This is actually a bug in amerge, it is the same if you change
asetnsamples with anull.

Please try to use a reasonably recent version of ffmpeg before asking
questions to ffmpeg-user: older versions aren't supported here!

Using "-vcodec mpeg4" and "-vtag xvid" works fine for me to play it on DVD.
Some resolutions, though, can't be played. So I'd suggest you to use
predefined resolutions
like vga, svga, sxga etc.

But even mediainfo showing that there is a subtitle stream, I cannot visualize it neither with mplayer, vlc or xine or demux it with ProjectX (which is possible using the uncut original recording).

Sorry for the long delay. Here is another example using ffplay:

1. ffplay output playing the source file. DVBsubs are shown!
2. the cutting with ffmpeg
3. ffplay output of the cut file. A subtitle stream is shown but the streams seems to empty (no subtitles are shown on the screen).

Hi,

 

Could you please let me know if there is a way to encode or convert videos
to H.263++ (H.263 2000) codec in a 3gp container? I am not sure if it can be
done using ffmpeg.

 

Most of the mobile devices support (also as per 3GPP PSS spec) H.263-2000
codec.

 

Looking forward to your response.

 

Thanks,

Pinakee

Subject: [FFmpeg-user] rtmpdump works / ffmpeg fails - swf verification and
	saving a stream
Message-ID: <1346503320.19408.20.camel@DESKTOP-TOYROOM>

I have a rtmpdump command that succeeds in downloading a stream from
ABCtv Austalias iView service


rtmpdump -V --rtmp rtmp://cp53909.edgefcs.net:1935 --app
'ondemand?auth=daEd5bbb.djagdyb5cNcNblcidmb0b3atbV-bqqFvX-8-qlm_tHAnL&aifp=v001' --playpath mp4:flash/playback/_definst_/catalyst_13_15.mp4 --swfVfy http://www.abc.net.au/iview/images/iview.jpg  -o /home/god/Videos/catalyst3.mp4

The above command downloads the whole file. But when I try and convert
it to a similar command for use with ffmpeg [below] it fails. (I need to
use ffmpeg because I am writing a plugin for the Serviio media server)

ffmpeg -report -i
"rtmp://cp53909.edgefcs.net:1935/mp4:flash/playback/_definst_/catalyst_13_15.mp4 app='ondemand?auth=daEbQaza1aTbSa7dZbXdTavcLa9dVcEdhdX-bqqFHH-8-lkq_uEwoJ&aifp=v001' playpath=mp4:flash/playback/_definst_/catalyst_13_15.mp4 swfUrl=http://www.abc.net.au/iview/images/iview.jpg swfVfy=1" /home/god/Videos/catalyst3.mp4

I few points about these commands. I need to to swfVerification on these
streams and I am using http://www.abc.net.au/iview/images/iview.jpg as
the .swf file to verify against. The syntax in rtmpdump for --swfVfy
switch is "--swfVfy|-W url URL to player swf file, compute hash/size
automatically" Normally the swfVfy URL would be a .swf file. But I
believe this service has renamed a .swf file to a .jpg to obfuscate a
bit. 

There are 3 reasons why I believe the verification URL is the iview.jpg 
1. The file is not really a jpg - will not display in the browser as one
2. Using it works in rtmpdump
3. Not using it but using a swfsize and swfhash matching it also works.

To reproduce this issue you might need to live in Australia (geo
blocking on the iView stuff). And you need to get auth tokens from
http://tviview.abc.net.au/iview/auth/?v2

Is this difference in behavior between rtmpdump and ffmpeg an issue with
my translation of the commands  - annoyingly it appears the parameter
named swfVfy is a URL in rtmpdump but a true/false switch in ffmpeg - so
I might have stuffed up something.

Or does this difference reflect some sort of issue with ffmpeg - perhaps
how it behaves when ask to do swf verification on a file without a .swf
file extension?

Hello everybody, i am trying to create a waitForPlayDone(  ) function, but
i am not having good results, ffplay with only the file to play as a
parameter does not tell us when the file ends to play. I took ffplay as my
base code.

Thanks.

Subject: [FFmpeg-user] Unknown encoder 'libx264'
Message-ID: <1346462850189-4653121.post@n4.nabble.com>

Hi,

I have a problem with ffmpeg, always when i try to encode a video with this
line: 
ffmpeg -i "mov.mkv" -an -b 700k -r 25 -vcodec libx264 "output.mp4"
on my vserver (debian 6.0), the error message Unknown encoder 'libx264'
appears. 
I used this tutorial to install ffmpeg
http://www.zoharbabin.com/build-and-install-ffmpeg-and-x264-on-debian-squeeze-the-dumb-guide.

Here is the full output of the console:

You need to compile with --enable-libx264.

The tutorial has errors and is not including libx264 when compiling.

The configure line when setting up for the ffmpeg compile needs to include "--enable-libx264"

This is a terrible guide:
* Development packages for x264 and ffmpeg are listed as dependencies
  although you are going to be compiling x264 and ffmpeg from source.

* It installs stuff outside of the package management system.

* '--enable-shared' is used for almost everything for no apparent
reason.

* Several useless packages are installed (libfaad-dev) and some
  external libraries are very questionable as to their usefulness for
  the general public.

Most importantly (and the reason for your error):
* None of the many external libraries that are installed are actually
  enabled in the ffmpeg configure step! To enable libx264 you need
  '--enable-
  gpl' and '--enable-libx264'.

I recommend reverting everything the guide does and adapting this sane
guide for Ubuntu:
http://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide

...or the Hardy version might be more suitable for you (I'm not sure of
the status of Yasm in Squeeze):

This package is unnecessary if ffmpeg is going to be compiled from
source. libavcodec-extra- 5* is only recommended if you are insistent on
using the crappy version of "ffmpeg" from the Ubuntu repository.

Subject: [FFmpeg-user] ffmpeg ac-3 encoding speed
Message-ID: <BLU0-SMTP145A28D6C9EB61174C5D4C3A7A50@phx.gbl>

I am encoding ?dts (DTS), 48000 Hz, 5.1(side), s16, 1536 kb/s? to ?ac3,
48000 Hz, 5.1(side), flt, 640 kb/s? with this command:

ffmpeg -i %tmp_orig_audio% -c:a ac3 -ab 640k -q:a 0 %tmp_enc_audio%

Now, on an Intel i3 machine using only one core, approximately 60sec of
this DTS stream is converted each second. It is almost as fast as the disk
can write and read.

Is this encoding speed normal or am I doing something wrong? I remember
that encoding stereo with LAME on high compression was much much slower. So
I wonder whether the quality of the resulting AC-3 stream is optimal? Can
it be tweaked?

In the end, that's what I did. I'm reporting back, for anyone who searches the 
archives for the same information.

Things got a bit easier when I found that 'ffprobe -show_frames' would give tons 
of information about frame types and times.

My source file had i-frames at regular 0.5s intervals, and only p-frames 
otherwise, so I didn't have the complication of b-frames.

To create an artificially bad situation, I used FFmpeg to produce a 30s file 
with a GOP of 300 (an i-frame every 10s at 30fps). I then asked it to 'copy' the 
file starting at 5 seconds in.

What I got out was very interesting. The sound frames started at the beginning 
of the file at 0s, from 5s into the original just as I had asked. There were NO 
video frames at all until the first i-frame, which was originally timed at 10s, 
but was now timed at 5s in the new file because of my cut. In a way, this makes 
perfect sense, but it seemed odd that I now had a video file which had five 
seconds of sound with no picture at the start!

(As a side issue, I noticed that FFmpeg had re-ordered the frames, the original 
had a bunch of audio frames, followed by a bunch of video frames; FFmpeg 
interleaved them more chronologically.)

I was curious to know how this file would play. VLC obediently played the sound 
right from the start (at the 5s point of the original, of course) and continued 
to show its orange cone logo on the screen. At the 5s point when the first 
i-frame came along, the logo was replaced with the video. It was perfectly 
synchronised. This is obviously a good result.

My only remaining concern was that my video editor (I use Vegas) would mess up, 
and ignore the frame times, leaving me with audio and video that were 5s out of 
synch. When I loaded the file in, I noticed that there was no missing 5s of 
video, as there had been on VLC. However, Vegas did not go out of synch, nor did 
it cut off the first five seconds of sound: what it did do was to grab that 
first i-frame and stretch it back to the start of the file. So the video was 
'freeze framed' for five seconds while the audio was playing, then at the 5s 
point it continued perfectly.

After these experiments, I'm confident to use FFmpeg to cut the garbage out of 
my 'original' footage, but knowing how this works, and having observed the 0.5s 
GOP on my original, I will also specify a start time that causes an i-frame to 
occur at the start of the cut file, for the cleanest result.

As I was saying before the cat walked on the keyboard...

Can I suggest that this is a good example of the way documentation should go:

http://msdn.microsoft.com/en-us/library/windows/desktop/dd390352(v=vs.85).aspx

I cite this not because it describes software that has a similar purpose to ffmpeg (though that doesn't hurt), but because I was able to understand and use directshow using that in a matter of a few hours, and directshow is a notoriously complex beast.

Yes, I know it's Microsoft, and I know they're spawn of satan, etc, but MSDN is a thing of extreme beauty (in parts at least) and it's hard to argue with them on a documentation front. Useful as a function list is, it doesn't describe how to use the thing. Each function needs examples and a writeup on likely use cases.

I occasionally make money as a technical writer and I would be pleased to help out with this - if I had the slightest idea how it was all supposed to work.

