I read that it was "less synchronous"

tested it myself.

Did you get them before?
I have been contemplating a patch to ffmpeg to make the directshow
input "back off" by not accepting more packets instead of just
dropping them on the floor.  It's a more 'direct-show-y' approach but
haven't done it yet, nor am I indeed certain if it would be better or
not.  Until then, you can either limit the fps of your input, or live
with the "frame dropped!" messages I guess.

Anyone know why the movie doesn't play?

Subject: [FFmpeg-user] ordering of default codec?
Message-ID: <CAL1QdWd8wc5tQ5wU2iy_0av1Vpghpf96PPS+Y_wUiKANL5vQBg@mail.gmail.com>

I've noticed that ffmpeg puts codec "priority" (if you can call it
that) in a slightly different order than I'd like it.
for instance
$ ffmpeg -i yo.mpg -c:v libx264 -an nul.mp4

encodes by default to aac.
If I have both libfaac and libfdk-aac, it chooses the "default" as
libfaac, even though it seems to me like libfdk-aac would be higher
quality, and so should be "chosen first."
I don't think that changing their ordering on the configure line helps.
Anybody else have any information they could share with me on this? Or
is a patch that "orders default codecs more by quality" something I
should try and come up with?
Cheers!
And go Michael Phelps.

Subject: [FFmpeg-user] Translating working command line to programmatic code
Message-ID: <37926CFC-51ED-4851-B18A-6B0C7FB97130@bighillsoftware.com>

Hello, 

*** My use case: 
On a Mac, I need to capture video from an attached camera (such as the internal MacBook Pro camera), transcode it to FLV, and then stream (publish) it to Wowza media server for restreaming. 

*** What I have done so far: 
I have successfully used the ffmpeg client to take an mp4 video, transcode it to FLV, and publish it to Wowza using RTMP, using the following command line: 

ffmpeg -i ~/SampleVideo.mp4 -re -r 24 -b:v 1000k -f flv rtmp://localhost/live/SAMPLE_STREAM

I have also consumed the video from a web browser successfully, so I know that this is both possible in ffmpeg and works. Basically the above serves as a successful prototype for my use-case. 

*** What I need to do now: 
I need know how to do two things specifically: 

1) Convert the above command line to programmatic code which uses the underlying ffmpeg libraries to accomplish the same thing. Can anyone point me in the right direction of which libraries to use, and or direct me to a snippet of sample code which demonstrates how to do this? 

2) Whatever the approach in 1 above, I need to convert from taking a video file as input, and instead taking captured frame data as input. 

Any help with these two things would be greatly appreciated. 

Cheers, 

Brad

It is called alphabetical order.

I did notice that the libfdk-aac wrapper seems to support up to 5.1:

libavcodec/libfdk-aacenc.c
148:    case 1: mode = MODE_1;       sce = 1; cpe = 0; break;
150:    case 3: mode = MODE_1_2;     sce = 1; cpe = 1; break;
151:    case 4: mode = MODE_1_2_1;   sce = 2; cpe = 1; break;
152:    case 5: mode = MODE_1_2_2;   sce = 1; cpe = 2; break;
153:    case 6: mode = MODE_1_2_2_1; sce = 2; cpe = 2; break;

however the library appears to support up to MODE_1_2_2_2_1 so  maybe
it would be possible...

I don't think mobile safari supports the autoplay option. I got it to

Hmm.  I guess this is a request to be able to make them order-able or
order by default by "highest quality" (for instance, if there were
another encoder than libx264 for h264, *nobody* would want that for
the default, I'd wager).
Cheers!

That command won't choose any audio codec at all.
"-an" means no audio.
;-)

If you're particular about which aac codec is required, why leave it to chance?


For libfdk-aac use a command like this:-
ffmpeg -i yo.mpg -c:v libx264 -c:a libfdk_aac -b:a 128k -ac 2 -ar 44100 nul.mp4

	header is at the end?
Message-ID: <Pine.NEB.4.62.1208010053210.10327@users.757.org>


Howdy everyone!

I've been toying around with trying to use ffmpeg server and streaming.

I have a unit that writed h264/mpeg4 video to disk, already hardware 
encoded (Blackmagic Designs ATEM Television Studio.)

At first I thought I could write it to network attached storage, and open 
the file from players such as VLC. No go.

It turns out what I would call the header is written at the end of the 
file by the Blackmagic unit's software.

The minute the file is closed players have no issue. Before I understood 
that the information about the streams in the file were at the end, I was 
trying netcat and tail and all sorts of hacks.

Is there a way to tell ffmpeg what kind of video is there (overriding the 
need for the information in the file as I can predict what it will be), 
and use it to read the data being written before the footer is there and 
forward this off to a streaming server?

The unit's hardware encoding capabilities deliver full 1920x1080 
h264/mpeg4, just no ability to stream. Tried using a HDMI capture card but 
it's stupid trying to run a huge computer to re-do what is being done 
already.

Any help is greatly appreciated!

Update to current git head and search for "MPEGTS muxer".

As you can see, this is really ancient by now.

I am completely new to this area. This is my first post .. please help!!!
I am building Chromium (Developer build 145856 Windows), modified it to support Mpeg2-TS Video codec. This build doesn't seems to make any ffmpeg dll's  but copies them (avcodec-54, avformat-54 & avutil-51 dll's) from repository to an executable directory. I think these dll's only implements stubs. I have tried to download and copy the dlls from Zeranoe FFmpeg Builds - so far it fails to work. Does anyone knows how to use this dll's with windows chromium build?

Thanks Michael this link solved the first part of my problem.
Effectively I would like to do the same thing but with video stream.

Yes exactly.
Sorry that I haven't pointing this out earlier.
I can watch the camera stream using ""mplayer
rtsp://<my-ip-address>/stream1"

You're right. But I want to try it, to be sure 
Is it possible to have the reference frame for each camera?

The latest news is a few days old:
http://sourceforge.net/mailarchive/forum.php?thread_name=500CD44E.9000803%40gmail.com&forum_name=mingw-w64-public

And I do know why Zeranoe uses pthreads: libvpx 1.1.0 needs an external
symbol pthread_once, which is only present in the pthread version of
ffmpeg. libvpx 1.0.0 can still be linked into ffmpeg.

BTW: across the North Sea the temperatures are up again.

Message-ID: <1343819098.20409.YahooMailNeo@web122504.mail.ne1.yahoo.com>

Hi,

I want to check my written source code for (mpeg-2/4) video/audio parsing is giving correct value or not, I want to check output of each and every field of my code with some good tool's output.

Let's say, if in any stream, my code gives PTS value as 39585729 for some TS packet then that tool should also give me same PTS value. Another example is if in any stream, my code gives output of 'temporal reference' as 9 then that tool should also give 'temporal reference' value as 9.

I need some free source tool to "parse mpeg2/4" stream (ts stream).

Regards,
Pranav.

It's exactly the same process as in the link Michael provided.  Just give  
the stream as your "input file."

TSTools (http://code.google.com/p/tstools/) may be of some help in taking  
apart the transport stream.

LOL true.  Yeah the behavior is *without* the -an :P

Yes I suppose that's seeming like my best option for now .

This build doesn't seems to make any ffmpeg dll's  but copies them (avcodec-54, avformat-54 & avutil-51 dll's) from repository to an executable directory. I think these dll's only implements stubs. I have tried to download and copy the dlls from Zeranoe FFmpeg Builds - so far it fails to work. Does anyone knows how to use this dll's with windows chromium build?

If they only implement stubs, I wonder what other files they are

Interesting.  I wonder if you can still "get around it" by just using
LDFLAGS="-lpthread" but then telling libx264 and ffmpeg *not* to use
pthreads (so they use windows native threads for now). I'll experiment
around with it sometime.

Subject: [FFmpeg-user] first frame is no keyframe
Message-ID: <1343841663388-4652215.post@n4.nabble.com>

Hi guys,

I am using ffmpeg version 0.11.1 on my mac.  Basically I want to be able to
take XD Cam Ex.MOV's recorded at 18mbps transcode them with ffmpeg to
h.264.mp4's to play on an an fms server.  but whenever I do any of this
transcoding with ffmpeg, I get the warning "[mpeg2video @ 0x1a2e3360]
warning: first frame is no keyframe" and the audio is 6 frames or so early
because the fms server won't start playing the video until it sees a
keyframe.  

I've tried forcing a keyframe on the first frame like this:

ffmpeg -i input.mov -force_key_frames 1,2,3,4,5 output.mp4 but it doesn't
seem to have any effect. 

I know that -av seek frame and -ss command might be helpful but I don't know
how to get them to create a file that starts with a keyframe.  Can you help
me?

Thanks very much,

I am trying to control the fps on an WMV output. No matter what I set in the

Any help?

You should provide the actual ffmpeg command and the complete ffmpeg
console output. Without this basic information we can only make guesses.

Please provide the command line you use together with the 
complete, uncut console output (not version information 
separated from a part of the console output).

And please consider testing current git head if you are a user.

Yes, I had them with combined input too.

Sync seems fine here, but I'm yet to test a really long capture.

My personal hypothesis is that it's "dropping" audio packets on their
way in (it probably shouldn't...)

Your input is already 25 fps. FFmpeg will attempt to inherit the input
frame rate for the output if possible.

This is telling you to use -qscale:v or -q:v (same thing, just shorter).

This looks like 25 to me.

Why do you think that the output is 30 fps? What player are you using?

Subject: [FFmpeg-user] Pyffmpeg - updated version,
	or source for older ffmpeg build?
Message-ID: <E37EF404-4594-465D-910A-9B963839539C@cazabon.com>

Hi all - I'm trying to use pyffmpeg on a Mac, and am having issues due to the only version of pyffmpeg I can find seems to be no longer maintained and is out of sync with ffmpeg development.

Does anyone know of a version of pyffmpeg that's compatible with recent versions of ffmpeg?

Failing that, do you know where I can get access to an older version of ffmpeg that supports the last version of pyffmpeg? (march 2011 build of ffmpeg:  (FFmpeg version git-35d7d6f)

I've built all the dependencies/etc, but the version mismatching comes up with a ton of compile errors due to structure changes in ffmpeg since pyffmpeg was last updated.

Thanks,
Kevin.

Message-ID: <1fefb2956579afa8b628da52e8b89172.squirrel@QuestMail.FutureQuest.net:443>

Hello:

I am looking to see if maybe I am missing an alternative to making a mp4
from still images.

I need the framerate of the mp4 (x264) to be 29.97, so I can't use the
typical "-r 5" that people suggest to slow down the animation.  I am
scripting things in perl with imagemagick, so I can easily create some
loops in the script to output 15 frames of each image, making a frameset
of a couple 100 frames, but that seems a bit "the long way around the
barn".  But, this may be the only way to do this.

I just thought I would check with people to see if there is something I am
missing in ffmpeg so that it knows to make 15 frames out of the same still
image before going to the next image in the still set, while creating the
output movie.  I have been looking around different forums and the
documentation, but not really finding anything that seems to work like
this.

Thank you for any help with this, if there is a solution other than
creating all the frames individually.

John

git checkout 35d7d6f ?

Note that for the obvious reasons, you are heavily discouraged 
to use non-supported versions of FFmpeg.

Command line and complete, uncut console output missing.
(Sorry, but ffmpeg allows you to specify the input frame rate 
for images and the output frame rate for mp4, so I don't 
understand your question.)

Option placement matters.  Try something like:

ffmpeg [in opts] -r 2 -i input%03d.png [out opts] -r 29.97 outputfile

If you need more help, you really should post your command line and
complete console output.

If you need variable intervals, the simplest solution is to "duplicate"
frame images with softlinks as needed.  No extra disk space, and ffmpeg
doesn't care.

Subject: [FFmpeg-user] cutting at keyframes?
Message-ID: <1343919770666-4652236.post@n4.nabble.com>

Hi all,

Is it possible to remove all of the audio and video frames for a given input
up until the first video keyframe? In my previous post I mentioned a problem
we are having where h264 .mp4 input files that do not start with a keyframe
play out of sync in FMS, because it does not play the video until it reaches
a video keyframe, whereas the audio starts right away.

If anyone has insight, I'd really appreciate it. 

Thanks,
Greg

Please provide the sample.
(I am unsure what else to say since in your previous post 
you are mentioning a problem with an input file containing 
mpeg2video.)

I thought that the  "-r 25" would do the job.

Subject: [FFmpeg-user] using spdif demuxer
Message-ID: <501A6B54.7020202@freenet.de>

Hi,

I want to playback sound from a USB soundcard's S/PDIF input with ffmpeg. So far I managed to get this working straight forward with PCM:

ffmpeg -ar 48000 -ac 2 -f alsa -i plughw:1,0 -f alsa hw:0,0

Now I want to use this also for ac3 or dts. -f alsa option will not work together with -acodec ac3.
-f spdif should in my understanding be the right selection for spdif input demuxer, but this will not go together with alsa plughw:1,0. So how can I do this?

Hi Carl,

Thanks.  I wasn't clear.  Let me try to clarify,

The codec of the input file 01087001.MOV is mpeg2video (main) in a .mov
container.  I have to transcode it to a file synctest2.mp4 that will play on
our fms server.  The output file that I want to play on the fms server is
codec h.264 in a .mp4 container.

 Ultimately I want the output file to start with a keyframe so that it will
play in sync - but it appears as if the input file does not start with a
keyframe.  I tried to force a keyframe - see below.  But that didn't work so
I was wondering how to cut off all frames till both audio and video on the
output file start at the first video keyframe

-f mjpeg does not support audio.
(I hope this answers your question.)

S/PDIF is not implemented in FFmpeg's ALSA muxer and demuxer. Patches are
welcome.

Apparently it did, and was also not needed in the first place because
your input was already 25 fps.

I don't think FFmpeg is able to produce an output file that 
does not start with a keyframe (when encoding which is what 
you do above).
In other words: I am 100% sure your output file starts with 
a keyframe.

Is your output file out-of-sync if you play with vlc, ffplay, 
MPlayer or QuickTime? (If it plays out-of-sync with 
QuickTime, please also test the others.)

Hi Carl,

Thanks,

It does play in sync with quicktime and vlc.  It doesn't play in sync on
flash media server.

what codec is input.mov? mpeg2?
Is the first frame a keyframe? (ffprobe -show_packets I think should
tell you...)

I think this is related to a question I asked earlier but received no
answer...[1]

[1] https://lists.ffmpeg.org/pipermail/ffmpeg-user/2012-July/007925.html
It appears to also have been discussed in some detail in this thread:
http://ffmpeg.org/pipermail/libav-user/2012-July/002510.html
I'll probably add to that discussion...

I described this for a similar use-case here:
http://www.nvnews.net/vbulletin/showthread.php?t=157347
I currently cannot test, but I suspect the following should work:
$ ffmpeg -i input -acodec ac3 file.spdif
$ aplay -D iec958 -c2 -fs16_le -r48000 file.spdif
(Just to make sure: c2 fs16le r48000 has nothing to do with the 
actual number of channels and rate in your input file, it is 
absolutely necessary for AC-3 and DTS via spdif.)
I am not sure about the value for "D", just found iec958 googling.

Afaict, the cases are completely unrelated because in one 
case -vcodec copy is used while the OP here is using an 
encoder meaning the first frame of the output file will 
be a keyframe (no matter if it is a broken frame or not).

How do you determine the output frame rate? Windows Explorer always
reports 30 frames/second, even if it is 25fps. Try MediaInfo as a better
tool: http://mediainfo.sourceforge.net/en

Hi all!

I'm html5media to embed html5-videos on my website!
The videos are created automaticly with ffmpeg on the server with these codes:
--------------------------------------------------------------------------------------------------------------------------------------------
/xxxx/ffmpeg -r 8 -f image2 -i www/xxx/Alarm%5d.jpg -s 500x375 -b 1035k -y www/xxx/Di_Fahrt_1.mp4

/xxx/ffmpeg -r 8 -f image2 -i www/xxx/Alarm%5d.jpg -s 500x375 -b 1035k -y www/xxx/Di_Fahrt_1.ogv
--------------------------------------------------------------------------------------------------------------------------------------------


It works great in FireFox 14.0.1 and also in Opera (Next) 12.50 internal!

But there are different problems in following browsers!

Safari 5.1.7 (an Windows):
Complete slow and not loading(!?!) and playing all the videos!

Safari 5.x.x (on Mac):
Loading the videos but playing a green movie!

IE9:
Only showing the flowplayer in the compatibility modus
Only playing the older, short videos, but not loading the new ones!?!

Chrome 21.011.xx:
Only playing the older, short videos, but not loading the new ones!?!
(Fahrt 1 and Fahrt 6 are new from today!)
They are not working, the others yes ...?!?

iPad3-browser:
Sometimes not loading the posters of the videos!
Only shows black screen with the PLAY-Button ... Sometimes!

I think there is a codec problem, producing the movies?!?
Is there any way to force ffmpeg to use a special codec?!

If I produce my movies with "Images To Video" => http://en.cze.cz/Images-To-Video offline at my Win7  machine and put them
The the website they are working well?!?


My samples you can find here:

Message-ID: <CAJDvJJc+rFMLFpLywMjb0tHWRoWcgE6qs9Ao94UJdm82GKuyZg@mail.gmail.com>

Hi All,

I am trying to encode a simple *bmp* frame into mpeg1video format.. As i
call *avcodec_encode_video*, a segmentation fault occurs.

I avoid to set specific format, and try to leave this responsibility with
ffmpeg...The only fields i set are:

    pCodec_ctx_output->bit_rate = 400000;
    pCodec_ctx_output->time_base.num = 1;
    pCodec_ctx_output->time_base.den = STREAM_FRAME_RATE;
    pCodec_ctx_output->gop_size = 12;
    pCodec_ctx_output->pix_fmt = STREAM_PIX_FMT;
    pCodec_ctx_output->mb_decision = 2;

A tried many values with no success.

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

Any suggestion about this function usage and frames/codec setup?

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

Regards,
Jorge.

Thanks Carl - I had tried that and I had problems checking out the old version? I _think_ I've figured out how, and thanks for confirming it should be possible, but I'm still having a bunch of problems compiling (due to the changes in multiple dependencies since the last working version of pyffmpeg).  Thanks for the help!

(Still - if anyone has suggestions on a more up to date interface with Python, I'd love to hear it!)

Kevin.

You could try OpenCV. It has python and some ffmpeg support.

All XDCAM files I have seen (exported by Final Cut Pro or directly
written by Sony Cameras) start with a B-frame that is completely
intact. This might seem strange but AFAICS the spec allows B-frames to
only have a forward reference, which is probably the case in those
files since the frame decodes and looks fine in all samples I have
looked at with ffmpeg. I think it was Baptiste who once said the
message was bogus and I tend to agree. However, ffmpeg reports an
incorrect start time for the video stream of these files
(http://ffmpeg.org/trac/ffmpeg/ticket/479) which might be related to
it starting with B-frames as ffmpeg seems to incorrecly use the pts of
the first I-Frame as the first pts of the stream (definition of start
time for a stream, see docs). No idea in what places this might cause
errors like A/V shift. I haven't tested that thoroughly.

Hope this helps somewhat.

Regards,

Robert

Hi Guys,

I've a similar problem with frozen ffmpeg instances, 2 of 8 instances is
frozen, cpu usage on each instance drops to 0. I've tried to remove -threads
parameter or set -threads 1, result is the same.

I've uploaded video file and 8 cmds to fileshare:
http://turbobit.net/7ff93nfen4pw.html

You can use start.bat to start 8 instances at once. I've attached a log
files of frozen ffmpegs:

I've finally made it, thanks to your help, by using this command line: 

ffmpeg -vf select="eq(pict_type\,PICT_TYPE_I)" -i
rtsp://<my-ip-address>/stream1 -vsync 2 -f image2 -vframes 5
"frame-%02d.png"

For me using one of the older builds sorted the problem out - try this 
(assuming you're using Windows): 
http://ffmpeg.zeranoe.com/builds/win64/static/ffmpeg-20120409-git-6bfb304-win64-static.7z

I am not sure if it is remote device problem or command line problem.
it is a remote system. It uses 7130 chipset and Honesttech software and 
FMLE detects the stream.
Once it works i will try ffmpeg.

