Subject: [FFmpeg-user] Radiostream rip, w/o recoding, irregularly fails
Message-ID: <c4e93c40-d584-49be-9e42-7b962325cfc8@email.android.com>

Hi listpeople,

I am trying to swich my private radio recorder from using mplayer to ffmpeg as some tests have resulted in more usable files. Anyway, after having it running for a few weeks now I am facing an issue I have not yet found a solution. As extended internet searches did not help me either I am now seeking help here.

The problem: irregularly I get only a few k sized files from one record job or it stops too early. At another time the same job completes as expected. I have searched for a way to increase the buffer cache but did not find it inside the man.

Is audio grabbing not yet completely mature?

This is the cmd I am using:

ffmpeg -i $streamurl -vn -acodec  copy -t 01:01:00 filename

Any help appreciated. What cmd line are you folks using? I do NOT want to recode because I do not want to  reduce the audio quality even further, just dumpstream.

can you provide any examples of the complete command line output of when it ?fails? and when is successful?

can i ask what the source stream is? server type/audio codec?

you might try

ffmpeg -ss 0 -i infile -t 01:01:00.000 -c copy outfile

Message-ID: <1420932.BDBbWgqoam@reik.site>

Hi, 

I am searching a way to insert private SEI messages before each picture when encoding with x264. As far as i see from the libx264.c code, it is not supported up to now.
Am i correct ?

If yes, i am willing to push patch to support this, but do you have a preferred way to do this (ie thru medata field of AVFrame ? thru sidedata of AVFrame ? ...)

Thanks for your hints, 

Regards, SF

(Actual command line and complete, uncut console output 
missing.)
mplayer -dumpstream is the recommended way of recording 
streams, maybe -re helps.

This sounds to me as if setting the H264 level through 
FFmpeg does not work.
Is that correct?
How can I reproduce this?

Can you record the stream (with wget) to provide an

The reference decoder only decodes the first three

(reception or encoding errors).

"-f h264" is unneeded.

OK its working!!!!!, but i need some help on a little
 problem with my code. snippet below


....
??? /* initialize packet, set data to NULL, let the demuxer fill it */
??? av_init_packet(&myframe->pkt);
??? inputSource->pkt.data = NULL;
??? inputSource->pkt.size = 0;

??? /* read frames from the file */
??? while (!inputSource->quit && !stop_all_tasks && av_read_frame(inputSource->fmt_ctx, &inputSource->pkt) >= 0) {
??????? AVPacket orig_pkt = inputSource->pkt;
??????? do {
??????????? ret = decode_packet(&got_frame, 0, inputSource);
??????????? if (ret < 0)
??????????????? break;
??????????? inputSource->pkt.data += ret;
??????????? inputSource->pkt.size -= ret;
??????? } while (inputSource->pkt.size > 0);
??????? av_free_packet(&orig_pkt);
??? }


I then added a callback but this never seems to be called!!!

static int interrupt_cb(void *ctx)
{
??? inputMosaic *inputSource = ctx;

??? printf( "."); fflush( stdout);
??? if (inputSource->quit || stop_all_tasks)
??????? return 1;

??? return 0;
} 


and in the inputThread

??? inputSource->fmt_ctx->interrupt_callback.callback = interrupt_cb;
??? inputSource->fmt_ctx->interrupt_callback.opaque = myframe;


Now as this is running in a thread it works well as long as THERE IS data. if no data then this loop just stays here and
 I cannot kill it when I need to switch the input stream or even close down.


Anyone help on this.

It's a little more subtle than that; I'll try to explain.

1. When using presets, in my testing (lib)x246 does not use '--level m.n'/'
-x264opts level=m.n' to govern refs. In this scenario refs are governed by
preset alone in accordance with the preset settings listed by  x264
--fullhelp. (Although besides the point, (lib)x264 is actually prepared to
write specified level metadata that differs from the level encoded to, at
least when the latter is lower.)

2. The ffmpeg option '-level x.y' does set refs correctly, even when using
libx264 presets.

3. However, '-level x.y' is undocumented, while the '-x264opts' pass-through
mechanism is.

https://trac.ffmpeg.org/ticket/3947#ticket addresses 1, 2 and 3.

None of the above presents a problem when the target device manufacturer
specifies conservative individual maxima for _all_ parameters that govern
encoding level (e.g. frame size, frame rate, bitrate etc.), as well as for
refs.

a. Still, adhering to such conservative maxima might lead to sub-optimal
encodes. E.g., when using less than the specified maximum frame size, a
higher bitrate and/or refs value could have been used within the limits of
the specified level.
 
b. In all other cases - even when maximum level is specified - it is up to
the user to determine whether desired frame size, frame rate, bitrate etc.
will result in a conformant output level, at least. (When not using ffmpeg
and '-level x.y' the user will also need to determine the corresponding
maximum refs value for the particular combination of parameters.)

c. When the user is not concerned with conforming to a _specific_ level but
just conformance to whatever output level the encoder decides on, in most
cases 1. above will ensure that output is non-level-conformant. This is
especially true when using preset veryslow, which always sets refs to 16.
This can be overcome by specifying either '-level x.y' or refs directly, but
in either case the user needs to know the resulting output level in advance.

h264level and ffx264 address a, b and c.

Hello folks, I recently created a screencast tutorial regarding the remastering of a neglected audio track from a multimedia file with Audacity and remuxing and reencoding the audio export back to a multimedia file(video and audio) with FFmpeg.

I hope you enjoy it.

When a file has more audio tracks, it is handy to name them and at least  
VLC can show their names - or titles, I am not sure about the terminology  
- in menu under Audio>Audio Track. How do I set the names using ffmpeg? I

Set the right metadata.  "name"?  "title"?  "title" probably.  Look at
one that already does the Right Thing (TM)

Do you happen to have a (short) sample which shows your desired

Unfortunately, no, the file in question has 7,2 GB. I attach a screenshot  
of what I mean.

Can you post what gets printed when you run:
ffmpeg -i BIGFILE

Okay, now we know how to produce a file in which VLC recognizes the
names of audio streams:
$ HandBrakeCLI [...] --aname "Name of audio track 1,Name of audio track 2"

Only HandBrake and VLC seem to agree on this info, neither ffprobe
(with any -show_* option) or mediainfo show this track name (in my
experiments with an MP4 container).

Too tired to try to disassemble the MP4, and my AtomicParsley is
segfaulting. Your turn. :)

Good night,
Moritz

Hm, if it is something proprietary to VLC and Handbrake, I can probably  
let it be...

Subject: [FFmpeg-user] Problems saving rtsp stream directly as mpegts
Message-ID: <CAK-U3Hd6621mOwNN2fNUU9pfU6Yqm5-h6zZsV7XNBxQ3HjXQ1g@mail.gmail.com>

Hi,

I am try to capture an rtsp stream with h264 from an IP camera directly
into an mpegts file.

ffmpeg -i rtsp://10.9.9.3:554/axis-media/media.amp -c copy -f mpegts out.ts

This seems to work fine, but the output file is not recognised by
ffmpeg/ffprobe.

ffmpeg -i out.ts

[h264 @ 0x7fa96501d200] decode_slice_header error
[h264 @ 0x7fa96501d200] no frame!
[h264 @ 0x7fa96501d200] non-existing PPS 0 referenced

(Video: h264 ([27][0][0][0] / 0x001B)): unspecified size
Consider increasing the value for the 'analyzeduration' and 'probesize'
options
out.ts: Operation not permitted

Any idea why this is?

If I do it in two steps, first saving the stream as a .mp4, it converts to
mpegts fine with:

ffmpeg -i out.mp4 -c copy -bsf h264_mp4toannexb out.ts

Is it possible to do this in one step without the intermediary file?

Thanks,
-Jonathan.

Complete, uncut console output missing.
(I would have expected above command to return an 
error message and I would like to know why there 
is no such message.)

What happens if you add the bitstreamfilter to the 
first command?

If somebody could now either upload a small sample or 
provide an actual command line, we could try to 
implement the missing feature...

I experience the same accelerated playback, both with elementary
streams demuxed by ffmpeg as well as x264 itself.

Something else I noticed in the output file in both cases is that its
frame rate gets set to variable, although that patently wasn't the
case for input files I tested with, and there were no command line
options influencing frame rate.

In the case of x264, the --fps <framerate> option seems to solve the
problem, with <framerate> set to that of the input file. I haven't
tested with ffmpeg.

Sorry, I was quite tired and didn't know what I was thinking.

I'm attaching an artificially created file, as it's smaller than most
log files. ;-)

Created as such:
$ ffmpeg -y -f lavfi -i testsrc -f lavfi -i sine=f=880 -f lavfi -i sine=f=1000 -map 0 -map 1 -map 2 -t 0.5 in.mkv
$ HandBrakeCLI -i in.mkv -o out.mp4 --audio 1,2 --aname "880 Hz sine wave,1 kHz sine wave"

Sorry, my HandBrake is really old and has problems with the video, but
the point is moot: VLC shows the two audio tracks of out.mp4 exactly as
I tagged them with the HandBrake command line.

BTW, using ffmpeg, I notice that when I use
'-metadata:s:a:0 name="880 sine"', the file creation process shows me:
    Stream #0:1: Audio: aac (libfdk_aac) ([64][0][0][0] / 0x0040), 44100 Hz, mono, s16, 96 kb/s (default)
    Metadata:
      name            : 880 sine
      encoder         : Lavc56.10.100 libfdk_aac
yet ffprobe fails to display the "name" metadata in the resulting file.
This field - if it is a metadata field - does not seem to be supported
by the MP4 muxer, and again ffmpeg is "lying" ;-) about its metadata
creation - similar to the thread I started recently.

P.S.: I can actually see the "tags" in a hexdump of the HandBrake
created file:

I do not know, though, whether "name" is a header such as "stco" or

Subject: [FFmpeg-user] gas-preprocessor.pl unknown arch: 'ppc'
Message-ID: <54576040.1020201@gmail.com>

Hi,

I am trying to (re)build recent ffmpeg master 
(63e62cfbe23de8b362d94f783668620a2cd2b571) on OSX 10.5 ppc.  I have 
installed latest (2014-08-12) gas-preprocessor.pl from 
http://git.libav.org/?p=gas-preprocessor.git

When configuring the build it still complains and asks to install/update 
gas-preprocessor.  I am not sure whether this is a gas-preprocessor 
problem, or an ffmpeg build configuration problem. This used to work.  I 
don't know when it broke because configuring without gas-preprocessor is 
non-fatal, so it may have been broken for months and I haven't noticed.

One thing I've noticed is that -arch ppc doesn't work, but -arch powerpc 
does:

$ gas-preprocessor.pl -arch ppc -as-type apple-gas -- gcc -v
unknown arch: 'ppc'

$ gas-preprocessor.pl -arch powerpc -as-type apple-gas -- gcc -v

So apparently we're looking as MPEG4/MOV containers here. That's what
Tom?? was using as well, and where I managed to reproduce.

Using AtomicParsley, I managed to "see" that the tag in use is an atom
trak.udta.name:

     Atom trak @ 8193 of size: 560, ends @ 8753
         Atom tkhd @ 8201 of size: 92, ends @ 8293
         Atom mdia @ 8293 of size: 428, ends @ 8721
             [...]
         Atom udta @ 8721 of size: 32, ends @ 8753
             Atom name @ 8729 of size: 24, ends @ 8753

The atom is described here:
https://developer.apple.com/library/mac/documentation/QuickTime/QTFF/QTFFChap2/qtff2.html#//apple_ref/doc/uid/TP40000939-CH204-BBCCFFGD

I have found a mention that HandBrake and subler use this atom:
https://github.com/pjan/osx-dotfiles/blob/55d452fae4037a019c85a6095a5b3a0bd11e3d15/.dotfiles/.encode-handheld.pl#L2907

I couldn't figure how to add arbitrary atoms with AtomicParsley, only
how to delete them. I do see ffmpeg has a function named
mov_write_track_udta_tag(), called from mov_write_trak_tag(), called
from mov_write_moov_tag(), but I don't know if it gets used and whether
it does the "right thing" from VLC's point of view, and how to get it
to write the "right thing".

Getting closer,
Moritz

P.S.: Interesting, because it follows a question I never dared to ask:
      Where does my PVR/STB get the names of its audio tracks from?
      (Albeit MPEG-TS.)

I looked at ffmpeg's source, and figured out that it uses the above
functions to write the trak.udta.name atom for its metadata "title":

$ ffmpeg -y -f lavfi -i testsrc -f lavfi -i sine=f=880 -f lavfi -i sine=f=1000 -map 0 -map 1 -map 2 -t 0.5 -metadata:s:a:0 title="880 sine" -metadata:s:a:1 title="1000 sine" out_ffmpeg.mp4

AtomicParsley now sees reports the tag, just like it did for
HandBrake's file:

$ AtomicParsley out_ffmpeg.mp4 -t 1
[...]
User data; level: track=2; atom "name" : 880 sine
User data; level: track=3; atom "name" : 1000 sine

So ffmpeg is basically doing the right thing with "title".
Unfortunately, VLC seems picky about this, and still doesn't display
it. This may or may not have to do with the differing major_brand,
compatible_brands, or the structure of the MOOV atoms. *shrug*

At this point, we'd probably need to look at VLC's source code to
figure this out. :-P There is some udta parsing in VLC's
modules/demux/mp4/mp4.c, in function MP4_TrackCreate(). It doesn't look
picky, but what do I know.

This happens on line 66 of gas-preprocessor.pl -- it checks the 
$comments dictionary for 'ppc', doesn't find it and gives up.  I've 
worked around the problem locally by adding 'ppc' => '#' to %comments on 
line 17.

Subject: [FFmpeg-user] How can I convert mpeg2 5.1 audio to ac3?
Message-ID: <trinity-e3ccc0bf-dbb1-4a9c-bb17-8bd8787cf7ef-1415092191194@3capp-mailcom-lxa13>

I have some .ts (transport stream) files that contain video and 5.1 audio but XBMC will only play them in stereo. It appears that the only type of file that XBMC will play in full 5.1 is an ac3 file, so my thought was to try converting the files using ffmpeg.

My original approach was to use:

ffmpeg -i "originalfile.ts" -c:v copy -c:a ac3 "new.ts"

This did create an ac3 file but with only two channels. After reading a bit more, I tried adding the -ac 6 switch, so it became:

ffmpeg -i "originalfile.ts" -c:v copy -c:a ac3 -ac 6 "new.ts"

This created a file that XBMC thinks is a Dolby 5.1 file (according to the on-screen display) but in fact the only audio present is on the stereo channels.

The source is definitely in MPEG-TS and it contains 5.1 information, although I'm confused as to how. One of the files is actually a speaker test video and if played in a different program (such as MythTV) it plays the "Left", "Right" and "Center" channels from those speakers, but the "Left Surround" and "Right Surround" audio comes from both the front and rear speakers of the specified channel, with a bit more emphasis on the rear. If played in XBMC it plays from the front speakers only. Yet if I attempt to display the properties in a program like iMediaHUD it only shows two stereo tracks that look like this:

I have no idea how they are encoding the 5.1 but I can assure you it's there, and all I want to do is use ffmpeg to convert it and similar files to ac3 so XBMC will play them in 5.1.  Can anyone tell me what I am doing wrong?

