(Command line and complete, uncut console output missing.)

Patch welcome, you may misunderstand how open-source 
development (or at least how FFmpeg development) works.

This is too old, please update to current git head and 
run ./configure --help to find out about the various 
relevant options.

Subject: [FFmpeg-user] ffserver and muxing
Message-ID: <CAP0asiVsu4RYy9po7jOLQZneXFfyHEkZRx23FLz5Nm0E=C+xxg@mail.gmail.com>

Hello folks,

I chalange a problem about muxing. When I use muxing code to send frame to
ffserver realtime stamp is not writing to ffm file right. However, if I use
ffmpeg for the same process, realtime stamp is available to seek ffm file
then. I didnot find what the difference is. I suppose, pts property is the
keyword of this problem. Could you please to assist me what the solution is?

Is there any way to make

ffmpeg -i <web address of media file> (various options) outfile.ext

restart from last attempt automatically., after a previous attempt 
failed for some reason leaving a partially downloaded file??

At least for some types of sources and/or output file types/formats???

Like rtmpdump could/can.

Message-ID: <CANiVzYzJfDRzM2iahpR8Ni69fdVSZdLu+r6aPjwNyHT=MpySsA@mail.gmail.com>

I'm trying to output a 10bit DNxHD.mxf, but FFMPEG is saying I have
incorrect parameters:

*Error while opening encoder for output stream #0:0 - maybe incorrect
parameters such as bit_rate, rate, width or height*


The source files are always 10bit ProResHQ.mov.

Please see the full command statement and output below.

Can someone please help me troubleshoot this problem?

I don't think 30000/1001 equals 29.97

No it equals 29.97002997.... but I thought that was regarded as good enough.

Subject: [FFmpeg-user] how to transcode yuv video to h264 by ffmpeg
Message-ID: <CAFd2cZUSHcTuWt2uMYGPNcpnrtNoU-1SVf7SqBULB72QAXZB+w@mail.gmail.com>

Hi All,


If I would like to transcode YUV video data to H.264, then use ffserver
output the h.264 video as stream
the command below :
ffmpeg -sn -f video4linux2 -r 5 -s 1280x720 -input_format yuyv422 -i
/dev/video0 -vcodec libx264 http://localhost:8090/feed.ffm


is there anything wrong in the command?

If I would like to output CBR H.264 stream, how to modify the ffmpeg
command line?


Any input is very appreciated!


Thanks!

True, the original command line is missing -flags ildct
(To respect the "i" in "1080i")

If someone has a link to a simple tutorial about this, pass it along.

Simple application.

Using latest Ubuntu-13.10 + ffmpeg-2.1.1 - the best way to stream
audio + video directly to an HDMI port connected to a TV.

Thanks.

Apart from "don't highjack mailing threads, this is 
(also) very rude":
Streaming audio via HDMI is completely straight-forward, 
I am not sure what you mean with streaming video:
There is -f sdl and -f xv (and both work fine with HDMI) 
but ffmpeg is not a media player so I think I don't 
understand your use-case.

Or would "Use MPlayer" be a possible answer?

I'm looking for the simple command, something like...

ffmpeg -i foo.mp4 /dev/hdmi

Maybe this is so simple, I'm just missing it.

So I guess two questions...

1) How do determine the HDMI device on a given machine

2) Syntax to stream a .mp4 file to the device

Thanks.

If your graphic card has a hdmi port, this is considered as a screen, you
just need to go to the display menu in the preference menu and activate it.
Than any player will do the job on this display.

$ aplay -l

$ ffmpeg -i input.mp4 -f alsa hw:1,7

The actual device depends on your hardware.
I am sure there are non-alsa alternatives for all 
commands but I always only tested alsa.

Sorry if this is hard to follow. I've including the output of 3 different

wondering if there's actually an issue with #1 and/or my install.

I have a web-based system where videos can be uploaded and played using
JPlayer. I am converting all the videos to H264 using the following:

For the most part this seems to work and the videos play fine in JPlayer.
However, I have discovered that if I take the converted video file, and try
and convert another still image, I just get a gray image.

I suspect you just have to update FFmpeg to 
current git head.
If the problem is reproducible with current 
git head, please upload sample(s).

Message-ID: <CAP0asiXQgyuMh4pML=SbGfTHKMggk+1Xr_iJxWCx__YHVnLUbg@mail.gmail.com>

Hello,

I seeked any corner of the web and have found nothing about this issue. Yes
I understood the main idea of the time positioning of pts and dts. Tough I
implement any detail of this, realtime seek cannot be realized via
ffserver. I found the property start_time_realtime  in the format context
but yet I didnot find any suggestion to use it. How can I insert AVPacket
to realtime stamp. Please give me a hand. I really tired to search.

Ok, Inserted DVD, ran: 


$ /usr/bin/mplayer -dvd-device /dev/sr0 dvd://1 -dumpfile dump-1.vob -dumpstream

$ dd if=dump-1.vob of=dd-vob-short.mkv count=400K
$ ffmpeg -t 280 -i dd-vob-short.mkv? -map 0 -c copy -c:v libx264 -vf 
"fps=30000/1001,fieldmatch,yadif=deint=interlaced" -crf 17 -preset 
veryfast dd-vob-short-fieldmatch-yadif.mkv

$ ffmpeg -t 280 -i dd-vob-short.mkv? -map 0 -c copy -c:v libx264 -vf 
"fps=30000/1001,fieldmatch" -crf 17 -preset 
veryfast dd-vob-short-fieldmatch.mkv


Both ffmpeg commands had output containing:

Frame #8158 at 272.205 is still interlaced time=00:04:31.64 bitrate=2622.3kbits/s
[Parsed_fieldmatch_1 @ 0x7d10c54850] Frame #8159 at 272.239 is still interlaced
[Parsed_fieldmatch_1 @ 0x7d10c54850] Frame #8160 at 272.272 is still interlaced


So I focused on those frames.?
$ ffmpeg -t 2 -ss 271.205? -i dd-vob-short-fieldmatch-yadif.mkv? dd-vob-short-f-y-%2d.jpg

$ ffmpeg -t 2 -ss 271.205? -i dd-vob-short-fieldmatch.mkv? dd-vob-short-f-%2d.jpg


By comparing with the original frames, the desired frames are 32, 33, 34. They appear identical, including using gimp's difference filter.

I'm uploading dd-vob-short.mkv, dd-vob-short-fieldmatch-yadif.mkv, dd-vob-short-fieldmatch.mkv, and dd-vob-short-f-{,y-}3{2,3,4}.bmp as robbins-from-dvd.tgz to upload.ffmpeg.org/incoming

dd-vob-short.mkv is the output from 

$ dd if=dump-1.vob of=dd-vob-short.mkv count=400K

It is in the tarball which seems to still be uploading.

Message-ID: <CAMAD-2zQACx_MD4YPncyrP-0Bo2RXe8jnxY1gpcP+g6FCYw7sw@mail.gmail.com>

When I capture video directly from x11grab at 30 fps it seems to work
correctly and the encoder reports getting about 30 fps. Here is what the
output looks like: http://pastie.org/8524085. However when I try to capture
simultaneously using video4linux2 and overlay the two streams, the encoder
reports getting only about 5 fps. Here is some sample output:
http://pastie.org/8524055.
If I understand correctly, the overlay filter should use the timestamps
from the first input stream, so the fps should remain unchanged in the
overlayed video. I have noticed that using -r 30 on the x11grab input
creates a 30fps output stream, so perhaps this is a problem with the
timestamps being returned by x11grab. Any ideas?

The links above show text that appears to be cut off with no scroll bar and
the output largely appeared on one line, but I eventually figured it out.

In each of these, the fps output I see I believe is the rate
at which frames are being encoded.   In other words - how fast 
ffmpeg is able do the the encoding as opposed to the ultimate playback rate.

Hope that helps.

The video is being encoded in real time so the fps at which it is encoding
matching the fps at which it receives video. The resulting video does not
playback correctly as well in the overlay example but does in the first
example.

I forgot to mention that the output also shows many dropped frames.

The issue of dropped frames is more visible if I pass the x11grab stream
through showinfo. Here is what this looks like with no overlay using the
command
~/git/ffmpeg/ffmpeg \
        -f x11grab -video_size 1680x1050 -framerate 30 -i :0.0 \
        -vf showinfo -y \
        test.mkv

http://pastebin.ca/2488878

Notice that the pts values correspond to approximately 30 fps.

Now suppose I run the overlay and insert showinfo before the stream is sent
to overlay using the command
VF="
[0] showinfo [screen];
[1] fifo [webcam];
[screen][webcam] overlay=W-w
"

~/git/ffmpeg/ffmpeg \
        -f x11grab -video_size 1680x1050 -framerate 30 -i :0.0 \
        -f video4linux2 -video_size 320x176 -framerate 30 -ts abs -i
/dev/video0 \
        -filter_complex "$VF" \
        test.mkv

http://pastebin.ca/2488911

Notice that in 11.8 seconds I have only 86 frames! So frames are being
dropped somehow before they even reach the overlay filter.

My guess would be that maybe you've exceeded your hardware's ability to render in real time? Right now I'm rendering two streams of 4k video (mp4, web) and with 4 of my Mac's 8 cores very busy, I'm rendering at a rate of 0.2 fps.  (Yes: 5 seconds per frame - it's just a  test.)

But that's at or beyond my knowledge of ffmpeg at this point.

Subject: [FFmpeg-user] building the latest stable release (2.1.1) on windows
 8 x64 with cygwin
Message-ID: <529DCCE0.9030103@gmail.com>

Hi folks, I need your help to figure out the correct steps of building 
the latest stable release of ffmpeg on windows 8 x64 and CYGWIN. I have 
written a sh script file with the following configuration :

    |./configure --enable-static --enable-gpl --enable-version3
    --enable-pthreads --enable-avisynth --enable-bzlib \
       --enable-fontconfig --enable-frei0r --enable-gnutls
    --enable-iconv --enable-libass \
       --enable-libbluray --enable-libcaca --enable-libfreetype
    --enable-libgsm --enable-libilbc \
       --enable-libmodplug --enable-libmp3lame
    --enable-libopencore-amrnb --enable-libopencore-amrwb \
       --enable-libopenjpeg --enable-libopus --enable-librtmp
    --enable-libschroedinger \
       --enable-libspeex --enable-libtheora --enable-libtwolame
    --enable-libvo-aacenc \
       --enable-libvo-amrwbenc --enable-libvorbis --enable-libvpx
    --enable-libwavpack --enable-libx264 \
       --enable-libxvid --enable-zlib --disable-shared --disable-doc
    --enable-nonfree --arch=x86_64
    |


I installed all the pre-requisites, according to the official 
documentation, and then the configuring step is smoothly performed. Just 
after that, I usually run from shell :

    |make -j5
    |


to perform parallel build of the source code. After the process is 
finished, i usually run from shell :

    |./ffmpeg.exe -version
    |



and i get a null output. By using a windows shell i get a linking 
libraries error ("cygass-4.dll is not found" and so on), where am i 
wrong ? Before posting I read a lot of guides on the forum an over the 
internet by googling around but i can't still figure out which is the 
real issue.

Please help me out. Thank you in advance

Please understand that there is nothing "stable" about 
FFmpeg releases (or, more exactly, nothing "unstable" 
about current git head), releases are simply snapshots 
for distributors.
Is the problem reproducible with "./configure && make ffmpeg"?
Does "ffmpeg -f lavfi -i testsrc out.png" produce a file 
out.png (is only the console output missing)?

At least the following options are useless in your configure 
line (from a quick look):
--enable-static
--enable-pthreads
--enable-bzlib
--enable-iconv
--enable-zlib
--disable-shared
--arch=x86_64

Most people agree that the quality of libvo-aac is worse 
than the native aac encoder.

Why do you need --enable-nonfree ?
(I may miss something.)

Some of the external libraries that you include are very 
rarely needed.

Message-ID: <CAK6GkD02u-fXBbiWwRh3fkBFr7hf22byUFLWjh1BrLjHKgmgSg@mail.gmail.com>

Hi,
I am just curious to know, if the following file sizes sound ok after
transcoding with ffmpeg. Let me know what other information maybe needed.

I have an input video of around 10:11 of video in mp4. Conversion to mpg
with ffmpeg is done as follows.

ffmpeg -i in.mp4 -vf subtitles=sub.srt -codec:v mpeg2video -codec:a mp3
in.mpg

The mpg is then converted to VOB as follows. This is so that dvdauthor can
be used to add titles, chapters, etc.

ffmpeg -i in.mpg -target ntsc-dvd in.vob

After dvdauthor is run on in.vob, I am converting the DVD structure to .iso.

So, the file sizes are as follows:

in.mp4 - ~20MB
in.mpg - ~30MB
in.vob - ~109MB
dvd.iso - ~219MB

Thus, in other words, a 10 minute video is around 200MB in ISO format. I
understand, the behaviour of dvdauthor and mkisofs is not in the scope of
this forum. But, in your experience, is this 10 fold increase normal ?

Is there a way to use ffmpeg to record audio and save it as a FLAC file on Mac OS X? I have seen Linux options but none for Mac.

I would like to avoid using SoX because I've had some compatibility issues with it.

Something is wrong here.

To minimize quality loss because of frequent recoding, 
you should combine both above commands into one.

Output file size depends on the bitrate which depends 
on the quality that you wish for your output DVD.

Ok. I transcoded mp4 directly to PAL DVD format like so:

ffmpeg -i in.mp4 -vf subtitles=sub.srt -target pal-dvd in.vob

Now, the file-sizes are:
in.mp4 - ~20MB
in.vob - ~116MB
dvd.iso - ~117MB

The iso is now around 6 times the input mp4.

The "ffmpeg -f lavfi -i testsrc out.png" result is always a null one. I 
have just tried to replicate the exact zeranoe build configuration by 
launching his static x64 build (the ffmpeg.exe) and putting it in my 
configure section, but i'm still with no results. Any ideas about it ?

Regrads, Arturo

What does that mean?

(Afair, your console problem is related to sdl 
but I would like to rule out another problem.)

I mean that i don't get the test output file as I usuall get on *nix 
platform as macos and linux. I am attaching the result to this answer.

That?s normal.  DVD?s typically use between 3 and 8 Mbps.  MPEG-4 is a much more efficient format than MPEG-2.

Message-ID: <E4355131-DF74-4ECF-A1D3-9B1D9F8ABEA5@network13.net>

Hi All,
	I?m attempting to add a still image to an MP3 audio stream coming from an Icecast server.  I am using the following command, which outputs audio only.  The image is not looping as I expect.  If I can get the image portion added and/or to loop, the next step will be to set the video encoder to h.264 baseline 3.0 at a minimal frame rate.  But first things first?

ffmpeg -re -loop 1 -i still.jpg -i http://localhost:8002/listen -acodec copy -bsf h264_mp4toannexb -c:v copy -hls_time 10 -hls_wrap 10 -hls_list_size 6 -f hls mp3.m3u8

Message-ID: <1386131278.64728.YahooMailNeo@web163604.mail.gq1.yahoo.com>

Hello,

in order to transcode an MPEG-2 Multicast Transport Stream with MPEG-1 Layer 2 Audio?
to H.264 with AAC audio Multicast TS with a given bitrate, how would the command line look like ?

example:?
avconv -i udp://@239.100.0.1:1234?multicast=1 ?vcodec libx264 -acodec aac -f mpegts -re "udp://@239.101.101.1:1234?ttl=1&pkt_size=1316"


In addition, how do I point to a certain elementary stream, if multiple audio streams are available?
(e.g: original language and english, with different PID's )

Thanks in advance for you help

Iam really glad when I can start downsizing the multicast.

Br, Dirk?

So, that is the reason for the 'blown up' size. I am new to FFmpeg and
transcoding in general. So, thanks for the explanation.

>>>MPEG-4 is a much more efficient format than MPEG-2.
I am converting MP4 to VOB because I was unable to get dvdauthor to work
with mp* formats.

Message-ID: <A1C99B079D9BBB4FAE3C51E5EAA057035CE2D362@SINTEFEXMBX04.sintef.no>

Hi!

Earlier versions of ffmpeg could manage static Q-scale values to produce pure open loop VBR content, even with the mv4 motion vector estimation enabled. Current version seems to have this option broken, or must be initialized differently? My YUV content is encoded the following way:

ffmpeg -s cif -r 29.97 -i video.yuv -vcodec mpeg4 -flags mv4 -flags2 sgop -g 12 -qscale 4 -s 352x288 -r 29.97 -y video_Q4.m4v

If I do not use mv4 motion estimation, then, static Q scale is used! But, I want to use mv4! How can I obtain this, or is this a known issue?

Best regards

Arne

This is a wild guess, but does it change something if you write "-flags
+mv4" with a plus sign?

Taking the OBVIOUS interpretation as gospel, I'd say Charlie means using 
audio input to a computer (the microphone input, or some other audio 
device) and somehow managing to send that as a stream to ffmpeg and have 
ffmpeg save the data stream as a flac file.

Two parts; first send a stream of data from audio input to ffmpeg, and 
second have ffmpeg save it as flac.

I suppose at least the second one could be answered w/o needing to know 
more. Or else one could possibly dream up a clarification question to 
assist the writer in getting his thought process in better order, if the 
original question is partly confusing or unclear.
All with a goal of bringing us all forward, towards better knowledge and 
clearer understanding.

Which, I suppose, is the actual reason for the existence of a mailing 
list such as ffmpeg-user.....

ffmpeg -codecs | grep -i flac
returns
  DEA..S flac                 FLAC (Free Lossless Audio Codec)

so there is a flac encoder, and thus ffmpeg should be able to produce a 
flac "recording" if the signal can be gotten to ffmpeg in the first place.

ffmpeg -i ....... -acodec flac out.flac

???

Getting the audio to fdfmpeg, i e what to give as argument to  "-i", I 
suppose, is better answered by Mr. Hoyos.

Thanks, that actually helped: what does the + sign do in general to parameters?

Please either find the change introducing this regression 
or (if you want me to find it which I will do) please 
explain how I can reproduce the regression, ie how do I 
know that the output is broken?

Or does the command simply fail? (Complete, uncut console 
output missing.)

"-flags mv4" sets the flags to exactly mv4; "-flags +mv4" adds the mv4 flag
to the flags already present.

Constant quantizer encoding is enabled by the qscale flag, which is
automatically set by the -qscale option. Without the + in the "-flags"
option, you are clearing that flag afterwards.

This explains everything: I was not aware of this kind of + sign usage. Perhaps this should have been documented in the help output?

Of course, but OSX is a sort-of unix, so some sort of indication could 
probably be provided if someone feels absolutely certain that there 
actually are audio-in devices that can be specified as input for ffmpeg.

I have a nasty feeling there might be more to it than just specifying a 
device name, one should probably add something to tell if it's alsa or 
jack (under linuxy environs) or what. Or whatever the audio in channel 
protocols are in Mac OSX.

Please always include the complete ffmpeg console output for each
command. I have several suggestions, but I do not like to make
guesses. The console output is very useful.

"Boilerplate" notices do not make sense ? especially on a public

Why not just try what you are wanting?

ffmpeg -re -loop 1 -i still.jpg -i http://localhost:8002/listen \
-vcodec libx264 -profile:v baseline -level 3.0 -pix_fmt yuv420p \
-acodec copy -hls_time 10 -hls_wrap 10 -hls_list_size 6 -f hls \
mp3.m3u8

I may be missing something, but that example may be a good starting
point.

You're trying to stream copy both inputs. I assume MJPEG video is not an
acceptable format for HLS.

Hi,

Could someone please tell me how to make and install tools under the /tools
folder, ffhash for example?  I couldn't find them in "configure".  It looks
to me they are defined in certain makefiles but I couldn't make them work.

Thanks in advance.

Try "make alltools" after "configure", you will see something in
"Makefile" after "./configure".

Or more exactly: The mpegts muxer which the hls muxer calls 
does not support mjpeg.
>From FFmpeg perspective, you are responsible for what you try 
to mux into a container, so while for some combination an 
error (or warning) will be printed, others will be accepted

Note that -bsf h264_mp4toannexb makes no sense in above 
command line.

