to also be 30 FPS for the live transcoded HLS segments.
When I use 1M bitrate an output of 30 FPS is achieved and I don't
experience the starving of file segments.

The same problem can be re-produced with using VLC for viewing the HLS
stream.

I've tried to use forced FPS '-r 30' or '-r 29.97' on the transcoding
process but it seems to have no affect when higher bitrates are used. E.g.
if I set it to -r 32 it will only take affect if bitrate is < 1M.

Would truly appreciate some help to solve the starving file segments since
is significantly impacts the QOE for the end user.

Interesting filter. Didn't know that one.

And a big thank-you to me...  Ran into the problem again today and didn't
remember the answer was to not code "-acodec  copy", but "-acodec
libmp3lame" or whatever you like.  Fixed it again.  Meanwhile, no movement
on the bug fix.  AND WHY, EXACTLY, IS THAT NOT A SOLUTION???

This is sooooo typical.  You have a bug report for this when one is encoding
a mkv, and every thread it's mentioned says stuff like, "have you opened a
report for mp4", etc.  This is real simple. 

The error message is wrong.  If you're going to throw everything up in the
air and quit, then explain why. As it stands the error handler closes the
file and the caller says, "Oh, can't write to file" and exits.  THAT is
something that is not a solution.  Oh, might want to sit down.  This will be
a huge shock.  *whispers*  (You could ignore the error and continue coding
with the sync params from before the error and it would work just fine!  But
you'd rather have the program fail so that you KNOW there was a glitch of no
consequence in the source.  Wouldn't you?  Hey, the programmer know more
about what you want to do than you do!)

-async 1 is a special case where only the start of the audio stream is
corrected without any later correction.  It is often helpful when you have
audio and video out of sync, but the streams are the correct (same) length,
and you just want it to start together and then keeping writing at that rate
without trying to "help you".  Yeah, it's one of the few examples where you
can turn off the wonderful feature that doesn't work.

This is how MS works.  Why improve your product when you can dominate the
market and define professionalism so that no one tries to do any better?  I
worked on that crap from version 0.1 in 1981 until the late '80s and what
I'm seeing in the Linux community now feels like we're going exactly the
same way.  Yeah, I know that's out of left field, but...never mind.   You'll
never get it.  Yeah, it's different.  Ever noticed Calculator, Notepad and
Paintbrush aren't like the rest of Windoze?  Strong central metaphor about
how to use it leveraging everyday experience, ability to think about your
work, not the tool, didactic GUI...  That was me.  People who don't really
get what I'm talking about have accepted the Microshaft philosophy.

And a thread is relevant until the bug is fixed.  Groids.  (For the
linguistically challenged that think anything not in Urban Dictionary is a
neologism, it's a nerd without the socially acceptable spin)

Message-ID: <BAY152-W15560FDC57980B2F1890CF92960@phx.gbl>

I was using ffmpeg to trim a video and it worked but every time I run it the top of the terminal output starts with the error:

"WARNING: gnome-keyring:: couldn't connect to: /run/user/mindbuilder/keyring-jAd74z/pkcs11: No such file or directory"

Does ffmpeg normally access the gnome-keyring or has my ffmpeg been trojaned to steal my encryption keys or what? I don't see why trimming a video would require access to my keyring.

I'm using ffmpeg version 0.8.6-6:0.8.6-0ubuntu0.12.10.1 under xubuntu 12.10 amd64.
Xubuntu uses the Xfce desktop without gnome and so may not have gnome-keyring installed completely or even partially. But then I don't see why ffmpeg should need it installed at all.

Hi guys,

I have a problem when updating ffmpeg. I used avcodec_decode_video before, i
now avcodec_decode_video2 instead. But my programme can not decode the
images. It has only the sound.
Can you please, tell me how i can do ?

Thank you for your help.

Unfortunately you're using a fake "ffmpeg" that is not a product of the
FFmpeg project, and therefore is not supported here. It is a confusing
situation for users, but see the following links for some explanation:

No, it (unfortunately) wouldn't ;-(

1: As said, please do generally not reply to 
30-months old threads, this is very rarely a 
good idea and certainly not in this case (where 
the problem always was unreproducible).

2: I am not a native speaker and I absolutely may miss 
something, but I did neither find a bug report nor a 
feature request in your mail but I have a (tiny) 
feeling that there is something you want to tell us.
If I am right, please provide the command line that 
fails for your together with the complete uncut 
console output (that is everything ffmpeg prints on 
the screen including the command line you used).