In fact just forgot what I said.
It works when I put video file like file.avi, but when I specify a stream
like this one : rtsp://172.16.17.38/stream1 which use *rtsp and h264* I have
this error:

D:\Documents and Settings\melefebv\Bureau>ffmpeg -vf select="eq(pict_typ

But I can watch all the camera on VLC using stream like
rtsp://172.45.17.38/stream1, rtsp://172.45.17.39/stream1,
rtsp://172.16.17.40/stream1 ...

Note that I can use mjpeg by specify "stream2" but I still have the same
problem.

Thanks for your help

Kind of a request for comment, but...
would it be possible to somehow include "useful" things like
segmenter.c [1] and qt-faststart into ffmpeg's executable somehow?
I know they seem to be useful every now and again...

The segmenter functionality is already integrated into the segment
muxer, qt-faststart could be implemented as a bitstream filter but I'm
not sure...

Message-ID: <CAP9=GZC25q6V1gqT+DO9r7t9z4t=31VQf2K6tfHQW55A5Q2pXg@mail.gmail.com>

i have a question i know is a bit strange.

i was wondering if it's possible to overlay 2 audio channels in the
same video with ffmpeg.

Example: videoX has left audio channel: X and right audio channel: Y

i would like to make it so that it looks like: left audio channel=xy
and right audio channel=xy

i know that setting "-ac 1" pretty much accomplishes this BUT the
metadata obviously shows mono. i'd like to accomplish the same but
with stereo instead of mono.

any ideas?

qt-faststart will require to add an option in lavf/movenc; I guess it will
need a second pass in the write footer callback to fix the offsets.

You can do exactly that with the pan audio filter. There are examples in the
doc.

Some sort of qt-faststart can be obtained by using
'-movflags frag_keyframe+empty_moov' it seems:

Subject: [FFmpeg-user] Grayscale x264 convertion
Message-ID: <32138320468.20120803135750@io.ua>

Hi,


Would someone advice how to convert video to grayscale?

For example, -pix_fmt gray returns:
Incompatible pixel format 'gray' for codec 'libx264', auto-selecting format 'yuvj420p'

-pix_fmt gray16be returns:
Incompatible pixel format 'gray16be' for codec 'libx264', auto-selecting format 'yuv444p'
x264 [error]: high profile doesn't support 4:4:4


Thanks in advance,
Andrew

x264 does not have a dedicated mode for encoding a single greyscale
plane because I recall it was said to be not any more efficient than
empty chroma planes.  So with greyscale input, any colour space (pixel
format) will be greyscale.

If you want to force a colour video to become greyscale, I don't know
how you would do that using ffmpeg.

i'm not sure i understand the docs.. this is what i have so far:

ffmpeg -async 1 -i b.mpeg -f mp4 -c:v libx264 -preset slow -g 60 -b:v
1000k -s 854x480 -aspect 16:9 -vf "pan=stereo: c0=c0+c1 : c1=c0+c1"
-c:a libvo_aacenc -b:a 128k -ar 48000 -ac 1 -threads 0 -y
audiotes1_pan.mp4

this isnt working

pan is not a *v*ideo *f*ilter.

And you should be dividing by 2 to avoid overflows: c0=0.5*c0+0.5*c1 or
c0<c0+c1.

Define this.

Please test current git head and please post the following:
The configure line you are trying
When make fails, run make again, then run "make V=1" and 
post the output of the last command.

"Media type mismatch". -vf stands for video filter as Nicolas said. You
should try to guess the equivalent for audio filter.

Also, please consider pasting the full FFmpeg output if that still doesn't
work.

It is extremely unlikely that this command does what you want - 
ordering of options is relevant for ffmpeg and you invoke a 
filter before decoding a picture which probably is not what 
you intended.

(And you don't need -f image2 - ffmpeg knows what .png is.)

Can you tell me what effect -vsync 2 has?

(which is what qt-faststart does) are not the same thing.

Yes, I need to convert color video to grayscale. Its oddly. Seems, its
just a special case of color one.

Message-ID: <CAL9861f38qAD6kCcBTe3871ydxLxdwi93S9uTwWA8U9_MWK07w@mail.gmail.com>

Hello Everyone,

I am trying to compile the ffmpeg source code following the guideline
below. I am using ubuntu 11.10
http://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide

This is an excellent guide. But I have a small problem.  I wanted to
install all the binary and libraries in /opt/ffmpeg including libvpx and
libx264.

However when I try to configure ffmpeg it is throwing error:
ERROR: libvpx decoder version must be >=0.9.1

So it seems ./configure could not locate the libraries I compiled before in
/opt/ffmpeg/lib

How do I make ./configure happy? How do I specify the library path to
search for as an option to ./configure?

Thanks -Abhijit Das

LDFLAGS possibly?

Maybe convert it to "gray" then to yuv444p or whatever works well there.

 -vf format=gray,format=yuv422p

Isn't gray alone sufficient? (Without the second format filter.)

What he's trying to say is that this list is not about ffmbc, even if
someone may give you hints about what's going on there maybe it's a
better idea to ask directly to the ffmbc list admin(s).

P.S. Avoid top-posting on this list.

This is what I am currently using:

And the output is ok, but the filesize is a bit large.  If I try and lower
the bitrate, then things in the images start to fall apart real fast.

The images all have the same background (topographic map for weather
radar), and for the most part only the radar image changes from each still
to still. It's a set of 41 stills that output to about a 8 second video,
560KB for the last test file.

Is there anything else that I could possibly do that might keep the same
quality I have now, but bring the file size down?

I don't really use ffmpeg extensively, so I am not familiar with all the
bells and whistles.

Thanks again for your time and help!

John

Hi All,

I am an user of FFMPEG and I am trying to implement Apple HTTP live
streaming with it. I am using the FFMPEG segmenter to segment the input
file. I could see that issue with seeking is fixed with ticket #649.
But I am still having the seeking issue. If I try to seek somewhere in the
middle of the stream then the it moves backward to the beginning of the
stream.

I am using the latest version of FFMPEG
*
*
*ffmpeg version N-42547-g7543fd8*
*built on Jul 16 2012 18:07:09 with gcc 4.4.3*
*
*
The command which I use for segmenting is -
*
*
*ffmpeg -i low64.mp4 -c copy -map 0 -vbsf h264_mp4toannexb -f segment
-segment_list_type ext -segment_list low64.list -segment_list_size 0
-segment_time 10 -segment_format mpegts low64stream%d.ts*
*
*
Could you please advise if the latest version of FFMPEG has the fix for
ticket #649? If not where can I find it?

Regards,
Geetha

sudo apt-get -y install build-essential git yasm
cd
mkdir -p junk/src
git clone git://git.videolan.org/x264
cd x264
./configure --prefix=$HOME/junk --enable-static

make install
cd
git clone --depth 1 git://source.ffmpeg.org/ffmpeg
cd ffmpeg
./configure --extra-cflags="-I$HOME/junk/include" \

Hi,

I need to know *how to add a new test case for RTP  depacketization of AC3* ,so
that it can be tested in regression tests.
Also do the  test cases for RTP depacketization support for AMR, ASF, H.263
exists in the regression tests for ffmpeg.

My test static build script includes...

./configure \
--extra-version=by_Tim \
--enable-static --disable-shared \
--prefix=$SYSROOT/usr/local \
--libdir=$SYSROOT/usr/local/lib64 \
--samples="../fate-suite/" \
--extra-cflags="-static -I$SYSROOT/usr/local/include" \
--extra-ldflags="-static -L$SYSROOT/usr/local/lib64" \
--progs-suffix="_$build_date" \

Having set $SYSROOT to my desired location.

Well, i did contact Baptiste, but he did not respond (and thats very unlike 
him.)
And for Lou, i know where the list is, i'm a member.
I was hoping someone did had have contact with Baptiste lately.

 -vsync 2 : prevents ffmpeg to generate more than one copy for each key
frame.

I'm using : *select="eq(pict_type\,PICT_TYPE_I)" * in order to passing only
"reference picture" (key frame) to the output. Do you think that this filter
is the problem?

Thanks,
Marc

Hello,
No - I use almost exactly the same command as before. I also managed to go
back to using AAC. There are occasional hangs - but much less frequent.
Say, once or twice per week, however such fallout is not an issue to us.
Here's the current command:

ffmpeg.exe -i #in# -f mp4 -vcodec libx264 -pix_fmt yuv420p -s 1024x576 -b:v
2000k -g 33 -acodec libvo_aacenc -b:a 128k -ar 44100 -vf "movie=#logo#
[wm]; [in][wm] overlay=10:main_h-overlay_h-10 [out]" -y -loglevel panic
#out.mp4#

I'm planning to do some testing today and tomorrow, so hopefully I'll be
able to give you some more info.

Cheers,
Luke

Subject: [FFmpeg-user] Extract image every x frames?
Message-ID: <20120806142151.16253599y1o506ov@webmail.tuwien.ac.at>

Hello,

I've found several examples of how to extract images from a video  
using ffmpeg. Unfortunately, my use case seems less popular, and I'm  
not sure how or if it is possible with ffmpeg:

I'd like to extract a frame exactly every 1500 frames - on material  
with different fps rates.

Any hints/tips/tricks welcome! :)

Thanks,
Pb

please can anyone help me.

i have the following command for ffmpeg:
ffmpeg -re -f h264 -pix_fmt yuv420p -i rtp://239.0.12.1:5000 -loglevel debug 
-r 40 -profile baseline -acodec copy -vcodec copy -vsync 0 -copyts  -f h264
udp://10.0.254.47:1001

ffmpeg is running on the debian server , x64.

when i'm trying to get the output stream , i get nothing. 
if i'm looking on the listening ports also nothing.
what is the issue of the given problem ?

the error log is the following:

Does ffplay work with
rtp://239.0.12.1:5000
?

i may be wrong but "-r 1500" might do it

I don't think this works the way I'd need it to, because:
"$ffmpeg -i video.mpg -r 1 -f image2 out-%03d.jpg"
exports 1 image per second (if fps=25).

I'd rather need something like "-r 1/1500", but that won't work :(

UPDATE:
I've now used ffprobe's XML-output (to get FPS) and a batch-loop and  
bc-math to calculate the 1500 frame stepsize as seconds to feed to  
"-ss":

//---------------------------------
while (true); do
         START=$(($MINUTE * $STEP_SIZE))
         START_SEC=$(echo "$START / $FPS" | bc -l)
         START_SEC=$(printf "%.3f" "$START_SEC")

         IMAGE_OUT=$(printf "$DIR_OUT/$SIGNATURE-%03d.jpg" $MINUTE)

         local CMD="$FFMPEG -i $VIDEO_IN -ss $START_SEC -vframes 1 -f  
image2 -sameq -vcodec mjpeg $IMAGE_OUT"
         echo $CMD
         eval "$CMD"

         MINUTE=$(($MINUTE + 1))
         if [ ! -s "$IMAGE_OUT" ]; then
             # If no image was generated, exit the loop:
             echo "done."
             break;
         fi
     done
//---------------------------------

Not sexy, but it works...

you could extract to images then select every 1500'th image.
 -vf select='not(mod(n\,15))'

might be helpful, too. "n" is frame number I...think...

Subject: [FFmpeg-user] alpha channel "overlay" or "movie"
Message-ID: <8C30916E-8132-40E0-AFC3-5171D91D4DD8@gmail.com>

Hello,
I'm trying to overlay a video with a second video containing alpha channel. like this:

ffmpeg -i video1.mov -i video2.mov  -filter_complex "scale=512:304,overlay=0:0" video_result.mov

the result contains both video1 and video2 but the background of the video2 (which contains alpha channel) is black.
I've tried using different codec like "qtrle" or "png" or to specify different pix_fmt but no alpha channel.

I also tried to use the movie filter like:

ffmpeg -i video2.mov -vf "movie=video1.mov:seek_point=0 [movie]; [movie] overlay=0:0 [out]" video_result.mov

same result, no alpha channel.

do you have any advice to achieve one single video with alpha channel overlay.
thanks in advance

Filippo

Put the -filter option after the -i option. It is an output option, not an
input option.

that worked!
BUT this must be new. i tried just tried with an older version of
ffmpeg and it still deinterlaces with the option before the input.
i've always been putting it before.

Please post the complete console output so we can see more precisely what is
happening. Adding "-loglevel verbose" would be a good idea.

In this case, this is more or less equivalent.

Yeah for me this command:
"C:\\downloads\\ffmpeg-20120409-git-6bfb304-win64-static\\ffmpeg-20120409-git-6bfb304-win64-static\\bin\\ffmpeg.exe
-threads 6 -y -i sintel.mpg -pass 1 -t 75 -c:v libx264 -an nul.mp4"

results in these timings:

[6.6186, 6.6536, 6.7067, 6.7275, 6.7331, 6.7605, 6.8356, 6.9484,
7.0748, 7.1302, 12.1823, 13.9774, 16.0897, 17.1871, 18.0254]

so it's failing like 1/3 times, but YMMV.

However, if I specify "-threads 1" it seems to run all right.  I'm
checking into it a bit...

Hi,

    I am trying to get audio from a usb microphone, instead of the 
built-in microphone. The following commands will get the audio from the 
built-in microphone:


ffmpeg -f x11grab -r 30 -s 720x480 -i :0.0+10,100 -f alsa -ac 2 -i 
pulse -mbd 2 -trellis 2 -cmp 2 -subcmp 2 -g 100 -target ntsc-dvd -aspect

ffmpeg -f x11grab -r 30 -s 720x480 -i :0.0+10,100 -f alsa -ac 2 -i hw:0 
-mbd 2 -trellis 2 -cmp 2 -subcmp 2 -g 100 -target ntsc-dvd -aspect 16:9 
out.vob

Most of the other commands record nothing. (I think hw:0,0 records from 
the built-in microphone too.)

I'm getting this error on configure:

[Iusr_3741180 at p3nlhftpg019 ffmpeg-0.11.1]$ ./configure
gcc is unable to create an executable file.
If gcc is a cross-compiler, use the --enable-cross-compile option.
Only do this if you know what cross compiling means.
C compiler test failed.

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

The config log is attached.

Yes, -vf format=gray is working!

Thanks to all, especially to Roger Pack.

Carl Eugen, yes, gray alone is sufficient. Moreover, format=yuv422p is
incompatible with the high profile.

Is it sufficient to code grayscale video with 50% of bitrate comparing
to color coding? I dont know about yuv420p (have no idea about planar
formats), but in yuv422 50% of bits belong to luminance channel.

Thanks!

Hi  all

    I have read the av_image_check_size() function  and find that  the width
and height  all  have add 128.so  why  does  the width and height must  be
added 128?

 Thank you!

Hello,

I have a question,

Do all the video encoders use the same dct? 

I want to change something on it,but I don't know where it is ?

Did you try "hw:1"? If it does not work, please post the full console output
for it (but you can omit all the video-related options for testing).

So that codecs, filters and so can write "(width + 31) * height" without
having to check for overflow. It is just a safety margin.

avi supports all (useful as opposed to codecs specific to a

I cannot really answer this question, but I believe you 
severely underestimate the many features of video coding 
and especially of h264.
(No.)

(This is the end of the tiny file you attached)

I don't think you have a C compiler installed on your system.
If the name of the compiler is neither cc nor gcc or if the 
compiler is not in the path, you can use --cc=/path/to/compiler 
to allow compilation.

That sounds extremely unlikely.

Did you grep for dct in the FFmpeg sources?

Tried, but it didn't work as expected :(
I've tripple-checked the equation and it makes perfect sense...

It outputs frame 0 (correct), frame #1500 (correct) and then infinitely
write frame #1500 again and again... :(
The duration of the source video is 45000 frames at 25fps. The command
below exported 100 frames (should have been 30).

Anyone got any hint why this is happening?

Here's my commandline and console output:

Both your videos are yuv420p which cannot store transparency, 
so I believe your original question is impossible to answer.

Please do not top-post here, Carl Eugen

See the note on "-vsync" in the example for the "tile" filter, this is
probably the same phenomenon.

thanks for the answer.
I actually can't understand why this output:

> Input #1, mov,mp4,m4a,3gp,3g2,mj2, from 'video2.mov':
>    Stream #1:0(eng): Video: mpeg4 (Simple Profile), yuv420p

loading video2.mov in After Effects I clearly see the alpha channel.

can I try something different?
thanks

I would experiment to see if it "takes" libx264 streams, like:

$ ffmpeg -i something.vob -vcoded libx264 -acodec copy something.mp4

If it "accepts" these files, then ratchet up the quality settings in
libx264 and live happy.

The SETPTS filter might work to add a different starting offset, but

Hi All,

I am an user of FFMPEG and I am trying to implement Apple HTTP live
streaming with it. I am using the FFMPEG segmenter to segment the input
file. I could see that issue with seeking is fixed with ticket #649.
But I am still having the seeking issue. If I try to seek somewhere in the
middle of the stream then the it moves backward to the beginning of the
stream.

I am using the latest version of FFMPEG
*
*
*ffmpeg version N-42547-g7543fd8*
*built on Jul 16 2012 18:07:09 with gcc 4.4.3*
*
*
The command which I use for segmenting is -
*
*
*ffmpeg -i low64.mp4 -c copy -map 0 -vbsf h264_mp4toannexb -f segment
-segment_list_type ext -segment_list low64.list -segment_list_size 0
-segment_time 10 -segment_format mpegts low64stream%d.ts*
*
*
Could you please advise if the latest version of FFMPEG has the fix for
ticket #649? If not where can I find it?

Regards,
Geetha

It would be interesting to figure out which commit broke it...

Does it terminate with an error return value?
Maybe run it through gdb and see.  Also track to see if it is running
out of memory, as librtmp apparently does [?]

I've looked up the note [1], which reads:

"The ?-vsync 0? is necessary to prevent |ffmpeg| from duplicating each
output frame to accomodate the originally detected frame rate. "

I've tried with:
//---------------------
$ ffmpeg -i video.avi -vf select='not(mod(n\,1500))' -f image2 -sameq
-vsync 0 delme_images/%03d.jpg
//---------------------

Same result: Gets stuck at frame #1500 and exports 100 images.

Hm...

Subject: [FFmpeg-user] Resuming broken capture of mpeg-ts stream,
 or capture from certain position?
Message-ID: <1344300205751-4652360.post@n4.nabble.com>

Hello,

I'm trying to capture the mpeg-ts streams of the olympics on NBC's site
using ffmpeg.  It works pretty well but is slow, and after a few hours, the
stream link becomes invalid, cutting off capture.  I need to either find a
way to resume the download (the stream will probably have a different link)
or to start capturing from where it got cut off.

I've tried using the command ?-ss position (input/output)? before the -i and
putting the position to where it left off but it just leaves the command
prompt waiting.  I'm thinking it's either streaming the beginning but not
recording or something else is the problem.

The NBC Olympics site uses Youtube videos and the link to the actual stream
(a .m3u8 file) seems to change after a while.  Unfortunately, this happens
before I can finish capturing a stream.

Any help would be greatly, greatly appreciated!!  I am so desperate to
capture these olympics before the videos are taken down!!

Thanks!

While I am not the ultimate expert in video codecs, 
I am pretty sure the MPEG-4 ASP specification does not 
mention transparency.

I don't see anything in the command line you posted

Hi Carl,

I tried seeking through the progress bar in the HTML5 player which plays my
HLS streams. So say for example if I try to seek to 0.15 min, my stream
goes back to 0.10 min which is the beginning of my stream and starts
playing from there. I have streams of 10s duration.

Regards,
Geetha

This command works for me. I can not help you more without the full console

What could be the problem?  How can I work around the segfault?

Unfortunately, more or less anything. Does it segfault too with "-f null -"
instead of "output.avi"? Can you produce a valgrind dump (using ffmpeg_g
rather than ffmpeg), and/or a gdb backtrace?

> The video is approx. 17MB, so I can provide it if required.

Unless you manage to reproduce the segfault with readily available material
or purely internal features, that would be nice. The simplest way is
probably to see if you can reproduce the problem with only the first few
megabytes of the file, and attach it to a trac ticket.

Hm. Puzzling.
I've now tried it on another computer (at work) and here it works now.
I'll check my installation at home to see what went wrong there. Thanks.