Thanks rodger, i didnt know that there is a libavcodec list too.
Anyway, your comment that 1024 may be just some default brought me on the 
right way again! It seems that one can set the framesize but you may not 
vary with it, depending on the capabilities of your encoder.
I will solve the problem by having some audio queue that is able to deliver 
as much samples as the default frame_size of the codec wants to have.

cheers,
harald

I think it's just some default.

You may get more help from the libav-user group.
As a note I recently used the asetnsamples filter to force a specific
sample size, if that helps at all.
Cheers!

Subject: [FFmpeg-user] libvo-aacenc
Message-ID: <5043CEF5.20601@gmail.com>

I'm having trouble encoding with aac. It seems that the current working version 
is "libvo-aacenc", and it's listed as enabled, but it's complaining that it's an 
unknown encoder. This time, I'm posting the whole command/output because I might 
have made a mistake - anyone?

P.S. I'm not fussy, I'll take ANY method of encoding AAC that actually works, 
even if it's crap.

Thanks

Hi
In the FFmpeg command libvo-aacenc needs an underscore(_), not a hyphen(-).

If you need slower encoding speed, try building with --disable-asm or 
--disable-optimizations or both.

Please remember that this version of FFmpeg is intentionally broken, 
has several hundred regressions and since some of them are possibly 
security relevant, this version cannot be supported on this mailing

I don't think there is anything wrong with installing current git head

Well, that's a clear as mud. Even now you've told me, I can't imagine why, given 
that it's declared with a hyphen in the output.

(I was a victim of google, btw; because of the way I searched for help, I found 
only broken examples. My bad. And this is the first codec I've used that has a 
word break.)

I tried loads of permutations of "libvo-aacenc" but never had any inkling to 
change the hyphen...

Thanks. Works now.

I was trying different options for -r , starting from 16 to 50, still remain
the same. I'm able to stream maximum the 200 frames then it's crashing.

This kind of behaviour is often configurable in the player or editor. I.e.
there might not always be a sure-fire way of determining player behaviour in
the encoder, just bear that in mind.

If all else (with ffmpeg) fails, Avisynth's Interleave filter should do the
job:

"Interleave
"Interleave (clip1, clip2 [, ...])

"Interleave interleaves frames from several clips on a frame-by-frame basis,
so for example if you give three arguments, the first three frames of the
output video are the first frames of the three source clips, the next three
frames are the second frames of the source clips, and so on."

Yes, but then I will not use any CPU optimizations, so the quality will 
be the same.

My question is rather whether I can _improve_ quality of the resulting 
AC-3 stream by possibly reducing the encoding speed.

Message-ID: <CAN=PG0gvgGc2UEjmS3e730S9gLM-30imqxD=K55zaRRXFDtgpw@mail.gmail.com>

I apologize if this has been asked/answered before but searching the
lists didn't turn up anything useful that I hadn't already tried. I'm
trying to use ffmpeg in a screencasting setup where I take 2 pulse
inputs (microphone and system audio), video with x11grab, and then
output to an RTMP server. I use the filter_complex parameter with amix
to mix the 2 audio streams, and the async filter to prevent audio
desync.

The async filter appears to be working properly as I had issues with
increasing desync before (it was roughly 0.5 seconds of added delay
per minute), and adding the filter resolved that issue in limited
testing. However, the audio is still consistently 1 second behind the
video.

My base command was this:
$ ffmpeg -f x11grab -s 1920x1080 -r 25 -i :0.0+1280,0 -f pulse -i

I tried using -itsoffset to delay the video by 1 second:
$ ffmpeg -itsoffset 1.0 -f x11grab -s 1920x1080 -r 25 -i :0.0+1280,0 [...]

... however values for -itsoffset seemed to make the delay fall
further behind, as if it was applying it persistently to the audio
stream rather than the video stream. Normally I'd just adjust the
delay manually after the fact but unfortunately that's not possible to
do while streaming.

So, is there some way to either:
a) fix/prevent the initial audio delay between the mixed pulse devices
and the video; or
b) account for it with some sort of offset?

Thanks in advance for any help!

Could you elaborate?
I can't test at the moment, but I didn't find "libvo-aacenc" in 
the sources, so that is hard to understand.

(Was that really your original question?)

Iirc, the ac-3 encoder takes exactly one quality option: -ab
Perhaps one of the options that you see with ffmpeg -h 
("AC-3 Encoder AVOptions") also affects quality, I am not sure.

(Yes, that was the original question... or at least what I meant.)

Afais, the options that might effect quality per bit in a positive way 
are enabled by default.

OK it works with this setting (on an updated git HEAD), but not with my
original, or with no vtag set at all.

Must just have been fortuitous that it worked before....

Not a typo in that its what I intended, Since the file is uyvy422 it
seemed logical to keep the same uv order in the 4CC!

Sure. It's actually there in my original post. Here is a section of the output:

ffmpeg version N-43594-gf0896a6 Copyright (c) 2000-2012 the FFmpeg developers

ble-zlib

I observe that the configuration includes "--enable-libx264" and "libx264" is 
the name of the codec used in a command. Therefore, when I observe that the 
configuation includes "--enable-libvo-aacenc" I deduce that "libvo-aacenc" is 
the name of the codec to use in the command.

As someone who understands configuration, compilation and library issues, it's 
probably so obvious to you why this happens (I have no doubt it arises from 
different conventions on whitespace substitution) that you didn't even notice; 
but to me as a user, it's confusing.

Thank you.

The version you posted had local patches (at least I can't 
checkout the version here), I believed that I looked again at 
this issue after my last post, and it seems completely 
impossible to me that this has ever worked the way I understand 
your posts. Note the "raw " above that simply means that no 
software has any chance to guess what you stored in your file.

Strictly speaking, this is not "output" but input, because it 
is the configure line used by the person who compiled your 
binary (you?), underscores are not used in FFmpeg's configure 
script (I don't remember why).

The relevant command line to find out the names of the aac 
encoders would be:
$ ffmpeg -encoders|grep aac

(or ffmpeg -codecs with older versions)

Oops, that would probably have been a couple of doc tweaks, or maybe
forced interlaced scaling. But going by the build date and number it
would have been based around 13ba872a2a7f

As the parameters were in a script (to avoid inconsistencies due to
typos) ;) I know it wasn't a one off, but to be honest as its working
now I am more curious as to why the 4CC lists the vectors in the wrong
order compared to the way they are packed, it seems a tad inconsistent!

Complete ffmpeg console output is missing. Also, you're applying -q:v 2
as an input option. Option placement matters.

I'm wondering if you've made a command line that's just too long by using the 
single-quote syntax. Could you use something like

ffmpeg -f image2 -i IMG_%04d.jpg -r 30 -q:v 2 timelapse.mp4

because I believe that makes FFmpeg do the expansion, not the shell.

(There was once a restriction on how the files were numbered, i.e. starting from 
0000 or 0001, not sure if that's still valid. Untested command example.)

Thank you for the replies.

My filenames are in the format YYYYYY-MM-DD-HHMMSS.jpg, for
example 2012-09-03-121544.jpg. So I didn't want to have to rename (or make
hard links) in the format %04d.jpg. I found that ffmpeg can do globbing via
http://murphyrandle.com/blog/2012/08/03/ffmpeg-can-handle-the-globs/

However, it turns out that the problem is with my input data. The ~1000th
image was corrupted (zero bytes) and so it seems ffmpeg aborted due to
that. I deleted the malformed image and re-ran the command `ffmpeg -i
'%*.jpg' -r 30 -q:v 2 timelapse.mp4`, and it worked perfectly.

Thanks!

(I may be wrong but I suspect you just found out how 4CCs are 
defined.)
I just tested (again) to encode uyvy422 rawvideo to mov using 
current git head and an ancient version: In both cases, it worked 
as expected with -vtag 2vuy and did not work without -vtag.

Please understand that FFmpeg developers are generally very 
interested in regressions, but I cannot reproduce a regression 
in this case and I especially can't imagine one so far.
If there really is a regression, please provide command line and 
complete, uncut console output for a revision that I can checkout.

Subject: [FFmpeg-user] Gnarly ffmpeg multi-stream demux challenge test clip
Message-ID: <50455A98.2070602@davidfavor.com>

Attempting to demux (copy) two video streams from
one video to another, dropping the audio.

These video clips are Skype recordings with one
video and one audio track per each caller in a
group call.

The audio has to be extracted + normalized, which
works fine.

Problem is the video. The source video plays/previews
in QuickTime with each video side-by-side. The source
video also works great dropping into other video editors
like ScreenFlow or iMovie.

Attempting to copy only video streams (audio dropped)
produces an output file with all the videos stacked
on top of each other.

The output video is uneditable by any software I have.
No way to move videos from off the top of each other.

There's a copy of the source video here:

     http://DavidFavor.com/private/2012/foo.skype.mov

There's a YouTube video detailing the challenge here:

     http://YouTube.com/watch?v=eabMRPb5zEQ

The command I'm using for the extraction is:

    ffmpeg -y -i foo.skype.mov -an -vcodec copy -map 0:2 -map 0:3 foo.video.mov

The output stream mapping appears correct:

    ... ... ...
    Stream mapping:
      Stream #0:2 -> #0:0 (copy)
      Stream #0:3 -> #0:1 (copy)
    ... ... ...

Here's a stream dump of the source video and a complete dump of the
ffmpeg output from the extraction command.

I'd appreciate an ffmpeg guru passing along the correct syntax.

Thanks!

I've just been battling the same thing with a Philips DivX player, the DVP3140. 
I wouldn't have started if I'd known how many hours and blank DVDs I'd waste.

