Subject: [FFmpeg-user] flv video truncated in conversion to mxf
Message-ID: <1335826226.8234.YahooMailNeo@web39306.mail.mud.yahoo.com>

I am using ffmpeg (version 0.10.2) to convert an flv (Sorenson Spark video & Speex audio) into an MXF file. I get a warning "Missing Speex header, assuming defaults." and transcoding proceeds. But?the 50-second input file is truncated to 46 seconds in the MXF output.?
This video was generated using a Flex app and FMS Server 4.0.?
I have provided detailed outputs below.
Would greatly appreciate it if anyone can shed any light on why the file is getting truncated.

Thanks,
Suneetha

PS:?One thing I noticed is that MediaInfo shows the Audio Sampling rate as 5500 Hz while ffmpeg is assuming that it is 16000 Hz. I tried to force ffmpeg to use 5500 as the Audio sampling rate for the input file by providing "-ar 5500" before providing -i <input-file>. But that gave me the error "Option sample_rate not found.".

Command line I am using:
====================
ffmpeg -i ~/MEDIA/test7.flv -ss 0.000000 -r 29.97 -threads 4 -vcodec mpeg2video -pix_fmt yuv422p -q:v 1 -intra -ar 48000 -async 1 -q:a 1 -f mxf test-out.mxf
(I tried adding the -t option. That did not help)?

Output
=====
$ffmpeg -i ~/MEDIA/test7.flv -ss 0.000000 -r 29.97 -threads 4 -vcodec mpeg2video -pix_fmt yuv422p -q:v 1 -intra -ar 48000 -async 1 -q:a 1 -f mxf test-out.mxf

No, and I believe that includes any external libraries supported by
FFmpeg. Decoding is supported natively, however.

$ ffmpeg -codecs 2>&1 | grep vp6
 D V D  vp6             On2 VP6
 D V D  vp6a            On2 VP6 (Flash version, with alpha channel)
 D V D  vp6f            On2 VP6 (Flash version)
 D..... = Decoding supported
 .E.... = Encoding supported
 ..V... = Video codec

If you want support on this mailing list, you will have to post 
the command line you used to produce the output file that 
is not correct together with the complete, uncut console output.

The reason I did not ask for complete, uncut MediaInfo output is 
that I do not (easily) remember an issue where it helped.

Is the problem also reproducible with the internal ASP encoder?
(Problems that do not depend on external libraries typically are
fixed easier / faster.)

Please try current git head and / or provide the input sample.
(Why do you use -async 1? Is it needed for A/V sync?)

Message-ID: <CADgrf6d2HWxeKe3VqJ16sHPE1Q8r95M0hJ_RTJ3t-9kWh28m6A@mail.gmail.com>

Hi all,
i am new to ffmpeg ,
i want to measure the performance timing of ffvp8 on Beagle Board with
linux image.
ffmpeg is configured with following options,

./configure --target-os=linux --arch=arm --cpu=cortex-a8
--enable-cross-compile --cross-prefix=arm-none-linux-gnueabi-
--cc=arm-none-linux-gnueabi-gcc --extra-cflags="-Wall -pipe -mcpu=cortex-a8
-mfpu=neon -mfloat-abi=softfp"

make

then i run the stream with options,

./ffmpeg -c:v vp8 -benchmark -i 2_part_015.ivf  test2.yuv

i get utime = 38.03 secs for total transcode process.
when i take utime for only vp8_decode_frame() function(in vp8.c file) it is
31.14 secs

which one i want to take to compare with libvpx ?

Is ffvp8 still faster than libvpx ?


please correct me if anything is wrong.


regards,
skc

you are aware that flash supports H264 Baseline?

no, it is not possible, there is only a DEcoder for VP6

I don't know much about the format, so I don't know how this should 
be done correctly.

1) 
Here is ALL the info you need: http://pastebin.com/ieL8UUFG
2)
The MediaInfo info is not cut, it's complete
3)
What's internal ASP encoder?

Hi
I think this means use FFmpeg's internal mpeg4 encoder instead of the external libxvid encoder.

To me, your command looks good:-
ffmpeg -i avisample.avi -vtag XVID -vcodec libxvid -s 160x128 -aspect 5:4 -r 15 -acodec mp2 -ar 44100 -ac 2 -ab 128k output.avi

But try this command instead:-
ffmpeg -i avisample.avi -vtag XVID -vcodec mpeg4 -s 160x128 -aspect 5:4 -r 15 -acodec mp2 -ar 44100 -ac 2 -ab 128k output.avi

Hi
I don't have a solution...

just some suggestions...

Maybe your source file "avisample.avi" is no good/not suitable.
Repeat the libxvid/mpeg4 runs with some different videos.

Maybe there is something peculiar about the *device*.
Research manufacturers' website/forum/helpline.
Also scour google to see if other people have good settings for FFmpeg or MEncoder or whatever.

Good luck ;-)

Message-ID: <CAHb4MBhUB2pwMrGR4Pf7=FsQLWA7vLi05T29t9Wm52QkC9Ut6w@mail.gmail.com>

Hello,

i have a problem converting a mkv file with multiple audio streams
with the -acodec copy command.

Here is my command:
fmpeg -i foo -sn -acodec copy -vcodec libx264 -preset slow -tune film
-profile high -crf 21 -threads 0 -s hd720 foo2

This works perfect, except the second audio stream got lost after this.
There are two audio streams #0:1 and #0:2, but "Streaming mapping"
shows only #0:1 -> #0:1 (copy).

Thanks

Dieter

Thanks for your response Carl.
Yes I am using "-async 1" for A/V sync.
Attached is the sample where I see the issue.
It has some audio at 11s, 22s and 40s.
Thanks again,
Suneetha

Please try current git head and / or provide the input sample.
(Why do you use -async 1? Is it needed for A/V sync?)

Subject: [FFmpeg-user] Problems Converting JPEG Image Files to MPEG Movie
	file
Message-ID: <11205021458.ZM201911@vigyan.com>

     I've been working on this for about a week now.  I've read the manuals
and done some Googling, but just can not figure out what I'm doing wrong.
It is probably something obvious I'm missing.  I have over 15,000 jpg files
I want to combine into a single mpeg movie file and everything I've tried
fails.  If I try to process all the files I get a `Segmentation fault'.
If I try to process 100 files or more I get an error message and no output
file.  If I process 99 or less files, I get my output file fine.  My basic
command is:

	ffmpeg -i *.jpg out.mpeg

The above command works for < 99 image files.  The moment I add one more file,
I get:

	"Error while opening encoder for output stream #0.0 - maybe
	 incorrect parameters such as bit_rate, rate, width or height"

I get the above error from 100 to 118 files.  With 119, I get the
`Segmentation fault'.  This is the end of the output:

	Input #0, image2, from '2012041200010001.jpg':

I'm running under Scientific Linux 5.7, a Red Hat rebuild.
ffmpeg version is 0.6.5  This is the most recent RPM build I've found.
The system has 4GB memory and 16GB swap.  I've used the `limit' command
to put all my resources to `unlimited', except for descriptors=1024 and
maxproc=36864.  The last 2 are the defaults and seem reasonable.  I'm under
a time crunch so any help would be greatly apreciated.  Thanks.

Subject: [FFmpeg-user] acodec copy and multiple audio streams
Message-ID: <CAHb4MBh_EkY-WjVSRHnd=rpM2BXEAf919N5vH_5Tyte4zqpEeQ@mail.gmail.com>

Hello,

i have a problem converting a mkv file with multiple audio streams
with the -acodec copy command.

Here is my command:
fmpeg -i foo -sn -acodec copy -vcodec libx264 -preset slow -tune film
-profile high -crf 21 -threads 0 -s hd720 foo2

This works perfect, except the second audio stream got lost after this.
There are two audio streams #0:1 and #0:2, but "Streaming mapping"
shows only #0:1 -> #0:1 (copy).

Thanks

Complete, uncut console output missing.
(needs -map for all audio streams that you want to copy)

Please try to imagine what the shell does with "*.jpg" and you 
will understand that this cannot work.
If your files are pic001.jpg - pic999.jpg use:
ffmpeg -i pic%3d.jpg
If they are named (completely) differently, you will have to 
use the new glob syntax, unfortunately, I don't know how it 
works (yet)...

This is too old (apart from the fact that it produces the segfault 
you are seeing), please use current git head.

I suspect the reason is that audio ends prematurely and the 
mxf muxer stops muxing if no audio is provided (but this is 
just a guess).
If you decide to open a ticket on trac, please provide the 
sample and complete, uncut console output (again).

Yes, I noticed that your working video was created with MEncoder.

And no, I don't really believe that MEncoder can do anything that FFmpeg can't.

But if you want to try it out...

This command might be OK:-

mencoder avisample.avi -ffourcc XVID -vf scale=160:128 -aspect 5:4 -ofps 15 -ovc lavc -lavcopts vcodec=mpeg4 -oac lavc -lavcopts acodec=mp2:abitrate=128 -o output.avi

yes, there is
mencoder can join multiple video into one file while transcoding, even
using 2pass mode
mencoder can use vfw based codec to encode video
b^-^

@shimmy:
i still believe that the avi container is the fault
so, before trying guano's suggestion, do you care to try this first?
it doesn't transcode the video just remux it, so it should be fast ;)

mencoder -oac copy -ovc copy -o output.avi filefromffmpeg.avi

Thanks for your answer. The full output is very long, the audio parts are:
 Stream #0:0: Video: h264 (High), yuv420p, 1920x1080 [SAR 1:1 DAR
16:9], 23.98 fps, 23.98 tbr, 1k tbn, 47.95 tbc
 Stream #0:1(eng): Audio: dts (DTS-HD MA), 48000 Hz, 5.1(side), s16, 1536 kb/s
 Stream #0:2(eng): Audio: ac3, 48000 Hz, 5.1(side), s16, 640 kb/s (default)

and then:

Stream mapping:
Stream #0:0 -> #0:0 (h264 -> libx264)
Stream #0:1 -> #0:1 (copy)

what i'am doing is making a bunch of temporary simlinks with correct
naming (as noted), then feeding them to ffmpeg, then deleting them.

Bo?tjan

p.s. are there any docs about the new glob syntax?

The error message is here:

The explanation is in the FAQ: "-profile option fails when encoding H.264
video with AAC audio".

Subject: [FFmpeg-user] loosing fps damaging index
Message-ID: <4FA28947.4040504@gmail.com>

Hi all,

I record a logitech pro 9000 webcam with ffmpeg, using libx264 I realise 
lately when the FPS drop the file then become corrupted and is unreadble 
after the fps drop - image is fix and the video remain at the same time.

As I use a loop to record the webcam by lapse of 10 minutes, is there a 
way to monitor the FPS and then stop and restart the command rather than 
waiting the remaining time (from the 10 minutes) ?

Alternatively, why would the FPS drops? Is there something to do to 
avoid it?

I use the following command to record the video.
ffmpeg -t 600 -f alsa -i pulse -acodec ac3 -f video4linux2 -s 960x720 -r 
15 -i /dev/video0 -vcodec mpeg4 -threads 0 cam_`date +%F_%T`.mkv

Should you require any further details, please do not hesitate to ask me,

Looking forward for your reply,

Regards,

Subject: [FFmpeg-user] q values and bitrate
Message-ID: <2A326DB2FB866B4C98676159D8A13001628ECB62@LNDWSMBX01.ad.mpc.local>

Hi there

<mailto:ffmpeg-user at ffmpeg.org>

I'm trying to encode MPEG2 files for broadcast. The spec is MPEG-2 @ 50Mbps with all frames as intra frames.


So I've done a few experiments and have come across a conundrum.


Setting the q flags like this:


ffmpeg -i input.%04d.dpx -vcodec mpeg2video -pix_fmt yuv422p -intra -qmin 1 -qscale 1 -output.mpg


gives a constant q=1.0 while transcoding and produces a file of approximately 25Mbps (although weirdly the file bitrate is given as: bitrate: 25551 kb/s while the actual stream is specified as 104857 kb/s. Is that the peak or just incorrect?)


Duration: 00:01:29.95, start: 1.000000, bitrate: 25551 kb/s


Stream #0.0[0x1e0]: Video: mpeg2video, yuv422p, 720x608 [PAR 608:405 DAR 16:9], 104857 kb/s, 25 fps, 25 tbr, 90k tbn, 50 tbc Stream #0.1[0x1c0]: Audio: mp2, 48000 Hz, 2 channels, s16, 384 kb/s



However, specifying a constant bit rate like this:


ffmpeg -i input.%04d.dpx -vcodec mpeg2video -pix_fmt yuv422p -intra -b 50000k -minrate 50000k -maxrate 50000k -bufsize 2000000 -output.mpg


gives a varying q whilst transcoding somewhere between 1 and 6. The resulting file is 50Mbps (in both the file and the video stream)



However, visually, the quality of this file is not as good as the 25Mbps (as suggested by the q factor), although it should be better I would have thought.


Unfortunately the files will be rejected by the broadcaster if they are not 50Mbps. So my question is how can I produce a file of 50Mbps AND q=1. It is my understanding that the q flags and the bitrate flags are mutually exclusive (I've tried running both).



Thanks very much for your help

Hello there,

I would guess your broadcaster wants not just any 50Mbps MPEG-2 file, I 
think he might want an D10 (or IMX) file. You might want to take a look 
at the FFMPEG Broadcast branch FFMBC. Otherwise there is a (little 
outdated but still useful) HowTo site for FFMPEG:

I've updated the patch to work with the latest ffmpeg version.

Here's the patch.

http://pastebin.com/5mTfGsdg

With this I was able to do:

$ cat *.png | ffmpeg -y -f image2pipe -r 60 -vcodec png -i - out.mp4

Subject: [FFmpeg-user] ffmpeg lightweight aac wrapper
Message-ID: <1336029881174-4605299.post@n4.nabble.com>

hey there!

I would like to write a simple wrapper interface for ffmpeg to use it only
for aac encoding.
I already compiled slim version of the ffmpeg, and worked my way through the
avcodec and avformat header files but I'm a bit lost.

The settings for the encoding will always stay the same, and the raw audio
input will also have the same meta data (sample rate, channels, bitrate
aso.). So what I want at the end is some sort of:

void openFile( char * filename ); //create/open file with header information
and initialize encoder/decoder
uint_8 *encode( uint_8 *data, int msec ); //encode real time into the
generated file and insert encoded stream at position msec (default = 0), and
return the encoded data
uint_8 *decode( int msecstart, int msecduration ); //decode the duration
from file at postion startpos

I would really appreciate some help on how to get there with the codec,
because I don't really know where to start right now.

Thanks in advance,
Roemer

Thanks for the reply!

I didn't manage to compile it in cygwin at the end. Even though I used
absolute paths like /cygwin/c/ the build process gets messed up with windows
paths (this seems to be a common problem with cygwin make)...

With some trying I managed to compile it under ubuntu, with the attached
android_build.sh at the end.

Maybe this helps some people out there.

I refer you to http://ffmpeg.org/ffmpeg.html#Stream-selection

and

I think you will find you need -map 0:a

I run FreeBSD 9.0. I install all dependencies (libraries) from ports
generally. The easiest way to do this is to go to the ffmpeg port,
configure it with the options you want, and install all dependent
libraries. (cd /usr/ports/multimedia/ffmpeg-devel && make config &&
make all-depends-list).

A couple of additional dependencies that may not come up in that list
- lang/gcc46, and the latest devel/binutils.

Once you have the dependencies installed, this is my build script for
building ffmpeg from git:

    cd ffmpeg
    git pull
    gmake distclean
    ./configure --as=/usr/local/bin/as --cc=/usr/local/bin/gcc46 \
        --extra-libs=-L/usr/local/lib --extra-cflags="-I/usr/local/include" \
        --prefix=/usr/local --mandir=/usr/local/man --disable-protocol=udp \
        --enable-postproc --enable-nonfree --enable-gpl --enable-version3 \
        --enable-libtheora --enable-libvorbis --enable-ffmpeg
--enable-ffplay --enable-ffprobe \
        && gmake -j 2

Hope that helps

Cheers

Tom

Thanks for your answer.

We also have to deliver IMX to some broadcasters, so I don't think this is the same spec.

I looked at this and picked out the MPEG-2 I-frame only Highest Quality Encoding settings on the same page.

I'll have a look at the IMX settings (they look fairly similar, but I'll investigate the additional flags)

Chris

Subject: [FFmpeg-user] Audio synchronisation issues
Message-ID: <CABhjJhOkcbrXJG8cDkvz0xty5nEaEAkmzVg001iSxan6Ap4WJQ@mail.gmail.com>

I am trying to record the screen, system sounds and microphone at the
same time, yet keep everything in sync. However, for some reason, it
doesn't work as it should, in that the length of the recorded streams
is the same, yet the audio and video are still out of sync (the desync
amount seems to change, but in an odd way, it starts desynced already
and gets either better or worse over time). This is what I use to
record my videos, without any special syncing:

/usr/bin/ffmpeg -xerror \
 -f x11grab -r 30 -s 800x600 -i :0.0+2,23 \
 -f pulse -i alsa_output.pci-0000_03_07.0.analog-stereo.monitor \
 -f pulse -i alsa_input.pci-0000_00_14.2.analog-stereo \
 -map 0 -vcodec mpeg4 -q:v 3 -qcomp 0.8 -threads 0 -an -timestamp now
-y Video.mp4 \
 -map 1 -threads 0 -vn -y AudioA.wav \
 -map 2 -threads 0 -vn -y AudioB.wav

Now I did try to fiddle around with -vsync and -async, but I don't
really understand how they work or when to use them. If I set the maps
to 0 1,0 2,0 and set async for both audio streams to 2, the recording
starts with very low framerates and eventually goes down to 0 FPS. If
I set maps to 0,1 1 2,1 and use vsync on the first stream (with either
of the modes) and async 2 on the last, it gets recorded correctly, but
I don't see any changes at all - the streams are still out of sync.
Interestingly enough, it seems that the audio streams are generally
well synced together, while the video stream seems to be
(inconsistently) in front by a second or so.

I also tried to use async in the processing, and not the recording
phase of production (are timestamps stored permanently in the video
and audio, so that this would be possible to begin with?), like this:

/usr/bin/ffmpeg -xerror  -i Video.mp4 \
 -i AudioA.wav \
 -i AudioB.wav \
 -map 0 -an -y VideoS.mp4 \
 -map 1,0 -async 2 -acodec libvorbis -threads 0 -y AudioAS.ogg \
 -map 2,0 -async 2 -acodec libvorbis -threads 0 -y AudioBS.ogg

...but it somehow produces audio that is unplayable (silent or just
refuses to play). Without the async parameter, everything gets played
fine. Not sure what could be the cause of that, either.

According to the task manager, my CPU is hardly utilised, so it can't
be a performance problem. So I'm not sure what causes the whole desync
in the first place... Any ideas about how to get the streams
synchronised?

     I figured out my problem.  I had tried the `%d' option earlier but it
wasn't working so I tried multiple files on the command line.  My `%d' tries
didn't work because my files are date/time stamped and are not a continuous
unbroken count of files.  I'm porting a script from another platform and that
script does change the file names to a continuous unbroken count of files, but
I hadn't tried running the script yet as I wanted to manually test the ffmpeg
command to make sure it would do what I wanted.  After I changed my script to
use ffmpet, it worked fine.  No ffmpeg errors or segfaults.  Thanks for
getting pointed back in the right direction.

Message-ID: <1336140409011-4608703.post@n4.nabble.com>

Hi,

I'm trying to add a RTMP live stream overlay to a video.

ffmpeg -i left_wide.flv -vf "movie=rtmp://url/app/stream:f=flv [mw];
[in][mv] overlay=640:0" combinedtest.flv

This worked well with another file (eg: right.flv) in place of the rtmp
stream but the colon (rtmp:) seem to logicaly cause an error :

[movie @ 00000000048006a0] Key '://url/app/stream:f' not found.
[movie @ 0000000001f100e0] Error parsing options string:
'://url/app/stream:f=flv'
Error initializing filter 'movie' with args 'rtmp:://url/app/stream:f=flv'
Error opening filters!

Any ideas on how to write this command line so it's correctly interpreted ?

How can audio and video be in sync (or out of sync) in a video-only 
or an audio-only file?

Complete, uncut console output missing.

Well, the way I record is that I need to have the three streams
separate, but have them be synchronised to each other so that I could
mix them into one video file later on. I need to apply some changes to
individual streams (like noise reduction and volume correction), hence
I need separate files for the streams initially.

Right, console output of the first command:

Why is --disable-protocol=udp necessary?
(Assuming there is a bug, did you report it?)
--enable-ffmpeg --enable-ffplay --enable-ffprobe should be unneeded, 
--enable-nonfree --enable-version3 has no (positive) 
effect in your configure line afaict

(Why, this should work exactly as well with a muxed file, don't you agree? 
And at least in theory, this may have higher chances of being in sync.)

The start times are similar on my system, and I get A/V sync with 
-async 1, but I suspect it is not possible with one device wall clock 
and one device starting with 0.
(But I may of course be wrong!)

Consider following ticket #692.

Message-ID: <CAKHtS0+r98jN+k7o3uWY4wPnrE1C_VuhMcu6rE1yWkHeAXRWfw@mail.gmail.com>

Hello All,

I'm trying to use the drawtext filter to render multiple lines of text on a
video, but the lines come out spaced too closely together, in fact the
spacing seems to be zero. Is anyone aware of a way to control the line
spacing with this filter?

You can see what I mean by running this experiment and looking at the
results:

$ cat /tmp/txt
LINE ONE
LINE TWO

$ ffmpeg -i BigBuckBunny_512kb.mp4 -an -vcodec libx264 -preset fast -vf
"drawtext=fontfile=/usr/share/fonts/truetype/msttcorefonts/Arial_Bold.ttf:
textfile=/tmp/txt: x=2*max_glyph_w:y=0.85*h-line_h" -t 10 -f mp4 -y out.mp4

Schuyler

I'm using SoX to modify the audio on a per-stream basis (I don't want
to remove noise from the track that has no noise, after all), and I'm
not aware of it being able to modify a particular stream within a
video file (plus it would have to be remuxed so that there is only one
video and one audio stream for it to be played correctly). That said,
I could record everything into one file and then use ffmpeg with copy
to extract the separate streams after that.