However, it's incredibly slow!
When I extract the keyframes using the looping method, it's done in a  
second, whereas using the "-vf select" filter it takes almost 15  
minutes (!) to process a 30 minute ffv1 PAL/SD file.

The image file for the first frame (frame #0) is written after a few  
seconds, whereas I'd assume that it should be instant, no?

Am I doing something wrong?

Thanks,
Pb

Yes Carl, you are right. After Effects was sowing me something that wasn't there.
Tested a new video coded "PNG" and the overlay filter worked fine

Thanks a lot for your help.

Subject: [FFmpeg-user] MPEG: embedding metadata is not working
Message-ID: <20120807141532.94843akzhg6wjx7o@webmail.tuwien.ac.at>

Hello again :)

I'd like to embed some metadata (title, archive signature, ...) into  
an existing .mpg file (mpeg-PS), using the following command:

//---------------------
$ ffmpeg -i video.mpg -acodec copy -vcodec copy -metadata title="Title  
Test" output.mpg
//---------------------

I've googled for any examples, and found examples in the "FFmpeg  
MultimediaWiki" [1], and the syntax shown there matches mine.

I would have expected that "output.mpg" now has the title metadata set  
to "Title Test", but no metadata is written to the generated file :(
(I've verified using ffprobe and GSpot):

//---------------------
$ ffmpeg -i video.mpg -acodec copy -vcodec copy -metadata title="Title  
Testing" output.mpg && ffprobe output.mpg
//---------------------

I've also tried the first commandline with "-vcodec mpeg2video" to see  
if maybe the "-vcodec copy" led to ignoring the new metadata tags:  
Same result :(

I have also checked back with Debian's repo-version of ffmpeg  
(v0.7.12): Same effect, so obviously there's a misunderstanding on my  
side regarding the metadata capabilities of an MPEG-PS?

Thanks,
Pb

You are doing nothing wrong: filters work with decoded frames, so even if
you want to extract only one frame out of 1500, all must be decoded, even
those that do not change the output at all. Doing things more efficiently is
possible, but would be more complex, and nothing is implemented in ready to
use solutions.

Does it work if you produce Matroska instead of MPEG-PS?

I have not looked into things closely, but I would not be surprised if
MPEG-PS was just not capable of storing arbitrary metadata.

Ah, ok!
Makes perfect sense now. Thank you very much for the explanation.

I ran a ffmpeg_g, but it did not output anything.  Is there anything

Hm.
I must admit that I have silently assumed that it could store at least  
the title, but I've now googled for metadata and MPEG-PS, and I can't  
seem to find any concrete proof whether it's possible or not - which  
in case of a popular format like MPEG-PS would suggest: *not* :(

With .avi as well as .mkv it works as expected.

I've found a nice collection of MPEG-2 standard papers [1], but  
honestly couldn't figure out which one *might* contain metadata  
definitions.

So for now, I'll just assume that MPEG-PS can't hold metadata.

Thanks again,
Pb

To get a backtrace, you need to use debugging tools, such as valgrind or
gdb; ffmpeg_g is just a version of ffmpeg where the debugs symbols are still
present, making the file larger but the backtrace much more accurate.

To see how to produce the backtraces, check out:
http://ffmpeg.org/bugreports.html

Got it, but I can not reproduce the segfault, even with valgrind. Are you
sure it happens with the file you uploaded too?

If so, please describe your build environment exactly.

Regards,

Message-ID: <20120807154120.79526wnba64v29ds@webmail.tuwien.ac.at>

Hi,

I've took the time to write a quick "ffmpeg2mets.xsl" stylesheet,  
which transforms the technical metadata from ffprobe's XML output into  
a standardized structure for audio/video as defined by the U.S. Libary  
of Congress [1][2], and stored in a METS container XML [3].

Duration is stored in ISO8601 format [4], bitrate in kbps and  
samplerate in kHz.

It's no big thing, and also not very robust or pimped, but I thought  
I'd post it in case someone could need it, too:

http://dva-profession.svn.sourceforge.net/viewvc/dva-profession/trunk/misc/metadata/ffprobe2mets.xsl?revision=109&view=markup


Have fun!
Pb

No error messages?

If so, does anybody know if rtmp input uses the real time buffer? (I'm
just wondering if maybe it's "missing" incoming packets so they're
being dropped...)

(basically it went from 40.38 to 40.42)
One interesting note is that 0.04 is "about" one frame at 29.97 fps,
which the input "pretends to be" I wonder if there is an off by one
issue or something...

Actually just doing a test like this (converting mp3 to mp3):

$ ffmpeg -i yo.mp3 -vn -acodec libmp3lame yo2.mp3

over and over yields durations like:
yo.mp3 (start): 50.25 seconds
yo2.mp3 : 00:00:53.28
yo3.mp3 : 00:00:53.30
yo4.mp3 : 00:00:53.32

Something doesn't seem quite right here, the same audio file appears
to be getting longer and longer...

AFAIK there's no way today for one filter to talk to another [please
correct me if I'm wrong]
You might be able to use the scene detection filter, then parse its

Best way to solve the issue is through scripting. You copy/link
the files matching a certain pattern, like in (completely untested):

ORIG_IDX=0
ORIG_IDX_STEP=1500
NEW_IDX=0
while [ -e ORIG-$n.png ]; do
   ln -s NEW_${NEW_IDX}.png ORIG_${ORIG_IDX}.png
   ORIG_IDX=$(($ORIG_IDX+$ORIG_IDX_STEP))
   NEW_IDX=$(($NEW_IDX+1))
done

then you do:
ffmpeg -framerate -i 'NEW_%d.png' OUTPUT

Alternatively we could implement -number_step option, see:
https://ffmpeg.org/trac/ffmpeg/ticket/1445

but I'm not yet convinced that would be a good idea.

As for testing select, consider using showinfo filter like in:
select=...,showinfo
-- 
ffmpeg-user random tip #3
Some few multimedia formats (mpeg-1, mpeg-2:PS, DV) support physical merge 
consistency, which means you can merge two files with cat. E.g.:
cat input1.mpeg input2.mpeg > output.mpeg

You'd think that would be an interesting use case for a "vdupe" video
filter or the like :)

More of a question for libav-user, but I have heard you can use gdb to
"breakpointer" where it sets these values, then copy them to your app.

Yes that part of the documentation is not very well thought (the

tools documentation).

Yes download FFmpeg source code and check in the doc/ directory,
source files are texi (texinfo) files converted to POD/HTML/man pages,
website documentation is in synch with the latest FFmpeg git version.

ffmpeg-user random tip #28
The ffprobe program hosted on Sourceforge is no longer maintained, use
the (much better) ffprobe version integrated in FFmpeg.

How are you capturing? (full command line and console output). What is slow?

Without knowing what's going on, I'd guess that they're timing out the
videos, so you'd need to re-parse and get new links [?]

I take that back, appears you can overlay more than one thing at a time:

Appears the actual problem was that the example docs use single
quotes, which don't work in the windows command line. Perhaps they
could all be changed to double quotes at some point, to prevent
confused people like myself? :)

Hello,

I'm a big fan of the framemd5 functionality for verifying losslessness :)

Unfortunately, it doesn't work for checking the audio.
I presume it's related to how the audio data is distributed among the
frames?

Is there any way to have framemd5 work correctly on audio, too?
(I'd already be happy if it worked for uncompressed audio)


Thanks,

Thanks for sharing this. I was just considering doing this myself. By the way, I drafted up a ffprobe-XML to PREMIS metadata transformation (here: https://gist.github.com/3290340), but see that METS may be more useful. With the ffprobe2premis.xsl file you can apply it with:
ffprobe -show_format -show_streams -show_versions -show_error -noprivate -print_format xml=q=1:x=1 MOVIE.mov 2>/dev/null | xsltproc ffprobe2premis.xsl

Thanks for your input!
As I said, I'm using a bash-loop and it does the job.

After recompiling to latest git, the "-vf select" now also works at home.
Showinfo confirms that it's working correctly.

I've hex-edited the files to see at which byte-offset the fraction's
numbers were stored, and they're stored in reverse order: First the
1001, then the 30000.

Would still be interesting why it's really output reversed.

For stuff that you compare they must have same number of samples in every frame.

There is md5. The only way to make framemd5 output same is to make
both compared codecs output frames of same size - which is not possible.
But you could use intermediate format/codec instead....

I've just checked the .texi source and I think the problem is caused a
number of @includes:

@include syntax.texi
@include decoders.texi
@include demuxers.texi
@include protocols.texi
@include indevs.texi

they just point to ffmpeg's documentation files. Therefore the
misleading/confusing syntax parts in the ffprobe docs.
What about just removing those includes, as they don't make any sense
anyway here.

How would I proceed if I wanted to provide you a patch from my changes?

AFAIK that is currently not possible (but could be by storing packet

One issue here is that while there is rawvideo for framemd5 of video streams, there is no equivalent rawaudio format for audio data. The framemd5 of audio will be applied to signed 16 bit raw audio (even if the source is unsigned or >16 bit). So for >16 bit audio the framemd5 process wouldn't work for losslessness verification since the bit depth would need to be changed prior to the application of the checksum.

Perhaps you could work something with https://ffmpeg.org/ffmpeg.html#asetnsamples.

AFAIK framemd5 works fine for >16 bits, just user needs to make sure that
he compares apples to apples: like same sample format (comparing s16p and s16
is possible because conversion between them is lossless), and same pcm output.

Roger, 

Thanks for the response. I referenced the streaming guide while trying to get the command line working. As for v4l2, not sure, but at the moment I'm less concerned about the camera, and more concerned about trying to convert this command line: 

ffmpeg -i ~/SampleVideo.mp4 -re -r 24 -b:v 1000k -f flv rtmp://localhost/live/SAMPLE_STREAM

into programmatic code. If anyone can point me in the right direction of the proper library / method calls to use, and/or a sample code snippet would be great, it would be most appreciated. 

Regards, 

Brad

I also would have thought so.
If the compared files did not undergo any format-changes (e.g. s16->s32
or whatever), and the same number of samples is in the right frame,
their checksums should match.

I'll try the "asetnsamples" filter. From what I've read in the docs, it
sounds promising.

Pb

It worked!

// ----------------------
$ ffmpeg -i video.avi -filter_complex "asetnsamples=n=96000" -f framemd5
video.avi.framemd5
// ----------------------

I've applied the above call to 2 videos (one ffv1.1 the other ffv1.3),
and the framemd5 output shows lines like this for audio:

//-----------------------
0,      96000,      96000,    96000,   384000,
856c852b100fa835447df9dd48a71fe5
// ----------------------

So, it looks like the 96000 samples stunt really worked! :)

Thanks,
Pb

I find the link to the stream on NBCOlympics website using Firefox, then I
type in the command prompt: 
ffmpeg.exe -i URL -c copy out.ts

What is slow is the capture.  Because the streaming link becomes invalid
(and thus capture stops) before I can capture the entire stream (a few hours
after beginning the stream).

> It does nothing? 

I've tested by positioning it to just a few seconds after the beginning
(like 10 seconds).  It does work, but like I said, I think ffmpeg streams
the part I don't want it to download before getting to the part I do want. 
So if I specify a position one hour away, after I type 
ffmpeg.exe -ss 3600 -i URL -c copy out.ts
the command prompt just hangs for a long time and I haven't had the patience
to see if it ends up getting to the part I want or not.

The thing is, if the stream link times out where the download left off, and
if using -ss POSITION streams the beginning, then the link'll time out about
the time it gets to where I want it to start recording...  Right?  I don't
understand why it can't just jump to the position I specify...

> Without knowing what's going on, I'd guess that they're timing out the
> videos, so you'd need to re-parse and get new links [?] 

Yeah, to get new links, I just have to refresh the videos.  The problem is
that if I redo a capture, it'll start at the beginning again.  I have found
no way to have ffmpeg jump directly to the position I want.


I'm not too well informed about stuff like this.  I only followed this guide
about how to capture:
http://stream-recorder.com/forum/showpost.php?p=50357&postcount=9
http://stream-recorder.com/forum/showpost.php?p=50357&postcount=9 
http://stream-recorder.com/forum/showpost.php?p=50377&postcount=11

http://stream-recorder.com/forum/capture-stream-nbcolympics-com-t13287.html 


Maybe it's not possible?  I really don't know much more about these kinds of
things.  Thanks again for your reply.

It contains workarounds to several common problems.
In particular, if Valgrind aborted or crashed after

If that doesn't help, please report this bug to: www.valgrind.org

In the bug report, send all the above text, the valgrind

It looks like an assertion is failing.

I'm having the same problem and getting a segfault when using yadif even with testsrc. I have ffmpeg from git-master on both SUSE machines and Macs and this issue only occurs on the SUSE machines. I'd be happy to send logs or traces when I get back to work tomorrow.

Hi All,

I am trying to apply to apply a patch for a ticket 649 (

I suspect mplayer -dumpstream is a simpler solution.

This is (more or less) unavoidable for isom files.
(Since you didn't provide any FFmpeg console output, 
I don't know if that is what the hardware produces.)

If you find a bug, consider to either report it at trac, 
or - if it is a trivial thing like this - send a patch 
to ffmpeg-devel.

The patch was already pushed, there should be no reason for 
you to apply it manually.

But seeking still doesn't work. If I play the segments through HTML5 player
created through FFMPEG segmenter, and try to
seek in the middle of the stream, it goes back to the beginning of the
stream and starts playing from there.

I can send you one the streams I created if you want.

While this may indicate a (important) bug, I would still 
strongly recommend you simply recompile (and consider 
using static linking for ffmpeg this time).

Anyway, the backtrace from a shared installation without 
--disable-stripping is unfortunately useless.

Complete, uncut console output missing and please consider 
providing a backtrace (not from stripped shared libraries, 
that unfortunately does not help).

Does it work with 6f20921 ?

I (think I) know why you did not post the complete, uncut console 
output here, but it would have been possible to post the first few 
and the last few "invalid dropping" messages.

I don't easily remember a report where MediaInfo output was helpful, 
ffmpeg -i output for both (working and non-working) samples may be 
helpful.

I recompiled using --disable-shared and --disable-stripping, and the
problem went away.

Why does it only happen when shared libraries are used?

Does ffmpeg "jump" right for other ts streams?

I have no idea if -ss POSITION jumps right to a certain position for other
mpeg-ts streams.  All other times I've needed to capture stream, the stream
has been easy to capture and I've never needed to use ffmpeg.  I think this
is the first time I come across mpeg-ts streams.

I tried waiting after doing the -ss POSITION.  I waited forever and the link
timed out.  It's clear I won't get the rest of the stream that way.


As for mplayer, I have no idea where you're supposed to enter the command
lines.  Am I supposed to go the the directory where mplayer is with my
command prompt, and then type that command in it?
I open the command prompt (Run -> then I type "cmd").  Then I type
cd C:\Program Files\SMPlayer\mplayer
Then I do mplayer -dumpstream LINK

but all it does is scan my fonts folder.  No idea what's going on...

I guess my first question is "does ffmpeg -ss work at all for url
streams? If it does, does it work for mpeg-ts streams? If yes, then
should this work..."

Well, like I said, this is the first time I've used ffmpeg because in the
past, other methods have worked, methods that were much simpler and easy.

Does it work for all url streams?  Haven't tried so I can't say.
Does it work for mpeg-ts streams?  I've tried it with one of these olympic
mpeg-ts streams on NBCOlympics, giving it a position of 10 seconds and it
worked (so it started recording at the 10 second position).  Yeah, I think
it would work if I wanted to start capturing at a position further after the
beginning, like 1 hour away.  But like I said, it just hangs there and I
think it is streaming it but not capturing, waiting to get to the specified
position.

If that's the case, this method is useless because by the time ffmpeg gets
to where I need it to start recording, the link will have expired again.

*sigh* I think my only option is to either forget trying to capture or
accept capturing a lower quality stream (like 480p or 320p) instead of
1080p.  I can get about an hour recorded of 3 hour 1080p streams before the
links expire, so I should be able to get the whole stream if I accept a
lower quality stream...

I will have to see what I decide...

The ?map_metadata argument allows copying global/stream metadata from input to output.  If you use ?1 as the input file it will strip the specified metadata.  so to strip metadata from global, video and audio streams do the following:

ffmpeg ?i movie.mp4  -c copy ?map_metadata:g ?1:g  -map_metadata:s:v ?1:g ?map_metadata:s:a ?1:g movie.nometadata.mp4

What's your complete command line and uncut console output? Are you
using -vcodec copy? that might speed things up...

Note there is a difference between "?" and "-", and using your command
as is will result in an error:

  Unable to find a suitable output format for '?i'

The problem has (probably) nothing to do with shared vs 
static, but that - as you can see - your version above was 
compiled against one version of libav* but another version 
was loaded at runtime.
This should in theory work - that is why I said this may 
be an important bug - but I am not sure how to reproduce 
here (and it definitely would take some time) and you can 
relatively easily fix it for you by recompiling with static 
linking.

Hi, Thanks Carl Eugen Hoyos:


I just downloaded ffmpeg source code from http://ffmpeg.org/download.html ,
by using git:
git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg

Well, I can't see anything related to
choose_sample_fmts()
choose_sample_rates()
choose_channel_layouts()

I also checked libav from http://libav.org/download.html , there is no
definition of these 3 functions as well. So, since there are only tens of
lines of these functions in your download, can you please just attached
your definitions of these 3 functions from line 666 to after 680 ???



Thank you very much...

Hello all.  I know that today's overlay filter allows for static
images, or dynamic overlays (other movies basically).  Is there
currently any way to get it to overlay with an image where the image
can be updated every so often, during the ffmpeg session?
Thanks.

Look for DEF_CHOOSE_FORMAT in ffmpeg_filter.c

Maybe it needs spaces for the rtmp url, not ?'s ?

Anybody know if the native support was something of a "copy" of
librtmp into the core?

What does compiling with --enable-librtmp do these days? Override the
internal version?

I'm getting reports of ffmpeg streaming to an rtmp server "dropping
fps and eventually running out of RAM"
http://ffmpeg.zeranoe.com/forum/viewtopic.php?f=7&t=657

Anybody have any hints/clues on what might be causing this?
Thanks!

Hi Carl,

I checkout the master 6f20921 and compiled and tried segmenting again. But
I get a core dump if I try to segment. I have installed all the necessary
libraries. Also the 2 files applehttp and applehttpproto which are there
in 6f20921 is not there in the latest version of FFMPEG.

Please assist!

Wrong mailing list. You are using wrong stuff.
Either use right stuff or ask help on another mailing list.

Libav != FFmpeg.

I am sorry. But I actually want to use FFMPEG only. If I try to use FFMPEG

Hi Roger,

Sorry for this. But are you asking me to compile the latest version of
FFMPEG again and then try to segment?

You are not using ffmpeg from FFmpeg project, you are using ffmpeg
from Libav project.

This is still pretty old...

Would you mind trying an up-to-date FFmpeg?

See http://ffmpeg.org/download.html

You will be able to checkout and build the latest version, or even
download a static build for quick testing.

The latest version works fine for me. But I want the fix for ticket 649 (
http://ffmpeg.org/trac/ffmpeg/ticket/649), for which Roger suggested to try
out git version 6f20921. The segmenter of this version is throwing a lot of
error.

$ git checkout 6f20921

Hi,

note that ffplay supports only one input, and doesn't support the
-filter_complex option, which is ffmpeg specific.

You can still support multiple inputs through the lavfi device,
something like:

ffplay -f lavfi "movie='video=screen-capture-recorder':f=dshow
[tmp0]; movie=go.png [tmp1]; [tmp0][tmp1] overlay=10:H-h-10"

Create a video from a single image:
ffmpeg -loop_input -f image2 -i image.jpeg -t 20 image-movie.mpeg

That's tricky, indeed I think that many users use ffmpeg through the
MinGW bash shell, which supports that kind of escaping, don't know
about cmd.com.

How should the image be updated (that is, how should the ffmpeg
process be informed of the change)?

Reconfiguration through dynamic/scripted events should be possible in
principle but is mostly unimplemented.

Message-ID: <4822BBE8545F7B4AAD9F1B08C0EACCFB05FBDA8E@HKNPRD0210MB373.apcprd02.prod.outlook.com>

Hi    

           I have a critical problem. I am sharing the details with you.
            