I won't bore you with the saga, but the bottom line is that this kind of player 
is quite fussy (since I have a life outside video conversion, I forgot what this 
player would take, vs. my WD Media Player which is more versatile). It refused 
to even TRY to play anything until I set the FourCC to "DIVX" (I think it 
accepts XVID too) then it would fail. (Symptoms were that it would appear to 
start, blank screen, time counter would "race" at many times real time; I think 
it was reading the file flat out, looking at frames and displaying the time, but 
not finding a frame it liked. Pressing "stop" restored the menu.) The 
breakthrough for me was discovering that there was an actual codec named 
"libxvid" whereas I'd been trying mpeg-4 because I thought that's what DivX was.

Just for the record, the command that worked for me was:

c:\ffmpeg\bin\ffmpeg -i input.mkv -sn -c:a libmp3lame -ar 48000
-ab 128k -ac 2 -c:v libxvid -crf 24 -vtag DIVX -vf scale=640:480
-aspect 4:3 -mbd rd -flags +mv4+aic -trellis 2 -cmp 2 -subcmp 2
-g 30 -vb 1500k output.avi

(This was for an old TV show, to be displayed on a CRT 4:3 screen; a different 
scale and aspect would probably be better for modern stuff.)

I can't say this will work for anyone else, just saying it worked for me on what 
is now a 'dated' and fussy DivX player.

Hi,

I go on with searching the best way to convert HD-1080i content to SD-576i
content, with losing the minimun detail... :-O

Well... I have making some new tests... but when transcoding from HD 1080i
to SD-PAL the video loses a lot of detail (i.e., 720x576i video is a little
bit blurred)

I have tested with this option UNSHARP filter in order to get a SHARPer SD
content: $comando="ffmpeg -y -threads 8 -i ".$input_file.".mxf -pix_fmt
yuv411p -aspect 16:9 -vf
\"scale=720:576:interl=1,fieldorder=bff,unsharp=7:7:2.5\" -vcodec dvvideo
-map 0:v -map 0:a:2 -ac 2 ".$output_file.".dv";

But there is a problem... unsharp filter is acting with frames and not with
fields. So, the video after filtering gets a wrong output: blinking.

Is there any way to use "sharp filter" with fields and not with frames?

Many Thanks in advance!!

Iban

I have never got it to work without the vtag, but as per below with the
wrong vtag on the revision I previously mentioned, but not with the
wrong vtag on more recent builds.

If I recall correctly, the default vtag/FourCC for 4:2:2 UYVY in
FFmpeg is "HDYC," which is the FourCC for the AVI format. However,
QuickTime/MOV uses "2vuy" which is why the MOV muxer fails when you
don't force the vtag to "2vuy." In fact, Blackmagic released a simple
app a while back called "FourCC Changer" for Mac that did nothing but
change the FourCC from HDYC to 2vuy in case you wanted to open a
Blackmagic 8 bit uncompressed AVI in a QuickTime application.

Message-ID: <ED656729-19E4-49BA-9307-23E0F28A43F5@axz.ro>

Fellow ffmpeg users,

I have 2 TS files that have been split (by a vdr recorder): file1.ts and file2.ts.
file1.ts ends with x miliseconds of video that don't have audio packets because they are actually at the beginning of file2.ts.

How can I use ffmpeg to construct a synchronized file1 by taking the missing audio from file2.ts ? 
I hope this could be done intelligently by using the PTS information in each file, I just don't know how. Please bare in mind that x is variable for every split.

Your help would be greatly appreciated.

Thanks for your time,
Rares

Message-ID: <1346749445870-4653178.post@n4.nabble.com>

Hi,

Can anyone tell me if ffmpeg is capable of creating multiple programs in an
mpeg TS?

Has created two kinds of TS videos, I give the options below.

#VideoOption 1
./ffmpeg -i ../ts/tt.wmv -c copy -mpegts_original_network_id 0x1122
-mpegts_transport_stream_id 0x3344 -mpegts_service_id 0x5566
-mpegts_pmt_start_pid 0x1500 -mpegts_start_pid 0x150 -metadata
service_provider="Some provider" -metadata service_name="Some Channel" -y
output/out.ts

#VideoOption 2
./ffmpeg -i ../ts/tt.wmv -c copy -mpegts_original_network_id 0x156E
-mpegts_transport_stream_id 0x339E -mpegts_service_id 0x55CA
-mpegts_pmt_start_pid 0x1564 -mpegts_start_pid 0x1B4 -metadata
service_provider="Some provider1" -metadata service_name="Some Channel1" -y
output/out1.ts

So the out.ts, out1.ts ts file to one of the files I'd like to create. I
would like to know the options.

Sorry I failed to figure this out through the ffmpeg documentation.

Thanks for any advice

js,
Park

(I originally failed to see the problem because -vtag is 
completely superfluous in above command line and one 
could even argue ffmpeg should protest when given an

MPlayer has the "il" filter to deinterleave (and after unsharpening 
interleave) fields. It has not yet been ported natively to FFmpeg, 
but you could use -vf mp=il=d to deinterleave.
Unfortunately, afaict it needs yuv422 input to work correctly, so 
you will have to do additional scaling...
(Or fix the filter.)

You just beat me on the bisect, must have a faster machine....:(

I would agree that would be a more sensible approach to warn. I only
just spotted it was being silently corrected/ignored in the versions
that worked.

However if the vtag is superfluous how come the file wont play unless it
is included?

It does indeed make sense. This is not the preferred design at this time,
though: currently, filters with several inputs are expected to work by
themselves to ensure proper sync. Actually, "preferred" is a bit of a
stretch, there are currently only three filters with that kind of features:
overlay, amerge (work like that) and alphamerge (requires frame-exactness,
fix in TODO list).

Of course, it can be discussed, but I am affraid that an API to do that kind
of thing automatically with additional filters would be very hard to design,
especially if it must be nimble enough to allow various combinations.

I believe that having queues inside the private context of the filters and a
set of well-thought helper functions to handle the various cases is a
simpler and more robust approach.

[trimmed]

That guide is outdated and uses the really old, messy way of encoding
with libx264. It is recommended to use the libx264 encoding presets
instead of declaring each (depreciated) option. See examples here:

You're using old source. FFmpeg has not used SVN since 2011-01-19. See
a compiling guide if you need help:

On windows I would use "copy /b file1.ts+file2.ts file3.ts" and then use
ffmpeg to process file3.  I'm not sure of the bash equivalent. "xxd -b" ?

I'm still not sure that sharpening is a good idea on interlaced, but 
it's not my video and I suppose it's more likely not to be played on a 
"real" interlaced display than in the past.

Prompted by this thread I had a look at what the BBC scale was like by 
recording HD and SD channels showing F1 at the same time.

TBH their SD looked quite soft and I could get something sharper looking 
at the same bitrate just using lanczos.

For some strange reason my version also deinterlaced better than theirs 
  - I maybe lucked into that one. Sometime I am going to repeat and see.

 As I have been noticing youtube-dl downloads were corrupted way more

~
 Other users had noticed it as well
~
 https://github.com/rg3/youtube-dl/issues/411

 How could ffmpeg (probably probably in tandem with scanning/binary
comparison utilities) be used to check how (the metadata and/or the
payload) of those media files differ?

If VLC works ok with it but ffmpeg not, and you have an easy way to

This works for me in windows:
ffmpeg -i concat:"lame1.mp3|lame2.mp3" -acodec copy yo.mp3

So my guess is you don't want to escape those pipes.

It seems from your youtube that it only "sees one side" in playback,

Yeah.  I was kind of hoping the astreamsync filter would be enough for
this particular case, when combined with asetnsamples.  Except the
latter is buggy so it definitely isn't enough today :)

Yeah that would help.
I suppose I'll work around it for now.

I had a quick look and it looks to me that the two videos would need
some form of pan & scan vectors to be able to be two separate streams
and appear side by side in the original capture. I'm not in any way
familiar with the formats in use (is there anything other than H.264 and
.mkvs teehee) but that's where I'd look to see if they were being
dropped when the stream were copied. You'd get both videos decoding, but
displaying on top of each other. This would match the fact you have 2
video streams, but only one plays.

I don't know if mediainfo has this level of detail (or even if the
streams are capable of supporting P&S in this way).

Yes,

URL Sample TS file multiple channels of BBC, is made of a single TS stream
file.

Sample as one of the TS stream file, and I want to have multiple Programs.


I would like to know the option to create one TS file into more than two
video.

Ok so multiple channels into a single TS file.

I know you can include multiple channels with the -map method, however
I'm not sure about setting TS program ID's...

Thank you.

But I do not know how to use -map.
Doc listed in the-map option, do not know how to add a channel.

I'm sorry, but
for the additional channel-map option, I would like to know how to use.

And set changes, the PID is difficult ............... :'(

Or If you have a constant index for each channel so you know when to demux.

Out of curiosity, what are peoples' thoughts on adding some basic
crash course "getting started" stuff on what (raw) video and audio is
and how they work, what codecs are and how they work, and what format
containers are and how they work? This would be a significant addition
(as in time consuming to do a good job), but I think it would help
people have a one-stop intro to using libav* (plus the info wouldn't
get outdated as libav* progresses). I've met a lot of people who
expected video/audio to be simpler when they wanted to add it to their
application and got lost in the midst of trying to understand both
video and libav* (or whatever other libs they were using).

I agree.

If you absolutely MUST sharpen, what usually works best is to use a
specialist deinterlacer > sharpen > re-interlace. A good example of such an
interlacer would be Avisynth's QTGMC.