Complete, uncut console output missing, I don't remember 
a question where mediainfo output was useful.

How do you know that your input file contains surround 
information? Is it because you have a dolby certified 
receiver that allows you to play two-channel audio with 
surround effects? In this case, do not reencode audio: 
FFmpeg has a Dolby PLII encoder (resampler) but no 
decoder, just convince xbmc to not mess with audio and 
allow your receiver to do what is necessary.
(Analog input may be required iirc.)

Sorry, different forums want to see different types of information, and in some they give you a hard time if you post a message that is too long.  I will post console output at the bottom of this message.

First off, please don't use too much technical jargon with me, I really don't understand it.  My receiver has the Dolby digital logo (and DTS and THX logos) on it.  But the reason I know the file contains surround information is very simple:  One of the files is an audio test file where someone says "Left, Right, Center, (low hum for subwoofer), Left surround, Right surround" and if I play that file in MythTV it plays with all the sounds coming from the correct speakers.  If I play the same file in XBMC only the front speakers are used.

Any suggestions on how to actually do that?  I have tried every setting that looks even remotely related.

Since I am new to the list I should probably state that I am not a developer or even a very technically-inclined user.  When I posted my message I was hoping maybe it was just some setting or switch I was not using in ffmpeg that I should be using, and that maybe some kind person could tell me what I am doing wrong.  But if you bury me in technical jargon I'm not going to understand what you are telling me so PLEASE try to keep it simple.

Here is what I think you mean by "console output".  And before you try to tell me there is no 5.1 in this file, this is the channel test recording I mentioned above and I can assure you that it does play in 5.1, with the channel identifications coming from the correct speakers, if played using MythTV.  So I have no idea why ffmpeg doesn't seem to notice the 5.1 any more than a mediainfo type program.  This is a mystery to me!

I should note that ffmpeg always complains about invalid frames or data at the beginning and end of these recordings, I do not know why but suspect it's because the recordings start and end based on time of day, and simply copy the transport stream to the hard drive without making any attempt to start or stop the recording on a frame boundary.  But, that is just a wild guess on my part.

How is your computer connected to your receiver?
I can choose here between analog, hdmi and 
TOSLINK (optical). If I use hdmi or the optical 
input, my receiver allows me to switch the 
"listen mode": As suspected, the audio uses 
Dolby PLII to encode surround sound via stereo 
channels. If I select "PLII" on my receiver, I 
hear the surround sound (with failures because 
the algorithm cannot be perfect).
If I use the analog input, I have to force the 
receiver to "two-channel" input to make it 
detect PLII: If I set it to 6-cable input 
(which is what I normally use), I cannot choose 
PLII.

As said, FFmpeg does not support PLII decoding 
(only encoding). Are you sure MythTV contains 
an internal implementation and not does not use 
your receiver's Dolby decoder?

Just to make things less confusing: Above has 
nothing to do with "mpeg2": You can use any 
audio codec that supports two channels and 
use it to store PLII-encoded surround sound.

There is also "MPEG-2 5.1" or "MPEG-2 
Multichannel". This is very rare and FFmpeg 
cannot detect it (nor decode it). I don't 
think your file can use both Dolby PLII and 
MPEG-2 Multichannel at the same time.

Wikipedia articles for Dolby PLII, toslink and 
MPEG-2 Multichannel exist.

Well that is interesting.  My computer is connected to my receiver via a S/PDIF (Toslink optical) cable but I know someone else who has encountered the same issue and he is using a HDMI connection, the difference being that I don't think he ever hears audio from his rear speakers when playing in XBMC (but he does in Myth, same as I do).

I know nothing about how MythTV handles audio so the short answer to that is "no".

That would explain everything, except why Myth can play this audio and XBMC can't (well actually it does, but it does a poor job of it - see below).

Do you know of any utility that can tell me if any of these lesser-known methods are being used?

> Wikipedia articles for Dolby PLII, toslink and
> MPEG-2 Multichannel exist.

Thank you.  I'm aware of Toslink but will look up the other two.

It turns out that the reason I thought XBMC was not playing anything from the rear speakers is because I did not have my ear right up next to them.  When I play the test video in XBMC, what actually happens is this:

Left, Right, Center, and the low frequency hum all play from the correct speakers and NOT from any other speakers.
Left Surround plays at significantly reduced volume from BOTH the left and right rear speakers, at normal volume from the left front speaker, and at normal volume but with breakups from the right front speaker!
Right Surround plays at significantly reduced volume from BOTH the right and left rear speakers, at normal volume from the right front speaker, and at normal volume but with breakups from the left front speaker!

This happens whether I play the original .TS file or the file that I attempted to convert using ffmpeg - it sounds exactly the same; I just never heard the rear speaker audio because the front is so much louder.

But as noted, if I play it in MythTV then all the audio comes from the correct spearlers - which is to say, Left, Right, Center, and the low frequency hum all play from the correct speakers and NOT from any other speakers.  The left and right surrounds both play from the speakers on their respective sides, but louder from the rear speakers than the front, and not on the opposite side's speakers as they do in XBMC.

>From what you are telling me, I'm guessing that ffmpeg cannot decode this signal and break it out to individual channels which can then be properly re-encoded as six channel ac3, but instead can only pass it through.  Is there a reason ffmpeg cannot do this or is it simply that no one has figured out a way to do it (yet)?  

In any case I thank you for the explanation - you are the first person that hasn't in effect tried to tell me I'm crazy for hearing 5.1 audio in this thing when I play it in MythTV.  I will read those Wikipedia pages you mentioned.

You mean you don't hear the "S" in "Surround" coming 
(to some degree) from the front speaker while the 
rest of the word is clearly coming from the rear 
speaker? I may have a cheap receiver...

Don't worry about MPEG-2 Multichannel, your sample 
is certainly Dolby PLII.
If you are interested, ticket #1258 contains source 
code.

What does your receiver show when you play with 
MythTV, what does it show for XBMC?
Maybe one is "Dolby Digital" (which is unrelated 
to PLII) and one doesn't show it / shows PLII?

Do you have a switch to change between "Stereo" 
and "PLII": My receiver has such a switch and 
it helps if I reencode the PLII stream to Dolby 
Digital with FFmepg:
$ ffmpeg -i input -ab 640k out.ac3
I can still here the surround via S/PDIF if I 
tell my receiver that this is PLII.

In MythTV, the surround sound comes from both the front and rear speakers for the specified side, but the volume is higher in the rear channels (might just be the way I have my speakers balanced).  Whereas in XBMC, a much lower volume is heard from the rear speakers and the channels aren't properly separated.

Thanks.  Is there a particular tool you used to determine that?  Mediainfo doesn't seem to know anything about it.

Unfortunately I would not know what to do with that, but thanks anyway.

Using MPlayer (and setting my receiver to PLII) I can 
clearly hear the sound as surround sound, but the "S" 
of "Surround" comes from the front instead of the rear 
speaker.
This doesn't change if I reencode the audio and send 
it directly to the receiver.
My assumption was that this simply shows the deficits 
of the PLII system.

Unfortunately, you can get neither support for XBMC 
nor MythTV here (the relevant question to them is 
probably: Are you reencoding my MPEG-2 two-channel 
audio to AC3 instead of sending it as PCM to give 
the receiver a better chance to know what to do?), 
I will hopefully open a ticket for PLII decoding, 
I have no idea how difficult / trivial this is 
given that we support encoding...

Iirc (and I think Wikipedia also explains this), there 
are a few very old DVDs that use MPEG-2 Multichannel, 
I severely doubt that it was formalized for DVB.
You can check the bitrate to be sure: I would expect 
that 256k are not enough for Multichannel.

And as explained, Mediainfo output is rarely relevant 
on this mailing list.

I have never heard of "PLII" prior to this thread.  MythTV tells me nothing about the audio, it simply reports it as 1080 and that's all, unless there is some hidden display option I don't know about.  XBMC reports it as "1080" "MPEG-2" "2.0" "MP3" "1.78"

No.

At least on my system, XBMC won't even acknowledge the presence of a file with a .ac3 extension.  If I change it to .mp4 then XBMC will play it but in exactly the same way it plays the .ts file - there is no discernable difference.

My receiver has options for THX, Dolby/DTS Surround, Stereo, and Direct.  Stereo and Direct play with no audio at all from the back channels, while THX and Dolby both play the file the same way I have described previously.  I usually leave it set on THX.

Thank you. That is all I can hope for. Given my lack of technical understanding I suspect I have taken this as far as I can go for the moment.

It would be really great if ffmpeg could detect these channels and reencode them to a more standard (if that is the way to put it) ac3 format. XBMC WILL play Dolby encoded files correctly if the channels are all present and not encoded in some weird format, in fact it is very good at that. Also, it actually indicates that such files are 5.1 rather than 2.0. The problem is that although I have been able to get ffmpeg to create a 5.1 channel ac3 .ts file (using the -ac 6 option, as mentioned in my original post), it does not seem to be decoding the channels from the original file correctly and therefore is not placing them into the output file correctly. So basically I would get like to get the channels extracted from this weird PLII format and into conventional ac3, if that makes any sense (I apologize if I am not stating this correctly but hopefully you understand what I mean). If there is any way you can accomplish that, that would be great!

    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^

I know (expected) that MythTV and XBMC do not show 
PLII. My receiver has a display and when digital 
audio (as via S/PDIF) starts, it shows something 
on this display.
While playing, I can switch the "Input mode" to 
change between "Stereo" and "PLII".

> My receiver has options for THX, Dolby/DTS 
> Surround, Stereo, and Direct.  

PLII is (the successor of) Dolby Surround afaict.
Since Dolby Surround and DTS Surround are two 
completely different things afaik, I am 
surprised that this is the same option...

I would be surprised if the file is THX but I 
don't know much about it, my receiver does not 
support it (too cheap).
(From a very quick look, THX is unrelated: 
"A common error is that THX is similar to 
Dolby Surround.")

Hi all,
I?m having trouble getting sdl output of ffmpeg to work reliably on my Mac. I want to do an encode and display the video simultaneously. I have been doing that by piping ffmpeg to ffplay but would like to drop the ffplay, since if I control-C the process then ffplay quits and the ffmpeg encode doesn?t end properly (no moov atom, etc). So I?m trying to use -f sdl but getting errors.

Subject: [FFmpeg-user] Any Mac OS X users interested in ffmpeg AppleScript
 droplets? - here's one for cat
Message-ID: <D07E893A.2B555%laine.lee@utsa.edu>

Concatenate similar video files using this AppleScript.

How do I use it?

Copy the lines containing +ACI-begin script+ACI- through +ACI-end script+ACI- to your Mac's clipboard. Paste the clipboard contents into a Script (or AppleScript, depending on your version of OS X) Edtor window, then save as an application. Name your video files successively, and drop them all onto the AppleScript application's icon.

What does it do?

Uses your compiled version of the ffmpeg executable to concatenate the files in ascending order, creating the resulting file in the same location as the files you dropped. The ffmpeg executable should be compiled using Homebrew+ADw-http://brew.sh/+AD4- and/or be accessible by your command line shell at /usr/local/bin/ffmpeg. You should be able to change that specification in the AppleScript if you keep ffmpeg somewhere else.

I+IBk-ve tested with .m4v files containing 5.1 audio. Please help me test others. Thanks.

Message-ID: <CANNTXGoQyX0Vp7b2B+YtWR6eGJUDiRfz6-TJ0XcA7yrLn_g0Eg@mail.gmail.com>

Hi list,

I'm doing audio/video analysis on videos downloaded from youtube. As part
of the process, I need to extract the audio to a form that can be opened by
my audio analysis software. I've been using mp3, but I recently discovered
that ffmpeg adds 0.12 seconds to the beginning of the .mp3 file. This
causes sync problems.

Here is the info on the youtube videos:

Stream #0:1(und): Audio: aac (mp4a / 0x6134706D), 44100 Hz, stereo, fltp,

Any thoughts on how to make sure that the extracted audio is exactly in
line with the original aac audio (unfortunately, my software can't read
aac)? Right now I am simply adding the offset onto my computations, but I
would prefer to have a reliable conversion.

Thank you very much for any help!

Message-ID: <CANNTXGoODq08C40gGXvhYAj4xQghiz+pKSA2FneWu_a1_GPH6g@mail.gmail.com>

Hi list,

I'm doing audio/video analysis on videos downloaded from youtube. As part
of the process, I need to extract the audio to a form that can be opened by
my audio analysis software. I've been using mp3, but I recently discovered
that ffmpeg adds 0.12 seconds to the beginning of the .mp3 file. This
causes sync problems.

Here is the info on the youtube videos:

Stream #0:1(und): Audio: aac (mp4a / 0x6134706D), 44100 Hz, stereo, fltp,
96 kb/s (default)

Any thoughts on how to make sure that the extracted audio is exactly in

Sorry, I misread that.  When playing the test file, in MythTV it depends on whether I have THX or Dolby selected (it plays the channels correctly in either).  It either shows:
THX Cinema 3/2.1
Dolby D 3/2.1

But in XBMC, no matter which of the two are selected, it simply says:
PCM 48kHz

As I mentioned I have never heard of PLII prior to this, and my receiver doesn't have anything about that.

The button actually has the Dolby logo and the letters DTS above the button, and the word "SURROUND" below the button.  I think that the way this receiver works is that you can select a mode, but if it gets a stream that is in a format it understands it will play it regardless of whether you have selected THX or Dolby/DTS.  However if you select Stereo or Direct, a relay clicks inside and I think the rear channels are completely disabled, possibly for those who have this receiver but only stereo speakers connected.

I think you are correct but as I say it plays exactly the same whether THX or Dolby/DTS is selected (within the same program).

Which is what makes me think that this receiver will let you select one or the other, but actually uses what it receives.

Keep in mind that all of this is with a S/PDIF (Toslink audio) connection; it might be different if the receiver had HDMI support, but it's not quite that new.

Thank you again and sorry for sending the wrong information the first time.

This indicates that MythTV really has a PLII decoder.

As said, I also tested with S/PDIF, only analog 
makes a difference here: I have to force stereo 
input on the receiver to allow PLII decoding.

Your ffmpeg command and the complete console output are missing.

 Thank for your response!

We tried employing ffmpeg without specifying -f option, but it yield us almost the same result.
How did you determine that only first three frame are decoded successfully?

With best regards,

I tried to decode the file with the reference 
decoder and it aborts after three frames.

I don't understand this.

I believe the reference decoder can be used to analyze 
the correctness of H264 streams.

Does the ffmpeg project have any sample/test data available of audio files
in the various supported audio formats?  I'd like to be able to try out
audio format conversions on the various formats that ffmpeg supports, using
a known good set of sample audio files.

There is the FATE testing system which we use for testing assorted
components of FFmpeg.  You can read about it here:
http://ffmpeg.org/fate.html

What exactly are you looking to test?  On sox-users you said you wanted
to test its filters on various inputs and you were told that sox
converts to in internal format.  ffmpeg (the tool) also automatically
converts formats between filters if neither share a common format.