I cannot answer your original question (I don't know) but 
please understand that the creators of this intentionally 
broken version of FFmpeg claim that it is exploitable.
(Debian and Ubuntu apparently do not care about security, 
there are rumors that the same is nowadays true for vlc.)

Please see http://ffmpeg.org/download.html for supported 
versions.

Hi All,

 

I'm trying to help another person in an area where I have little expertise
(BluRay encoding) ;-).

 

The question is: "Is there a way to set x264 flags like --bluray-compat
directly?"

 

Does http://www.ffmpeg.org/ffmpeg-codecs.html#toc-Private-Options:

 

"'-b-pyramid integer'

Keep some B-frames as references. 

Possible values: 

'none'

'strict'

Strictly hierarchical pyramid. 

'normal'

Non-strict (not Blu-ray compatible). "

provide the answer?

If not, please tell me the correct answer?

Thanks,

Francois

Yes! use "-x264opts bluray-compat=1

multiple options should be separated with a colon ":" but no spaces.

Subject: [FFmpeg-user] ffm file layout
Message-ID: <CAFd2cZV-4DB6dVay7sYwGkfjum_2NGusm3-u3TyAXkgNmhuciw@mail.gmail.com>

Hi all,

I see the example of ffserver.conf that describes tmp file about feed
# File=/tmp/feed_name.ffm FileMaxSize=5M

Could someone explain the layout of /tmp/feed_name.ffm?
how to map the struct FFMContext to the file?
Because I got the serious problem about header in struct FFMContext that
are corrupt.
ffserver can not find the valid data content of struct FFMContext.
Does someone have idea?

HI!

The newest ffmpeg produces an invalid image tile, after executing the
following:

$ ffmpeg -i 00002.MTS -an -vsync 0 -vf
'select=isnan(prev_selected_t)+gte(t-prev_selected_t\,2),scale=90:45,tile=10x9'

An older version with the same command produces a correct result:

$ ffmpeg -i 00002.MTS -an -vsync 0 -vf

Patch on the devel mailing list.

It would be nice to see which commit introduced the regression though.

This is not completely true, every time I sit down to play with
FFmpeg, I look up at the clock and find I have been transported in to
the future, usually by at least several hours.

I've tested compression performance and the files are sometimes  
smaller, sometimes bigger.

I ran it on 4 files:
1) 1min documentary (anamorphic Digibeta material) [1] - (9 MB bigger)
2) 1min interview (anamorphic Digibeta material) - (5 MB bigger)
3) 1min low-motion "Heldenplatz" (VHS) [2] - (15 MB smaller)
4) 10min holiday/family video (many cuts) (VHS) - (300 MB smaller)

Encoding the deinterleaved fields were bigger with Digibeta and  
smaller with VHS.

Therefore I concur with you, that with this kind of compression the  
impact of differing between progressive/interlaced encoding seem  
negligible. I've also compared FFv1.1 vs FFv1.3: Approximately same  
results.
The compression gained there is probably not worth the hassle of  
having an interlaced-mode.

Regards,
Pb

Subject: [FFmpeg-user] why ffserver receive data from 127.0.0.1 repeately
Message-ID: <CAFd2cZXE_Z6QSqNniOgWPnAZSdL6R8gBApzp2MDkohy2mPm4Ag@mail.gmail.com>

hi All,

I got the error when I using vlc to connect ffserver to get video stream,
the video data is from usb webcam.
video stream will stop when the error is occur.
I can see ffserver receive data from 127.0.0.1 and ffserver will write data
to /tmp/feed1.ffm
it seems ffserver just write packet "data" of struct FFMContext , no header
to /tmp/feed1.ffm.

but I do not know where is the data about the element "header" of struct
FFMContext.
Because I do not see, ffmpeg write data to socket 127.0.0.1


ffmpeg seems keep running,but no any video data output by ffserver,the
"invalid stream index" is print out from /libavformat/fmdec.c, function
ffm_read_packet(),
and I also get the error,
function ffm_read_packet(),
case READ_DATA:
 size = AV_RB24(ffm->header + 2);
the value of size is very very large, then ffm_is_avail_data() will return
EAGAIN,
such that there is no any video data can be output.
Does anyone have idea?
Any input is very appreciated!