BTW, is there somewhere a list of what formats for video, audio, images

Subject: [FFmpeg-user] Best sound codec for editing
Message-ID: <courier.0000000052A0C349.00001343@p600.netmaster.dk>

If I disable sound everything is better!

I use ffplay to navigate a video to find a video section to cut out. When I  
use ffplay hotkeys ie. Pageup to go forward 10 minutes the playback turns  
into slow motion for a 10 - 20 seconds before the correct playback speed is  
reestablished.

If I add the no audio, -an, option when calling ffplay I do not have slow  
motion.

When I cut out a video section with the -ss option the resulting video has  
the same problem where the first 10 ? 20 seconds are slow motion. Like  
wise, if I disable audio I do not have the slow motion.

How do I avoid the slow motion and still have sound?

Below is the command to cut out a video section

ffmpeg -y -ss 1153 -i p20131119190433.ts -c:v copy -c:a copy

Message-ID: <52A06042.3060208@neterra.net>

Hi ffmpeg team,

I am new in ffmpeg and I have a problem that I can't solve. I use ffmpeg 
for live encoding of SD mpeg2 channels to SD h264. To do that I use the 
following ffmpeg version and command line:

The encoded output looks fine. There is a problem with micro bursts in 
output traffic. As an attachment I sent two pictures of captured traffic 
from ffmpeg and elecard encoder. On the pictures there is analyzed 
traffic by wireshark. On elecard picture you can see that traffic is 
leveled and on equal intervals. On ffmpef picture traffic is on bursts. 
On command line above I tried to deal with parameter "bufsize" but the 
result was nearly the same.

Could you help me to make ffmpeg output traffic to run without burst?

Thanks Lou!  Your example works great as a baseline.  Now I need to A) reduce bitrate on the video stream to as low as possible.  I?m not sure what the lowest frame rate can be with h.264 in a TS container, but in playing with the -r option, I am only able to get output as low as 8 fps.  Anything lower and I get zero byte TS chunks.  And B) the still image is actually being written over on disk every few minutes.  Is there a way to force ffmpeg to check the file mod time or read from disk at a given interval?  As it is, it seams to be reading the file once and caching.

Thanks!

Mike

ffmpeg lacks UDP output speed smoothing functionality. You can see in
libavformat/udp.c in circular_buffer_task() that data is output as
soon as it appears. To eliminate bursty output it is needed either to
patch ffmpeg or to substitute ffmpeg output facility with another
application's one, e.g. you could do
ffmpeg (...options...) -f mpegts - | pv -L $BITRATE | socat (...options...)

You can get some info with:

ffmpeg -h decoder=foo
ffmpeg -h encoder=foo
ffmpeg -h muxer=foo

Such as:

$ ffmpeg -h muxer=ogg
[...]
Muxer ogg [Ogg]:
Common extensions: ogg,ogv.
Mime type: application/ogg.
Default video codec: theora.
Default audio codec: flac.

$ ffmpeg -h encoder=flac

    Threading capabilities: no
    Supported sample formats: s16 s32

$ ffmpeg -h decoder=flac
[...]
Decoder flac [FLAC (Free Lossless Audio Codec)]:
    Threading capabilities: frame
    Supported sample formats: s16 s16p s32 s32p

Frank,

Thanks for this info. I am familiar with most of the options you provided.
All image sequences are at same resolution and format. So I dont have to worry about rescaling.

I am highly interested in identifying common sets of presets to create videos that will play on most devices.
Is there any guidance on common resolutions and bitrates for encoding videos playable on most devices?

As I understand the resolution and bitrates primarily govern requirements for various hardware profiles for *264 encoder.  
Are there any processes with which one can achieve higher quality output complying with restrictions imposed by hardware profiles ? 
lowering frame rate and two pass encoding come to my mind.

Thank you
-Amit

That doesn't look like the output from ffmpeg.  Those "GOING INSIDE"
message are not from ffmpeg and libx264 should print at least 1 more
line stating the profile and level it is using.

Where did you get that ffmpeg from?

Have the flags changed between the builds? I've looked but can't find a change log which would indicate what got deprecated/removed and what it should be replaced with if it has

Doesn't work either. Using this command:

# /usr/local/bin/ffmpeg -i "Input.mpg" -map 0:v -map 0:a -vf "scale=720:576:1,pad=720:608:0:32:black" -c:v mpeg2video -r 25 -aspect 4:3 -pix_fmt yuv422p -minrate 50000k -maxrate 50000k -b:v 50000k -intra -flags +ildct+ilme+low_delay -intra_vlc 0 -non_linear_quant 0 -ps 1 -qmin 1 -qmax 3 -top 1 -dc 10 -bufsize 2000000 -rc_init_occupancy 2000000 -rc_buf_aggressivity 0.25 -c:a pcm_s16le -ar 48000 -tag:v mx5p -vbsf imxdump -y "Output_IMX.mov"

Produces this output:

# /usr/local/bin/ffmpeg -i "Input.mpg" -map 0:v -map 0:a -vf "scale=720:576:1,pad=720:608:0:32:black" -c:v mpeg2video -r 25 -aspect 4:3 -pix_fmt yuv422p -minrate 50000k -maxrate 50000k -b:v 50000k -intra -flags +ildct+ilme+low_delay -intra_vlc 0 -non_linear_quant 0 -ps 1 -qmin 1 -qmax 3 -top 1 -dc 10 -bufsize 2000000 -rc_init_occupancy 2000000 -rc_buf_aggressivity 0.25 -c:a pcm_s16le -ar 48000 -tag:v mx5p -vbsf imxdump -y "Output_IMX.mov"

The MPEG2 encode step does not look like it produces the same format file as previous versions have to start with so I can't even be sure if the mux stage is working or not. Has something fundamentally changed in the mpeg2video codec?

Thanks

Have a question about ts files that are generated when I convert a live 
stream to hls. As the stream plays and is converted by ffmpeg into ts 
files then brought together in to m3u8 the number of ts files grows. If 
the live stream plays for several hours would it be wise to have a 
script of some type check for the oldest (say 3) ts files every so often 
and delete them or will this screw up the m3u8 file?

Thanks for any advice

If this worked fine and you are using now:
> -intra_vlc 0 -non_linear_quant 0 

then our option-handling decision was really very bad;-(
I suspect that  -flags2 +ivlc  became -intra_vlc 1
                       _^_                      _^_

Is that really so counter-intuitive?

Please test if that helps, if not please try to explain 
if the problem can be reproduced without mediainfo - we 
have to find the change introducing the problem.

Subject: [FFmpeg-user] Filter complex problem
Message-ID: <1386284177.56856.YahooMailNeo@web87804.mail.ir2.yahoo.com>

I have this filter

-filter_complex '[0:#$dvbsPid] scale=1280:720 [sub],[0:v][sub] overlay'

which is taking in a known 1280:720 video, resizing the dvb subtitles to 1280:720 and overlaying the 2.

PROBLEM
I dont want to have this 1280:720 fixed, what i would like is to be able to use some form of [0:v]:iw:[0:v];ih, but this does not work

So is there a way of getting the [0:v] inputs width and height to i can change the filter to be a generic filter

Todd,
	On a live stream, there are a couple of hls options that will do this clean up for you.  I use the following options when doing live hls:
 -hls_time 10 -hls_wrap 20 -hls_list_size 10
hls_time is the chunk size in seconds.
hls_wrap is the total number of ts chunks allowed on disk.  The chunks will be written over in a loop.
hls_list_size is the number of ts chunks listed in the payload file, which is sometimes referred to as the hls ?window?.  As this recycles, the #EXT-X-MEDIA-SEQUENCE tag increments to reflect the window ?sliding? in time.

Subject: [FFmpeg-user] Speed up Transcode
Message-ID: <52A10864.1060608@AleksandrSolzhenitsyn.net>

I'm transcoding avchd videos to mpeg dvd format using the following code;

ffmpeg -i Input_filename.MTS  -deinterlace -target ntsc-dvd
Output_Filename.mpeg

The transcode works very well but I'd like to speed the process up.

I've tried the following;

ffmpeg -i Input_filename.MTS  -deinterlace -target ntsc-dvd -preset
ultrafast Output_Filename.mpeg

...but there's no change in transcoding speed.

Is there a way to speed it up without buying a new computer?

Thanks,

AS

(But it is not unlikely that hardware is the 
limiting factor.)

Message-ID: <C5DE8F35-1511-4EBF-B7FD-94F9DE3B5757@network13.net>

When using segment to segment out ts files and create an hls playlist, it uses floating point values for the segment lengths in the m3u8 file.  When creating hls playlists using hls, it does not use floating point values.  Is there a way to force it to do so?

	luma
Message-ID: <CEC6A8CD.2509%matthias.husinsky@fhstp.ac.at>

Hello,

The histogram video filter behaves odd in waveform mode when using an
input file that has full range luma (yuvj420p).
Please check with this file (recorded by a Canon 5DmII):
http://www.datafilehost.com/d/acd54299

When applying the histogram filter as follows the histogram is fine (luma
values streched from 0-255)

When using the waveform mode the values are compressed into broadcast

(clearly visible with the regular spikes shown as "lines" at regular

Trying to force a certain format like this does not improve the situation:
ffplay -color_range 2 -vf
format=pix_fmts=yuvj420p,histogram=mode=waveform:waveform_mode=column:wavef
orm_mirror=1 fullrange_y.mp4



I found that applying the filter in ffmpeg and piping the output to ffplay
actually works as intended.

Now is there any possibility to achieve this behaviour in ffplay directly
(i.e. by not piping outputs)? I find it confusing that the levels and
waveform mode behave differently in ffplay.
Am I doing something wrong or is this a bug of ffplay? I?m using the
histogram mainly for inspection purposes and would prefer doing it
directly in ffplay.

Thank you,
Matthias

You get a short description and some defaults, nothing about what won't 
work, or what combinations can and cannot be handled for a specific 
container format.

Again, has anyone somewhere compiled a catalog of what won't work?

Because ffplay somehow somewhere (in middle of filtergraph) inserts
another format
filter and output to something unexpected.

ffplay is a toy. You should use something that can use better graphic
output than SDL.

Afaict, hardware is the limiting factor (I get 
ten times realtime here).
Consider using -vf yadif instead of -deinterlace 
which I suspect is a deprecated option.

Are you sure the stream is interlaced and not telecined?
It is a bad idea to use a deinterlacer on a telecined 
input stream.

Sorry, I tested 25fps SD content, so please

Message-ID: <1386338298732-4662605.post@n4.nabble.com>

Hi All

I am relatively new to ffmpeg so i trying to get my head around certain
things so apologies if this is in the wrong place, but i have been asked to
setup a service and they require the format of all audio to be in AAC, Low
Complexity Profile (LC).
I have been reading through the docs and i can see this command.
ffmpeg -i input.wav -c:a libfdk_aac -b:a 128k output.m4a

but i dont have libfdk_aac installed with my ffmpeg system i am a bit
nervous about messing with my setup as it took me a while to get it all
installed.
Here is my ffmpeg setup
ffmpeg version N-54790-g1816f55-syslint Copyright (c) 2000-2013 the FFmpeg
developers

libswresample 0. 17.102 / 0. 17.102
libpostproc 52. 3.100 / 52. 3.100

So i am trying to do the task with a different encoder libfaac which is
installed like this.

ffmpeg -i BillyGraham_1998.mp3 -c:a libfaac -q:a 330 -cutoff 15000
output.m4a

But i get the following errors
[buffer @ 0x1e12860] Unable to parse option value "0x0" as image size
[buffer @ 0x1e12860] Unable to parse option value "-1" as pixel format
[buffer @ 0x1e12860] Unable to parse option value "0x0" as image size

Error opening filters!

Any help would be really appreciated thanks

Just compile FFmpeg with --enable-libfdk-aac, do not install 
it but test it from the build directory.
If you like it, copy it with a name of your choice into a 
directory of your choice.
--enable-pthreads is useless because it is auto-detected. 
And please remove --enable-decoder=liba52 - the option 
does not exist at least for many years.

Hi,

I try to generate 5 minutes long TS file's from an udp streams. I can do it with segment (the accuracy is not very high but it works and I don't have really work on all the segment options).
My problem is : I want that the file rotate at specific time (at 00:00:00, 00:05:00, 00:05:10, ...).

Is there a way with ffmpeg to specify not a duration but, for exemple an test like timestamp % 300 = 0 ?

Another question : Can I use an extended pattern for the file name (%H for hours, %M for minute, ...) ?

For now, I work with ffmpeg 1.0.8.

Regards,
Fabrice.

You could capture the stream with simpler tool, like netcat or socat,
killing and restarting it when needed. The loss of data during restart
should be merely noticeable.

> Is there a way with ffmpeg to specify not a duration but, for exemple an test like timestamp % 300 = 0 ?

At command line level - no. You can do anything you want in
application using libavformat API.

You can do that by bash, not ffmpeg functionality.

I tried the -vf yadif but there was no change in speed.

Well, I don't know or would not know how to find out. The video files
I'm working with are from a Sony HDR cx220 video camera. It produces the
above mentioned avchd .MTS files.

The good part is the transcoding to mpeg works perfectly (so it seems)
so I can't complain.

Thanks,

Alek

Subject: [FFmpeg-user] Need help to find "proper" way to get deinterlaced
 1080p30 from lossless and 1080p60 sources.
Message-ID: <CACwWJ8nYiD-yZSVcoGebb+mxY-M+ye43RaUMU9-LjapWgrAi+Q@mail.gmail.com>

Hello everyone!

I spent quite a bit of time trying to wrap my head around
interlacing/deinterlacing, but can't seem to get any clarity on an issue.

Practical problems I am trying to solve are:
- encoding lossless lagarith 1080p30 source to x264 1080p30 which
guaranteed to have progressed frames (as youtube requires);
- re-encoding 1080p60 x264 encoded Nvidia Shadowplay source in the same way.

Main issue I have is that I can't tell if original sources are interlaced
or not and if they are not, than may be I am just wasting time and
resources using -deinterlace option?

Command line I am using to encode looks like this:
ffmpeg.exe -i %1 -map 0:0 -c:v libx264 -crf 18 -preset slow -pix_fmt
yuv420p -deinterlace -r 30 -map 0:1 -c:a copy %targetVid%

Any help will be appreciated.

WBR,
    Timur Zaripov

The trick is to force the format at the end of the filter chain, this way 
to yuvj420 -> yuv420 conversion will only take place in the very end, 
after the histogram has been calculated.

Actually ffplay sets up the filter graph only with yuvj420 input and 
yuv420 output, and avfilter auto inserts the format conversion scaler 
somewhere in the graph. (In your case, into the beginning of the 
chain rather than into the end).

I'm asking the others, is this intentional/documented behaviour of 
avfilter? is there a way to specify it to only do it in the 
end of the filter chain? Because if there is a way to ensure this, 
probably that is what the users would want, so I'm more than happy to 
change ffplay to work like that.

Subject: [FFmpeg-user] Video concatenation not working.
Message-ID: <CAK6GkD2VeXEb6DHDK2qapxrx8R7cis9ectZ29qud-dJ0fG2YNg@mail.gmail.com>

Hi,
I have two mp4 files that I am trying to concatenate with the demuxer. The
resulting video is just a blank green screen with some flicker here and
there. What am I missing ?

The list.txt does have the two video files I wish to concatenate. If it
helps, the first one is a video generated out of a png image.

Here is the command and result:

user at host:~/mp4$ ffmpeg -f concat -i list.txt -c copy output.mp4

Not once explained, but trying to find in the docs from cold with no obvious link or change log relating it to what went before is not so straightforward for someone who doesn't keep entirely up to speed with project. Completely appreciate the difficulties in keeping very high level documentation with a (brilliant) project like this but when things change at the pace they do, but when they do change it sometimes isn't immediately obvious until something stops working. I guess it would be good if the command line output could indicate deprecated switches and indicate the new method but understand that could be a huge undertaking.

Ok, I ran the command with the changes as above. I'm keeping the old workflow of separate video and audio encodes, then mux afterwards for now to minimise the room for introducing other errors in a single command

Below this I've included the output of a 0.7.13, this generates a valid IMX file. I've included ffprobe and mediainfo output for both incase it is of any use.

Many Thanks,

Steve

No, but we should probably extend the code (and adopt something
similar to ffmpeg -force_key_frames).

No, this also could be implemented.

Please provide ffmpeg -i output for the files in list.txt

(That is probably a bad idea, but unrelated.)

Sorry, I am not sure I understand:
Did changing -intra_vlc 0 to -intra_vlc 1 and 
-non_linear_quant 0 to -non_linear_quant 1 help or not?

And could you clarify if I can reproduce the issue (that 
the file is not correct) only with Mediainfo or is 
there another possibility?

Your changes work in that ffmpeg now runs without error and creates an m2v file but does not solve the problem the mux stage does not create an IMX file. Media info included as it shows the file codec is listed different to previous whereas ffprobe does not

I can see the problem elsewhere as FCP refuses to open the new encode, says it's an invalid file, QuickTime opens but won't play back, QuickTime inspector shows codec is not right and vlc likewise - the final output file has codec id of m2v1 not mx5p as before.

I think the mpeg2 encode works ok (but no direct way of checking) but the wrapping into the IMX mov fails to set the codec correctly. Old version makes no mention of m2v1. The new version also encodes at 50004 kbps, not 50000 Kbps though unsure as to why. Is this an issue that would stop the imxdump working?

New:    Stream #0:0(eng): Video: mpeg2video (4:2:2) (m2v1 / 0x3176326D), yuv422p(tv), 720x608 [SAR 152:135 DAR 4:3], 50004 kb/s, 25 fps, 25 tbr, 1200k tbn, 50 tbc 



Old:    Stream #0.0(eng): Video: mpeg2video (4:2:2), yuv422p, 720x608 [PAR 152:135 DAR 4:3], 50000 kb/s, 25 fps, 25 tbr, 25 tbn, 50 tbc

ffplay. I must say that the flicker is less and somewhat unpredictable. It
is the completely blank screen that is more worrisome.

Subject: [FFmpeg-user] Confusion with recording RTMP stream
Message-ID: <52A2AE06.5030302@pagestream.org>

Seems like a simple thing. I would like to record a live stream from 
http://weathernationtv.com/OnTV (their on-air live stream), but I can't 
seem to get it to work.

Using some product on Windows called MediaBox, it gave me this info:

url: rtmp://cp77659.live.edgefcs.net/live/0_c6zkpyg0_1 at 2781
app: live
flashVer: WIN 11,9,900,152

swfUrl:

tcUrl: rtmp://cp77659.live.edgefcs.net/live
playPath: 0_c6zkpyg0_1 at 2781


So I tried this simple command:

ffmpeg -i "rtmp://cp77659.live.edgefcs.net/live/0_c6zkpyg0_1 at 2781" temp.mp4

And got:

Any suggestions, or good tutorial on figuring this out? Thanks!

Check your rtmp stream with Akamai Flash Support Player
http://support.akamai.com/flash/.
It gives the same error there,

Try to do some screenshots or dynamic scenes - you will see it's
interlaced/progressive/telecined.

-segment_times, you need a recent ffmpeg version though.

I don't think you can concatenate two (very) different streams 
with -codec copy, at least not in a mov container.

Try to encode your png with -pix_fmt yuv420p -s 1280x720.

The idet filter can tell you but be careful it is not made 
for telecined input.

The performance hit is one issue, the fact that deinterlacing 
damages your input is second problem.

Try to avoid "-deinterlace", use "-vf yadif" instead.
(I find the -r 30 suspicious in your command, but 
maybe you know what you are doing.)

Ok. I will try as soon as I am close to my computer.

So, the mp4 from png turns out to be different from the other (original)
mp4.

As Carl Eugen said, it is not at all certain you can just concatenate
together streams that are so different. At the very least you would need to
chose the right time base, and the result would be variable frame rate,
which, unless I am mistaken, is not possible with FFmpeg's MP4 muxer.

The concat demuxer can not deal files with different streams. You need to
have audio in your first file too if you want it.