But in my limited experience with DV, perceived loss of detail is usually
caused by less-than-optimal resizing or (unexpected) colourspace conversions
and/or imagination! Remember, chances are you're watching the interlaced
output on a progressive display as suggested by Andy. With a player lacking
dedicated interlaced support this will make the output look worse than it
is.

Those messages are caused by using old syntax on a newer version ffmpeg. The
best route forward is to optimise your command line using the guide Lou
suggested. The quick and dirty way is to add the :a and :v specifiers as
suggested above, and to substitute current option names for the ones giving
errors. Between the documentation and command line help I could find them
all except one I had to look up in the code, hopefully you don't use that
one ;-).

The only one I'm unsure of is whether wpred is equivalent to weightb,
perhaps someone can confirm.

This should help:
http://www.ffmpeg.org/ffmpeg.html#Stream-selection
and
http://www.ffmpeg.org/ffmpeg.html#Stream-specifiers-1

This brings me to a question however. According to the command line, usage
is:
-map [-]input_file_id[:stream_specifier][,sync_file_id[:stream_s  set input
stream mapping

What is that [-] used for?

Subject: [FFmpeg-user] Problems decoding h264 from Blu-ray
Message-ID: <CAKYWZ4fvBE3A3Qubyjna8unOF0hVS7fUnSYhJqq541_oUbBqvw@mail.gmail.com>

Hello,
I have trouble decoding the H.264/AVC stream of an unprotected Blu-ray
(m2ts container) with ffmpeg (on Windows). I tried the zeranoe's
Windows build and my own. Both fail to decode the stream *at different
positions* with errors like these:

cabac decode of qscale diff failed at 62 61
[h264 @ 0000000003985840] error while decoding MB 62 61, bytestream (59232)
[h264 @ 0000000003985840] concealing 827 DC, 827 AC, 827 MV errors in I frame

[h264 @ 0000000003985840] left block unavailable for requested intra
mode at 0 60
[h264 @ 0000000003985840] error while decoding MB 0 60, bytestream (78993)
[h264 @ 0000000003985840] concealing 1009 DC, 1009 AC, 1009 MV errors in I frame

top block unavailable for requested intra mode at 97 16
[h264 @ 0000000003985840] error while decoding MB 97 16, bytestream (202101)
[h264 @ 0000000003985840] concealing 2112 DC, 2112 AC, 2112 MV errors in I frame

These errors result in blocky image errors in the output file.

Command line: ffmpeg.exe -i 00000.m2ts -report -loglevel verbose
-codec:v libx264 -preset:v veryslow -profile:v high10 -tune:v
animation -level:v 5.1 -refs:v 16 -subq:v 11 -me_range:v 24 -bf:v 16
-trellis:v 2 -x264opts
"rc_lookahead=160:psy-rd=0.4,0.15:aq-mode=2:aq-strength=0.6"
-chromaoffset:v -3 -crf:v 15 -codec:a libfdk_aac -b:a 200k -sn
-threads 4 asa-10.mkv

m2ts info: http://pastie.org/4668776

Full ffmpeg log (canceled after errors occurred): Warning: large (3MB)
https://dl.dropbox.com/u/17527004/ffmpeg-20120905-152133.log

The video plays fine in VLC player and MPC (using codec: ffdshow
libavcodec h264) and the decoding errors appear at different positions
so I think the input video should be fine.

Does anyone have an idea why the decoding fails and how to fix it?

Thanks!

Yeah some intro would be helpful.

That I certainly can write - in fact, I've written that sort of intro many times before for various people. There are a couple of problems, though, mainly that I'd like to see a decent amount of progress on the API technical side of it before committing the time.

I noticed that "by default" when I compile fontconfig as a static

presumably, because it is running pkg-config like this:

$ pkgconfig pkg-config --libs fontconfig

which outputs:

-L/home/rogerdpack/dev/ffmpeg-windows-build-helpers/builds/mingw-w64-i686/i686-w64-mingw32/lib
-lfontconfig

after consulting the fontconfig people, they suggest this work around:
$ pkg-config --static --libs fontconfig

which outputs this:

-L/home/rogerdpack/dev/ffmpeg-windows-build-helpers/builds/mingw-w64-i686/i686-w64-mingw32/lib
-lfontconfig -lexpat -lfreetype

and works.

So the question is, if it would be possible to call it like that
instead somehow?
Anyway just wondering.
Thanks!

Subject: [FFmpeg-user] Selecting/cutting small sections of videos with ffmpeg
Message-ID: <CABSuK1MPq69sewo6LS5kYiLw-0MegNv6DLy3SrnTUinJxd_PMQ@mail.gmail.com>

I'm very much a novice user of ffmpeg, and I'm using it with the windows
command prompt. I have 7 second long, 25fps, mp4 videos and I'm tyring to
cut out small 2 second sections of them using ffmpeg.

The problem I'm having is I cant get it to cut properly if I specify a
start point other than the beginning of the video.

Originally I was running this command:-

Code: ffmpeg -i full.mp4 -ss 3 -t 2 -vcodec copy -acodec copy cut.mp4

This fails with errors saying I should (check -ss / -t / -frames parameters
if used) (paste bin of the error: http://pastebin.com/RWJ6wFZ1).

If i set -ss to 0 this cuts 2 seconds from the start and works fine.

Following some advice from IRC I tried this:-

Code: ffmpeg -i full.mp4 -vf select='gte(t\,3)*lte(t\,5)' -vcodec copy
-acodec copy test.mp4

This ignores the specified window and copies over the whole 7 seconds.

Could anyone tell me where I'm going wrong?

Many thanks,
Chris

Cl?ment, now, after some months, it seems supported:

"MOV	X	X"

but I can't make it work, and I've been searching and studying all day...

The command I'm trying to apply is:
ffmpeg -i <input.mov> -acodec copy -vcodec copy -metadata
timecode=15:14:13:00 <output.mov>
but I get nothing...

Do you have some advice?

Thank you very much

Gianluca

Try -timecode 15:14:13:00?

If it doesn't work, please paste the command line and full output, as well
as the output of ffprobe output.mov.

$ ffmpeg -i sintel.mpg -ss 3 -t 2 -vcodec copy -acodec copy cut.mp4

works for me here.  When you do
$ ffprobe -show_packets full.mp4

what is an example output?

The problem is that a MP4 file contains "I Frames" which are self contained, and 
other frames which are only differences, they're (usually) calculated from 
previous frames. A MP4 file may be entirely I frames, or at the extreme, may 
have only one I frame at the start, and then P frames (difference frames) from 
there on.

If you want to copy a file without recoding it, then you can ONLY cut it to 
start at an I frame. (You can finish anywhere.)

The behaviour of FFmpeg is that if you ask to cut at a certain time with -ss 
then it will scan through the file to that point, then continue to scan forward 
until it finds an I frame, and then copy from that point on. Unless you 
carefully calculate your start point to coincide with an I frame, then you will 
lose some video.

Your clip is so short that I suspect that there isn't even a single I frame 
between your start point (3 seconds) and your end point (2 seconds later). In 
this case you will get no video at all, which is exactly what your error says.

Thank you for posting your output, I guess the other respondant didn't notice 
the link.

I assume this is the same problem when one tries to put an x264 in a
.mpg container?

Thanks!

Also WMP can't seek on it "as well" as it can with the original, but I
suppose that's probably not related.

It does play with ffplay, but not with mplayer, so yeah, having it
"warn" people when they put potentially bad streams in containers
might be kind :)

Hi,

Thanks very much for responding. I've actually managed to solve this now
thanks to the help of a guy on the #ffmpeg irc channel.

Basically I'm now re-encoding the video but preserving as much of the
quality as possible using the following...

ffmpeg -i full.mp4 -ss 3 -t 2 -vcodec libx264 -crf 0 -preset placebo
output.mp4

Based on what I've now learned I realise I should have done this cutting
step before we compressed the videos from uncompressed avi to mp4. Sadly
it's too late since they've been deleted.

Many thanks for all the help, it's great that there's such a friendly and
helpful community around ffmpeg.

Chris

Hello,
is there any possibility that ffmpeg shows the time needed for encoding?
When using -report it doesn't includes it, only the video length.

David

Do you mean expected time needed, or actual time used?

If the latter, I use a shell script that records the time before and after
calling ffmpeg.

Don't know if this is much use to you, but in case all else fails...

Try channelmap filter. See the documentation:

You can try the -map_channel option.

If you have an avi with mpegvideo that plays in WMP than 
there may be a bug in FFmpeg and it would be nice if you 
could share that sample.

If you do not have an avi containing mpegvideo that plays 
in WMP than I suspect there is no bug in FFmpeg so you do 
not have to open a ticket!

The channelmap filter is crap, kept only for compatibility with avconv.

The correct filter to do that kind of work is pan.

Please let's try to avoid this terminology, and have respect for other

ffmpeg-user random tip #30
The -n option will force ffmpeg to exit if the output file already
exists, without to prompt you for confirmation.
Example: ffmpeg -i movie.avi -n movie.mp4

Hi,

I am not able to replay video from .ffm recorded earlier.ffplay or any
other player plays the file only when I feed the ffserver through
ffmpeg.

	(This is the third time I try to send this mail. Hope it goes through).

	What initial question? Whether the revision I said it worked actually worked? Yes, it 
does. And the revisions I said didn't work don't work. To quote my earlier mail:

	And version 3e1cf49 (as well as the following ones) fail.

The culprit was "libavresample".
After reading Michael's post about integration and support of  
libavresample in ffmpeg [1], I tried compiling without  
"--enable-avresample" and now it works.