That's understood.

This is the technicality which needs to be understood. If the source is
what Carl Eugen has identified, there is no digital indication that
this is "Dolby Surround". You will identify two channels which can be
played on stereo output, and will sound like a down-mix of surround
material on stereo. Yet in these two channels, there is a mixture of
four or six audio channels. If you know how to "decode" them, you can
separate them. Actually, you should be able to detect this surround
encoding if you analyze the audio waveforms, but this may mean actually
decoding them and checking whether the "extra" channels contain sound.
(My hardware decoder creates pseudo-surround effects from plain stereo
material by the way, due to the way it "tries" to decode 6 from 2
channels and the audio's phases.)

Actually, a lot of digital TV channels broadcast their movies with
surround sound like this, i.e. using two channels, but still containing
surround. Mostly this is the case when they don't have 6 channels
available. This is very common in broadcast, from my experience.

Basically, ffmpeg currently can neither detect nor decode this
encoding. I think decoding it would require something like an audio
filter.

Since it's easy to find algorithms (i.e. matrices) for encoding but not
for decoding, I am guessing that the latter may be a much tougher task.
It's not as easy as inverting the matrix. I'm no smarter than Carl
Eugen concerning this. Here's the only description I have found of the
process, and it looks very DSPish (if not analog):

See figure 5 for a summarizing diagram. No C source code provided
though. ;-)

Subject: [FFmpeg-user] Any Mac OS X users interested in ffmpeg AppleScript
 droplets? - here's one for cat
Message-ID: <D07F9C31.2B5D3%laine.lee@utsa.edu>

If you+IBk-re interested, here+IBk-s an OS X (Mac) AppleScript droplet source for
concatenating multiple video files using existing ffmpeg executable.

How do I use it?

Copy the lines containing "begin script" through "end script" to your Mac's
clipboard. Paste the clipboard contents into a Script (or AppleScript,
depending on your version of OS X) Edtor window, then save as an
application. Name your video files successively, and drop them all onto the
AppleScript application's icon.

What does it do?

Uses your compiled version of the ffmpeg executable to concatenate the files
in ascending order, creating the resulting file in the same location as the
files you dropped. The ffmpeg executable should be compiled using Homebrew
<http://brew.sh/>  and/or be accessible by your command line shell at
/usr/local/bin/ffmpeg. You should be able to change that specification in
the AppleScript if you keep ffmpeg somewhere else.

I+IBk-ve tested with .m4v files containing 5.1 audio. Please help me test
others. Thanks.

I might actually believe I was hearing pseudo-surround in MythTV if I did not have the one test recording that clearly and unambiguously states the name of each channel as it plays.  Apparently, by luck or by design, the MythTV people have stumbled onto a way to play these types of recordings correctly.  If they have figured it out, I would think it's not an impossible thing for someone who understands what they are doing.  But that said...

In the test file I have, on the video there is a line that says "Dolby E", which I never paid much attention to because none of the audio streams identify as ac3 format and because you could write what I know about Dolby on the head of a pin.  There is a page about Dolby E at http://wiki.multimedia.cx/index.php?title=Dolby_E but I do not know if it is applicable in this situation.

I also found mentions of Dolby E here https://forum.videolan.org/viewtopic.php?f=18&t=81323 and here http://www.videoredo.net/msgBoard/showthread.php?28982-Dealing-with-Dolby-E&s=9c4d4a18d25bf5b63595673bdaec178b

There is a program that supposedly can convert E-AC3 audio tracks at http://www.addictivetips.com/windows-tips/how-to-convert-dolby-truehd-and-e-ac3-audio-tracks-into-other-audio-formats-with-eac3to/ but it appears to be a Windows only program (there is a line in the article that claims that it works in Linux but when you go to this thread http://forum.doom9.org/showthread.php?t=125966 it appears to be a very Windows-centric program). A Windows program does me no good, especially if it in turn depends on the installation of other types of Windows software, because I have no computers running Windows (my desktop is OS X and the system I want to convert these files on is Linux).

I had originally thought that because the original file's audio is MPEG2 that perhaps something like mctooLAME (http://sourceforge.net/projects/mctoolame/?source=typ_redirect) would be helpful but the more comments I hear about it the more I suspect we are dealing with E-AC3 (Dolby E) here, though I don't understand how that can be possible if the audio tracks identify as MPEG2.

I understand that but it still begs the question of how MythTV pulls it off.  In case I didn't mention it, I am not a technically-inclined person and definitely not a programmer, so most of the material in the above links is way over my head.  I don't even know for sure that this is E-AC3 and I have not even found a utility that will positively identify E-AC3.  And yet it appears that somehow the MythTV people alone have it all figured out, at least as far as being able to play it correctly without the need for Windows or a bunch of additional software.

All of that was way beyond my understanding.  I don't know if any of the links I have provided above will prove to be any more helpful, but perhaps there will be something in one of those that makes sense to you guys.  I'm already in way over my head here - I had no idea that this might be something complicated, because I just assumed that if MythTV can decode these signals then it must not be too difficult.  But then I honestly have no idea what is actually involved, nor the slightest clue how MythTV does it.

I know nothing about this subject at all.  However the discussion reminded me 
of something that could possibly be relevant.

Steve Harris has one or two LADSPA effects for working with Dolby Surround, 
which may be what you're talking about here if I understand the most recent 
post correctly (I have not been following the thread)
.  Perhaps talking to him about this could be informative?

http://plugin.org.uk/ladspa-swh/docs/ladspa-swh.html#tth_sEc2.102

Then again, maybe that's the wrong tree to be barking up entirely, but I thought 
I'd point it out just in case it was good for something.

Regards,

Luke

The filter and the library are already there, 
they are just missing this functionality...

This looks like a Dolby PLII encoder, FFmpeg also 
contains a PLII encoder.
What we don't have is a decoder.

No, the test file does not contain Dolby E audio.
FFmpeg does not support Dolby E.

Please understand that Dolby E != E-AC3. E-AC3 decoding 
and encoding (up to six channels) are supported by 
FFmpeg.

That's actually the exact opposite:
"It allows you to encode four channels of sound into a stereo
compatible stream that will be decoded by a Dolby1 Surround/Pro-Logic
decoder into Left, Right, Center and Surround signals."

ffmpeg already (apparently) supports this, see "-matrix_encoding",
https://www.ffmpeg.org/ffmpeg-resampler.html 

The original poster needs the opposite, a decoder: 2 channels back to
5.1 (or 4.0).

I have been at a total loss when googling. The only free software I
have found is AC3Filter, http://www.ac3filter.net/ . I actually missed
this important sound, but see it now: It's open source, and claims to
be GPL2 (plus/minus the licenses of other included code). I'm still
skimming through its code though, looking for the code which
accomplishes the up-mix.

el_processor.cpp is not license-compatible but

PS: What did you google knowing that MythTV

Because it's GPLv2+, but libavfilter is LGPL? (Just checking, this

Reading the code may help to understand the original descriptions of
the methods needed to decode the 2-channel input (such as the article
and image I referred to, and possibly other whitepapers from Dolby
Labs), or find other references which mention Fourier transformation
for our digital domain. I didn't come up with that myself, but
should've. This could allow for a clean-room implementation. *shrug*

That's the part of the configuration _I_ didn't understand. I had only
jumped onto what you had concluded. ;-) I googled for surround
decoders, or dolby decoders, and omitting the MythTV fact didn't lead
me to MythTV.

Or you could ask the original author if he agrees to 
relicensing his code.

I opened ticket #4085 with the MythTV sample.

I can only get errors from mp3check:

Message-ID: <CAPz3gmnirj=bUVyM1_mU78gFjhDZ4KnGjy2pxGfVbQxwQHyWEw@mail.gmail.com>

Hi.
I'm trying to record some RTMP stream with FFmpeg to a FLV file or
something else.

I'm trying the following command:

ffmpeg -i "rtmp://94.47.147.130:1937/live/livestream" -f flv -t 60 test.flv

But I receive a 6 byte file which seems to contain only one frame.

This is a quite old version. I don't know if RTMP support was as good
back then as it is now.

2.4.x is current. please try to get hold of that, or use latest git if
you build your own.

The way you're doing it is not optimal.
a) For dumping streams to disk, "mplayer -dumpstream" is the
   recommended path. :-)
b) You're re-encoding. That may or may not be your intention. To retain
   the original quality, use "-c copy".

Actually, answer b) may help you even with your old ffmpeg version.

Please confirm that you tested with "-write_xing 0" 
and your results.

Please understand that I should have realised this 
from the beginning but since you insisted on FFmpeg 
writing frames larger 320k I concentrated on that.

Sorry, Carl Eugen

hi,
I am confused how ffmpeg  allocate it's cpu resource when i am using ffmpeg
to transcoding, 

for example:
   how much resource to decode, and how much to encode

I have set the threads to 1 and do a experiment:
ffmpeg2.1 -i /home/mps/chd/out.avi -acodec pcm_s16le -ar 44100 -ac 2 
-vcodec libx264 -coder 1 -b:v 250k -x264opts

/home/mps/cmwu/passlog_1414744300_h264_1.log -f null -y /dev/null

I found the cpu load use is 140%, it's not 100%

Can anybody explain it for me ?

AFAIK threads 1 is meaning 1 Core for Encoding. So the extra 40% is used for decoding, logfile/IO activity and Audio stuff.

Due to some hardware limitation, the my video capture box captured video in mp4 format with slightly different fps
such as ranges from 59.21 and 60.01.

1. why would a machine have fluctuating fps like this?
2. how can i join them without reenoding them?

If you don't want FFmpeg to decode (!) with 
automatically chosen number of threads (as many 
cores as you have), tell it with:
$ ffmpeg -threads 1 -i file

hi all,

    I'm using ffmpeg command line tool to convert video, (FYI, i'm not just
use it in shell, i use a module
<https://github.com/senko/python-video-converter> that execute a ffmpeg
command as a subprocess), and when i execute ffmpeg process one by one,
everything was all right, but, when i execute 5 and more processes
concurrently, things went bad.

    One of the error is  "Invalid data found when processing input",
another is ffmpeg process exit with code 1.

    This is my command.
    "usr/bin/ffmpeg -i 20130804_100547.mp4 -hls_base_url /test2/ts/
-hls_time 10 -hls_list_size 0 -vf transpose=1 -y small.m3u8"

Complete, uncut console output of the failing command

Message-ID: <CAM+h0VtaN4qTpBmbrJxhEZ_QZ+R8vPyqgv3a07iKn3P-g-efiA@mail.gmail.com>

Hi,
I am testing *ebur128* filter, which can produce a video output. But I need
a simple *vumeter* display per audio channel, which does not seem to exist.
Any idea to accomplish this?

So far, I have only been able to *volumedetect* per frame, mentioning a -ss
time and a duration with -t 0.04 (for 25fps)... So I can get a peak sound
level as text output using volumedetect. But this is not very efficient.
All I need is a video and 2 rectangular bars, which have their lengths
connected to input audio level.

Any ideas on doing this?

There is a momentarily ebur128 level in the ebur128 video output so you could crop that out and reuse it noting that the concept that it measures is differently than a typical vu meter. Here?s an example where I split a stereo input and have two side by side momentary ebur128 meters:

ffplay -f lavfi "amovie=stereo.mp3,channelsplit[a][b];[a]ebur128=video=1:meter=18[a1][out0];[b]ebur128=video=1:meter=18[b1][out1];[a1]crop=20:432:612:40[a2];[b1]crop=20:432:612:40[b2];[a2][b2]framepack[out2]?

From here you could use drawbox and/or drawtext to add labelling.

Thanks Dave,
But there is a minor issue with ebur128 Momentary level. It is defined for
a 0.4 second time range. Which is very long compared to 0.04 second for
each frame in PAL standard. Do you think that there would be a possible
workaround to hijack ebur128 Momentary (0.4s) vumeter, to use 0.04 second?

Yes, MPEG-2 Multichannel was probably never formalized 
for DVB, Dolby PLII certainly was.

And it is apparently possibly to detect it;-)
(I did not yet test if the flag is really set 
correctly.)

I am asking just in case feeding latm encapsulated aac to fdkaac is in 
someway possible - in which case I need to try harder.

Anyone can say yes or no?

Thanks.

Yes, it is (afair).

Why?

I believe you know what I am usually (always, in 
every single email) asking here: No, I don't do 
it to make user's lifes as hard as possible but 
because it is needed to provide a useful answer.

Several developers agree on irc that the extended 
ancillary data syntax is typically unused and 
cannot be used to detect PLII encoding.

:-) yea though if the answer was just no it would have saved extended 
experements.

I haven't tried loads of variants yet but for now -

first without fdk - file plays ok with players also.

Sorry, I mixed something up:
The fdk encoder supports latm encoding (which 
doesn't work with any other of the four aac 
encoders) while the fdk decoder cannot support 
latm: There should be parser / demuxer that 
changes latm into aac but when latm decoding 
was implemented in FFmpeg, it was decided to 
do it in the native aac decoder which is not 
was libfdk does / expects.

Sorry, Carl Eugen

Ahh, Ok - thanks for the info.

Would be a handy feature.

FWIW wanting to use fdk is related to the etsi doc I posted in the other
thread.

I was going to try and add some debugging to see what, is any, ancillary
was broadcast in the UK (like heavy compression and mixdown). I know
from adding debugging to ffmpeg aacdec that drc is broadcast, but
couldn't find mix down meta.

Fair enough - I was suprised that anyone actually broadcast prologic.

It would be interesting to know if the sample was flagged.

Maybe MythTV just lucked into passing it out as spdif - I don't have any
experience of myth.

Do you have a specific problem with the internal 
decoder?

The thread was not aac-related and people seem 
to agree that the dvb feature you pointed at is 
not actually used.

The info you pointed to is related to mp2, not aac.

Where I live all movies are broadcast PLII.

As said, it doesn't help to check the flag because 
it is mostly unused.

As said MythTV contains a PLII decoder (filter).

"Broadcast" is a relative term here.  It is very common for use in free-to-air C-band and Ku-band satellite transmissions in the United States.  That may or may not be considered "broadcast", depending on how you define the term.

It doesn't do DRC so if I want to use my big old stereo speakers (my TV
speakers are crap) to listen to a recorded film it would vary between
being too quiet and too loud.

As I guess you know the default for 5.1 should be full drc applied and
mixdown to 2.0 makes it even more essential as (I believe) the act of
mixing down increases dynamic range.

It's the (unparsed by ffmpeg) ancillary data aspect not the specific codec.

Yes I know, but right next to it is about aac in fact it was searching
for aac stuff that found me that doc.

The code that was responsible for this compilation 
problem was removed from the FFmpeg source.

Note that afaik, the error indicates that libm.h 
and libm (the header and the library) have 
different opinions on what symbols they provide.

Subject: [FFmpeg-user] Confusion about pix_fmt
Message-ID: <546096CC.5090304@binarykitchen.com>

Hello guys

If you look at the bug report at https://trac.ffmpeg.org/ticket/4098 you
can see that I am confused about the pix_fmt option.