Subject: [FFmpeg-user] Pad real-time input stream when there is no input
 data available at this moment
Message-ID: <52A31585.2090307@lists.dedilink.eu>

Hey guys,

i am currently writing a live-streaming in node.js with ffmpeg and stuck
at some buffering issues.

- So what do i have?

The node.js-script, which manages the stdin source for the following
ffmpeg process (switch between live-stream and playlist-stream on the fly).

The ffmpeg-process, called encoder, which takes data from stdin and
writes them out in mp3 format to stdout.

 -ac 2
 -acodec pcm_u8
 -analyzeduration 5000
 -ar 48000
 -f u8
 -re
 -i pipe:0
 -ab 128k
 -ac 2
 -acodec libmp3lame
 -ar 44100
 -f mp3
 -flags2 local_header
 -strict -2
 pipe:1

- What is wrong with this bit of code?

As written above, the node.js script manages the stdin source for the
ffmpeg-process and therefor switches around live-streaming and
playlist-streaming (there is also an advertisement-streaming and a
silence-stream if none of these three streams are sending data).
Sometimes, the live-streaming source just freezes and the node.js-script
has to wait for a defined timeout to occur. When this timeout occurs,
the script disconnects the live-streaming source and connect the
playlist-streaming source on-the-fly. So far so good, but there is still
one problem: When the script is waiting for the timeout to occur (for
example 2 seconds), there is a gap between these streaming sources for
exact 2 seconds, which is also noticable on the output-stream of the
ffmpeg-process. Result -> The client needs to resync/rebuffer the stream
for another 2 seconds. This problem has been temporarily bounded with a
prebuffering of 25 seconds, done in the node.js-part which processes the
output of the ffmpeg process but only for about 13 timeouts and then the
client again needs to resync/rebuffer the stream.

- So what do i need to fix this issue?

I need some sort of example of a very complex (i think it is very
complex) ffmpeg-command, which is doing this:

When ffmpeg starts, start buffering a real-time anullsrc and pause the
buffer-processing for now.

When ffmpeg receives a chunk on stdin (over and over again), reset the
buffer to 0, pause the buffer-processing and reset the timer for the
timeout to 0.

When a timeout of a defined time (e.g. 2 seconds) occurs, resume the
buffer-processing of the anullsink-buffer so, that also prebuffered
chunks of anullsrc are being processed.


Is this somehow possible with ffmpeg or are these a bit too much
requirements for it?

PS: If someone wants to check out the code: http://github.com/Fusl/nodecast


Thank you for your attention!

Hi, Carl.

I am not sure about -r 30 myself. From what I had red it may make video
choppy, but what will be better way to ensure 30 fps output?

WBR,

Message-ID: <c039f628e6d2d8656c8dcb8924dfedab@aleksandrsolzhenitsyn.net>

I need to transcode a Sony mini-DV video to mpeg for use in a DVD.

In the past I used Kino to grab the video and then edit and export it 
to an mpeg format. Once that was done DVD Styler was used to format the 
appearance of the video and then create the DVD structure.

Having said that....I'd like to simply grab the video and then 
transcode it to mpeg suitable for using in DVD Styler.

Can you suggest a ffmpeg code line for transcoding from DV to mpeg?


Thanks,

Alek

Ok, I have run the encode on a smaller input file and put all the files on a wetransfer link. I have also performed the encode in the separate steps, and as a single command.

Interestingly the final output file is different depending on the method (this may be what you were referring to when you said it was a bad idea). Using the separate steps, the codec is listed as "m2v1" and this file will not playback in any media player (only mediainfo and ffprobe will interrogate it). Using the single step, it is listed as "mpeg2video" and this file will playback in Quicktime and VLC (though Quicktime 7 lists the codec as "MPEG-2 Camcorder Video"). It is not recognised as an IMX file though and the full 720 x 608 resolution is visible in quicktime rather than the top 32 lines (the VBI lines) being hidden as they would be after an IMX encode to produce a visible 720 x 576 resolution. Would this indicate the imxdump bitstream filter is having no effect on the output?

I've looked at imx_dump_header_bsf.c from 0.7 and from 2.0 and there is no difference between the two. Trying to use a codec other than mpeg2video it throws an error: [mov @ 0x8088dcc20] Tag mx5p/0x7035786d incompatible with output codec id '25' (dvcp)

The files (159MB total) can be downloaded from wetransfer: http://we.tl/DX3ENjmJqT

Have you tried anything yet? You could start out with:

ffmpeg -i input.dv -target pal-dvd output.vob

Offtopic: I just noticed your email address. I recently read "One Day in
the Life of Ivan Denisovich". I found it interesting that Khrushchev
authorized the publication.

Would it work this way too...?

ffmpeg -i input.dv -target ntsc -dvd output.mpeg

Possibly, but I know nothing of your input. You'll have to change
"-target ntsc -dvd" to "-target ntsc-dvd". See the -target option in the
docs for a list of all target types.

"-target ntsc -dvd" was merely an error on my part when entering the 
text in these various emails.

As to the "input"- should I do a "ffmpeg -i Inputfilename.DV" to get 
the information?

Thanks

I understood your original question as "I don't want to overwrite 
my existing FFmpeg installation" and I tried to explain that you 
don't have to *install* FFmpeg (I never install), it is 
sufficient if you *compile* FFmpeg (I compile several times a 
day) because the default compilation produces an executable that 
you can run from whereever you want (including the build directory).
When you are happy with the new executable, copy it into a 
directory of your choice (like /usr/local/bin) under a name of 
your choice (like "myworkingffmpeg").

I may misunderstand but the only supported "install" is 
the one from http://ffmpeg.org/download.html

Please do not top-post here, Carl Eugen

I didn?t access your video, please tell me how. In the meantime, I used
your process to rip a DVD so I could try some things. I couldn?t use .mkv
as the name extension of the source file, but once I changed it to .mpg, I
could use the following. The output is OK from beginning to end even when
I performed it on the full 90-minute title. Mine was an old 4X3 source.

Subject: [FFmpeg-user] balancing image generator and FFMPEG 'loop'
Message-ID: <b8e58b14209000e4c759af56269f76a8.squirrel@localhost>

Dear All ...

I'm trying to get a cam snapshots and stream it out to ustream

my solution is based on two things
1. Snapshot downloader :
It's based on
https://github.com/jpmeijers/pisstvbeacon/blob/master/AircamDownload.py ,
and I make it to send request in loop.
Currently with this script, new image will be generated each second
(more/less).

Each image have a sequence number in it's name : pic01.jpg --> pic99.jpg

2. Streamer :

ffmpeg -re -loop 1 -f image2 \
    -i "/var/run/snapshots/inaxtower/pic%02d.jpg" \
    -r 10 -vcodec libx264 -pix_fmt yuv420p \
    -f flv "rtmp://1.XXX.fme.ustream.tv/ustreamVideo/XXX/USTREAM_KEY
flashver=FMLE/2.50(compatible;0FMSc/1.0)"


Currently the result looks like 'rushing'.

You can check my current result at : http://www.ustream.tv/channel/16636088
Please put attention on the clock stamp at top-left of the movie, looked
weird.

My Question is :
    How to balance image generation rate (script #1) with the ffmpeg rate ?
    I mean, what number should I put for image generation rate? ,and
    what number should I put for the value of ffmpeg '-r' ?

Sincerely
-bino-

You do generate 1 frame every second. So framerate is 1 or in ffmpeg terms ?-r 1?
Hope you now understand how to balance or NOT get rushing.

I don't know how you can get access to incoming, but thanks for the shot. My method works for most dvds, this one source is the exception rather than the rule.

IIUC, combmatch=none will label no frames as interlaced. So you wouldn't get any errors like I am getting no matter what. I added that option to my command and it didn't complain anymore, but it did still produce interlaced frames. 

I tried changing the extension to mpg and I had the same output as before. I had assumed ffmpeg was smarter than that.

Subject: [FFmpeg-user] Exporting Images with Subtitles
Message-ID: <CAPX8AsFfqvTZ7vwZ-8yzqHzZnFf0Ucg6EM8DWtc1BMAVk65nrQ@mail.gmail.com>

Currently I'm considering on making a video w/ subtitles to image w/
subtitles application and am wondering if there is a way to pretty much get
an idea of what the resulting product would look like with only ffmpeg.
So is there a way to also output subtitles onto images when creating them.
I'm basically creating a bunch of thumbnails with:
"ffmpeg -i v2.mkv -f image2 -vf "select=gt(scene\,0.5)" -vsync vfr
 out%02d.png"
However, subtitles are not being added to the images.
I tried adding "-c:s copy" and also "ass=subtitle.ass"; with the former I
just got extra blank images and with the latter it errors and tells me that
subtitle.ass does not exist (media info says they're ssa subtitles).
If i manually extract subtitles.ass from the video and use the latter
command then I get some blank images again.
So is there an easy way of doing this?
Ideally I would take a image whenever a subtitle is displayed but I do not
believe this is easily done even with a combination of programs and is what
I will probably end up building if I like the early results of something
simple like this.

I'm not clear what the problem is, which is why I was asking. I can't

Can anyone watch this stream? I know it worked before...

I don?t think the command will be of any use whatsoever without the
conversion to 24 fps (fps=fps=24000/1001). No interlaced frames remain
when you use that, do they?

Subject: [FFmpeg-user] 3 points jpeg to timelapse issue
Message-ID: <4028362F-22BB-4FE8-A394-C19896A9383D@gmail.com>

Hi
Having a few issues converting a jpeg sequence to adequate video. Any form of guidance appreciated.

Frontmost problem is the great loss in quality/depth (huge visible contrast increase) that occurs when applying :
	ffmpeg -f image2 -r 12 -i FILE%04d.JPG -r 12 -s 864x648 -vcodec libx264 output.mp4	(original files are ~1.1MB, 2592 x 1944 jpegs)
also tried
	ffmpeg -f image2 -r 12 -i FILE%04d.JPG -r 12 -vcodec copy output.mp4 [with previously scaled jpegs ? which isn't practical at all for me?]
with same problem.

I'm on mac os 10.8.5. A Quicktime conversion (H.264 multi-pass) gives a satisfying output, no significant contrast/range/depth loss, just blurr. Yet Qt isn't practical for me
I'm sure this is documented somewhere, so forgive me for not digging further, but I can't seem to get a 2-pass with ffmpeg to work in this case.
	ffmpeg -f image2 -r 12 -i FILE%04d.JPG -pass [[1/2]] -r 12 -s 864x648 -vcodec libx264 output.mp4	???
What would the correct syntax be?
And could a 2 pass run solve my quality issue? or have I got it wrong from the start?

Secondly, once I get the settings right, I need to process the content of multiple folders in the form 101MEDIA, 102MEDIA, etc.
Any way to tell ffmpeg to do this all at once, (190GB of data, and counting?), the output being 'one' big MP4 file?

Thanks for reading and any hints.
Regards,
J

(Complete, uncut console output missing.)

You neither provide a bitrate nor a constant quantizer so 
a (small) bitrate is chosen.

I haven't seen any admin get mad because of a signature. Signatures are
not forbidden, but they are generally not useful here and should be
omitted, if possible, and trimmed from replies.

Please note what is more annoying than a signature is top-posting which

I already use such a tool.
One home-made, ffmpeg segment and multicat.
All this 3 tools make ts file without cut in a middle of a frame, none 
of them are very good for me (start with a keyframe AND  be accurate 
with the duration).

I'll start another threads to explain/speak about another point with 
these files.

I take mjpeg_streamer as work around.

So my solution currently consist of :
1. Snapshot downloader.
2. mjpeg_streamer ..
3. FFMPEG to restream from local mjpeg streamer to USTREAM

I Really appreciate your help.

Your snapshot creation needs to be 10 jpgs per second if you want to streamer to output with ffmpeg ?.. -r 10 ?. to avoid rushing.
They need to be the same.

The 'decimate' filter after fieldmatch would take care of the frame rate coversion, but it just throws out the extra frame, so it wouldn't change the fact that fieldmatch was labeling frames as interlaced, but yadif wasn't deinterlacing them.

Subject: [FFmpeg-user] corrupted mp4 encoded from images sent from a pipe
Message-ID: <CANdLC8V0Hi-OJo1VF4q1hQpcEPUvih75vEKuBvPkBzPEw=vN6A@mail.gmail.com>

Hi,

I'm encoding mp4 from images sent from phantomjs over a pipe.
The mp4 is corrupted and doesn't play in FF and Chrome.
After repairing it, it plays fine.

Is it possible that phantomjs doesn't gracefully ends the stream?
At the end I'm getting an error:
pipe:: Input/output error

This explains how to send images from phantomjs to stdout:
https://groups.google.com/forum/#!topic/phantomjs/wluVGGjhL90

Command used to create the mp4:
./phantomjs test.js | ./ffmpeg -y -c:v png -f image2pipe -r 10 -i - -c:v
libx264 -pix_fmt yuv420p test.mp4

Command used to fix the corrupted mp4:
./ffmpeg -i corrupted.mp4 -c copy repaired.mp4

More info is listed below.

Thanks

phantomjs test.js
--------------------------------------------------
var page = require('webpage').create();

page.clipRect = { top: 0, left: 0, width: 900, height: 800};
page.viewportSize = { width: 900, height: 800};

var url = 'http://dl.dropbox.com/u/621993/voronoi/voronoi.html';
var frames = 100;

page.open(url, function(){
    setInterval(function(){
        page.render('/dev/stdout');

        if( frames == 0 ){
            phantom.exit();
        }

        frames--;

    }, 100);
});

What happens if you save the output of phantomjs to a file first?

I've generated images with phantomjs instead of sending to the pipe.
I have img001.png, img002.png...
I'm calling the command:
../ffmpeg -r 1 -pattern_type glob -i '*.png' -c:v libx264 -pix_fmt yuv420p
out.mp4

The video is still corrupted.

../ffmpeg -r 1 -pattern_type glob -i '*.png' -c:v libx264 -pix_fmt yuv420p
out.mp4

(Why did you change from image2pipe to glob?)

Could you explain what is corrupted / how do you 
know it is corrupted?

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

I saw this command on the wiki.
Tried other variations and this worked.
I'll be happy to check other commands if needed.

The video doesn't play in FF and Chrome.
Maybe corrupted is not the right word but I thought that was the issue when
using pipe with phantomjs.

In this stackoverflow question someone says he got the same "pipe::
Input/output" error

Subject: [FFmpeg-user] ffprobe, show_entries.
Message-ID: <1386683490505-4662660.post@n4.nabble.com>

Hello

I am using ffprobe to get some information, However I want to limit what is
returned.
So far I am able to easily select what I need from format with
-show_entries format=duration,size

However, I want to also get the video stream information using
stream=width,height

The problem with just this, is that it will return all stream wrappers(with
blank info) and then the 1 correct wrapper with width and height settings.

>From what I see from some examples, the video stream is always set to index
1 inside the streams wrapper, How can I set the search to return
width,height from just this section?

Thanks in advance.

I want to set the input sample format to s32 but I failed to change it from its S16_LE default format.

Am I doing something wrong or did I have stumbled onto a small ffmpeg bug?

Hi,

I have found the answer:

I had to change -sample_fmt s32 in

ffmpeg -f alsa -sample_fmt s32 -i hw:1,1,0 -strict -2 -acodec aac -ar 48000 -b:a 64k out.aac

to -acodec pcm_s32le for

ffmpeg -f alsa -acodec pcm_s32le -i hw:1,1,0 -strict -2 -acodec aac -ar 48000 -b:a 64k out.aac

Subject: [FFmpeg-user] interactive arrow keys
Message-ID: <CAN9oDtd1mnUr1TCqRvcD8mRKeykKuzk_rq9tD0Pw6dL9KDp=hg@mail.gmail.com>

Hi,
I'm sorry if this is a newbie question but I couldn't find an answer
through several differently-worded searches.  I use Linux (Arch) and run
ffmpeg from the command line.  Sometimes I will accidently press the back
or left arrow key and the output of ffmpeg changes to what I guess is
extra-verbosity-mode or something, in which multi-colored details print in
the terminal as it encodes.  I would like to know how to get out of that
mode, back to normal ffmpeg, non-verbose output.  I was thinking that in
the long run it might make encoding a little slower since it is using some
processing to print output.  I've also noticed that pressing the forward,
right arrow key puts it in some kind of command entry mode.

I guess the processing loss is probably negligible but I would still like
to be able to go back to standard output.  I like to be able to quickly
check the progress and the screen changes too fast with this verbose
stuff.  Also, I'm a little curious what commands I could enter with the
right arrow key thing.

Thanks for any help,

E

There is something like an inline help. Just press ? and ffmpeg will
print it out..

Example for version N-58852-g4dfc8f6 built on Dec  7 2013 13:24:02:
key    function
?      show this help
+      increase verbosity
-      decrease verbosity
c      Send command to first matching filter supporting it
C      Send/Que command to all matching filters
D      cycle through available debug modes
h      dump packets/hex press to cycle through the 3 states
q      quit
s      Show QP histogram

With left arrow key, you are actually writing the escape sequence ^[[D
to ffmpeg and ffmpeg ignores all keys until it matches something usable
(in this case D).
So...
Up:    ^[[A
Down:  ^[[B
Right: ^[[C (Matches Send/Que command to all matching filters)
Left:  ^[[D (Matches cycle through available debug modes)

I think in_picture->pts is not increasing quite well

I also don't undestand why it is changing my image to yuv444p ,according 
to line one line from log
Input stream #0:0 frame changed from size:279x181 fmt:yuvj420p to 
size:640x480 fmt:yuvj444p
I never asked ffmpeg to convert in pixel format to yuv444p, i asked for 
yuv420p

I feel there is no problem in image, because in list of image i gave 2nd 
and forth image same,
if it has converted yuv444p to yuv420p then nnext time when same image 
come, it should
do same conversion properly

Please point me some document, so that I can make my timing 
understanding good, It look like
these concepts of mine are weak

If all image are in yuv420p format already, then frame drop is not observed

I consider this impossible. If you are referring to what we usually
understand under "mp3", this is an audio format. You cannot "convert"
video to audio.

If you are looking for a filter which can create a sound which
"represents" the visuals in your video, I believe ffmpeg has no such
filter:
> ffmpeg -filters | grep -F 'V->A'

I think the other way is possible:
> ffmpeg -filters | grep -F 'A->V'
 ... avectorscope     A->V       Convert input audio to vectorscope video output.
 ... showspectrum     A->V       Convert input audio to a spectrum video output.
 ... showwaves        A->V       Convert input audio to a video output.

why?

so what

says who?

the video has a seperate audio- and video-stream
if hwat you are saying would be true options line -an
for skip the audio stream of a video would be impossible

ffmpeg -i yourvideo -f mp3 -acodec libmp3lame youraudio.mp3

even the other direction works but while technically nothing
is easier than take the audio-stream and convert it to whatever
while ignore the video you need a image-loop for the length
of your target video - been there, done that, implementation
in a php-cli-wrapper took around 1 hour

	merge trancoded file without gaps

Hi,

I attempt to achieve this with an UDP Mpeg/Ts input stream :

1- Generate 5 minutes length .ts files from this stream, for shirt time storage purpose.
I've tested multicat, ffmpeg segment and some homemade tools, none of them make TS files starting with a KeyFrame (IFrame). This is normal.

Joining two produced .ts files to a new one with the ffmpeg concat muxer or a cat command works great, no gap, no scratch, no artefact.

2- Generate 5 minutes length .mp4 (h264/aacplus) files from this generated 5min .ts.

I use this ffmpeg command :

ffmpeg -i <INPUT_5MIN_TS> -y -movflags +faststart -c:v libx264 -vf yadif=0:1:0,scale=-1:288 -vprofile baseline -preset fast -crf 18 -maxrate 450k -bufsize 450k -pix_fmt yuv420p -c:a libaacplus -ab 64k -ac 2 <OUTPUT_5MIN_MP4>

(I try with and without -copyinkf)

All generated files (.ts, .mp4) must join smoothly (without any gaps or cracks) with subsequent one to produce a new file (eg: 05to10.mp4 | 10to15.mp4 | 15to20.mp4 => 05to20.mp4 ).