===============================================================
the ffserver conf:
<Stream test.mjpeg>
Feed feed1.ffm
Format mjpeg
VideoSize 640x480
VideoFrameRate 30
VideoCodec mjpeg

ffserver command :

ulf,

Have you tried using the "-hls*" options instead of -segment.* options?

e.g.

ffmpeg -re -i VIDSOURCE -y  -c:v libx264 -b:v BITRATE -vprofile baseline
-preset medium -x264opts level=41 -threads 4 -s RESOLUTION -map 0:v
-map 0:a:0  -c:a libfaac -b:a 160000 -ac 2   -hls_time 10
-hls_list_size 6 -hls_wrap 18 -start_number 1 stream.m3u8

Would be curious to see if it changes anything.

FC.

Hi FC,
No I haven't, and I just tried the "hls" option and preliminary it looks
like it's working. Great stuff!!
I had to remove parameter "start_number 1" since it caused the IPAD to go
back to old segments.
Need to read up on this HLS in the ffmpeg documentation, since I truly
thought that the segmenter was ffmpeg:s HLS streamer.
Thanks again FC, truly appreciate your help!

Subject: [FFmpeg-user] how ffmpeg send video data to ffserver
Message-ID: <CAFd2cZXLJ+LPAXN-vaFyjtO-ROFrjjeQJwsk3bKZG-JpLL4JQw@mail.gmail.com>

Hi All,

the command line I use:
ffmpeg -f video4linux2 -r 30 -s 640x480 -input_format mjpeg -i /dev/video0
-vcodec copy http://localhost:8090/feed1.ffm

after trace ffmpeg code, I see in do_streamcopy(),
do_streamcopy() will call write_frame(), and next
write_frame() will call av_interleaved_write_frame(),

I do not see the code about socket write.
Because I see ffserver will keep receive data from socket.
Does anyone have idea about this question?

where is the code that help ffmpeg to send data to ffserver?

No prob.
Please share your final working command when done :)

Subject: [FFmpeg-user] transcoding a live stream into an rtmp stream which
 uses h264 and aac codec
Message-ID: <1369840479992-4659382.post@n4.nabble.com>

Basically we are transcoding a live stream into an rtmp stream which uses
h264 and aac codec. It works fine for the first 13 minutes but after that it
crashes and automatically closes the conversion. After the research, it
seems like it is a duplexing issue.Here is the complete dumped error is
attached to this post, and also a link to pastbin:
http://pastebin.com/3WHGcfdj <http://pastebin.com/3WHGcfdj>   3WHGcfdj.txt
<http://ffmpeg-users.933282.n4.nabble.com/file/n4659382/3WHGcfdj.txt> 
Please have anyone here experienced this type of error ? That can actually
offer us some sort of advice in what to do, to solve this issue...

Subject: [FFmpeg-user] problem with subtitle fonts.
Message-ID: <CAM9C_CZ4GSvmBLtOOCJ4thFJPd3tBf6Oo3jYRXx0=AZcwK_VdQ@mail.gmail.com>

I want to burn subtitle with chinese fonts and it is using the arial,
getting ascii binary instead of chinese fonts,  How can I tell it to use
some other fonts? I am running in Freebsd or Linux.

Getting the error: [Parsed_ass_0 @ 0x80ae2e7a0] Glyph 0x53A not found,
selecting one more font for (Arial, 80, 0)

Subject: [FFmpeg-user] iphone auto-rotation?
Message-ID: <CACrj35E8f5DPdr_oByiNCZS7tJQDC5GsNMCM_k+Y9Thk6CE7jg@mail.gmail.com>

I run a service that publishes videos.  Amazon does the actual conversion
to h264 but I'm using ffmpeg to capture frames to make thumbnails.  I have
a problem now where iPhone 4 videos have a weird rotation that amazon
handles properly but ffmpeg is ignoring.  So i'm getting rotated thumbnails.

I checked the file with mediainfo and the metadata says there is a 90
degree rotation.  What can I do to get ffmpeg to auto-rotate using this
information?

My version info is ...

Thanks for the reply

I have this thread

Do you think it really works for live streaming to have a time shift?