I am not sure what parameter to use for this option. All I want is to
make the video compatible on *modern* browsers/players only and I also
want to make the warning disappear ffmpeg is generating:

deprecated pixel format used, make sure you did set range correctly

This warning led me to believe I have to set a different pix_fmt
parameter than the default one (yuv420p). But I do not know which one.

Any clues?

Michael

yuvj420p and yuv420p are the same.  If a video player can play one it
can play the other.

The "j" refers to the range of values that are output.  "j" is full
range (or PC range) meaning it uses all 0-255 values rather than the
more common 16-235 range (which is known as TV or Studio range).

The problem comes when converting to RGB on playback.  All good players
recognize a flag in the file indicating that it is full range and
convert it properly.  All bad players do not.  They assume it is TV
range and expand the range of values causing too high contrast which is
noticeable.  Another similar symptom is players that do not expand the
range when they should leading to too low contrast.

I do not know whether browsers fall into the good category.  If you want
a correct picture on every possible system use yuv420p.

If you want to know more about the colour space and this "j" option I
suggest you read these:
https://en.wikipedia.org/wiki/YCbCr
https://en.wikipedia.org/wiki/YCbCr#JPEG_conversion

Then you have to use "-pix_fmt yuv420p" which is 
different from "yuvj420p" and I believe "good players" 
are rare.

As said, this is not possible: The warning appears if

This have solved the problem, although since In my system I have an old 
version where this flag is not available I haven't tested.

Now I need to go to the Amarok and see what's can be done to track down 
this problem.

So it does, I couldn't find it when I first looked.

Doesn't seem very much compared to the quite complicated looking
descriptions of what a "real" decoder supposedly does.

float lt      = *samples++;
float rt      = *samples++;
bufs->l[ic]   = lt;
bufs->lfe[ic] = bufs->c[ic] = (lt+rt) * m3db;
bufs->r[ic]   = rt;
// surround channels receive out-of-phase
bufs->ls[ic]  = (rt-lt) * 0.5;
bufs->rs[ic]  = (lt-rt) * 0.5;

I don't pretend to know what should happen - but it's obvious that that
leaves the S in the fronts - but then you said your receiver did
too. I wonder if all receivers would.

Where I live - Germany - the "minor" stations try to use less bandwidth
on the satellite transponders / in their bouquets, and transmit only
one AC-3 audio stream with two channels. Nevertheless, I get quite
proper surround sound from my sound system during many movies. So my
conclusion is that they use the PLII "down-mix".

(Unless that statement was a misunderstanding and we're talking about
something totally different.)

That looks different from what we were looking at earlier in the thread
(and far too simple). Carl Eugen had pointed out this file:

https://github.com/MythTV/mythtv/blob/master/mythtv/libs/libmythfreesurround/el_processor.cpp

and its main worker function is block_decode(). It's far less simple
than your example, and sort of corresponds to my understanding of what
a decoder needs to do. You can't just add and subtract left and right
channels. Since you have to work with phases, you need to do FT when
operating in the digital domain. (From what I still know from my
studies in electrical engineering.) And that's what this function does.

Nevertheless, there's an implemention there! And even open sourced.

> I don't pretend to know what should happen

Disclaimer: I do honestly mostly pretend to know, but I really don't
know much. ;-)

That doesn't make any sense.  AC3 5.1 is usually done at 384 kbps, while
AC3 2.0 is 192 kbps.  The 192 kbps difference is a drop in the bucket
compared to all of the other packets that make up the transponder mux.

Weird.

I think you're right - I was (stupidly) trying to make sense of it. All
I do know, e.g.: The "major" channel "RTL" uses various audio stream
types in its programming on the SD channel, depending on the type of
show and the material. The minor channels, such as "RTL2" only ever
have one MP2 audio and one AC-3 audio stream, with two channels each.
For whatever reason. (We might need to use other examples than these
two channels, but I'm speaking or "relatives" in a family of channels.)

BTW, the major (SD) channels also get much more overall bandwidth than
the minor ones, resulting in very sharp video quality (or rather quite
sucky video quality on the latter channels). I don't know exact
numbers, but I believe there may be more than a 2x factor. Audio is
probably still said drop in the ocean.

Ah, this piece of info was missing before and that is the video is SD, not
HD.  It isn't weird to have only AC3 2.0 for SD channels.  I was thinking
in the world of HD.  Silly me.

Agh, thanks for that - the code I posted is from myth, but obviously I 
don't know if it's ever used.

For some reason this thread has split into two for me and I didn't see 
the other bit.

It is certainly correct that many German-speaking 
TV channels use PLII down-mixing.

Maybe some of you want to add information that you 
find in the MythTV source to ticket #4085 to allow 
a LGPL implementation of the feature?

JFTR, I've finally managed to compile ffmpeg for MIPSEL UCLibc using a third
method, the second using cross-compilation, and the results were identical
to the previous cross-compilation.

This indicates to me that the problem lies in the ffmpeg source code and/or
configuration itself.

Accordingly, I note and welcome that ...

Would that be ffmpeg-2.4.3.tar.bz2?

With identical, do you mean that you still 
get an error concerning fminf()?
In this case, you probably tested an old 
version.

Note that afaict, a system header (libm.h) is broken 
and you apparently cannot fix it using another library.

Please read http://ffmpeg.org/download.html and 
please us if you find it unclear.
(I actually find it unclear but it still says 
how to download a current version.)

Subject: [FFmpeg-user] http timeout not working?
Message-ID: <CAGC9P7ZfuQtxcmz+JkgMnwp3YRD2Es_LpTx78bQ1pw8imyk=iw@mail.gmail.com>

I'm using ffmpeg to capture video from an ip camera using:

ffmpeg -y -f mjpeg -analyzeduration 0 -probesize 32
-use_wallclock_as_timestamps 1 -timeout 10 -i http://user at 1.2.3.4/video.cgi
-vsync passthrough -vcodec libx264 -pix_fmt yuv420p -t 30:00 output.mp4


Everything is working fine, except if the camera is disconnected. For
example if I unplug the camera, ffmpeg will just hang, it won't ever exit
as far as I can tell.

It seems like the timeout value should cause ffmpeg to stop if it hasn't
received any data on the socket in this time period, but it doesn't seem to
do anything. Am I setting it incorrectly?

Thanks for any help,

Brandon

Just to avoid a misunderstanding:
These binaries are not provided by the FFmpeg project.
(We are very thankful to relaxed though.)

The FFmpeg project does not provide any products.

(This is not a bug in FFmpeg but in an ancient broken

This malicious option takes ns so you probably want:

You can get RPMs from RPMFusion:
http://ubuntupop.blogspot.de/2012/10/how-to-add-rpm-fusion-repository-on.html

But as I pointed out here:
http://article.gmane.org/gmane.comp.video.ffmpeg.user/53385
those are very old versions. You are better off building your own.

I tried your suggestion for various values, 10000, 10000000, etc but do not
seem to get any different behavior. I forgot to mention earlier, if it
makes any difference, I am running ffmpeg on windows with the binary build
from ffmpeg.zeranoe.com. I can attach the console output if it would help,
but even with debug output on, everything seems to be running normally then
everything abruptly stops when the camera is disconnected.

Any idea what might be going on?


Thanks,

Brandon

Great, thank you for the information!

Consider running the fate self-test to confirm 
that your binary is working fine, this is 
trivial if you compiled natively on your target 
device, if you want to run fate after 
cross-compilation, you have to mount one 
directory on both the host and the target and 
have a working ssh connection that doesn't 
need keyboard authentication. Then use the 
configure options --target-exec and 
--target-path. I will try to help you if 
necessary.

Message-ID: <CAF4t7AM5V7AC_AzcyGtun0bciR9uk-9EwtmsA4+d5V2XmDVw5g@mail.gmail.com>

Hello,

I am practising to learn about ffmpeg API by making small applications that
use ffmpeg libraries. So far I have successfully made simple applications
for codec conversion by simply including libavformat/avformat.h and
libswscale/swscale.h libraries into my project. Now I intend to make some
simple media streaming applications. I have been reading ffserver.c source
code to get ideas from it. The problem is that I cannot include libraries
such as network.h into my project. However avformat and avcodec could be
easily included. I looked into the usr/local/include/libavformat path and
noticed that it only contains three headers of libav into it (namely
avformat, avio and version). I manually copied network.h into this folder
but now I get the following error :

/usr/local/include/libavformat/network.h:27:20: fatal error: config.h: No
such file or directory

I suppose that error is because network.h has dependencies to config.h. So
now I searched for config.h and apparently there are plenty of files named
like this and I don't know where to copy them.
My question basically is that do I have to copy all headers into
usr/local/include/ path? Is it safe? Or how else can I include necessary
libraries into my project?
I am coding in C++ using Eclipse IDE and I use "extern "C" {}" to include
these libraries into my project. Besides this, I have also already set the
-l arguments in project properties. The problem is that is works for
avformat.h but not network.h.

Any help or guide would be highly appreciated.
Thanks

I want to do screen recording with FFmpeg (on Windows). It works fine 
with "gdigrab" but the output file size is quite high.

What video codecs are available that give good compression for screen 
recordings while maintaining a good picture quality (screen text remains 
readable)? Maybe anybody has created a nice MP4 profile for it?

Command line and complete, uncut console output missing /

I don't think the container has any relevance for the 
file size and the best encoders may not work with mov.

avformat.h and swscale.h are headers, libavformat and 
libswscale are libraries.

network.h is another header of libavformat but an 
internal one that you should not need to include: 
libavformat contains network functionality that 
you should be able to use without including this 
internal header.

It is a bug that ffserver includes the header, if 
you want to copy the bug, you will either have to 
provide a config.h header for your needs or making 
your project part of the FFmpeg source structure 
(like ffserver.c). Note that the second solution may
mean that you cannot distribute the resulting binary 
under a different license than the LGPL (or GPL).

An alternative would be to send a patch to the 
developer mailing list to make the needed 
functionality public but I suspect this will not be 
easy.

I tested FLV and MP4, see attached log.

I meant a x264 profile but now I realize that the binary I use doesn't 
include this codec. Will get an updated one.

Neither are encoders imo but see below.

I am surprised now:
You wrote originally "I want to do screen recording 
[...] but the output file size is quite high".
I was assuming that you meant lossless encoding in 
the rgb colourspace. For lossy encoding (flv1 and 
mpeg4 only support lossy encoding), you can get a 
smaller filesize by either specifying a lower bitrate 
or requesting a higher constant quantizer.
As you already mentioned, the best lossy encoder 
(with acceptable encoding speed) is x264.

If you want lossless encoding that keeps the original 
colourspace (rgb), please test png, ffv1, (ff)huffyuv 
and flashsv2. Then also test x264rgb with the lossless 
option. (The filesizes may be very significantly 
higher in all these cases than what you saw with the 
lossy encodings you tested, this is not unexpected. 
The files may be smaller depending on what you 
record.)

When testing with a recent version of FFmpeg with x264 included the 
output file size decreases significantly (see attached log).

Sorry for the noise.

If your input is rgb and you don't care about compatibility, 
please don't use yuv444p but -vcodec libx264rgb to get higher 
output quality.

The recording doesn't need to be loss-less, I just want to make 
screen-casts to communicate GUI application issues to my colleges. To 
minimize the network upload time I searched for file size optimizations.

Hi
I suppose that, x264 has a lossless mode when the quantizer scale is set to
0. If that is also applicable to libx264rgb, then it is worth to look at.
So your pixels will still stay rgb, and you will have x264 efficiency in
lossless mode.

I understand.
If your input is rgb, do not use -vcodec x264 with 
yuv444p colour space but -vcodec libx264rgb which 
allows higher quality (or smaller file size).

Both (yuv444p and rgb) will not work with all players.

I would also give a shot for *quicktime animation* codec *(-vcodec qtrle)*.
Which can be lossless. But you have to test for file sizes. Which one gives
you better file size and minimum cpu load?

 From a quick test it seems that "-vcodec qtrle -g 60" is about the same
size as "-vcodec mpeg4". The video bitrate is around 1200-1400kb/s. With 
x264 the bitrate is around 400kb/s.

Message-ID: <CAHVD1iZ_D_uTaWNeGOZAm_JSxsov2ir7duA_C+D-scbUVsb81A@mail.gmail.com>

Hi,

My understanding is that when a new Container object is to be initialized,
it always requires an I-frame + subsequent P or B frames to initialize else
open fails.

My question is, how do we use the same Container where there is
a continuous stream of set of I-frame+P/B frames, I-frame spaced at GOP
interval (this is a real-time video stream use case), whether it is
possible to use the same Container without re-initializing it (i.e. I do
not want to initialize/open the Container object each time).

I want to know if it is possible to reuse the same Container object while
we keep feeding it the received encoded frames into the Container's input
buffer. This way, we do not wait for accumulating a set of I-frame+P/B
frame block and then give it to the Container for decoding.

This approach is to avoid the receive buffering to improve the processing
time. We assume some amount of de-jitter buffer to order the received
frame.

Valid (h264) streams exist that do not contain I-frames, 
only P- (and B-) frames.

I unfortunately don't understand your question, not even 
if it is decoding- or encoding-related.
Could you explain what you are trying to do and what 
doesn't work?

It is only (always) lossless but Tobias wants lossy 
encoding (which is unusual for screen capturing).

Hello Carl,

In my implementation, the encoder is generating the encoded frames and
building video chunks, which contains I-frame, P(B)-frames. We are
configuring a # of frames per this chunk as well as GOP interval (interval
for I-frames). On decoder side, we are decoding this video block to get the
pictures and display them to get the video play.

As you can observe, block building is a process of accumulating a number of
frames, and it takes a time (number of frames x 1/frame rate ms). This is
adding to the overall end to end latency.

My question is, is it possible to use just one Container and feed it the
frame by frame data so that the buffering or block logic can be avoided?

Can you also elaborate what do you mean by - "Valid (h264) streams exist
that do not contain I-frames, only P- (and B-) frames."?
  - When does an I-frame is used?
  - What is the notion of GOP interval and how it is used? Or is this a
container level feature? How it is related, if it does?

Hope this is more clear.

/anil.

I meant that streams without any I-frames exist and 
are valid. (I don't know if this has anything to do 
with your question.)

>   - When does an I-frame is used?

In frames without I-frames, I-frames are never used.
Recovery points exist instead, but they can be 
P-frames.

I don't now if GOP intervals have any relevance in 
such a case (probably not).

Dear Folks:

First of all, this is an awesome program!

I am using ffmpeg and ffplay combination to display a mosaic of 12 videos. I am using shortest=1 option to ffmpeg to stop all videos when the shortest video finishes. I need to play all the videos in a loop. Can you please suggest the correct way.

Here is the shortened command (for 2 videos) :
-----------------------------------------------------------------
#!/bin/bash
ffmpeg -i a1.avi -i a2.avi -filter_complex "nullsrc=size=1440x1080 [base];[0:v] setpts=PTS-STARTPTS, scale=480x270 [pos0];[1:v] setpts=PTS-STARTPTS, scale=480x270 [pos1];[base][pos0] overlay=shortest=1 [tmp1];[tmp1][pos1] overlay=shortest=1:x=480" -c:v libx264 -f avi - | ffplay -

It appears that ffmpeg does not fully support the discontinuity indicator in the afc. It does ignore discontinuity in the continuity counter, but it should also ignore a discontinuity in the PCR (and PTS/DTS). Is this a known issue?