I've tried the technic described in this post https://trac.ffmpeg.org/wiki/How%20to%20concatenate%20(join,%20merge)%20media%20files to join .mp4 files

ffmpeg -i 05to10.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate1.ts
ffmpeg -i 10to15.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate2.ts
ffmpeg -i "concat:intermediate1.ts|intermediate2.ts" -c copy -bsf:a aac_adtstoasc 05to15.mp4

Sadly, the output "05to15.mp4" contains video artefacts around the cutting point (~4 min 59 sec).

Is there another method to cut the ts stream or tricks to prevent this artifacts ?

Anybody can help me to solve this problem ?

I use this version :

the opposite is true

the question was "how can i convert video 2 mp3 file? "
at this point there is no command line or console output
why? because there was nothing tried at all, only asked how

the problem is blind answering "you can't convert a video
to a audio-file" which is technically at least in context
of how ffmpeg works nonsense

Hi again
Where I could really use some expertise is with the processing of multiple folders, since ffmpeg FAQ and google aren't helping.
My camera stores FILE0001.JPG to FILE0999.JPG in folder 101MEDIA, than resets filename and fills 102MEDIA, etc.
Can someone please point out the BASH way to symlink all files (300'000 and counting) as a single sequence in a single directory, or a way to pass all to ffmpeg according to capture time/creation date, or any command, for that matter, that would allow me to get a single output file out of this mess?
Thanks a lot for any help.
Regards,
J

I consider this impossible. If you are referring to what we usually
understand under "mp3", this is an audio format. You cannot "convert"
video to audio.

If you are looking for a filter which can create a sound which
"represents" the visuals in your video, I believe ffmpeg has no such
filter:
> ffmpeg -filters | grep -F 'V->A'

I think the other way is possible:
> ffmpeg -filters | grep -F 'A->V'
 ... avectorscope     A->V       Convert input audio to vectorscope video output.
 ... showspectrum     A->V       Convert input audio to a spectrum video output.
 ... showwaves        A->V       Convert input audio to a video output.

As Moritz already pointed out, the term "convert video to mp3" does not
really make sense. This also explains why you didn't find anything with
that search phrase.

What can be assumed (as Harald already mentioned) is that you would like
to extract the audio from a video and save that in MP3 format?

If this is the case, you could try to rather search for something like
"extract audio from video"?

An update about my test.

Using this command :
ffmpeg -i udp://x.x.x.x:xxxx -force_key_frames 1 -c:a copy -c:v copy -map 0 -f segment -segment_time 300.000 -segment_time_delta 0.005 /tmp/segment/file%03d.ts

I can generate TS file witch begin with a I-Frame.

"It depends?" on what you want. 2-pass is generally used if you're
targeting a specific output file size.

If you just want a certain quality, and reaching a specific file size is
less important, then use -crf. Range is a log scale of 0-51. 0 is
lossless, 18 is sometimes considered to be "visually
lossless" (depending on the input, the viewer, other encoding settings,
etc), 23 is the default, and 51 is the worst quality.

Start with 23 and increase or decrease the value until you find the
highest value that still provides an acceptable quality. Use this value
for the rest of your image sets.

If you're going to upload to a video service then try 18 since they
will re-encode anything you provide. (You can try 0 too and the size
difference may not be too significant depending on your input such as
easy to encode, fairly static inputs).

I can provide some examples, but your complete console output for at
least one of your commands is missing. My answer will depend on this
information.

Default for libx264 is "-crf 23" (ridiculously ancient builds excluded).

If the stall happens exactly every 30 seconds, it is most likely from the
linux kernel, which does a dirty page writeback if a page gets older than 30
seconds.
If the amount of memory written in 30 sec is to big, the writeback may last
significantly longer the a frame (33 msec) and you lose frames.

You can try either


for a writeback every second (possibly a even lower value)
or, if you have lots of RAM (more than the size of the screencast)



for completely avoiding writeback fpr 10 minutes worth of screencast.

Yes, this is the expected behavior.

When you select -show_streams, you select all stream local entries and
their subsections, and is the equivalent of "-show_entries streams".

You can explicitly disable the elements in subsections, by doing:
"stream_tags=:stream_disposition="

(see ffprobe -sections for the complete list of sections).

or enabling through -show_entries only the local entries you're
interested in:

ffprobe -select_streams v -show_entries format=size,duration:stream=width,height -print_format json INPUT

Quoting the manual:
|If section name is specified but is followed by no "=", all entries
|are printed to output, together with all the contained
|sections. Otherwise only the entries specified in the local section
|entries list are printed. In particular, if "=" is specified but the
|list of local entries is empty, then no entries will be shown for
|that section.

Subject: [FFmpeg-user] Advice: Running FFMPEG under VMware,
	performance tuning, config
Message-ID: <52A8E9C3.8040801@gmail.com>

We have been running FFMPEG on real-iron hardware for a while; now, 
starting to run it in VMware VMs -- which is a game changer in terms of 
flexibility; however, I have noticed a performance degradation -- which 
I partially expected.

Understanding VMware's scheduler and how it handles CPU bandwidth is key 
- for example, if you have 2 cores and a max CPU speed of 3ghz, the 
speed is divided between the two cores.  So, does that make two cores 
more efficient than one, at full speed?

In any case, we need to expand our use of this tool under virtual 
environments and I'm wondering if some of you more-experienced folks 
might have some tips, advice about how to maximize performance of FFMPEG 
under VMs.   VMware is our primary system, but I am going to take a peek 
at Xen for some development/testing.

Is it correct to conclude that the configuration file needs to be

This is old. Please compile from git master or use a recent build:

Why --disable-decoder=aac --disable-encoder=aac? You disabled native
AAC decoding and encoding, but you are also not using an external AAC
library resulting in no AAC decoding or encoding capability.

--enable-pthreads and --enable-postproc are default (at least with
recent ffmpeg) so you don't need these.

I'm guessing that this is AAC audio, but you disabled the AAC decoder.

You need to not use --disable-encoder=aac.

> Where is the configuration file to be found?

Changing the configure file will not change anything. You need to
re-compile ffmpeg without --disable-encoder=aac or use a recent build.

Subject: [FFmpeg-user] second pass combined with volume detect
Message-ID: <52A9A7B1.1000605@orange.fr>

Hi
I am doing encoding from vob to flv (avc/aac) 2 passes
using a git static built on 21013 dec 6
my command line are
ffmpeg -i input_file -vcodec x264 -b:v value -r:v value -vf 0.9375 -g 
value -an pass 1 -y output.flv
ffmpeg -i input_file -vcodec x264 -b:v value -r:v value -vf 0.9375 -g 
value -acodec aac -strict -2 -ab value -ar value -ac value pass 2 -y 
output.flv

then I have to restart 2 ffmpeg runs one to figure out what is the sound 
level , and then correct it
my command lines are
ffmpeg -f lavfi -i movie=input_file,volumedetect -f null -y logfile
calculated_volume = from the logfile
ffmpeg -i input_file -vcodec copy -acodec aac -strict -2 -ab value -ar 
value -ac 1 -af calculated_volume -y output_file

would it be possible during the second passe to include a volumedetect ?

I am presently doing so using -f lavfi -i 
amovie=<inputaudiofile>,volumedetect -f null
there are some "collission" betwen -f options
i do not succeed to mix both , what would be the correct syntax

thanks
jacky

Subject: [FFmpeg-user] png to mp4 conversion error.
Message-ID: <CAK6GkD1sYuigDbH=kW+Fz8KDvRcNqi_Ddm7mJTD8n9aqiyzoYw@mail.gmail.com>

I have a png file that I want to convert to a video of n seconds. These png
files were created from the convert (imagemagick) command where the input
is a couple of lines of text. The output is a png file with the text in
white, background black, Helvetica font and size 16. The ffmpeg command
(shown below) converts most images correctly. For others, the conversion
does not happen.

It seems, there are some parameters of png file that need to be set
correctly to allow successful conversion. If so, what are they ? And, would
you know how to set them when using the convert command ?

That hasn?t been my experience at all. The frame rate of the output may be
the same, but unless the filter chain and all other options are the same,
the encoding results might be entirely different.

The identify command does show difference but, I am not sure, I understand
them. For example, ffmpeg says, "unspecified pixel format". But, the image
properties do not list anything specific to pixel format. Apart from that,
the image that does not transcode successfully shows a histogram in its
output whereas, this histogram is not seen with the image that works.

I'm not sugesting that it would be identical, but it seems that the problem is between fieldmatch and yadif so tacking ,decimate onto the end would not change if yadif caught the frames. I tested and the I get the "still interlaced" frames at the same places.

Frame #8158 at 272.205 is still interlaced time=00:04:31.96 bitrate=2607.8kbits/s??? 
[Parsed_fieldmatch_1 @ 0x306d9d4f20] Frame #8159 at 272.239 is still interlaced
[Parsed_fieldmatch_1 @ 0x306d9d4f20] Frame #8160 at 272.272 is still interlaced

Furthermore, if decimate does its job right the frame rate is already 24000/1001 since it was 30000/1001 and decimate drops every fifth frame. I checked and the decimated version has a frame rate of 23.97. So I don't thinking adding the fps filter at the end should change things. Also, I just checked, and it doesn't. Same output and error.

Subject: [FFmpeg-user] Performance tuning FFMPEG under VMware
Message-ID: <52AA0D97.4060804@gmail.com>

We have been running FFMPEG on real-iron hardware for a while; we're now 
trying it under VMware VMs.  I've noticed a performance degradation -- 
which I partially expected.

There are lots of folks out there running FFMPEG like this, in large 
transcoding farms (Yahoo/Google?) so I'm hoping for some really useful 
information.

If you have 2 cores and a max CPU speed of 3ghz, the speed is divided 
between the two cores.  So, does that make two cores more efficient than 
one, at full speed?


Thank you in advance...

Subject: [FFmpeg-user] Converting
Message-ID: <CAMfuUJE_yK4+PjhyssZjwR_TkCipLwu_PrJ-NaNcqswXaT60vQ@mail.gmail.com>

Hi there.
I want to convert recorded tv files into mkv. I record some kids movies on
my "Edision vip" sattelite receiver. It is stored as separate trp files. Is
a record about 3,5 gb it is stored into:
data00.trp
data01.trp
...
data06.trp
each file is 700MB.

What I want to do is to make one file of 3,5gb and convert it into mkv
files format that supports hd video resolution and multi-audio channel 5.1.
I want to store it onto my nas. The kitchens tv can not playback trp files
but mkv files.
I like to do that with ffmpeg and not with any other software. I am looking
for a solution that match it in one step because I have no time to wait in
front of the pc to wait. If its start then it can take time to convert...
Who can help??
Thats in advance.

Hello

Thanks for your answer, However I failed to make changes to my question when
I posted the screenshot image of cmd ffprobe.(hence why the screenshot
doesnt show *disposition* entry)

I applied the same query you suggested with returns what is in the
screenshot.
/ffprobe -select_streams v -show_entries
format=size,duration:stream=width,height -print_format json INPUT /
And this query does fix the return of disposition, But this query still
leaves empty wrapper *programs*, along with empty tag entries inside
*streams* and *format*

Why are these being returned?

Thanks in advance.

Hiya

What kind of file is this? Can you post what ffprobe says about it (or
just run "ffmpeg data00.trp", it will error but still show the
interesting information.

When you select a section to print, all the containing sections are
enabled as well. In this case stream is contained in a program (a
program can contain multiple streams), and thus the container is
shown. It was meant to show streams informats from the programs
section, rather than just reference them, and this is a side effect.

About the empty tags container, yes that's probably a bug we should
fix.

Note that from the parsing side this should not cause problems, since
you can skip the unwanted data when processing the JSON. Is that a
problem for you?

You can try the command below convert the file to mkv first: 
ffmpeg -i data00.trp -q:v 0 data00.mkv

Then use concat filter to join them together:

I've managed to do this with xdcam and imx50 codecs in a mxf container with

When you say "select a section to print", You are referring to query
/-show_entries/? rather than /-select_streams v/?
/select_streams v/ does not return *programs* wrapper for me(when queried
without /-show_entries/), So it seems /-show_entries/ is what is bringing
the programs wrapper into view.

Regarding tags wrapper, Your right I can just parse the json and remove, I
wanted to know why it was being returned as I spent alot of time going
through many different combinations and strings to remove it without
success(im new to ffmpeg). 
So thanks for answering this.(I might have carried on more hours if you
didn't reply)

(Overall when you find much free time, its probably best fixed, better to
not be returned in the start than have to manipulate json)

Thanks!

PS - From another angle, Is there anyway I can force tags to not show?

Here's a sample of video converted to mp3 and then back. http://www.youtube.com/watch?v=n1-xx1x6PnQ
I did this by feeding rawvideo into an mp3 encoder disguided as rawaudio and then converting it back to show the effects of lossy audio encoding on video data.

Subject: [FFmpeg-user]  Questions about PTS/DTS shifting
Message-ID: <CAHss8oF1H-GDw9bQr6VJWQ9yB9ydGsLguY8qmVLORs8BLbqP0A@mail.gmail.com>

hello,
I have this theoretical question:

Suppose a video with 2 tracks a/v (25fps, uncompressed so that pts=dts)
made like that (timebase is 1/1000 for both tracks):

first video pts = 40
first audio pts = 72

I would like to reach at least one of the following goals:

A: Shifting one track to 0 keeping sync with audio:
first video pts = 0
first audio pts = 32

B: Using padding (to keep sync), having audio pts=video pts
first video pts = 40
first audio pts = 40

C: This would be the best. both pts starts from 0 with sync.
first video pts = 0
first audio pts = 0 (with padding)


How to do that with a single command line and without having to previously
parse file to know first_pts values?


With [a]setpts filters I could shift timecodes but video filter don't know
anythig about audio pts, so I need to know pts values previously.

With areasmple:first_pts=x I have to know first video pts.

Any suggestions?

Thanks,
MB

Tags issue should be fixed, program streams issues would break
compatibility with the old scripts.

Again, I still fail to see which is your practical problem, since once
you have the JSON you can edit its content in your scripting
environment.

Any
 ideas on why frames are being dropped? I really think that there should
 be the correct frames from the teletext engine to keep the overlay 
system running.

There are a number of possible reasons; they mostly boil down to the
timestamps of the subtitles being out of sync. If you can not make the
source sample itself available, you can try to provide the following
information:

* The first few video and teletext packets, as shown by ffprobe
  -show_packets.

* The first few video and subtitles frames, as shown by ffprobe
  -show_frames.

* The first few video and overlay frames inserted in the filter. For that,
  use the showinfo filter:

  -filter_complex "[0:s] showinfo, scale=1280:720 [sub] ; [0:v] showinfo
  [vid] ; [vid][sub] overlay"

According to the manufacturer, the TV can play MPEG4 SP/AP, which is
different from MPEG4 DX50. I suspect this might be the problem.

Any hints on how to solve this issue?

Hi.  I'm trying to convert an AVI file that is compressed with ffvhuff into another
AVI file that isn't compressed with ffvhuff (rawvideo).  The output file is
blue-shifted.  Everything looks blue.  Here is the ffmpeg command:

Constructive advice, not criticsm:

But you guys keep answering the same questions over and over
again.  Why not answer the question once, document it fully, put
it on the wiki, and then when someone asks, just point them to the
answer?  Better yet, the Wiki is searchable, unlike the mailing-list
archives.  Isn't that better?

Because complaining is cheaper, and anybody can do it.

This is apparently (I am still searching for an 
"official" sample) a bug in MPlayer, work-around is 
to add the following to your mplayer command line:
-vc -raw422P,
Or the following to your MPlayer config file:
vc=-raw422P,

Third-party software is not supported here.

I'm not familiar with this extension, but perhaps you can contact the
author and have them provide a sane binary (I'm assuming a binary is
being distributed ? I didn't look), or maybe you can replace it with
another build, such as from:

There is no longer a problem.

Im only speaking about a trivial issue of handling returned data efficiently
in one place or the other, not both.
(which you addressed as a possible bug fix, I should not have re-brought it
up, sorry)

Thanks for your help!

Message-ID: <CALE9GBMTC8ujMGQR+PYYW3GD-17p4ORe1_arMu74MXVnsgLP2w@mail.gmail.com>

Hi,

I have a video, movie.avi, which will play on the VLC player but won't play
on a Samsung UN26EH4050F LED TV.

When I use ffprobe I get the following data.

Input #0, avi, from 'Reptilicus-1961.avi':
  Metadata:
    encoder         : Nandub v1.0rc2
  Duration: 01:21:30.31, start: 0.000000, bitrate: 1191 kb/s
    Stream #0:0: Video: mpeg4 (DX50 / 0x30355844), yuv420p, 512x368 [SAR

    Stream #0:1: Audio: mp3 (U[0][0][0] / 0x0055), 48000 Hz, stereo, s16p,
157 kb/s

According to the manufacturer, the TV can play MPEG4 SP/AP, which is
different from MPEG4 DX50. I suspect this might be the problem.

Any hints on how to solve this issue?

Thanks in advance,

Gustavo J. Mata

Do you have a sample (from the manufacturer) that is known 
to play? If yes, please provide ffmpeg -i output (uncut) 
for that sample.
(DX50 == MPEG-4 ASP)

If I understand you correctly DX50 is the same as  MPEG4 SP/ASP This would
suggest a bug in the TV software.

I do not have a video sample from the manufacturer. I will ask for one.

Thanks,

I do not understand this, what is not documented?

http://ffmpeg.org/documentation.html

It's a pretty comprehensive resource of ffmpeg's features. What isn't
in there can be found with google - for instance, x264 encoding is
largely down to x264, it would be wrong to document x264's features
here - how to access them should be (and it is..)

Cheers

The problem is that it's just a list of features. Carefully writing down the names of all the things that a program does is not adequate documentation. There is almost no usage information. I mean, I'm a reasonably experienced computer user, and I'm not sure what you mean by:

ffmpeg [global_options] {[input_file_options] -i ?input_file?} ... {[output_file_options] ?output_file?} ...

There is no basic introduction to typical tasks, examples, definitions of terms, or anything of that sort.

This is how you document commandline software:

what exactly do you not understand there?
[] encloses optional arguments
input_file and output_file is pretty clear

this is the standard convention *any CLI software* on this plant is using for help

Subject: [FFmpeg-user] jpeg2000/libopenjpeg lossless?
Message-ID: <52AF89B7.3070904@das-werkstatt.com>

Hello,

I'm currently drafting an article about containers and lossless codecs
for long-term video archiving [1].
During my speed/size codec comparison tests, I couldn't manage to
configure libopenjpeg to produce a lossless output video (checked with
framemd5).

Does anyone know which parameters do I require to encode JPEG2000
lossless using libopenjpeg?
(Yes, I did try to google)
"-qscale:v 0" (which works for dirac/libschroedinger) doesn't work with
libopenjpeg.


Thanks in advance,
Pb

Subject: [FFmpeg-user] Setting 'crf' option when converting with ffmpeg
Message-ID: <CAK18DJW=GM8zPUsYMCBEN+KiPXP0LftW9CCBP7Av=zpw1j_3Yw@mail.gmail.com>

I have a H264 encoded file that I try to convert to a mjpeg format.
That's the command that I issue and its output:

The red written text is the problem that I don't know how to deal with. Can
anybody tell me how to deal with this problem? I want to specify the "crf"
for this conversion because the quality resulted is very bad in a few
specific files. Why does "crf" does not take effect when I specify it in my
scenario?

crf is an option when using c:v libx264 NOT with c:v mjpeg

It is lossless by default.

Hm... Then there's something wrong with my build.

It also plays back faulty using ffplay: luma is correct, but the color  
information seems displaced and wrong.

Use -qscale 2 for best quality, higher values for lower 
bitrate.

I am getting below mentioned problem..

yasm not found, use --disable-yasm for a crippled build

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

Which configure line did you use?

> yasm not found, use --disable-yasm for a crippled build

For which architecture are you trying to build. arm or x86?
If you want to build for arm on a x86, you have to tell 
configure which compiler to use with the --cc option.