Thanks again

Subject: [FFmpeg-user] VP8 encode need help!
Message-ID: <CAB7tV28yoN9FH7_ZOs6HA8Ggru6zkMV+XvBNjh02TehtUf+B3g@mail.gmail.com>

Hi all,

I am using the following command:
ffmpeg -i <input.webm> -c:v libvpx -b:v 5M -slices 1 -r 30 -s 1920x1080
-c:a libvorbis -ac 2 -b:a 128K -ar 48K -t 60 out.webm

I have encoded 15 and 60 fps content as well by changing the values on -r

Now, when i check the generated output files, when i divide the number of
frames of the generated clip and divide with clip duration. It still shows
that the clip is 23.98 fps which is equivalent to that of the source
content.

Can anyone please help me on this.


Thanks
Nitin

Please show the complete ffmpeg console output that results from your

Awesome. Thanks.

I don't have PHP.  Is there any other language I could use that supports
ffmpeg?  Something that I can use in Linux?  I have a node module running
ffmpeg (fffmpeg) but it only talks to the ffmpeg command-line.  Perl,
Python, bash, java, ruby, javascript?

I would hate to install and support PHP for just this.

I don't have anything to help you, i just want to say that likely i
have understood what you mean as "time shift" - it's seeking. You want
to enable seeking back up to 1 hour on a live stream. Is that correct?
Not being aware of any smarter solution, i'd say this task requires
developing special application using libavformat.

It has nothing to do with PHP, this is just a simple heuristics how to
build the ffmpeg command line to fix the orientation of the images that u
grab -
for rotation 180 add " -vf vflip,hflip", for 90 add "..." , etc.
The source rotation data can be retrieved with mediainfo of ffprobe.

I am still getting this problem.

situation.

Is there a way to search the archives?

Thanks!

Hi All,


If I would like to implement a stream server and it have to save video data
to local disk simultaneously when ffserver output the video stream,
is it possible to use ffmpeg +ffserver?

rtmpdump does not require ffmpeg to build.

I don't get it. You can't link ffmpeg successfully, but you have a
binary to show us which reports its version? Then it must have been
linked.

You see, I don't understand the problem. Even if you were trying to
compile ffmpeg with librtmp support (the other way around from what
your first sentence says), where do you have that binary from?

Are you sure that did a "make clean" before running ./configure with
new options? This seems like librtmp was found at configure time 8and
possibly compile time), but not at link time. Your installation of
librtmp may be borked, e.g. by two conflicting versions.

A good start would be to show us the full command line and output of
your ./configure call. Then there may be some hints in config.log.

Hi!

Is it safe to assume, that whenever an unrecoverable error occured, the
colored output line will contain the following color definition?

.[1;31mWhatever blabla


I need this, because when using multiple outputs, if the "main" output
succeeds, but the secondary one fails, then the ffmpeg exit code is still 0.

Subject: [FFmpeg-user] ffplay feature request: advanced mouse control
Message-ID: <CAG6Cn5ZN6e_GauPffYpR2kwMDA0iKLPpyB29sUHBwwfJescrAQ@mail.gmail.com>

Hello!

I use ffplay very often, thanks to all developers and maintainers.
There is one thing breaking happy everyday usage: accidental mouse
clicks in fullscreen mode, it seeks to a random place.

It would be nice to have advanced mouse control interface also:
pause/play and zoom. I have an idea about an interface and hope you
will comment it.

Left mouse button (LMB):
    click - restore zoom to 100%
    push, select region, unpush - zoom to the selected region
Right mouse button (or Alt+LMB):
    click - pause/unpause
Middle mouse button (LMB+RMB on 2-buttons-mice or Ctrl+LMB or Shift+LMB)
    click - seek (as left mouse button acts now)

Middle mouse button click is less accidental than Left mouse button
click for most users.
All these Key+Mouse combos are needed by people with 1-button-mice.

Thanks in advance, please share your opinion.

clicking on the left seek toward the beginning, clicking on the right seek
toward the end, etc.

Subject: [FFmpeg-user] Repeating image tiles
Message-ID: <CAD-_qAH9_Dkwa_=mXy7SNKa1Ss3PFbngmv4=dwuqO5tg7jD=ug@mail.gmail.com>

Hi!

I use the following command line to convert flv movies to mp4 and also
create a 10x9 image tile. Each tile gets written at 2 second intervals, so
a full image tile should be written after every 3 minutes. My problem is,
that with the followinging 9 minute video, ffmpeg creates a lot (100+) of
repeating (md5 sums match) tiles. Any idea what might be the problem?