I did some further testing, and it's somewhat confusing. I did get the
audio and video synced correctly, but only if recording only two
streams, not all three. I noticed that it gets desynced when I get
dropped frames (or duplicate frames, which appear as dropped frames in
the video regardless). I get these dropped frames when I record all
three streams, but not when recording only two. Also, putting the
video recording to the last position makes less duplicate frames and
more dropped frames reported, for some odd reason. It also doesn't
seem to matter whether the streams are output to a single file or
multiple files (as async doesn't seem to do much, anyway, at least
when I don't specifically specify what to sync to via maps). And
apparently when the two audio streams come from the same sound card,
the framerate improves (although I don't get why it drops in the first
place...).

The really puzzling part of this is that if I add around 1 second of
blank frames into the recording with 3 streams, everything seems to
get synced properly again. That said, I haven't tested long
recordings, so I'm not certain if it doesn't get desynced again after
a while... I'll have to do further tests, it seems.

Hmm, true, that does look kind of odd. I wonder what causes that kind
of a discrepancy.

Please post _full_, _uncut_ and _unmodified_ command line and its
output of _recent_ ffmpeg version from _ffmpeg.org_ here. Your logs
seem to be strangely modified. And you used libav.org version, which
is not supported by ffmpeg.org. And your second log is cutted.
Generally publishing to RTMP server is possible. You can even try it
without librtmp support, ffmpeg has internal rtmp protocol
implementation.

Currently there's no such parameter. Patch is welcome.
As a workaround, you may pass source video through two separate
drawtext filters, writing single line per filter instance.

Subject: [FFmpeg-user] UDP FEC Protocol?
Message-ID: <4FA458B2.6040706@ponzo.net>

Hello,

Recently heard a company was working on FEC for their streaming.  He 
also said they were building it as a proprietary system, so I guess 
they'll have it, and we won't.

But I assume FEC means a UDP-based streaming protocol.  Do we know of 
any such thing existing currently?

This has me intrigued.  Using the error counts coming out of the fec 
"layer" in a udp stream, maybe one could implement congestion avoidance, 
and downshift the bitrate of the stream dynamically.

So -- is there a streaming protocol that is udp/fec, potentially 
congestion-avoidant, and can be used for abr?

Thanks,

  -Scott

Hi everyone, I have search along the forum for answers on this question and
didn't get clarified about it.

I have a mjpeg video already in memory and I want to decode it directly from
memory. Anyone is familiar with a routine to open from buffer like
avformat_open_input() opens from a file?

Best regards,

Subject: [FFmpeg-user] Question about v4l2 controls and ffmpeg,
	also dts muxer problems
Message-ID: <4FA45C4F.5030703@gmail.com>

Hi!

I am currently trying to record two video streams with a script from two
webcams with ffmpeg. This works relatively well.

I am using the following command (with an adjusted -i /dev/videoX and
output file, of course):

ffmpeg -f video4linux2 -framerate 30 -video_size hd720 -input_format
mjpeg -fflags igndts -an -i /dev/video0 -c:v copy -an /HDD2/test1.mjpeg

I am curious though if there is any way of controlling the v4l2 control
ids through ffmpeg, i.e. things like V4L2_CID_WHITE_BALANCE_TEMPERATURE,
V4L2_CID_DO_WHITE_BALANCE, V4L2_CID_FOCUS_AUTO ...
The autofocus particularly kicks in during recording and messes things up.

I also have another problem, namely that I am getting tons of errors
"/Application provided invalid, non monotonically //increasing dts to muxer"
/
I tried using "-fflags igndts" and "-an" but that does not seem to
change anything. If I tell it to save it as an .avi file it crashes
immediately, with the mjpeg it seems to record relatively OK. Is there a
way of solving this? Or, at the least, to turn off the error messages?

Thanks for your help - and for this awesome tool!
Goetz

No, but I believe it should be straight-forward to implement, see 
v4l2_set_parameters() and options[] in libavdevice/v4l2.c

I played a bit more with this - some observations.

I can reproduce on Fedora 15 so it's not just my setup.

I see that ffmpeg git is not very bisectable - but this shows me that 
this problem doesn't happen with avconv which gets built depending on 
which commit is landed on.

I went back to October manually choosing the merge commits so ffmpeg 
built and couldn't find one that worked.

Hello,

Excuse me in advance for my bad english ...

What is the real difference between the command: ffmpeg -formats and
the command: ffmpeg -codecs ?

In the application I'm developing detection capabilities of FFmpeg is
not good (in which he's capable of transcoding in a particular menu).
I made a Python script detection, one based on: ffmpeg -formats
(Ubuntu 12.04), that is what it returns:

rem_doubles ['m4v', 'raw', 'dnxhd', 'smjpeg', 'null', 'mjpeg',
'cavsvideo', 'vcd', 'EG-2', 'svcd', 'eac3', 'ac3', 'mpeg2video',
'truehd', 'mpeg1video', 'h264', 'h261', 'h263', 'flac', 'RoQ', 'ogg',
'dirac', 'dvd', 'g722', 'flv', 'mlp', 'dts']

diff ['libxvid']

codec_fautif [[7, 'libxvid', 'Xvid (avi)', '--enable-libxvid', 'avi']]

Only libxvid is not detected (the variable diff tells us, the returned
data is in the form of a list).

In either case (using the command: ffmpeg-codecs) is completely
different (tests done on openSUSE 12.1):

rem_doubles ['mjpeg', 'EVSD', 'dvd', 'flv', 'raw', 'libxvid', 'EDraw', 'ES']

diff ['h264', 'svcd', 'vcd', 'ogg']

codec_fautif [[1, 'vcd', 'VCD', '', 'mpg'], [2, 'svcd', 'SVCD', '',
'mpg'], [5, 'ogg', 'Theora (ogg)', '--enable-libtheora', 'ogg'], [8,
'h264', 'H264 (avi)', '--enable-libx264', 'avi']]

Here there is a lot things that are not detected: h264, svcd, vcd,
ogg, here the libxvid is detected.. Again the vaiable diff tells us,
the data are returned as a list.

What do I use the command: ffmpeg-formats or command: ffmpeg-codecs ?

A report with the version of FFmpeg installed on Ubuntu 10.04 (the old
LTS), the command: ffmpeg -codecs does not exist (there is only the
command: ffmpeg -formats).

Is this only reproducible with an external library and -acodec copy or 
also if you use -an and an internal encoder?

(git bisect works fine here for all kinds of bugs, but if I can 
reproduce the issue I can do it.)

ffmpeg -formats lists the available (input- and output-) formats 
(avi, matroska, asf, ogg, transport stream, program stream etc.), 
ffmpeg -codecs lists the available (input- and output-) codecs 
(MPEG-1 Video, H263, native MPEG-4 ASP, realvideo x, libxvid, 
libx264 etc.), they are two independent things.

OK, I tried as below and still failed  - this time avi, mkv also fails 
but produces a lot of noise with the loglevel.

m2ts doesn't fail.

One observation, though testing with -an probably means it doesn't 
matter, is that the working cases I've found - avconv and m2ts both DUP 
40 ish frames at the start - I assume to sync sound.

'ffmpeg -formats' lists the containers supported by that build of 
ffmpeg. A container holds one or more 'streams' (also called 'tracks'), 
and a container typically has synchronization information (timestamps) 
for each track.

'ffmpeg -codecs' lists the elementary stream codecs (encoder or decoder) 
supported by that build of ffmpeg. A 'codec' converts between the 
compressed and uncompressed representations (video or audio or whatever).

I'm new to FFmpeg. I got a demo program to compile successfully but is 

crashing when av_mallocz() is invoked. I switched it up with av_malloc() 

but still crashes. I wanted to use standard malloc(), which doesn't crash, but
there might be problems with alignment and such.

I'm not sure how mailing lists work so I hope I'm doing this right.

Thanks, that's the way I've been hacking the solution, but it's a bit 
cumbersome beyond a couple of lines. I'll look into what it would 
take to patch the filter.

not entirely clear what this would entail. Since I am not a programmer,

Do I need to compile ffmpeg to get the ffmpeg_g? Here is what I get in the

Subject: [FFmpeg-user] Avoid yadif auto format for progressive bgra
Message-ID: <CALdTkGESxEWK==FQQjbhfQ6tYfWhSqNZJMrr3_e57-Rj7Jy1Gw@mail.gmail.com>

I have a problem with yadif where a progressive bgra video stream is
converted to yadif supported formats even though yadif does not do anything
to the stream (auto_enable==true).

My question is whether I can solve this using a split and some form of
"conditional" filter? e.g.

                      /-> if interlaced   -> auto-format -> yadif ->\
source->split ->
 -> merge -> sink
                      \-> if progressive ->                              ->/

Is this possible? And will it work as I assume it would? I guess it would
not work for streams with both interlaced and progressive frames, but does
such stream exist?

I have not used it, but I looked at UDT a few years ago.  Maybe it will 
suit your needs?

Subject: [FFmpeg-user] How can I add a header to an HTTP Post from the
	command line?
Message-ID: <CAMBtMcsnjc78VsqnS-q1nXGFhm9Tfm2y8HP2f992ow7-c_B4Zg@mail.gmail.com>

A URL may be used as an output file (or output file sequence) and this
works fine for me:

   ffmpeg -i input ...  http://output/path

The source code leads me to believe that certain options (like user-agent)
can be changed from the command line, or that arbitrary HTTP headers can be
added with a "-headers" flag.  I have tried things liks:

  ffmpeg -i input ... http://output/path -user-agent "my-own-agent"

However, I have not been able to figure out how to make command line
options have any effect on HTTP POST output files.

Any help would be appreciated, including information that this is not
supposed to work.  P.S. - I am using version 0.10.2.

Thanks. Tom

I would hazard a guess that in order for YADIF to decide to do nothing
it has to be able to understand the stream first.

In terms of flagging hopefully not. In terms of content, often. Which
begs the question, how do you determine the whether or not material is
interlaced or not?

The idet filter makes a good stab at content based analysis *but* it
doesn't work on bgra sources as it auto inserts a scale 0 filter to
convert to YUV first and any auto inserted filter seems to stuff its
analysis.

Or do you trust the interlace flag. this requires that material is both
flagged correctly by the coding system, *and* the flag is correctly
interpreted by ffmpeg. Currently results suggest that this is not nearly
good enough to be relied upon.

For my inputs it seems the interlace flag is good enough, I query
it with:

mediainfo --Inform="Video;%ScanType%"

Is there a similar command for ffprobe?

There was a bug, I never reported it - I think it was a linuxism. It's
gone now, regardless - no problem with libavformat/udp.c now.

Nope, I think it was something simple like not including ctypes.h. I
didn't need udp at the time, so simply disabled it - I hadn't noticed
until you pointed it out I still had it disabled!

Message-ID: <20120508142220.GA8525@corky.vhb>

I think this is a basic syntax problem, but I could be missing
it.  I have a short clip from the movie Tron:Legacy in 3D ripped
from the HD 3D Blueray.  The audio appears to be 5.1(side) DTS ?
though, I have reason to suspect it's really 7.1 ...

Anyway, the downmix audio is effing horrible.  I wanted to look
at each channel individually and see if I couldn't come up with a
game plan for a downmix before I switch to non-ffmpeg tools for
the job.  That's when I noticed my pan= filters were not doing
anything.

I expect I'm missing something simple.  I tried putting -ac 1
before the filter and I tried omitting it entirely.  Changing the
argument order seems to have no effect.  Removing -ac 1 causes an
output error, since (I think) mp3s can't have 6 channels.


for i in c{0..5}; do
    ffmpeg -i short.mkv -strict experimental -filter:a pan=1:c0=$i -ac 1 -y $i.mp3;
done

Complete, uncut console output missing.
But please decide if you want to use pan or -ac 1 since -ac 1 
makes sure the dts decoder outputs mono (which cannot be 
changed by pan in any way).

I don't understand what this means and the docs are unclear on
the implications of using -filter:a with -ac.  If I leave off -ac
1 and try to use (eg) -filter:a aconvert=stereo:pan=blarg then
ffmpeg tries to stuff 5.1 audio into an mp3, which doesn't work.

This is actually what I want.  I thought the for loop made it
clear that I'm trying to put each channel in its own file.  If
this is not clear from the for loop then there's obviously
something wrong with my syntax and my understanding of how this
program operates.

Audio filtering is not yet supported in the ffmpeg command line tool, you
need to use workarounds to use it:

ffmpeg -f lavfi -i amovie=short.mkv,pan=1:c0=$i

The -strict experimental seems strange.

This is really interesting and probably explains everything.
It's funny that the man pages clearly indicate these filters
exist and ffmpeg produces no errors when you try to use them.

> The -strict experimental seems strange.

Not *that* strange I hope.  I'm arch, so everything is bleeding
new.  This channel spliting is yak shaving and -strict
experimental is vestigial, relating to my actual transcode
project where the output has an aac audio stream.  Without strict
experimental I get this:

I am surprised an error is not produced.

This is expected. To you really want to use an unfinished encoder that
produces possibly broken streams or at least very poor quality ones?

Normal users should not use -strict experimental.

Subject: [FFmpeg-user] writing output via image2 to stdout
Message-ID: <005c01cd2d61$2e5da8a0$8b18f9e0$@afkbio.de>

I am using ffmpeg to exctract single images from a video, at the rate of one image per second.
Per default I have to specify an output format like img-%03d.jpeg and the images will get written to disk one by one.

I am calling ffmpeg from within another program, so ffmpeg writes the images to disk and my application reads them afterwards.
However I'd love to be able to grab the results directly from stdout to process them further but FFMPEG won't let me do this:

The first image is returned via stdout and when it comes to processing the second one it errors out with 
>[image2 @ 00000000043100A0] Could not get frame filename number 2 from pattern 'pipe:'

Is there any workaround for this (if yes, how would I know where to split the datastream in separate imaghes?) Is there any other possibility how I can transfer the ffmpeg output directly to my application without having to write on disk?

Thanks!

Subject: [FFmpeg-user] ffserver rtsp streaming
Message-ID: <1336468221186-4616971.post@n4.nabble.com>

Hi I've successfully setup a streaming server to stream live video from my 
webcam using ffserver. 
I've been able to stream it using asf and flash, and it is working pretty 
well. 

I just have a small delay problem (around 5 secs), but the reason could be 
that I'm using a really old laptop as streaming server. 

Anyway, what I really need right now is to stream using rtp/rtsp, my config 
file looks like this: 

Port 8090 
# 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 
</Feed> 

<Stream test.asf> 
Format rtp 
Feed feed1.ffm 
VideoCodec flv 
# this must match the ffmpeg -r argument 
VideoFrameRate 15 
# generally leave this is a large number 
VideoBufferSize 80000 
# another quality tweak 
VideoBitRate 200 
# quality ranges - 1-31 (1 = best, 31 = worst) 
VideoQMin 1 
VideoQMax 5 
VideoSize 160x128 
# this sets how many seconds in past to start 
PreRoll 0 
# wecams don't have audio 
Noaudio 
</Stream> 


then I use ffmpeg to get the video from my camera with this command: 
ffmpeg -s 160x128 -f video4linux -i /dev/video0 -r 15 
http://localhost:8090/feed1.ffm

Then it starts encoding without problems. 

Still when I go to VLC or Totem and open rtsp://localhost:8090/test.asf on 
the server, I'm unable to watch the stream. 

I would like to know if anyone has experience doing streaming over rtp with 
ffserver, and how can i make it work 

thx

Thank you so much for your useful info. I also want to present one awesome
program which converts mp4 videos and mp3 files quickly and without quality
loss. You can  http://www.soundtaxi.info/mp4-to-mp3.html try for free  on
the official website.

Subject: [FFmpeg-user] Streaming to Flash Media Server
Message-ID: <CADBW8UYVPfubt=EeR11mcdhffX0DQ_=XEErhq5dNG-YmE9=_4g@mail.gmail.com>

Hello,

I've been trying to set up ffmpeg to stream from a live DirectShow capture
device to a Flash Media Server instance hosted on Amazon AWS. For some
reason I keep getting error messages like "real-time buffer 101% full!
frame dropped!" and very few frames actually get encoded. I have included
the command I'm using along with some sample output below. It works fine if
I save the output to a file instead of streaming it (i.e. by replacing
"rtmp://..." with "test.flv", for example), so I think that the issue is
with the streaming, not the encoding. The PC has a fairly powerful CPU that
should be able to handle the encoding and streaming without any problems
(Adobe's Flash Media Live Encoder works fine). One thing I noticed when
encoding to a file is that the bitrate is in the thousands of kbps, even
though I've specified a video bitrate of 500k and an audio bitrate of 128k.
How do I keep the bitrate reasonable?

I am new to both Flash Media Server and ffmpeg, so after spending quite a
few hours trying to get this to work I'll admit that I'm completely stuck.
Does anyone have any suggestions as to what I'm doing wrong or what other
parameters/options I should try? They would be very much appreciated!

Jonathan

Did you try -f image2pipe ?

In case this isn't absolutely obvious:
Since you specify these options *after* the output "file" (rtmp...), 
they have no effect because options have to be put in front of the 
stream / file they are intended to change.

Did you test with a very small frame rate to make sure this is not a 
performance issue?

Message-ID: <3B57891A-013D-46D0-B074-0F817D9F915A@dominicansinteractive.com>

I am using FFMPEG 10.2 to segment video files.
Currently (with 10.2) I encode the files first to a .ts encoded file and then copy it with the -segment options. This works great for video files, but when trying to do it for an audio-only file I end up with one big file instead of separate segments. The command I use is:

ffmpeg -i encoded.ts -y -c copy -flags global_header -map 0 -f segment -segment_time 10 -segment_list fileList.txt -segment_format mpegts segment_%05d.ts

I also tried to use the MP3 encoder instead of mpegts, but it makes no difference.
Is there a way to get this to work?
Thanks!

Which of course makes soundtaxi a software that cannot be legally

No surprise here, Carl Eugen

Thanks, great.
Is there a specific button to be added to the CC? I created an account an logged in, but I don't see a way to add myself to the CC field (luuk_jansen).

Subject: [FFmpeg-user] how to restore a video file I just overwrote?
Message-ID: <BAY154-W90910B35DF3DD45EAC7E9C3110@phx.gbl>


Hello,

I made the big mistake of forgetting the "-i" in the next command and validated the "overwrite?" warning a bit to quickly.
ffmpeg -i V_0003.MP4 -ss 0:00:41 -t 0:01:00 short.mp4

It obviously replaced my very important V_0003.MP4 video, for which I have no backup, with a useless 0kb video file with the same name. Stupid of me but, sure.

Is there any way I can find this video back? It's located on an external USB (NTFS) drive, It's quite big (1.1Gb). I made no write to the drive after my mistake. Undelete did (obviously) not find the file as it had not been deleted... but most of its content should still be there (unless maybe the header... but even then, who am I to know). It should even be located quite straigtforwardly as this disk is mostly used for external backup purposes (not many delete operations)

Any hint would be warmly appreciated, even more if it works under linux... but free alternatives with windows I welcome too.

Thanks in advance.
Berteh.


PS: and thanks to the developpers of ffmpeg, which has proven very useful in various situations!

Undelete did (obviously) not find the file as it had not been deleted... but most of its content should still be there (unless maybe the header... but even then, who am I to know). It should even be located quite straigtforwardly as this disk is mostly used for external backup purposes (not many delete operations)

I'd recommend looking at photorec or (if not that) testdisk at http://www.cgsecurity.org/wiki/PhotoRec. Photorec supports MP4 containers. Be sure to prevent any further write actions to the drive while you work on the recovery.

Hello,

In newer versions of ffmpeg command:

ffmpeg -version

... no longer shows the lines: --enable-someone. This example which is
shown in FFmpeg on openSUSE 12.1 (this is the same thing it seems to
me in FFmpeg on Ubuntu 12.04):

Is there a command to read the lines --enable-someone in new versions

Your post is rather interesting! I also am interested in live streaming as
well, but only audio!
Take a look at this website:

http://prupert.co.uk/2010/08/02/stream-live-audio-from-a-microphone-in-near-real-time-in-ubuntu/

You will find int very informative! If anybody can share with with how I
can stream live audio in two channel stereo, I would appreciate a
reply. Currently ffmpeg along with vlc allows audio streaming in one
channel only! Here is the potential command:

ffmpeg -f oss -i /dev/dsp -acodec libmp3lame -ab 32k -ac 1 -re -f rtp rtp://
234.5.5.5:1234

If anyone can expand on this command do so!

Subject: [FFmpeg-user] How to get good x264 compression?
Message-ID: <1336586737941-4621261.post@n4.nabble.com>

Several years ago, I started editing HD video from the Flip video camera down
to a lower (but still HD) resolution to save space.  This invocation worked
well and gave good conversion results -- no significant degradation of
quality:

    ffmpeg -threads 2 -i "$ORIG" -s hd480 -vcodec libx264 -acodec copy
"$NEW"

When I try that with my current version of ffmpeg (FFmpeg version
0.6.4-4:0.6.4-0ubuntu0.11.04.1, Copyright (c) 2000-2010 the Libav developers
built on Jan  4 2012 16:13:16 with gcc 4.5.2), I get:

    [libx264 @ 0x1213e20]broken ffmpeg default settings detected
    [libx264 @ 0x1213e20]use an encoding preset (vpre)

I've tried using presets:

   ffmpeg -i HBC_Baptisms_Spring2012_10_ClosingComments.MP4 -s hd480 -vcodec
libx264 -vpre   normal -acodec copy  -threads 0 -y
HBC_Baptisms_Spring2012_10_ClosingComments.hd480.MP4


   ffmpeg -i HBC_Baptisms_Spring2012_10_ClosingComments.MP4 -an -s hd480
-vcodec libx264 -vpre    slow_firstpass -pass 1 -threads 0 -f mp4 -y
/dev/null  && ffmpeg -i HBC_Baptisms_Spring2012_10_ClosingComments.MP4 -s
hd480 -vcodec libx264 -vpre slow -acodec copy -pass 2 -threads 0 -y
HBC_Baptisms_Spring2012_10_ClosingComments.hd480.MP4

But every thing I've tried has given highly degraded results -- nothing like
the clean results I used to get. 