But destination file has an interlace artifacts, unacceptable...

I have tried some command but nothing works, I can't even find good solution
on web/ffmpeg manual.
Can somebody help me which filters/options I should use to get XVID

Or maybe I should deinterlace mts file to 1440x540p 50fps file and convert
to progressive xvid?

You have no video devices so there is no possibility of using one to
capture the desktop.  Read that wiki link a little better.

Thanks for the reply, James.

Sorry, but I didn?t know that the video card wasn?t a DirectShow video
device.

Sorry, I was probably more terse that I should have been.  A "device" to
DirectShow has quite a specific meaning.  You can see the two inputs to
your soundcard there because something has created/installed the two
devices in DirectShow.

You can do something similar for desktop video capture.  The wiki
article links to one such utility on github.

That change looks wrong -- "ppc" => '#');
should be "ppc" => '#',

Many thanks for your reply, James.

I didn?t know that it was a software issue. I don?t have admin rights at
the computer in which I would record the screencast. So I adding a
DirectShow device is not a option for me.

I don?t have much Windows knowledge. But I had recorded screencast with
Camstudio before (this seems not to be an option anymore). Is there now
way to use ffmpeg with VFW? Sorry if write nonsense, I?m guessing.

Many thanks for your help,


Pablo

Hi,

Now ffmpeg can be compiled with support to gdigrab device. You can record the whole desktop or any portion of the screen.

Subject: [FFmpeg-user] Unable to produce a yuv444p video that vlc will play
	back correctly
Message-ID: <54689A5C.8030200@rabbit.us>

Hi!

This is not strictly a question on ffmpeg itself, as it may be the fault 
of vlc. But since vlc uses the same backend it is all somehow related.

I am trying to create a video which will display in full RGB color on a 
random player (in this case vlc). No matter what I do - I end up with 
color loss (likely yuv420 conversion) somewhere along the road. I have 
irrefutably verified that my video file contains the full color 
information, because I can do:

source image
   \
  video
     \
   extracted frame

and I end up arriving at the same source bytes (described in detail below).

However playback of the generated video and original/extracted images 
show a noticeable color loss when displayed side by side (screen capture 
in file side_by_side.png). What am I missing?

Thank you!

==== Follows description of the testing method

All (very small) files described below are attached to this message. The 
sequence of events:

I start with a small image:

This results (as expected) in a file identical to the source, proving 
that the video contains the full RGB (or equivalent yuv444) set of color 
information:

> ~$ diff miniansi_orig.png miniansi_frame.png; echo $?
> 0

Yet the results of playing the generated mkv in vlc (or for that matter 
any other player) are visibly terrible (see side_by_side.png)

Many thanks for your reply, Velotiaray.

Which would be the option?

You need to add ' -flags +ildct+ilme'.

With -c:v libx264 you also can (should) add the bff/tff option; although
personally not familiar with ffmpeg XVID encoding myself you might want to
look for something similar.

Only for this sample, not that it really matters in this case, but rgb
-> yuv will loose colour and there is also a conversion from full range
to studio and back.

It's the player or rather the way it works/is setup/is setup for your
hardware.

Players by default will use GPU for CSC/scale and these often won't
avertise 444 as an input option so VLC will likely convert to 420.

There is likely some way you could get VLC to do it, with mplayer  I
think specifying opengl would do.

I don't really know what to suggest - 422 would  be more likely to work
- but then you would still see some loss.

I am replying in-line further down, but wanted to to ask a generic 
question, just to make sure I fully understand what is actually going on:

In 1997 Intel came up with the MMX instruction set which among other 
things allows in-hardware rgb->422/420 conversion. Since then all 
players default to this on a virtually hardcoded level, and the GUI 
subsystem is expected to convert everything back to rgb (using the very 
same instruction set).

As a result of the MMX success, everything in the digital video world 
*17 years* later is inescapably doing this rgb->yuv->rgb dance, even in 
the case of 100% correct and complete metadata. This is true for all 
cases including the situation when both the source and the destination 
are operating in the RGB24 colorspace: CGI produced under an RGB 
renderer, to be displayed in a web-browser player, which by definition 
operates on an RGB device.

Did I get the state of the art about right?

You are actually correct - the conversion that took place is 422, not 
420 as I originally thought. Verified by:

> ~$ ffmpeg -hide_banner -i miniansi_frame.png -f matroska -pix_fmt yuv422p - | ffmpeg -hide_banner -i - -pix_fmt rgb24  minansi_yuv.png

and then comparing the way miniansi_yuv.png looks to the actual playback 
in a vlc window.

I added:
ffmpeg.exe -n -i "%%F" -c:v mpeg4 -qscale:v 4 -vtag xvid  -flags +qpel
*+ildct+ilme* -acodec libmp3lame -b:a 320k "%%~dF%%~pF%%~nF.avi"

but ffmpeg crashed.

So i tried -c:v libxvid but not worked (libxvid doesn't encode interlaced
video :/)

so finally I revert to xvid but remove +qpel filter.

It seems that the combination of +qpel+ildct+ilme crashes ffmpeg (with xvid
encoder).

Thanks and regards,
rp

Many thanks for your reply, Velotiaray.

>From what I read in the documentation I wonder whether this settings
would work to capture both video (with mouse) and sound from mic.

ffmpeg -f gdigrab -framerate 6 -i desktop -f dshow -i audio="Microphone"
-vcodec libx264 -crf 0 -preset ultrafast -acodec pcm_s16le output.flv

Sorry for asking basic questions, I only use Windows at work.

I don't think this script is part of the FFmpeg 
sources.
Please understand that only unpatched FFmpeg, 
running our configure script and make is 
supported on this mailing list.

If you believe that our configure is missing a 
needed feature, please tell us.

Though it was advertised for multimedia and SIMD is handy I don't
believe it's why yuv is used.

That's from broadcast for bandwidth reasons and given that practically
all "real" video is yuv then it needs converting to rgb if that's what
the display takes.

Using CPU with or without SIMD to do yuv -> rgb is typically last resort
of players as for a long time graphics cards/chips have been able to do it.

I think the MMX bit is a distraction. It's not impossible for players to
do RGB direct, but you are using mpeg codecs which were really made for
real video/broadcast which is still yuv.

The example of CGI straight to browser is probably not typical, but may
become more so - it's possible that solutions already exist.

Normal CGI as used by broadcast whether overlays or films would be made
so as not to expose subsampling artifacts - eg not using 100% colours
which suffer most AIUI (something to do with working with gamma
corrected vs linear light in addition to the actual res loss).

+1 to vlc some players could go straight for 420 as the lowest common
denominator.

You can't say that everyone would see the same result though, as it
depends on the hardware/set up of the users machine.

Please test mplayer -vo gl
And please use -vcodec libx264rgb for best quality.

I don't think your colour issue has anything to do 
with MMX.
All codecs (that have any relevance) only support 
yuv420p in the variants supported by the "free" 
(as in beer) multimedia players, so it makes sense 
for FFmopeg to default to yuv420p if nothing else 
was specified and it makes sense for video drivers 
to only support yuv420p.
Note that even vlc has / had issues with h264 rgb.

If you don't want interlacing artefacts in your output 
file but your input file is interlaced, you need to 
add a deinterlace filter to your command line, please 
test -vf yadif.

Please don't top-post here, it is considered rude,

The console output will tell you:
If the start times are wallclock, audio and video will 
be (should be) in-sync, if not this is hard / impossible.

Message-ID: <A6B9110A-908D-42D5-82B9-E9AC4135D4A2@cs.ucl.ac.uk>

Hi,

I am trying to compile ffmpeg on OS X so that it is portable. To be precise, after compilation, all references within the library should be relative, rather than absolute. My current naive approach was to compile ffmpeg with homebrew and try to copy the files over where I need them. This does not work for files like libavformat, which references libavcodec with its absolute, rather than relative path, which then leads to import errors like

Library not loaded: /usr/local/Cellar/ffmpeg/2.4.2/lib/libavcodec.56.dylib
  Referenced from: /Users/peter/anaconda/lib/libavformat.56.4.101.dylib

(/Users/peter/anaconda/lib/libavcodec.56.dylib exists. I deleted /usr/local/Cellar/ffmpeg/2.4.2/, so its not a PATH issue)

Is there anything I can setup in the configure file to compile ffmpeg in portable mode?


Thanks,

Peter

You should compile every dependencies in static mode (bigger files).

I also just realised that the advice I gave you was wrong. That was
aimed at how to properly make interlaced encodings, which in fact is
what you are trying to get away from. Sorry for that, and Carl's
advice for adding (only) a deinterlacing filter is therefore spot-on.

Many thanks for your reply, Carl Eugen.

Besides from the fact that audio device wasn?t detected (but I forgot to
copy the complete output), from your message I wonder whether I should
use_wallclock_as_timestamps as an option (sorry, but this is all Greek
to me).

Which value should it have in an old and slow computer? (I mean, when
the option is required to keep synced audio and video.)

Many thanks for your help,


Pablo

It appears that ffmpeg does not fully support the discontinuity indicator (DI) in the afc. In libavformat/mpegts.c::handle_packet(), if the DI is set, it does ignore discontinuity in the continuity counter.

But it should also ignore a discontinuity in the PCR (and PTS/DTS). Is this a known issue? I see that the default for ffplay is to ignore the pcr, but if the afc discontinuity indicator is set, then the pts and dts should also be allowed  a discontinuity.

Dear Folks:

I am using ffmpeg to create a video mosaic, the overlay is working fine.
I have a question though:

If one of the video streams does not exist, how can I tell ffmpeg to use a default
video stream? Right now, if the input file does not exist, ffmpeg exits.

Thanks,

No, is was very OK, I want to make interlaced encodings. Thanks :).
I prefer to make interlaced encoding, because 25 interlaced frames is
better (smooth motion) than 25p, so I prefer to stick with it.

Message-ID: <C02450D9-6206-4A4D-A74C-198AF59132DC@gmail.com>

I have a h264 file, which I obtained by capturing bytes streaming (mid-stream) from an IP camera.  

mplayer has no trouble playing the file on-screen.  However, I cannot seem to get ffmpeg to recognize and decode the file (or re-encode it into something else), no matter what combination of command line parameters I try.

Example output from ffmpeg is below. As I said, these are h264 bytes captured mid-stream, not necessarily on the key frame boundary.  mplayer (with no other options) plays the video just fine, which leads me to believe it is essentially valid. But for someone reason ffmpeg can?t figure it out.

Help would be appreciated! Thank you.

Subject: [FFmpeg-user] construct mov from a fragmented mp4 stream.
Message-ID: <CAHyWgmBj4LdFa1TM2iUdGzdKKhz2W5V72h35gsEGiwENrgPQ_Q@mail.gmail.com>

Hi all,

I have a fragmented mp4(H.264) stream dumped to file. It has several atoms
of the following sequence.
moof
  mfhd
  free
  traf
    thfd
    trun
mdat
moof
 :
 :

How can I create a MOV file out of these fragmented moof atoms.
I think that I have to extract H.264 data from moof atoms and dump them in
to moov atoms of a MOV file.
Is this possible with ffmpeg.
Actually I need to achieve this programmatically, but first I want to know
if this is  possible with ffmpeg.

Thank you in advance.

Hi list members!

I'm trying basic Movie playback with ffplay.  When I execute the following command, I got the warning "Parsed_pan_0 This syntax is deprecated. Use '|' to separate the list items".
What this waring mean and how should it be?

I have searched ffmpeg documentation on the net but I can't get the answer!

Use "|" instead of ":" to silence the warning.

Just to make sure: You do know that this is not the 
best way to downmix, you are using the pan filter 
because you know exactly what you are doing?

Thanks Carl.  I have changed the command and it works without waring.
 
ffplay -i ~/Movies/More\ Than\ You\ Know.mp4 -af "pan=stereo|FL<FL+FC+BL+SL|FR<FR+FC+BR+SR"

I think online documentation should be fixed.  How do you think?

https://ffmpeg.org/ffmpeg-filters.html#pan

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

Well, I have got use pan filter just a result of try and error.  https://trac.ffmpeg.org/wiki/AudioChannelManipulation seems to suggest me to use -ac 2 option, but my 5.1ch mp4 does not play full audio with -ac 2 option...

Or is there correct way to downmix audio any other?

If "-ac 2" does not work for you, please discuss it here, 
I don't think the pan filter does downmixing in an 
acceptable way.

A simple "ffmpeg -i <partial_mp4.mp4>" command fails with the following
error.

[mov,mp4,m4a,3gp,3g2,mj2 @ 00000000042e1e60] could not find corresponding
trex
[mov,mp4,m4a,3gp,3g2,mj2 @ 00000000042e1e60] error reading header
samples\fragMP4.mp4: Invalid data found when processing input

Is there any specific way to achieve this in ffmpeg.

I have had one lying around here for the last couple of weeks - ever
since I got annoyed by that warning. (See some other thread here.)

I don't recall why I didn't submit it. I think I was annoyed by the way
pan handles arguments, but that can't be fixed without breaking
backwards compatibility.

Patch for documentation?  Just replace ":" with "|"?

If I can write documentation, based on Moritz's comment, there seems to be backward compatibility right?

Does it mean the latest documentation can't be provided for ffmpeg?

Should I open new discussion about "-ac 2"?  Or continue with this thread?

Briefly, the source is DVD dumped with mplayer and ffmpeg down-mix audio with "-ac 2", but if didn't down-mix with ffmpeg, ffplay seems to need pan filter to playback.  Using "-ac 2" with ffplay dose not help.

Thanks Carl,

The h264 file can be downloaded here:

https://s3.amazonaws.com/bryanfe/vid.h264 <https://s3.amazonaws.com/bryanfe/vid.h264>

So as to clear any confusion if you watch it ? it is just a camera pointed down at a wood desk, with a red light flashing in the background (not very exciting).

That's basically it. See attached. Too lazy to format correctly and
properly send to the correct list right now, with comments. Might do so
later.

No, my comment regarding backward compatibility was based on something
else. Doc can be fixed to reflect current behavior, period. Attached.

Subject: [FFmpeg-user] FFM moving time segment
Message-ID: <5A651CA75E25F940A89A85F2A41F388D8C0A76@EXCHANGE-DB2.msdtech.net>

Hello,

I am trying to send an rtp multicast of a stream with the configuration below. It works; however, when the max file size is reached (or the disk fills up if that parameter is excluded from ffmpeg) the program ends.  The desired behavior would be to just keep a small section of the stream as per the docs the ffm file can "store a moving time segment of an infinite movie or a whole movie."  The current behavior confuses me as clients are able to play the sdp file and receive the content from the beginning which seems inconsistent with multicast. How do I make ffmpeg create an FFM with a moving time segment of an infinite movie?

Thanks,
Eric

Dear Folks:

I am creating a Video mosaic as follows. Unfortunately, after the video ends, everything stops. I would like to play all the videos in a loop. I have tried "-loop 0", "-loop 1"  to ffmpeg and it has not helped. I have tried the same on ffplay as well and that has not helped either. Any help would be deeply appreciated.