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

Hi Harry

I think while executing, you don't have privilege to set the stack 
limit, if you are already trying with
root user, then please look whether your linux support the changing the 
stack limit, I remember
some older version of Linux were not having this option

copied from manual
         RLIMIT_STACK
               The maximum size of the process stack, in bytes.  Upon 
reaching this limit, a SIGSEGV signal  is  generated.   To  handle this  
signal,  a
               process must employ an alternate signal stack 
(sigaltstack(2)).

               Since Linux 2.6.23, this limit also determines the amount 
of space used for the process's command-line arguments and environment 
variables;
               for details, see execve(2).


Thanks
Anshul

Dear All,

I have lots of *.ts files to convert to mp4. No Problem so far, but it's a recording from a television channel with different aspect ratio. So for example the movie is 4/3 while the adverts are 16/9.

Here comes the problem: all ts files already have squished the parts with 16/9 to 4/3 (the recording doesn't care, it just records one full hour).

Is there any possibility to fix the padding to have 4/3 as 4/3 and 16/9 as 16/9 although it's in ONE file?

Atm I use this to encode my files:

/usr/local/bin/ffmpeg -y -i "$f" -crf 30 -vf "yadif, scale=iw*sar:ih , pad=max(iw\,ih*(16/9)):-Ow/(16/9):(ow-iw)/2:(oh-ih)/2" -threads 24 -aspect 16:9 "${f/.ts}.mp4" >> "${f/.ts}.log" 2>&1 ;
x264

I don't think this is supported in mp4.
(I am not claiming that it would work at all with FFmpeg, 
but if you want to put the result in mp4, I suspect it is 
impossible.)

Or do I misunderstand and all you want it either 4/3 in 
the whole file or 16/9 in the whole file (that should 
be the current behaviour).

Thx for your fast answer Eugen!

Let me clarify:

The video should be 16:9 but the padding inside the file should be dynamic  ? depending on the actual ratio of the recording.

Best,

Simon

This sounds like the current FFmpeg behaviour.

Am I correct that it is just your scale filter options 
that make FFmpeg produce unexpected results?

Subject: [FFmpeg-user] Problem with ffmpeg psnr calculate filter when image
	file applied
Message-ID: <CACU_ZbxpQdZqcin6zUiebHy78tFbxiOy=fnOV+KzAqSxij+wzQ@mail.gmail.com>

Dear all,
   I would like to calculate the PSNR of two images or two videos. I found
that the new psnr filter worked well for video files which have at less two
frames, but not for one frame, or image files.

ffmpeg version is 2.0.2
generate the files to be compared
two frames video: ./ffmpeg -i test.mkv -vframes 2 -vcodec libx264 -an
frame2.mkv
one frames video: ./ffmpeg -i test.mkv -vframes 1 -vcodec libx264 -an
frame1.mkv

this one does not work:
./ffmpeg -i test.mkv -vframes 1 -vcodec rawvideo -filter:v
"movie=frame1.mkv,setpts=PTS-STARTPTS[main];[in][main]psnr=f=c.log" -f
rawvideo -y /dev/null

this one works:
./ffmpeg -i test.mkv -vframes 1 -vcodec rawvideo -filter:v
"movie=frame2.mkv,setpts=PTS-STARTPTS[main];[in][main]psnr=f=c.log" -f
rawvideo -y /dev/null

This situation can also be reproduced using image files.
I looked into the vf_psnr.c. The do_psnr is not called.

I think this might be a bug for filter process? any suggestions to fix this?

Thanks a lot.

Regards

correct! The problem is squishing/stretching depending on the first aspect ratio.

Hello Anshul,

I am using kernel 3.8, that should support changing stack limit?
Is there any kernel config option or something which I should turn on?

For a newbie to video, navigating through  FFmpeg's documentation is made
difficult by a lack of understanding of what the underlying concepts are
and how they are connected.

Does anybody know a good introduction to video encoders, containers, frame
rates, bit rates, compression schemes, and such?

Thanks in advance.

I am having similar issues. For instance encode to yuv422p10le jpeg2000 and pipe to ffplay shows chroma problems. I'm running git-master, compiled a few minutes ago with libopenjpeg. Here's a sample command to show the issue in yuv422p10le. yuv422p and yuv420p look similarly odd.

ffmpeg -f lavfi -i testsrc -pix_fmt yuv422p10le -c:v libopenjpeg -f nut - | ffplay -

Subject: [FFmpeg-user] wrong number of ref frames
Message-ID: <58655D24-242C-4F84-AD4C-5880E3C10EBC@gmail.com>

I used ffmpeg to encode a video with libx264, using High Profile @ Level 4.1.  So the reference frames should be 9.  But it?s actually using 16.  Can anyone figure out why?  The encode also displays major visual artifacts in QuickTime Player 7 (see attached screenshot), which I?m guessing might be caused by the too many ref frames.  It plays fine in VLC.

The veryslow preset causes that. Try slower preset,  I am also having same problem with QuickTime.

Thanks, using ?slower? preset fixes the glitches in QuickTime, and uses 8 ref frames, as expected.  I suppose I could manually specify 9 if I wanted to.  Is this a bug?  I thought profile and level restrictions are supposed to override all other settings.

I agree that the variable -ref values in preset did cause some grief. You could possibly modify and create your own preset as I had trouble passing --ref 4 in the command line and preset option.

I plan to append to this thread when I am back from travel as I am having artifacts show up with slower and medium presets as well with default and level 5.1 profiles.

Sorry if this is not completely clear:
The native jpeg2000 decoder is (very) highly experimental, 
it is not meant for real-world use cases, particularly 
not for testing lossless compression.

I believe, contrary to x264 cli, that -level only sets the flag and not
the number of refs.

I may be wrong and I'm feeling too lazy to check.

The FFmpeg Wiki has some articles targeted for the new user:

http://trac.ffmpeg.org/wiki/

"The H.264 Advanced Video Compression Standard" (2nd edition) may be of
interest.

These answers on superuser might help:

Of course if you have any specific questions you can ask them on this

Hi Harry,
On  x86 Linux, under the bash shell, then using
ulimit -s nnn
will change the maximum stack size, for any programs run from that shell.

You could try increasing the limit and run ffmpeg again.
Running
ulimit -s
will display the current limit.

So unless someone has some other option or advice, I think I will just 

fps=fps=30000/1001,fieldmatch,decimate,yadif (which will yadif everything.) should get rid of the combing, but it will blurr everything a bit too. U

missing "-vcodec":
Dave and I used the new syntax "-v:c".

Same here.
I've verified Dave's commandline with the video I've used for my tests
(http://media.xiph.org/video/derf/y4m/football_422_ntsc.y4m):
The chroma seems distorted and stretched.

Git HEAD built a few minutes ago with libopenjpeg-dev from the main
Ubuntu 12.04.1 repositories (1.3+dfsg-4+squeeze2build0.12.04.1).

I've ran Dave's test command with "yuv422p" and "mandelbrot":

As said, this needs --disable-decoder=jpeg2000 or 
-vcodec libopenjpeg.

If there is anything unclear in my last mail (except 
me preferring the old syntax), please tell me!

For me it was indeed unclear. Sorry :)
You say it needs "--disable-decoder=jpeg2000" *OR* "-vcodec libopenjpeg".

So I assumed that if I should use "-vcodec libopenjpeg" as encoding
parameter, which I thought is equivalent to "-vcodec libopenjpeg".
However, I now added "-vcodec libopenjpeg" to the decoding side of ffplay:

------------------------------------------------------------------
$ ffmpeg -f lavfi -i testsrc -pix_fmt yuv422p -vcodec libopenjpeg
-qscale:v 0 -f nut - | ffplay -vcodec libopenjpeg -
------------------------------------------------------------------

Then I figured that "--disable-decoder=jpeg2000" was a configure flag.
So I recompiled ffmpeg with this switch.
With that build I don't need to supply "-vcodec libopenjpeg" to ffplay
and Dave's commandline works correctly.

Both options indeed display the video correctly :)


Thanks, and sorry for the misunderstanding,
Pb

?Hi,

How can I get the algorithm used/the source code for changing the resolution & frame rate of a video using the FFMpeg tool. I would like to know the method used for the up/downsampling of the spatial & temporal resolution of the video.

Thank you.

Hello Anshul,

Further on this, I tried changing the stack size for user-mode programs (set it to unlimited) even then the same issue occurs
Any further pointers?

Hello Swapnil,

Thanks for the reply
I am not too versed with the essential libs or sub-programs inside the huge ffmpeg package
Can you please name a few which are really essential so that I can try disabling the rest?

Hi

Please dont top post over here, considered rude

    Please provide gdb output, seehttp://ffmpeg.org/bugreports.html

    Carl Eugen

You could try same problem in developer list, may be its problem(bug) in 
ffmpeg

make sure that you are using git version, and check for the fate status 
for ppc, from there you can get
what are the configuration people using on ppc with ffmpeg

Thanks
Anshul

Hi

as stated by Carl
You should report bug with gdb output and try same problem with ffmpeg 
developer list
It look bug in ffmpeg to me.

as stated by swapnil
you can try all the working configuration from fate for ppc

Please don't top post over here, considered rude

this might be missing a --cross-prefix, something like
--cross-prefix=/usr/powerpc-linux-gnu/bin/
and
--cpu=e500v2

if above doesnt help

gdb disassembly (and instruction pointer) would be quite helpful

I can now reproduce the problem:
It works here for avi (at least with some players) 
in the sense as it changes aspect just like the 
original transport stream does but for mov the global 
aspect "wins" and the filter chain - afaict - does 
not allow to switch parameters frame-wise (which 
would be necessary for changing pad afaict).

I would like to wait for a comment from one of the 
filter experts but this will probably be an enhancement 
request. (without eta...)

Thank you for the report, Carl Eugen

I need to set up an ffmpeg command string that will allow me to take a
single input file (contains video and audio) and output it to 2 different
mp4 files at different resolutions and bitrates. There is a filter process
that needs to take place right before the encode process to deinterlace and
crop the edges of the video. I am using the -filter_complex option so that
the process only has to deinterlace and crop once and feed that out to the 2
encoders through the split filter. This all works great except that the [a]
and [b] split outputs only contain video and no audio coming out of
-filter_complex. How can I get the audio from the input file mapped into [a]
and [b] or to feed into each of the encoders? 



ffmpeg.exe -i MyVideo.mov -filter_complex "[0]
yadif,crop=in_w-2*58:in_h-2*32,split=2 [a][b]" -map "[a]" -s 640x360

Are you able to reproduce the problem with latest git (2.0.2 is a bit
old and we had some fixes which may be relevant).

Also you could file a bug report.

Spatial resampling: this is done in the libswscale library.

Temporal resampling: we simply drop/duplicate frames, you may have a
look at the fps filter in libavfilter.

Subject: [FFmpeg-user] ffserver HTTP stream playback freeze
Message-ID: <20131218184927.GN3396@barisone>

Hi,

I'm trying to debug this but since it's starting to take much time I
wonder if someone already got the same issue, and found a fix for it.

Scenario: I'm generating a stream with ffmpeg, which is then sent to
ffserver and published as an HTTP resource.

Problem: at some point the published stream is interrupted, I usually
get decoding errors on the client (probably due to a segmented
packet), and the player freezes. If I now restart the player, the
stream will be played again until the next freeze. Many instances of
player/downloader can be created at the same time, and each one seems
to freeze independently from the others.

The freezeing time usually is just a few seconds, but the playback
duration varies from a few seconds to dozens of seconds.

If I use ffplay or vlc the stream usually freezes after few seconds,
but playback seems to last much more if I download the stream with
wget instead (so it may be somehow related to the TCP/HTTP session
between ffplay and ffserver).

I tried several combinations, changing output container, video codec,
and bitrate, but it doesn't seem to affect the issue.

Curiously, I get this problem only when I play the stream from a
remote machine.

Here are some basic instructions to reproduce the issue:

ffserver.conf file:
---------------8<------------------------------------------------
Port 8090
BindAddress 0.0.0.0
MaxHTTPConnections 2000
MaxClients 1000
MaxBandwidth 60000
CustomLog -

<Feed testsrc.ffm>
File /tmp/testsrc.ffm
FileMaxSize 200K
ACL allow 127.0.0.1
ACL allow localhost
</Feed>

<Stream testsrc>
Feed testsrc.ffm
Format flv
VideoCodec flv
NoAudio
</Stream>

<Stream status.html>
Format status
</Stream>
---------------8<------------------------------------------------

To generate the testing stream:
ffserver -f ffserver.test.conf &
ffmpeg -override_ffserver -re -f lavfi -i testsrc -pix_fmt yuv420p -s vga -codec:v flv -b:v 500k http://localhost:8090/testsrc.ffm -nostats

Then on a remote machine:
ffplay http://$FFSERVER_IP:8090/testsrc
wget http://$FFSERVER_IP:8090/testsrc

The same issue can be observed checking the
http://$FFSERVER_IP:8090/status.html page, when the strean freezes the
transferred bytes count stops.

...

Reports of such or similar issues, suggestions or debugging hints are
very welcome.

I would surely like to get a sample. I shouldn?t need more than 20-30
seconds to see what results I?m able to produce. You might be able to
email me such an excerpt. I don?t see how any conversion to deinterlaced
30 fps would result in optimal output. Nearly any smooth horizontal
panning is like getting slapped in the face 6 times per second. If output
is deinterlaced, all 4th and 5th frames are duplicates. If not
deinterlaced, those frames are interlaced complements which still take
twice as long as a normal frame to play. Thanks.

I need to set up an ffmpeg command string that will allow me to take a
single input file (contains video and audio) and output it to 2 different
mp4 files at different resolutions and bitrates. There is a filter process
that needs to take place right before the encode process to deinterlace and
crop the edges of the video. I am using the -filter_complex option so that
the process only has to deinterlace and crop once and feed that out to the 2
encoders through the split filter. This all works great except that the [a]
and [b] split outputs only contain video and no audio coming out of
-filter_complex. How can I get the audio from the input file mapped into [a]
and [b] or to feed into each of the encoders? 



ffmpeg.exe -i MyVideo.mov -filter_complex "[0]
yadif,crop=in_w-2*58:in_h-2*32,split=2 [a][b]" -map "[a]" -s 640x360
-pix_fmt yuv420p -vcodec libx264 -preset medium -crf 18 -maxrate 700k
-bufsize 2100k -movflags +faststart -acodec libvo_aacenc -b:a 128k

Thanks Phil, I was wondering what I did wrong.

Looks like I figured it out, I was missing an additional -map option to map
the audio stream after sending the video though the filters. Works great
now.

I will see about sending you a snippet offline. I can't seem to edit the file as a vob without starting at the beginning and there aren't really good problems at that point.? So I've remuxed it into a mkv using mkvmerge.

Also, I don't think you are quite understanding the filters. fps=30000/1001 is actually just relabeling things. If you've been following the thread, the video file actually has this man frames, but the container things is has 60000/1001 fps. So that first filter just labels the file correctly. The second filter should replace the 30 fps telecined with? ABCDD non-telecinded originals. Decimate will then remove every fifth frame. At least that is how it is supposed to work. However, it doesn't always work, some frames sometimes are missed, sometimes due to editing after telecining for instance. These frames are supposed to me marked as interlaced by fieldmatch and then yadif can de-comb them, which isn't ideal, but the information to do the ideal thing is on the cutting room floor presumably. 

However, yadif=deint=interlaced isn't noticing any interlaced frames. So if I want to remove the combing, I have to yadif everything. 

In any case, I'll send you the file and you can play with it.

Hi Stefano, 

Thank you for the reply. I'm clear about the temporal scaling. Could you briefly explain the algorithm for spatial up/downsampling used in this program.

Thank you,
Syaz.

I have not seen the source code about the implementation of PSNR calculation
but as far as I knew psnr is calculated by comaring original(no noise) 
and  lossy compressed(noise)
image, I dont get why you are trying to calculate psnr of one frame

Subject: [FFmpeg-user] Good royalty free codec to encode H.264 video with.
Message-ID: <CAK18DJWK8ajJvAW=PjFKYzAzuae=GpV8OY41a6xMe2YLpqauRw@mail.gmail.com>

Hello,

*Note:* I'm not experienced in the matter of video programming or
processing. If you see some ridiculous mistakes, please be patient and feel
free to correct me.

I have some videos encoded with a H.264 codec. They are of a very good
quality. (A file of 1 hour has 2-3 GB.) I would need to convert those files
(about 200) to a format encoded with a royalty free codec. I tried to
convert them using MJPEG codec, but when I try to preserve best quality,
the resulted files are huge: about 50 GB. I used something like.

ffmpeg -c:v h264 -i /path/to/file.avi -map 0:0 -c:v mjpeg -r 30 -qmin 1
-qmax 1 -an -vf hfpli /new/path/to/resulted/file.avi

*N.B.:* I put the whole command for having a clear idea of what I'm talking
about.

Trying to increase the -qmax to 8, I still get a huge file, but more
reasonably (~10-15 GB). The problem is that increasing -qmax, some quality
issues are visible.

I tried to do the same thing, but using a different encoder, namely
libvpx-vp9. The resulted file is at a size comparable with H.264, but there
are 2 issues: the quality is clearly lower than the original file and the
conversion time is effectively enormous. Here is the command that I used:

ffmpeg -c:v h264 -i /path/to/file.avi -map 0:0 -c:v libvpx-vp9 -qmin 0
-qmax 5 -crf 2 -b:v 1M -an -vf hflip -threads 4 /new/path/to/file.webm

*Question:*
Can anybody suggest me a royalty free encoder that I could use for my
needs? I would need to be able also to encode with it video files in a
relatively good time. Can you give me some hints on this?

I'm aware that currently H.264 is the best standard regarding
compression-quality in my scenario (I don't want to create a debate right
now on that topic). I would need an encoder that would be able to get the
same video quality at a reasonable size - let's say what's over 10GB at a
file of 1 hour is too much. I also tried to encode with libtheora, but the
conversion time is huge (similar to vp9).

What is hfpli?

Mostly unrelated:
Remove "-c:v h264", it makes no sense (in most command lines), 
old documentation always suggested a minimal quantiser of "2" 
(instead of "1"), iirc that significantly reduces the filesize.

But you didn't think of providing the console output which 
is usually needed if you need support here ;-(

This should not happen: If you accept a sufficiently 
high bitrate (which is much closer to h264 than mjpeg), 
you should get perfect quality with both vp8 and vp9 
(vp8 should be faster).

Concerning your original question, consider using 
mpeg1video but if vp8 is acceptable, it should be 
able to produce significantly smaller files for a 
given quality.

have you tried the good old mpeg4 (-c:v)? I find it is in many cases a
reliable, fast workhorse and it is playable almost anywhere.

I am not a lawyer but regarding royalty-free I am not 100% sure if you
don't have to pay something to MPEG-LA depending on your use case. If
you want to be 100% sure, you should read their terms.

Just a typo. "hflip" was the intended command. Anyway, I think this does
not affect to much the quality or the conversion speed.

Here is what I tried now, with suggested improvements:

Is there something wrong with the bitrate? I can see the output bitrate is
bigger, but I think that should be a plus regarding the quality. Anyway, it
still has a significant space until it comes to the specified limit (-b:v
1M). But as you can still, the processing speed is still relatively slow
(2.0 fps if I know to interpret correctly the output).

this was meant to read (-c:v mpeg4), of course.

I don't know anything about vp8 usage but this 
looks broken. (iiuc!)
Either specify a bitrate OR a constant quality. I suspect 
that if you actually want a bitrate, two-pass encoding 
will make sense.

Unrelated:
If --disable-yasm or --disable-mipsfpu were needed, this would 
be a bug that you should report here (just remove them), I 
wonder if "--disable-asm" is a good idea: Is it really needed?

Why is "--extra-cflags=-mno-altivec" needed?

I also like asp but I think it does not count as "royalty-free", 
see the webrtc mailing list for a current (exhaustive) 
discussion.

	extensions
Message-ID: <c1282702.1cefca1.66d901.4823@simulation-systems.co.uk>

I?m trying to use the mpdecimate filter to chop out a series of duplicated frames in some media, but ffmpeg segfaults on the second frame passed through the filter.
 
The segfault does not occur if I compile with --disable-mmx, but still occurs with --disable-ssse3. Full console log and GDB trace of the segfault below.
 