            Problem: - I have a video file in .mov format, taken from the IPhone. This video is in portrait mode, I want to play this video on the webpage in landscape mode and vice versa.
                             Please suggest me, should I convert my video from portrait to landscape mode using FFMPEG. Does FFMPEG provide this conversion feature? If yes, Please send the exe and the command line for converting portrait video into landscape mode and vice versa.
            
            
Is there anybody that can help me? 

 
            






Thanks & Regards

How should the image be updated (that is, how should the ffmpeg process be informed of the change)?

Reconfiguration through dynamic/scripted events should be possible in principle but is mostly unimplemented.

This describes the syntax used by various (library) components / tools
options.

Decoders are used by ffprobe (-show_frames requires decoding).

Demuxers are used by ffprobe.

Same for protocols.

> @include indevs.texi

ffprobe can read from input devices.

Also note that ffprobe can read from the lavfi device, which makes
use of filters, so it would make sense to include also filters.texi.

As I explained, the includes are there for a reason. On the other hand
it is not easy to document all the features of ffmpeg in a way which
is possibly useful for documenting both libraries and tools.

For example the various doc/ files which document the various
components (codecs, formats, protocols, filters etc.) make extensive
use of ff* example commands, mostly ffmpeg and ffplay commands, which
will you therefore find in the ffprobe manpage.

http://ffmpeg.org/developer.html#Contributing

don't be bothered to read all the stuff, sending a git-format patch
(or simply a diff) should be enough.

Anyway I don't think removing those includes from ffprobe.texi would
be acceptable for the above mentioned reasons.

I suggested to test this version because Geetha wrote that 
applehttp seeking does not work for him.

I only realize now that the problem may not be seeking but 
that the segmented files are somehow not as he expects them.

Subject: [FFmpeg-user] timecode_frame_start option has no effect
Message-ID: <CAN0LTaNxx=ox8-Tr86rnCKkhuUPQ9i04WTZCOTSfEcz3e4VVEA@mail.gmail.com>

I'm trying to cut a video starting from an exact frame position, using the
"timecode_frame_start" option.
For example, I'll use this video:
http://www.seaotter.com/marine/movies/hermit-long-01.mpg

It seems the option has no effect at all, regardless of where I put it. The
resulting video always starts at the same frame position.

Does this have to do with "max_analyze_duration"?

Werner,
This is not what the command does, it is intended to set the start TC value.
(but that probably does not even work on Mp4 output, it does on QT (and 
perhaps other formats).)
Use -ss instead (be warned it might not be frame accurate)

hth,
Bouke

Interesting, thanks!
I also had some success using ffmpeg with the "sdl out" device for the
output, for followers (though it doesn't feel particularly stable...)

My guess is starvation on the input (?)

Yes this (deprecated) function is just to mark the mpeg stream, this is
not what you are looking for.

It won't.

OTOH, you may use -vf select for accurate frame selection (something like
-vf 'select=gte(n\,100)' to skip the 100 first frames); I'm not sure how
well this will work with audio sync though.

The frame accurate seek is a wanted feature, but I don't know if an issue
is already opened for this. You might want to dig on the trac? and
eventually open a new ticket.

Subject: [FFmpeg-user] Transcoding Iphone Portrait videos to DVD
Message-ID: <CAKifF_C53rPEd9uopniUYkZR6ZepJrT6pN-CJg57dG8wvuSnMQ@mail.gmail.com>

Hi,

I am having a bit of trouble converting my Iphone videos (portrait mode) to
DVD format.

Most of the DVD authoring software seems to ignore the orientation of the
videos and so puts the videos in the wrong orientation.

The video specification is as follows:

640 (width) * 480 (height)
Rotation = 90* clockwise (Portrait video)

So I thought ffmpeg is the best tool for this purpose.
Here is what I need to do:

1) Rotate the video by 90* clockwise.
2) Adjust the video to be in DVD NTSC/ PAL format (4:3) such that the video
is not scaled/ distorted.
It is okay to crop/ pad to adjust the video to a different width/ height.

I can easily do 1) by using "-vf transpose=1".

But I am having a bit of problem doing 2) above.

Can someone advise as to which options should be used?

Thanks in advance.

-Devavrat

Here is what I need to do:

1) Rotate the video by 90* clockwise.
2) Adjust the video to be in DVD NTSC/ PAL format (4:3) such that the video is not scaled/ distorted.
It is okay to crop/ pad to adjust the video to a different width/ height.

I can easily do 1) by using "-vf transpose=1".

But I am having a bit of problem doing 2) above.

Can someone advise as to which options should be used?

Thanks in advance.

Subject: [FFmpeg-user] Fatal errors
Message-ID: <2065947791.16402.1344516166442.JavaMail.sas1@172.29.249.242>

Hello

I was wondering if there is any list of ffmpeg errors that should be considered as fatal? Fatal for me means that there is a risk that output file was not properly generated.

During my testing I have created following list (which for sure is not complete and most probably invalid):
"unsuitable output format",
"no such file",
"error codec",
"unknown format",
"unable to find a suitable output format",
"bitstream filter not found",
"internal bug",
"decoder not found",
"demuxer not found",
"encoder not found",
"end of file",
"immediate exit was requested",
"filter not found",
"invalid data",
"option not found",
"protocol not found",
"stream not found",
"unknown error",
"invalid argument",
"invalid too big",
"error opening",
"could not write",
"error while",
"invalid framerate",
"unsupported coding",
"could not find",
"not enough data"

Lately I have faced following errors:
"error while decoding stream #0:1: invalid data found when processing input",
"error while decoding stream #0:0: error number -1 occurred"

However, the output files were "playable". Today I was informed that those two are not fatal, and actually are quite "normal".

I am a bit lost.

Regards
Dawid

-format ntsc-dvd
might help
Assuming you know the aspect ratio previously, you could add some "pad" to it:

I think in general a fatal error will result in an error (process
return code) of "non 0"...if that helps.

Message-ID: <20120809151340.1651259jet8vdh8k@webmail.tuwien.ac.at>

Hi,

I'd like to redefine the aspect ratio of a DVD-conform MPEG, using the  
following command:

//------------------------
$ ffmpeg -i video_in.mpg -acodec copy -vcodec copy -aspect 16:9 video_out.mpg
//------------------------

As the output shows, the "-aspect 16:9" option seems to be ignored:

Hi,
I am trying to use ffmpeg on android device. I have compiled the library and can use it in my java application.

I want to know that if i can record the video of my screen using ffmpeg without giving the rooted permissions to my device.
If not then please help me out on how i can combine image files and audio to create a video file.
There are few posts for the same but they have issues as most of them do not run/compile on windows system.

thanks and regards,

The aspect ratio is not stored in the MPEG-PS format, so the information in
the bitstream is the only source for it. It could be changed with a
bitstream filter, but that is not currently implemented.

Message-ID: <CAHT7zquN+TpgLG2huS8ytYp8X6J_KfgGEduvMcqFpFQ8=MKGsQ@mail.gmail.com>

Hello,

I have a series of 16,000 or  so .tif images that I want to assemble into a
video.  I want the video to be of the highest quality possible, with no
compression. I want to load the completed video into a video editing
program, like Windows Movie Maker 2.6 (I'm just going to make cuts).

I've read online, and gotten it to work, partially.  I'm looking for some
assistance with the command line.

This command line produces a video, but it's not recognizable by Windows
Movie Maker

ffmpeg -b 3600 -r16 -i dw1%06d.tif -target ntsc-dvd dw1.mpg

(tif names are "dw1000001.tif; dw1000002.tif; etc)

This command line barfs:

ffmpeg -b 3600 -r16 -i dw1%06d.tif  dw1.mp4

It returns "width or height not divisible by 2 (835x648)

The tifs have sizes varying by +/- 10 pixels in x and y directions.

Thanks in advance.  I've tried to "read the fine manual", but I just can't
make sense of what I'm reading.

Sincerely,
Eric

I might try using imagemagik [ convert ] to 1st make the tif a 
consistant hxw
also - no mpg is uncompressed
and -- if you are using win movie maker - you might go avi or actually 
wmv w win8 @ 8 Mbps

likely this will be high enough

A risk?

Please understand that afaict the developers do not see 
error strings as part of the API, so whatever you are 
trying to do will definitely break fast.

Try instead to explain what you want to do, perhaps 
someone on the list can help you.

Yes, I want to be sure that the output file was successfully generated and that there is no risk that it is anyhow corrupted. I don't know much about ffmpeg, and I assume that it can exit with code 0 but at the same time write to the output some errors that may (or may not) affect a generated video. This is why I used word risk.

I am using ffmpeg.exe to convert video to mp4 format (among other things). I don't remember why but (I assume) there was a reason why I decided to analyse ffmpeg output for errors (maybe exit code hasn't worked for me in some cases).
So what I want to do is to detect when ffmpeg fails to create completely correct converted file.

Let me try again (differently):
I severely doubt you can define "not properly generated" and 
I therefore find it very unlikely this can be detected.

Now you would have to define "completely correct".

As it is, I certainly cannot help you, if you can 
remember why you decided you want to analyse the output
(preferably a command line with complete, uncut console 
output and an explanation what went wrong), somebody 
may be able to help you.

Sorry, Carl Eugen

I don't know much about ffmpeg, because I still use mainly mencoder. 

With this, you can achieve aspect ratio change with:

mencoder ${file} -fps 25 -oac copy -ovc copy -of mpeg -mpegopts
format=dvd:tsaf:vaspect=4/3 -forceidx -o ${file}.newaspect

Set vaspect according to your needs.

fps is the framrate and optional, as well as the parameters forceidx and
format=dvd:tsaf. See also the mencoder manpage.

Let's just forget what I wrote. Could you try to answer one question...
If ffmpeg.exe returns 0 as exit code, does that mean that the generated file should be ok?

Please don't ask me to define "ok"... :-)

Most likely. Note that if it returns 1, it's still possible the output
file is ok (though in that case I'd say it's usually a hint that your
command isn't 100% right).

You can also set the loglevel (you'd probably want "-loglevel error"
in your case, maybe "-loglevel warning") and read output from stderr
and optionally display it to the user as "these things may have caused
your output to not be quite right" (though a lot of the time ffmpeg
will generate ok output despite reporting errors and warnings, as it
tries its best to recover from these things).

> Please don't ask me to define "ok"... :-)

Then you have to assume you and I define "ok output" as the same thing :)

Subject: [FFmpeg-user] Outputting files to C RTMP Server
Message-ID: <50242858.3050805@pagestream.org>

Hello,

I've tried ffserver and not had much luck, so I'm trying to feed files 
from ffmpeg into c-rtmp-server. This is a series of files being output 
to an mpegts stream, and it works except when the file output has a 
different PAT/PMT table.

So, what can I do to normalize the output? I've considering running two 
copies of ffmpeg, one decoding to some featureless format/stream, and 
another compressing that to mpegts. That seems a bit excessive, but 
should sanitize everything I figure :-)

Are there any other options, or baring that, what would be the best way 
to do the above?

Thanks for your help,

Deron

How do you feed them? How does it fail/what fails?

The files are output like this:

ffmpeg -re -i file1 -s 640x360 -r 29.97 -vcodec libx264 -bf 0 -acodec 
libfaac -async 1 -f mpegts udp://127.0.0.1:11111
ffmpeg -re -i file2 -s 640x360 -r 29.97 -vcodec libx264 -bf 0 -acodec 
libfaac -async 1 -f mpegts udp://127.0.0.1:11111

The "failure" is in crtmpserver. As I understand it, when file1 and 
file2 PAT/PMT tables differ then crtmpserver tries to open a new stream 
instead of continuing to use the existing stream. However, to be able to 
watch these 2 files (it is actually a long dynamic list of files) as a 
single stream, the stream must persist.

Thanks for the suggestion but that won't work for a number of reasons.

1) This list never ends. The plan is a 24/7 output.

2) The list is dynamic. The _next_ file in the list can be changed at 
any time prior to the playing of the file.

3) concat requires that all segments have the same number and type of 
streams. Sadly, some of these file might have 2 streams of mono audio 
(left/right), or 1 stream of 8 channel or... I'm not 100% clear on what 
PAT/PMT contains, but I think this is the same problem that I have to 
begin with.


I can do something like:

ffmpeg -i "file" -s 640x360 -r 29.97 -f avi - | ffmpeg -re -i - -vcodec 
libx264 -bf 0 -acodec libfaac -async 1 -f mpegts udp://127.0.0.1:11111

And as long as the first format (avi in this example) doesn't cause 
differing PAT/PMT tables in the mpegts output, then I am ok. Problem of 
course is mangling like this causes significant damage to video and much 
cpu. I can live with the cpu usage (to a degree) but not the video loss.

Any other ideas? Anyone?

Thanks again,

Deron

Build your own custom "libavcodec" program that does it? Sorry I'm no help :P

Hello dear friends
I have a proprietary software in which I integrated ffmpeg libs (built

audio. I want to start implementing the decoding for G.7111 A-LAW audio 
also. I found in in avcodec.h file CODEC_ID_PCM_ALAW. Is this the type 
for G.7111 A-LAW ? Can anybody guide my steps in order to implement G711

Message-ID: <CAFS+wb8zUjRk_-nS6MGsXfAYcjDYs7ANLd_mD=hp1gAKMVfuQA@mail.gmail.com>

This is in reply to an old thread:
http://ffmpeg-users.933282.n4.nabble.com/Reducing-seek-time-when-start-time-offset-ss-is-large-td1460307.html

I tried to post my reply through nabble but my mailing list subscription
through it doesn't seem to be working.


I'm cutting hundreds of clips from long video files and the larger the seek
time, the longer it takes to cut a clip. I can cut a clip from the start of
a video in about 0.5 seconds and it takes 18 seconds to cut the same length
clip 22 minutes in. The solution in the earlier thread was to use the copy
option for the codecs but when I use them, my video and audio is out of
sync in the resulting files.

My video clips are cut pretty precisely, for example, -ss 00:22:12.540 -t
4.32 which might have something to do with the audio sync issue when using
copy.

I've tried to cut multiple clips in an single encode but ffmpeg doesn't
accept multiple -ss values. Is there an alternative method to speed up
ffmpeg when using -ss or a way to prevent the audio and video from
unsyncing?

Thanks,
Curtis

Subject: [FFmpeg-user] Still Image tifs to video (part 2)
Message-ID: <CAHT7zqt1B-CSuaJFkZNeZ1XH3T2CXeqgYjQKxvSbMpMcohJvmw@mail.gmail.com>

Hello,

I posted a question yesterday and got some good feedback.  Thanks for the
help.

I have a series of 16,000 or so .tif images that I want to assemble into a
video. I want the video to be of the highest quality possible, with no
compression. I want to load the completed video into a video editing
program, like Windows Movie Maker 2.6 (I'm just going to make cuts).

Based on the advice I received yesterday, I used image magick's "mogrify"
command to convert all of the images to 836x650 pixels.

command line "mogrify -resize 836x650! *.tif" worked perfectly.

Now I have 16,000 images all the same size.  I want to creat an avi file
that can be edited in Windows Movie Maker that preserves all of the quality
in the images. File size is unimportant.

I tried "ffmpeg -r 16 -b 3600 -i dw1%06d.tif dw1.avi", but am unhappy with
the results.

Any suggestions? Thanks for the assistance.

Sincerely,
Eric Hollis

What specifically about the output are you not pleased with?

I suggested this:

https://groups.google.com/forum/?fromgroups#!topic/ffmbc-discuss/w6w9Yuo6_oo%5B1-25%5D

on the ffmbc list for the exact same problem (if I understand your
posting correctly). Not a pretty solution but for use cases like yours
(and mine) it does the job. I was going to make a patch against ffmpeg
before posting this here but have not had time yet to do it but I'll
try to do that in the next few days. I hope this is at least going to
get a discussion about this started because I think this may be a
practical problem many people have.

Regards,

Robert

try an increase of that Num.

Thanks for the responses.  Increasing the data rate made things a lot
better. Thanks for the hint about the -t 10 switch...saves much time.

As to the frame rate...I'm converting 16mm film.  I built a projector that
scans each frame of film. That accounts for the odd size frame and the
frame rate.  I'm trimming the frame to include as much of the picture from
the film as I can, and 16 fps is the rate the film originally ran at.

The results are quite good.

Thanks again for all the help.

sincerely,
Eric

Why don't you use ffmpeg to do the resizing?

I don't think Windows Movie Maker allows an 
uncompressed format as input, and I don't 
think -b makes sense for above restriction.

While I don't think -b makes any sense for tif, please 
elaborate what makes you unhappy and provide complete, 
uncut console output.

Let me recap, and correct me if I am wrong:

-ss before -i uses seeking, and is inaccurate since it seeks only to
keyframes; -ss after -i uses skipping and is very slow, you want a new
option that does most of the work by seeking and then skips from the last
keyframe until the target time.

I do not think it is necessary.

The thing is -ss seeks with the "backwards" flag: if there is no keyframe
exactly at the requested time, it will look for a keyframe before it, not
after. On the other hand, the timestamps are adjusted according to the
target time, not the found keyframe, which means that timestamps will
usually begin slightly negative.

Which leads to a solution:

ffmpeg -ss time -i file -ss 0 output

A few tests I ran some days ago shows it is not exactly equivalent to
"ffmpeg -i file -ss time output", but only up to one or two frames. I must
run some more test to find out why exactly.

Nicolas,

Your solution to have a seek time before and after encoding is exactly what
I was looking for. It also very similar to the functionality Robert added
to ffmbc. When I tried to use your example and have a 0 start after
encoding, my clips audio and video were out of sync though. This was easily
fixed by having the pre-encoding seek 5 seconds before the start of my clip
and having the post-encoding seek start at 00:00:05. It looks like it's
working great and it's so much faster.

Thanks,

Curtis

I just want to point out a few things here: this is not entirely
correct. In FFmpeg, seeking actually may not be done by keyframe (even
if AVSEEK_FLAG_ANY is not set) (for example, mpg files don't seek by
keyframe). Also, the "backwards" flag is not always respected (again,
like with mpg files, it may seek to a non keyframe, but then stop
there (and not seek further back to the proper keyframe)).

There's actually some discussion regarding this here:
https://ffmpeg.org/trac/ffmpeg/ticket/1607 where I reported the bug,
but it doesn't look like it's close to being fixed.

Am I correct in assuming that with these options:

-vcodec libx264 -crf 20 -bufsize 2000k -maxrate 2500k


that the "max rate + bufsize" settings basically create a limit on the
quality--i.e. it could at times fall below crf 20 because of those
extra settings?  crf becomes a "suggestion" here?

Thanks.

in my case the requirement was frame-accurate seeking and I am still
getting different (less reliable) results with -ss as an input option
depending on container format and probably other specifics of the
video stream. I have to admit, though, that ffmpeg.c has changed quite
a bit since I have last looked at it and I first have to understand
how it works now to make up my mind whether your approach really has
the same properties as this rather ugly "pre-seeking" I suggested. I
think the main point is to take into account that seeking does not
work equally reliably for every format (which, I think, was also
michael's point) and my approach (at least with the old ffmpeg code
ffmbc is based on) appeared to be more robust in that regard. Need to
do more research though. Might be nonsense with current code.

You already have separated frame images. Instead of glueing them all
together in one video,
and later cut the video into smaller segments, why just don't create
videos with the subsets of frames?

You want to use "-s", as output option, to resize them to a common size.

Neither of those options give you lossless compression (and in fact
the first one should be downsizing your images, which is even worse).
I had to create a video from a bunch of differently sized png images
once on Windows, and here's the command I used:

ffmpeg -r 30 -i %d.png -vf
"scale=min(3360/iw\,1080/ih)*iw:min(3360/iw\,1080/ih)*ih,pad=3360:1080:(3360-(min(3360/iw\,1080/ih)*iw))/2:(1080-(min(3360/iw\,1080/ih)*ih))/2"
out.mp4

My largest image was 3360x1080, which is why you see 3360 and 1080 so
much. You can replace those numbers with the width and height of your
own largest image (or bigger, if you want). This scale and pad command
will add black letterboxing and pillaring as necessary to the video
without resizing any image (and it will center each image).