What am I missing?

This doesn't look like FFmpeg. It's most likely the fork. You should
upgrade to FFmpeg (http://ffmpeg.org/download.html). This behaviour has
changed only in the fork.

This is very ancient and therefore not supported,

This is not only ancient, but also unsupported because it is not FFmpeg.

Please see http://ffmpeg.org/download.html - current git head 
is always recommended.

I was recently capturing DVB-T TS streams (individual programs) to files and
when I use ffplay to watch them (Windows 7 SP1 x64, ffmpeg x64 static build,
available from http://ffmpeg.zeranoe.com/builds/ built at 05 May 2012) it
always crashes.
According to some TS analyzers the files didn't have any problem so I keep
trying other builds of ffmpeg until I found out that ffmpeg x86 shared build
(from the same day) can play those files without any problem.
Hope this information is useful for anybody.

Sorry about that.  Not until I went to investigate what you meant by "not
FFmpeg" had I heard about the fork and all the associated ugliness before
and after.

I'll redirect my query to the LibAV folks.

Folks,

I need to set up a process to encode a bunch of static images into an mp4 file.

Let's say I have two machines that are almost identical in hardware, OS, ffmpeg, etc. The only difference is that one machine has a slower CPU than the other. For the same input to ffmpeg, will the output be identical on both machines?

I understand that the encoding will take a longer time on the slower machine. I am just wondering if there is any timing involved during encoding that may result in lesser quality output on the slower machine.

Thank you in advance for your help.

Regards,
Peter

That, as they say, is a matter of opinion.

It's unrealistic to expect everyone who usese the thing to be fully aware  
of all the ridiculous opensource politics that goes with it. If you wish  
to claim that something is "not ffmpeg" I would suggest that it should be  
proven in a court of law, as anyone else would with a naming dispute.

Until that step has been taken, please accept that not everyone is in a  
position to use "current git head".

This is not exactly true.

Not only do FFmpeg developers explain repeatedly that this 
intentionally broken fork of FFmpeg with its several hundred 
regression cannot be supported here (and is not FFmpeg), 
the people who tried to steal FFmpeg also insist that they 
are not developing FFmpeg anymore.

Subject: [FFmpeg-user] ffmpeg RTSP (No JPEG data found in image)
Message-ID: <4FAB80C1.2040809@sacnet.es>


Please I need to catch jpeg frames from a mjpeg video streamed under 
rtsp, in port 665.
The size and port are correct but I'm not quite sure all parameters are 
correct.

When running the command:

ffmpeg -i rtsp://192.168.xx.xx:665 -vcodec mjpeg -s 704x576 -f image2 
file-%03d.jpg

I get these errors:

[mjpeg @ 0x947bb00] No JPEG data found in image
[mjpeg @ 0x947bb00] Found EOI before any SOF, ignoring
[mjpeg @ 0x947bb00] No JPEG data found in image
^Cdecoding for stream 0 failed
[rtsp @ 0x9473aa0] Could not find codec parameters (Video: mjpeg)
[rtsp @ 0x9473aa0] Estimating duration from bitrate, this may be inaccurate
rtsp://192.168.101.141:665: could not find codec parameters


The build info is the next:

root at xxx:~# ffmpeg
ffmpeg version 0.10.3 Copyright (c) 2000-2012 the FFmpeg developers
   built on May  9 2012 17:44:24 with gcc 4.4.5
   configuration: --prefix=/usr --enable-runtime-cpudetect 
--enable-hardcoded-tables --enable-libx264 --enable-zlib --enable-shared 
--enable-gpl --enable-decoder=h264 --enable-decoder=mjpeg 
--enable-network --enable-protocol=tcp --enable-demuxer=rtsp 
--enable-decoder=h264 --enable-libopenjpeg --disable-debug


Also say that ffmpeg plays perfectly the mjpeg video if it receives the 
input piped from openRTSP like this:

openRTSP -c -t -v rtsp://192.168.101.141:665 | ffmpeg -f mjpeg -i - -f 
image2 fichero-%03d.jpeg

Therefore I can guess I'm missing any parameter to help ffmpeg  to 
manage the rtsp stream, I can not use the piping method because is for a 
openCV aplication.

But if the input video contains 2 audio tracks and if I don't use map
option, shouldn't ffmpeg copy all the tracks to output by default. But I
observed By default it copies one audio and one video stream. If I am
correct, what is the rule behind copying audio tracks in output video

Actually This option is for audio not, so its obvious that you won't get
any audio stream in output.
I suggest try -acodec copy, if you dont want any transcoding to happen with
audio stream, hence saving time

Please don't top post.

ffmpeg comes with a manual that explains how to use it. The third
paragraph says:

Each input or output file can in principle contain any number of
streams of different types (video/audio/subtitle/attachment/data).
Allowed number and/or types of streams can be limited by the container
format. Selecting, which streams from which inputs go into output, is
done either automatically or with the "-map" option (see the Stream
selection chapter).

The 'Stream selection' chapter says:

By default ffmpeg includes only one stream of each type (video, audio,
subtitle) present in the input files and adds them to each output file.
It picks the "best" of each based upon the following criteria; for
video it is the stream with the highest resolution, for audio the
stream with the most channels, for subtitle it's the first subtitle
stream. In the case where several streams of the same type rate
equally, the lowest numbered stream is chosen.

You can disable some of those defaults by using "-vn/-an/-sn" options.
For full manual control, use the "-map" option, which disables the
defaults just described.


Cheers

Tom

Please don't top post.

I think the OP's point was that if he is doing 2-pass x264 encoding,
on the first pass he doesn't want to do anything with the audio, just
discard it, and re-encode it/copy it on the second pass, but when he
tries this he ends up with no audio in the second pass.

Of course, he neglected to show command lines or output for either of
the passes, so that is utter speculation.

I've got a bunch of video captured from analog sources, it includes
regions of pure noise.

How do I stop the underun errors during these times.

If I don't set  a maxrate then the resulting file exceeds the allowable
peak rate during the noise patches.

If I do set a maxrate & legit bufsize it under-runs.

Either way modest DVD players seem to spit the dummy... well mine at
least.

I need to allow it to do a crap job of the crap input but I don't seem
to be able to find the appropriate incantations.

This is 
  ffmpeg version 0.8.10, Copyright (c) 2000-2011 the FFmpeg developers

ffmpeg -i  blarg.mov -an -vf gradfun,hqdn3d -r 25 -lmin 1 -b 6000k

This did indeed the trick, thanks!
This should be added to the documentation at http://ffmpeg.org/ffmpeg.html

Subject: [FFmpeg-user] Variable frame rate videos
Message-ID: <COL124-W7E3D53FEC97E251FEFAC994160@phx.gbl>


Hi!

I need to use FFMPEG to write an application to record a movie out of an MJPEG camera stream.
I've looked on some exemples of the API, but I've a question, how do I make variable-length frame rates?

On one of the examples, there is:

00277         out_size = avcodec_encode_video(c, outbuf, outbuf_size, picture);
00278         printf("encoding frame %3d (size=%5d)\n", i, out_size);
00279         fwrite(outbuf, 1, out_size, f);
Would it work as I expect if I changed c->time_base?



Thank you very much!

Subject: [FFmpeg-user] Compiling FFMPEG on the Mac,
	issue with configure and vorbis libs...
Message-ID: <4FAAF5B0.4080708@gmail.com>

I'm nearly done getting FFMPEG ready to compile - however, it is not 
finding the Vorbis libs, which are clearly installed.   I have tried 
setting CFLAGS and LDFLAGS to include /usr/local/lib and 
/usr/local/include which has had no effect.

I tried commenting out the require line in the configure script, to see 
if that might just work and it did not.

The C compiler is set to "clang".

What is wrong?


Thanks....


Here are the config directives:

export LDFLAGS="-L/usr/local/lib"
export CFLAGS="-I/usr/local/include"

./configure --prefix=/usr/local --enable-gpl --enable-version3 
--enable-nonfree --enable-libx264 --enable-libxvid --enable-shared 
--enable-postproc --enable-swscale --enable-avfilter --enable-pthreads 
--enable-yasm --enable-libfaac --enable-libmp3lame --enable-libvorbis 
--enable-libvpx
???????????????????????????

The error:

ERROR: libvorbis 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.


But, yet it is clearly there......

Hey, 
Has anyone successful compiled ffmpeg with the new Xcode 4.2/iOS SDK 5.0?

MACOS 10.7.3

./configure --disable-doc --disable-ffmpeg --disable-ffplay --disable-ffserver --enable-cross-compile --arch=arm --target-os=darwin --cc=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc --as='gas-preprocessor/gas-preprocessor.pl /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc' --sysroot=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk --cpu=cortex-a8 --extra-cflags='-arch armv7' --extra-ldflags='-arch armv7' --enable-pic


/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc is unable to create an executable file.
C compiler test failed.



Thanks

your card may require crossbar connecting, which ffmpeg doesn't do yet.

Subject: [FFmpeg-user] Wrong input framerate detected
Message-ID: <CA+-ctj5wN05g2aepshy6EQ3z_w4CxYzariL9WfGzXavBsCfxsA@mail.gmail.com>

Hi,

It seems that ffmpeg is incorrectly detecting the input framerate of a
video I have.

My encode attempt utilized the concat protocol. Just to demonstrate the
framerate, I have the following stripped down to just the input.

$ /cygdrive/c/ffmpeg/bin/ffmpeg -i

Message-ID: <104556F9-83C3-4D5F-93FB-6AB7C0E61F15@earthlink.net>

Hi. So far I've installed x264 and it is in my path, but when I try to build:

./configure --enable-libx264 --enable-gpl --enable-pthreads --disable-ffplay --disable-ffserver --disable-shared --arch=x86_64 --enable-debug

I get:

ERROR: libx264 not found

I also tried with 

./configure --enable-libx264 --libdir='~/x264/' --enable-gpl --enable-pthreads --disable-ffplay --disable-ffserver --disable-shared --arch=x86_64 --enable-debug

but I'm not sure of that syntax for the libdir.

Can someone help me get this sorted?

Hi Joel,

did you compile x264 from source?

I usually use --extra-cflags=-I/opt/local/include and --extra-ldflags=-L/opt/local/lib but the path depends on your used prefixes, maybe you have to use /usr/local instead of /opt/local.

Best,
Ren?

Hi All,

Please let me know what is the difference between audio track and audio
stream. Are both same or different?
Can one audio stream contain several audio tracks.

Message-ID: <1336723086.12525.YahooMailNeo@web125403.mail.ne1.yahoo.com>



Folks,

I have to process some static images into an mp4 video. An article on the internet mentions that, before running ffmpeg/avconv, it is better to run "convert" utility from ImageMagick and create morphed images. The next step would be to run the morphed images through ffmpeg.

I am wondering if this step is really necessary. Isn't it the job of the libx264 encoder to do this anyway?

Thank you in advance for your help.

Regards,
Peter

may be what you want to ask is Audio Track vs Audio Channel, since Audio
Track n Audio Stream is the same thing.

one video file can have multiple audio track, and inside an audio track,
there is multiple audio channel with a preset configuration, be it a mono,
stereo, surround, etc.

on a video file with multiple track, each track usually have different
purpose, e.g. as a suplementary language, commentary, etc. each track can
have different configuration of channel, sampling rate, or bitrate.

Mediainfo does not tell the whole story, and is not doing the same 
calculation that ffmpeg does.

For ffmpeg, I believe that the 'fps' value is the average framerate of 
the beginning of the video. If ffmpeg can't get the info from the file 
header, ffmpeg evaluates a few hundred frames to calculate this.

If the movie is a mix of 23.97 frame/sec material and 29.97 frame/sec 
material, 26.69 is a reasonable number for an average value.

Look up the word "telecine" if you care to understand this better.

The word "stream" is commonly used both ways. Hopefully, the other words 
around it will make clear which meaning is intended.

FFmpeg has no morphing filter (yet), patch welcome.

(--disable-shared --enable-pthreads should not be needed, I 
never understood why --arch should be needed, I never need 
it, and I wonder if --enable-debug is really what you want.)

Probably, if you post the last lines of config.log

Why do you think so?
Is there a problem with A/V sync? If yes, please provide command 
line together with complete, uncut console output and a sample.
(No external libraries if they are not needed to reproduce 
the problem.)

> My encode attempt utilized the concat protocol. 

Is there only a problem if you use concat: or also if you encode 
a single input file?

> Just to demonstrate the

Or do I misunderstand, encoding runs fine (and the encoded file 
is fine), but you don't like FFmpeg's console output?

(Please note that I do not easily remember a problem where 
MediaInfo was any help.)

Please post all necessary information here on the mailing list, do 
not use external resources (they may disappear).

If you want to report a compiling problem, please run make, run make 
again, then run "make V=1" and post the complete output of the last 
run here, please do never post the complete, uncut output of the 
first make run.

My media player (and mediainfo) indicated it as such; you'll have to
forgive my lack of knowledge per Mike's response.

No problem with concat, I was only showing it for reference with the other
info in case it meant something useful. I now know from Mike's response
that it does not; again, lack of knowledge with regard to his feedback.

Hi Mike,

Thank you for the response. I am definitely interested in understanding
this better so will most certainly look up info about "telecine" when I
have a chance later.

Without the knowledge of the aforementioned "telecine" and it's
consequences, am I to presume ffmpeg handles this fine? Is there anything
additional I must do for the encode or any advice that would be helpful
here?

Or, should I be saving these questions until after I've gotten the chance
to do some research? :)

Thanks,
Brendan

Hi,
I am trying out ffmpeg for the first time. I am not able to run the
"configure" script.
It quits saying :

"If gcc is a cross-compiler, use the --enable-cross-compile option.
Only do this if you know what cross compiling means.
C compiler test failed."

Did i get something wrong?

I'm not sure if this is your problem.  I install on a Mac running 10.7.3.  I found out that libvorbis by default will configure itself for i386 architecture, so it won't match with ogg, which is set for x86_64.  I added --build=x86_64 to the libvorbis configure options, it worked.  

So my libvorbis install is:

./configure --prefix=${TARGET} --build=x86_64 --with-ogg-libraries=${TARGET}/lib --with-ogg-includes=/Volumes/Ramdisk/sw/include/ --enable-static --disable-shared --disable-oggtest && make -j 4 && make install;

It's a little strange because I install first on a Ramdisk.

The above line indicates that you are using "ffmpeg" (now called
"avconv") from a fork, and not ffmpeg from the FFmpeg project.
Obviously we support ffmpeg here and I have no experience with avconv.

For a complete guide to get ffmpeg in Ubuntu see:
https://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide

Then you can try:
    ffmpeg -i "$ORIG" -s hd480 -vcodec libx264 -acodec copy "$NEW"

This will use the default settings for preset (medium) and crf value
(23). You can easily change them to suit your needs:
    ffmpeg -i "$ORIG" -s hd480 -vcodec libx264 -preset slow -crf 20 \
    -acodec copy "$NEW"

General usage is to use the slowest preset you have patience for and
the highest crf value that still gives you an acceptable quality.
Available presets are: ultrafast, superfast, veryfast, faster, fast,
medium, slow, slower, veryslow. I omitted the "placebo" preset because
it is a joke and a complete waste of time. A sane crf value range is
18-28 (a lower value is higher quality), but of course it depends on
your source and whatever needs and restrictions you have on your output.

The "-threads 0" option is now redundant as it is now automatically
applied.

(It would have made sense for this report if you included information

Then I suspect you have to pass --extra-cflags=-I/usr/local/include

Subject: [FFmpeg-user] Extracting one image every n-th frame
Message-ID: <000601cd3087$04911e70$0db35b50$@afkbio.de>

I am trying to extract single frames from movies every n-th frame.

What I am currently using is:
>ffmpeg -i movie.avi -vf select="not(mod(n\,<n>))","scale=640:-1"  -an export%d.jpeg

The issue however is, that this call does export N images from the SAME frame, so if I set n=100 I would end up with 100 similar images from the first frame, then 100 similar images from the 100th frame and so on. Obviously this is not what I want to achieve.

What I would like to end up with is:
1 Image of Frame N
1 Image of Frame N*1
1 Image of Frame N*2
And so on

I have tried the following as workaround, where X=<source fps> / <n>:
>ffmpeg -i movie.avi -r <X> -vf select="not(mod(n\,<n>))","scale=640:-1"  -an export%d.jpeg

This seems to work, however I don?t think that this is a very elegant approach + there might be small shifts due to round errors.. Is there any way of improving this?

Your problem is that the select filter produces a variable framerate output,
which just happens to be constant in your case but ffmpeg can not know it.
The image2 muxer does not support variable framerate. You need to use the
-vsync option.

> 1 Image of Frame N
> 1 Image of Frame N*1

That is the same.

This is perfectly correct, but then the select filter becomes redundant and
useless. And of course, it can not replace different select formulas.

Hi everybody,

I need some help to understand what ffmpeg is printing on my terminal, when
i use the "-debug mb_type" option.

It displays:

What is the interpretation of the value 0 or 2 for "NAL"? what "POC", "I",
"P" and "SKIP" refer to ?

Unrelated to your problem:
Please understand that 10.3 is not the latest version, the latest 
version is always current git head.

You will have to post the tail of config.log (beginning with 
check_lib) and information where you installed x264 if you need help.

Isn't this a debug message from x264, and not from FFmpeg?

Subject: [FFmpeg-user] metadata editing wrong
Message-ID: <B23495A0-0851-4E51-BACD-D3DB842F57BB@gmail.com>

When I ask ffmpeg to change one metadata element in an audio stream, it seems to plan
 to do the right thing, but it ends up altering all the metadata and not doing the one change I want. 
Apparently I don't understand how metadata editing is supposed to work.

Following are the command line, complete output 
(notice the output metadata looks like what I asked for), 
and finally ffmpeg's look at the new file, with the altered metadata.

Thanks for any help,
Jim

I investigated this a little further, in the hope that I would hear
something in the meantime - so please forgive my "double posting".

I am running two instances of ffmpeg simultaneously, using

ffmpeg -loglevel panic -f video4linux2 -framerate 30 -video_size hd720
-input_format mjpeg -fflags igndts -an -i /dev/video0 -c:v copy -an
/HDD2/test1.mjpeg

and

ffmpeg -loglevel panic -f video4linux2 -framerate 30 -video_size hd720
-input_format mjpeg -fflags igndts -an -i /dev/video0 -c:v copy -an
/HDD3/test2.mjpeg

I am still getting the same errors along the line I have posted above,
"[mjpeg @ 0x639a00] Application provided invalid, non monotonically
increasing dts to muxer in stream 0: 100961 >= 73082", which, of course,
the loglevel suppresses now.

I am also encountering occasional framedrops that ffmpeg does not report
(even without any -loglevel restriction). I have manually set the
bandwidth in the uvc_video.c v4l driver to 3072 (as per:
http://www.mail-archive.com/linux-uvc-devel at lists.berlios.de/msg04783.html),
using two different USB buses (one PCIE USB3 card, and the onboard
USB2). I'm also running it without x server (init level 3), and the CPU
usage is about 18% of each core (dual core Athlon 4000+), and I am
saving each file to a separate hard drive. In other words, there should
be enough bandwidth and computing power available. Could that be an
effect of the dts muxer errors reported by ffmpeg?

Shouldn't the -an option theoretically avoid that altogether, or do I
misunderstand what that error means?

Also, could you provide me with further indications how the v4l video
options could be implemented?

One more thing that confuses me: I am allegedly recording at 30fps, yet
ffmpeg reports 25fps when using ffmpeg -i /HDD2/test1.mjpeg, and ffplay
also plays them at 25fps unless I use the -framerate 30 setting.

Thanks for your help!
Goetz

PhotoRec allowed me to recover the file from the camera SD card, thanks. It didn't find it on my HDD nevertheless, fyi.

Hi all,

I cross compiled ffmpeg after that I found following statement while
transcoding-
[libx264@ 035624A0]: using cpu capabilities: none!

While the pre-built binary from *"http://ffmpeg.zeranoe.com/builds/" *It
gave following statement while transcoding-
[libx264@ 035624A0]:  using cpu capabilities: MMX2 SSE2Fast SSSE3
FastShuffle SSE 4.2

Note: I executed same command in both version on same input file., I am
using Windows 7 64-bit

What I want to know is, Do I need to reconfigure my ffmpeg build to use CPU
capabilities.?
I am using *--enable-runtime-cpudetect *while configuring.

Thanks a lot for your answers, there's very interesting tips :) In the end I
decided to rename the images in a temporal folder as Kevin suggested, and it
worked just fine.

Is there any performance difference when I use ffmpeg 32-bit vs 64-bit on
64-bit windows 7 OS?
I downloaded 64-bit version from zeranoe and found that it was slow from
32-bit one? Any comments

That is only a good idea if you plan to distribute your FFmpeg 
binary, or in other words: Do not use this option if you 
compile FFmpeg for yourself.

I don't think so. In fact, 64-bit version should be faster than the 32-bit
one, because it should take advantages of your 64-bit architecture.

I don't know either, but surely if it interests you, it would be
trivial to compare the two variants by trying it out.

You don't do anything while building ffmpeg to get that message.  You
need to rebuild (lib)x264 and stop using --disable-asm.  If you get an
error message when you attempt that, perhaps you should follow what it says.