Subject: [FFmpeg-user] Conversion from WMV to M2V - Lost Frame Problem
Message-ID: <SNT152-DS1A85668BD55555A4039BFB5880@phx.gbl>

I am converting a load of WMV files to M2V (i.e. video conversion only)
using the following basic command line:

 

ffmpeg -i input.wmv -codec:v mpeg2video -b:v 8000k -maxrate 10000k
output.m2v

 

However, it is imperative in my conversion that the number of frames in the
output file be identical to the input file.  However I consistently get one
less frame in the m2v files compared to the wmv files.

 

Is there an alternative command line that will ensure the total number of
frames is honored?

 

To provide a little further info, one example is as follows.  The input.wmv
file has 1037 frames, however the output m2v file only has 1036 frames:

 

D:\ffmpeg -i input.wmv -codec:v mpeg2video -b:v 8000k -maxrate 10000k
output.m2v

Subject: [FFmpeg-user] -longest rather than -shortest?
Message-ID: <07ef01d0036c$7e5a1ad0$7b0e5070$@webdimensions.org>

Hi, I am new to ffmpeg and I've been using it lately to create videos from
assembling images and mp3s.

I'm kind of stumped right now on something and I'm hoping someone in the
group can help me!

What I want to do is combine two mp3s into a soundtrack and combine them to
a video. I don't have any problem doing that, however, the issue is that no
matter what I try, the resulting video always stops at the end of the
shortest input track. This seems to happen whether or not I use the
-shortest argument.

What I want to do is find out how to make ffmpeg take the LONGEST piece of
media and make the video around that, and I have tried and tried and can't
seem to do it!

Can anyone help me?

Many thanks in advance. Sincerely,

Hugh

You can convert your sample with:
$ ffmpeg -flags2 +showall -i vid.h264 vid.mp4
(MPlayer always sets showall to speed up seeking.)

Before I open a ticket:
Could you elaborate how (exactly) you captured 
the stream? Is FFmpeg able to read frames 
directly from the camera? Or does this also 
need "-flags2 +showall"?

Thank you for the sample, Carl Eugen

Why do you think that the output file has 1036 frames?
The console output you provided suggests it has 1037 
frames.

Like for example, I want to say create a video with a 1 min background music
track, a 30 second voice over track. I can't figure out how to apply the
voice-over track to the longer background track without ffmpeg shortening
the output to 30 seconds - I want the entire 60 output with the background
music track even when the 30 second voice track stops.

Any ideas? Profuse thanks in advance

Subject: [FFmpeg-user] -longest rather than -shortest?

Hi, I am new to ffmpeg and I've been using it lately to create videos from
assembling images and mp3s.

I'm kind of stumped right now on something and I'm hoping someone in the
group can help me!

What I want to do is combine two mp3s into a soundtrack and combine them to
a video. I don't have any problem doing that, however, the issue is that no
matter what I try, the resulting video always stops at the end of the
shortest input track. This seems to happen whether or not I use the
-shortest argument.

What I want to do is find out how to make ffmpeg take the LONGEST piece of
media and make the video around that, and I have tried and tried and can't
seem to do it!

Can anyone help me?

Many thanks in advance. Sincerely,

Hugh

I have been inspecting the mpeg properties using the mpeg plug-in to
VirtualDub.  If I check the original wmv file it shows it as having 1037
frames and a length of 43.208.  If I convert the file using TMPGenc and
check it in VirtualDub it shows 1037 frames and a length of gives 43.208,
i.e. the same as the wmv file.  However, the output from ffmpeg shows in
VirtualDub as being 1036 frames and a length of 43.167 (the length is
1036/1037th of the original length).

So, it really does seem to be losing a frame in the conversion.

Andrew

Please run:
$ ffmpeg -i output.m2v -f null -
One of the last lines of the console output sill 
show you the actual number of frames in the m2v 
file.

If you don't believe the number the following 
command will output every single frame of your 
video as a raw mpeg2video file.
$ ffmpeg -i output.m2v -vcodec copy -f image2 raw%4d.m2v

The following will output a jpg for every 
single frame:
$ ffmpeg -i output.m2v out%4d.jpg

Please do not top-post here, Carl Eugen

Hi guys,

When i`m trying to send stream from ffmpeg to ffserver i have got

It`s not firewall problem.
Maybe linux distribution? Its Slackware..

Subject: [FFmpeg-user] ffplay does not seems to downmix 5.1ch audio to
	Stereo with "-ac 2"
Message-ID: <F12C2F96-CF3E-419C-B22C-01BD070F41D0@apost.plala.or.jp>

Hello list members, 

I'm trying to playback a mp4 video which contains 5.1ch audio with ffplay.  The mp4 file was made from DVD stream dump with mplayer, like the following ffmpeg command.  

$ ffmpeg -i /Volumes/USB\ HD\ 1/stream.dump \
> -map 0:0 -c:v libx264 -preset slow -level 4.1 -profile:v High -crf 18 \
> -map 0:2 -c:a libfdk_aac -filter:a volume=4.0 \
> -ss 00:17:29.500 -t 00:01:49.500 \
> test.mp4

To playback full audio of test.mp4 with ffplay, I need to use pan filter.

$ ffplay -i test.mp4 -af "pan=stereo|FL<FL+FC+BL+SL|FR<FR+FC+BR+SR"

If I use "-ac 2" with ffmpeg, that means downmix audio at the timing of encoding, ffplay playback full audio correctly.  


I don't know why this strange phenomenon occurs.  Can anyone help to solve the question?

I cannot reproduce this with a random sample here...
Do you see anything suspicious if you press "w" while 
playing to see a visualization?

> $ ffplay -i test.mp4 -ac 2

Please test the following:
$ ffplay -i test.mp4 -af aresample=ocl=stereo

Yes, the video would be lost.  pressing "w" one time, the video goes to black with white and purple oblique line. pressing "w" again, the video goes to complete black, pressing "w" one more time, the video comes back.  
Am I correctly describe the video state?

Nice!!  With above command, I can playback all audio correctly.  I'm happy aren't I?
So if I can playback audio with above ffplay command, don't I need to downmix audio at the timing of encoding?

Subject: [FFmpeg-user] error compressing Flash video
Message-ID: <546CD3DC.3040906@web.de>

Hi there,

I recorded an screencast in WinXP using the following command:

ffmpeg -f gdigrab -framerate 5 -i desktop -f dshow -i audio="Realtek HD
Audio Input" -vcodec libx264 -crf 0 -acodec pcm_s16le output.flv

It worked fine and I stopped it pressing Ctrl+C in the command-line window.

I tried to convert it, but I got an error:

Hello,
?? Reading about FFmpeg I saw that I can create a multiplexed transport stream with it. I am completely new to this environment and I tried to follow the guides that I found online but without success.?? May I please have a simple guide for a begginer user on how to install and create the multiplexed transport stream? I can have access to both windows and ubuntu.
?? Thank you in advance.
Kind regards,Thanos

I do not believe brew includes libfdk_aac support by default. As far as
I know you have to use:

  brew install ffmpeg --with-fdk-aac

Also see:

Simplest method is to download, extract, and execute a static build:

Linux: http://johnvansickle.com/ffmpeg/
Windows: http://ffmpeg.zeranoe.com/builds/

Hello,

there is a sample.
https://www.sendspace.com/file/leir3w

This happens only with this mts format (1440x1080, 50i) with my camera.
1920x1080 50p converts well (of course without the option interlace).

Regards,
Radek

Thanks of course I copied that off a discussion of bringing wma into iTunes.  Now I see the .m4a so it should work for mp3 through homebrew without an installation flag.  Cool.  The end use is actually to listen to these tracks on a wp8 phone ??.  But from a mac music gets to the phone from the iTunes library.

I do not believe brew includes libfdk_aac support by default. As far as
I know you have to use:

  brew install ffmpeg --with-fdk-aac

Subject: [FFmpeg-user] Codec "same" as opposed to "copy"?
Message-ID: <546D911C.3010403@burner.com>

I'm trying to do some audio channel processing, stripping off a bunch of
audio channels from an audio stream with 16 channels, taking the first 2
channels and turning them into 2 mono streams, dumping the remaining 14
channels:

ffmpeg -i manyaudio.mov -map 0:v -map 0:a -map 0:a \
  -codec:v copy -codec:a copy \
  -map_channel 0.1.0:0.1.0 -map_channel 0.1.1:0.2.0 \
  dualmono.mov

However when I use '-codec:a copy' it ignores my channel mapping and I
wind up with 2 x 16-channel streams.

My source's audio codec will typically be either pcm_s16le or pcm_s24le,
but ideally I don't want to care and want to say "use the same codec as
the source."  Is there a way to accomplish this that I'm missing, so I
don't have to probe the source file first to determine the codec in
order to specifically pass it along?

I only get a warning here with gcc 4.7 and gcc 4.9.1.
What does "g++ -v" show for you?

Yes, the channel mapping cannot work with -codec copy

I opened ticket #4124.
Work-around is to use "make V=1", copy the commands, remove 
-std=c99 and continue with make.

without trying to hijack the thread, sorry if i force it a bit but it is 
quite related:

is there a possibility (or is anything foreseen) in ffmpeg to 
*conditionally* copy the stream?
an example would be that in a batch process, i would only want to 
convert audio to aac if it is not already aac.
are there any workarounds on this other than first ffmpeg -i <source>, 
parse the output, try to detect what you have there and if it is not 
what you want convert, otherwise copy?
this workaround is reasonable for some sources, but for others where 
seeking is problematic or a large portion of the file must be read for 
detection it raises many problems.

Risking to repeat myself:
As soon as somebody sends a clean patch, why not?

Please don't forget that time is the only limiting 
factor for FFmpeg development.
(And I believe we have more important open bugs.)

Subject: [FFmpeg-user] ffmpeg profesional decoder compatibility mpegts
Message-ID: <1416491317633-4668216.post@n4.nabble.com>

Hi all, 

I'm using ffmpeg for a lot of tricks (mainly for encoding) BUT i can't use
professional decoders (Ateme, Ericsson, Tandberg, etc...) to decoding my
stream (udp or rtp over mpeg2ts). 

Do you know why ? 
The stream is really good decoding by any avconv/ffmpeg player or vlc or
raspberry or whatever BUT NOT by professional decoders. 
They "see" the stream (they probe it) but they can't decode it and show the
service, pid program, video and audio. 

I did this : 

avconv -i udp://@:5006 -map 0  -codec copy -streamid 0:512 -streamid 1:4112
-metadata:s:a:0 language=eng -metadata service_name=test  -metadata
service_provider=test2 -mpegts_service_id 0x1  -f mpegts
udp://192.168.1.54:5004?pkt_size=1316?ttl=8

Thanks,

This looks like an intentionally broken version 
of FFmpeg that contains several hundred known 
bugs not present in FFmpeg, some of the security 
relevant. Please understand that we cannot 
support it here.

On ffmpeg mailing list people would like to know, what command you used
by ffmpeg
not avconv.

Complete uncut ffmpeg console output is what any one want to provide any
info.

from avconv command it looks like you have some encoder installed on
your PC, which is
providing stream, check whether bare output of encoder of each stream is
decodable by
its refrence decoder, FFmpeg is very stable code, to give user maximum
out of video.
It supress some warning, may be debug log from FFmpeg would be helpful
to you.

Sorry for avconv but also with ffmpeg it's not working

ffmpeg -i udp://@:5006  -vcodec copy -acodec copy -streamid 0:512 -streamid
1:4112 -metadata:s:a:0 language=eng -metadata service_name=test1  -metadata
service_provider=test2 -mpegts_service_id 0x1  -f mpegts
udp://192.168.1.54:5004?pkt_size=1316?ttl=8

Thanks,

This looks like an intentionally broken version of 
FFmpeg that contains several hundred known bugs not 
present in FFmpeg, some of them security relevant, 
please understand that we cannot support it here.
Please see http://ffmpeg.org/download.html for 
supported versions, please test *current git head* 
before reporting problems here.

See http://blog.pkh.me/p/13-the-ffmpeg-libav-situation.html 
for more information about the fraud that hit you.

No, this is *not* an old FFmpeg version, such a 
version has never existed.

Then please try with the movie filter as input, 
there is no loop option for files passed via "-i".

Though I am not sure, from long time I was not here, Most of the times
things printed on console is known as Console Output of ffmpeg. Use git
version and your console output would look like as console output.

you can download snapshot from here
https://www.ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2

As u are vey new user here, I would suggest
scroll through following links.
https://www.ffmpeg.org/download.html
https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu.


If your problem still persist, then come again.

I dont see any problem in ffmpeg, you r not using ffmpeg codecs
to encode either video or audio. so if the generated video does not work on
any professional  decoder then there is problem in Encoder of Input
provider.

Thanks
Anshul

i'm agree but the encoder used is a professional one (same brand as the
decoder), Ateme. 

When i stream directly from the Ateme encoder to the Ateme decoder, it
works. 
When i stream from the Ateme encoder through ffmpeg and ffmpeg streaming to
the decoder, it's not working. 

What i don't understand is why it's not working ?
because professional equipment are only working with professional equipment
? 

i'm sure we can do the trick, i'm sure of that
maybe it's just something about the PCR pid or program pid or whatever 

i'm also compiling ffmpeg with the tutorial
https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu and i will try in few
minutes

Does it work if you don't use -codec copy but if 
you encode to mpeg2video or libx264?
Did you already try audio-only or video-only?

Message-ID: <CAMM8HvW3VHhTF1vmS262QeYtMeYjd8B-s_nMFeKfHi+qsYGJaw@mail.gmail.com>

Hello ,

I am receiving H264 encoded video over a tcp socket , the decoder that I
have works only on a complete frame .
can I use ffmpeg to extract a complete frame from the received H264 data ?

This is the default, you can only extract complete

I had another look at this today and managed to find a solution.

Adding "-bsf:v dump_extra" makes the mpeg2ts output file readable by ffmpeg.

Hi,

Please help with the following issue:

I have audio breaks when playing LiveTV stream that seems to use AC3-Dolby
digital audio format. My ffmpeg library is the 2.4.3. The application is
XBMC (under OpenElec 3.2).

Behaviour: There are constant breaks in audio when playing the stream. The
synchronization between audio/video is fine.

When checking the log of the application, I got this:

Did you do this?
As an alternative, please provide a download link 
here on the mailing list.

> Already check: ffmpeg library 2.4.3 is the latest up to 21/11/14.

No, the latest is f0ae0354, if you think our download 
page does not explain this well, please tell us!

Message-ID: <FF2720C1-45C0-454B-BB59-D52345E06BCE@apost.plala.or.jp>

Hello list members, 

I know that SDL can be build without X11 on Mac OS X.  Without X11, ffplay works fine on Mac OS X.  
My question is that ffplay should be build with X11 or should be build without X11 on Mac OS X.  Is there any recommendation?

Thanks for help!!

As per your suggestion tried the below, unfortunately did not work....any other suggestions? Should the base video be a movie filter instead of nullsrc?

Then please try with the movie filter as input, there is no loop option for files passed via "-i".