You have to carefully choose your video codec though. Some video
codecs don't support odd widths or heights (as you can see), and some
give better quality than others. If you want lossless H.264 encoding
with libx264 (I believe it's defaulting to libx264 when you chose .mp4
without specifying the codec), you can pass -crf 0 to get lossless
video.

Other video codecs, like libopenjpeg, will do lossless by default.

Actually, I lied. This does rescale images (forgot I did that on this
one) so they fill the frame as much as they can. A nonscaling version
would be something more like:

ffmpeg -r 30 -i %d.png -vf
"pad=3360:1080:floor((3360-iw)/2):floor((1080-ih)/2)" out.mp4

Subject: [FFmpeg-user] libstagefright_h264 not found
Message-ID: <502561A8.6090904@alcatel-lucent.com>

Building ffmpeg for android fails using the script build_libstagefright
found in tools because it can not find libstagefright_h264. This script
is trying to use the configure option --enable-libstagefright-h264.

How can I fix this error? Or is there another way I can get hardware
h264 decoding on android?

Output of the script run from the ffmpeg root directory. config.log
attached.

$ tools/build_libstagefright
Fetching Android system headers
fatal: destination path '../android-source/frameworks/base' already
exists and is not an empty directory.
fatal: destination path '../android-source/system/core' already exists
and is not an empty directory.
Fetching Android libraries for linking
ERROR: libstagefright_h264 not found

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

Thanks,
Frank

Carl, thank You for You opinion but I do preffer to accept them from
people, who CAN answer the question.

So, may be somebody knows, is it sufficient to code grayscale video
with 50% of bitrate comparing to color coding?

I understand.

What about pointing to the parts of ffmpeg's docs instead of including them?

I might be talking too superficial here, but if I am not the only one
who finds it rather confusing to have the ffmpeg syntax mentioned
without any additional note within the ffprobe docs, what about
mentioning your above listed explanations shortly and then point to
ffmpeg's doc where necessary. Then it'd be clear why these sections
appear in ffprobe.

If so many parts are shared between ffmpeg and ffprobe (which is
understandable), it might be a bad idea to copy text-parts (=fork) the
ffprobe docs just in order to adapt the text there so it better suits
ffprobe's syntax and use cases.

There are ffmpeg conversions shown as examples, which is something that
is absolutely undoable using ffprobe.
Examples: AVOptions [1], Codec AVOptions [2] or Syntax:Color [3].

Ideas?

You are right, -ss as input option is less accurate, as it is, apart from
bugs and misfeatures, limited to keyframes.

But your wording makes me wonder if you did not miss part of my message: I
did not suggest to use -ss as input option but to use it BOTH as input and
output option: the input option causes ffmpeg to seek to the keyframe
immediately before the target time and the output option causes it to skip
the frame to the exact target time.

With formats that have valid timestamps at seek points, it should be
frame-accurate, although it seems to be only frame-accurate?1, and I need to
find time to examine why.

Note that MPEG-PS is rather a crappy format, especially for seeking, which
explains Michael Bradshaw's problems.

Hi,

sorry for not being precise enough in my response. yes, I did
understand your suggestion. My immediate thought was that it could not
do anything as the default value of the variable you set using -ss 0
as an output option already is zero but then I did not write that,
because I realized so much in the code had changed since I last looked
at it and wanted to first understand how the current code works (e.g.
at first glance I didn't find any seek call in ffmpeg.c, which
surprised me). that's part of what I meant by more research needed.

Regards,

Robert

Subject: [FFmpeg-user] FFmpeg fails to build after upgrading libx264 to
	version 125
Message-ID: <201208140100.02902.rodney.baker@iinet.net.au>

Hi all. Last week I updated x264 to the latest git version (libx264.so.125 is 
the new version). Ever since then FFmpeg has failed to build, erroring out as 
follows:

[...]
LD      ffplay_g
LD      ffmpeg_g
LD      ffprobe_g
libavcodec/libavcodec.a(libx264.o): In function `X264_init':

make: *** [ffprobe_g] Error 1
make error - please check your work


I tried checking the sources but I can't find where it is getting this 
reference to 'x264_encoder_open_124'. Should that not be referring to 
x264_encoder_open_125 now that libx264 is updated? 

x264 was updated via git pull, built from source (with --enable-shared --
prefix=/usr) and installed with 'sudo make install' prior to updating FFmpeg 
(again from git). 

Any hints? I'd submit a patch (if needed) if I knew where to look and what to 
fix.

The relevant line says;

 x4->enc = x264_encoder_open(&x4->params);

...but the &x4->params is french to me - where does that get its reference to 
the appropriate libx264 version that it should be looking for? Searching for 
'124' in libx264.c hasn't helped.

Thanks.

Never mind - I found a rogue copy of x264.h from build 124 hiding in 
/usr/local/include which was being picked up in preference to the version from 
build 125 in /usr/include. When I built 124 I must have missed the --prefix 
parameter for configure. This time it built correctly. :-)

Subject: [FFmpeg-user] Frame padding
Message-ID: <CACwc0rY9QWKY3OyX+uOBJYStnJKca__2zAVFxVO0EkCRh-5O7Q@mail.gmail.com>

We view all of our image sequences and movies in either Nuke or RV. Both of
these apps can use %04d for reading images--be it 1-100 or 1001-1100.
FFmpeg, however, needs two different paddings for those two ranges: %04d
and 1%03d, respectively. This leaves me needing to do a switch based on the
input frame length.

In pseudo-code:

    outputFrames = '%04d'
    if max(inputFrames) > 999:
        outputFrames = '1%03d'

Of course, if I have 900-1001, I'm screwed :)

There's got to be a better way of doing this. What am I missing?

silly question: can't you tell your comp/render/whatever app(s) tell to 
fill the padding?
the ones i know do that by default, as far as i know. maybe there's a 
way to tell yours to do the same?
also using ffmpeg here and never had that kind of issue.
having another issue, thoug: ffempeg doesn't handle image sequence 
starting at frame numbers >1.
so i need to work around that in our code. from your example it seems as 
this is working in your environment.
just curious...

To avoid that kind of joke and worse, I have taken the habit of not running
make install as a privileged user: instead, I use "make DESTDIR=/tmp/i
install" as the build user and then only "cp -r" with privileges.

(Apart from the fact that above sentence was never true the way it is written:)
There is now -start_number and -start_number_range, please check ffmpeg -h

Message-ID: <1344918438697-4652537.post@n4.nabble.com>

Hi,
I have some problem with YUV:

1- I convert a ".wmv" file to ".yuv" using the following command:
"ffmpeg -i input.wmv output.yuv"

but when i use a "YuvFilePlayer", it shows nothing special, only some lines.
I'm not sure if it is possible to watch such a file? or I used wrong
command???

2- I have tested to add a container to the raw video file then watch it with
"mplayer", the command is:
" ffmpeg -f rawvideo -s 720*576 -i output.yuv -f flv -ar 44100 output.flv"

but it doesn't work, it outputs no sound and the video looks like the
"output.yuv" described above.

what shall i do?!!!!!!!!!!

You could try the following:

You do realize that yuv files do not contain sound
(so if you use a yuv file as input, the output file 
cannot contain sound)?

Complete, uncut console output for both the conversion to 
yuv and the conversion to flv missing.

sorry if i was wrong there. i, unfortunately, never got it to work with 
image sequences that e.g. started at #35.
would you mind telling me how this was supposed to work in builds before 
the two paramters you mention were introduced?
glad to hear this is option exists now. will try a newer ffmpeg version 
to implement into our pipeline.

Unfortunately I cannot provide a sample of this video.

I'm sysadmin of a video streaming website, and these videos are uploaded by some of our users. I'd probably get in trouble if I posted the video else where without the users' agreement.

I tried to cut just a few seconds of the video so it was impossible to identify anything, but even -vcodec copy results in a black/blank video.

Any tips would be greatly appreciated!

Some parts should be moved to ffmpeg.texi (for example Codec options only
apply to ffmpeg, same for stream specifiers).

Regarding the color syntax, that's part of a generic file
(doc/syntax.texi) which contains the syntax for several things in the
library/tools, so I'd rather keep that (and although far-fetched you
can empoy the color syntax in ffprobe, e.g. when probing ffprobe -f
lavfi "color=c=red").

Thank you so much for your reply :)

At first, "YUVFilePlayer", I downloaded it from:
http://www.softpedia.com/get/Multimedia/Graphic/Image-Convertors/YUV-File-Player.shtml

let me exactly explain my problem, I have an input stream, mpeg2 or h264, I
want to transcode them (at least transrate). ffmpeg does it well, but I want
to do decoding and encoding separately, I mean:

1) Input.ts -> output1.YUV
2)output1.YUV -> output2.flv and with h264 as codec.

There are several questions here :
1- when a player want to show a coded video (e.g h264), at first it should
decode it, and as I understood the output of decoding is "raw video" (.yuv
file). The player can't display such a file, so it would put it in a
container. Right????
If no, what else?

2- As I understood, we have "raw h264" files that they are h264 coded
streams with no container (I mean mkv, flv, 264 and ... by container). When
we want them to be played, we should put them in a container too. Right???

MY LINUX IS BUSY NOW, I,LL POST YOU MY COMMAND AND IT'S RESULTS AS SOON :)

Thanks ...

Wrong.  The player (I assume you mean YUVFilePlayer, but this applies to  
any other YUV viewer) doesn't invent anything for itself, nor should it.   
A YUV file contains only the pixel data, you have to tell the player  
everything else; the picture size, the pixel format, everything.  It's  
possible that the default pixel format ffmpeg chose (I don't off-hand know  
what that is, and you didn't include the complete, uncut console output  
that would tell us) isn't the same as the player's default pixel format,  
for example.  More likely, is the picture really 720x576 or some other  
video standard?

Also, as Carl pointed out, at this point you have lost the audio.  YUV  
files contain *only* the pixel data, remember.

Um.  Such things exist, but I'll be surprised if you have any of them.

It significantly increases the chances of a random movie player  
understanding them.  It's also the only way to get audio and video  
together.

What about completely splitting the man pages?

man ffmpeg    -> directly ffmpeg-related options
man ffplay    -> directly ffplay-related options
man ffprobe   -> directly ffprobe-related options
man ffserver  -> directly ffserver-related options and config file syntax
man ffcodecs  -> all codecs options
man ffformats -> all formats options
man fffilters -> all filters docs
man ffmisc    -> syntax conventions, etc.

That is what zsh does, and I always found this very practical: when I am
looking for a way to convert the contents of a variable to uppercase, I do
not want to find keystrokes to convert a word in the edited command to
uppercase, several dozens of pages later.

+1 for this, I was talking about that with Stefano the other day, and it
seems it was already proposed a while ago but got rejected for various
reasons.

nit: I'm not sure about using the "ff" prefix for the other manpages. I'd
better use "ffmpeg-", so ffmpeg, ffplay, ffprobe, ffserver, ffmpeg-codecs,
ffmpeg-formats, ffmpeg-filters, ffmpeg-eval, ffmpeg-...

Subject: [FFmpeg-user] FFMPEG BadCursor Error with x11grab
Message-ID: <20120814130017.112350@gmx.net>

I am using XVFB, ffmpeg to do screen capture on a 'headless' server in the AWS cloud on Ubuntu.

I am using this ffmpeg setting (which has worked before on my local machine) 

ffmpeg -i pulse -f x11grab -r 30 -s 640x480 -i :0.0 -b 30k -qscale 1 -s 640x480 -r 15 -f flv capture.flv

in ffmpeg I get:

  X Error of failed request: BadCursor (invalid Cursor parameter) 
  Major opcode of failed request:  142 (XFIXES)

  Serial number of failed request:  14
  Current serial number in output stream:  14

See also: http://pastebin.com/kHPw1S7c

Others have hit this and had relatively minor changes.

But not sure how to patch.

Alternatively we may support both styles
(--enable-monolithic-manpages) but I don't know how much harder would
be to support both styles.

Anyway in both cases we need to move ffmpeg-specific docs in
ffmpeg.texi.

Why?

To play a video, it is certainly not necessary to produce a yuv file.

All players that are relevant on this mailing list (ffplay, 
MPlayer) can play such files.

I don't think this is correct.
The H264 standard defines a raw format (Annex B iirc), but afaict, 
this is not "no container", but "h.264 (raw) container".
(Of course, this is probably just a question of interpretation.)

Then at least post the complete, uncut output of:
$ ffmpeg -i 8714471.wmv -qscale 2 out.avi

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

Post the bottom of config.log, I suspect it starts with

Thanks for the hint, Nicolas. I'll give that a try. Should only need a small 
mod to my "update_ffmpeg" script that I use locally so I don't have to re-type 
my configure line every time. :-)

Yes, please. That would be much easier to work with (from a user who has to 
refer to the man pages quite regularly). 

As a general comment, on the weekend I was trying to figure out how to apply a 
filter (for the first time!) using the new paradigm and figure out the syntax 
for the setpts filter. I was pleasasntly surprised to see how much the man 
page has improved in recent times! Thanks to those responsible. :-)

There is no need for that, and that is something that was not discussed in
the thread you point: man has an include feature. I gave the example of zsh,
it uses it: you can type "man zshall" and get all the man pages
concatenated.

thanks. that explains it. the version used in our pipeline is much 
older. and back then i scripted a workaround for that issue.
as long as there's no urgent need to update i just keep the programs the 
same version to not break things that worked before.
probably, i should give a newer build a try and revamp the whole process 
a bit.
thanks again for the info!

I am using the following command on a Ubuntu 11.10 setup in my home directory:

Sudo git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg

This is what I see on the screen:

Cloning into ffmpeg...

Any ideas what the problem is?

And the error "/bin/arm-linux-androideabi-gcc is unable to create an executable file. C compiler test failed." with:

I got this version of ffmpeg:

How can I compile the ffmpeg with x264?

Thanks

You don't need to use sudo with this command in your home directory.

Perhaps it was a temporary network issue? Have you tried again
recently? If you are having problems using git then an alternative is a
source snapshot available at http://ffmpeg.org/download.html

Message-ID: <CAJDvJJffhg7dUR=VETBqBww_ePyeYpTq2x_P34=NntnvRdcmww@mail.gmail.com>

Hi All,

I trying to create a mpeg video following FFmpeg examples.
Every time* "avcodec_encode_video"* returns ZERO only for the FIRST
frame/packet.

Consequently, after insert more frames i got "*Encode Buffer underflow*" in
Encode function.

------------------------------------
Does anyone know how MPEG encode works for the first frame? E why zero is
return?

PS. in this case, the outbut buffer was not filled.

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

Jorge.

My main problem is that ffmpeg doesnt support HWAcceleration Encoding, so I
want to decode a video using ffmpeg and then pass the output to my CUDA
based code to encode it using GPU. So I think I should do the Transcoding in
two steps as I described in last post.

When .YUV only contains video (pixels), I should have an audio output from
decoding step too, Right?

Subject: [FFmpeg-user] ratecontrol_init: can't open stats file
Message-ID: <1345016717232-4652568.post@n4.nabble.com>

Hello everyone,

I'm trying to transcode some video that I'm getting through rtp and I get
the following errors:

[libx264 @ 0x9d92aa0] ratecontrol_init: can't open stats file

the command that I'm using look like 
[CODE]

Did you do a pass 1? Is the stats file present?

(I believe it is common usage on this mailing list to tell people 
that it is not a good idea to use ffmpeg as root.)

I hope this solves your problem.

Afair, it is commonly agreed here that this produces bad quality, 
and it is unclear if it has any performance advantage on 
real-world hardware.

(Or in other words: "It has only disadvantages.")

You didn't ask for it on your command line, and you didn't give ffmpeg  
anywhere to put it, so no, you don't get an audio output.  If you do  
specify an audio output file and re-encode the video by some other means,  
you may then have problems getting the audio and video synchronised.  I  
really don't recommend this approach.

- What produces bad quality? using ffmpeg as "Hardware accelerated decoder"
and another module as "Hardware accelerated encoder"?
- What do you mean by real world hardware? I want to use "GPU".
-What's your recommendation for speeding up ffmpeg encoding?

Thanks.

Message-ID: <CAAyYaWqf0tUELizt-aUq+o+yS_W1Jwoou8yWh9RYRJaB3dcpzA@mail.gmail.com>

Hi,

I've updated the tutorials originally written by Stephen Dranger
(http://dranger.com/ffmpeg/) so that they work with the latest version
of FFmpeg.

My updated code is here:

https://github.com/mpenkov/ffmpeg-tutorial

Other people might find this useful, so perhaps it may be worth
linking this from http://ffmpeg.org/documentation.html.

Cheers,
Michael

I'm not expert, but it looks ok to me. For example, just doing ffmpeg
-i ~/MyTestJPEG.jpeg reports Stream #0:0: Video: mjpeg, yuvj420p,
384x256 [SAR 1:1 DAR 3:2], 25 tbr, 25 tbn, 25 tbc. A single, still
image is treated as a "video" with only 1 frame.

Is there something specific that looks wrong?

I received this message while trying to configure ffmpeg. 

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

on most distributions you need the DEVEL package
for compile software and not only binary-libs!

I guess the only worry I have with it is that it appears to attempt to
re-encode the (probably still image) as a video stream.  I suppose
ideally it would somehow treat it as metadata, and store it as such in
the output file.

How do you ascertain "black"? What is your command line output when
you play it in ffplay?

Actually, wait a bit on that. MP3s suffer from added encoder/decoder
delays. LAME FAQ talks about it here:
http://lame.sourceforge.net/tech-FAQ.txt

So re-encoding an MP3 just keeps accumulating delays, so it's slowly
getting longer. But three seconds (the first transcode) is a very
large jump... the other ones are more consistent with LAME's delays.

I'm still not clear how to overcome this frame padding issue. Am I right in
saying you need separate paddings for different sequence lengths?

Hello.
I noticed this works:
ffmpeg -rtbufsize 1000k
however this does not (in fact, it appears to silently set the value
to zero [?])

ffmpeg -rtbufsize 1m

is this expected?
Trac worthy?
Thanks.

If u want drop the video (i.e. force an audio only file), use the   -vn   (video none) argument in your cmd line.

I dunno if this makes a difference, but did you try "1M"? In metric
prefixes, m = milli (10^-3), but M = mega (10^6). I'm not sure if
ffmpeg takes this into account or not, but it's worth checking.

Message-ID: <1562170311.262994.1345065291454.JavaMail.sas1@172.29.251.236>

Hello

I am converting a video from different formats to flv and mp4. In both cases I face many cases where duration of generated video is longer (never shorter). The difference is quite considerable for me (1-2s for 90s input).

Command example:
ffmpeg.exe -i "Dolphins_720.wmv" -ar 44100 "Dolphins_7202_TMP.flv"

When I lower the bitrate then the difference shrinks, however, never beneath 1s (for 90s input). Unfortunately that is not acceptable for me. Do you know how can I "force" the ffmpeg.exe to maintain the same duration?

Regards
Dawid

I have created a defect for this problem, where you can find more input (check out the comments also).

As Carl said, please provide the complete, uncut console output of
your command (ffmpeg.exe -i "Dolphins_720.wmv" -ar 44100
"Dolphins_7202_TMP.flv").

Also, I'd be interested in seeing the complete, uncut console output
of ffprobe -show_streams ("ffprobe -show_streams Dolphins_720.wmv" and
also "ffprobe -show_streams Dolphins_7202_TMP.flv").

That does appear to work, thanks.
I guess I didn't know that in metric little "k" means kilo but big M
means mega. Weird.

Actually the proper metric suffix for thousands is cap K, but using 
little k is popular and is doesn't interfere with the divide-by suffix 
so it's allowed more often than not.

Actually, it's little k. See http://physics.nist.gov/cuu/Units/prefixes.html

Or if you want a really official source, see NIST Special Publication
330, 2008 Edition at http://physics.nist.gov/Pubs/SP330/sp330.pdf

Or for a non-US version, the prefixes agreed upon in Resolution 12 at
the 11th Conf?rence G?n?rale des Poids et Mesures at
http://www.bipm.org/en/CGPM/db/11/12/ (full PDF of the official
current SI brochure can be found at
http://www.bipm.org/utils/common/pdf/si_brochure_8_en.pdf
(particularly, see page 121)).