Do I need to enable 'dcodec' when compiling? If so, what do I add to my
existing configuration. I've not been able to find the answer from searching

Your ffmpeg is too old to support -dcodec. FFmpeg does not use SVN
anymore and the last commit (r26402) was on 2011-01-19 while -dcodec
was probably supported around 2011-05-03. See the FFmpeg Download page
on details on how to get the recent source with Git.

That worked. Thank you very much. 

However, the -dcodec copy did not make an exact copy of the ProRes timecode
track. When opened in Quicktime, the new file shows the "Standard" counter
and the "Frame Count" but not include the "SMPTE Non-Drop" option as it does
in the original. I will have to do more hunting around to see what I am
leaving out.

Actually, I may have been using the wrong command, the Quicktime file won't
open at all when using -map 0:25.0:25 -dcodec copy  (there are 24 tracks of
audio in this file). If I leave out that 25th data/timecode track in the
command then the file is created as expected. adding that one last command
creates a file that is not able to be opened.

This looks like the same bug as reported here: https://ffmpeg.org/trac/ffmpeg/ticket/236. At this time ffmpeg can not produce a QuickTime output with a QuickTime timecode track, either with -c:d copy or -timecode.

Hello All

I have to plug in my own IDCT for Mpeg4 codec. I have been trying to

vlc decoding is being performed. Could someone tell me the exact

Subject: [FFmpeg-user] Loss of anamorphic aspect ration in conversion from
	MKV/H264 to MpegTS/H264
Message-ID: <CAC-4XGuS1Lne0n69O7J_L_Mdz8_73pzNb2Y5p2voXoeOwFQVdQ@mail.gmail.com>

Hi,

I have got a bunch of MKV/H264 files that I would like to
format-convert to MpegTS, but I'm failing to maintain the anamorphic
aspect ratio.

I've tried the conversion as;

 $ avconv -i ~/Video/test.mkv -vcodec copy -acodec copy -bsf
h264_mp4toannexb ~/test.ts

I also tried using ffmpeg to produce raw h264 bitstream as;

 $ avconv -i ~/Video/test.mkv -vcodec copy -bsf h264_mp4toannexb ~/test.h264

The conversion itself works fine, but the anamorphic aspect-ratio is
lost, so the resulting TS is played with 1x1 pixel ratio. I've tried
forcing it with --aspect, I've tried different tools (vlc, mencoder,
gstreamer...), but nomatter what I don't seem to get the aspect ratio
right (or even manage to affect it, at all).

Now I wonder, are there some limitations to h264 in MpegTS that
prevents anamorphic resolutions? I've tried reading the H264 specs,
including Annex B, and while I did find some references, it's a lot to
take in at once, so I reached no definite conclusion.

Or am I doing something wrong?

Best Regards
/ Ulrik

I don't think you can save aspect ratio in a h264 bitstream.

Actually, I just got that answer myself, through trying to fully
transcode to TS/H264 with VLC, I get a working anamorphic video:

Is it plausible that the original MKV does not contain AR-info in the
h264-stream itself, but only in MKV-headers, such that it works as
long as the container retains the format, but not when splitting into
a TS or raw H264?

This is an intentionally broken version of FFmpeg with several 
hundred known regressions, some of them security relevant, we 
therefore cannot support it.
Please see http://ffmpeg.org/download.html for supported versions.

If you can reproduce the problem with FFmpeg, please post 
relevant output, there may be a bug.

At the container level, mpegts does not support specifying a video 
aspect ratio. It's assumed that the video elementary stream takes care 
of that.

In h.264 elementary stream, aspect ratio is optional. If you have the 
standard, see appendix E.1.1, "aspect_ratio_idc".

It seems your original streams don't contain this field. If you want 
this to work in mpegts, you'll need a tool that inserts this information 
in the elementary stream itself.

I'm not aware of such a tool. You could re-encode, of course.

What are you trying to do exactly? Your config.log uses options
completely different than the guide you linked to.

Also, there is a version of that guide more suitable for Red Hat:

Here is the command I find after googling and reading here
http://ffmpeg.org/libavfilter.html  (overlay section)

ffmpeg -i video1.avi -vf "movie=md.png [logo]; [in][logo] overlay=W-w-10:10
[out]" output3.avi

video1.avi - source video
md.png - name of the logo (it could be a bmp/jpg)
output3.avi - the processed avi file

Hope it helps you.

the links (labels into []) are described in the documentation which isn't
very clear enough in my opinion.
Any reading suggested?

Regards

Rossana

Hi
I did use Avisynth for such, this has to be pipelined with ffmpeg (the 
avisynth
output to the ffmpeg input )
http://avisynth.org/mediawiki/Main_Page
You also could insert a logo which is moving all around the screen this 
means which
it cannot be replaced automatically by an other one
  regards

Hi

he is my batch file the input is the file to encode
the <file>.avs is created with avisynth and
is the input ffmpeg file
you'll find attached the animated logo which is not from myself
an avisynth gourou did it for me
sorry it is commeted in french but if you need a translation I will
help

you'll have also attached the file created by the batch file in this 
particular
case I was using vob input file. All dll files are from avisynth download
the only one filter which can be missing is the attached one




  set source_file= <infile>.avi
  set f_avs        = temp.avs

  echo global dir_source      = "%source_file%" > %f_avs%
  echo global dir_plug          = "c:/streaming/avisynth/" >> %f_avs%
  echo global infile               = "%source_file%" >> %f_avs%
  echo     LoadPlugin (dir_plug + "MSharpen.dll") >> %f_avs%
  echo video = DirectShowSource(infile).converttoyuy2() >> %f_avs%

  echo global logofile        = "c:/streaming/programme/images/" + 
"utl.jpg" >> %f_avs%
  echo     Import( dir_plug + "InsertAnimateLogo.avs") >> %f_avs%
  echo logo = reduceby2(ReduceBy2(ImageSource(logofile))) >> %f_avs%

   echo opacity=0.4 >> %f_avs%"
   echo c_alpha=$ffffff >> %f_avs%"
   echo 
insertAnimateLogo(video,logo,mode=1,tolerance=50,opacity=opacity,pad=20,speed=1,showmask=false,c_alpha=c_alpha) 
 >> %f_avs%"

then

  ffmpeg -i %f_avs%   ..................................

Hi ffmpeg experts!

I want to decode the H.264 bitstream using HW accerlerator, but I can't 
use it.

My configure and version on WinGW are as follows:

ffmpeg version 0.9.1.git Copyright (c) 2000-2012 the FFmpeg developers

When I reviewd the config.h after compiling, the results was as 
following

   #define CONFIG_HWACCELS 0
   #define CONFIG_H264_DXVA2_HWACCEL 0

How do I solves the problem?

Thank you in advances

Subject: [FFmpeg-user] Shorten the delay
Message-ID: <CAKS_=j_OAMdx25fGjgedryrswcLMphp_pcbWw+jazpAhsegmFw@mail.gmail.com>

Hello all,

I'm using ffmpeg&ffserver to stream the X11 desktop display to another PC
(over LAN) in real-time.
Here are my commands:

ffserver -f /etc/ffserver_kkuei.conf &
ffmpeg -f alsa -i hw:0,1 -f x11grab -s 1280x720 -i :0.0 -acodec libfaac
-vcodec libx264  http://localhost:10090/feed_kkuei.ffm
(ffserver is configured as a RTSP&RTP server)

In another PC, I just use ffplay to play the RTSP stream.

In my observation, there is about 2.5 seconds delay between the input (X11
display) and output (ffplay) .
The PC is under the same LAN and I'm sure the RTP/UDP didn't waste much ot
the time.

The delay is really a concern in our use case.

It will be very appreciated if anyone can tell me how to shorten the delay.

Cheers,

Kevin Kuei

Always use current git head if you are not distributing FFmpeg

These options look all unneeded, they are the default iirc.

This is not advisable if you care about performance.

Look at config.log, search for dxva, it will tell you that 
you have to install additional headers.

Can you avoid the delay if you use a fast internal encoder 
(mpeg2video) and no audio?

Thank you, very informative.

I guess this is exactly it then, that the original MKV-file has the
aspect-ratio in the MKV, but missing in the H264-stream, and when
changing to mpegts, there's no place to put the aspect-ratio in the
mkv. I guess it will be transcoding for me then, time to buy some more
CPU.

one question to this

i usually compile with runtime-cpudetec combined with
explicit CFLAGS reflecting the best possible options
for all CPUs in my working and private environment

my idea for this is that GCC can especially by
"-mtune=core2 -msse4.1" optimize any binary code
while with "runtime-cpudetect" on my personal
workstation AVX can be used which is not available
currently on all machines

is my assumption completly wrong here?

--enable-runtime-cpudetect --extra-cflags='-O6 -march=core2 -mtune=core2 -mmmx -msse2 -msse3 -msse4.1 -fopenmp
-mfpmath=sse -fno-delete-null-pointer-checks -fstack-protector --param=ssp-buffer-size=4 -pipe -D_FORTIFY_SOURCE=2
-fexceptions'

Subject: [FFmpeg-user] [ffmpeg-user] Usage of AVDiscard
	AVContext::skip_frame etc.
Message-ID: <4FB53797.4060905@googlemail.com>

Hi,

I am developing a VoIP software using opalvoip 
[http://www.opalvoip.org]. It is using ffmpeg to decode an incoming 
H.264 stream. There, I have some issues when I have a high network load. 
This is causing the packets coming later than usual to the decoder. 
Unfortunately, if packets get lost during transmission, e.g. when the 
connection is stalled for short, it seems to me that ffmpeg buffers the 
last packets until the next correct packets arrive (but I am absolutely 
not sure, if it is so...). This leads to a high delay of the video 
stream and asynchronous playback of audio and video.

I was wondering if I can tell ffmpeg to decode the incoming frames as 
fast as possible. So, I found the AVDiscard AVContext::skip_frame, but I 
have no clue how to use them. Are these parameters the correct way to 
achieve the required behaviour?

Thank you for every kind of help!

Denis

Not directly with libavfilter + overlay.

What you could do, is to create a movie out of the logo, and make it
disapper/appear when it is convenient, not very practical but should
work.

Also note that there is nothing preventing to implement the feature in
the overlay filter and I fancied to do that some times, please add a
ticket so it won't be discarded.

The format used is irrelevant for filtering purposes.

Thanks, not very practical indeed, even though it could works when I figure
it out (how to supress a logo for certain frames).
I have to say I am doing it by console.

Hi Carl,

Sorry that I'm not quite understand what you mean.
Can you provide the link of the "fast internal encoder"?
Is it installed in ffmpeg??
One more thing is, we still need audio..

I mean is the problem you see only reproducible with 
-acodec libfaac -vcodec libx264 (which is very 
resource-hungry) or also with -an -vcodec mpeg2video?

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

Does anyone have any ideas how to change the gamma of a sequence? I've 
seen in the documentation that it is possible thought it looks like it 
can only be done by ffplay when playing back a video. I need this gamma 
change burnt into the actual frames.

Any ideas?

If your CFLAGS allow for a faster ffmpeg executable than 
default compilation (with ./configure && make) that would 
be a bug in FFmpeg (that should be reported).

No, but if you are interested in performance, it is better 
to compile for each target individually.
(At least, this has been the information for a long time.)

Hi Carl!

Thank you for your response quickly.

I did it according to your advices and the config.h file created as 
following:

   #define CONFIG_HWACCELS 1
   #define CONFIG_H264_DXVA2_HWACCEL 1

I want to recognize dxva2_h264 in my source but I can't use it.
Please you think I am big ffmpeg beginner.
My source is next following and what do I do?

AVHWAccel h264_dxva2_hwaccel = NULL;

av_register_all();
avcodec_register_all();

pGBCodec = avcodec_find_decoder(CODEC_ID_H264);

if(pGBCodec)
{
	pGBContext	=	avcodec_alloc_context();
	avcodec_get_context_defaults(pGBContext);

	if(!h264_dxva2_hwaccel)
	{
		AVHWAccel* hwaccel = NULL;
		while(hwaccel = av_hwaccel_next(hwaccel))
		{
			if(hwaccel->pix_fmt == PIX_FMT_DXVA2_VLD && hwaccel->id == 
CODEC_ID_H264)
			{
				h264_dxva2_hwaccel = hwaccel;
				printf("dxva2_hwaccel = %s",h264_dxva2_hwaccel->name);
				break;
			}
		}
	}
	if(!h264_dxva2_hwaccel)
	{
		printf("dxv2 not supported by ffmpeg");
		exit(0);
	}
          if(avcodec_open(pGBContext, pGBCodec) < 0)
	{
		avcodec_close(pGBContext);
		av_free(pGBContext);

		pGBContext = NULL;
	}
}

Best regards,
nrson

Carl,

Thank you for your help.

My knowledge of morphing is very limited. I would appreciate your help in clearing a confusion that I have.I intend to process images that were digitized from a movie film. There are about 24 images in a second. As there is just a little change from one image to another, I am thinking these images must be as good as morphed images. Do you think morphing would still be required?

Regards,
Peter

FFmpeg has no morphing filter (yet), patch welcome.

You originally wrote that you need morphing.
If you want 24fps output, I don't know what morphing could be good 
for, if you need (real) higher fps output, you will need morphing.

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

This is old, please test current git head, if you still see 
errors, please provide your command line together with complete, 
uncut console output (not your command followed by an error 
followed by an edited part of the console output).

That depends most likely on the default output quality. You can
increase the output bitrate or the quality to fix that, use a
different lossy codec with a better quality/compression ratio (AVI
assumes MPEG-4 part 2 by default, but you can change that through the
-vcodec option), or use a lossless codec.

Check the lut filter:
http://ffmpeg.org/libavfilter.html#lut_002c-lutrgb_002c-lutyuv

I guess this is supported also through some mp wrapped filters, or
through frei0r.

X11 session recording with ffmpeg:
ffmpeg -f oss -i /dev/audio -f x11grab -s $WIDTHx$HEIGHT -r 5 -i :0.0 \
    x11-session.avi
Use xdpyinfo to get WIDTH and HEIGHT values.

Try to add the -b (1000K works fine for web) parameter to your command:

ffmpeg -i input.avi  *-b 1000K* -vf "movie=watermark.png [logo]; [in][logo]
overlay=W-w-10:H-h-10[out]" output.avi

Sorry, since I am pretty newbie in this subject. You mention to increase
the bitrate, use a diffferent lossy codec.
Do you have a more explicit example? I appreciate very much, nonethless
I'll take a read on what you mentioned.

Thanks and regards

WTF - how comes that each week another once sends "unsubcribe"
to some mailing-list - if you are able to register you should
be able to rad, understand and deal with the way a list works

especially do not reply to a RANDOM message with "unsubscribe"

EACH single mail of any mailing-list contains headers

Hi, well I did what you suggested, but it didn't improve the result so much.

First I found out the codec: ffmpeg -i video1.avi

Seems stream 0 codec frame rate differs from container frame rate: 30000.00
(30000/1) -> 23.98 (24000/1001)
Input #0, avi, from 'video1.avi':
  Metadata:
    encoder         : VirtualDubMod 1.5.10.1 (build 2366/release)
  Duration: 00:23:18.52, start: 0.000000, bitrate: 1308 kb/s
    Stream #0.0: Video: mpeg4, yuv420p, 720x400 [PAR 1:1 DAR 9:5], 23.98
fps, 23.98 tbr, 23.98 tbn, 30k tbc
    Stream #0.1: Audio: mp3, 44100 Hz, stereo, s16, 128 kb/s

And then I applied the codec and bitrate:

ffmpeg -i video1.avi -vf "movie=md.png [logo]; [in][logo]
overlay=W-w-10:10[out]" -vcodec mpeg4 -b 1400 out1.avi

Any suggestion? Thanks a lot

Rossana

Subject: [FFmpeg-user] Error while encoding UDP H.264 stream
Message-ID: <1337494054241-4646646.post@n4.nabble.com>

Hello,

I am trying to encode UDP MPEG-TS H.264 stream and getting "non-existing SPS
0 referenced in buffering period" error continuously. After 1 or 2 hours of
encoding, FFMPEG stops suddenly. 

The error is occuring even if I write to a file. I tried with fifo_size and
buffer_size options. But, no change in the error. I read through few posts
on this mailing list and tried those suggestions. But, still not able to fix
this. Please help in fixing this error.

Below is the FFMPEG command I am using: 

ffmpeg -y -i udp://@224.2.4.5:9900 -acodec libfaac -ac 2 -ab 64k -vcodec
libx264 -f mpegts -threads 0 -async 2 -b:v 1200k udp://224.2.9.4:9900 2>
logout.txt 

Below is the truncated console output.

Value for -b is expressed in *bits per seconds*, so 1400 is
definitively low, use -b 1400k instead.

Also you may try the libx264 encoder (mpeg4 is the default choice for
the AVI container, so no need to explicitely specify it).

Subject: [FFmpeg-user] Avoiding rollover pts due to input looping
Message-ID: <CALdTkGExGQGpaQ9=nzo-UkhvEMrErFKgqd=Wo7Gj2H4jcbCb+g@mail.gmail.com>

I would like to avoid to handle pts rollover due to input looping. In
particular the need to reinitialize filter graphs.

Can I do that by modifying the AVPacket::pts after av_read_frame in
order to get continuous pts, or can that mess up decoders?

Finally worked in an aceptable way, with a very good resolution.


ffmpeg -i video1.avi -vf "movie=md.png [logo]; [in][logo]
overlay=W-w-10:10[out]"  -b 1400k outprueba.avi

Even the result is ok, I got this message.
Press ctrl-c to stop encoding
[mp3 @ 0x7e8c00] incomplete frame293576kB time=1398.36
bitrate=1719.9kbits/s

Is there a crucial issue I will be aware of?


I'va also tryed with -vcode libx265, but after encoding it misses some
frames.  The final video last less minutes than the original.
I guess it could be something with a wrong frame econding or  something
like that..

Thanks a lot for your help.

Hi ffmpeg experts!
I was writer previous sending e-mail(title:how do I use the HW 
acclerator?).
But anybody was not reply e-mail.
I am very confused sataus.

Anyway,
I thought if config.h file was done as following, My graphic 
board(Intel i5, Nvida Gefoarce) was recognized.
    #define CONFIG_HWACCELS 1
    #define CONFIG_H264_DXVA2_HWACCEL 1
But My graphic board did't it.

I have found ff_h264_decoder in h264.c changed to #if 
CONFIG_H264_DXVA2_HWACCEL ~ #endif
during searching in internet.

Before: AVCodec ff_h264_decoder = {
	.name                  = "h264",
	.type                  = AVMEDIA_TYPE_VIDEO,
	.id                    = CODEC_ID_H264,
	.priv_data_size        = sizeof(H264Context),
	.init                  = ff_h264_decode_init,
	.close                 = ff_h264_decode_end,
	.decode                = decode_frame,
	.capabilities          = CODEC_CAP_DR1 |CODEC_CAP_DELAY | 
CODEC_CAP_SLICE_THREADS |CODEC_CAP_FRAME_THREADS,
	.flush                 = flush_dpb,
	.long_name             = NULL_IF_CONFIG_SMALL("H.264 / AVC / MPEG-4 
AVC / MPEG-4 part 10"),
	.init_thread_copy      = 
ONLY_IF_THREADS_ENABLED(decode_init_thread_copy),
	.update_thread_context = 
ONLY_IF_THREADS_ENABLED(decode_update_thread_context),
	.profiles              = NULL_IF_CONFIG_SMALL(profiles),
	.priv_class            = &h264_class,
};
After:
#if CONFIG_H264_DXVA2_HWACCEL
#include "dxva2_h264.c"
AVCodec ff_h264_dxva_decoder = {
     .name                  = "h264_dxva2",
     .type                  = AVMEDIA_TYPE_VIDEO,
     .id                    = CODEC_ID_H264,
     .priv_data_size        = sizeof(H264Context),
     .init                  = ff_h264_decode_init,
     .close                 = ff_h264_decode_end,
	.decode					=	decode_slice,
     .capabilities          = CODEC_CAP_DR1 | CODEC_CAP_DELAY | 
CODEC_CAP_SLICE_THREADS |
                              CODEC_CAP_FRAME_THREADS, 
CODEC_CAP_HWACCEL,
     .flush                 = flush_dpb,
     .long_name             = NULL_IF_CONFIG_SMALL("H.264 / AVC / MPEG-4 
AVC / MPEG-4 part 10"),
     .init_thread_copy      = 
ONLY_IF_THREADS_ENABLED(decode_init_thread_copy),
     .update_thread_context = 
ONLY_IF_THREADS_ENABLED(decode_update_thread_context),
     .profiles              = NULL_IF_CONFIG_SMALL(profiles),
     .priv_class            = &h264_class,
	.pix_fmts			= (const enum PixelFormat[]){PIX_FMT_YUV420P, 
PIX_FMT_NONE},
};
#endif

There is errors after compiling as following
  libavcodec/dxva2_h264.c:396:12: error: conflicting types for 
'decode_slice'
  libavcodec/h264.c:3972:12: note: previous definition of 'decode_slice' 
was here
  libavcodec/h264.c:1299:12: warning: 'decode_init_thread_copy' defined 
but not used [-Wunused-function]
  libavcodec/h264.c:1315:12: warning: 'decode_update_thread_context' 
defined but not used [-Wunused-function]
  libavcodec/h264.c:4491:12: warning: 'decode_frame' defined but not 
used [-Wunused-function]

I thought that my works have been wrongly.
How can I use dxva2_h264?
I am really big ffmpeg user, please help me...!!!

Best regards in advances

you can try adding the original film frame rate before the input and the
desired output frame rate before the output, that should fix it.


*ffmpeg -i  -r 24 video1.avi -vf "movie=md.png [logo]; [in][logo]
overlay=W-w-10:10[out]" **-r 24 ** -b 1400k   outprueba.avi*

good luck!

Decoders should handle this, so what you propose should be ok.

If all the frames arrive with timestamps, you should be good.

But if some arriving frames do not have timestamps, and libavformat is 
"helpfully" filling them in, make sure to double check that libavformat 
is generating accurate values before and after the rollover.