Unfortunately, the reason why I had avresample enabled, was that I  
tried to fix a very strange A/V async problem using one of the audio  
filters [2] like "asyncts" or so. I don't remember which one it was  
which required libavresample, though.

However, what is the current opinion/status of libavresample not  
compiling with the current git head?

Pb

PS: I think the problem causing the error message is that there's a  
placeholder "libavresample/x86/audio_mix_init.c" used in the "extern  
void" declarations of "ff_mix_ ## chan ## _to_1_*" routines. The  
define "DEFINE_MIX_3_8_TO_1_2(chan)" is called with channels 3-8, but  
my Debian Squeeze's compiler setup seems to be unable to handle this  
at the moment...

Are you absolutely sure that you reported this problem in a way 
that allows the developers to reproduce?

Since it works fine here with the sample you attached to 
ticket #1720 I suggest you use a more current MPlayer version.

Hello.
I know you can use libflite like

$ffplay -f lavfi flite=text="No more be grieved for which that thou hast done."

But I can't quite seem to figure out from the docs how to pass this as

Could anyone help me out?

Thank you.

Your answer, as I've tried it, I did not know.
I'm sorry, but I did not understand the answer.

I would like to know an example of a command.

I am now under the command created output.ts
But you can not see the channels I want. As the channels are combined, the
PID seems strangely changing.

Well I tried. Those errors occur randomly while decoding the video
(nothing to do with the encoder, they also happen when I decode to
rawvideo and discard the output). I tried to cut a scene (without
re-encoding of course) and upload it but even a scene where decoding
failed multiple times is fine when it is decoded alone. It seems that
the errors only happen after decoding about 5 minutes of the video.
Sometimes there are hundreds of decoding errors and sometimes only 1
in the 30 minute video. I didn't manage to decode it without errors,
though. Uploading a longer piece is not possible as it's from a 1080p
Blu-ray and a minute already hundreds of megabytes.

Tried with zeranoe's and my own build of 64bit FFmpeg using latest git.

The weird thing is that there are *no such errors* when decoding using
zeranoe's or mine *32bit* build of FFmpeg. I just found this out.
Using 32bit this is the only error in the whole 30minute clip and the
output video is fine every time:

> number of reference frames (0+3) exceeds max (2; probably corrupt input), discarding one

Maybe it's my PC, I already had failing RAM in the past or it could be
a CPU feature that's causing this and that is not available in the
32bit build. I don't have another PC to test it.
32bit is fine but the process is running out of memory (only 2GB on
32bit) because I need more memory to encode using my x264 settings so
I'd prefer to use a 64bit build.

Any idea what I could try?

Sorry for that but it was a 3MB large log that couldn't be pasted into the mail.

Okay, I thought it could be helpful to know that the stream has a
bitrate of 34.3 Mbps and other stuff that is noted there.

On a Mac, QuickTime has an export compression setting called "None", which
somehow applies no codec at all. Is there an equivalent setting in FFmpeg?
How do I get "no" codec?

Cl?ment, I've tried the command
*ffmpeg -i STD_0022.MOV -timecode 15:14:13:00 -acodec copy -vcodec copy
std_0022_tc.mov*
but I don't think I have any success. The timecode doesn't show up in QT 7.x
nor in FCP.
I don't have ffprobe and I currently don't have the tools to compile it,
since I understand there's no binary available for download. In the
meantime, I've called the resulting MOV file with *ffmpeg -i* and this is
the result:

hwo should anybody imagine "no codec"
no compression does NOT mean no codec

what is the output of "ffmpeg -i filename" for such a file?

        movenc: add timecode track support.

And:

    June, 7, 2012, FFmpeg 0.11.1

(and actually 0.11 is even older, .1 being just a bug fixes release)

So I believe your version is too old. Note that we highly recommend our
users to use the latest development version, which you can get on
https://ffmpeg.org/download.html.

You seem yo be looking for a Mac OS build, and unfortunately the static
build provided by tessus seem indeed limited to the release versions. I'd
suggest you to look into the wiki for detailed instructions:
https://ffmpeg.org/trac/ffmpeg/wiki/MacOSXCompilationGuide

So I tried rawvideo and argb and I think that's what I'm after. It's not
"None" like QuickTime says, but maybe it's the closest I'll get?

"None" isn't a technical term. If you look at your output from ffmpeg,
it reports the codec is "rawvideo" with an "argb" pixel format, even
though QuickTime is telling you "None." "rawvideo" quite literally
means raw (uncompressed, unprocessed) video.

QuickTime says "None" because that's a more user-friendly term for the
non-video savvy people, while ffmpeg prefers the term "rawvideo"
because it means a bit more to the video savvy, but in the end it's
the same.

>So I believe your version is too old.

Cl?ment, thanks for your help, but the 0.11.1 is exactly the version that
I've used, as reported in the output I had attached ("/ffmpeg version
0.11.1-tessus Copyright (c) 2000-2012 the FFmpeg developers 
  built on Aug 16 2012 18:49:35 with llvm_gcc 4.2.1 (Based on Apple Inc.
build 5658) (LLVM build 2336.1.00)/ ").
So I must be giving some incorrect command, I'm afraid.

For the ffprobe, I've found the windows build and used it, but the output is
exactly the same as the one returned by "ffmpeg -i" command.

I appreciate your help
Gianluca

That's what I was saying, 0.11.1 is the latest release but it is too old
anyway.

I hoped that I can measure only the time for encoding, not anythin else....
BTW do you know a tool with which I can record the fps while decoding. I
want to use it for estimate the codec complexity and the requirements on
hardware. Can ffplay do this?

David

the stdout displays fps...
also the -progress option (though I don't know it well) might be useful.

Hmm seems to be the same with a newer mplayer...maybe you could help
me figure out where it's working in linux but not windows?  Does your
output not show "Audio: no sound"?

Thank you.

Subject: [FFmpeg-user] Prores 444 being detected by quicktime as 422?
Message-ID: <5049EAA8.3060506@ringsidecreative.com>

I seem to be unable to generate a 444 prores .mov file that quicktime 
player will indentify as 444. QT Player claims the movie is 422.

Several misc. sources (one of which is 
http://transcoding.wordpress.com/2012/01/29/prores-ffmpeg/) quote 
examples of using the arg "-pix_fmt yuv444p10le" to generate 444 prores 
quicktime movies. However, whenever I use yuv444p10 or yuv444p10le 
ffmpeg presents the error:

Incompatible pixel format 'yuv444p10le' for codec 'prores', 
auto-selecting format 'yuv422p10le'

I have tried various source qt movies of 8 bit uncompressed, 10 bit 
uncompressed, 422 prores and 444 prores. The output movie is created, 
but is always 422 (in Quicktime Player) and ffmpeg displays the 
"imcompatible pixel format" message.

I have been told that ffmprobe identifies the file as 444, but quicktime 
player identifies the output files as 422.

I am using an ffmpeg win32 static build on Windows 7, 64-bit OS.

CommandLine:
ffmpeg-20120903-git-5d55830-win64-static\bin\ffmpeg.exe" -i 
"C:\Server\Jobs\Conversion\FlameOutput_Quicktimes\Car_10BitRGBUncompressedTC.mov" 
-vcodec prores -profile 3 -pix_fmt yuv444p10le -f mov 
"C:\Server\Jobs\Conversion\FlameOutput_Quicktimes\Car_10BitRGBUncompressedTC\Car_10BitRGBUncompressedTC.mov"

Correct.

.mkv is a no-go as no software really understands this format.

The resulting file has to be able to drop into QuickTime, ScreenFlow,
iMovie, Final Cut, Kdenlive...

Hum... mediainfo-7.6.0 output shows no directives about position
of videos, that I see... Here's the output...

Subject: [FFmpeg-user] Problems when I move the window.
Message-ID: <CAL5dx5Tay9s7wf56HQ_MPY+GtsUzK0cFzu7xQ99kQ2VtB2ga6g@mail.gmail.com>

Hello everybody, I have created a .lib and .dll files based on ffplay to
play videos. I use the library to create a example en c, then when I move
the window frame or minimize the window there is no problem. But this lib
and dll were build to be used in java. So I create my example in java with
jni. But when I move the window or minimize it, the video stops and only
the audio is played.

I don't know if any of you can help me to fix this.

If you know a resource which talks about injecting pan + scan vectors
into .mov containers, pass along the link.

Thanks.

Nope, sorry. I'm exclusively avi and mkv here. I was hoping the
information would give you a pointer to what is wrong with the resultant
file.

Aw well. Maybe someone else has a clue.

I'm baffled.

Nope, just a decoder.

Subject: [FFmpeg-user] help remuxing mp4 to matroska
Message-ID: <CALG+B2v=jdx3nyt8DP6rg9Se3p=QD2b4T46TAVbnrfoBgzc0zg@mail.gmail.com>

Hello,

I am not an ffmpeg or multimedia expert. Bear with me. I am trying to
transmux an mp4 file with h264 video and aac audio to matroska using
libavformat, libavcodec, etc (i.e. not command line ffmpeg). My
understanding is that no decoding or encoding is required. That is, I
believe the matroska container can handle h264/aac, and that I have
these bytes available, and therefore this should be more or less a
straightforward copy. A quick sanity check of the file with ffprobe:

Stream #0:0(und): Video: h264 (Baseline) (avc1 / 0x31637661)
Stream #0:1(und): Audio: aac (mp4a / 0x6134706D)

So first of all, what I guess must be transmuxing via command line is
"ffmpeg -i 0.mp4 -vcodec copy -acodec copy 0.mkv". That gives me a
playable file -- VLC can read and play it, and my player can read it
(video plays back at least one frame and my implementation is hokey
anyway; audio plays back fine).