Sorry, I just got interested in this stuff :)

(You cut too much.)
Passing "the output to my CUDA based code to encode it using GPU" 
is assumed to produce worse quality than using x264.

I would expect a modern CPU to encode as fast as a GPU.

FFmpeg does not encode h264, x264 has many options that allow 
to choose a trade-off between speed and quality.

Any comments?

Subject: [FFmpeg-user] moving from FLV to MP4 container
Message-ID: <DUB111-W55A5986D33F84B4B44803CFDB50@phx.gbl>


Hi,

I have an FLV file which plays correctly. When I put it in an MP4 container using:

ffmpeg -i video.flv -acodec copy -vcodec copy video.mp4

video.mp4 does not play properly in Media Player Classic Homecinema 1.3.1264.0 (MPC). When I double-click a video file in Windows Explorer it usually begins playing automatically in MPC; this file does not. If I click on the "seek bar" to jump to different parts of the video, it plays, but the audio and video are out of sync. A large part of the video is missing from the beginning: I can hear the audio from the beginning of the original file playing while I see video from several minutes into the original file. No video seems to play at the end of the file.

When I stop playback by clicking the 'stop' button and then restart playback by clicking the 'play' button, the video plays at about double the correct frame rate.

Does anyone know how to make this conversion properly? I've noticed the following oddities in the properties of the FLV and the generated MP4, in case it helps:

When I use ffmpeg -i video.(flv | mp4), the tbr and tbc values of the video stream are the same in both files, but the tbn is 1k in the FLV and 10000k in the MP4. Why are they different?

There is an fps value listed for the video stream in the MP4 but not in the FLV.

Why does ffmpeg say below that it is estimating the FLV duration from the bitrate? Should the FLV explicitly state the duration?

In the output below which shows the properties of the MP4, why is the fraction used to approximate the container frame rate of 23.98 different from the one in the properties of the FLV (20,000,000/834166 vs. 24000/1001)?

Why are the bitrates of the streams lower in the MP4, given that they were copied from the FLV?

Why don't the duration and start values match?

These are the properties of the original file:

Thank you for your reply and suggestion.

A patch to what?  The documentation.html page isn't in git (unlike
some other pages, like faq.html, that are in ffmpeg/doc).  Similarly,
the tutorials themselves are also not in git.

Or are you suggesting that the patch contains the entire tutorials?

Please clarify.

There's two repositories: one for the website and one for ffmpeg. The
website git is at git://ffmpeg.org/ffmpeg-web where documentation.html
comes from (though the actual html gets generated; the source is in
src/documentation.

If it also fails for current git head, please provide complete,

If what you need is a high-quality version of the file

$ ffmpeg -i file.lvf -qscale 2 out.mpg

Subject: [FFmpeg-user] stream segment durations not exact length
Message-ID: <08513DDE83F9427DB0E0E4C1734EC572@gmail.com>

Hi guys,

I've been futzing around with segment to split a video into HLS-compatible segments of 10 seconds each, but I'm noticing some odd behavior. In particular, some of the segments generated have varying lengths from 2 seconds to 17 seconds. I've tried playing around with segment_time_delta and force_key_frames to make the segments as close to 10 seconds as possible, but it doesn't seem to be working out so well. Does anyone happen to know something about this?

Thanks,
Young

Hello Roger, 

> How do you ascertain "black"? What is your command line output when
> you play it in ffplay?

I don't compile ffplay on my encoding servers so I can't say. I used winscp to copy the file over to my desktop and opened it in VLC 1.1.8.

This morning I received another sample with the same behaviour, and this time I can make the file publicly available.
I wasn't able to upload to your ftp server, so it is available here: http://video.linuxdataflow.org/wmv3_sample.wmv and http://video.linuxdataflow.org/wmv3_sample.txt

I am getting more and more of these videos files - I suspect they come from a recent winphone.

In case here are my ./configure options:

./configure --prefix=$INSTALL_DDIR --enable-shared --enable-nonfree \
                --enable-gpl --enable-pthreads  --enable-libopencore-amrnb  --enable-decoder=liba52 \

What value did you pass to -force_key_frames? It needs a -
potentially very long list of 0,10,20,30,40 ...

The sample decodes fine with ffmpeg here.
Since it contains more than one video stream, you may 
have to use -map (depending on which video stream you 
want to encode).

If you need more help, please do not hesitate to ask, 
but please also provide a failing command line together 
with complete, uncut console output on the mailing list.

Turns out you can compile libx264 and specify to use "windows threads"
(as well as ffmpeg).  With libvpx you still need it though (and
something like the above did work).
Anyway, the latest zeranoe builds have switched temporarily to using
"just windows threads" until we can figure out what's wrong with
pthreads (as a work around).

"FFmpeg user questions please post full console/command lines"

Thoughts?

Arg my bad. I feel very stupid. I don't know how I missed that second video stream.

So you're using libav?
Does ffprobe -show_packets show them all as i-frames?

There is a "thumbnail" filter:
libavfilter/vf_thumbnail.c
http://ffmpeg.org/ffmpeg.html#thumbnail

But I think in general one just resizes (scale filter)
http://ffmpeg.org/ffmpeg.html#scale
to get a thumbnail.

Oops the 3 seconds one was a typo :)

Ok with .wav it seems to keep consistent timings.

However, using lame "straight" (lame.exe) results in the following timings:

lame1:  00:00:53.28
lame2:  00:00:53.28
lame3:  00:00:53.28

(and the files stay the same size, so maybe lame has fixed their
problem since then?)

This is using the same version of lame that ffmpeg is compiled with.
Any feedback?
Thanks.

Not yet, but I have recently added "write an EDL filter" to my TODO list, so
it may come in due time.

No, it's still an issue in LAME.

> This is using the same version of lame that ffmpeg is compiled with.
> Any feedback?

LAME is kinda special. I just did some tests (and I plan on contacting
the LAME list about this), but here's what I've found: LAME adds the
delay, just like all MP3 encoders do. BUT, it also has the special
ability to skip this delay when it reads an MP3 file (or at least it
skips the delay it added; dunno if it works with MP3s encoded with
another encoder). So if you do lame in.wav out.mp3 and open it with
Audacity or something, you'll see the delay at the start (there's also
about ~277 samples missing at the end... I'm trying to get feedback on
this from the LAME devs). However, if you then do lame --decode
out.mp3 out.wav and open out.wav in Audacity, the added delay to the
beginning is gone and the missing ~277 samples are back at the end
again.

So it looks like LAME is the only tool that properly reads LAME
output. I suspect that if you select the libmp3lame codec for the
decoder (and don't use FFmpeg's MP3 decoder) it'll go away. But if you
use another MP3 decoder, it doesn't do whatever magic LAME does (so
the delay is still there and the missing samples are still gone), the
delay just gets accumulated.

Like I said, I'm trying to get feedback from the LAME devs on this (I
just came across it this week). If anyone else has any input on this,
I'd be happy to hear it.

Lies. Sorry, I was wrong :)

I think FFmpeg's MP3 decoder is to blame for the missing ~277 samples.
I've just checked things, and FFmpeg's decoder is missing the last
little bit of the audio. However, when I used libmad or MainConcept's
decoders, they decoded the full song.

Also, there's no libmp3lame decoder :)

But I still stick with what I said about LAME auto-skipping the delay
when it decodes an MP3.

I'll go ahead and open a trac ticket regarding the missing ~277
samples. The increasing length though... I think that's just due to
the inevitable delay accumulating, and I don't know if it can be
reliably skipped (I'm not sure how LAME does it though, so maybe it
can?).

Wow, I am just all sorts of wrong today. Looks like I was using an
older version of FFmpeg (thought it was git head, turns out it's a few
months old), and it indeed had a buggy mp3 decoder but it's been fixed
in current git head.

I've looked at it more: The lame technical faq explains: "LAME embeds
the amount of padding in the ancillary data of the first frame of the
MP3 file. (LAME INFO tag). The LAME decoder will use this information
to remove the leading padding of an MP3 file." It's really out of date
(12 years old), because it also says "Modifications to the decoder so
that it will also remove the trailing padding have not yet been made"
which, I've found, is wrong, because since then those modifications
have been made and it now skips this trailing padding.

FFmpeg parses this lame tag now and skips the leading padding, but it
does not skip the trailing padding (I don't know how it would...),
which is why using ffmpeg accumulates length and lame does not when
re-encoding the file.

That was fun :)

Roger -

Have you had any luck with this issue ?  I have a similar issue where I am
streaming content from device and based on the content I would like to shift
the overlay to another location.  I have been looking at filters but, I have
not settled into a particular solution.

Thanks,

Subject: [FFmpeg-user] Change coordinates of image overly
Message-ID: <1345068615123-4652601.post@n4.nabble.com>

So, I have a problem where I need to change the position of an image overlay
based on the values that I am being passed.  At this point, I am streaming
data from a device that, in this case, is watching a bouncing ball and there
is a process that is sending me x,y coordinates of the ball (i.e. its'
center).  I need to take those coordinates and shift my image overlay based
on them.  I have been looking at filters.  The main problem, from what I can
see, is that the overlay is specified at the being of the stream.  For
example, 

ffmpeg -i rtsp://0.0.0.0:9998 -i overlay.png -f ogg -filter_complex
'overlay=20:main_h-overlay_h-20' output.ogg

With that command I am able to see my overlay perfectly on the ball but,
once I the content streams I need the overlay to shift accordingly.

Any ideas ?

Thanks, 
Dennis

Subject: [FFmpeg-user] Multiple filter files
Message-ID: <1345127307047-4652628.post@n4.nabble.com>

I've inherited a project that uses ffmpeg and I'm a bit confused by the
command line being used:
What does it mean when multiple preset filter files are specified?

For example, if the following command line is issued what are the actual
results (note that the preset filter files have several overlapping
arguments):

ffmpeg -acode aac -ac1 -ab 48K -strict experimental ?vcodec libx264 ?pre
libx264-slow.ffpreset ?fpre libx264-ipod640.ffpreset ?b 450K ?threads 0
filename.wmv

Thanks,
Owen

Hi,

Is it possible to make ffmpeg listen to a local UDP port for RTPs and
automatically create MP4 out of them ?

Thanks,

Config says:

./configure: 1: yasm: not found
yasm not found, use --disable-yasm for a crippled build

Either install yasm, or "--disable-yasm for a crippled build"

You raise a good question.
Question 1) is there any concept of "dynamic parameters" or "dynamic
variables" in filter graphs?

You can tell by "running" it and checking the output.  My guess is
that you could get some variables from one, some from another, but the
latter would override...

I'm not exactly sure, but when I run Apple's segmented against the video, it consistently produces segments that are 10 seconds.

That's basically what I passed through to ffmpeg. I was thinking of trying to force an intra frame per second to see if that helps.

From Mailman: "This description is used when the mailing list is listed
with other mailing lists, or in headers, and so forth. It should be as
succinct as you can get it, while still identifying what the list is."

It would be nice for users to be more aware of the value of providing
the command and console output, but I think your suggestion is too
verbose to be added as the description. However, I never did like the
"and RTFMs" so I removed that.

Instead I updated the info page (the link in the signature and where
users subscribe) to include our motto.

I've done this now, and it seems to have worked.

Do you have an idea of why the duration and bitrates are still different?

duration:
FLV: 46:39.67    MP4: 46:39.66

overall bitrate:
FLV: 336 kb/s    MP4: 335 kb/s

video bitrate:
FLV: 253 kb/s    MP4: 246 kb/s

audio bitrate:
FLV: 82 kb/s    MP4: 79 kb/s

I've also noticed this difference in the properties displayed by ffmpeg -i video.(flv | mp4):
FLV:
Input #0, flv, from 'video.flv':

MP4:
[mov,mp4,m4a,3gp,3g2,mj2 @ 0228bf20] multiple edit list entries, a/v desync migh
t occur, patch welcome
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'video.mp4':

Why are there multiple edit list entries, why might they cause a/v desync to occur, and how can I reduce them to one?

Victor

Please provide your actual command (this one is missing an input and
some options are using ? instead of -) and the complete, uncut console
output.

Message-ID: <45C2491B7E8B4D17ABBA7B9183803C91@PCvanRiven>

Dear ffmpeg developers,


For a video analysis application, we use ffmpeg to stream video to stdout as
raw rgb values:
    ffmpeg -i ... -f rawvideo -pix_fmt rgb24 -

This works perfectly fine on Linux, but on Windows we run into performance
problems on 1280x544 and higher resolution videos.

I did some benchmarking, and it seems that Windows has a significant
overhead per write call for stdout / piping. These are my results of two
processes communicating with stdout --> stdin:
    writing batches of 16 bytes: 4MB/sec
    writing batches of 1024 bytes: 170MB/sec
    writing batches of 4096 bytes: 260MB/sec
    writing batches of 65536 bytes: 980MB/sec

At 1280x544 @ 24fps, using RGB8 as output means we're moving around
48MB/sec. I suspect that ffmpeg is writing relatively small batches of data
to stdout. As said, it works perfectly fine on Linux, but unfortunately
we're not as lucky on Windows.

If my calculations are correct, then 1920x1080 @ 30fps would mean we'd need
a throughput of 177MB/sec, for which 4K writes seem enough, although a
higher margin could be desirable, as CPU-usage on I/O climes significantly
with a higher write call rate.

I hope buffering stdout write calls could be integrated into ffmpeg, as it
would allow us to deploy on Windows too. Thanks for your time!


With kind regards,
    Jason Anders

Giving uncut command line and console output might help us tell you.

My guess is that since you're not encoding it to a new codec, it
really can only split on key-frames (you might be able to tell by
using ffprobe -show_packets input).

I've heard of this before, so you're probably right.
Just how to buffer the output I have no idea.
In the meantime you could try writing to a windows named pipe, or to a
file.  Or submit a patch :)

Subject: [FFmpeg-user] some files unplayable in WMP
Message-ID: <CAL1QdWcz+SV+vM_FfRAb3Kdb3vdYZLKbZzGJio0nC7-iM4Xrrg@mail.gmail.com>

Are "not playable in WMP" errors worth reporting?

Example:
$ ffmpeg -i sintel.mpg -vcodec copy -acodec copy out.avi

produces a file that has working audio but not working video in WMP
(sintel.mpg itself plays fine, out.avi plays fine in VLC).

$ ffmpeg -i sintel.mpg -vcodec copy -acodec copy out.mpg

produces a file that has working video but no audio in WMP (and also
no audio in other players, see my next post).
Cheers!

It seems to succeed...

However, the output doesn't seem to have "playable audio" for mplayer or VLC.

If I use

$ ffmpeg -i sintel.mpg -y -vcodec copy -acodec copy yo.avi

The file yo.avi is playable.

In fact, if I convert it from "bad" .mpg to an .avi (with -vcodec
copy...), the resulting file also works fine.  So ffmpeg is able to
read the audio ok.
MediaInfo seems to reveal it having an audio track.
Any ideas?
Thanks.

Are the files the same size? Which of these has a more "accurate" bitrate then?

I'd like to update this RFE to status: discard :o)

It turned out that reading stdin is dog slow when trying to do this:
    read(handle, buffer, w*h*3);

I rewrote it to read from stdin in batches of 64K, and-a-bit until I get a 
full frame. After this minor change I could read frames in 8ms, as opposed 
to the ~330ms I had earlier.

Thanks for your time, I'll crawl back to where ever I came from!

If you need very high throughput, you should probably not be using pipes to
forward raw video data anyway. Using the API instead of the command-line
tool would be much more efficient.

Hi every one, I have only one processor and it tooks time to add logos. So
some questions comes to my mind.
I apprecitate any suggestions to improve this task: theading?, enable
GPU?..etc.
Is better with a good graphic card?.

Thanks and regards

more processors :)

Also if you give us a full uncut console/command line we might be able
to help more.

> Is better with a good graphic card?.

Nope, ffmpeg doesn't really use them (yet) at least.

Hi Roger, more processors is out of the question at this moment.
Actually the console command is quite simple, and the output it is quite
straightforward

Command line:

ffmpeg -loglevel error -i video1.avi -vf "movie=logo.png [logo]; [in][logo]
overlay=W-w-10:10:1[out]" -vcodec libx264 -acodec libmp3lame -b 1400k -b:a
192k outlogov1.avi

Sum it up:
- a good processor?
- RAM requirements? 2gb more?

Thanks

RAM won't help I doubt (as long as it's using 100% cpu...ffmpeg tends
to not use too much RAM).

Since you're using libx264 you could use
-preset ultrafast (makes the files larger, but faster encoding)
or use mpeg4 for the video codec if that's an option.

Why AVI and not MP4 or MKV? AVI is generally not recommended with H.264.

Current x264 presets in descending order of speed are: ultrafast,
superfast, veryfast, faster, fast, medium, slow, slower, veryslow,
placebo. Ignore placebo as it is a joke and a waste of time. Typical
recommendation is to use the slowest preset you have patience for. If
it is too slow use a faster preset.

You asked about threads earlier but it was cut in a previous reply.
Recent ffmpeg uses "-threads 0" with libx264 by default, IIRC, so you
don't need to mess with that option. The value of "0" confuses some
people, but to simplify consider it to be "auto" and not "no threads".

Third I miss to respond something, the files are in avi format and it quite

Thanks for the tip, I am very clueless and new using ffmpeg.

Why is not recomended avi files to set them to h264?.

Hi,

I'm trying to remux a live rtmp feed to mpegts

The problem is that the bitrate slows down after a while (30mins, 2 hours, depend) and ffmpeg stops :

Here is the last lines of log, the bitrate was at 3.4Mb/s at beginning :

Hi all,
I am calling 'ffmpeg' from PHP to encode a video.here id how I am calling. exec(''ffmpeg -i inputfile outputfile 2>result.log");
I am trying to redirect stderr to a text file.ProblemI was expecting only errors to be written to log file but the entire console output is being written to file.Is there a way to only display error with ffmpeg.How can I find a encoding failure by looking at the console out put.
Please help me.

Thank you,
Thanks a lot for your support.

Look into the -loglevel option. If you set it to "-loglevel warning"
or "-loglevel error" you'll just get messages with a minimum priority
of warning or error (respectively).

some ffmpeg- command
then I check for  $?

see this: http://tldp.org/LDP/abs/html/exit-status.html

I had the same problem, I am not able to detect an exact error, the most I
achieve was identifying it  according to the command I am using.
I do the following:

Could you also post your beginning of the console output, and command line used?

Also can you point us at a stream that reproduces the problem?

I think -loglevel 'error' is working for me.I am also using -report to make output of the command to a file .
Thank you all.

I was using the  following command
"ffmpeg -i <input> -v 'error' <output>"
the terminal was empty till the encoding is finished. I again tried out with a non existing file like this
   "ffmpeg -i <nonexistingfile> -v 'error' <output>"
      I got an error < No such file or directory>.  You may get empty if no error is found while encoding.I will be trying this in real time from a while from now.I will post to same thread If I found any issues.
Sorry if it is too early to post as 'It worked'.

Thank you.

Were you 1) reading from stderr (and not stdout) and 2) getting errors
(if there are no errors, you'll get... no errors)?

Hi,

I want to do something as given below:

I have two ?video stream 'x' and 'y' and I want to combine every picture of video 'x' and video 'y' in to ........something like ................half picture of 'x' stream and half picture of 'y' stream as a single picture.

for example,

x and y are input videos and z is the resultant video stream..............

x1 x2 x3........ ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?x1.5 ? x2.5 ? x3.5
pictures in both the stream ? ? ?:- ? ??

y1 y2 y3 ........ ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? y1.5 ? y2.5 ? y3.5
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? -----------------------------
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?z1 ? ? ? z2 ? ? ?z3


Basically, I want to combine picture of two videos in to resultant video. So if any body knows this thing how to do this then it would be really a great help.

That will only capture stdout, not stderr. stderr is where the errors
are reported.

OK, I see how a different container format would change the size of the file and how this would change the overall bitrate, but the duration should be identical because the audio and video data were copied from the FLV to the MP4. The audio bitrate and the video bitrate should be identical for the same reason.

I don't have any console output as the project runs inside a web-page and the
output is lost.