Don't forget that PTS might not be monotonic.

Sorry, i made a writing mistake, the -r must be  before the -i input.avi,
not in between.

Message-ID: <CAHRV6b5Sk95DNAi6f9m-icqHo5ZXgBpbw3Qc4k8RPVseV1J4rw@mail.gmail.com>

I apologize for the potential silly question....

I've been having a lot of success with ProRes QTs from ffmbc but less
so on the ffmpeg front. Now for the silly question: has the ffmbc fork
now strayed so far from ffmpeg that the ProRes code from ffmbc can't
be brought back into the fold?

With ffmbc, I can make ProRes 4444 without a hitch. Also, there seems
to be a problem with FCP not accepting ffmpeg ProRes files as "proper"
but we don't seem to have this issue with ffmbc. I'm not a developer
so I'm not sure how challenging it would be, but I would sure love to
bring ffmbc's ProRes support into ffmpeg.

Subject: [FFmpeg-user] Video files splitting and merging issue
Message-ID: <CAJQ5m2PwiaxsFLqoF=tRoKc3U5StFj3WQP9y+MZ09oVnhSWTsg@mail.gmail.com>

Hi all,
As we know, unless files are in privileged raw format such as mpg, we cant
merge those files by simple binary concatenation.
I found this tool mp4box, which is able to concatenate mp4 files. Well
thats great, but the problem is it can do that for mp4 only.

One more thing ,Please correct me if i am wrong, If I am trying to cut a
segment of a 3 hrs video from 20th minute to 30th minute, ffmpeg will have
to parse the video till 20th segment and then start processing. If thats
true, then that is bad.

What I would Like to ask from community is Can somebody please let me know
following things.

1) What all formats can be stitched together by simple binary concatenation?
2) Is there any generic command line tool available which can split and
merge any formats?

Hi nrson,

I've similarly been battling to get DXVA2 to work for H264 decoding. The following is what I've learned:

libavcodec does include some support for DXVA2, but it doesn't do all the work necessary to be able to automatically use DXVA2.
The "Player" (i.e. the program that you write to use libavcodec) needs to do half of the work. ffmpeg.exe and ffplay.exe have not been written to use DXVA2.
Everyone points to the VLC open source player as the best (only) example of how to use DXVA2 with libavcodec. Unfortunately VLC is very complex
and hard to even recompile on Windows. It would be great to have a simple/minimal player example that could demonstrate how to do it.

>From what I understand the basic steps are to:
1) get ffmpeg libraries to compile with DXVA2 support enabled.
2) Create a DirectXVideoDecoderService (http://msdn.microsoft.com/en-us/library/windows/desktop/aa965245(v=vs.85).aspx#Decoding)
3) Choose a Decoder configuration and create an array of Direct3DSurfaces
3) Create a dxva_context structure and initialize it's fields with the above objects
4) Get the AVCodecContext for your video stream, e.g: pCodecCtx = pFormatCtx->streams[videoStream]->codec
5) Before you open the decoder, override the get_format, get_buffer, release_buffer functions of this context, eg: pCodecCtx->get_format = MyGetFormat
6) Set the hwaccel_context of this context to the dxva_context structure created earlier.
7) Your get_format function needs to select the PIX_FMT_DXVA2_VLD pixel format.
8) Your get_buffer function needs to return one of your unused Direct3DSurfaces
9) Your release_buffer function needs to note that your Direct3DSurface is now available to be reused.

I've followed these steps and got it to run. It definitely does use the DXVA accelerator and it doesn't crash, but the output frames are garbled rubbish, which by the was is the same output that I get when I turn on DXVA2 decoding in VLC. I suspect the problem is that I haven't set all of the corrrect parameter values when configuring my DirectX objects to match the video format that I'm trying to play. I know that DVXA2 does definitely work on my machine because I can see Windows Media Player using it successfully.

BTW, a useful tool for diagnosing DXVA2 is DXVAChecker (http://bluesky23.yu-nagi.com/en/#DXVAChecker)

Please let me know if you have any success.

Cheers, Wayne.

Hi ffmpeg experts!
I was writer previous sending e-mail(title:how do I use the HW
acclerator?).
But anybody was not reply e-mail.
I am very confused sataus.

Anyway,
I thought if config.h file was done as following, My graphic
board(Intel i5, Nvida Gefoarce) was recognized.
    #define CONFIG_HWACCELS 1
    #define CONFIG_H264_DXVA2_HWACCEL 1
But My graphic board did't it.

I have found ff_h264_decoder in h264.c changed to #if
CONFIG_H264_DXVA2_HWACCEL ~ #endif
during searching in internet.

Before: AVCodec ff_h264_decoder = {
        .name                  = "h264",
        .type                  = AVMEDIA_TYPE_VIDEO,
        .id                    = CODEC_ID_H264,
        .priv_data_size        = sizeof(H264Context),
        .init                  = ff_h264_decode_init,
        .close                 = ff_h264_decode_end,
        .decode                = decode_frame,
        .capabilities          = CODEC_CAP_DR1 |CODEC_CAP_DELAY |
CODEC_CAP_SLICE_THREADS |CODEC_CAP_FRAME_THREADS,
        .flush                 = flush_dpb,
        .long_name             = NULL_IF_CONFIG_SMALL("H.264 / AVC / MPEG-4
AVC / MPEG-4 part 10"),
        .init_thread_copy      =
ONLY_IF_THREADS_ENABLED(decode_init_thread_copy),
        .update_thread_context =
ONLY_IF_THREADS_ENABLED(decode_update_thread_context),
        .profiles              = NULL_IF_CONFIG_SMALL(profiles),
        .priv_class            = &h264_class,
};
After:
#if CONFIG_H264_DXVA2_HWACCEL
#include "dxva2_h264.c"
AVCodec ff_h264_dxva_decoder = {

I thought that my works have been wrongly.
How can I use dxva2_h264?
I am really big ffmpeg user, please help me...!!!

Subject: [FFmpeg-user] Adjusting libavdevice/v4l2.c to support V4L2 controls
Message-ID: <4FBADFAE.3050406@gmail.com>

Hi everybody,

in order to keep things a little easier to follow I have decided to
start a new thread and apologize for this doubling up. I also apologize
that I keep bringing this up, but I think it would be a very beneficial
feature for ffmpeg; VLC allows these controls but ffmpeg is far more useful.

I am still trying to find a way to control the V4L2 control IDs (eg.
http://v4l2spec.bytesex.org/spec/x542.htm,
http://v4l2spec.bytesex.org/spec/x802.htm particularly Section 1.9.6,
and http://linuxtv.org/downloads/v4l-dvb-apis/control.html, and
http://linuxtv.org/downloads/v4l-dvb-apis/extended-controls.html). I am
facing the problem that I am using two webcams with an autofocus and an
auto-white-balance, which regularly screws up the image, and makes
post-processing very difficult as both streams need to be almost identical.

In my previous email (subject: Re: [FFmpeg-user] Question about v4l2
controls and ffmpeg, also dts muxer problems) I got the following reply:

>>I am curious though if there is any way of controlling the v4l2
control ids through ffmpeg,
>> i.e. things like V4L2_CID_WHITE_BALANCE_TEMPERATURE, V4L2_CID_DO_WHITE_
>> BALANCE, V4L2_CID_FOCUS_AUTO ...
> No, but I believe it should be straight-forward to implement, see
v4l2_set_parameters() and
> options[] in libavdevice/v4l2.c

I am primarily interested in the autofocus and white balance features -
i.e. if I could just give ffmpeg the right integer value for my recording.

I am using the following command (for each camera):

ffmpeg -f video4linux2 -framerate 30 -video_size hd720 -input_format mjpeg -fflags igndts -an -i /dev/video0 -c:v copy -an /HDD2/test1.mjpeg

Ideally, I think, this could be something like a -v4l2_ctl_id flag or so.

I am not a programmer and thus at a loss as to how to get that into
libavdevice/v4l2.c as suggested. Could you help me out with that or
provide me with further pointers?

Thank you very much - I think you guys are doing a great job!
Goetz

I am sorry, but I currently have no access to my hardware that has a 
v4l2 device, meaning I cannot work on this atm.
You could try to add ioctl's to device_init() in libavdevice/v4l2.c, 
it should be easy to add options once that works. If you are unable 
to test this, you will have to wait until somebody works on it...

(Please consider opening a ticket on trac, you may point to these 
mailing list threads, but do add all information into trac.)

Sorry, Carl Eugen

I can confirm that above is correct, I don't know why it does not 
work for you, I would expect that your hardware / driver 
combination is the reason.

I suspect your issue should be fixed, for future questions, please 
always post the complete, uncut console output, it makes 
understanding the problems much easier.

Also consider looking at http://ffmpeg.org/download.html for 
supported versions of FFmpeg, your version may be intentionally 
broken.

Well as I said before finally works.

ffmpeg -i video1.avi -vf "movie=md.png [logo]; [in][logo]
overlay=W-w-10:10[out]"  -b 1400k outprueba.avi

The only fact I can argue is when I use -vcode libx264 it misses
frames and the duration of the clip is less than the original.

I guess is something wrong with the avi file and some inconsistency.

Thanks

Rossana

Do you feel that this is sufficient for the developers to 
understand, reproduce and fix the problem?

Carl, here's all the necessary information needed to fix this very old
and annoying bug.

This has been discussed before and the issue, as explained by Baptiste
Coudurier (who has already fixed this in ffmbc), is a problem with
ffmpeg's mov muxer writing audio chunk sizes incorrectly (or at least
not in a way Final Cut Pro wants):

http://ffmpeg.org/pipermail/ffmpeg-user/2012-March/005682.html

As Baptiste explains, "FCP expects audio chunks to be approximately
48000 samples."

Movies with co64 atoms (that is, MOVs over 4GB) do not have this
problem and do not throw the media performance warning in Final Cut
Pro. So, what this means is that audio chunk sizes are written
correctly when co64 is used (i.e. written with 64 bit offsets), just
not when 32 bit chunk offsets (stco) are written.

This is a BIG HINT for anyone who wants to fix this. I would gladly do
it, but I don't know avcodec source well enough. This fix would be
better handled by someone already familiar with avcodec source,
especially movenc.c.

I will happily assist anyone who needs to verify their work with Final
Cut Pro if they don't have a Mac.

FFmpeg is a complex library, so there is not a short simple answer to 
your question.

Download the source code and look at the files in the doc/examples/ 
subdirectory. Those examples are not perfect, but should give you an 
idea how the different parts of ffmpeg library work together.

It's a little old, but this tutorial might help your understanding too:

Do you expect the average user to have the technical expertise to give the  
developers all the information they need?

Technical investigation of faults is part of what software engineering is.

after all the pure trolling of you in the past it

Hi everyone

I'm trying to save a rtsp - MJPEG  stream to disk, but a kind of error 
in decoder is found:

   E mpjpeg          MIME multipart JPEG format


As far as I know, the payload type is 26, which corresponds with mjpeg 
video. VLC can

any clue? Am I missing any parameter?

Any advice will be appreciated.

Please try current git head.

Please do not highjack threads, it is considered very rude.

Sorry for the misunderstanding.
  It is not my intention to cause any disturb. I'm new here and I just 
would like to ask for some help.

I also tried to decode this stream with a modern version 0.10.3, but the 
problem looked pretty similar, so I guess it is my fault ;)

Investigating a bit more I've founded more problems like this because of 
the streamer "ingenient technologies media server", so maybe the problem 
came since I'm forcing ffmpeg to decode mjpeg instead of "ingenient 
technologies" mjpg format.

As you can see in the format list, my ffmpeg compilation seems to be 
able to decode that format
(please ignore the version)

   libswscale    2.  0. 0 /  2.  0. 0
  D  ingenient       raw Ingenient MJPEG


Any clue with the parameter I should pass to decode the "ingenient" 
video format?

Kind regards.
Daniel Martinez.

PS. Please take in account that I don't want to cause problems and be 
sure that your support is quite appreciated.

Subject: [FFmpeg-user] mmsh streams and immense buffering
Message-ID: <04e401cd3839$9bcbd2d0$d3637870$@co.uk>

Hi,

 

I am a novice with FFMPEG but have over the years fudged a live streaming
service using the Windows Media format and Windows Media Services. In
hindsight, not perhaps the best course but that's where we are.

 

Myself and a few developers have been attempting to use FFMPEG to transcode
some streams for playback on different devices with some success.  The
problem comes with certain streams. For example, this stream, which works
fine in Windows Media Player or VLC:

 

http://209.105.232.35/cssaitek1

 

(I pass it in as mmsh:// within FFMPEG). The result is:

[wmv3 @ 00000000(some random hex)] Extra data: 8 bits left, value: 0

 

which sits there for a good 3-4 minutes before any data seems to come out
the other side. Sniffing the NIC and looking at the media server stats shows
that data is flowing right from the start however, so something is holding
FFMPEG up.

 

Some streams do not do this, e.g.

 

http://209.105.232.35/csdigitaldanuk

 

(also an mmsh://)

 

These are both live feeds using the same software to encode the streams.

 

The first stream gives this warning after its several minute wait (even
though it goes on to process fine):

[asf @ 00000000003deec0] Stream #0: not enough frames to estimate rate;
consider increasing probesize

 

Whereby the second doesn't.

 

I'm guessing there's an issue with stream #1 at the encoding stage. I have
about 120-140 live streams I can probe and it seems about a third are
affected with this. Is there a hack to make FFMPEG just process example
stream 1 (above) like it does example stream 2 (above) in a timely manner?
I've tried setting -probesize to various random values but I am really a
novice at this and it doesn't seem to make a difference.

 

Any help would be appreciated... I think the issue is fairly easy to
replicate.

 

Thanks,

 

Pat

Don't worry.
The idea would be that you start with http://ffmpeg.org/contact.html 
and that you use Google if you don't understand the terms 
"top-posting" and "thread high-jacking".

Please test current git head and post the command line and the 
complete, uncut output for git head.
It is likely that you simply found a bug, but with the command line 
and the output, there is a higher probability that somebody can 
tell you for sure.

Always post your FFmpeg command line together with complete, uncut 
console output on this list (never post extracts from the output.)

Use a small value for -probesize, I don't know much about mms, but 
FFmpeg and your implementation seem to disagree about timestamps...

Carl,

Ok, a very simple example, since it doesn't seem to matter what I specify
output format to be - the hanging is the same:

(etc).


Feel free to run the same commands on the same streams to test. They are
open and usually available 24 hours a day. I can supply half a dozen more
examples of working to non working which don't seem to have any common cause
(frame size, bit rate etc).

Thanks,

Pat

Why do you think I suggested to use a small value for probesize?

Forgot to mention that 10000 works fine here.

OMG how did I not come across that, I tried 0, 4, 16, 32 up to about 4096.
You're a genius. I was so close yet seemingly so far.

Thanks Carl!

Thanks for your reply, Carl Eugen! Would ssh access to my
v4l2-"experiment" box be of any use? I could set that up this week.

I'll also open a ticket on trac, I'll read up on how to do this this
coming weekend.

Thanks,
Goetz

Carl,

I wonder if you can help me with the next problem!

Weirdly now, if I try to do an on-the-fly conversion to a file, the
problematic streams don't seem to save any data. Those earlier image%d.jpg's
seemed to work but any other format (other than .wmv which works) does not.
This is what happens, for example with a simple command to go to .mp4:

C:\ffmpeg\bin>ffmpeg -probesize 2048 -i "mmsh://209.105.232.35/csmello58"
movie.mp4

Trying to remove 1024 samples, but que empty


When I pressed 'q', FFMpeg actually crashed after outputting the line about
'trying to remove 1024 samples' above. There is no further info other than
the usual 'FFMPEG has stopped working' and the outputting of a windows
memory dump to a temp location (which seems to mean nothing).
The 'movie.mp4' contains this and this only:
"    ftypisom   isomiso2avc1mp41   free    mdat"

I have tried altering the rate (adding -r 25 for example) but that makes no
difference.

The non problematic (i.e. don't have to muck about with probesize) streams
save in whatever format without problems. So, again, confusion!

Hope you can help,

Pat

This is ancient (and broken), please see http://ffmpeg.org/download.html 
for supported versions, current git head is always strongly recommended.

(Backtrace for crash missing.)
(When reporting problems, always try to avoid using external 
libraries like x264 and libvo, it makes reproducing problems 
more difficult.)

I already wrote that there is some confusion between FFmpeg and 
the server you are using concerning timestamps, just look at 
the ffplay output.

This is an intentionally broken version of ffmpeg with several 
hundred known bugs, some of them security relevant. We therefore 
cannot support this, please see http://ffmpeg.org/download.html 
for supported versions.

Hi,

I downloaded the latest git checkout of ffmpeg and tried converting
mp4 file to h.264 using this command :

ffmpeg -i h264.mp4 -c:v copy -bsf:v h264_mp4toannexb -an out.h264

I got the following error:

Subject: [FFmpeg-user] Mixing audio tracks
Message-ID: <CANZNk82+Q8WXmA83D3c9-xyRTtdTZQDuAoBQs7r8aNF97rhhng@mail.gmail.com>

Hi. I fail to mix two audio tracks using ffmpeg utility.

First i tried with recently added -af flag, but it looks unclear how
to address different input files, and is it is possible at all. See
Listing 1.
Then i tried -f lavfi, but having confusion about usability of it.
amerge filter tells on merging two mono files "Inputs overlap: output
layout will be meaningless". Also, before, i tried the same without
adding "pan" filter, with original stereo channels layouts. See
Listing 2.
Do i miss some point, or is that really not finely usable case of
ffmpeg utility? Or some regression?

Hi there

The subject line pretty much says it all. That command was taken 
straight out of the ffmpeg documentation... wierd thing is the command:
-vf lutrgb='g=0:b=0'
works perfectly... which is also out of the documentation under the same 
section.

Any ideas why this is happening or how the gammaval should be inputted 
please?

AAH!
Sorry, managed to acheive what I want with
-vf lutrgb='r=gammaval(2):g=gammaval(2):b=gammaval(2)
but this also works and does exactly the same:
-vf lutrgb='y=gammaval(2):u=gammaval(2):v=gammaval(2)

At first I guessed it was because the video format I'm using is using an 
rgb lut as opposed to yuv...but then why when I set y=gamaval etc as 
opposed to r=gamaval does it still work. Do yuv = rgb?

Sorry for being such a noob :P

-af works only for a single input and a single output. For several inputs or
outputs, you need to use -filter_complex.

That is probably normal, since your source tracks have the same channels.

That should not have happened. I will try to look into it shortly.

There is no h264 video in you mp4 file that you could filter in 
h264_mp4toannexb or write to h264 raw stream.

Adding to what Carl already told you:

Your input file does not contain h264 video, it contains 'mpeg4 part 2' 
video. So you can't just *copy* the video stream out of this file and 
expect to have a valid h264 file.

 >     Stream #0:1(eng): Video: mpeg4 (Advanced Simple Profile) (mp4v /

This line will say 'Video: h264' if your input file actually has an h264 
video stream. In that case, your original command line should work.

If your ffmpeg was compiled to support libx264, you can transcode from 
mp4v to h264:

ffmpeg -i infile.mp4 -an -vcodec libx264 -crf 23 outfile.h264

It should be fixed.

OTOH, your command line is rather nonsensical: the "pan=1" downmixes each
input to mono before the merging, which is probably not what you want, and
furthermore makes it silent since you did not put any coefficient.

I don't get the point, why i can't merge two mono channels for further
mixing. Or how should i show my intention to lavfi.

You can. But the stream after merging and before mixing will have two
front-left channels and two front-right channels, this is not a valid
channel layout. af_amerge will therefore pick any channel layout with four
channels and stick it on the stream, just because a channel layout is
mandatory.

Please read the documentation of amerge, it explains that. If you find it
unclear, questions about its wording or suggestions to make it clearer are
welcome.

Hello Carl,

Thanks for your reply.
I used the command that you sent:
ffmpeg -i infile.mp4 -an -vcodec libx264 -crf 23 outfile.h264

and it worked perfectly fine.

Thanks and regards,

1) http://ffmpeg.org/faq.html#How-can-I-join-video-files_003f lists
MPEG-1, MPEG-2 PS, DV as the containers that support concatenation.

2) The same page lists an option for using named pipes that I have
found useful for exactly the same use case you are describing.

I believe it is true that ffmpeg will have to parse the video until
minute 20 to start processing minutes 20-30.

Carl,

Had to change email addresses for this list as it suddenly stopped working
(FFMPEG's mail server suddenly thinks the domain nerdy.co.uk doesn't exist)
- anyway apologies for the delay in getting back to you.

The timestamps are most likely a problem at the encoding stage. The server
you're connected to is an up to date Windows Media server. The problem for
me with changing the encoding is firstly finding the fixing the issue,
distributing the software and getting people to use it (each broadcast is by
a different person somewhere in the world). If I can hack it within FFMpeg,
all the better for me, for now.

I note if I ask FFPlay to sync to the video rather than audio it works in
this case (i.e. ffplay -i "mmsh://209.105.232.35/cssaitek1" -sync video) -
though I note there's no probesize option I can use to make it play quickly.

Is there an equivalent in FFMpeg (I can't find it), so I'm at least getting
some data into the file. Something to just say 'disregard the discrepancy'
in timestamps - as I think this would only occur in streams where there is
no audio data anyway.

Again, apologies for being a bit thick on this, as I personally am testing
this with the windows binary, how do I get a backtrace? It crashes with a
windows dialogue box saying FFMpeg.exe has stopped working and the only
available traces are a windows memory dump and some rubbish hardware info
XML which would be sent to Microsoft if I selected to do so.  It's not a
crash which gives me any output in the command prompt window.

> (When reporting problems, always try to avoid using external libraries

It only crashes when I try to transcode to anything other than JPGs or WMV.
If I try .avi, .flv, .mp4, etc it does this crash. So I can't really get a
backtrace if I don't issue a transcode option. The 'non problem' streams
transcode to any of these formats without issue.