So I'm trying to transmux with libavformat / libavcodec. The code I
use to transmux appears last in this message. Encouragingly, on
opening the original file to transmux, I get these logs:

[mov,mp4,m4a,3gp,3g2,mj2 @ 0x212fa00] Format mov,mp4,m4a,3gp,3g2,mj2

I get those same logs for the command-line-transmuxed files, so no
obvious problem. And when transmuxing I get logs like these:

[matroska @ 0x20fbe00] Writing block at offset 15, size 7349, pts 0,

I get no warnings, no errors, etc. But the output file appears to be
mostly junk. ffprobe detects the video dimensions, the audio sample
rate, some scant codec stuff about h264 and aac...but generally
information is reported as n/a. If I try to play this file, VLC does
nothing and logs nothing. My own player appears not to be able to read
the header. Here are logs when I open the output file:

>From my own logs (not shown) I can tell it reads very far into the
file before reporting "Unknown NAL code", whereas on a good file it
seems that my player gets a lot of what it needs from the first <4k in
the file. As it is, this plays about 0.5 seconds of (correct) audio
and then stops decoding due to errors. No video frames are decoded.

So before I post the code, here are my questions:
- Do I have the right idea about transmuxing from mp4 to matroska?
- In the code you'll see that I do not ever call encode_video or
decode_video. Perhaps I must still call these, and trust that no
(expensive) reencoding occurs? How to I translate the "vcodec -copy"
semantics?
- Is there sample code or instructions on how to transmux with the
libs? My search results only mention command line.

And some last second details:
- Built the libs from ffmpeg 0.9.1 (harmony) with debug logging.
- Built with libx264.
- The code below has been stripped of most comments, error checking,
etc. I've already verified that no obvious error occurs. With the
exception of my transmuxing code, my code runs and works. In fact,
I've written code to encode in matroska format and then decode and
play back. This is based on that, but basically with the encode_video
and decode_video parts stripped out.
- The code below omits IO, file processing, callbacks etc. Nothing
interesting there (nothing ffmpeg-related).

Hi

I have an AVI file containing a screen recording.  The codec is TSCC.

How do I convert this into a file that I can playback using Windows Media
Player on Windows 7.  I don't have any audio - just video.

Thanks

barring that downloading ffdshow-tryouts might make it playable :)

You might get more support from the libav-user group.

Are you sure you're doing the equivalent of "vcodec copy" here?

Message-ID: <CAL1QdWefJBL6xyRvtBZXC79iJ1X0wtzPHhTnU0nWcgrcCD+NUA@mail.gmail.com>

Hello all.

I noticed that this works:

ffmpeg -i sintel.mpg -vf select="gt(scene\,0.4)",scale=160:120,tile
-frames:v 1 preview.png

(creates a single tiled frame with the first frame of each scene).

However, a user pointed out [1] that if you try and extract
"thumbnails" one per scene, using the same filter, it seems to create
"the normal number" of image files, but each is a duplicate of the
first frame in that scene:

$ ffmpeg -i sintel.mpg -vf select="gt(scene\,0.4)" preview%04d.png

Anybody know what I'm doing wrong here?

Thanks!

This is starting to become a FAQ: images do not have timestamp, so ffmpeg
duplicates them to accommodate the frame rate. You need to change the vsync
method to avoid that.

It looks like the same issue as https://ffmpeg.org/trac/ffmpeg/ticket/1644

Using -vsync vfr as stated in the first comment should help.

In general, I hate it when support people respond to a question with "why on 
earth would you want to do that" but I admit, it's hard not to think that way in 
this case; the codec is now 20 years old, and was useful only to create small 
videos that would play on a 1992 PC given the processing power available.

Perhaps if you told us what your overall purpose was, you might get a useful 
hint on how to achieve your objective in a reasonable way.

(P.S. I believe that Windows relies on codec DLLs being 'installed', but FFmpeg 
doesn't work that way; having a Cinepak (or any other) codec 'on your computer' 
is not going to enable FFmpeg to use it.)

Only the slower alternative prores encoder "prores_kostya" 
supports yuv444.

Hello Andy,

I wanted to benchmark this codec for comparing it with other codecs. 
Also I wanted to test this codec, because it seems to be one of the 
codecs which works without problems on mac and windows. The test 
sequences are low bitrate. I already found it on Virtual Dub.

Regards,
David

Fair enough. The other codec that you'll find wide support for / acceptance of, 
is the MPEG-2 stream found on DVDs.

His question was, even using prores_kostya with yuv444p10le, the
resultant file shows as yuv44p10le in ffmpeg, but in QT Player, it
says "yuv420p" when playing it.
So my question is...do any files say yuv422 when played in QT Player?

Apart from the fact that this is hard to believe, I was unable to 
find that claim in the original mail.

I am studying the source to see how command-line ffmpeg makes things
happen. Informative. I'll be trying things based on that. I'm still
wondering if there is more direct support for transmuxing...

Hi 
I want to stream a video file on my lan and get the stream on mms protocol.
like mms://192.168.100.10:8080
can anybody help me?

Subject: [FFmpeg-user] Benchmarking with ffmpeg - What are the parameters
	meaning?
Message-ID: <504C23C7.4080405@googlemail.com>

Hi,

I'm trying to compare some codecs. For encoding I use the -benchmark and 
-report. Afterwards I have a log file with some lines which confuse me....

frame=  136 fps=0.0 q=48.0 size=      21kB time=00:00:02.90 bitrate=

frame= 1000 fps=221 q=43.0 size=     197kB time=00:00:31.73 bitrate=  
50.9kbits/s
No more output streams to write to, finishing.
frame= 1065 fps=214 q=-1.0 Lsize=     238kB time=00:00:35.46 bitrate=  
55.0kbits/s
bench: utime=8.781s maxrss=49488kB

What is meant by the fps? Is it the (averaged) speed at which the frames 
are processed? So 1065frames / 214fps = 4,97 s. Which is not equal utime 
= 8,7818s. Also I have seen that at the end time=00:00:35.46 is exactly 
the length of the encoded video. Could someone please explain me the 
parameters?

BTW exists there a mode for benchmarking the DEcoding process, so that I 
have some stats and won't need to play all the files in realtime?

Regards,
David

No, not averaged but current.

That is correct and this should be very accurate.

If you mean frame, size and bitrate, I assumed they are 
self-explanatory...
(I suspect bitrate is also current, not average, but I 
did not test.)
utime is the time spent on CPU, maxrss should be 
maximum memory footprint.

I always use:
$ time ffmpeg -i input -f null -

Subject: [FFmpeg-user] Problem with libfdk-aac and VBR quality option
	"quality out of range"
Message-ID: <CAKYWZ4dV=9g6-KOPPh1x3nPxV16mVzeS3ui-xxj_pjPe5YK=8Q@mail.gmail.com>

Hi guys,
first off, there are so many aac encoders (faac, visual on, fdk-aac,
builtin aac, ...). Does someone know where I can read more about the
features so I can choose which is the best for me?

I used to use libfaac but I read that the implementation is considered 'bad
quality' and that fdk-aac is considered 'good quality'. So I built ffmpeg
with libfdk-aac support but there is a problem with using -q:a option to
set VBR quality. -b:a works fine but will produce a quite static bitrate, I
want to use a variable bitrate.

libfdk-aac supports a quality range of 1-5:

VBR quality X out of range, should be 1-5


However setting -q:a to 1 to 5 will produce an error:  [libfdk_aac @
0000000003da2b60] VBR quality 118 out of range, should be 1-5

I believe a value of 1 can not be used in VBR mode. See:

Subject: [FFmpeg-user] How to find the last working GIT version?
Message-ID: <504BDC95.5060804@gmail.com>

Hello all,

I've got a problem with FFmpeg remuxing MKV to MPEG-TS (video mux, audio 
recode or drop, doesn't matter) and I have the last working build from 
around N-43161-g31d8261. Shortly after (a few days or a couple of week 
at most) that it stopped muxing properly. What I mean by that is that 
video freezes a few seconds into certain videos (not all) and then skips 
further to another frozen frame and so on.

I'd like to try and narrow it down by getting each consecutive day after 
that last-known working build and building to see when it starts to 
break. Can you please supply a git command line to do that?

Also, how can I look at changes between two builds (in source) to see if 
I can spot it myself?

Which files should I concentrate on comparing?

Thanks!

    Dennis

Can you please supply a git command line to do that?

Look into using git bisect. It'll do a binary search on the commits between
a known working version and a known broken version, and narrow it down
until you can find the commit that caused the break. Google should be able
to find plenty of examples for git bisect. I think there might be a tool
even in ffmpeg/tools to help with bisecting too, though I've never used it.

Sorry I can't give a proper command off the top of my head; I'm replying
from my phone so please excuse any spelling or grammar errors.

Do you know what files I should concentrate on?

Message-ID: <1347253362600-4653305.post@n4.nabble.com>

Hi,

I have a licensing question.

I make a change in a FFmpeg source file and call a function from a
dynamically linked external library (libmyext). I configure FFmpeg without
"enable-gpl" and without "enable-nonfree". The only way the modified code
will be invoked is if FFmpeg is configured with --enable-myext. I update my
EULA as mentioned in the Checklist at http://ffmpeg.org/legal.html and I
make the source code for the updated FFmpeg available on my website. 

Can I include FFmpeg in my product distribution? 