Source video file:
https://www.dropbox.com/s/9uiup4uc9u3pdg7/v20.flv.flv

$ ffmpeg -i v20.flv.flv -y -movflags faststart -vf 'scale=320:240'
'video-20.360.mp4'  -vf
'select=isnan(prev_selected_t)+gte(t-prev_selected_t\,2),scale=90:45,tile=10x9'

Since you are using the select filter, it is probably the image2 muxer
behaving in constant frame rate. Try adding -vsync vfr.

If if true in some cases (when termianl supports colors) that is
hardly right thing to do.

Hey Mortiz,

Thanks a lot for your help.

To be more specific, I had already compiled ffmpeg. I wanted to recompile
ffmpeg with rtmpdump support.

I apologize for my inexperience regarding ffmpeg. I have rtmpsump already
compiled and installed.

How should I clean up my librtmp installation?

Best Regards.

Hi edwards.

I think you want to have ffmpeg that supporting rtmp input. Previously I had an experience with rtmpdump; piping it's output to the VLC; then VLC could play it. maybe ffmpeg also work as this. Also?I am so excited to receive rtmp stream directly by ffmpeg. I'll follow this post.?

Hello,

I have M2TS-files with TrueHD and DTS-MA audio tracks.
Is it possible to strip these extensions so that the audio is only AC-3 and/or plain DTS?

I looked at the list of bitstream filters, but couldn't find anything...

Thanks,

Subject: [FFmpeg-user] ffmpeg and ffserver to transcode and stream rtsm to
	rtmp? Please Help me.
Message-ID: <80693865dc254dd7127841eb96408501@mail.gmail.com>

Hello,

On Debian 6, I am trying to use ffmpeg and ffserver to transcode and
stream an rtsp feed from an IP camera in order for visitors to play via
browser.

It's a brand new camera - I'm struggling to make this work, and I am not
familiar enough with it to know what I am doing wrong.  I have tested the
camera by successfully viewing the rtsp feed in VLC as well as a hosted
streaming provider.  This all works, so I know the camera and rtsp is
functioning.

Flow looks like this:  [IP Cam] --> RSTP h.264 stream
(rtsp://192.168.0.25:554/cam0_0) --> [FFMPEG] --> [FFSERVER] (Port 9999,
Feed1.ffm) --> Web Browser

I am using ffmpeg/ffserver installed from Debian repositories via apt-get
install ffmpeg. It seems as though it's running, but when I either try to
browse to http://host:9999/test.swf or I try to use VLC to open the
network stream, I get a white screen.  When I stop ffmpeg, I get this very
faint, ghostly (near indistinguishable) outline of a still of the video.

I'm working on a project for a customer, and I would like to know how to
do make this work and to be able to repeat it so I can use it in the
future on other projects as well.  I've spend a ridiculous amount of time
on this and I've reached a dead end.  I would be willing to hire an expert
to help me with this if this is possible to do and I can't do it on my
own.  (I don't want to use a solution like Red5 or Wazoo -- I want to know
how to do this and be able to do this with ffmpeg.  Not because I'm cheap
- I'm willing to spend money for help, but I want to have control of the
tools I use for my customers.)

Please help!  ---  Is what I am trying to do even possible in this
configuration?

---

My ffserver.conf file looks like this:

Port 9999
# bind to all IPs aliased or not
BindAddress 0.0.0.0
# max number of simultaneous clients
MaxClients 1000
# max bandwidth per-client (kb/s)
MaxBandwidth 10000
# Suppress that if you want to launch ffserver as a daemon.
NoDaemon

<Feed feed1.ffm>
File /tmp/feed1.ffm
FileMaxSize 5M
ACL allow 127.0.0.1
</Feed>

<Stream test.swf>
Feed feed1.ffm

VideoBufferSize 80000
VideoBitRate 100
VideoQMin 1
VideoQMax 5
VideoSize 704x480
PreRoll 0
Noaudio
</Stream>

---

1. I run the following command: ffserver & ffmpeg -i
rtsp://192.168.0.25:554/cam0_0 -vcodec http://localhost:9999/feed1.ffm

1A. (I also run ffserver from one console session and ffmpeg from another
-- same results.)

ffmpeg has native support for RTMP (both input and output), and can
also support librtmp but I'm not sure why you would need that. See
"ffmpeg -protcols" and the docs:

I am trying to compile FFMPEG with RTMP support for Serviio. Apparently it
needs that piece for various feeds and such.