I think what you say about the timestamps is definitely key to helping solve
this. Sorry to send 2 ahead of a response.

Subject: [FFmpeg-user] Removing metadata from MOV files
Message-ID: <CAN0LTaPr=0MhV7mKt_nhNqHvMpBvVB7c+zxFq_LuJHN+KXfWpw@mail.gmail.com>

I'm trying to remove all metadata from a MOV file I have. For earlier
(?) versions of FFmpeg, the map_metadata -1 switch should have
stripped all metadata, but it doesn't appear to do so anymore.
The metadata record has gone down from ~80 lines to about 50, but
still things like creation_time etc. are preserved. According to this
post <http://askubuntu.com/a/139581> even these timestamps should be
deleted, but this used an ancient FFmpeg version.

So, how can I remove as many metadata entries as possible?

Best regards,
Werner Robitza

Yes that works in ffplay (I still get the 3 min delay on that stream, don't
you?).

No, with "works fine", I meant that it plays a second or two after 
I started the ffplay command.

Ok thanks for knowingly baffling me. I try to explain I'm a novice. I
understand - I guess you're trying to be helpful. I'm asking questions
within my scope of knowledge and you intentionally avoid helping
specifically what I ask, instead pointing out what is missing in my
responses, where clearly you're able to replicate my problem. Is this a
game? I'd be happy to pay but I thought that might be a faux pas in itself -
can't win.

Obviously I am not a developer, I have to outsource stuff. I understand
enough so that if a problem can be hacked around I can pass on the relevant
info to a developer. I appreciate you appear to want to help, but I guess
you'd rather make it intentionally more difficult for me.

Chris has this matter - and i have a similar Q - that may serve chris.
I seem to recall that the order matters / placement in the command matters.
meaning there is an ideal location for the -ss Num & the -t Num

example:
ffmpeg -i G:\location1\0045.mpg -ss 00:30:13:28 -t 00:00:02:28 -target 
ntsc-dvd -vcodec copy -acodec copy G:\location2\0045-023.mpg
is calling -ss Num & -t Num after the -i  the best place
is theer a location in the command that makes this '30 min seek' quicker?
and what would that be?

Basically  of    ffmpeg -ss Num -t Num -i <file>    or     ffmpeg  -i 
<file> -ss Num -t Num
is one superior in performance than the other?

thanks

You don't. The only people likely to be equipped to do this are  
professional software engineers. I should point out that Carl Eugen knows  
this full well and is being deliberately obstructive.

What Carl Eugen is doing here is asking you to compile a special version  
of ffmpeg using only parts of the source code that went into making up the  
version with which you're working. Again, this is not something you will  
be able to do unless you're an experienced software engineer (and again,  
Carl Eugen knows this very well and again, he's being deliberately  
difficult).

Carl Eugen, please don't ask people to do things that you know they're  
unlikely to be able to do.

It is considered rude.

I am not able to reproduce (two of) your problem(s).
ffmpeg does not crash here, the reason might be that my FFmpeg is not 
compiled with x264 support, but I don't know because as far as I know 
you did not test without -vcodec libx264
(Note that crashes are important, so there is a high chance that 
the crash is fixed once it is either reproduced or a backtrace is 
provided.)

ffplay works fine here (without any waiting), as long as you do not post 
your ffplay command line together with complete, uncut output, I cannot 
explain why it works for me but not for you.

ffmpeg does not convert the problematic streams here, I do not know 
why, but if you look at the ffplay console output, it indicates 
that FFmpeg is unable to correctly read the timestamps
(I tried to explain that in my very first mail iirc), that 
seems like a reason, and I do not know how to fix it.
(I tried -copyts and it did not help.)

Yes.
ffmpeg -ss n -i file seeks to n (if this is supported) 
which usually works without any delay
ffmpeg -i file -ss n decoder the first n seconds which 
can take considerable time.

It does not crash when encoding the non problematic streams utilising
(presumably) the libx264 codecs when outputting a .flv or .mp4. 

As you pointed out, there does seem to be an issue with timestamps.

I only know what I see. In FFplay, I get the following with:

Unlike the non problematic streams, this scrolls up in the window rather
than replaces the same line while FFplay window plays stream. The timestamp
in the stream indicates it's playing from the immediate aftermath of the
command and not from the 3 minute point.



So this is when I tried:

ffplay -i "mmsh://209.105.232.35/cssaitek1" -sync video

The above line is all that was on the screen when I ctrl+c'd it. It did not
scroll up like the other method.

I know that's hardly scientific, but the 'non scrolly' view is what I get
with a non problematic stream also, so in my mind at least, it 'means
something'. Hence, my assumption that if I could replicate the '-sync video'
option within ffmpeg, I could get some desired output?

Sorry for mildly snapping before. I appreciate the support and understand
it's all done on a completely voluntary basis. 

I've seen the streams all work in various apps which utilise FFMpeg
components on different devices, so fundamentally I believe the probesize
thing has fixed a great deal (the problem streams take 3 minutes to start on
the apps I've tried) - I guess I'm trying to just make sure I can do some
transcoding of some kind here before instructing developers of any special
requirements for FFMpeg. Saves money them scratching their heads (and in my
experience not even delving this deep and giving up)

What's mildly odd is that it will play in FFPlay and look fine - so if it's
able to do that, why can't those frames be transcoded? I know it sounds
incredibly simplistic from me, but obviously it feels -so close- to working
it's head scratching to say the least.

If there's any specific ffmpeg/ffplay outputs which would help, just ask.

Thanks,

Pat

Dude,
I am NOT sending any spam. I don't have the time or the inclination to do so. Do a little bit of research on email security or lack of it.

If I have to send spam, why would I use my own email address to do so?

It does not matter the input: If FFmpeg crashes, there is a serious 
issue, as said, it can (normally) be either fixed if it can be 
reproduced (I cannot reproduce it but I may miss something since 
I have not seen console output when it crashes without -vcodec 
libx264) or if a backtrace is provided. Please understand that I 
am not asking you to recompile FFmpeg, I am simply explaining why 
the crash is unlikely to get fixed atm.

> ffplay -i "mmsh://209.105.232.35/cssaitek1"

Why aren't you using -probesize?
Without, I also get a delay (actually, I suspect I get a delay, 
I never waited long enough).

[...]

> What's mildly odd is that it will play in FFPlay and look fine

I believe it actually is not correct (= there is A/V desync when 
you play the stream with ffplay), but because of the nature of the 
streams, you don't (easily) see it.

Clearly I had been typing something wrong, sorry. I tried it again and yes
it works pretty much straight away.

I certainly never see the video frames jump around in the wrong order and
like I say, the problematic streams I believe are those where at the
encoding process there is no data flowing within the audio stream so one
would not know or care if that track was out of sync.

I understand the need to trace the error in the transcoding part - going to
have to figure that one out myself I guess.

(Command line and complete, uncut console output missing.)
ffmpeg -i is supposed to give you many informations about the input 
file, including the codec used to encode.

you can use MediaInfo to know information about a media file, including
codec, bitrate, resolution, sampling, audio channel configuration, etc.

Hi Carl, this is the output for the following files: video3.avi and
video1.avi

 ffmpeg -i  video3.avi

However if I try to concatenate them with mencoder it doesn't allow due to
differents codecs.

Thanks for your help.

as you can see, there is fps different
maybe you can add -ofps 24000/1001 in mencoder

Thanks, then it isn't a different codec issue. I'll try it tomorrow.
However it could be better to have a standard fps/codec for every file to
be concatenated.

Why do you think that MEncoder (that is an unmaintained application 
for many years) known the codec better than FFmpeg?

Are you sure this is supposed for avi files with different frame 
rate?
Did you try ffmpeg's concat protocol?

Actually not, the whole information thrown by the command was sent but the
ffmpeg version and other related stuff which hadn't to do with file
information. I supress in order to give a clean output.

Actually I don't which is better. I am clearly new in this subject. Since
Mencoder is widely used I didn't thinks it could be a problem.
In fact it concatenates well unless files with different codec/fps.

If you meant about Mencoder it seems it is not, however the error message
specifies a different codec not frame rate.

No, I didn't. I'll tray it later then. Thank for your suggestion.

I did the concatenation according
http://ffmpeg.org/faq.html#How-can-I-join-video-files_003f

mkfifo intermediate1.mpg
mkfifo intermediate2.mpg
ffmpeg -i input1.avi -same_quant -y intermediate1.mpg < /dev/null &
ffmpeg -i input2.avi -same_quant -y intermediate2.mpg < /dev/null &
cat intermediate1.mpg intermediate2.mpg |\
ffmpeg -f mpeg -i - -same_quant -c:v mpeg4 -acodec libmp3lame output.avi

The cat doesn't work, there's a similar command in Mencoder. It complains
about different frame rate and/or codec.

However my original question was if I could know the file avi codecs. Is
the ffmpeg -i file.avi correct command?

Thanks

Rossana

Message-ID: <CAPmJznXeE=O1R4HGdbhrhD4DkMGqB10u_CFcS4vOefmh0ffGvg@mail.gmail.com>

Hi,

I have a question regarding the use of h264 in a Debian server.
My server provider told me that libx264 is not stable in Debian, so instead
they've installed h264. As far as I'm concerned, libx264 and h264 are the
same, am I wrong?

The following command that it worked perfectly in a Freebsd server, it's
not working on a Debian one.  They say that I should use another codec that
is not h264 although it's installed (?), so I feel they are confused.

So what's the correct way to declare  -vcodec libx264 in Debian then?


$output=runExternal($ffmpeg_path."ffmpeg -y -r 7 -i ".$servpath."img%d.jpg
-r 7 -b 1000K -vcodec libx264 -flags +loop -me_method hex -g 250 -qcomp 0.6
-qmin 10 -qmax 51 -qdiff 4 -bf 3 -b_strategy 1 -i_qfactor 0.71 -cmp +chroma

Thanks!

so, ffmpeg already installed, doesn't it?
try ffmpeg -codecs
it will list all available codec.
search for 264 with Encoding support and it will print out what paramater
should be supplied as codec

Subject: [FFmpeg-user] Query reg thumbnail image of a video
Message-ID: <1DDBAED6D9C92D428753FAC1CA031128282546A2@chnshlmbx13>

Hi,

I am using the latest FFmpeg version in my CQ5 to play videos. This is been used in UNIX  server. The video gets played properly,
but I don't get the preview image (thumbnail) for few videos.
The one video which shows the thumbnail has the same renditions as that of the other which doesn't show a thumbnail.
Here both videos are of .wmv format. Why is the thumbnail not shown for few videos?

Below are the list of files that are created inside the renditions folder for both set of videos

Cq5dam.thumbnail.140.100.png
Cq5dam.thumbnail.319.319.png
Cq5dam.thumbnail.48.48.png
Cq5dam.video.firefoxhq.ogg
cq5dam.video.flv.320.240.flv
cq5dam.video.hq.m4v
original



Thanks and regards,
Sujith.

Thanks!
The think is that I don't have access to their server, so I can't do it
myself. I asked them already, we'll see how it goes.

Does someone know about a server provider that has ffmpeg, qt faststart and
libx264 tested and working?

Joana.

I meant you could try the new concat: protocol of ffmpeg 
that does not need "cat" anymore.

You've failed to grasp (again) that the important word in Pat's
sentence that I didn't notice in his earlier emails is "Windows".
Sensible OSs don't prevent users from helping developers like that.

s/experienced//

Again this is only really an issue on Windows (and somewhat on Macs),
because decent compile environment that doesn't cost the earth is
hard work to set up.  On Linux, it's trivial.

But in this case you're just plain wrong.  Carl Eugen isn't asking Pat
to recompile anything.  He's asking him not to use external libraries,
i.e. not to select the x264 codec, which is a rather different
proposition.  I'd suggest that you owe him an apology, but knowing
how poorly you take his rather abrupt usage of English, I'm not
holding my breath.

You can use ffprobe -show_streams for getting the codec name used in
the streams (along with more information), in a parser-friendly way
(check also the -print_format option).

Peter:

The mail headers seem to confirm that these messages *are* coming from
your yahoo email account.

Change your yahoo email password.

Hopefully, that will stop further problems.

Almost every day I am receiving some of these "Yahoo security mega alert about to close your account if you do not login on the fake login page on that weird looking non yahoo URL".
The fact is that they all go in my spam folder... So I have no idea how people gets fooled by these.

that is not the point

the point is that someone who's mail-account is hacked
has to fix this IMMEDIATELY an not after some days and
there is no excuse that this happens again 24 hours
after a off-list mail

also fact is that many people are whitelisting their
mailing-lists on spam-firewalls because especially
on technical lists they are otherwise often catched
as false positives

however: "Dude, I am NOT sending any spam" is after two
days of spamming a reaction with no excuse and if some
foreign hacker is using your account does not change
anything in the fact your are responsible for it

My understanding is that debian is using a fork of ffmpeg, not the 
"real" ffmpeg.

On this list, we provide help for the real ffmpeg, but not for the fork.

There is no way to know what "we installed h264" means. If instead they 
said 'x264', that means they installed a standalone application that 
focuses mostly on h.264 encoding.

There are millions of hits in google for how to use that app. You can 
start at http://x264.nl

You need to go to the fork's mailing list for help with that.

It's called a "Joe Job" 
(http://en.wikipedia.org/wiki/Joe_job)

It's relatively easy to send email appearing to be from a 
particular email address, without that user's username and 
password.  I was sending people email from god at heaven.edu 
in the late 80s.  See also email spoofing 
(http://en.wikipedia.org/wiki/E-mail_spoofing)

A fairly popular technique amongst spammers is to roll 
through mailing lists and look at the users' email 
addresses, then use those addresses to send spam to the 
list.

Subject: [FFmpeg-user] supporting arguments for FFV1 encoding
Message-ID: <C94BB24E-93F0-4DFF-98C3-863902566E68@mac.com>

Hi,

I am testing using FFV1 encoding and have some questions on use.

When encoding to >8 bit (like ffmpeg v210.mov -c:v ffv1 ffv1.mov) I get this warning:
[ffv1 @ 0x7f83a1850a00] bits_per_raw_sample of more than 8 needs -coder 1 currently

Could -coder 1 be the default in circumstances like this? Is there a disadvantage to using -coder 1? In other cases ffmpeg will provide an error and no output when the user needs to provide more information to make a decision about the encoding. In this case there doesn't seem to be any significant decisions to be made, the user just has to add -coder 1.

With FFV1 version 3 specifically, when I run a command like this:
ffmpeg -y -f lavfi -i testsrc=duration=5 -c:v ffv1 -level 3 -strict experimental out.mov

I get the error:
[ffv1 @ 0x7fd879850a00] Unsupported number 0 of slices requested, please specify a supported number with -slices (ex:4,6,9,12,16, ...)

If I specify slices manually, -slices 4, then the encode will work. To make this simply could ffv1 version 1.3 use a default number of slices but still provide the option for tweaks.

I grasp that very well. I suspect our friend Mr Hoyos doesn't. You would  
do well to remember that

> Sensible OSs don't prevent users from helping developers like that.

I'm not interested in an OS war. If you don't want to support windows  
because you have some sort of political problem with it, please ask people  
to stop making windows builds or at least make it clear that you can't be  
bothered to support anything but linux.

Please, linux people, I know you struggle to understand this, but this is  
after all a user list, for users, not for high-level software engineers  
with years of experience. Compiling software, on any operating system, is  
a topic for professional software engineers, who are likely to have the  
experience and training necessary to solve the various problems that will  
very certainly come up.

Doing it on linux requires you to be an expert in makefiles, configure  
scripts, ffmpeg itself, the API to all the external libraries it uses,  
their configure and make files, and to unpack the right versions of the  
right files and folders into the right places, in the right version of the  
right OS with the right patches, updates and hardware available. And if  
any one of these things is even slightly out of place (which it will be)  
the process will fail, and you'll find yourself up to your neck in some of  
the world's most poorly-documented C and assembly code and the pile of  
shell scripts that Linux people like to pretend is an IDE.

> He's asking him not to use external libraries, i.e. not to select the  
> x264 codec

That's not my understanding of "don't use external libraries", but that's  
my point: I'm not a software engineer. It's difficult to ensure that the  
thing won't pull in some bit of code from an external source at some  
point, no matter what you ask it to do. Unless you understand its internal  
workings, of course. Which I don't, and I suspect the OP doesn't, either.

> I'd suggest that you owe him an apology

Of course you would.

My problem with Carl Eugen Hoyos is that he doesn't really try to help  
anyone; he simply demands that people do things he probably knows they  
can't do. This is arrogant sophistry, it's idiocy, and it's sadly exactly  
what I've come to expect from the open source world.

You have got to stop assuming that everyone who appears on this list is an  
ffmpeg developer of ten years' experience who knows how to cast the right  
bones, chant the right incantations, etc. That, or close the list and just  
have the devel one, and the rest of us can rely on forums.

What's not OK is to be rude to people on the basis that their questions  
are too basic for you. You aren't required to be on this list, and you  
aren't required to try to help people. If you can't do so civilly, don't  
do it at all.

bullshit

i am building ffmpeg / x264 and most deps since years as RPM and
have not any knowledge in C/C++ nor ever touch a makefile

your only problem is that you are proven an igornat
troll and have no education about anything ontopic here

the only arrogance and idiocy is coming from you

how in the world do you imagine can a developer debug
any foreign binaries? if as example someobne is using
a stoneold build from whatever source he should complain
to the packager and not to the upstream developers

Proof, if proof be needed, that any internet conversation, no matter how 
earnest and pure its original intentions or how intellectually based its 
original purpose, will eventually turn into a playground debate about 
who has the biggest dick, and whose mum is the fattest.

I wished I lived in a Pixar animation instead of this rancid society we 
call modern life.

so buy adobe and be happy with it!

who do you think you are to demand that upstream developers
which provide the code for free are debugging binaries
they do not know?

if you want help for free you are not really in the
position to say how it has to be provided

especially as long are this are NOT your questions
where you are trolling and offending upstream
developers!

The hidden assumption here of course is that everyone here has (near)

that isn't the case, particularly for the majority of the people

Subject: [FFmpeg-user] WMV conversion for Powerpoint failing recently?
Message-ID: <201205241759.01183.ffmpeg-list@dubistmeinheld.de>

Hi,

I used ffmpeg to convert videos to WMV (in Linux) and then embed them in 
Powerpoint (in Windows)

Since a couple of weeks, the conversion still succeeds, but when I embed them 
in Powerpoint, the WMV videos are not playing anymore and sometimes the 
computer freezes. Playing fine in VLC.

Is anyone experiencing the same problem?

I use the following syntax:
/usr/local/bin/ffmpeg -i 'test.mp4' -vcodec wmv2 -acodec wmav2 -ac 2 -qmin 6 -
qmax 8 -b:a 128k -ar 44100 -r 25 -nostats -y 'test.wmv'

Message-ID: <CAEnqZEXx8xOsAnJedrBpji5HyG+p7xHfWcLFOOvaTvc6VwuJ=Q@mail.gmail.com>

Hi,

I have tested libvo_aacenc as a redistributable aac encoder but
recently noticed that there are audible quality differences compared
to a better aac encoder even at rather high bit rates such as 192 or
256k.

I doublechecked if it was the right encoder that was used as opposed
to the internal one and the bitrate and both are correct. Am I the
only one noticing this or has anyone else had quality problems with
libvo_aacenc? Any special CL parameters I'm not seeing?

Thanks in advance,

Robert

;-((
Does the output video also fail to play with Windows Media Player 
or only inside Powerpoint?
Is this also reproducible with
samples.ffmpeg.org/V-codecs/SVQ3/Vertical400kbit.sorenson3.mov 
as input? Or is your input file needed?

Am I correct that you are unable to run git bisect?
Could you at least tell a version that still worked (and one 
that fails)?

Thank you, Carl Eugen

Can you give it up and move on? Flooding a listserv with irrelevant messages IS spamming.

I have already changed my password, just in case.

I've said it a million times.

Nobody is required to do anything.

What you are required to do is be polite.

Non-programmers are not subhuman filth to whom it's OK to be rude.

Jeez. Can we take this idiot off the list? Looking at his other messages on the list, he has nothing constructive to offer.

If only you could use all the free time you have in development of ffmpeg code...

Looking at your past behavior, I am sure you will come back with some more lame remarks. I am adding you to my ignore list.

are you now totally crazy or why do you idiot reply
to a offlist-mail with TWO copies, one to me
and one to the list?

this proves one more time that you are fucking too stupid
to use the medium email - i do not need a private copy
since i receive the list

again to understand:

if you would have shown reaction after my first OFF-LIST
mail my yerstadys abuse-mail would never have happended

you are a perfect example for a real idiot

Subject: [FFmpeg-user] FFmpeg 2-pass libx264 encoding with php? possible?
Message-ID: <1337548739351-4647274.post@n4.nabble.com>

Hello,
maybe somebody of you can help me out!
My problem is, i need to convert many movies as they come to either mp4 or
flv to be able to stream(!) perfectly afterwards. I don`t know anything
about the videos before they get to encoding, and the script should be run
by Cronjob automatically. And now i am experimenting a lot with different
FFMPEG settings to achieve this!

The latest info i got was a HQ 2pass encoding technique-as i am not having
the preset for HQ availiable i had to search for the whole shell command.
These are the commands which should be done, but FFMPEG is stopping without
a reason, and the output file has a size of 0 after finishing. I watched the
process and have seen that the filesize goes up to the same size it would
have when i just do the pass 1 and then back to zero and finishes: no output
nothing.

for info: if i do each command seperatly they work smoothly!