The source media is available here: http://edward.torbett.co.uk/combined.mp4.
 
I?m building and running on the same machine, so no cross-compilation issues. I?m also building static executables.
 
I?ve included /proc/cpuinfo at the end for reference.
 
Any suggestions?
 
Regards,
Ed Torbett

I cannot reproduce your crash, valgrind does not report 
anything suspicious.
Could you confirm the md5sum of 
56f371bc6e11583275d76288dc0ad9c7 for your file?

This is at least unusual, is the crash reproducible with:
$ ffmpeg -i combined.mp4 -vf mpdecimate -f null -
or
$ ffmpeg -i combined.mp4 -vf mpdecimate -vcodec mpeg4 out.avi
or does a shorter configure line help?
$ ./configure --enable-gpl --enable-libx264 && make

This indicates a compilation problem (or a problem with 
sscanf), did you run make fate on your target?

I suspect you can just omit -r 25 but as said it imo 
indicates that something is very wrong.

Here's relevant output of valgrind for me: 
vex x86->IR: unhandled instruction bytes: 0xF3 0xF 0xBC 0xF6
==9526== valgrind: Unrecognised instruction at address 0x8a4728e.
==9526== Your program just tried to execute an instruction that Valgrind
==9526== did not recognise.  There are two possible reasons for this.
==9526== 1. Your program has a bug and erroneously jumped to a non-code
==9526==    location.  If you are running Memcheck and you just saw a
==9526==    warning about a bad jump, it's probably your program's fault.
==9526== 2. The instruction is legitimate but Valgrind doesn't handle it,
==9526==    i.e. it's Valgrind's fault.  If you think this is the case or
==9526==    you are not sure, please let us know and we'll try to fix it.
==9526== Either way, Valgrind will now raise a SIGILL signal which will
==9526== probably kill your program.
==9526== 
==9526== Process terminating with default action of signal 4 (SIGILL)
==9526==  Illegal opcode at address 0x8A4728E
==9526==    at 0x8A4728E: ??? (in /ldisk/ffmpeg/ffmpeg_sources/ffmpeg/ffmpeg_g)

I just ran make fate but it gave errors (as expectedly I suppose, since I cross-compiled ffmpeg from x86 machine for ppc)
Please correct if my understanding is wrong

Omitting -r 25 gives me the following

Then please concentrate on this command line and

I suspect this is a compiler problem, can you easily 
test another version?

You can run fate remote, I believe there is documentation 
on the homepage.

This looks like the same problem.
Consider adding printf's to av_parse_ratio() (which I suspect is 
responsible) in libavutil/parseutils.c.

On other machines, a windows zeranoe build from 8th December works without crash and the build I used originally (with the 'unusual' configure) works when compiled and run on another architecture (8-core Xeon server, which is the target architecture).

I don't think I can get another version on my PC without compiling it myself, which of course defeats the point of seeing if it's my compiler or my machine. I'm running CentOS 5.7 32bit.

FFmpeg does not support 16 bit gray colourspace with 
transparency information (AV_PIX_FMT_GRAY16A), this 
is ticket #644.

This sounds as if you only tested 64bit on other systems, 
or do I misunderstand?
You can test --enable-memalign-hack which should not be 
necessary on any sane system iirc.

If the crash happens always for the same frame, it is 
probably not hardware-depending.

> I'm running CentOS 5.7 32bit.

Tested now on 32bit, does not crash here.

The zeranoe build is also 32-bit.

Still segfaults with --enable-memalign-hack --enable-gpl.


We've found a CentOS RPM of ffmpeg 2.0.2 from ATrpms.net, this also segfaults at the same place when run on the same file on a different PC (but same OS/architecture):

Segfault doesn't happen with --disable-sse2.

This puts the segfault firmly in the SSE2 section of dsputilenc_mmx.c.

Assembler is voodoo to me so I'm going to have to leave this for someone else to decode. Should I file this as a bug?

Subject: [FFmpeg-user] BUG in use of extradata and extradata_size with dvb
	subtitles and teletext
Message-ID: <1387461717.7119.YahooMailNeo@web87805.mail.ir2.yahoo.com>

Im trying to work though the problems we have in converting teletext/dvbsubs to the various systems,

1. dvbsubs hard coded (overlayed) OK
Need to use -canvas_size 720x576 and scale the canvas to fit your screen, still outstanding is a way of getting the real video size to make the rescale code easier to use. 

2. dvbsubs reencoded FAILS

Command Line
ffmpeg -i ../testStreams/bbc.ts -c:v libx264 -b:v 1300k -c:s dvbsub -y -f mpegts a_dvb_enc.ts

Fails due to the fact that mpegts decodes the TS stream and sets extradata to X and extradata_size to 4, this is correct, but when it gets to mpegtsenc this information has been lost and my new code which now adds the correct header for Teletext, sees the extradata_size==0 as meaning the subtitles are Teletext and NOT dvbsubs.

So we are losing the extradata, extradata_size on the re-encode, see the lines "AVMEDIA_TYPE_SUBTITLE" , this is my debug code showing the value of codec->extradata and codec->extradata_size at this point in my ~ mpegtsenc.c:374 code

??????? case AVMEDIA_TYPE_SUBTITLE:
??? av_log( NULL, AV_LOG_WARNING, "AVMEDIA_TYPE_SUBTITLE %p %d\n", st->codec->extradata, st->codec->extradata_size);
??????????? if (!st->codec->extradata_size) {

As you see I try and differentiate between the two types using the fact that the teletext does NOT use extradata and extradata_size.

This runs though the encode cycle but i have yet to find anything, vlc/ffplay/etc that will show the subtitles. Get "invalid subtitle stream id" in vlc

Any ideas on the problem in number 2?

I get onto number 3 when i have number 2 fixed.

How is this teletext-related?

(Completely unrelated: Don't you agree that it makes 
reproducing all kind of bug reports much, much harder 
if you use "-c:v libx264"?)

This looks like ticket #2024

I think Carl suggested this, but any chance of trying with a more up
to date toolchain? gcc 4.1 is not exactly the most up to date
compiler, almost certainly if there is a bug, it is a bug in gcc that
will have been fixed in a later version of gcc.

I have no knowledge of CentOS 5.7, but it appears there is a
contributed devtools package for CentOS 5 that would give you a modern
toolchain (gcc 4.7, modern binutils, modern gdb, modern valgrind) that
installs to /opt.

http://people.centos.org/~tru/devtools-1.1/readme

Cheers

Did you read my explanation why it fails, it fails becase MPEGTSENC.C 
thinks this subtitle is TELETEXT not DVBSUBS, so its related as it 
affects bot DVBSUBS and TELETEXT

Sorry from now on i will omit the libx264, but as always the normal 1st reply is "COMMAND LINE AND OUTPUT OR WE WONT TALK TO YOU", now i post my 
command line what do i get ...

I cant win can I


Also the video encoder makes no difference as its the subtitles im talking about

Don't you think you should look at the the remuxing problem (3) instead of
the encoding first, since you need a correct demuxing/muxing for testing
this?

Anyway, for the record, details on these problems can be found in #2024
and #2989 at least. Thanks for your last comment in #2024 BTW.

So far we have only one working case: dvDsub ? dvBsub transcoding. dvBsub
to dvBsub is broken in both transcoding (but potentially related to a
demuxing issue) and transmuxing.

Thanks for the 0:30 sample file. Yes, some are interlaced, but not in the
pattern I would expect for telecined video. If you open it in mplayer, you
can pause it at any point by pressing space, then advance frame by frame
using ?.?. What I see for the interlacing is the pattern of 3 frames
interlaced followed by 3 frames non-interlaced. Please try that and let me
know if you agree. Pulldown would be interlaced frames 4 and 5 of every 5,
I believe. Here?s a yadif filter chain that did the same thing as the one
I mailed you privately using -deinterlace, except probably better. Thanks
again.

ffmpeg -i test1.mkv -pix_fmt yuv420p -c:v libx264 -vf
?yadif=0,fps=fps=30000/1001" -preset slower -crf 18 -x264opts

Remuxing problems go away as soon as you remove the hack in ffmpeg.c for doing the dual packet!, what is needed in ffmpeg.c is a heartbeat which takes the last updated subtitle, adds on the timeout and waits for this to pass before issuing a "0 object region". im looking into the code for the "subs overlay" hack at the moment. What will happen now is the last subtitle will stay on sreen until a new one arrives.

With all the hacks its hard working out what to look at

No i dont think #2024 is what im looking at, this is new. DVBSUBS are decoded and the 4 bytes for the page ids are correctly remembered but crucially when the output stream is created as a dvbsubs stream the extradata and extradata_size are not updated, so these are NULL and 0.

Now my modification to show the teletext page information, and also the code which puts these back into the new TS are dependant on the extradata size being 0, so any transcoded dvbsubs are flagged in the pmt as as teletext.

Only working ones are

dvbsubs decoded and overlayed
teletext decoded and overlayed

Isn't the dual packet hack only called with transcoding?

Also, we should move this discussion to ffmpeg-devel.

Well, it was a pain to install but I'm happy to report that it's resolved the segfault. Looks like something in the toolchain was screwing it up.

Thanks for the help on this one Carl and Tom!

I believe the link gives a lot of informations about the 
algorithms (and very little about the usage) - that's why 
I posted it.
For information about the used mathematics it will be 
necessary to read the fine source afaict.

Works fine in my internal network and in an external one, freeze
issues observed in two external networks. TCP debugging with wireshark
shows that the freeze occurrs just after a TCP ZeroWindow event on the
client side, then for some reasons the server stops to react and won't
send new packets.

At this point, the issue seems probably due to the network
configuration and is maybe related to the buffering parameters adopted
by client / server. Suggestions about how to handle the issue are
still welcome.

Subject: [FFmpeg-user] Map Only Certain Channels to EBUR128 Filter
Message-ID: <52B3BDF6.5030209@knhn.me>

Hello,

Thanks in advance for any replies.  I frequently deal with clips that 
have a 5.1 mix on channels 0-6 and the stereo mix on 7-8.  How could I 
pass just the 5.1 or stereo mix channels to the EBUR128 filter?

Below is my attempt using a filter chain of channelmap and ebur.  I must 
not understand how to use a chain of filters.

ffmpeg -i foo.wav -filter 'channelmap=0|1|2|3|4|5:channel_layout=5.1;

I guess this is one advantage of using "-vcodec" instead since it's
harder to typo/transpose.

You mean: the client sends ZeroWindow to the server and the server stops
reacting? At a wild guess, I would say that ZeroWindow will cause a system
call to block on the server instead of succeeding immediately, and that
could be handled wrong in ffserver code: the socket could be in non-blocking
mode, the system call returns EAGAIN, and ffserver treats it partially as a
permanent error.

Message-ID: <3B24A2928FED1E42A394BF9E6099788B04C0507A75@NLHFD-MSG008.domain1.intra>

Hi All



I need to do the following:



1.       Decode a H264 stream and identify a certain B frame/picture

2.       Perform some modifications to the frame

3.       Re-encode _only_ that frame and insert back into the original stream, without any modifications to the surrounding frames. I do not want to re-encode the entire stream



So if the input GOP is IBBPBBPBBP..., the output GOP must be IBBPB'PBBP...



Does the ffmpeg/libav API allow the encoder context to be initialized from the decoder context such that this can be done, and if so, can anybody provide me with some ideas or examples?



Thanks

Roelof

Please do not cross-post, this is (always) considered rude.

The FFmpeg API certainly allows you to extract NAL's from H264 
streams (and it obviously allows to write them in an output 
stream) but I wouldn't be surprised if you have to make 
major changes to libx264 to allow inserting a frame into an 
existing unchanged stream.
Note that B-frames are allowed to be reference frames, for 
such cases what you want is impossible afaict.

This is a little old, it should work fine with current FFmpeg 
git head.

I don't think so, the issue cannot be reproduced systematically, I got
the freeze only in particular networks (2 over 3 tested), and never on
my local network. So it seems it is somehow related to the tested
network (and seems more a problem at the network level rather than at
the application level, where I can't see apparent errors).

The ZeroWindow event usually triggers the condition where after some
short time I see no packets from the server, nor the connection is
closed, so that no data is fed to the client and it seems to hang.

Remember that the alternative is to add the following

I double checked, and it did have the 3-3 pattern you suggested. I don't know what could cause that. I looked around on the internet and couldn't find a Telecine process that would produce a 3-3 pattern. I decided to just do yadif. In this case the fps filter is unneeded. The resulting file thinks it has a different fps but it plays correctly. I use yadif=deint=interlaced and it worked fine.

Thanks for your help.

Yes, I tried this.  It would not play the video.  The error message was:
    Cannot find codec matching selected -vo and video format 0x48564646
This occured even when I played AVI files that previously worked.
So, I removed that line from the MPlayer config files.

Please paste your complete MPlayer config file.

Note that it works fine here (and that I copy-pasted the 
line from this very email to make sure that I did no 
make a typo) so I am quite sure that you did not insert 
the line correctly into your config file.

And the reason I did not write:
"
add the following line to your MPlayer config file: vc=-raw422P,
"
but
"
add the following line to your MPlayer config file:
vc=-raw422P,
"
was of course to make it as clear as possible imo how 
the line you have to add to your MPlayer config file 
looks like.

Subject: [FFmpeg-user] CD-DTS
Message-ID: <A262680D-E7BC-43CE-8E02-2050EC81542E@yahoo.fr>

Hi list,

Has anyone succeeded in making a CD-DTS (a.k.a. DTS Audio CD a.k.a. 5.1 Music Disc) ?
I'm desperately trying to find the right combination of options to create a valid, burnable wave file that spits DTS on my receiver.
Unfortunately, all I get is white noise.

The key seems to pack a DTS flow inside a classic 2-channel, 44100Hz, PCM-declared WAV container.

Unfortunately, 
$ ./ffmpeg -i input.aac -acodec dts -strict -2 -ar 44100 dts-output.wav
creates a 6-channel wav container for the DTS datas and
$ ./ffmpeg -i input.aac -acodec dts -strict -2 -ar 44100 -ac 2 dts-2c-output.wav
downmix the 5.1 aac input to a 2-channel wav file

I tried to bit-bang the dts-output.wav so the wav container is declared as wanted but it fails.
The file at http://www.lamoateffe.com/samples/RedHouseDTS.wav is a valid wav-packed DTS file.

Any advice welcomed.
Thanks,
Ionel

About this, it is probably true (that is: we may extend synopsis
section to give a brief explanation). Note that in case of ffmpeg this
is introduced in the first section "Introduction".

There are tons of examples in the various sections. Also there is the
wiki and many third-party (more or less outdated) tutorials you can
find on the Internet.

This is partly introduced in "Detailed description":
https://ffmpeg.org/ffmpeg.html#Detailed-description

About terms, this is really out of scope of FFmpeg, since it employs
the standard terminology adopted in the multimedia field, and the user
is supposed to have some basic working knowledge and terminlogoy about
the main topics (encoding, decoding, muxing, demuxing, etc.).

That said, having some sort of FFmpeg dictionary (ffmpeg-jargon(1)?)
would be probably a good idea.

Even for this very basic tool, I can't really understand what it's
doing by simply reading that page, without having more contextual
information.

...

This is not to say that FFmpeg documentation is complete or cannot be
improved, far from it, just that your claim is a bit exagerated.

I don't intend to respond pointwise Stefano's objections to my criticism of ffmpeg's documentation as it would clog the list with largely pointless back-and-forth which is unlikely to have a useful result. I am aware that user opinion of ffmpeg and its documentation is not valued and I'm not going to waste my time; my initial objections stand.

The experimental dts encoder is unable to reach 
a given bitrate so this cannot work.

I didn't test the following and I am not claiming 
it works but if you have a dts-encoded file with 
the correct bitrate (!), the following is the 
approximate process:
$ ffmpeg -f s16le -ac 2 -ar 44100 -i your_dts_encoded_file.dca
-acodec copy out.wav

This is not an ffmpeg problem (if I'd been more thorough I'd have seen that).   It is a bug in libvpx - noted here:

Otoh, the following may work in theory:
$ ffmpeg -i input.aac -strict -2 out.dts
$ ffmpeg -f s16le -ac 2 -i out.dts -acodec copy out.wav

(44100 is the default rate)
In my test the bitrate was correct to my surprise (1411 kb), 
I believe it was completely off in the past.

This works with ffplay, testing with a hardware decoder is 
very welcome!

I'm using a daily build version : 
./ffmpeg -version
ffmpeg version N-59266-gd1b8e01
built on Dec 21 2013 13:21:23 with Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)

libswscale      2.  5.101 /  2.  5.101
libswresample   0. 17.104 /  0. 17.104

I gave the rcaenc encoder a try : byte ordering is different, content is different but headers look the same.

I created a dca file with dcaenc using the folowing sequence : 
$ ./ffmpeg -i input.aac -acodec pcm_s16le -ar 44100 test.pcm.44100.wav
$ ./dcaenc test.pcm.44100.wav test.dcaenc.dts 1411200

The ffmpeg dca file was created like this :
$ ./ffmpeg -i input.aac -acodec dts -ar 44100 -strict -2  test.dts.44100.dts

Here are the tests results :
- plain dcaenc file burned with cdrecord '-audio -pad -swab' => DTS is OK on receiver, music plays, file cannot be read on VLC
- plain ffmpeg dts file burned with cdrecord '-audio -pad' => DTS is OK on receiver, SILENCE plays, file cannot be read on VLC
- dcaenc file, packed in a wav file with Carl's command and burned with cdrecord '-audio -pad' (no -swab here) => DTS is OK on receiver, music plays, file cannot be read on VLC
- ffmpeg dts, packed in a wav file with Carl's command and burned with cdrecord '-audio -pad' => no DTS, noise on receiver, file cannot be read on VLC

Works fine here for a random dts input file...

As said, this is not completely surprising given that 
our encoder is highly experimental;-(
Does the resulting wav file play with ffplay?

ffplay does not build as I don't have the SDL compiled ?

The alternative is:
$ ffmpeg -i out.wav out2.wav
(and play out2.wav with any media player)

You are right.
Given the following sequence :

$ ./ffmpeg -i input.aac -acodec dts -strict -2 -ar 44100 output.dts.44100.dts
$ ./ffmpeg -f s16le -ac 2 -ar 44100 -i output.dts.44100.dts -acodec copy test.dts.44100.wav
$ ./ffmpeg -i test.dts.44100.wav test.unpack.wav

- output.dts.44100.dts :
-- NOT playable in VLC
-- CAN be burned as audio track with cdrecord
-- receiver detects DTS stream BUT plays silence

- test.dts.44100.wav :
-- NOT playable in VLC
-- CAN be burned as audio track with cdrecord
-- receiver DOES NOT detect DTS and plays noise
-- shntool sees a valid wav file of the correct duration

- test.unpack.wav :
-- IS playable in VLC, seen as PCM S16 LE, 44.1kHz, 16b, with 5.1 channels
-- CANNOT be burned as audio track in cdrecord ("inappropriate audio coding")
-- shntool sees the RIFF magic bytes BUT detects an unsupported audio format (0xfffe).


A working workflow to create a multi-channel cd is then :
- extract multi-channel source to a multi-channel wav file
$ ffmpeg -i multichannel.input.file -acodec pcm_s16le -ar 44100 multichannel.pcm.wav

- use dcaenc to encode it to a dca file
$ dcaenc multichannel.pcm.wav dcaenc.dts 1411200

- pack the dca file inside a stereo wav container
$ ffmpeg -f s16le -ac 2 -ar 44100 -i dcaenc.dts -acodec copy final.wav

- burn it
$ cdrecord -audio -pad final.wav

This is unrelated to your original question, it simply means 
that these application do not follow the Microsoft 
specification on how to write multi-channel audio in wav.
(This is the same problem as "Remuxing multi-channel ac3 in 
avi doesn't work" which is reported quite often.)

You could try your original task with stereo (or mono) 
input just to make sure that the problem isn't that the 
FFmpeg dts encoder works badly with multi-channel input.