Sajjad makes a great point, that is precisely what I was trying to get at
(I apologize for the misrepresentation).

FFmpeg always strips AC-3 from TrueHD / 
it is not possible not to strip with FFmpeg.

Really? I always thought that "invisible" horizontal axis for seeking
is made of all window and mouse click seeks to the clicked position.

man ffplay:
       mouse click
           Seek to percentage in file corresponding to fraction of width.

I recompiled FFMPEG just fine. If I want to recompile FFMPEG with rtmpdump,
do I have to clear things out with"

make clean

Then recompile rtmpdump support?

Sorry for the dumb question.

Subject: [FFmpeg-user] Effective bit rate of video
Message-ID: <001a01ce5d9d$b1e1b190$15a514b0$@vasc.com.vn>

Hi. 

This is a command line of ffmpeg which I use 

-i udp://233.19.205.56:5501 -filter:v yadif=0:0:0,fps=25 -vcodec libx264 -vprofile main -level 30 -g 64 -maxrate 1400k -bufsize 2800k -s: 720x576 -r 25 -crf 1 -ac 2 -ar 48000 -b:a 128k -filter:a volume=2 -f mpegts udp://230.1.1.1:5501?pkt_size=1316 

When I run this command, I saw that on cmd the output bit rate is over 1400k about 1600k and I play on VLC the input bitrate video is not 1400k. The bit rate video is always change <1400k or >1400k. So how to force the ouput bit rate video is constant or at least constant around 1400k.

Thanks your support.

Best Regards

then ffserver is not necessary?

if my ffmpeg command is :
ffmpeg -f video4linux2 -r %d -s 1280x720 -input_format h264 -i /dev/video1
-vcodec copy http://localhost:8090/feed1.ffm > /dev/null 2>&1 &
and I also to start ffserver for http service,
then how to get the result I want?

Subject: [FFmpeg-user] Possible to use named pipe between ffmpeg and ffplay
	on Windows?
Message-ID: <51A84664.9050304@vultaire.net>

Hi,

Let's say I have two named pipes: "\\.\pipe\piper_in" and "\\.\pipe\piper_out".  The pipes are being 
managed through an intermediate process, basically working as a poor man's mkfifo on Windows.  The 
intent is to have ffmpeg write to \\.\pipe\piper_in, and ffplay read from \\.\pipe\piper_out.

ffplay seems to work fine with this.  I connect it first via:

     ffplay -f rawvideo -pixel_format bgr24 -s 1280x720
         -i \\.\pipe\piper_out

The problem comes when I try to run ffmpeg with the named pipe as
output.

Command line:

     ffmpeg -f dshow -rtbufsize 1000000k -s 1280x720 -r 30
         -i video="Logicool HD Webcam C310"
         -f rawvideo -vcodec copy -an
         \\.\pipe\piper_in

This results in the following:

     File '\\.\pipe\piper_in' already exists. Overwrite ? [y/N] y
     \\.\pipe\piper_in: No such file or directory

Basically: rather than writing to the pipe, ffmpeg attempts to create a new file.

Is there any way to make this work?  Or is this sounding like a feature request for the devs?


Best Regards,
Paul Goins

Subject: [FFmpeg-user] Problem with amerge
Message-ID: <51A867D1.3000802@yahoo.com>

Been updating some of my scripts to use amerge with filter_complex
instead of -f lavfi and hit an issue.

The following command line works properly (except that seeking is not
frame accurate, but thats another issue):-

ffmpeg -f lavfi -i \
"amovie='Pipeline_test/BPR10407_01.mov':si=2 [a1];
amovie='Pipeline_test/BPR10407_01.mov':si=3 [a2];
[a1][a2] amerge, aformat=sample_fmts=s16:channel_layouts=stereo" \
-i 'Pipeline_test/BPR10407_01.mov' \
-map 1:v -map 0:a \
-vf "crop=720:576:0:32, setdar=4/3, scale=720:576:interl=1 [scaled];
movie='dog-.png' [logo]; [scaled][logo] overlay=80:60" \
-target pal-dvd -b:v 8000k -minrate 8000k -maxrate 8000k \
-flags +ildct+ilme -top 1 \
-b:a 192k -ar 44100 \
-ss 1089.280 -t 53.20 \
-y 'coded/out.mpg'


However the updated version produces an error and the resulting file has
a large "echo" offset between the 2 audio channels. I have highlighted
the error line which is  near the bottom:-

Does it work with pipe://pipe/piper_in ?