$convert_call_pass_1 = $ffmpegPath . " -y -i " . $video_to_convert . " -r
30000/1001 -b 2M -bt 4M -vcodec libx264 -pass 1 -vpre fast_firstpass -an
-passlogfile passlogs/passlog_ffmpeg " . $converted_video . " 2>&1";

$convert_call_pass_2 = $ffmpegPath . " -y -i " . $video_to_convert . " -r
24000/1001 -b 6144k -bt 8192k -vcodec libx264 -pass 2 -flags +loop
-me_method umh -g 250 -qcomp 0.6 -qmin 10 -qmax 51 -qdiff 4 -bf 16
-b_strategy 1 -i_qfactor 0.71 -cmp +chroma -subq 8 -me_range 16 -coder 1
-sc_threshold 40 -flags2 +bpyramid+wpred+mixed_refs+dct8x8+fastpskip
-keyint_min 25 -refs 4 -trellis 1 -directpred 3 -partitions
+parti8x8+parti4x4+partp8x8+partb8x8 -an -passlogfile
passlogs/passlog_ffmpeg " . $converted_video . " 2>&1";

exec($convert_call_pass_1, $output);
exec($convert_call_pass_2, $output);

What am i doing wrong? is it wrong to call both execs one after another?

Is there a better solution for the problem with different incoming movies?
mp4 encoding is not a must...could also be flv!

Thanx in advance!
Surekin

Message-ID: <8944928500.20120521224944@io.ua>

Hi,

Could somebody explain whats wrong with the duration detection: "12:08:10.44"?

There are two outputs from the same video below: ffmpeg and MediaInfo.
MediaInfo gives "1h 56mn" for the duration - its OK.

Thanks in advance!

Subject: [FFmpeg-user] Wrong duration detection by ffmpeg
Message-ID: <952255890.20120523092730@io.ua>

Hi,

Please, explain whats wrong with the duration detection: "12:08:10.44"?

There are two outputs from the same video below: ffmpeg and MediaInfo.
MediaInfo gives "1h 56mn" for the duration - its OK.

Thanks in advance!

Quick note from phone: i am seeing this with aac audio and h264 video through mpegts muxer using udp transport. I've been able to mitigate it sometimes using codec:a libfaac. Source is a hauppauge hd pvr.

It does not crash when encoding the non problematic streams utilising
(presumably) the libx264 codecs when outputting a .flv or .mp4. 

As you pointed out, there does seem to be an issue with timestamps.

I only know what I see. In FFplay, I get the following with:

Unlike the non problematic streams, this scrolls up in the window rather
than replaces the same line while FFplay window plays stream. The timestamp
in the stream indicates it's playing from the immediate aftermath of the
command and not from the 3 minute point.



So this is when I tried:

ffplay -i "mmsh://209.105.232.35/cssaitek1" -sync video

The above line is all that was on the screen when I ctrl+c'd it. It did not
scroll up like the other method.

I know that's hardly scientific, but the 'non scrolly' view is what I get
with a non problematic stream also, so in my mind at least, it 'means
something'. Hence, my assumption that if I could replicate the '-sync video'
option within ffmpeg, I could get some desired output?

Sorry for mildly snapping before. I appreciate the support and understand
it's all done on a completely voluntary basis. 

I've seen the streams all work in various apps which utilise FFMpeg
components on different devices, so fundamentally I believe the probesize
thing has fixed a great deal (the problem streams take 3 minutes to start on
the apps I've tried) - I guess I'm trying to just make sure I can do some
transcoding of some kind here before instructing developers of any special
requirements for FFMpeg. Saves money them scratching their heads (and in my
experience not even delving this deep and giving up)

What's mildly odd is that it will play in FFPlay and look fine - so if it's
able to do that, why can't those frames be transcoded? I know it sounds
incredibly simplistic from me, but obviously it feels -so close- to working
it's head scratching to say the least.

If there's any specific ffmpeg/ffplay outputs which would help, just ask.

Thanks,

Pat

OK boys that was fun but that's going a bit too far.

Reindl: we all are "real idiots" in a way or another, a bit of
tolerance is required even if someone is lacking what in your eyes is
elementary technical background or netiquette knowledge.

Also that language and that attitude is *definitively* not acceptable
in this list, so I'm going to ask the list administrators to moderate
you in case I read another mail from you in the same tone.

Everybody has his problems, someone may miss a mail or even an hacker
sabotage of his mail account, and they may have not the time and the
energy (or even the knowledge) to babysit their computer 24/7.

Peter: fix the issue as soon as possible and try to avoid it to happen
again.

All: in these cases please directly contact the list administrators,
whose contacts can be found here:
https://lists.ffmpeg.org/mailman/listinfo/ffmpeg-user/

this way you achieve the double purpose of avoiding spamming the
mailing list and avoiding spreading flamefests like this, which
usually don't help the involved people in any way. You may have fun
(well a flamefest from time to time is fun to read and breaks the
boredom of technical threads), but until a point, which I think has
been reached right now. Please continue the flamefest in private if
you really enjoy it.

Message-ID: <CALEXE5=2s=Zb=d_O+U=2AcsUT0xqAQuNJCgeF3Sjt+Enkpfy4w@mail.gmail.com>

Hi,

I'm mixing audio for a movie on Ardour (an audio editing software), which
can't export to AC3, but it can export multiple channels to other formats,
e.g. FLAC. So I have it encoded in FLAC with 5.1 surround sound. I'd like
to use ffmpeg to convert it to AC3 at 48kHz and 640kb/s with 5.1 surround
(Dolby Digital).

Here's what I have so far, but I'd like to change (or make sure it's
correct) the channel layout.

ffmpeg -i Session.flac -s:a 48k -ab 640k -acodec ac3 -ac 6 Session.ac3

Which returns

That leads me to believe that it's using a channel layout of "5.1(side)"
(maybe assuming the surround speakers are on the sides, rather than behind,
as I want). Also, it automatically sets the sample format to "flt". Is this
what I want, or how can I change it?

Thank you!

Please compare with a random 5.1 Dolby stream from DVB or DVD, 
it should be identical.

It feeds "flt" into the encoder that outputs "Dolby".
There is also a (slower) Dolby encoder that uses "s16" as input, 
but it has no advantage.

Hi,

 

    We are developing a video rendering app on Android using ffmpeg. The app
crashes in avcodec_decode_video2 every now and then. We are releasing the
decoder only once after it comes out of the rendering screen. Does the
decoder need to be initialized every time the video is started and released
every time the video is stopped?

 

Thank you,

no, if someone get a OFF-LIST reply in some countries
he is even not allowed by law to make a reply public
and since MANUALLY action is required to act like he
did this is the perfect example for "idiot"

> Reindl: we all are "real idiots" in a way or another

no, there is a difference between missing knowledge
and pure ignorance

it needs no elementary technical background to hit the reply-button
in a mail-client instead "reply all" or paste another RCPT

if this is "technical background" for someone he better does
not use email at all because of all of the millions of spam
mails 99% produced by hacked accounts or computers (zombies)

and now listen and try to understand what i will explain you!

you are part of the problem like also "ianm at brick.net" who thought
he needs to exlain me why it can be a spoofed message!

do you guys not realize that there is NO SINGLE REPLY FROM AYBODY
needed on the list if you are not Peter Tap and even if you
are Peter Tap there would have been only one reply needed which
shows that the problem was understood and fixed

the only reason why i included the list in my abuse mail was to
prevent 500 or more other people from writing also a abuse-mail
for the same message

this is also the wrong answer since the origin was verified

Message-ID: <1337948347.81450.YahooMailNeo@web87705.mail.ir2.yahoo.com>

I have some streams in h264/aac and i have had to double the probesize value to get ffmpeg to recongise the audio/video correctly.

As this is a MPEG-TS container and I know the values of the audio/video pids and their formats is there a way via the commandline to tell ffmpeg this info without going through the probing?

You have been on this list for years, yet you post a question like this 
without an ffmpeg command line?

In my experience, this symptom occurs only with network or pipe input. 
So no one can give an accurate answer since you did not provide any 
information about that.

Sorry meant analysizeduration, had to change it to double the 5000000 ffmpeg normally uses, and i did surf and check for answers, but with the speed ffmpeg changes most searches turned up outofdate stuff, hence coming to the list

ffmpeg -analyzeduration 10000000 -i xx.avi -f mpegts -y a.ts

Is that a good enough command line, the problem is the source material has the tendency to only give the audio stream as the -x264opts keyint are 75/100 depending on the stream coming in.

Subject: [FFmpeg-user] White frames at the end
Message-ID: <CAExGtT6HOqQ=wx2W=+v58k7LBmCu9UakM4bSMT-nu_msAghoXw@mail.gmail.com>

Greetings,

I've been trying to use ffmpeg to do a mov to mov conversion (with
different size and bitrate in the output, otherwise it'd be useless of
course).

However, the output file has some white frames at the end. Running ffmpeg
-i on both the original file and the resulting file, so I can see the
details of the codification, reveals that the latter is 0.03 seconds longer
(pasting raw output below).

By googling I found this (http://forums.creativecow.net/thread/291/681).
But using the -shortest parameter doesn't change anything, same results.

Could any of you, please, give me a clue or point me to a resource to
diagnose the problem? Many thanks in advance.

Here you have raw ffmpeg output:

-
Compile

$ ffmpeg -y -shortest -i (input file).mov -ar 44100 -b 1500000 -f mov -r 25
-s 640x360  (output file).mov

Sorry, but I am even more confused. Your orignal question was about 
reading an mpeg transport stream. So why does your command show an .avi 
input file?

Further, increasing 'analyzeduration' for an .avi file *should* have no 
useful effect. AVI has a header at the start of the file, so no 
'analyzing' (scanning the bitstream) should be necessary to discover 
what stream types are present in that file type.

Please show us the output from 'ffmpeg -i xx.avi'

Hi all,
I use following command to get video from image

ffmpeg -loop 1 -r 5 -i input.jpg -c:v libx264 -preset slow -tune
stillimage -crf 24 -t 10 output.mp4

it is great for mp4

but when i use the following command to produce a MPG

ffmpeg -loop 1 -r 5 -i ../images/001.jpg   -tune stillimage -crf 24 -s
-t 10 -r 29.97  output.mpg

I always get a blurred video

Can some one please help me


Thanks in advance

I also do not understand your question, but if you provide a

Is this problem only reproducible if you use external libraries 
(libx264 and libfaac) or also if you encode using internal 
codecs (-vcodec mpeg4 -strict experimental -acodec aac)?

list.
The comple un-cut message seems to be too large Can I post such a long

So, the command I figured out (ffmpeg -i Session.flac -s:a 48k -ab
640k -acodec ac3 -ac 6 Session.ac3) works, but even though it does in
fact have 6 channels, it plays in stereo. Am I missing an argument
that maps the channels correctly? I also tried converting from a wav
version of the file (that's also encoded in 5.1 surround, and plays as
such), but with the same result.

Does anyone have any idea what I'm missing?


Thanks,
Chase

-tune stillimage -crf 24 have no effect for mpeg1video, so 
please remove them. Either use -b:v to specify a bitrate 
or -q:v to specify a constant quantiser.

This seems unlikely / difficult to understand.
Above command does not "play" anything, so I assume you used 
something else to test the resulting file. What was it?

And a sample will probably be needed, or you use 
samples.ffmpeg.org/multichannel/6_Channel_ID.flac to make sure 
we are talking about the same input file.

You should probably explicitly define the channel layout. Here are some notes from an internal app of mine that should assist in translating the various Dolby terminology into ffmpeg terminology:

ac3_center_dmix (-center_mixlev -ltrt_cmixlev -loro_cmixlev; float)
ac3_surround_dmix (-surround_mixlev -ltrt_surmixlev -loro_surmixlev; float)
ac3_copyright_bit (-copyright; 0 or 1)
ac3_dialnorm (-dialnorm; negative int)
ac3_original_stream (-original; 0 or 1)
ac3_dmix_mode (-dmix_mode; 0,1,2)

ac3_channel_l = 1
ac3_channel_r = 2
ac3_channel_c = 4
ac3_channel_lfe = 8
ac3_channel_ls = 16
ac3_channel_rs = 32
ac3_channel_lsb = 512
ac3_channel_rsb = 1024

-channel_layout: 1_0 = 4, 2_0 = 3, 2_1 = 11, 3_0 = 7, 3_1 = 15, 5_0 = 55, 5_1 = 63, 7_0 = 1591, 7_1 = 1599

And an example for converting a poly bwav into a fully formatted ac3 with metadata:

ffmpeg -i T-Vox\ Channel\ Ident.WAV -vn -acodec ac3 -ac 6 -ar 48000 -ab 448k -dialnorm -24 -dsur_mode 0 -original 1 -dmix_mode 2 -channel_layout 63 result.ac3

Hope that helps,
Josh

This is certainly a possibility, but I since I tested many 
(including unusual) layouts with ffmpeg and a receiver / 
hardware decoder and I do not remember a case where 
specifying the layout was really necessary:
Could you provide an example where it is necessary?
(except raw pcm input, of course)

There may be bug in the default behaviour that can be fixed.

To be honest, I don't have an example. Only many years of experience as a broadcaster that has led me never to trust anything associated with the words "default" and "Dolby" in the same sentence :)

We always explicitly define all metadata flags for every encode as its the only way to reasonably expect the playback behaviour to be appropriate, especially with regards to dialnorm, mixdown coefficients, and compression methodologies. I suppose explicitly defining the output format mostly stems from the use of Dolby's hardware encoders.

Thanks!

Thanks everybody! It turns out, Totem (the Gnome Movie Player) doesn't
recognize it as surround sound correctly, but vlc does.

There was only a small difference in ffmpeg's output to the terminal
with the different commands, that is not warning about not specifying
a channel layout anymore, and it says "5.1" rather than "5.1(side)".

I don't know if there's actually a difference in the outputted file,

It's in the metadata (channel labelling). In most cases, set top boxes and receivers will treat them the same, but by specifying mode 63, you've forced the metadata to match the standard Dolby metadata for an ITU 5.1 program stream.

I did notice that you utilized -24 as the dialnorm value, which was in my example, but isn't necessarily correct for your program. I would encourage you to measure the long term LEqA (Dolby) or ITU-R BS1770 loudness of your program in order to determine the actual loudness value in order to be presenting valid metadata and be in compliance.

Also, I provided a downmix value of 2, which causes the program stream to suggest (note: not necessarily enforce) a preferred downmix mode of Lo/Ro, which entails a simple folddown of the content to stereo. This is as opposed to Lt/Rt (which would be option 1) which causes a 90 degree phase shift to the surround channels prior to performing the folddown, and is designed to improve later upmixing should the end consumer's receiver be in Dolby ProLogic mode, but can cause other interesting artifacts due to the phase shift.

Yes, as odd as it sounds to hear that folks would take a stereo output of a device (which is actually a downmix of a true 5.1 program) and then run it through an upmixer afterwards, it happens more often than you'd think.

I won't argue that one mode is better than the other. It tends to be highly content sensitive. I would suggest you encode in both modes and compare the stereo mixdown output to see which provides a better experience. I tend to lean towards Lo/Ro for most of the mixing I do, especially if there is a great degree of discretely mixed 5.1 music as part of the program, but I'd encourage you to listen to both so you can understand the results and ensure the greatest portability of your final mix.

Take care,
Josh

Oh, I see. I've been reading through the myriad of ffmpeg arguments
that just set certain metadata options. I'll keep the -dialnorm option
in mind when I'm actually encoding the audio for a dvd/blu ray burn.

I guess you really have to guess what downmix option you want to use,
as I know my stereo surround sound system I use with my TV has tons of
options, e.g. Dolby Digital (not downmixed), Dolby Pro Logic, Stereo
Surround (downmixes to stereo, then mirrors R and Rs, mirrors L and
Ls, and combines both for C), and many more.

Thanks,
Chase

Oh yeah, there's a million awful things that home set top boxes and receivers can do to your mix.

Thankfully, most folks will either likely be listening to the 5.1 mix via Dolby Digital, or a stereo downmix (utilizing the mode described in your metadata, hopefully). If you create a ITU downmix in your DAW that folds C (at -3 dB) to L and R, and folds Ls and Rs forward to L and R respectively with a -3 dB gain reduction, and LFE at -6 or so to L & R, you can at least test the Lo/Ro option while you are mixing. At least then that version will be predictable. Without a plugin that mimics the Lt/Rt downmix process, that's much harder to guess.

So I'd set up a simple ITU folddown to check your mix against while mixing, and then use mode 2 downmix (Lo/Ro). At least that way you can hear that final result while doing the mix.

Take care,
Josh

Apologies for butting in - but you seem to have lots of experience with ac3.

Am I missing something obvious with ffmpeg, or is there no way to 
specify a drc profile eg. film standard.

It would be handy (for my ears at least) to reduce with metadata full 
range sources, but I can't see any encoder option for this. I know drc 
is implemented for decode - is there a way when encoding?

TIA
Andy.

Subject: [FFmpeg-user] Changing DAR without filtering file?
Message-ID: <1338146837954-4650500.post@n4.nabble.com>

Hi,

I have a very basic (and I fear possibly dumb) question that I would be
grateful if anyone had time to answer for me.

I have a number of h264 encoded videos at a 720x480 resolution which should
correctly be viewed with a 4:3 Display Aspect Ratio (DAR). However, the DAR
of the files is set to 3:2. I have found that I can correct this by using
the ?aspect command but this results in the whole file being filtered, which
obviously takes a while and will lead to me having to get my head around
lots more options. My question is, is there any way of changing the DAR
without needing to filter the whole file? Naively I thought this was
essentially header information on a file that could be changed simply on its
own?

Just in case it?s relevant, the command I?ve been using is of the form:

ffmpeg ?i InputFile.mp4 ?aspect ?4:3? OutputFile.mp4

(I also tried the setdar command but the result was the same.)

Thanks very much for any help.

Not that I'm aware of. I'd really like to be wrong about that though...

Do note that the dialnorm value plays heavily into how the decoder applies the drc profile (in terms of threshold values), so ensuring it is set correctly and accurately will improve playback when drc is enabled on the decoder.

I'm hopeful that someone else on this list can inform us of the variables/values to set the drc profile though...

Thanks,
Josh

Hello.

I have tried to compileffmpeg with both yesterday's and today's git
snapshot, but I get the same result: after ./configure --prefix=/usr,
my config.h ends with

#define HAVE_SYS_MMAN_H 1
#define HAVE_SYS_PARAM_H 1

#define HAV^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@

the ^@ being null chars, that go on for several pages.

I guess this is a bug with the configure script?

Any help?

This seems unlikely, given that it works fine on many fate boxes:

Is this a regression?
Please add at least some information about your environment.

Hopefully someone will be able to suggest a better solution than this, but  
there was at one time an avisynth filter that would let you put a  
Photoshop saved curve onto video; if you're on a platform where avisynth  
exists, you could do it that way.

I'm not sure there is a LUT filter available in ffmpeg, but I'm not sure  
there isn't either.

It's on Linux x86, kernel 3.4, gcc 4.5.2, with glibc 2.13; it has make
3.82, makedepend 1.0.3, binutils 2.22... Any other info needed?

I've attached an example of the default cineon dpx and the linear dpx.
When the linear dpx is converted to a mov it should look the same as the 
cineon dpx.

Thanks Carl

Sorry for the lack of action. I usually read every message on the

Message-ID: <CAJQ5m2MQZ5bZSzwGs7198HgQpbo2jxik7ANF-DZ2AP7pH94p3w@mail.gmail.com>

Hi all,

Can anybody tell me that how can I split a video file without re
transcoding it.

Yes there is a command:

ffmpeg -ss <time1> -i <input> -acodec copy -vcodec copy -t <time2> <output>

But the confusion I am having is, does above command doesnt at all do
transcoding hence consuming the CPU?

To record audio I use the following command:

      -ac 1 \
      -ar 22050 \

The strange thing is that most of the time I have a good recording,
but sometimes the audio is faint and with a lot of white noise. (And
because of Murphy, this happens when I record a long audio.) Anybody
an idea why this happens? And what to do about it?

Could it be that the 'white noise' problem hits you when the source is dolby or dts and there is no dolby/dts-decoder available in your ffmpeg version ? Just a guess.

As soon as FFv1.3 is considered "stable", this would make sense.
However, right now v1.3 is marked "experimental" - and therefore it  
would be dangerous to automatically enable the bitstream.

So, as far as I understand it, your "problem" is only temporarily -  
and will be gone as soon as FFv1.3 is officially released as stable.

Ooops! My bad:
I somehow overlooked that you were just encoding a >8bps file - and  
not accessing a feature that required "-level >1". Forget my above

Subject: [FFmpeg-user] Can FFmpeg create a separate transparent PNG track?
Message-ID: <CAN0LTaOV6MmwnNam3OgFjanwwHBEdrNPr2sFw4So9mQRNTYUgA@mail.gmail.com>

I know it's possible to embed a transparent watermark using video filters,
e.g. like this:

ffmpeg -i input.mp4 -vf "movie='logo.png' [logo]; [in][logo]
overlay=main_w-overlay_w-10:10 [out]" out.mp4

This creates a file with one video track, where the transparent logo is
correctly shown in the upper right corner.

However, is there a way to add a separate transparent track to the
container, which then could be toggled on / off individually?
The following creates two video streams, one for the overlay:

ffmpeg -loop_input -i input.mp4 -i logo.png -map 0 -map 1 output.mp4

But since the overlay is converted from PNG to an actual video bitstream,
it's not transparent anymore (plus, it has to have a width/height divisible
by 2, etc.).
Is it even theoretically possible to create a transparent stream like that?
If so, how would I go about doing so?

Best regards,
Werner Robitza

Message-ID: <CAL65Gdcvu08+5nEYHtk2EtfhansRW52zEYKF8xcHrpGk-gRTzw@mail.gmail.com>

Hi,

I'm grabbing video from a grayscale video camera using an EasyCap
DC-60 USB adapter and ffmpeg. The data is encoded into a stream of pnm
still frames. By default these are in the P6 format and hence are
24bit RGB. Since the input is grayscale I have tried using -pix_fmt
gray to convert it to 8bit grayscale (P5), but I can not get this to
work.

Any clues as to why this does not work?

Message-ID: <4FC4A305.4010604@revsec.se>

Hi,
I'm trying to compile ffmpeg to use with mediatomb 0.12.1 and
ffmpegthumbnail.