With a stereo input, all resulting files are burnable :
- the pure dca file is recognised as a dts stream by the receiver and instead of silence (as with the multiple track input), it plays a choppy version of the music, very quietly, mixed with a white noise ?
- the first wav-pack file plays noise, not detected as dts
- the repacked file is played as a classic stereo track, with no dca detection

Message-ID: <CAH8ereiXkT2WW7M2DN34tQmfA0xHWL5Ek-Gh2ydsXd7Vg2pQVQ@mail.gmail.com>

This is my scenery: I have a small spy camera and use a DVR to save the
video. It create a file every 60 minutes.

Now I want to join this videos with the same quality from it original.

I am doing a experiment: I want to show the exactly quality from this
camera. I read a tutorial like
this<https://trac.ffmpeg.org/wiki/How%20to%20concatenate%20(join,%20merge)%20media%20files>
but
I am not sure if I did a good job. I open the result video and it look like
to have problem with index, because it is a little weird when I play the
video with a video player. It is difficult go to a time or just go fast 10
second ahead.The original video didn't have the same problem. (I join two
video of 800MB and it create the 1600MB file).

The things I want to do is:
- Join video files
- Maybe cut some part in the start or end of the film
- Delete the audio

I can't believe I am not making it work :( What command like did you
suggest?

This is the spec of the video:

Please provide the failing FFmpeg command line together with 
the complete, uncut console output and please tell which 
player you tested.

Lol, maybe the correct question was: how to create this command line for
this video file.

But forget, I solved the problem because I found other program (AVI Tools).
I paid 7,00 to it because I don't want learn to use FFmpeg :) For what I
want it is good.

Anyway thanks for all.

You now:
1) paid for something that you can get for free (here)
2) downloaded outdated software (that is not only 
known to contain bugs but even security issues)
3) Supported copyright violators

Please do not top-post here, Carl Eugen

Subject: [FFmpeg-user] mp4 muxing and libx264 GPL licensing
Message-ID: <1387813472209-4662871.post@n4.nabble.com>

Hi,

I have written an MP4 muxer  (for H.264 elementary stream coming from a
compressed video capture card) using FFMPEG library like this:

video_codec = AV_CODEC_ID_H264;  
....
codec = avcodec_find_encoder ();
avcodec_open2();
....
loop av_write_frame(); 

The muxer works just fine.
The problem is that this processing uses libx264 encoder although I don't
need the encoding features (the video is already compressed in the capture
card)
I need to avoid using libx264 because it is not LGPL. 
Any thoughts how I can only use FFMPEG's muxing capabilities without setup
libx264 encoder?
Thanks,

I use the following terminal line:

<avconv -i ~/xxxxxxx/CIMG0228.MOV -vf transpose=1 -r 25 -vcodec libxvid
-vtag XVID -s 1920x1080 -aspect 9:16 -b 3000k -maxrate 5000k -qmin 3 -qmax 5

-async 50 -acodec libmp3lame -ab 128k -ar 44100 10.avi>

To be honest, I'm not an terminal expert, I use it because it was
recommended and it works. Is there any simple solution?

Subject: [FFmpeg-user] Full to studio levels
Message-ID: <CAMStzJc8RAv+=P9MEhbQ20zFyE9z8AjL-H=Hgge7PDA3v+ZDKA@mail.gmail.com>

Hey everyone,

I've been stuck with a level scaling problem. I'm trying to generate
broadcast compliant HD mxf files so they have to adhere to the BT.709 spec.
Meaning BT.709 primaries with a 2.4ish power function and "studio" luma
levels meaning black starts at 16 and white peaks at 235.

My sources are full scale BT.709 dpx files. And to force the output to
BT.709 primaries I have to add a colormatix filter from bt601 to bt709
strangely enough. It does work however.

The only thing I just cant seem to get working is the luma scaling. I've
tried the scale filter with the in_range and out_range options. And I've
tried the -color_range option on both the in and output files.
That does change the pix_fmt indication from yuv420p to yuv420p(tv) but it
doesn't change the picture.

I've built ffmpeg v 2.1.1 for this project.
I hope you guys can help and in time I can help out the project!

Rio

I do this with mplayer/mencoder: 

If you want to extract subtitle index N with language L from track ${TITLE} of the iso (use "lsdvd mpfc.iso -qst ${TITLE}" to see your options, the lsdvd list starts at one, you need to subtract one.) 

mplayer -dvd-device mpfc.iso dvd://${TITLE} -dumpfile dump.vob

then

mencoder -really-quiet dump.vob -nosound -ovc copy -o /dev/nul -vobsubout subs-${N} -sid ${N} -vobsuboutindex ${N} -vobsuboutid ${L}

This produces two files: subs-${N}.idx and subs-${N}.sub.

avconv is known to contain several hundred user-reported 
bugs that are not reproducible with FFmpeg, some of them 
security-relevant, please understand that we cannot 
support it here. 
See http://blog.pkh.me/p/13-the-ffmpeg-libav-situation.html 
for more information.
If the problem you see is reproducible with current FFmpeg 
from http://ffmpeg.org/download.html please post your 
command line together with the complete, uncut console 
output here.

(This is old.)

>    Stream #0:2 -> #0:0 (copy)

The srt file format only supports srt (and text and subrip) 
subtitles, you cannot mux ("copy") dvdsub into the file, just 
as you cannot put mp3 into an aac file.

>    Stream #0:2 -> #0:0 (dvdsub -> srt)

dvbsub is a bitmap subtitle format, srt is text-based but 
since FFmpeg does not contain any ocr routines, you cannot 
convert a bitmap subtitle into a text-based subtitle format.

Just curious...is this about hardened subtitles? Or also applicable in
cases where the video does not show any subs by default?

I've tried variations on the above command, including different options for

I've also tried not doing it through the scale filter but via the

And can somebody clarify why I have to put a color transform from BT.601 to
BT.709 in there to retain my primaries while my source already is BT.709?

Thanks

Well, both those lines are exactly the same. 
Anyway, I figured out that the comma
was required in the config file.  I previously thought you
added it to format your message.  If I add the comma, then
mplayer displays the file with no blue tint.

So, thank you.

Hi,

I am a total newbee in the ffmpeg and conversion area. I've tried to
search the documentation and came up with some recipees to convert my
mov movies to either avi or mp4.

But the result is always far inferior wrt quality. I don't really care
about the size, but I would like to keep the original quality as far as
possible.

Anybody has some useful recipees?

Here you cannot see the direct mapping of 0x81a950 to stream 0:1 etc.. So I 
tried to do it verbose:

Here you can find out the mapping, because the resampling filter is inserted and 
the debug message "casually" mentioned 0:1 and 81a970 in one line. There are 
streams that do not need a resampling filter. Is there a possibility to do the 
mapping anyway?

regards,

The following could work.

ffmpeg -i input.mov -q:v 3 output.mp4

The parameter q:v, set to 3 here, controls the quality of the video output.
Quality goes down as q:v goes up.

Good luck,

Gustavo J. Mata

Tried it, but it does fail:

Subject: [FFmpeg-user] Bitstream "h264_mp4toannexb" filter does not work
Message-ID: <CAOJzLopVY5sM6yq1gMXwMrK1DjLDe5bw=PPOJLQ0dn5S-yKofg@mail.gmail.com>

Hi all,
We are using FFmpeg libraries git-ee94362 libavformat v55.2.100. Our
purpose is to mux two streams (video and audio) into M3U8 playlist using
HLS.
We are using AV_CODEC_ID_H264 output encoder, AV_PIX_FMT_YUV420P output
video pixel format and CODEC_FLAG_GLOBAL_HEADER flag for the encoder.
The last causes us to use "h264_mp4toannexb" bit stream filter.
So, here is the code snippet:

AVPacket outpkt = {0};
int isGotVideoPacket = 0;

av_init_packet(&outpkt);

// convert time in stream time base units, so that the encoder will fill
the packet appropriately
out_video_frame->pts = (int64_t) (video_frame_count *
in_video_frame_duration / av_q2d(out_video_stream->time_base));

int ret = avcodec_encode_video2(enc_out_video_ctx, &outpkt,
out_video_frame[i], &isGotVideoPacket);

assert(0 <= ret);

// if size is zero, it means the image was buffered
if ((1 == isGotVideoPacket) && (0 < outpkt.size)) {

 AVPacket new_outpkt = outpkt;

 if ((AVBitStreamFilterContext*) 0 != vbsf_ctx) {
  AVPacket new_outpkt = outpkt;

  ret = av_bitstream_filter_filter(vbsf_ctx, enc_out_video_ctx, (const
char*)0,
   &new_outpkt.data, &new_outpkt.size, outpkt.data, outpkt.size,
   outpkt.flags & AV_PKT_FLAG_KEY);

  if (ret > 0)
  {
   outpkt = new_outpkt;
  }
  else
  {
   // We get ret = -22
   char errbuf[128] = "";

                        // Both the functions get "Error number -22
occurred" that don't explain anything
    av_strerror (ret, errbuf, 128);
   av_make_error_string (errbuf, 128, ret);

  }

  assert(0 <= ret);

 }

 outpkt->stream_index = output_video_stream->index;

 // If to comment av_bitstream_filter_filter() and "if-else", then
 // At frame #37 we get the following error from
av_interleaved_write_frame():
 // [mpegts @ 09628140] H.264 bitstream malformed, no startcode found, use
the h264_mp4toannexb bitstream filter (-bsf h264_mp4toannexb).
 ret = av_interleaved_write_frame(ofmt_ctx, &outpkt);

 assert(0 <= ret);
}


Our questions:
1. What is the meaning of the "-22" error from av_bitstream_filter_filter()?
2. Where can we get full FFMPEG error code description list?
3. If we are using av_bitstream_filter_filter() right? If no, what is the
right way?

(Why do you want to "convert" from mov to mp4, they are mostly 
the same?)

Command line and complete, uncut console output missing.

Use -qscale 2

If you actually don't want to "convert" but just remux, 
-vcodec copy is the alternative.

libx264 should not be used for remuxing h264 (and I 
believe FFmpeg cannot use it).

This is too old.

As said, why do want to change "mov" to "mp4"?

You can remux this stream with -vcodec copy

PCM audio is only supported in mov, not in mp4 (this has 
nothing to do with FFmpeg, the limitation is inthe mp4 
specification), you have to convert to a supported audio 
format, use for example -acodec aac -strict -2 (fdk is a 
better encoder, libvo-aac is not).

Hi Gustavo,

It does! And so does
ffmpeg -i input.mov -q:v 3 output.avi

Thanks!

Message-ID: <CANGWO+haXCwsLy30tPLrTbMkZoJ5m+JDNSuepQu00xGUcZOOOQ@mail.gmail.com>

Hello Everyone,
    I'm fairly new to the concepts of video formats. So, pls bear with me,
if the queries are too basic!! :)
    I want to convert the MPEGTS file using ffmpeg to avi format. Using
ffmpeg, I have done that without any issues.
    But I want to explore a little more into these formats. I have got some
basic doubts while going through the internet on video formats.
    Kindly take some of your time to clarify these. (I've already searched
enough using google!!)
    1. Where can I get the specification document for MPEGTS. (I've browsed
the official site of MPEG (*mpeg*.chiariglione.org/), but could not locate
it. To admit, I found the site a little confusing in the first attempt :()
    2. I used ffprobe to find the stream info of a ts file. But, can I use
FFmpeg to get the header details of a MPEGTS file? (I had earlier used one
tool, which parses the avi file, and gives the header values and
video/audio data in a good readable format. Expecting similar one for
MPEGTS format :))
    3. Finally, I see there are MPEG and MPG formats. Are these both same?
If not, what is the basic differnces between these two formats? In the
FFmpeg code, I could locate files for decoding MPEG, but not MPG. (It would
be helpful, if someone can give me the pointers towards specification docs
of these also)

   Once again, I request you to pls bear with me, if the queries are too
basic :)
   Thanks in Advance!!

Regards,
Sachin

Subject: [FFmpeg-user] Bitstream "h264_mp4toannexb" filter does not work
Message-ID: <CAOJzLoqdXhoSsXf9jjS=4Y8oXPhP-REnBwdk-PdMjMXAC5VzeA@mail.gmail.com>

Hi all,
We are using FFmpeg libraries git-ee94362 libavformat v55.2.100. Our
purpose is to mux two streams (video and audio) into M3U8 playlist using
HLS.
We are using AV_CODEC_ID_H264 output encoder, AV_PIX_FMT_YUV420P output
video pixel format and CODEC_FLAG_GLOBAL_HEADER flag for the encoder.
The last causes us to use "h264_mp4toannexb" bit stream filter.
So, here is the code snippet:

AVPacket outpkt = {0};
int isGotVideoPacket = 0;

av_init_packet(&outpkt);

// convert time in stream time base units, so that the encoder will fill
the packet appropriately
out_video_frame->pts = (int64_t) (video_frame_count *
in_video_frame_duration / av_q2d(out_video_stream->time_base));

int ret = avcodec_encode_video2(enc_out_video_ctx, &outpkt,
out_video_frame[i], &isGotVideoPacket);

assert(0 <= ret);

// if size is zero, it means the image was buffered
if ((1 == isGotVideoPacket) && (0 < outpkt.size)) {

 AVPacket new_outpkt = outpkt;

 if ((AVBitStreamFilterContext*) 0 != vbsf_ctx) {
  AVPacket new_outpkt = outpkt;

  ret = av_bitstream_filter_filter(vbsf_ctx, enc_out_video_ctx, (const
char*)0,
   &new_outpkt.data, &new_outpkt.size, outpkt.data, outpkt.size,
   outpkt.flags & AV_PKT_FLAG_KEY);

  if (ret > 0)
  {
   outpkt = new_outpkt;
  }
  else
  {
   // We get ret = -22
   char errbuf[128] = "";

                        // Both the functions get "Error number -22
occurred" that don't explain anything
    av_strerror (ret, errbuf, 128);
   av_make_error_string (errbuf, 128, ret);

  }

  assert(0 <= ret);

 }

 outpkt->stream_index = output_video_stream->index;

 // If to comment av_bitstream_filter_filter() and "if-else", then
 // At frame #37 we get the following error from
av_interleaved_write_frame():
 // [mpegts @ 09628140] H.264 bitstream malformed, no startcode found, use
the h264_mp4toannexb bitstream filter (-bsf h264_mp4toannexb).
 ret = av_interleaved_write_frame(ofmt_ctx, &outpkt);

 assert(0 <= ret);
}


Our questions:
1. What is the meaning of the "-22" error from av_bitstream_filter_filter()?
2. Where can we get full FFMPEG error code description list?
3. If we are using av_bitstream_filter_filter() right? If no, what is the
right way?

Andrey Mochenov.

AFAIK, HSL implies MPEG-TS, and MPEG-TS implies no global header. Can you
explain why you chose to use global header?

There is something seriously wrong either in your libc or your build of
ffmpeg. You are not the first one to exhibit the problem. Please help to
understand and fix it, first by explaining your exact configuration (OS and
compiler, possibly config.h at build time).

> 1. What is the meaning of the "-22" error from av_bitstream_filter_filter()?

This is OS-specific.

> 2. Where can we get full FFMPEG error code description list?

The FFmpeg-specific codes are in libavutil/error.h, installed on your
system. The latest version is browsable:

http://git.videolan.org/?p=ffmpeg.git;a=blob;f=libavutil/error.h;hb=HEAD

The OS-specific error codes are... OS-specific, and can be found in your OS
documentation.

Google for "H.222.0" but please understand that this is not an 
easy-to-read document. (I am nearly certain it will not help 
you at all if look at it.)

Maybe I misunderstand you but this is certainly not the 
"official site of MPEG".

MPEG-TS files do not have a header but ffmpeg -i yourfile 
should tell you about the audio and video in your stream.

Sorry, I don't understand this question. Consider reading 
the wikipedia article about the MPEG-2 collection of 
specifications, maybe that explains some of your questions.

Do you know the dynamics of your input frames?
Is black 0x00 and "white" 0x3FF?

Subject: [FFmpeg-user] segfault in "xv" output format
Message-ID: <20131226175335.GA27814@sunshine.barsnick.net>

Hi,
I recently discovered support for the "xv" output format, which
displays to an XVideo enabled X11 device. But running within a VNC
session, I haven't had much success. ffmpeg segfaults shortly after
opening the X11 window. For all I know, this VNC server supports
XVideo. (And even if not, no segfault should occur.)

The full report is below, with gdb analysis. ffmpeg is built from a
fresh snapshot.

Thanks,
Moritz

Subject: [FFmpeg-user] Deal with AAC priming when join file
Message-ID: <52BC974D.1070206@free.fr>

Hello,

How to deal with AAC priming when I join files ?

AAC imply priming (and padding) as describe in 
https://developer.apple.com/library/mac/technotes/tn2258/_index.html.

Normally, AAC's decoder deal with this and suppress blank sound at the 
begin and at the end of file.

How can I join several mp4/AAC file, without reencoding ?

I can't use concat because ffmpeg see only 1 input, so the primping of 
the second (and others) file isn't suppressed.


The mp4 file came from :

udp stream -> TS file

Subject: [FFmpeg-user] Transcoding with different codec (libfdk_aac) alters
	duration, how to fix?
Message-ID: <CAK_YSH_zeAOpu0KP+6ehMJYqCy5PcV2eM=hmumTESKnaoto--g@mail.gmail.com>

Hi,

I have built a transcoding workflow, which is meant to run in a distributed
Grid computing environment. The idea is to improve transcoding latencies by
first splitting input files using the segment muxer (
http://www.ffmpeg.org/ffmpeg-formats.html#segment_002c-stream_005fsegment_002c-ssegment),
then individually transcoding the segments on different nodes (into mpegts
containers) and finally join the transcoded segments with the concat
protocol (http://ffmpeg.org/ffmpeg-protocols.html#concat).

This works in principle but causes problems in the resulting output file at
the boundaries of the joined segments. Specifically, there is an audible
"gap" in the audio stream. I have created a simple test case to reproduce
the issue:

https://gist.github.com/sbalko/fcc930d4f6f5f7b03ed6

In trying to fix up this issue, I identified a possible reason. When
transcoding a segment into AAC (using libfdk_aac), the resulting audio
frames are very different. For a ~2 sec input segment, the first frame had
pkt_pts_time=*0.000000*, pkt_duration_time=*0.021333 *and the last frame
pkt_pts_time=*1.984000*, pkt_duration_time=*0.018000 *(resulting in a total
duration of 2.002 seconds). After transcoding the segment like so:

ffmpeg -y -i input_audio00.mov -f mpegts -mpegts_copyts 1 -acodec
libfdk_aac  output_audio00.ts

the output file's first and last audio frames have pkt_pts_time=*0.000000*;
pkt_duration_time=*0.021333 *and pkt_pts_time=*2.026667*;
pkt_duration_time=*0.021333,
*respectively, resulting in an overall duration of 2.048 seconds. I also
figured that the input file had 94 audio frames, whereas the output file
has 96 frames.

I realize that all this may have been introduced by re-encoding the audio
stream. In an effort to rectify the deviating timestamps, I tried the
aresample filter like:

ffmpeg -y -i input_audio00.mov -f mpegts -mpegts_copyts 1 -acodec
libfdk_aac  -af aresample=async=1000 output_audio00.ts

without any effect. I would have hoped aresample somehow retrieves the
timestamps from the input file and stretches or squeezes the output file to
match these. My understanding of how aresample would retrieve the original
timestamps is kind of limited - so perhaps something is fundamentally wrong
here (?)

Any ideas are greatly appreciated!

Thanks,
Soeren

Is there equivalent to LAME's -q switch/parameter/option (

You have the same "problem" than me : AAC protocol induced "Audio priming".
See : https://developer.apple.com/library/mac/documentation/quicktime/qtff/QTFFAppenG/QTFF

The 0.046s added in the file after AAC encoding must be a bunch of silence at the begining.

You can see my post on this list ("Deal with AAC priming when join file").

If you find a solution, thank to think to me ! :)

Message-ID: <CA+Z6vDFxJLkFug8eweuxAvc0vLvuZp+ZJSKJK=xQfgeGu=qfDw@mail.gmail.com>

Hi All,

    I am using ffmpeg in my android to play audio songs..But the problem is
that my app is consuming high cpu load almost 70%.So is there any way to
reduce cpu load of my application?