The command-line is built inside an asp file and is concatinated from
several strings. The emdash and regular dash are byproducts of windows cut
and paste :-(

The command line, more exactly, is the concatinated string:
converter + "\\ffmpeg.exe -i" + strPath + "\\" + originalVideoName + " -s "
+ videoDimension[0] + "x" + videoDimension[1] + " -acodec aac -ac 1 -ab 48K
-strict experimental -vcodec libx264 -fpre " + converter +
"\\presets\\libx264-slow.ffpreset -fpre " + converter +
"\\presets\\libx264-ipod640.ffpreset -b 450K -bt 450K -threads 0 " + strPath
+ "\\" + newVideoName;

Where converter is the path to the ffmpeg exe and strPath is the path to
where the videos are stored.

Libx264 is doing fine with win32threads. However, I did not like the
idea of using 2 different kinds of threading methods in the same
executable, so I chose for libvpx 1.0.0. Maybe it is not up-to-speed,
but I wanted to have libvpx in my executables allthough I do not have
plans to use it yet.

Fine. I will do some speed tests, from 50i PAFF interlaced files to
x264/faac. I will follow-up if remarkable differences occur.

I'm sure it'll be supported at some point (either through a 3rd party
library or though ffmpeg's own code), but HVEC/H.265 won't be
finalized until early next year, so there's still a bit of time to
wait anyway. Exactly when ffmpeg will support it, I don't know, but I
wouldn't expect anything until HVEC has actually been finished.

As the Zeranoe builds do not have libfaac (yet?), I had to test with
x264/aac. My own builds were slightly faster than Kyle's but nothing
special: 2 seconds on a total of 130s (32-bit) or 115s (64-bit). Kyle's
latest on its turn was 2 seconds faster than Andy's build of 20120710.

Interestingly enough, Andy was faster than Kyle in converting to
WMV-format (and on par with my 64-bit builds).

There has been some discussion on the status of Libfaac. Does that
effect Zeranoe's builds?

Jan

BTW: mencoder-r33986 is still faster on the same files.

Just wanted to mention that faac and fdk-aac will never be in any distributed
binary.

They are considered non-free and therefore you have to compile ffmpeg with the
option --enable-nonfree, which means that the resulting binary is not
redistributable.

Yes you basically have to build your own ffmpeg that has them included.
here:
https://github.com/rdp/ffmpeg-windows-build-helpers
Is my helper script that cross compiles (optionally) with them
included.  Not faac since it's low quality though, isn't it? :)

I guess this is possible, given that other formats like "wav" can

Hi,

I can access other web sites but connecting via ftp to
upload.ffmpeg.org gives me:
ftp: Can't connect to `138.195.131.196': Operation timed out
ftp: Can't connect to `upload.ffmpeg.org'

Is the server down at the moment?

As a follow-up note (to myself, apparently):
$ ffmpeg -f dshow -i video=screen-capture-recorder  -vcodec libx264
-an sintel2.mpg

produces a file unplayable by WMP or lacking video in VLC...

Also I assume that you have "extra idle" cpu at the time the problem
occurs, and that if you restart it, it goes back to full speed?
Also what OS? (a preview question to "have you tried librtmp TRUNK?")

>From everything that I have been reviewing;  It does not seem like it is
possible, with existing filters, to have dynamic parameters.  That said,
there is a link on ffmpeg "HOWTo ffmpeg filter" that describes how you can
create a custom filter and it provides a wiki with a small example.   I
believe that if I can start with that example you look at the built-in
overlay filter I will have a good shot at making it dynamic.  The key method
you should focus on is draw_slice().  This method receives each frame and I
am guessing is the best spot to make a call to retrieve the parameters.

Could you also post your beginning of the console output, and command line used?

Also can you point us at a stream that reproduces the problem?

Hi, Wagner!

I have the same problem, but it is not resolved by converting srt to sub.
Could you send command which you entered.
And what version of ffmpeg was used?

Thanks in advance.

Message-ID: <502E3E55.8030308@infibeam.net>

Hello,
     I am installing ffmpeg following the steps given in the link 
http://www.kdenlive.org/user-manual/downloading-and-installing-kdenlive/installing-source/installing-ffmpeg. 
I got the following error.


ERROR: libmp3lame >= 3.98.3 not found

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


I was looking for lame version 3.98.3 on 
http://sourceforge.net/projects/lame/files/lame/ but its not there. 
please if you can see the I am following steps are correct. If not, 
please guide. Hoping for your needful.

Sorry, but "not work" is not an acceptable description of the problem.
How is anyone supposed to know what the problem really is when you
don't actually include the actual error message? If you want help, then
please spend more than just a few seconds to ask a detailed question
including your complete ffmpeg command and the whole, uncut console
output.

Subject: [FFmpeg-user] Input to ffmpeg from Sony HDR-XR550 video camera
Message-ID: <502F35D1.6040703@netmaster.dk>

Hi

I have a setup where I get input to ffmpeg from dvgrab through a pipe, 
ie. `dvgrab -format dv1 - | ffmpeg -f dv -i - . . . `. This works fine 
for my low budget Canon DV camera.

This way I work with the video using ffmpeg as the video is recorded by 
the camera.

Now I have a much better Sony HRD-XR550 HD camera and I simply can not 
find a way to get the output from the camera into ffmpeg!

Any ideas would be very much appreciated!

Thanks

Message-ID: <CAATPF_T7++dt6EYGStq5Garc1GuGdPx_13wt4rs7ErkQB5FTpA@mail.gmail.com>

Hello Friends,

I was trying to use ffmpeg as container format parser and use hardware
codec of embedded board.

The problem is embedded decoder must need to pass header data which
hardware used to initialise it's system.

I believe FFmpeg also search for header data in file to initialise it's
codec.

Is there any way to get that header data from ffmpeg to pass to hardware
decoder ?



Here is some use case.

I use libavformat to parse a raw h264 file this file provided with demo
board and they have them own parser for h264 raw.

FFmpeg first packet size is 11733. which includes header togather.

Where demo parser first packet size is 21 and second packet size is 11712
where 21 + 11712 = 11733.

If I pass all together hardware decoder is not working. Besides not all
file first frame would be header data & different codec have different size.

It would be great if there would be a api to get header data with size.


Waiting for some information.

Hello All,

 

It has been quite some time since I last updated FFmpeg somewhere in 2009. A
recent project requiring AAC encoding and Lagarith decoding support (which
weren't available in the default builds at the time) got me to look at
what's available now.

 

And how pleasantly surprised I was!

* AAC encoding has been added

* Lagarith decoding has been added

* Automated _daily_ builds have been added (thank you Ramiro for those in
the past)

* Many other things

* And everything I tried so far just _works_. Apart from updating the syntax
of command-line options (mainly x264), the new version just slotted in and
worked. In some instances even faster.

* Documentation is more up to date than before

 

All told I get the impression of an increasingly polished and professionally
run project, into which large amounts of concerted effort has gone over long
periods of time. As for my experience, the daily build I downloaded just did
the job without even breaking a sweat.

 

I want to sincerely thank each and every one in the FFmpeg community for
their contributions, for making it such a success, and for helping me make
such a success of my project. I am sincerely grateful for your efforts.

 

Normally, in circumstances like this, by way of token contribution from my
side I would have submitted reports on whatever bugs I came across. In this
case I have to disappoint you. There were none and you will just have to do
with the Thank You J.

 

Kind regards,

Francois

You just didn't find them yet;-(

Two additions:
Please note that the native aac encoder is known to produce 
worse quality than the best encoders available.
And consider looking at http://ffmpeg.org/donations.html ;-))

Does it play with MPlayer / ffplay?

I don't think WMP supports h264 in mpeg-ps.
(But again, if I am wrong, please share a working 
sample and report the problem!)

Google sponsored decoder development for one of 
FFmpeg's forks in Google Summer of Code.

It is likely that the decoder will hit FFmpeg soon, 
but I wonder if you already have a sample to test 
decoding?

Subject: [FFmpeg-user] Cutting video at i-frames to avoid recoding
Message-ID: <5030096D.2090300@gmail.com>

Hi

Context: I have some home movies of animals doing cute things, where I left the 
camera running so a good portion is garbage. I want to cut out and keep the good 
parts, but I don't want to re-encode because then it wouldn't feel like the 
'original' footage, as it were. I know that you can't cut a H.264 movie just 
anywhere, because the output file has to start with an i-frame.

I know that FFmpeg can "-vcodec copy" and I know that you can also set "-ss" 
start time and duration; but I don't know if you can do both at once, and if you 
can, how does it behave? (I'm thinking that the GOP could be as many as 300 
frames, and I believe FFmpeg 'only goes forwards' so it is not reasonable to 
think that you could specify a start time and expect it to go BACK in the stream 
to the previous i-frame; that's just not how it works, right?)

So my basic question is: how can I cut a h.264 movie without recoding anything, 
specifying a start and stop time?

It would be perfectly acceptable if the first frames were simply grey, 
containing only the differences - I know this is possible because sometimes on 
youtube, you see videos that have been cut this way; here's an example:
http://www.youtube.com/watch?v=SwRFoxgEcHc
(watch just the first few seconds "are about to perform" before an i-frame comes 
along and clears things up).
It would also be acceptable for FFmpeg to count to the specified time, then wait 
for the next i-frame to arrive before doing the stream copy (I can find my GOP 
and ensure that I add at least that time prior to the cute parts).
It would also be acceptable if I had to use a tool like "FFprobe" with "show 
frames" to locate the exact time of an i-frame, and then use that as my "-ss" time.

Thank you for any insight into this. I know it's similar to Gregory1234's 
question, but I don't think that thread really came to a conclusion.

I don't think skipping I-frames is a good idea if you want a decent
footage quality (much better to re-code the file in that case).

You may have a look at the segment muxer, it may be useful depending
on what you want to exactly achieve.

Instead of stop time, you specify the duration of the clip you want.
Maybe try this:
ffmpeg -ss [start time] -i [input] -t [duration] -c copy [output]

Re-coding is unacceptable as a matter of principle; this is my 'stock footage', 
i.e. raw (as shot) out of my camera. I think movie editors refer to it as 
"assets". My objective is to cut out gigabytes of unwanted stuff, to save disk 
space; the stock footage must remain "original".

What I'm saying is that if the first few frames are trashed, it doesn't matter 
to me, because those seconds would never make it into a movie production anyway.

> You may have a look at the segment muxer, it may be useful depending

Actually, that could be an answer. Thank you for giving me something to google 
for "segment muxer" - sometimes, knowing what to look for is all the help a user 
needs - LOL.

It certainly looks like it splits files at i-frames, which is what I need. I 
could split my files into 10s segments and then delete ones which contain 
nothing useful. It would mean that I'd be loading multiple segments into my 
movie editor, but that's probably acceptable.

I wondered if I could concatenate the segments I want back together again, but 
I've been reading the old thread started by Acer Yang on 2012-02-12 and it looks 
like it's hard to get the "moov" atom to show the right time.

Thanks for the start, Stefano, if anyone else has any other ideas...

Unfortunately there are no errors in the output you posted.
(They would start with "error" instead of "warning".)

Whenever you want to report an error during make process, 
please do the following:
Run make (it fails), run make again (fails again).
Then run "make V=1" and post the configure line that you used 
and the complete, uncut output of that last make run ("make V=1").
Never post complete, uncut output of the first make call.

Hmm, just realized that there is a 100MB limit. The file I have to
upload has 356MB (24 seconds AVC-intra) and I don't have access to the
camera it's from so I cannot produce a smaller sample. I guess I'll
have to wait until the ftp server is up again or are there
alternatives?

It should be easy to cut your sample.
Do you want to upload an additional sample for ticket #524?

(Or in other words: Complete, uncut console output missing.)

If I connect to camera using USB then the harddisk on the camera is mounted 
as /media/disk. 

Here is type of the files recorded by the camera: 

ffmpeg -i /media/disk/AVCHD/BDMV/STREAM/00714.MTS

This way it seems to be easy to get the video files on the camera to my 
linux computer. 

BUT, I want to get the file on the camera to my linux computer as the video 
is being recorded. 

Is that possible?? 

Thanks

You used "ffmpeg -f dv -i -" to read from your old camera, 
that would be "ffmpeg -f mpegts -i -" now.
(I don't know if the camera supports what you want.)

Try http://www.filehosting.org/ it has no limits per file size. Files
are stored 20 days

Experiment? You came up with some pretty decent-looking suggestions
yourself. I suspect your concern is whether ffmpeg will ensure that start
time and duration coincide in some way with I-frames. With utilities like
Avidemux (and VirtualDub with an H.264 decoder) you can see where the
I-frames are in your source footage. Then you can run some test "copy
encodes" with ffmpeg and evaluate results?

Failing all else with ffmpeg, Avidemux should do the job for you. Manually
set the cutting boundaries at I-frames.

FFmpeg by default only seeks to key-frames.
(MPlayer developers do not like this and set a 
flag to allow to seek to - grey - non-key frames, 
but I am not sure this can be done from the 
command line.)

Iirc, -t does not always work with -c copy, 
but this is of course how it should work.

So I tried this using a recording from ITVHD made with vdr:


ffmpeg_g -i 
/media/videoPIII/video/The_Break-Up/2012-08-19.00.22.191-0.rec/00001.ts -map 0:0 -vcodec copy -map 0:2 -acodec copy -map 0:3 -scodec copy -ss 0:04:57.31 -t 00:32:30.850 Break_up_test_1.ts


Complete output at the end - so far - no errors. FFmpeg used to complain in my memories when trying to remux subtitles. But even mediainfo showing that there is a subtitle stream, I cannot visualize it neither with mplayer, vlc or xine or demux it with ProjectX (which is possible using the uncut original recording).


Here are the outputs:

You mean you want to stream the video directly from the censor into
your screen? Not grab the recorded files from the storage...

Do you have a recommendation to do that without modifying
characteristics of the file other than to modify the atom offsets in a
hex editor? That would be appreciated.

> Do you want to upload an additional sample for ticket #524?
Other than that the file is also AVC-Intra in mov it is different in
several aspects (it's not Avid-related, it's got a different fourcc).
My plan was to submit a bug report with the file, command line,
console output (which is ready but not submitted because I could not
upload the file) and have some of the devs decide whether it's a
duplicate, if that is OK:

If the policy is to first post bug reports here, I will do that it
would be nice to document it in http://ffmpeg.org/bugreports.html,
other than that, see above.

What's your recommendation? Wait for ftp server to work again, use
http://www.filehosting.org/ as suggested by anonymouzxx (thanks) or
cut the file (recommendation pending)?

What kind of subtitles do you have to start with? And what sort of "add" do
you need (in other words: compatible with what software)?

Can you show what you tried?

This is probably too old. There was a few features added in the last two
weeks.

Hi all,

 

I try to decode an AAC latm stream with the latest ffmpeg (it?s from
zeranoe).

According to FFProbe everything is fine with the stream and the ffmpeg build
(exe) can play the stream without errors.

 

ffprobe.exe aac_dump_ref.aac

  Duration: N/A, bitrate: N/A

I try to pass this stream to :

 

    AVCodec *codec;

    AVCodecContext *c= NULL;

    int len;

    FILE *f, *outfile;

    uint8_t inbuf[AUDIO_INBUF_SIZE + FF_INPUT_BUFFER_PADDING_SIZE];

    AVFrame *decoded_frame = NULL;

 

    av_init_packet(&avpkt);

 

    printf("Audio decoding\n");

 

    /* find the mpeg audio decoder */

 

    codec = avcodec_find_decoder(CODEC_ID_AAC_LATM);

    if (!codec) {

        fprintf(stderr, "codec not found\n");

        exit(1);

    }

 

    c = avcodec_alloc_context3(codec);

 

    /* open it */

    if (avcodec_open2(c, codec, NULL) < 0) {

        fprintf(stderr, "could not open codec\n");

        exit(1);

    }

 

    f = fopen("ref.aac", "rb");

    if (!f) {

        fprintf(stderr, "could not open\n");

        exit(1);

    }

    outfile = fopen("out.raw", "wb");

    if (!outfile) {

        av_free(c);

        exit(1);

    }

 

    /* decode until eof */

    avpkt.data = inbuf;

    avpkt.size = fread(inbuf, 1, AUDIO_INBUF_SIZE, f);

 

    while (avpkt.size > 0) {

        int got_frame = 0;

 

        if (!decoded_frame) {

            if (!(decoded_frame = avcodec_alloc_frame())) {

                fprintf(stderr, "out of memory\n");

                exit(1);

            }

        } else

            avcodec_get_frame_defaults(decoded_frame);

 

        len = avcodec_decode_audio4(c, decoded_frame, &got_frame, &avpkt);

        if (len < 0) {

            fprintf(stderr, "Error while decoding\n");

            continue;

            exit(1);

        }

 

And this doesn?t work, len reports always -11 (not sure what this means) 


 

Any help is more than welcome !


Thanks,

Sven

I still think it goes without saying that you will have to 
test the result of above command to find out if it still 
works or not (if the input file is mov there is a high 
chance that the command breaks the file). If it does not

Then please provide the sample!

It really doesn't matter if you report the problem 
here or on trac (trac is slightly preferred), neither 
does it matter where you upload the sample, I even 
accept megashit (although most developers do not).

I know that it makes things more difficult that our 
upload server is currently not working, there is 
nothing we can do about it atm.

Thank you for reporting problems, this is one of the 
most important things users can do!

Please provide the sample and consider explaining 
how it was produced / which software plays it.

I uploaded the file to :
https://skydrive.live.com/redir?resid=304528F9BA71B11C!129
It plays fine with VLC and latest ffplay (that?s why I thought the file
should work only in sample mode).

The file was created from a TS stream, the AAC samples demuxing was done by
our own application.

Hope this helps !
Thanks,
Sven

it will break the file as the moov atom is the last atom in this case
(I checked)

ah, of course, didn't think of that option. thanks!

OK, then I guess it makes most sense to upload the whole file so you
have an original unmodified file from that camera and you can decide
for yourself whether you want to cut it. I'll upload it later today
and submit the bug report.

Subject: [FFmpeg-user] Performance issue/question (maybe my misunderstanding)
Message-ID: <1345473512.1917.39.camel@mordor.haefemeier.eu>

Hi,
I am a little confused about, what kind of resources are needed to
transcode a video for example 'mpeg2video -> libx264', as in my case. It
can't be ruled out my understanding is wrong, but it confused me. But
let me explain from the beginning.

I have two computer. An older one with an 'Intel(R) Core(TM)2 Duo CPU
E8400 @ 3.00GHz' and a brand new 'Intel(R) Core(TM) i7-3930K CPU @
3.20GHz'. The first has two cores (2 threads, 6M cache), the second 6
cores (12 threads, 12M cache).

My thoughts are the second should be faster to transcode videos as the
first one. But it isn't! My new computer was <10% faster as the other.
It seems to me there are some parameter which are influent the process.
But I have no idea which?

To my background: I am not new to computer at all or there architecture
(> 20 year experience in linux environment and software development),
but started to undersand how video transcoding works.

You will find attached a textfile with a complete console output of a
transcoding the same video on both machines. If you need more, please
contact me.

Any hints, possible explanations or discussions are welcome.

Bye
	Frank

P.S.: Please don't misunderstand me. It isn't the absolute time, it is
the small differences between them.

Try to monitor actual CPU load during transcoding on both PCs. I
suspect libx264 may be not using all 6 cores for all 100% because some
threads have to wait for others to interoperate. Changing x264
threading options may (or may not...) change this result.

I see that you've built ffmpeg manually, and in seemingly same way.
I'd check also libx264 build options - is it built with fine
optimization settings?

Message-ID: <EA77CFD1-1099-46A1-8846-B8FD462C8A2C@verizon.net>

I have an FLV that is relatively good quality and I'm trying to convert it so that I can transfer it to my TiVo.  I've tried Mpeg-2, avi, and mov and regardless of the options I choose I can't seem to get the same quality out of the converted file.  Here are the results of my last try.  I also don't understand the Error while decoding stream message at the end.  The output seems to have all of the file in it.

This was probably the closest. I did a number of searches with Google and in the archives but I can't seem to get it right.  Any help is appreciated.

I'm on Mac OS X 10.8 and installed ffmpeg from macports yesterday.