I have tried to configure it as both static and shared with

./configure --prefix=/usr --disable-doc --enable-gpl --enable-version3
--enable-nonfree --disable-network --enable-shared

The compilation of ffmpeg exits with a lot of warnings about libavcodec like

*    libavfilter/af_aformat.c:125:51: warning: 'avfilter_all_formats' is
deprecated (declared at libavfilter/avfilter.h:295)
*    libavcodec/rv10enc.c:67:5: warning: initialization from
incompatible pointer type
*    ffmpeg.c:2970:29: warning: 'icodec' may be used uninitialized in
this function

After that when I try to compile mediatomb and ffmpegthumbnail with
ffmpeg they exit with errors related to libavformat. For example

ffmpegthumbnailer:
libffmpegthumbnailer/moviedecoder.cpp:162:57: warning: 'int
avcodec_open(AVCodecContext*, AVCodec*)' is deprecated (declared at
/usr/include/libavcodec/avcodec.h:3380)
make[2]: *** [libffmpegthumbnailer_la-moviedecoder.lo] Error 1

mediatomb:
../src/metadata/ffmpeg_handler.cc:279:35: warning: 'void
av_close_input_file(AVFormatContext*)' is deprecated (declared at
/usr/include/libavformat/avformat.h:1533)
make[2]: *** [libmediatomb_a-ffmpeg_handler.o] Error 1


Is there anyone who has any ideas how to approach this?

Regards
Simon

Both png and qtrle can be put into an isom container and read by

Subject: [FFmpeg-user] frame accurate durations
Message-ID: <2A326DB2FB866B4C98676159D8A130016291C255@LNDWSMBX01.ad.mpc.local>

Hi there,

I'm trying to split up a quicktime to render over multiple machines for a later concatenation, and having trouble getting the sections to be the right length.

These are the command line inputs, splitting the quicktime into chunks of 9 frames (this is a test clip, the usual renders are longer)

/usr/local/bin/ffmpeg -i 'input.mov' -ss 0.0 -t 0.36 -vcodec v210 -y 'output[0-8].mov'
/usr/local/bin/ffmpeg -i 'input.mov' -ss 0.36 -t 0.36 -vcodec v210 -y 'output[9-17].mov'
/usr/local/bin/ffmpeg -i 'input.mov' -ss 0.72 -t 0.36 -vcodec v210 -y 'output[18-26].mov'
/usr/local/bin/ffmpeg -i 'input.mov' -ss 1.08 -t 0.36 -vcodec v210 -y 'output[27-35].mov'
etc

The start time is defined as: start_frame/framerate, so in this case 0/25, 9/25 18/25, etc... and the duration (t) is chunk_size/framerate, ie 9/25. (all calculations done as float).

The input clip here is h264, output uncompressed v210.

Some of the resulting sections are the right length, but some are one frame shorter, which produces jumps when concatenating them.

Below is the terminal output from one of the inaccurate length clips.

Is there a better way of being more accurate with the duration or is this a limitation inherent in ffmpeg?


Many thanks

Chris

Use pgm if you want gray output.

This can only be done this way if all frames are i-frames/keyframes. NON-All-Keyframe files you only can 'split' at 
a i-frame/keyframe and often they are not a 'regular' intervals.
Further your ffmpeg version is more than a year old.

Carl et al.

I have not seen any working example of the FFmpeg segmenter tool.
Does anyone out there have a link to one?

Thanks,
Fing.

Clement,

Thanks, I am aware of the documentation.
I was just  wondering if there was an example generating
the ".3m8u" list file and ".ts" segements compatible with Apple HLS
OR
".mp4" segments and ".mpd" list file compatible with MPEG-DASH.

As it looks now, I will have to do my own scripting to get the correct file
formats and video coding.

Better to ask first than re-invent the wheel :)

Fing.

I know, but I figured it would be obvious from the example that it does not
"simply" work that way since the transparent PNG is automatically encoded
with to an MPEG-4 or H.264 bitstream unless other options are supplied.

Both png and qtrle can be put into an isom container and read by

 Would you have an example command of how to achieve that?

You could decompress (-i input.mov), convert to v210 which is of course un-compressed and I-frame, then output to ffmpeg's pipe: pseudo-file, and pipe that to another ffmpeg, inputting from the pipe, then perform your -ss and -t, which by this point should be a stream of I-frames - meaning your timings should be properly honoured.

I'm not sure that's true,

Since he is re-encoding the stream here, he can use -ss option as an
output option. This way ffmpeg can cut on an arbitrary frame because
it will decode the whole stream prior to cutting. Since all frames are
decoded, it can stop on any.

The issue with this method is that each invocation of ffmpeg will need
to re-decode the whole stream up to the cut point, which can be slow
if you wish to cut far ahead in the file.

Yes, I would have thought that as this is a transcode, rather than a vcodec copy, especially to an i-frame codec, that ffmpeg would need to retain the full frame information in the buffer. Also, the source file has keyframes every 25 frames and the segments are only ever out by a frame. Out of 12 segments it's usually missing around 5 frames, which doesn't seem to tally with what it would be if it was a keyframe issue.

I'll try running this again with an i-frame source and see what happens.

Thanks for your responses

Chris

I do not think so. It is also the same source: a microphone. For
example: Monday I recorded something. The sound was faint, with a lot
of noise. I immediately made a new recording. (With the same
microphone. I removed it and put it back, but that should make no
difference, or should it?) That recording was correct again. So then
it should not be this problem I think.

the segmenter at the moment is  gpac which do segmenter the stream. and i dont know (understand) the syntax (order segment_duration segment_name segment_list) for segmenter with ffmpeg

Hi, sorry for the delay, been on a short vacation :D

Thank you for you answer. The internal codecs do not seem to reproduce the
same problem. However, I have to check with my client if using mpeg4
instead of h.264 is ok with them (you know how clients are sometimes).

Other than that, you think there might be some other workaround? Or that's
something I'd have to check with the libx guys.

One curious thing is that using libx with other containers (mp4, for
instance) doesn't seem to reproduce the same problem.

I've seen similar effects. For me it was caused by the audio codec adding a
small delay. If the delay is more than half a frame then QT adds the extra
white frame to the end.

As I understand it, from Googling and this mail list, some audio codecs
overlap audio frames, and add the audio from the overlapped parts together.
So, without adding a delay the first half of the first audio frame would be
at half level.

I haven't re-tested faac in a mov in the last year or so.

No if the source is the same, your microphone, it has to something else.
Your microphone is the same, your ffmpeg version is the same, your command line is the same. The difference is removing and reinserting your microphone.
Is it a 'real' microphone, connected with a 3.5' jack, or the microphone of a webcam connected with USB ?
If it's a 3.5' jack it looks like some alsa/pulse problem or it could be some USB/IRQ problem. Does the log tell something when you remove and reinsert the microphone ?

Subject: [FFmpeg-user] ffmpeg threads not deleted after closing streams,
	resulting in mem-leak
Message-ID: <CAMcjQ_9qOSk_1npEZUJMo1u=iDKQs8f290fmAqnCASFEnJwoMQ@mail.gmail.com>

Hi,

I am having a problem where every time I play a movie in the app I am
writing (using ffmpeg LGPL), after closing a file it seems like it is
leaking a lot of memory.

Recently I have mostly developed on Mac OS X 10.7 and every time I close a
video file and then open another one, it seems to leak quite a lot of
memory. The more threads I use, the more severe the problem is, if I set
codecContext->thread_count to 1 it is the least (but that doesn't give good
enough results for HD movies).

Also if I stop execution with the debugger, it seems every time after
closing a file, there are some "leftover threads" from ffmpeg (which I
assume might hold the memory that is leaking). In my current setup with a
1920x1080 HD file I am left with 5 threads and about 50 MB of leaked memory
every time I play a movie. (I didn't seem to have that issue before when I
used ffmpeg 0.9 and single thread)

So I am wondering if with recent changes there is something that I am not
doing correctly, or if this is really a known bug in ffmpeg?

My flow is (roughly) like this:
- avformat_open_input()
- then I pick the streams that I want to use, find a decoder
avcodec_find_decoder() and open it avcodec_open2
- I read the file with av_read_frame and put the packets into their
respective decoders, and av_free_packet them afterwards
- once I am finished I call avcodec_close for all the opened codec and
finally avformat_close_input

I make sure all the packets, and all the objects I created along the way
(swresampler, swscaler, various AVFrame objects etc) are deleted prior to
calling the close functions.

But is there something I need to do to ensure the threads that are created
inside ffmpeg are terminated and all the memory they allocated is removed?

thanks
Bjoern

It is working with WMP but crashes Powerpoint and Windows Media Services.

Version 0.9.2 is working. The converted file with  
99bb88c588ea9a46a06b966b9014394385ebe1c3 and above did not work within 
Powerpoint.

Please let me know how I can further help to identify the issue.

I have the  same issue since  i have pgradiong to kernel 3.4 on severalsmachines 
there is garbage at the end of config.h after doing ./configure 

in the script configure 
there a copy from a temporary config.h ( $TMPH) to config.h
the $TMPH is good , not the config.h

if you add a line cp $TMPH config.g the the configG is correct  !

clearly it's a kernel 3.4 issue.

As a feature request, it might be nice to easily "know" which codecs
support using multiple threads or not.

$ ffmpeg -codecs

lists all the codecs, so maybe possible to add it there somehow?

Does FFmpeg support this feature or does anyone know of a software suite 
that can?

Greetings:

I noticed that this works:

$ ffmpeg -i something -vcodec qtrle -o yo.mov

however this results in a file that plays back "without video" in
ffplay/vlc/mplayer:

$ ffmpeg -i something -vcodec qtrle -o yo.mov

Does this mean that the avi mixer should "reject" qtrle, or this is a

Given that both commands look similar, do not work and complete, 
uncut console output is missing, I don't think we can help you.

No, because you may choose a fourcc - for example RogP - that 
ffmpeg will happily write for your avi, but that will create 
more files that are unplayable with anything outside the 
FFmpeg / MPlayer universe, which we try to avoid.
Otoh, if you find an avi with qtrle in the wild, we will 
probably support it (and I agree with you, 
at least a warning would be fine).

Did you go to the projects' homepage, click on "Documentation", 
chose "FFmpeg Documentation" (since that is the tool you are 
using), and search for "segment"?
If yes, you missed this part:

Subject: [FFmpeg-user] Strict Experimental / 3GP not working with LGPL
	Compilation
Message-ID: <CALzb=BTxuXXOKagd_E9BHnZyguffLsgKeVntJm_4bqpFxgME2w@mail.gmail.com>

Dear All,

I've historically used a GPL compiled version of FFmpeg to convert to the
3GP format and it worked perfectly with the following command line:

ffmpeg.exe -i sample1.flv -vcodec mpeg4 -acodec aac -strict experimental
-ac 1 123.3gp

However, in the last few weeks I've moved to a LGPL compilation for
licensing reasons. The LGPL builds were produced by Zeraneo based on
ffmpeg-20120511-git-9eb99ab-win32-shared-lgpl.

However, now I cannot get the above command line to work and cannot convert
to the 3GP format.

I am passing '-strict experimental' and the FFmpeg DLL returns a code which
suggests it has successfully accepted the parameter (it?s in opt_default
function). But later, in the code it fails with the same error ? 'code is
experimental'.

I've also tried using the following command line but this also fails:

ffmpeg.exe -i sample1.flv -vcodec mpeg4 -acodec libvo-aacenc -ac 1 123.3gp

Can anyone help? Thanks.

Tim

I don't know if it's a kernel issue, however I tried some things, and
here are my findings:

instead of cp_if_changed $TMPH config.h, I put

cp $TMPH here
cp $TMPH config.h

and both 'here' and 'config.h' were corrupted.

However, putting

cp $TMPH /tmp/here
cp $TMPH config.h

gave me a correct config.h... Really, really strange ! But a least I
can try to compile and install ffmpeg :^)

Thanks for the hint!

The "-sameq" option is not recommended in this case. It does not mean
"same quality" as the documentation used to imply. It's a complicated
option and 99% of the time the best use of it is to not use it at all.
When using the mpeg4 encoder, as you are, use "-qscale" instead with a
value between 2 and 5. A lower value is higher quality.

This is not from FFmpeg. We recommend that you use ffmpeg from FFmpeg
which can be acquired from Jon Severinsson's FFmpeg PPA at:

https://launchpad.net/~jon-severinsson/+archive/ffmpeg

...or easily compiled by following the instructions at:

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

Your input ppm files are being read at "-r 25". This is the default
unless you declare your own -r as an input option (before -i). Try
moving "-r 10" as an input option (the output will inherit this rate).
Otherwise ffmpeg will drop, as in your case, or duplicate frames if
there is a difference between the input and output -r.

Overlay as Carl mentioned:
ffmpeg -i right.mp4 -filter:v "[in]setpts=PTS-STARTPTS,pad=iw*2:ih:iw:0,[T1]overlay=0:0[out];movie=left.mp4,setpts=PTS-STARTPTS[T1]" output

Ok that makes sense.  Players aren't "used" to seeing qtrle in avi's
so don't accomodate for them, which is ok for now (and agree about the
warning).
As a note, not even ffmpeg/mplayer plays these avi's back right, but
if they're mov's they do splendidly.
And no I haven't run into any "in the wild" except the ones I
accidentally created.
Thanks!

These are different:
ljpeg [1], lossless jpeg, is an addition to the jpeg standard.
jpeg2000 [2] was developed much later and may be either lossy or lossless.

Just to make sure this is not unclear:
There is ljpeg and lossless jpeg (two different things), 
and both are not jpeg2k related.

FFmpeg supports both ljpeg, lossless jpeg and jpeg2000, 
the jpeg2000 implementation is incomplete, help is welcome!

Complete, uncut console output missing.
(Both the mpeg4 and the native aac encoder are LGPL.)

Hi Lou,

Many thanks for your elaborate comments! I removed the ffmpeg version I
installed from the Ubuntu repositories along with the linked libraries and

I keep getting this error message for every combination of options I use. I
also checked in the list that the solution of " #0:0 - maybe incorrect
parameters such as bit_rate, rate, width or height" is to remove all x264
binaries, redownload the latest x264 and recompile ffmpeg. Yet those
version of x264 and ffmpeg I installed are the latest. The only thing I 've
changed in the recommended installation procedure is that instead of saving
and installing the programs/libraries in my home directory, I installed
them in ~/Programs subdirectory. I don't know if this really matters. Do
you have any other idea what may be wrong???

Thanks in advance.

You're applying "-qscale 5" as in input option (before -i), and since
it is an output only option it is being ignored. It should be used as
an output option (after -i WT_Hbonds.%05d.ppm).

However, the default behavior has changed now that you are using recent
ffmpeg. It now automatically chooses the libx264 encoder (you can see
this mentioned in the console output), if available, instead of the
mpeg4 encoder for mp4 output. The -qscale option should not be used with
libx264. You can use -crf instead. Default value is 23. A lower value
is a higher quality. A sane range is around 18-28. Generally you use
the highest value that still gives you an acceptable quality.

> [libx264 @ 0x20f05e0] height not divisible by 2 (1280x745)

libx264 requires your width and height to be divisible by 2. Either
modify the height with the crop, pad, or scale filters:

ffmpeg -r 50 -i WT_Hbonds.%05d.ppm -vf crop=iw:ih-1 crop.mp4
ffmpeg -r 50 -i WT_Hbonds.%05d.ppm -vf pad=iw:ih+1 pad.mp4
ffmpeg -r 50 -i WT_Hbonds.%05d.ppm -vf scale="iw:trunc(ow/a/2)*2"
scale.mp4

Or go back to the mpeg4 encoder which is less picky (but less
efficient):

ffmpeg -r 50 -i WT_Hbonds.%05d.ppm -c:v mpeg4 -qscale 5 test.mp4

This odd height was the issue here as mentioned earlier.

Unnecessary since you just did that and have the most recent ffmpeg and
x264.

Using ~/Programs instead of ~/ should be just fine.

HI Carl,

Thank you for the reply. I'm sorry I didn't quite understand your comment
"Complete, uncut console output missing." Can you explain a little more.
Does the command line I mentioned work for you?

Thanks.

You posted a command line and asked for help.
On this mailing list, you are supposed to never simply post 
a command line (if you need help), but always post your 
command line together with the complete, uncut console output.

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

Subject: [FFmpeg-user] Possible ffmpeg regression in encoding interlaced
	h264 video
Message-ID: <4FC71DC2.5070207@glidos.net>

I use this command to archive TV recordings:

/usr/bin/ffmpeg -f ac3 -i <audio-in> -f rawvideo -top 1 -pix_fmt yuv420p 
-s 1440x1088 -r 25 -i <video-in> -threads 2 -vf crop=1440:1080:0:0 
-vcodec libx264 -preset medium -profile high -flags +ilme+ildct -crf 
20.0 -aspect 16:9 -acodec copy -ar 48000 -f mp4 <encoded-file-out>.mp4

It used to work perfectly, giving a smoothly playing 50Hz interlaced
file. Something has changed recently, and now it still mostly works,
but the file produced is somehow marked as bottom-field-first,
rather than top-field-first. The system I use to playback has a
setting for reversing the interlace, so I can play these back and
see that in every other way the encoding is still correct.

Anyone know of changes that may have broken this? Should I be looking
at x264 rather than ffmpeg fort he cause, perhaps?

Cheers,
	Paul.

Message-ID: <CAP1T9tYMiB8KRDR_XmMVWEXwtOe81xXztYr5EJcFvaJs77b2xA@mail.gmail.com>

Hi,

  I'm using ffplay to play a mpeg ts stream over tcp. After started, the
server will keep sending ts packet to ffplay, but ffplay wont start playing
it until I stop the tcp stream at server side by press Ctrl+C.
  Seems that the ffplay keep reading the stream, until it reach the eof of
the stream, the play started.
  Is there any way to make it play immediately while receiving packets?
such as buffer 3 frames and then play.

My command:

ffplay -f mpegts -ast 1 -vst 0 -ar 48000 tcp://192.168.244.226:5000

Please try with current git master and

Thanks for this, not really what I'm looking for -- this seems to make lots of segments of one file on one instance of ffmpeg. What I'm trying to do is make one segment on one instance of ffmpeg, but use many instances of ffmpeg running in parallel to get very quick transcoding (and then concatenate the segments later).

But to do this I need the output from ffmpeg to be frame accurate and consistent with the -ss and -t tags, which doesn't seem to be the case.

Oh well.

Thanks for all your help everyone.

If you really want to do this for performance reasons, I don't 
think it is the correct way to go, better try -threads.

I repeat it's an issue for 3.4 kernel which semms a little naughty

Subject: [FFmpeg-user] FFmpeg configure error :
Message-ID: <CAN0mk4a1huzAZcvp9P3GHENOMG0a+qbEcvbnjaSAFd-A6i=+_A@mail.gmail.com>

Following the guide
https://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide, I m trying to
compile ffmeg from GIT with VP8 support on Ubuntu Server Edition (last
release).

The command :

./configure --enable-gpl --enable-libfaac --enable-libmp3lame
--enable-libopencore-amrnb \
  --enable-libopencore-amrwb --enable-libtheora --enable-libvorbis
--enable-libvpx \
  --enable-libx264 --enable-nonfree --enable-version3

gives me the following error :

ERROR: libvpx decoder version must be >=0.9.1
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.

Could you help me ?

Regards,

Vincent

Subject: [FFmpeg-user] Transcode 5.1 Flac to 5.1 LPCM in ffmpeg
Message-ID: <op.we6zlvvc5nam2o@weboffice>

Hello,

What's the right command to transcode 5.1 Flac to 5.1 LPCM audio in  
ffmpeg? I need to stream it to a network BD player? Original Flac is FLAC,  
5.1 channels, 0:40:38, 16 bits, 2502kbps, 44.1kHz , and LPCM should be the  
same. Will it play on DLNA-compliant BD player? What should be file  
extension for 5.1 LPCM: for example lpcm, l16, or what?

How can I pack it to MKV container that is supported by the player?

Also, how to transcode 5.1 Flac to 5.1 Dolby TrueHD packed into MKV or MP4  
container?

What PC Soft Media Player can play LPCM format? I need to verify on PC  
that the resulting file is playable in principle, no header errors. How to  
do that?

Thanks for clarification!

Subject: [FFmpeg-user] Compiling FFmpeg for 32 bits (i386) on Mac OS X
Message-ID: <CAJ29FNbT1XCAOmAoa8nGGDLKJCedu8dDV_ikgJAN6ruiZVoWwA@mail.gmail.com>

I'm on Mac OS X 10.6, x64, using gcc4.2, and I'm trying to build
FFmpeg so that it can be used on 32 and 64 bit Macs (so I'm trying to
do a i386 build). I've tried several configurations, but so far they
all die on libswscale/x86/rgb2rgb_template.c. I've configured with:

./configure --enable-shared --disable-static --arch=x86_32
--extra-cflags="-arch i386" --extra-ldflags="-arch i386"
--extra-cxxflags="-arch i386" --target-os=darwin
--enable-cross-compile

(also tried ./configure --enable-shared --disable-static --arch=x86_32
--extra-cflags="-arch i386 -fomit-frame-pointer"
--extra-ldflags="-arch i386" --extra-cxxflags="-arch i386
-fomit-frame-pointer" --target-os=darwin --enable-cross-compile)

Which works fine, but then when I make I get the error:

CC	libswscale/x86/rgb2rgb.o
libswscale/x86/rgb2rgb_template.c: In function ?rgb15tobgr24_MMX?:
libswscale/x86/rgb2rgb_template.c:814: error: can't find a register in
class ?GENERAL_REGS? while reloading ?asm?
libswscale/x86/rgb2rgb_template.c:811: error: ?asm? operand has
impossible constraints

impossible constraints
libswscale/x86/rgb2rgb_template.c:879: error: ?asm? operand has

Does anyone have any idea of how to correctly build 32 bit libs for Macs?

Thanks,

Michael