Subject: [FFmpeg-user] Audio and Video Out of Sync with UPD stream input and
	flv RTMP output
Message-ID: <CAOTh+LNmA132AYOMM6HVQ9DLzOcMjorzzFTYFJ8kiYXwTpi0+A@mail.gmail.com>

Hello everyone,


I have troubles with A/V sync for a live RTMP output stream generated by
ffmpeg. After playing around with the parameters for a few days now, I
still wasn?t able to get rid of the sync issues. I hope that you could spot
an issue in my command or advise me in how to avoid sync troubles. I would
extremely appreciate any help here.

Here?s the my problem: In order to publish a live RTMP stream, I use one
UDP input, this is coming from an application that is only able to output
raw formats.  Ffmpeg is used for encoding  resizing and encoding video to
H.264. Finally, streams are muxed into flv and published via RTMP. In
general, this works very well, and the results look great. However,
unfortunately A/V seems to drift after running for a couple of days or 5-6
hours.

Here?s the my command:

sudo ffmpeg -y -f rawvideo mpegts \

-fflags nobuffer \

-i 'udp://@UPD LINK?fifo_size=1000000&overrun_nonfatal=1' \

-maxrate 4000k -bufsize 4000k \

-af volume=1.0 \

-strict experimental \

-c:a libfaac -ar 44100 -ac 2 -b:a 128k \

-vsync 1 -c:v libx264 -r 25 -vf yadif,scale=720:576 -aspect:v 16:9 -b:v
4000k -pix_fmt yuv420p \

-preset superfast -tune zerolatency -threads 0 -crf 25 \

-fflags nobuffer \

-f flv 'rtmp://[URL]'

I have tried several vsync settings and ?map? variations. I believe the
above command should try to sync the video stream to the audio stream,
which seems most sensible for our scenario. I have tried it the other
around as well, with no different results, i.e. A/V is still drifting.

As I am able to confirm that the source application feeds very well.  Also
i have changed output rtmp to hls but result was same still drifting.

In case of problem i checking source by dumping video and saw that there is
no problem.

I am break current connection and reconnect to same udp link then problem
was solving but i can do this everytime.

Here is my questions what is the source of problem and how can i understand
video and audio out of sync. I am thinking if i can undestand drift between
audio and video then i can reset the connection and then reconnect the
source.



This is console output,

If you're trying to use that with
-i audio="Microphone"
You may want to try
-i audio="Realtek HD Audio Input"
instead.

Unfortunately there's no easy "fix" unless someone were to implement the
"PrintWindow" API.
Patches welcome, for sure.

Subject: [FFmpeg-user] ffmpeg exits before streaming
Message-ID: <CACS_vg=mExGSvjC5dG+fiUahViCqy_1jfcpXmYVUQzxMJJkNUQ@mail.gmail.com>

I'm trying to combine a music file, /persist/01.m4a with video,
/persist/bars2.mp4 and stream it to ffserver.

the following command works:

ffmpeg -loglevel debug -i /persist/01.m4a -i /persist/bars2.mp4 -pix_fmt
yuv420p -c:v libx264 -c:a libfdk_aac -s 320x240 -f flv /persist/test.flv


the following command exits seemingly before anything is streamed:

ffmpeg -loglevel debug -i /persist/01.m4a -i /persist/bars2.mp4 -pix_fmt
yuv420p -c:v libx264 -c:a libfdk_aac -s 320x240 -f flv

Using the command that saves to disk, the process takes several minutes.
When I attempt to stream, ffmpeg seems like it doesn't do anything, it just
skips doing what I asked it to do and exits. Lots of "skip"s everywhere.
I'm assuming the "side data" is the problem. Also there's that h264 saying,
"no picture" which might be the problem.

My questions...

What does "skip 2112 samples due to side data" mean? What is side data? Is
there a way I can fix the skipping?

Subject: [FFmpeg-user] config error
Message-ID: <CAKt_7i9SccgGeo+VnJXoB9+2HdjpwcWHUMEbOZUwt+c1ovok9Q@mail.gmail.com>

Hello,

I've tried to install the latest ffmpeg on ubuntu 14.04. The configuration
didn't go so well. In summary, I tried to configure and yasm was a problem,
so I tried the crippled build(no idea what that is). Then when I try to
make, I get an error. I've copied the terminal out put here:


hugh at Dat-Pad:~/Documents/ffmpeg-2.4.3$
PKG_CONFIG_PATH=/tmp/ffmpeg/lib/pkgconfig ./configure
yasm/nasm not found or too old. Use --disable-yasm for a crippled build.

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
solve the problem.

the happiest solution would be that you simply do not have libfdk_aac
but DO have an alternative aac codec
try a

 ffmpeg -codecs | grep aac

and see what aac codecs you have

Subject: [FFmpeg-user] Accurate Seeking without Re-encoding
Message-ID: <CAH57R-OQxN9Js2RoKnG97tXC_U-6xk0vK7HWet6fVb9mrB8Y-Q@mail.gmail.com>

Hello,

I'm trying to accurately (not just nearest keyframe) cut out a subtrack of
an mp4 without having to re-encode the *entire* subtrack.

It seems like overkill to re-encode everything just to get a few additional
seconds of accuracy at the beginning.  Is there a good way to avoid this?
I'm perfectly happy to re-encode a bit of the subtrack, I just don't want
to have to re-encode everything.

My current thought was to re-encode from an accurate start point to the
next keyframe, then copy from the keyframe to the end of the subtrack, and
then concatenate the pieces using the concat demuxer.  Is this a reasonable
approach, or is there a better way to go about things?

I can get the pieces of the mp4 to start and stop at the right times, but
so far I haven't been able to get the concat demuxer to work on one
re-encoded mp4 and one stream copied mp4.  I'm not exactly sure what has to
match between the re-encoded piece and the copied piece.

I'd like the final output to be an mp4.

Thanks in advance!

Subject: [FFmpeg-user] duration problem of concatenated audio in powerpoint
Message-ID: <201411241912178814793@gmail.com>

Hi all,

I'm using ffmpeg to concatenate some mp3 audios. 
There is no problem when playing the concatenated audio with VLC and WMP. 
But if I inserted them into PPT files with Microsoft PowerPoint, the duration displayed in powerpoint is smaller than actual duration. And the player stopped very early (at position ~70%) if I playing them in fullscreen mode in powerpoint. 

Here is the minimal example code: 

[root at localhost audio-concatenate]# ll 
total 24 
-rw-r--r-- 1 root root 19688 Nov 24 11:19 a.mp3 
drwxr-xr-x 3 root root 4096 Nov 18 11:37 mp3

Subject: [FFmpeg-user] Worse quality than mencoder
Message-ID: <m9.2lWLN.1Bkrpu{f5Eh.1KSpoi@seznam.cz>

Hi all,

I used these commands to encode my videos:

for pass in 1 2; do
? mencoder -oac mp3lame -lameopts cbr:br=128 -ovc x264 -x264encopts pass=$
pass:preset=veryslow:fast_pskip=0:tune=film:frameref=15:bitrate=1000 -o out.
avi in.avi
done

I wanted to change to ffmpeg because of troubles with A/V sync, so I encoded
by these commands:

for pass in 1 2; do
? ffmpeg -y -i in.avi -c:a libmp3lame -b:a 128k -c:v libx264 -b:v 1000k -
minrate:v 1000k -maxrate:v 1000k -bufsize 1835k -pass $pass -preset veryslow
-tune film -x264-params fast_pskip=0:frameref=15 out.avi
done

But I didn't get the same quality, I had to add 15 % to bitrate to get the 
same visual quality.

Is there any parameter which is set in mencoder but not in ffmpeg? I tried 
to set a dozen of parameters in ffmpeg to the defaults of mencoder but 
haven't found the responsible option.

Thank you in advance for any advice,
Jan Sever

You are setting VBV options for ffmpeg and not in mencoder (and forcing
CBR at that) do I'm not surprised you get different output.

If you mean "-b:v 1000k", ffmpeg doesn't allow me to run 2-pass without it. 
Is there another way to get CBR with ffmpeg?

P. S. Thanks for your very quick answer.

Why do you want CBR?  I don't think mencoder is giving you CBR.

I did not mean that bitrate but the maxrate and bufsize you have given.

that's not the problem *but* you set the 1000k on more places and so 
force CBR instead VBR which is bad, especially in context of 2-pass 
because that can *heavily* benefit of VBR in both directions for a 
optimized balance quality/size

Mainly because of network throughput. Mencoder can make it pretty well.




"I did not mean that bitrate but the maxrate and bufsize you have given."
I tried to encode it without maxrate and the result was unfortunately worse.

Omitting maxrate gave me worse results.

Do not use --disable-yasm unless you want a slow, 
unsupported output. yasm is a small, selfcontained 
binary, compile it yourself and put it somewhere in 
your patch (no need to "make install" if you don't 
want to).

Remove your current working directory and check 
out again. (Do not use sudo or su when building 
FFmpeg.)

Does it work if you try to compile hello world for Android?

Subject: [FFmpeg-user] Mixing two audio files to left/right channels,
 but using a (stream-copied) video from a third input
Message-ID: <CAFqA6+XK_48LAxDn6UAjwi3Me4+KLoW7VsX=qMNyBSPBdj28fA@mail.gmail.com>

Hello everyone,

and sorry if the title is convoluted, I couldn't find a better one. What
I'm trying to accomplish is simple, in practice: Assume I have three files:
- Left_Audio.mp3
- Right_Audio.mp3
- Video.mov

(Extensions are not important). What I would like to achieve is to come up
with a CLI command which would give me a resulting video such that:

- The left audio channel of the output will be mixed from  Left_Audio.mp3
- The right audio channel of the output will be mixed from Right_Audio.mp3
- The video will be a stream copy of Video.mov

To be even clearer, I guess what I need is something along the lines of
what's described here (covers exactly my audio needs) but with the extra
step of the video copy:

https://trac.ffmpeg.org/wiki/AudioChannelManipulation#a2stereostereo

(last picture of the section, where we send FL and FR of input 0 to FL of
output 0 and so on and so forth.

If what I'm looking for is not possible with a single pass, I would also
accept a simplification:
- Generate the audio mix, produce an intermediate file and then create a
new output obtained with the resulting audio mix plus the aforementioned
stream copy of the video.

Is that possible?
Thanks in advance!

Since there is no info (ffmpeg console output) about your inputs I'll
assume your audio inputs are both stereo, and that you only want the
video stream from Video.mov while ignoring any other stream types:

ffmpeg -i Left_Audio.mp3 -i Right_Audio.mp3 -i Video.mov \
-filter_complex "[0:a][1:a]amerge,pan=stereo|c0<c0+c1|c1<c2+c3[aout]" \
-map 2:v -map "[aout]" -c:v copy -shortest output

I think this is not the source of the problem: I saw the same bitrate in the 
time of frame which I visually compared; so there should be another different 
option. Do you please know what?

Message-ID: <5A651CA75E25F940A89A85F2A41F388D8C2C6C@EXCHANGE-DB2.msdtech.net>

Hello all,

I am attempting to take an rtmp stream and push it out over multicast.  It appears like it is working on the server end and I can see the packets pushed out; however the video does not play in any player.  If I run wireshark on the receiving machine I can see the rtp packets arriving; however the video player (ffplay, vlc, or quicktime) just sits as though it were waiting for data.  No players give an error, they just go into what appears to be a ready state.  Any thoughts on what is causing this or what I could do to further troubleshoot?

You are exactly right Lou, that were my assumptions.
Thank you very much for the help and the ready-to-use video filter!

Many thanks,

You could check if the ffmpeg and mencoder file sizes match to see if your assumption is true.

Yes, the size is almost the same (+/- 0.2 %).

OK, I removed it, but I still cannot get the same quality. Do you know about any parameter which could cause it? As I've said the problem disappears when I raise the bitrate by 10-15 %.

Hello guys,

When i`m trying to send stream from ffmpeg to ffserver over HTTP i have 
Connection reset by peer error.

When i`m sending via udp to server where ffserver is (external IP), i 
don`t have any error

(Maybe anyone can share own ffserver feed for while for tests, i will 
try to send my stream?)

Full debug bellow, i wll be v. glad for help. Maybe anyone can share for 
some while own ffserver for test.

discussed here:

http://lists.mplayerhq.hu/pipermail/ffmpeg-user/2014-October/023982.html

those settings aren't exposed by any programs other than mediainfo, but
you can also see that embedded info doing something like this:

$ strings < out.avi | grep -E "x264.*core"

You should at least compare the settings from mencoder and ffmpeg (and
share the output here), as you/we might get an indicator as to which
setting is leading to bad results.

I also haven't seen the full uncut console output of either encoding command
yet, please do provide. Just in case. :-)

You read my thoughts: I just wanted to ask how I could get the parameters 
from mencoder (ffmpeg has it on its output). I should have known that it's 
as easy as plain text in the files.

The output is surprisingly the same:

It's very long, especially from mencoder, so I dropped some insignificant 
lines (marked as {more times}), which are similar to previous, so hopefully 
nobody feels flooded; and changed \r to \n to read it easier.

Subject: [FFmpeg-user] Problem with instances of ffplay
Message-ID: <CAF4t7ANy4GAM0AUjRu+06+3tFjD0xAa=QCkghmmd=ZGh4oXRRQ@mail.gmail.com>

Hello everyone,

I'm not sure whether this problems relates to ffplay, ffmpeg or my system's
OS. I would appreciate any kind of comment, suggestion or solution.

here is the scenario:
I use ffmpeg to stream video files to UDP and then I use ffplay to play
these streams (all on the same machine using ffmpeg -re -i input1 -f mpegts
udp://localhost:port1 and ffplay udp://localhost:port1 and similar commands
for other streams). I first run the ffplay commands and they seem to be
waiting (or listening) to udp port for incoming streams, then I start
streaming with ffmpeg. This works fine in most of the cases and if I have
for example two streams of video then two instances of ffplay will start
playing these videos in separate windows right after the streaming starts.

The problem arises in some cases when I start ffmpeg streams shortly one
after another then the system does not open two separate instances of
ffplay in separate windows, instead both video streams get merged and
played in one ffplay instance and in one window. Although I dedicate two
different ports for each stream, but one of the players seems to be still
on the waiting mode showing the following in the console while the other
one plays both streams.
 nan    :  0.000 fd=   0 aq=    0KB vq=    0KB sq=    0B f=0/0

This problem appears more frequently when instantiations are somehow
automated (e.g. using bash). But also appears when I switch between console
tabs rapidly and run ffmpeg instances. What do you think about this? Is it
related to streaming with ffmpeg? or ffplay binding to udp ports? or OS's
inabilities to dedicate resources for each instance of ffplay? How can I
track it down and narrow this scope?

My ffmpeg version: ffmpeg version 2.3.git. Does it need upgrade? I was
simply waiting for 2.5 to be released.
OS: Ubuntu 14.04 LTS

Thanks a lot,
Maziar

I don't think ffmpeg have parameter for srt or ass styling.  (If my thought is incorrect, please let me know, experts)

In my thought, srt does not have style information.  If you want to use srt with styling, you have to provide a srt.style file.  But I don't know ffmpeg can handle srt.style file with srt file.