My questions:
1.If i use sdl in my android app cpu load will be reduced or not?
2.If I compile ffmpeg by enabling neon then cpu load will be reduced or not?

Thanks & Regards,
Vinay Yamusani.

Yes I'm sure. I've built some colorbars using the ARIB STD-B28 spec (
http://www.arib.or.jp/english/html/overview/doc/6-STD-B28v1_0-E1.pdf) in
linear 32bit exr and transformed it to BT.709 primaries in a dpx container.
I could send a zip with the sequence I'm using if you'd like

ScaleEngine would be my first choice in terms of price, quality and ease of configuration, assuming RTMP->HLS delivery, especially if you are a startup small business with no funding beyond your day job.

Message-ID: <CAL+AA1kAVbyaU-myn4ejgBJtBUvWLEYwkXQNM6oMQ14co762Fg@mail.gmail.com>

This is how I use FLAC:
flac --best --no-padding input.wav

Is there equivalent to FLAC's --no-padding switch/parameter/option (
https://xiph.org/flac/documentation_tools_flac.html#negative_options) in
FFMPEG?

BTW, what is equivalent value of -compression_level switch in FFMPEG to
--best (
https://xiph.org/flac/documentation_tools_flac.html#flac_options_best)
switch in FLAC?
(In FLAC --best currently synonymous with -8, or --compression-level-8, or
-l 12 -b 4096 -m -e -r 6)

What is maximum value of -compression_level switch for FLAC codec in FFMPEG?

I may misunderstand your questions but are you 
aware that FFmpeg does not use libflac for flac 
encoding (and decoding)?

So you generally cannot ask for "equivalent" 
options, I don't know what --no-padding does 
but I suspect this is the default for FFmpeg 
(and cannot be undone).

> What is maximum value of -compression_level 
> switch for FLAC codec in FFMPEG?

Maximum value is 12 for flac encoding.

As I wrote it, so unless it has been changed, ffmpeg (libavformat) will
always write 8192 bytes of padding to the header of flac files.

It should be simple(ish) to add a control for the padding.  I can do it
if people want it.  I have also considered padding for ID3 tags on mp3
files.

Subject: [FFmpeg-user] Question about splitting video with dvd_nav_packet
	data streams
Message-ID: <52BFA1E8.7030900@davidfavor.com>

I have around 100 VOB files (format @ end).

My goal is to process every stream as follows...

1) adjust volume

2) reduce bitrate

3) retain all data streams (varies 1-3 data streams/VOB file)

Questions...

Probably the easiest way to handle this is just to split all the streams into separate
files... process them... reassemble them...

1) I'm familiar with -c:v + -c:a usage... Someone let me know how to reference data streams,
    as the docs appear wrong... for example... this fails...

     ffmpeg -i VTS_01_0.VOB -c:d:0 copy -c:v:1 copy -c:a:2 copy foo.vob

     rather than a straight copy... this drops the data stream + re-encodes audio to mp2.

     So first question is just how to do a straight copy, so eventually I can do all my
     processing by substituting filters where required.

     These all fail...

     - ffmpeg -i VTS_01_0.VOB -map 0 -c:d:0 copy -map 0 -c:v:1 copy -map 0 -c:a:2 copy foo.vob

       Could not write header for output file #0 (incorrect codec parameters ?): Operation not permitted

     - ffmpeg -i VTS_01_0.VOB -map 0:0 -c copy -map 0:1 -c copy -map 0:2 -c copy foo.vob

         Stream #0:2 -> #0:2 (copy)
       Could not write header for output file #0 (incorrect codec parameters ?): Operation not permitted

2) Next question is syntax to extract each stream into a separate file + then reassemble
    all components back into a VOB container. The following extracts the first audio + first
    video stream correctly + the data stream fails because of an incorrect extension...

    So question is, what's the correct extension for extracting data streams...

    ffmpeg -y -i VTS_01_0.VOB -c:a pcm_s16le -ar 44100 -ac 2 foo.wav -map 0:1 -c:v copy foo.vob -map 0:1 -c:d copy foo.data

I know that FFMPEG doesn't use LibFLAC and has its own FLAC codec based on
source code of Flake (http://flake-enc.sourceforge.net/). But it's a pain
in the ass to find any info on Flake encoder options.

"equivalent options" = options produced equivalent (not bit-by-bit
identical streams, but have comparable compress ratio) output.

Maximum value of -compression_level option in LibFLAC is 8, maximum value
of -compression_level option in Flake and FFMPEG is 12.

Is FLAC files compressed by FFMPEG with -compression_level 12 compatible
with reference FLAC decoders and hardware implimentation?
Should I use -compression_level 8 instead of -compression_level 12 for
saving compatibility (is -compression_level 8 in FFMPEG equivalent to
-compression_level in LibFLAC in this regard)?

> It should be simple(ish) to add a control for the padding.  I can do it
if people want it.

It would be nice! Could you please add a control for the padding in FLAC
(equivalent to --no-padding swith in LibFLAC)? ;)

> I have also considered padding for ID3 tags on mp3 files.

Did you mean MP3 Header (http://gabriel.mp3-tech.org/mp3infotag.html)
instead of leading padding (silence to the beginning of each song)?
MP3 header is very useful thing. It must be enabled for VBR (VBR MP3 files
without Xing tag are unusable) and should be (very recommended) for CBR MP3
files. But I think users should still be able to control (enable/disable)
MP3 header. Could you please add a control MP3 header (equivalent to -t
swith in LAME)?

As I know, there are differences in "MP3 Header"/"Xing tag"/"INFO
Tag"/"LAME Tag" and "delay"/"padding" terms in MP3! See detailed
explanation here: http://lame.sourceforge.net/tech-FAQ.txt

Thanks for the report. I just sent a patch to the mailing-list.

Note: VNC supports the XVideo extension, but does not provide any adaptor,
at least on my setup and probably yours.

For specific options for flac you can see them by running:
ffmpeg -h encoder=flac

You can see other options for other components in a similar way.
-compression_level is a common option so it doesn't shiow under these
and then you have to guess what it might control or just read it from
the source.

If I remember using flake correctly I think that using anything greater
than 8 (the max in libflac) produces what the flac project calls
"non-subset files".  The flac project gives lots of warning about these
files.  I don't know if they actually present any problems for hardware
decoders.

12 doesn't compress much more than 8 so if you are worried about this
then stick with 8.

If you really want to know ask somewhere more dedicated than ffmpeg's
support list.  Perhaps try Hydrogenaudio.

When I said ID3 I meant ID3, specifically ID3v2 and an equivalent of
lame's --pad-id3v2-size option.

So, judging from the patch, that is the actual issue?

Yes, in my report, there's output from xvinfo saying that there are no
adaptors present:

mbarsnic at hostname:/tmp/Bui/ffmpeg/ffmpeg-2013-12-25 > xvinfo
X-Video Extension version 2.2
screen #0
 no adaptors present

Darn, I thought I had previously successfully used XVideo on VNC. I
will re-check when I'm back online at work (this was on Real VNC
Enterprise edition).

I just discovered that NoMachine NX has the same issue an said VNC
session. mplayer, with "-vo xv", kindly reports:

[VO_XV] It seems there is no Xvideo support for your video card available.
[VO_XV] Run 'xvinfo' to verify its Xv support and read
[VO_XV] DOCS/HTML/en/video.html#xv!
[VO_XV] See 'mplayer -vo help' for other (non-xv) video out drivers.
[VO_XV] Try -vo x11.

Okay, tough luck for me with the new ffmpeg "xv" output on my display
targets.

Thanks anyway!
Moritz

As you have shown convincingly, this is not correct.
Please try to apply all necessary changes in one 
command, if it fails, please post the command line

Subject: [FFmpeg-user] Pipe subtitles to ffmpeg exe
Message-ID: <462792409.1q7FETrIJ6@inpixalsta18.site>

HI, 

I am using ffmpeg to encode and mux a SPTS mpeg-ts with H264 video. I provide the input pictures thru a pipe ,and it works fine. But i need to add some DVB subtitles to the SPTS stream, and i am searching a way to provide the subtiles thru another pipe/named FIFO.

Despite mutiple trials, i am not able to generate the subtitles in this way. Note that the subtitles are generated by my own application, so i can format them in any needed format.

The command i use for the video : 
    ffmpeg -re -r 25 -f rawvideo -vcodec rawvideo -pix_fmt yuv420p -s 720x576 -i - -an -vcodec libx264 -tune zerolatency -preset veryfast -x264opts intra-refresh:keyint=12:fps=25:bitrate=1800 -f mpegts -muxrate 1800K udp://localhost:54320?pkt_size=1316

Ideally, i would like to add another input for subtitles like this : 
mkfido subtitles.fifo
ffmpeg...  -i subtitles.fifo -scodec dvbsub ....

So what could be the format of the data pushed into subtitles.fifo ?

Thanks for your help, 

Regards, SF

Message-ID: <CAK_YSH-Q1=8TasqTEjMpbXNZDvnW7Z6SNT=rQuqae5W7g20FfA@mail.gmail.com>

I figured that FFmpeg prefixes and suffixes transcoded audio streams with
"mute" intervals for other codecs too. In the same audio, I found that the
prefix/suffix lengths are libfdk_aac: 0.01024/0.01179 sec; libfaac:
0.0/0.01182 sec; mp2: 0.0044/0.00148 sec; ac3: 0.00257/0.00414 sec.

Even though the mute prefixes/suffixes are very different, this seems to be
a generic behavior, which obviously causes problems when concatenating
multiple transcoded audio streams. I wonder if there is a way to stop the
encoders from introducing these mute intervals? Will at the least look into
the libfdk_aac source.

Then please use mpeg-ts which is the only format that 
makes sense for dvbsub.
Why don't you let FFmpeg create the subtitles?

You do know that the mpeg-ts muxer (contrary to most/all 
other parts of FFmpeg) is known to have problems creating 
compliant streams?
This is particularly true for dvbsubs, this is currently 
tried to being fixed, please help if you can, see for 
example ticket #2989.

It is strange that FFMPEG don't show any warnings when user use greater
than 8 value of -compression_level switch in flac codec (if FFMPEG with
these values REALLY produces "non-subset files").

Sorry for my inattention. :-[

FFMPEG's FLAC encoder support variable block size encoding?

I've found this awesame document (

This is not generally correct for h264 streams.

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

The subject line says it all.  I'm playing an audio stream from the WWW on my Linux PC.
Can I record this stream and save it to a file with ffmpeg?

If not, what's the easiest way to do this?

Thanks

Thanks for your response.

So, if i undestand well, you recommand to create a mpeg-ts with only 1 subtitle stream in my application, then to remux it using the input pipe in the final command. Correct ?

I was not aware of the bug, i will look deeper into the code to see what is happening.

Regards, SF

I would recommend it if remuxing dvbsub would generally work.

Please explain why you cannot create dvbsubs with FFmpeg, we 
like problem reports.

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

OK, understood.

I was trying to guess how to provide the input subtitles, hence my question.

As i have now a hint, i am coding  a test to 
generate a "mpeg-ts subtitles only stream", and then try to remux it.

I will probably encounter the #2989, so i wil try to fix it, or at least understand 
what is going on


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

Oops, sorry, i missed that.

As said, this unfortunately does not work currently 
(it should though and it may be possible to fix).

You wrote:
> Note that the subtitles are generated by my own application

I am curious why you don't create the dvb subtitles with 
the FFmpeg dvbsub encoder.

Another possible source of errors would be segmentation on the server
side. I don't know how it is possible to set the maximum TCP segment
size at the OS level, tried to modify the code and use
setsocklen(... TCP_MAXSEG, ...) but doesn't seem to work
properly.

Note that at least with cvlc acting as HTTP server I don't get the
same issue, so it seems again something related to the
ffserver/network combination.

Subject: [FFmpeg-user] Capturing Video/Audio for Screen Casting
Message-ID: <1388345275.7195.YahooMailNeo@web162606.mail.bf1.yahoo.com>

Hello Everyone,

I'm running Linux Fedora 18 and I'm trying to capture both audio and video as I'm playing an mp4 file on the Linux Totem player. I could capture the video but I get no audio.? The ffmpeg command that I'm using is:

ffmpeg? -f alsa? -ac 2? -i pulse? -f x11grab
-r 30? -b:v 6000k? -acodec pcm_s16le
-vcodec huffyuv? -preset ultrafast
-threads 2? -ss 2? -t 15? outfile.avi

Does anyone have any suggestions on how I could also capture the audio?
Thanks very much for your help.

The complete ffmpeg console output about your input stream probably
wouldn't fit in the subject.

I will say "yes", but I can only guess without knowing more about your
input. Please show your command and the complete ffmpeg console output:

ffmpeg -i http://input.tld/input.stream

I don't have ffmpeg console output.  I'm playing the file
with another application (mozilla).  I want to know if I can use ffmpeg
to capture that audio and store in a file.

I want to record whatever if playing on my PC to the PC's
speakers, whether it's a stream, or whatever.  I don't have
any ffmpeg console output to show since I don't know how to
do this.

Streamripper may be more suitable for you if that is all you want to do

http://streamripper.sourceforge.net/

Bins are available on most major distros, very simple way of saving an audio stream to an MP3 file.

Very probably, although in all scientific doubt I can not rule out that
there might be another problem on your box that I did not find out.

Note that the patch has just been applied to the tree.

A plain x11 output device would probably be useful for some cases.

Untested but, if your distrib uses ALSA, maybe you could have a try with:

I have streamripper already.  It works only for ripping audio streams from the
specified URL.  It doesn't capture what is currently playing over the PC speakers.
Streamripper won't work for me because I don't have a URL for the stream I'm
trying to save to file: a javascript app plays the audio to the speakers.

The original question was whether or not ffmpeg can do this.  I'm not saying
that's it's a bug in ffmpeg if it can't.  I'm not saying that ffmpeg should do this,
if it can't.  I only want to know if ffmpeg can do this (and how).  I'm asking
here since the documentation doesn't describe this.  So, should be
easy question to answer.  Can ffmpeg do this?

Message-ID: <660463030.304674313.1388412567276.JavaMail.root@zimbra74-e12.priv.proxad.net>

Hello,

I don't understand the checksum output by ashowinfo.
Here my test : I have 2 mpegts chuncks (0.5 secs) 1.ts and 2.ts.
I look video and audio checksum at the begining of the second file, I concatene the files in 1_2.ts (with cat command) and  then look again the checksum.
Video checksum stay the same but audio checksum change in the concatened file.

Look video frame with 1E8D7B57 (stayed the same) and audio 3D1941C9 seem changed to 9F4241C9.
I write "seem changed" because the frame order change too. So I can't be sure 3D1941C9 -> 9F4241C9.

Uncut command and output below.

Regards,
Fabrice.

Yes, AAC is not the only one.

Prefix must be fixed. Suffixes is the padding of the last audio fragment, so must be variable.

I don't think it's possible, priming seems to be needed by protocol.

In my case and maybe your, I don't think the problem be priming but the fact that audio streams are a bit shorter than video.
In this case, most of "tool to concat" like MP4Box, the concat complex filter of ffmpeg, ... pad the end of audio stream to match with the video length.


For the moment, I try to play with select/aselect to give ffmpeg an audio stream a little bit longer than video (last audio frame pts+duration >last video frame pts+duration).


Regards,
Fabrice.

FFmpeg can record from alsa, oss, jack and pulse (and 
this is of course documented).
How to set up the loopback device that is (probably) 
necessary to do what you want may be out-of-scope for 
this mailing list (and I don't know how to do it) but 
I believe this was answered on mplayer-users.

Subject: [FFmpeg-user] h264 timebase question
Message-ID: <52C29ABD.9080209@stuartbruce.co.uk>

Hello

The background of the problem: I'm trying to use FFmpeg to save time 
during bulk exports of videos from Avid Media Composer. I've got a MOV 
that was exported from Avid at the right settings (h264, 640x360), which 
took some time to export. I've also got a 'same as source' export MOV, 
which exported much quicker but which is far too big. So I'm trying to 
get FFmpeg to convert the large same as source MOV so that it matches 
the settings of the correctly-sized MOV.

However, so far I haven't been able to get it to match. The problems lie 
(I think) in the time_base and codec_time_base settings.

Here's my command line so far:

-i "[source file]" -s 640x360 -pix_fmt yuv420p -vcodec libx264 -acodec 
pcm_s16be -b:v 768k -ar 44100 -profile:v main -level 3.1 
-force_key_frames expr:gte(t,n_forced) -bf 0 -ac 1 -threads 4 -y 
"[output file]"

I've pasted 3 stream analyses from FFprobe below. Number (1) is from the 
source file, number (2) is what I'm aiming for, and number (3) is what 
I'm getting.

The key differences are in codec_time_base (1/48 instead of 1/48000), 
time_base (which has become 1/12288 even though the source is 1/24000), 
and duration_ts.

Unfortunately because they don't match, this is throwing off some other 
thumbnail-generation aspects which are based on seeking to the correct 
point in the resulting movie. With the Avid-exported MOV, the thumbnail 
generation is frame accurate, but using the FFmpeg-sourced MOV, this 
seeking is often a frame off, when it absolutely needs to be frame-accurate.

Apologies that this explanation is a bit long-winded. I'm not, as you 
can tell, an encoding expert. Any help would be very much appreciated.

Thanks

Stuart

I think there is a misunderstanding here. 
In a first approach, i was thinking that it was possible to provide 
a pipe to create subtitles, with a particular picture format.
Hence my sentence, saying that my application will provide the
Subtiles.  In fact, the correct sentence would be ; 
"my application will provide the input pictures 
used to build the subtiltes".

Right now, i stopped using the ffmpeg binary solution, and i am
calling directly from my application the libavcodec/libavformat
API.

I am able to generate a MPTS with H264+subtitles, but when i 
replay it, I am facing issues with the framerate and PTS/DTS.
I will post a separate mail on this.

Regards (and happy new year), SF.

I believe you can set this with -video_track_timescale 24000

Not sure about the other two.

Unable to create and execute files in /tmp.  Set the TMPDIR environment
variable to another directory and make sure that it is not mounted noexec.
Sanity 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.

Subject: [FFmpeg-user] Saturation adjustment only in some channels
Message-ID: <20131231202416.GA8506@cons.org>

I am doing color corrections on a video.  Used gimp to find the
correction adjustments.

I have two difficulties:

1) I need to apply saturation only to cyan (leave red alone). This
   isn't directly supported by the hue filter.

2) how do I clip a color? (the equivalent of using gimp color levels
   and moving left or right slider, or in color curves move one end of
   the curve on the x axis) I think it works reasonably fine but just
   pushing the highs of the color, can somebody confirm that.

In general, how do ffmpeg's colorbalance filter's ideas of low, mids
and highs translate to color curves? How much overlap do they have?


Anyway, problem #1 is far more important.  I need to really kill cyan
saturation and I verified that the outcome isn't good if I either kill
red, too, or if I replace red saturation with more red (captain
obvious has spoken).

I am willing to throw significant CPU power on this so if I have to
separate out the whole thing into red and rest, correct saturation and
blend them together afterwards I'd do that, too.

Or maybe I can specify a table that simply translates every possible
color value to a target value?

Thanks for your help.

Just looking at http://ffmpeg.org/ffmpeg.html#X11-grabbing and see the
argument

 -video_size cif

but so far have come up empty on what "cif" means?  In context I'm
guessing it means 'same as source' (Copy Input/Image Format?) but just
curious for sure, or what other keywords might be put there.

From http://ffmpeg.org/ffmpeg-utils.html#Video-size

Specify the size of the sourced video, it may be a string of the form
widthxheight, or the name of a size abbreviation.

The following abbreviations are recognized:

...
?qcif?

    176x144
?cif?

    352x288
?4cif?

    704x576

...and the list goes on.

This is not a problem with ffmpeg: it is a problem with your system. You
need to make sure /tmp is not mounted with noexec. You can see if
noexec is shown for /tmp:

$ mount | grep tmp

You can remount /tmp without noexec, or set the TMPDIR environment
variable to another directory and make sure that it is not mounted
with noexec.