FFmpeg assumes piper_in is a file (that it overwrites) 
if you don't specify anything else.

Try this command:

ffmpeg -f dshow -rtbufsize 1000000k -s 1280x720 -r 30 -i video="Logicool HD
Webcam C310" -an -c:v libx264 -q 0 -f h264 - | ffmpeg -f h264 -i - -c copy
-f mp4 c:\file.mp4 -f copy pipe:play | ffplay -i pipe:play

1st instance of ffmpeg will capture wideo from webcam, encodes it to x264
and sends to a pipe.
2nd instance of ffmpeg grabs stream from pipe, saves it to file and sends
stream to pipe:play

Hi,


I am currently trying to transcode an udp TS stream which contains 1 video stream and 4 audio streams.

I'm using this command line:

ffmpeg -i "udp://239.255.0.10:1234?fifo_size=1000000" \
? ? -map 0:0 -codec:v libx264 -s 1280x720 -profile:v baseline -preset:v superfast -g 125 -vb 1500k -map 0:1 -codec:a aac -ab 64000 -ar 48000 -ac 2 -strict experimental -f flv rtmp://host/1/720p \
? ? -map 0:0 -codec:v libx264 -s 800x450 -profile:v baseline -preset:v superfast -g 125 -vb 800k -map 0:1 -codec:a aac -ab 64000 -ar 48000 -ac 2 -strict experimental -f flv rtmp://host/1/450p \
? ? -map 0:0 -codec:v libx264 -s 384x216 -profile:v baseline -preset:v superfast -g 125 -vb 300k -map 0:1 -codec:a aac -ab 64000 -ar 48000 -ac 2 -strict experimental -f flv rtmp://host/1/216p \
? ? -map 0:0 -codec:v libx264 -s 1280x720 -profile:v baseline -preset:v superfast -g 125 -vb 1500k -map 0:2 -codec:a aac -ab 64000 -ar 48000 -ac 2 -strict experimental -f flv rtmp://host/2/720p \
? ? -map 0:0 -codec:v libx264 -s 800x450 -profile:v baseline -preset:v superfast -g 125 -vb 800k -map 0:2 -codec:a aac -ab 64000 -ar 48000 -ac 2 -strict experimental -f flv rtmp://host/2/450p \
? ? -map 0:0 -codec:v libx264 -s 384x216 -profile:v baseline -preset:v superfast -g 125 -vb 300k -map 0:2 -codec:a aac -ab 64000 -ar 48000 -ac 2 -strict experimental -f flv rtmp://host/2/216p
? ??

With this command line I encode 6 streams, 3 quality for 2 langs.
In this command line I, for example, transcode two times the 1280x720 video resolution which I think is not optimized.

Can you tell me, if it is possible to encode only one time the video and add different languages to this video?

In fact, to optimize cpu usage I would like to encode only once each video resolution

? ? ? ? ? ---- 1280x720 ------> 3 outputs with audio 0:1, 0:2, 0:3 ...
? ? ? ? ?|
TS input --------- 800x450 -------> 3 outputs with audio 0:1, 0:2, 0:3 ...
? ? ? ? ?|
? ? ? ? ?----- 384x216 ------> 2 output with audio 0:1, 0:2, 0:3 ...

I am also surprised by the cpu usage of this command line. With a 8 cores X3450, this command line use 30% on all cores. When I add 3 outputs the cpu usage increase slightly but ffmpeg is not able to do 25 fps transcoding and then I see buffering on the output streams. I tried to nice ffmpeg but It is not better. I hoped to encode more streams with this CPU.?

??

what do you want?
more cpu usage or less?

"I tried to nice ffmpeg" and "I hoped to encode more streams
with this CPU" is the exactly opposite!

with "-threads 1" you would only use one core
with "-threads 8" you would have 8 parallel encodings

but however, not all an be encoded in parallel

Shouldn't you use -threads 0 for libx264 to get maximum multi-core usage?

why should you do this?

it uses as much cores as available *as default*
but not all can be done in parallel and since the OP
refers to nice at the same time as "more with this CPU"
nobody knows if he wants his CPU more or less used