Thanks,

Hi,
I followed the following link to build my ffmpeg 

https://github.com/halfninja/android-ffmpeg-x264
and found the code in the git is not compiling.

Please fix it.

> threading options may (or may not...) change this result.
This is the place where I am not deep enough to understand most of x264
parameter. I changed with -threads the thread count, but the result was
sometimes strange. I made tests and in some cases the older machine was
faster as the new one...
Do you have some examples of what kind of threading options I can try.

What kind of options do you mean?
I built libx264 manually as well. I use the x264-snapshot-20120612-2245.
x264 configure script
Command line options: "--prefix=/home/frank/software" "--disable-cli"
"--enable-shared" "--enable-static"

platform:      X86_64
system:        LINUX
cli:           no

Try this command:

I'm not an expert, too. I'd ask x264 developers for advice on options
for 6-cored box. They have irc channel and maillist.

Sounds like this is like a new "libavcodec" member or something.

I might ask the libav-user group.

No, it is a video format. I believe h.265.

whoa! That's some big file.  I assume your computers are both
desktops? What if you try it with -threads 1? Are you possibly limited
by disk speed?

Otoh, a download page where you have to login (like

The sample is not longer than 21 seconds and decodes fine 
afaict. I don't know much about library usage but do 
other audio files decode fine for you with your application?

Hi Carl,

No, I didn?t managed to decode a LATM file as shown in the source code.
I also made a few tests with other LATM files, created by different
applications - without success.
That is a little bit strange, because everything works fine if I play the
file as it is with ffplay.
Maybe there is something wrong with the initialization part of ffmpeg in my
sample code ?

Just the ADTS version of the files are ok.

I can try to remove the LATM header and create a ADTS header, but I am not
sure.
Any suggestions ?

Thanks,
Sven

The source file has a size of 2.5 GB and is an one hour video captured
from our local cable network. This is not too big I think to get a big
influence from disk speed. But in my opinion it does not explain why
aren't the difference in speed between both machine are so small.
The absolute time is not the important part here. It was transcode with
the slowest preset I could found for libx264.
If you compare the real time of both computer you will see the new
computer is 14% faster as the old one. And I think this is too small.
But I have no idea at the moment if there is a logic explanation about
it or only I have a complete wrong understanding of it.
That is the reason to start the discussion here. I will also start in
the next days a similar discussion in a x264 mailing list to collect
more information.
Because I think it is not a specific ffmpeg or libx264 issue. Or
possible it is... I am confused:-|

I will start a new test with -thread 1 and the same source file soon.
I'll keep you informed.

You could try using x264's binary [?] and/or mencoder and see if they
have similar attributes.
Also maybe try compiling it with:
--arch=native
possibly...

Looking at these numbers, I would suggest to try to run with only 2 threads
on the i7 and see if it makes a big difference.

Also, the suggestion of using x264 binary directly is sound, because if x264
for some reason wastes its time eating 9 threads for nothing, it is there
that it must be reported.

Some additional information, Carl.

Using verbose debug results in :

[aac_latm @ 002d3b80] no decoder config found
[aac_latm @ 002d3b80] no decoder config found
[aac_latm @ 002d3b80] no decoder config found

Does this help ?

Sven

No, it's a video codec and the successor to H.264/MPEG-4 AVC. See

Message-ID: <CALu283HZxF3z=_d=uqtirAcbLN=8=82Hv_E-gzHmguYKGRvEKQ@mail.gmail.com>

Hi,

so for some reason ffmpeg ignores my fat bit rate here. I tried a lot
of combinations already, but could not force ffmpeg to encode flv at
high rate. For example:

./ffmpeg -i ScreenFlow.mov -f flv -b 100000k -minrate 90000k -g 1
~/Documents/output.flv

This command output is:

...
Output #0, flv, to '/Users/makc/Documents/output.flv':

:(

Why?

Apparently my problem is not a common one (google returns nothing
useful) so I must be doing something wrong, right?

When using the lowest possible quantiser the encoder cannot produce any
more bits.  40Mbit would seem to be the largest the encoder can manage.
 If you fiddled with the encoding options you may be able to eke out a
few more bits but I doubt you could get it to 100M.

Now for the question, why do you want 100M?

if you use crf 0 does it even get to that high a bit rate?
Using "ultrafast" might make it use more bandwidth, if that's your desire.

I need to process the video in flash runtime based tool, locally, so I
prefer quality over size. However, even at these insane rates I get
shitty output (compared to source video) Google comes up with
anecdotal evidence to support codec limitation theory: "We spend days
running tests. I'm pretty sure that is a point with both those codecs
where increasing the bitrate doesn't make a difference to visual
quality" http://forums.creativecow.net/thread/190/857637

Flash runtime also understands f4v video, but when I do ffmpeg -i
my.mov -sameq -g 1 out.mp4 it does not seem to respect "g 1" setting,
and that breaks seeking :(

crf 0 should be "high quality" (lossless)
http://ffmpeg.org/trac/ffmpeg/wiki/x264EncodingGuide
if you're using libx264. Not sure about flv though...

I get 172Mbit with -vcodec huffyuv btw so I guess the video resolution
is enough to generate 100M bitrate, if that's what you're asking

There's a similar problem http://doom10.org/index.php?topic=222.0
though they think it's on decoding side. Ugh, what do I do now.

huffyuv is basically raw bits "zipped up" so it uses much more
bandwidth.  x264 probably couldn't use that much bandwidth even if it
wanted to.  Do you get "high quality" flv with crf 0? or -q 0 (or -q 1
or whatever it is)?

Subject: [FFmpeg-user] Problems enabling libfaac
Message-ID: <5157465.5.1345539864671.JavaMail.root@zimbra>

Hi all

I've tried to enable libfaac, and it compiles right, or so it seems, but faac isn't listed with 'ffmpeg -codecs', running Ubuntu 12.04. ffmpeg is compiled from source with '--enable-libfaac --enable-nonfree --enable-encoder=libfaac --enable-decoder=libfaac'. During compilation, I can see that libavcodec/libfaac.o is built, but ffmpeg -codecs doesn't list it. 

Any idea what to check? Full version output from ffmpeg -codecs shown below

thanks

roy

Note, the names of encoders and decoders do not always match, so there are
several cases where the above table shows encoder only or decoder only entries
even though both encoding and decoding are supported. For example, the h263
decoder corresponds to the h263 and h263p encoders, for file formats it is even
worse.

You have two problems. The first problem is that someone changed the meaning
of -codecs, now you have to use -encoders to find out the list of enabled
encoders.

The second is this:

You built ffmpeg with shared libraries, and you run it without installing
and without setting LD_LIBRARY_PATH: the dynamic loader uses the installed
system libavcodec, which does not have libfaac enabled.

> Do you get "high quality" flv with crf 0?

As I said, it does not make a difference. Here are original and
resulting frames compared, from
./ffmpeg -i ScreenFlow.mov -f flv -b:v 100000k -minrate 90000k -crf 0
-qmin 1 -qmax 1 -g 1 ~/Documents/output.flv

As you see (if this ML allows attachments) there is some kind of bevel
around high colored features (red and green), even at 40Mbit rate.
There seems to be nothing I could do to make this codec work better :(

BTW, it says it does encode in 'yuv420p' format - maybe that does not
allocate same bits for Y and UV?

yeah yuv420p is "lossy" so use yuv422 or the like (though I don't know
too much about it).
Also I'm not sure if
Video: flv1
is the best codec to use.

Thanks - I guess this means ffmpeg -codecs -encoders?

libfaac is installed in /usr/lib, being system default. Normally this shouldn't need adding to LD_LIBRARY_PATH

/usr/lib/libfaac.so

Is there another way I can fix this? I tried --enable-static as well without that helping much?

I already checked
https://github.com/FFmpeg/FFmpeg/blob/master/libavcodec/flvenc.c#L97
and it seems PIX_FMT_YUV420P is the only supported format, so I guess
I officially ran out of my options with this course of action.

You can try for yourself, but I believe this is just ffmpeg -encoders.

I am not speaking about libfaac, I am speaking about the system's libavcodec
versus the one you just built but not installed. Just try "ldd ffmpeg" and
see for yourself.

Hello all.

Again thanks for you help the other week "ffmpeg still to video question".

I thought I had everything squared away, but not quite.

I am using this right now:

/usr/local/bin/ffmpeg -r 5 -f image2 -i
/var/www/FTGweather/loop/FTG%2d.jpg -vcodec libx264 -level 4.1 -vprofile
high -preset veryslow -crf 18 -r 30 -y /var/www/FTGweather/FTG.mp4

********************


The movie file is being read by a Digital Signage player via mrss feed. 
Some of the boxes are playing the video fine, but some are not.

I notice in VLC that for the codec, it says "H264 - MPEG-4 AVC (part 10)
(avc1)"
I am a bit confused about the "avc1", as in reading around most say that
this is fine that they are the same and just the way VLC sees some codecs,
others say it makes a difference.

I am not sure if that is what is throwing things off or not.  The
manufacture only says the following about H.264:

H.264 (MPEG-4, Part 10)
AAC audio supported with H.264 files
Main or High Profile up to level 4.1
CBR audio (vbr not supported)
Maximum bit rate recommended is 25Mbps
Maximum video resolution supported is 1920x1080p (progressive)


I am meeting all the requirements they list, but of course there are other
video options for H.264 that are not discussed.

I'm just asking to see if it is this "avc1" that is possibly an issue, or
if anyone sees anything else in what I am doing that may be a problem.

Thanks for the information and help as always!

John

i stuck at the following error :

Error while opening encoder for output stream #0:0 - maybe incorrect
parameters such as bit_rate, rate, width or height


here is my configuration :

ffmpeg -re -y \
-loglevel warning  \
-loglevel verbose \
-i rtp://239.0.12.1:5000 \
-bufsize 3000k \
-an \
-filter:v yadif \
-vbsf h264_mp4toannexb \
-maxrate 3000k \
-r 32 \
-b:v 512 \
-s 240x320 \
-vcodec libx264 \
-vsync 2 \
-preset fast \
-preset baseline \
-f h264 -f rtp rtp://10.0.254.47:5000

I was also trying to play with all the parameters specified in error ,
taking in consideration that in x264 they should be divided by 16 , i was
switching rate parameter from 16 to 50 and so on , nothing doesn't change.
Also i was trying to configure different versions of ffmpeg, but still
getting such a type of errors.

That reason is fine.  You could also try the following but it is
equivalent to your setting qmin and qmax:
ffmpeg -i INPUT -qscale 1 -qmin 1 -g 1 OUTPUT.flv

As for the poor quality you claim you are getting.  I cannot see any
difference between a test video as input and this high bitrate output
from ffmpeg.  FYI with this video I managed to get 61M out of the encoder.

If you do that, you will not get a file that flash understands.  ffmpeg
will use the mpeg4 encoder not h264.  For that you would have to use
libx264.  Anyway, I cannot reproduce your report that ffmpeg is ignoring
-g 1 with either mpeg4 or libx264

Now on to Roger's suggestions.  -crf 0 does nothing because it is an
option only for libx264.  You may attempt lossless encoding with libx264
if you like but I don't think flash can decode it.  Huffyuv is also not
supported.  As for the claim that yuv420p is lossy, that is only true if
the input video does not already have 4:2:0 chroma subsampling.  You can
try yuv422p and libx264 if you like.  I think I have read that flash can
decode it.

Perhaps you should heed the warning libx264 printed because as it stands
the limitation of level 4.1 is not being met.  Have you also tried
resizing to a "standard" resolution of 720x480, 720x576, 1280x720 or
1920x1080?

again, I mentioned in another mail that I might be actually running
into this issue: http://doom10.org/index.php?topic=222.0

so to sum up, I had to extract the set of frames I need into png files
(that obviously have no quality degradation issues) and work on those.

Maybe you need the baseline profile for maximum compatibility?

In that case my guess is that all "flv" encoded files are lossy.

James,

Thank you for your response.

I have tried other resolutions as well as levels 4 and 4.1 as well. The
version I posted just happened to be the 1 to 1 version, keeping things
the same resolution as the image set being converted to a movie.

I see you also quoted the DPB size line.  If that is also a possible part
of the problem, how does one keep the DPB size from going over the level
limit?  I looked around a bit and see some references to turning off
bpyramid by adding the "-flags2 -bpyramid" option, but that didn't seem
work.

John

Oh yes, sorry I omitted that part.  You will have to limit the number of
reference frames with the -refs option, in this case it would be: -refs 15

I thought the system-installed libfaac should do?

Subject: [FFmpeg-user] time padding when muxing
Message-ID: <50345633.6090808@gareus.org>

Hi all,

Suppose I have a 1 minute video and a 2 minute audio track.

I want a muxed version:
  20 sec black,  the 1 min video, 40 sec black
along with the 2min audio-track.

Is this possible using a single command?


-=-

Using '-t' and -itsoffset synchronizes A/V correctly. But the first 20
seconds is audio-only and video-window (mplayer or VLC) only opens after
20sec. Also the last video-frame remains frozen for the final 40sec.

-=-

A rawvideo pipeline can do the trick, IFF I query and parse the geometry
and fps of the video first. I'm also uncertain if that'd work x-platform
(windows pipes, anyone?), and besides that it is not very elegant:

( \
  ffmpeg -s $SIZ -f rawvideo -pix_fmt rgb24 -r $FPS   \
                 -i /dev/zero -f rawvideo -t 20 -;    \
  ffmpeg -i $INPUTVIDEO -f rawvideo -pix_fmt rgb24 -; \
  ffmpeg -s $SIZ -f rawvideo -pix_fmt rgb24 -r $FPS   \
                 -i /dev/zero -f rawvideo -t 40 -     \
) \
| ffmpeg -s $SIZ -pix_fmt rgb24 -r $FPS -f rawvideo -i - \
         -i $INPUTAUDIO \
         ..ENCODER..PARAMS..

Is there a better solution?

TIA,
robin

I wonder if it's possible by inputting a single "black image" for the
first x seconds...but that doesn't feel too elegant either...

It has nothing to do with the system-installed libfaac. Please read
carefully the "configuration" lines of your console output, and try ldd on
your ffmpeg binary as I advised you to see for yourself.

With the color video source and the concat video filter, it seems quite
easy:

ffmpeg -i video.mkv -i audio.wav -vf "
color=c=black:s=${SIZ}:d=20 [pre] ;
color=c=black:s=${SIZ}:d=40 [post] ;
[pre] [in] [post] concat=n=3" output.mkv

We miss your full console output, but i suppose that RTP UDP stream is
too voluminous, so your computer cannot transcode it in real time:
while you transcode a frame, you loose packets in UDP socket buffer,
thus decoding fails frequently. ffmpeg reports about encoding only 1.6
frames per second.
Try using more powerful server, or avoid transcoding media.

See below for ldd output. What more should I need than libfaac and its -dev counterpart? Will I need the source code for it to build this correctly?

Also, sholdn't configure or the build process somewhat fail if a module couldn't be built?

Sorry if this seems all too obvious to some, but I'm at loss?

Please try to rebuild your ffmpeg and enable static build and disable
shared. Please don't forget to call 'make distclean', to prevent side
effects. 
If you have done it, you can call ffmpeg without installation directly
from the build directory. Then there are no influences of ffmpeg
internal libraries (like libavcodec, libavutil, ...) coming from your
system.

Again, it has nothing to do with libfaac.

> root at media2:~/src/git/ffmpeg# ldd /usr/bin/ffmpeg 

This is not the ffmpeg binary you just built, it is the system ffmpeg, and
as such does not have the configuration you want. Therefore, this ldd output
is completely useless.

But let us assume it was not:

> 	libavcodec.so.53 => /usr/lib/x86_64-linux-gnu/libavcodec.so.53 (0x00007fe86e4c2000)

It loads the system's libavcodec, which does not have the configuration you
want either.

Now, try again, but this time with the ffmpeg binary you just built, and
notice the difference, or rather the lack of difference.

Subject: [FFmpeg-user] live real time stream transcoding
Message-ID: <1345636030933-4652823.post@n4.nabble.com>

Hello everyone,

I have a project which is based on some real time transcoding. The stream is
coming through the rtp protocol,
source stream look like rtp://239.0.12.1:5000.

Stream parameters:
-----------------video---------------
type: Video
Original ID:403
Codec: H264 -MPEG-4 AVC (part 10) (h264)
Resolution: 720x576
Frame rate:50

------------------audio----------------
Tyoe:Audio
Original ID : 404
Codec: MPEG Audio layer 1/2/3 (mpga)
Language: English
Channels: Stereo
Bitrate:128 kb/s

the following stream i want to transmit to some streaming server, and from
this streaming server to have such a possibility to watch in real time using
mobile smart phones and local PC.

The server that I'm using is having the following parameters:
http://pastebin.com/DLVL85hX

Server OS:

Linux stream 2.6.32-5-amd64 #1 SMP Mon Mar 7 21:35:22 UTC 2011 x86_64
GNU/Linux

lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux 6.0.1 (squeeze)
Release:        6.0.1
Codename:       squeeze

At the moment I'm using the following version of ffmpeg:
http://pastebin.com/b5gS0c5g

ffmpeg command line look as follows:
http://pastebin.com/ubZHGXCg

There is what I get during transcoding process:

Thank you in advance.

Thanks for your reply again.
Yes, I'm trying to replace x264 with CUDA encoder :)

Is there any way to see a video file properties in detail using ffmpeg?
could you please write the command.
I use 
            ffmpeg -i inputfile,
but it only shows a few information. I need to know something like
-deblocking (used/ not used), IDR period, frame or field mode, etc.

thanks

Message-ID: <0F9A5278-2E09-451D-BC14-5FE7BB1AE860@bitgravity.com>

What exactly is the 'q=' referencing in the logging output? I know this is quality, but I'm not finding any useful info on the web to put any kind of key or legend to this value.

Thanks in advance!

Michael

It's the one I built as a deb package and installed. The original package from upstream is not in use.

The dpkg-buildpackage process built all the libavcodec packages as well, and these are installed, just as ffmpeg.

Thanks to Frank btw, for the suggestion on building ffmpeg static only. This seems to solve the linking with libfaac.

Vennlige hilsener / Best regards

You did not write anything about building a package until now.

If you still have several different "configuration:" lines in the banner
printed by ffmpeg, then you did something wrong installing the libraries.

Unfortunately, it only hides the issue under the carpet.

Subject: [FFmpeg-user] Mpeg2 Encoding problem
Message-ID: <254141475.20120822203143@pixbyte.com>

Hello ,

I  try  to convert a x264 video to mpeg2. I set the bitrate to 6000000
but  the  resulting  video  is  never bigger than 1.6 GB. The video is
around 90 mins, I expect a much bigger mpeg2 than 1.6 GB.

Is  there  a known problem with mpeg2 or a special settings to "force"
the bitrate?

Regards,

Ingo Foerster

My guess is it can't keep up fast enough with the input so it drops
some (useful) packets.

What if you just save the input to a file, do you get those same error messages?
[h264 @ 0x2634720] non-existing SPS 1 referenced in buffering period

[h264 @ 0x2634720] non-existing PPS referenced

[h264 @ 0x2634720] non-existing SPS 1 referenced in buffering period

[h264 @ 0x2634720] non-existing PPS 0 referenced

[h264 @ 0x2634720] decode_slice_header error

[h264 @ 0x2634720] no frame!

or save it as -vcodec copy?

I think it's this:

?-q[:stream_specifier] q (output,per-stream)?
 ?-qscale[:stream_specifier] q (output,per-stream)?

Use fixed quality scale (VBR). The meaning of q is codec-dependent.

> I've tried to enable libfaac, and it compiles right, or so it seems, but faac isn't listed with 'ffmpeg -codecs', running Ubuntu 12.04. ffmpeg is compiled from source with '--enable-libfaac --enable-nonfree --enable-encoder=libfaac --enable-decoder=libfaac'. During compilation, I can see that libavcodec/libfaac.o is built, but ffmpeg -codecs doesn't list it.

What if you try and use it, like:
ffmpeg -i input.wav -acodec libfaac yo.aac
or the like?

there's a -max-rate and -min-rate but if an encoder can't reach that
rate even at their highest quality levels, then it could still fall
below it.