Is it ok for me to choose a proprietary license for that external library
"libmyext"? Or am I required to make it an open source GPL/LGPL based
license? 

Can someone please advise.

Thanks.

Command line and complete, uncut console output missing.
(We are very interested in such bug reports and while I 
appreciate it if you do the bisecting, you may not have 
enough time to do it and I will probably be faster.)
A sample might be needed too.

Do not concentrate on files, git bisect will tell you 
the responsible change.

Make sure you follow all license terms of the LGPL or 
follow http://ffmpeg.org/legal.html
(ianal, but you can link whatever you want against LGPL'd 
FFmpeg but you must not forbid reverse-engineering the result.)

I appreciate that and I'm sure you'll spot the problem much faster.

I didn't provide the command-line as it seems to not change the end 
result (and I've tried lots of variations with audio on/off and various 
audio codecs, but always remuxing video). I can provide a sample, but I 
need to somehow cut the original file (it's over 4GBs).

I can submit a formal bug report about this with the command-line and 
sample. What size (in MBs) should I cut it down to -  is 50 MBs ok (the 
first problem spot comes at around 40 seconds, which is around 20 MBs 
remuxed)?

Command line and complete, uncut console output are needed 
for every report, both here and on the bug tracker.

Only you can answer how big the needed sample is, the only 
important thing is that the problem has to be reproducible.

Either post all necessary information here or read 
http://ffmpeg.org/bugreports.html (ignore the size limit).

Ok, I'll experiment with the sample size to make sure it's reproducible 
and upload/submit a bug report about this and then post back here.

I was mostly asking about the sample size to make sure your ftp has 
space - heck, I can upload the whole file :) If there are no limits, 
that's fine, I'll find a small enough reproducible sample and upload 
that (probably no more than 50 MBs or so).

Ok, I've submitted a bug report: 
https://ffmpeg.org/trac/ffmpeg/ticket/1724 and also now uploading a 
sample "remux_frozen_video_sample.mkv" to the ftp (it should be done in 
6 minutes).

Roger may be "intermingling" knowledge of a thread on ffmpeg zeranoe 
(http://ffmpeg.zeranoe.com/forum/viewtopic.php?f=7&t=707&sid=3274fe1a5efcc0021653f967447f9057) 
and this thread but he is correct.
It may be hard to believe but every quicktime that I have tried to 
convert in ffmpeg using yuv444p10le and prores or prores_kostya results 
in a prores quicktime that ffmpeg indentifies as 444 yet is identified 
as 422 by quicktime player.

Carl is the first person to suggest that ffmpeg cannot create yuv444 
(which helps the mystery a bit).

I tried very hard to suggest that FFmpeg is able to create 
yuv444 ProRes files.
Please provide your failing prores_kostya command line 
together with complete, uncut console output.

It does not set the correct fourcc. It should be ap4h but it is apcn
(which is the fourcc for prores 422). Quicktime and other apple
software (like Final Cut) more or less blindly trust the fourcc. I
tried overriding it with -vtag but that didn't work either:

Hopefully it works out for you.

useful as well.

Definitely averaged..... I often skip a few minutes of streams when
recoding and the value slowly climbs - starting at 0.

Actually I had a thought the other day that it would be nice to
display both "recent" fps and "average" fps on the command line...I
know I would benefit :)

It is missing the part where you explain how I can reproduce 
the problem, the remuxed file plays fine here.
Or is this really a Bravia-only problem?
In this case you will have to bisect yourself...
(But I will help you with a configure line if you confirm 
that I cannot reproduce the problem.)

It is absolutely possible that I completely misunderstand 
how pkg-config is supposed to work, but imo 
pkg-config --libs should allow you to link to the library 
no matter how you configured it (or in other words: the 
pkg-config file of fontconfig has to look differently 
depending on how you configured fontconfig).

I couldn't find much information about theses parameters. Can you tell

What benefit do I have from knowing maximum memory footprint? It doesn't 
seem much informative.

Can you tell me why this means that it is the average speed and not the 
real speed at which the frames are processed. I'm not sure if I 
understand the assumption in your example.

Imagine you're doing a screencast for 2 hours using ffmpeg.  After 5
minutes, the fps cuts "in half" because of up-network traffic
congestion.  The ffmpeg console output wouldn't really let you know
that you're now operating "at half speed" until much later.  The other
example is if cpu congestion occurs when you're half way through
transcoding a file, you might not know about it for quite awhile (or
if you're receiving from stdin and it blocks for a minute, then
continues, your fps will be abnormally low).  Those types of
situations.

If I skip 5 minutes of video at the start of an encode (with -ss
0:05:00) the processor is searching for the I frame closest to 5mins in.
I think it does this by decoding the stream as fast as it can - lets say
it takes 1 minute to reach there.

During this 1 minute, the fps = 0, after 1 minute, the fps gradually
climbs and heads asymptotically (with a little under/overshoot) to the
final fps value. I.e. after it has encoded 10 secs of video, fps may be
4. After 10 minutes of encoding, it may have settled to 30fps.

If it were measuring "current" encode rate, it would immediately jump to
30fps as soon as it starts encoding.

I think the maths is simple number-encoded-frames/secs-since-start. That
is, after all, the definition of fps for encode rate (you encode 100000
frames - it takes you 10000 secs, fps = 10).

ok, if you have the drop with a delay then I would agree.

Well, VLC does play it fine, so it may be related to hardware-based 
player which are obviously a bit more limited and perhaps strict.

If you can give any further hints on doing the bisect, I'm happy to 
spend a few hours on it.

What about the configure line - should I enable debugging to get more 
information?

What I need to do is set up two new folders from git - one for the 
version I know works and another for a version 2 weeks in advance (as I 
believe that's roughly the time-frame when it broke) - I don't know how 
to do that. I can then do bisect on that and see what I can come up 
with. I've got a reproducible environment here, so it may be easier for 
me after all.

Thanks,

    Dennis

Ok, now I don't know what current encode rate could be? The momentary 
output?

In the beginning I have some lines like that.

frame=  113 fps=0.0 q=39.0 size=      40kB time=00:00:02.13 bitrate= 
154.1kbits/s

Is this 0 because also 0 seconds have passed? And the calculation in the 
first second would be 113/0 ?

Is this a valuable method? The first time I do this the process last 
about 3 seconds and I get u time=0.062s and maxrss=8740.
The second, third,fourth..... time I repeat the encode it doesn't even 
needs a second to encode but I get values similar values like in the 
first round and maxrss is the same, only very small differences.
So I changed the name of my input file. Then again one run 3 seconds and 
the next  again very fast....

So it seems that the video is in the memory after the first run.

For comparing I would need to do a first run with the input video and 
then gather the times. But I don't know if with this speed you can 
measure exact enough for comparison.

And I'm searching especially something for decoding. Is there an option 
for only measuring the decoding performance?

What is the full command line you have here?

That tells me the following information:

frame = 113. ffmpeg has encoded 113 frames.
fps=0.0. You don't look like you are encoding video at the moment- this
is confusing.
q=39. A measure of quality. I'm never sure what that means to be honest
size= The size of the encoded video data so far.
time= how long the encoded data is if you'd play it back
bitrate= average encoded bitrate (size/time).

The reports here are entirely consistent - but yours don't look it. If
I'm not encoding fps=0, as soon as I start actual encoding (as opposed
to searching) fps starts to increase.

It is unlikely to provide anything directly. ffmpeg is a transcoder, it
isn't a player. It also depends what you mean by "measuring the decode
performance" (actual CPU used, elapsed time...).

You could probably estimate decode performance by using -ss to skip to
the end of the file. As far as I know, ffmpeg skips by actually decoding
the video, so skipping to the end of the file means the program has to
decode the whole file.

Hi,

I'm searching for variable bitrate mode when using libvpx with ffmpeg. 
Only found qscale <1 - 31> but it makes no difference which value I use. 
It seems always to use 200kb/s. Is there any vbr mode?

I don't get it working properly.... I use this command :
ffmpeg.exe -i "C:\original.avi -c:v libvpx -quality good -crf 50  -qmin 
2 -qmax 63  -v:b 200 "C:\coded.webm"
It sets the bitrate all the time to 200...
Also if I change in my commnad line the crf to something lesser than 4 I 
get error that crf has to be smaller than qmin.

This some of the output I get in the beginning of the encoding process:

[libvpx @ 024afc00] rate control settings
   rc_dropframe_thresh:          0
   rc_resize_allowed:            0
   rc_resize_up_thresh:          60
   rc_resize_down_thresh:        30
   rc_end_usage:                 2
   rc_twopass_stats_in:          00000000(0)
   rc_target_bitrate:            200
[libvpx @ 024afc00] quantizer settings
   rc_min_quantizer:             4
   rc_max_quantizer:             63

Can some one please provide me with some working VBR command line in 
which I can set the quality?

Thank you,
David

This is expected behaviour since you explicitly tell ffmpeg 
to encode with a video bitrate of 200

For your next report, please do not forget to paste complete, 
uncut console output.

The first step is to sanitize your command line.
Does the following allow to reproduce your problem 
(ie does it still work with the older FFmpeg version 
and succeed with the newer one)?
$ ffmpeg -i remux_frozen_video_sample.mkv -vcodec copy 
-ab 640k -acodec ac3 out.mts

Sorry, I wasn't paying attention and made this mistake. I changed the 
number before sending it.
The mistake was that I used 'v:b' and not 'vb'. The console ouput was 
huge, but it encoded and used the generic setting for the bitrate. But 
whart I could not change was that I could set my 'crf' lower than the 
generic minimum quantizer which is 4. But I don't mind anymore. It's ok 
if I can set the 'crf' and the bitrate.