Another thought, ass subtitle can handle styling information in it's file.  You can convert srt subtitle into ass subtitle with the following command.  

$ ffmpeg -i subtitle.srt subtitle.ass

After conversion, you can add any styling information into ass file using your favorite text editor.

No problem, that's fine.

You're doing two-pass, right? If that is why these logs each contain
two outputs from the encoders, then you're doing something
significantly wrong:

mencoder.txt:x264 [info]: profile Main, level 3.0
mencoder.txt:x264 [info]: profile High, level 4.0
ffmpeg.txt:[libx264 @ 0x63c9c0] profile Main, level 4.0
ffmpeg.txt:[libx264 @ 0x63c9c0] profile High, level 4.0

The libx264 settings from the first pass and second pass differ
significantly from each other - and in a different manner in ffmpeg and
mencoder. Only the second pass settings seem identical, which may be
why you see the same embedded in the file.

AFAIU you need to use identical codec options in both passes, and it
seems you're not doing that. That _may_ be the cause for your
observations.

I'm sorry, they're the same only for the second pass: that was the problem.

Level was not the problem.

Yes, you're right, that was the problem. The encoders set some parameters
for quicker first pass (I knew that), but what I didn't know that ffmpeg doesn't
set fast_pskip=1 and ref=1 while mencoder does.

In fact, it is. I compared the achieved quality after changing the two mentioned
parameters and it looks almost the same now. So marking as SOLVED. Thanks
everybody for your precious help.

I wasn't aware of that, but didn't actually find any source indicating
to having to use the same parameters either (which is why I added
"AFAIU").

Excellent, thanks for letting us know. My guesswork actually provided
some value. :-)

 Hi,


 with the latest versions of ffmpeg converting a SONY AVC100CBG_1920_1080_H422IP at L41 to Quicktime Movie the
 resulting movie plays but display remains green in the quicktime player, both mplayer and ffplay will play
 the resulting mov.
 
 The same command tested with ffmbc-7.1 works fine.

Subject: [FFmpeg-user] Relevant image degradation after 6-8 hour of encoding
Message-ID: <CAHss8oEM0ZWRmm1xUOdYSUTg9NEj1HONt-29fRNUX_7X5aEC6A@mail.gmail.com>

Hello,
I'm trying to transcode a live stream and I faced the issue in object.
Picture looks much more "pixellated" especially on I-frames, giving the
video a "pulsing" effect.
I've attached a screenshot of image quality after ~1h and after ~8h.

My test stream was a single video in loop.

This is the command line I used:

ffmpeg -probesize 20M -channel_layout stereo -i <any_stream> -vcodec
mpeg2video -pix_fmt yuv420p  -aspect 16:9 -b:v 1200k -minrate 1200k
-maxrate 1200k -trellis 2 -g 24 -bf 2 -acodec mp2 -ac 2 -ar 48000 -b:a 128k
 -streamid 0:70 -streamid 1:71  -f mpegts -flush_packets 0 udp://

Of course it's unable, because:

So this must be wrong:

This is not the latest version;-(


Just to be sure I checked today with a fresh build(s) from git and did some tests
to see if i could come up with some more relevant information.

ffmpeg -i AVC100CBG_1920_1080_H422IP at L41.MXF -map 0:0 -map 0:1 -map 0:2 -c copy -vtag ai12 FFMPEG.MOV

ffmpeg version N-68057-g92fa1d9 Copyright (c) 2000-2014 the FFmpeg developers
  built on Nov 27 2014 19:29:47 with Apple LLVM version 6.0 (clang-600.0.54) (based on LLVM 3.5svn)
  configuration: --arch=x86_64

  libavutil      54. 15.100 / 54. 15.100
  libavcodec     56. 13.100 / 56. 13.100
  libavformat    56. 15.100 / 56. 15.100
  libavdevice    56.  3.100 / 56.  3.100
  libavfilter     5.  2.103 /  5.  2.103
  libswscale      3.  1.101 /  3.  1.101
  libswresample   1.  1.100 /  1.  1.100

 The resulting file is now playing fine. When building with my standard config

configuration: --arch=x86_64 --enable-libmp3lame --enable-libfaac --enable-libvpx
--enable-libx264 --enable-libx265 --enable-libopenjpeg --enable-gpl --enable-nonfree
--enable-pthreads --enable-avfilter --enable-libfreetype --enable-libass --enable-shared


The greenscreen when playingback in the quicktimeplayer has returned so is it safe to say
that its related to one of the external library's ? 

Tested with a static build found on the internet

Converted to mov with the same command

ffmpeg -i AVC100CBG_1920_1080_H422IP at L41.MXF -map 0:0 -map 0:1 -map 0:2 -c copy -vtag ai12 FFMPEG.MOV

This config give's the green screen when playing in the Quicktimeplayer, mplayer is fine.


For final test I build with

ffmpeg version N-68057-g92fa1d9 Copyright (c) 2000-2014 the FFmpeg developers
  built on Nov 27 2014 19:54:47 with Apple LLVM version 6.0 (clang-600.0.54) (based on LLVM 3.5svn)
  configuration: --arch=x86_64 --enable-libx264 --enable-gpl --enable-nonfree
  libavutil      54. 15.100 / 54. 15.100
  libavcodec     56. 13.100 / 56. 13.100
  libavformat    56. 15.100 / 56. 15.100
  libavdevice    56.  3.100 / 56.  3.100
  libavfilter     5.  2.103 /  5.  2.103
  libswscale      3.  1.101 /  3.  1.101
  libswresample   1.  1.100 /  1.  1.100
  libpostproc    53.  3.100 / 53.  3.100

Now the resulting mov file plays fine.

When converting there is a difference in printout for the working version

Subject: [FFmpeg-user] H.264 Quicktime encoded file stutters
Message-ID: <CAMGzDuNG-RSHt0BjmiVRuFmMG_8sh6tJkYxMonORmnNxsMb_rg@mail.gmail.com>

Hello everyone,

I am still quite new to ffmpeg, but I'm already using it to convert some
content - mostly to Quicktime format.

During one of these attempts, I wanted to convert a JPEG2000 MXF file from
a DCP into Quicktime file with H.264 codec, that would mimic the same
experience as if the file would be encoded with Quicktime player itself (or
maybe Compressor).

At the end, this Quicktime file would be played using a windows PC with the
Quicktime Player, so my goal was to create the exact same experience.

I created a small sample from Quicktime player and then compared it to the
same file created using ffmpeg. At first, I was able to adjust all settings
in ffmpeg (CAVLC, ref frames, b-frames, resolution, bitrate, etc) to mimic
all configurations used by the H.264 file created by Quicktime player.

The info was provided by Mediainfo, and although not all parameters for
H.264 were there, the ffmpeg generated file seemed to equalize all settings.

Unfortunately, when played in Quicktime player, the final ffmpeg H.264 file
would stutter. The original movie frame rate had 24fps, and Quicktime would
play only 16fps on average.

This is the command line I am currently using:

ffmpeg -r 24 -i Input.mxf -vf "scale=1920:1038,pad=1920:1080:0:21" -pix_fmt
yuv420p -c:v libx264 -r 24 -profile:v main -level 4.1 -preset faster -coder
0 -crf 21 -x264opts keyint=60:bframes=1:ref=2:qpmin=4:b-pyramid=0 Output.mov

And this is the console output:

After some more testing, it seems to me that the problem does not lie in
H.264 encoding, but in Quicktime container itself.

I made another test, and encoded the MXF into Quicktime ProRes, which
played fine in Quicktime Player. No stutter, no issues, it was ok.

Then, I grabbed this ffmpeg-ProRes file and fed it to Compressor in order
to create a final H.264 file. The resulting file ended up having a stutter
just like the original  H.264 ffmpeg file.

When played side by side, the H.264 file from ffmpeg and the H.264 file
from ffmpeg>compressor seemed very similar. The main difference was that
the original H.264 ffmpeg file had all frames (i.e. when moving frame by
frame in Quicktime player, it was possible to see that all frames were
indeed in the file), and the H.264 file converted by Compressor had
duplicated frames that indeed caused the stutter effect when played.

So there may be something or some timebase in the final Quicktime container
that my get messed up in Apple software and/or workflow (the "tbn"
perhaps?).

No, this configuration: --arch=x86_64 --enable-libx264 --enable-gpl --enable-nonfree
works

Thought I'd have a go at this, but suffered an odd epic fail.

x265 builds and installs fine, and the standalone at least responds to
x265 -h.

there are the expected:-
/usr/local/lib64/x265.a
/usr/local/lib64/pkgconfig/x265.pc
/usr/local/include/x265.h
/usr/local/include/x265_config.h

however ./configure reports:-
"ERROR: x265 not found"

This is a lie as the end of config log shows it is found, but throws up
lots of "undefined reference to " errors:-

thanks Carl, not sure if it will work for me, as I am trying to make a
static build and the above thread has made me realise I am missing the
glibcpp static libraries, only having the glibc ones... but at least I
now understand why it was such an epic fail....

my problem is after exporting from Adobe Premiere and postwork with ffmpeg
I get more frames of each mp4-footage. I minimalized it to the following
example:

I exported 2:00.0 min of black-screen from Adobe Premiere and after
encoding it through ffmpeg like

:\>ffmpeg.exe -y  -i before.mp4 after.mp4

it has 4 frames more (in Adobe Premiere only 1 see screenshot).
When I make

:\>ffmpeg.exe -y  -i before.mp4 -c copy after.mp4

everything is fine. Somethng happens with the encoder?

What I saw - but don't know wht it means is:

before.mp4 : yuv420p(tv)
after.mp4   : yuv420p

Ouptut for before.mp4 (Adobe Premiere export)

When i rewrap using -vtag aivx

ffmpeg -i AVC100CBG_1920_1080_H422IP.MXF -map 0:0 -map 0:1 -map 0:2 -c copy -vtag aivx FFMPEG.MOV

Then Quicktime ( only tested with 7 ) can't play the file, furter more FCPX-10.1.3 uses the same
vtag ai12 when rewrapping this to an original AVC-Intra format in mov.

The logic I found checking what FCPX uses to rewrap to mov but not
completly tested all possible combinations

- ai12 is used for HD 25, 29,97
- ai13 is used for HD 23.98 

- aivx is used for 4K formats


If i use -vtag aivx in ffmpeg then playing in Quicktime won't work but cmd-I shows the correct info
but the player window remains green. Mplayer will playback video.

FFmbc refuses to use -vtag aivx but when using -vtag ai12 produces a 4K file that plays in quicktime
the cmd-I info is not consistend with the video as would be expected ( wrong frame rate).
Trying same thing in FFMPEG but this won't work for an AVC_4096_2160_H422IP at L52 50FPS file.

A AVC_4096_2160_H422IP at L51 25FPS -vtag ai12 plays when rewrapped bij FFMBC and FFMPEG in Quicktime-7,
Quicktime PlayerX prompts an error " operation could not be completed ".

There are a lot more options to investigate but the initial conclusion is that everything above HD frame
size has problems in just rewrapping to quickitme mov. FFmbc-7.1 seems to produce a more tolerant
version but is not prefect either.

Om my test system i have FCPX installed and the Sony XAVC plugin.

Any Suggestion to get this fixed are more then welcome.

Maybe I should refrase this to 

" The latest version from git this afternoon works fine for HD "

If you read my previous posting there are still a number of issues
with rewrapping 4K XAVC MXF content to quicktime MOV that would be nice
if they could be resolved in the future.

If these are bugs or not implemented at this time is for me as user
difficult to determin.

Thanks for quick response.

Subject: [FFmpeg-user] Error with parameterization using h264 with profiles
Message-ID: <547886BC.9060506@dimis.fim.uni-passau.de>

Hi everybody!

I'm struggling with a simple task. Converting an .avi containing a 
single cvid
video stream with rgb24 color model to a .mp4 with h264 encoding.

For some reason, ffmpeg won't let me use any other h264 profile other than
high444. With every other profile i use, the encoder still seems to use 
yuv444p
pixel format (which is only allowed in high444). Doing so /
  ffmpeg -i input.avi -vcodec libx264 -vprofile main -pix_fmt yuv420p 
out.mp4/
results in an error:

Output #0, mp4, to 'out.mp4':
     Stream #0:0: Video: h264, yuv444p, 320x240, q=-1--1, 90k tbn, 15 tbc
Stream mapping:
   Stream #0:0 -> #0:0 (cinepak -> libx264)
/Error while opening encoder for output stream #0:0 - maybe incorrect
parameters such as bit_rate, rate, width o//r height/

I can circumvent the problem by manually specifying the correct pixel 
format:
/ffmpeg -i input.avi -vcodec libx264 -vprofile main -pix_fmt yuv420p 
out.mp4/

Is this an intended behavior? For what I read in the documentation, I 
expected
ffmpeg to automatically choose parameters in accordance to the selected 
profile.
Or is the profile selection more like an assert, just telling me 
whenever I'm not
in accordance with the constraints of a selected profile?

Thank you for any information on this topic!

Hello,

I need to put custom http headers into my ffserver output stream. In ffmpeg you would do it with the -headers command. Is it possible to achieve this in ffserver?
I particularly need to set "Transfer-Encoding: chunked", "Content-Length:0" and "AcceptRanges:none"
Help would be much appreciated

Hello,

Is it possible to set min_port and max_port for rtsp udp streaming in the ffserver config file?
Because the default range of 5000-65000 won't work for me because of firewall restrictions. But I need to do udp streaming and not tcp

Thanks for any help I can get

no mediaplayer on this planet will play a http://youtube.com/xxxxxx URL 
which is just a *website* and not a videofile

you need a way to parse that HTML page, follow all sort of links and 
embeds and finally get the URL of the video itself

I believe it should work with FFplay if compiled 
with --enable-libquvi.

If your build supports libquvi then you may be able to just do:

ffplay http://www.youtube.com/watch?v=xxxxxx

However I haven't tried it myself.

Note: I'm curious about the outcome of this nowadays since libquvi seems
discontinued. We might want to check if youtube-dl provides a maintained
alternative.

Subject: [FFmpeg-user] bug in zoompan with overlay filters ?
Message-ID: <CAFTMgbe-j42ueEeY8QKr1WuWtpX2zVNwL1FmnXZLY-zvq-UjNQ@mail.gmail.com>

Hello,

It seems there is a bug in zoompan.
If we use an overlay filter on the output of zoompan, the zoom progress
stops at 2 seconds whatever the 'd' parameter of the zoompan.
If we remove the overlay fliter, it works.

Here is the command;

ffmpeg -loglevel info -y  -f lavfi -r 25 -i color=black  -loop 1 -r 25 -i
pic.png -filter_complex " \
 [0:v]scale=640x480[background];  [\
 1:v]scale=640x480,zoompan=z='zoom+0.001':x='ow/2':y='oh/2':s=640x480:d=250,setpts=PTS-STARTPTS+1/TB
[vshot2]; \
 [background][vshot2] overlay[vfinal]" \
 -strict -2 -c:v h264 -b:a 96k -aspect 640/480 -pix_fmt yuv420p -t 10 -map
[vfinal] final.mp4