Message-ID: <tencent_35CD2FE97026A21F0D3AF838@qq.com>

Hi All,
 I want to use FFmpeg decode libraries to decode an h.264 video stream. I found the libavcodec/api-example.c is a test example can decode MPEG1VIDEO format video streams. Now I use CODEC_ID_H264 instead of CODEC_ID_MPEG1VIDEO and build it, then add an argument (h.264 encode video stream) when ran the test case, there an error occurs. Below is the error log:
  
 #Video decoding
#[h264 @ 0x8937020]error while decoding MB 14 7, bytestream (-23)
#[h264 @ 0x8937020]concealing 955 DC, 955 AC, 955 MV errors
#[h264 @ 0x8937020]no frame!
#Error while decoding frame 0
  
 Who can help me to resolve this issue?
Any feedback is appreciated.

Xin

Yes, same behaviour.

Actually, I can't convert without the h264_mp4toannexb filter as FFmpeg 
doesn't let me, but the rest of the command line is as you've asked for. 
Furthermore, I can replace "-ab 640k -acodec ac3" with "-an" and it 
still breaks in the same way, if that makes things easier.

So, just "ffmpeg -i remux_frozen_video_sample.mkv -vcodec copy -bsf 
h264_mp4toannexb -an out.mts".

It isn't quite clear to me exactly what time lapse you want to measure. If
it's for the whole ffmpeg pass from start to finish, I use the below on
Windows. %INPUT% and %OUTPUT% are set to the input and output filenames
respectively. %PASS% is obviously set to the pass. My script actually uses a
single command line for both passes, appropriately adjusted for each. So the
first time execution passes through here %PASS% is set to 1 and the 2nd time
to 2.

Hopefully this is of some help.

echo Start %INPUT% >%OUTPUT%.time.txt

echo Start pass %PASS% >>%OUTPUT%.time.txt
echo. | date | find /v "Enter the new date: (yy-mm-dd)" >>%OUTPUT%.time.txt
echo. | time | find /v "Enter the new time:" >>%OUTPUT%.time.txt

ffmpeg ... -pass %PASS% ...

echo End pass %PASS% >>%OUTPUT%.time.txt
echo. | date | find /v "Enter the new date: (yy-mm-dd)" >>%OUTPUT%.time.txt
echo. | time | find /v "Enter the new time:" >>%OUTPUT%.time.txt

Sorry for the mistake.

To speed this up, I did the bisect;-)
Could you confirm that 2107009 (git checkout 2107009) works 
fine and that 3e1cf49 is failing?

looking at the code, it looks as if Prores 4444 is not modeled as a
profile at all (see variable prores_profile_info), so it never sets
the correct fourcc.

" The third is FFmpeg's native AAC encoder (considered experimental by the
developers as of December 2012)"

In case that's a typo, I just thought you'd like to know.

Subject: [FFmpeg-user] converting to non HD avi with ffmpeg
Message-ID: <CAGXs5wWJsFyH_LAC-5F32YtZFNVJ-nwKDKAxYGgaoYruPg5G6A@mail.gmail.com>

Hi,
I have downloaded from the web a video file with webm extension:
ubunutuArm.webm (some lecture in video)

Now, I converted it to avi thus:
ffmpeg -i ubunutuArm.webm ubunutuArm.avi

and put the ubunutuArm.avi on disk On Key.
When trying to view it on TV with a DVD I see this
messsage:
"HD is not supported".
Indeed, HD is not supported in my DVD and TV.
Is there a way I can convert this video file with ffmpeg
to an AVI so the result will be non HD ?

(Second question: given some avi file, is there a way
I can know whether it is in HD or not ?)

Regards,
Kevin

change width/height and bitrate
you did not set ANY parameter

Thank you for your script. Can you tell me how I can start it with 
arguments. I don't know the syntax. I tried to give it arguments but it 
doesn't takes them. How can I set e.g. %OUTPUT% from command line? And 
what means 'Start pass' (not %Pass%)?

I tried it with replacing with setting the variables in the script..... 
and it shows me time, but only hh:mm:ss.

Reindl,

Thanks a lot for you quick response!

> change width/height and bitrate

excuse me my ignorance: which  width/height and bitrate
are needed for non HD ?

Hey,

I don't have the time and the knowledge to for doing that. Is there

My hard-coded DVD MPEG-2 script (called ffmpegencode.bat) is called with
parameters on the command line e.g.:
ffmpegencode input.avi 6090000 input.ass

where in this case input.avi is the input file, 6090000 is the requested
bitrate and input.ass is a subtitle file.

Command line parameters in Windows and DOS are identified inside the script
as %1, %2 etc. Up to a maximum of 10 I think, then you have to use the
'shift' command.

The script sets other values such as %OUTPUT% internally. Here is the full
script (ffmpeg command not yet updated for presets etc.). Hopefully this
will give you some idea of how the script uses command line parameters as
well as the time-stamping commands.

This may not work as is for you esp. when specifying subtitles, in which
case the script uses Avisynth to inlay them. If you set the external
environment variable FFMPDBUG to 'echo' before calling the script, i.e.
set FFMPDBUG=echo

the script prints what it would have done and exits.

Start pass %PASS% writes to the text file 'Start pass 1' or 'Start pass 2'
(depending on value of %PASS%), to distinguish the timestamps of the two
passes.

Mine shows "13:54:30.37". I can't be certain but the format is probably
specified in your computer's date and time settings.

Here's one place to start:

videohelp.com also has a usable glossary and informative forum for general

I always use:
$ time ffmpeg -i input -f null -

(You are right that this does not only decode, it also 
encodes to the "null" format, but I don't think this 
will affect the measuring.)

And this of course does not make sense if the whole 
transcoding process takes less than 0.1 seconds.

It's not meant in the sense that I wouldn't do it if I had the time. 
Also I tried to find long enough finding a solution. I don't know why 
someone with with not that much experience should do that if someone 
more experienced user with the program could help and save hours of 
frustration?
I wanted to use ffmpeg for my programm but this really seems too much 
work. So if someone who knows the parameters could help I would be very 
glad.

Yep, you've nailed it :) Thank you for helping out and yes, it's like 
that - 2107009 works, 3e1cf49 doesn't.

What do we do next? :)

We wait until somebody who has knowledge about muxing 
transport streams looks into the ticket you opened.

If you believe that encoding to the null format affects 
the decoding performance measurement, I honestly wonder 
how you are going to measure encoding performance 
without using a decoder.

Please put (and leave) an empty line between quoted text 
and your reply, it makes reading mails significantly easier.

Ok, that makes sense, but is there a way to find out, now that we know 
the broken build, all the changes and see what could've caused it?

I'm happy to try and revert changes one by one (if there are not 
hundreds of them of course) till I find the one causing this. I just 
need to know how to find out which files changed between two commits 
(and it would be great if you or someone could point me to files that I 
should concentrate on).

Do you mean "git log -p 3e1cf49" ?

Yes, thanks, but that's overwhelming :) Ok, I guess we'll wait, or, if I 
could find out which files are involved in muxing, I could still go 
ahead and try to revert things.

In any case, I'm glad that at least the problem is identified - thanks 
again.

Ok. I could first transcode my uncompressed files and then I could 
decode and "encode" the target format to null to see the target formats 
behaviour. But probably I would need to free the memory after each test.

	FWIW, those are the same revisions where I got my bug too (the one about capturing 
MP4 streams from an Axis camera). I never got to open a ticket, though; I'll see if I can do so 
tomorrow...

I'd guess it would start like

$ ffplay -i mmsh://istreampl-classicstation-live.wm.llnwd.net/istreampl_classicstation_live

Oddly, the original url as mms:// so i had to add an h.  Maybe ffmpeg
should be modified to accept mms:// type url's?
Thanks!

My guess is to pass it some size parameter, like -vf scale=100x100

I think.

Subject: [FFmpeg-user] grayscale video streaming in ffmpeg
Message-ID: <CADf17_YirPq-ZXB=oAf9MXUNmBdvLWs_FqhFTC0E2qWQzBvUNg@mail.gmail.com>

I have a raw video file (testvideo_1000f.raw) that I am trying to
stream in gray scale using ffmpeg and output the grayscale video to
output.swf. The command I am using to do this is:

ffmpeg/ffmpeg -qmin 2 -qmax 31 -s 320x240 -f rawvideo -flags gray
-pix_fmt:output gray -an -i testvideo_1000f.raw output.swf

However, the result from this command is a video stream that is in
gray scale but still contains some of the chrominance data. The output
from this command is pasted below:

I am fairly new to FFMPEG and I am afraid I am using either the wrong
syntax or the wrong parameters in my command line. For some reason,
the format of the output is yuv420p. I have tried searching for this
answer all over but have had no luck.  I should also note that I am
trying to get a grayscale video by completely deleting the chrominance
information, not by just zeroing it out. I want to transmit only the
luminance data.  When I give the '-pix_fmt gray' parameter, I am
seeing the shortened buffer length I would expect from all of the
chrominance information being deleted but the output video still
contains some of the chrominance data.

Could anyone please help me and tell me why the output is being
formatted in yuv420p when I am giving the command for it to be in 8bit
grayscale?

Any help would be greatly appreciated. Thank you.

ffmpeg -i input -filter:v scale=640:-1 -q:v 3 output

I added the scale filter which will create an output that is 640 pixels
wide and the height will be automatically calculated to preserve the
aspect ratio. Of course you can change 640 to whatever desired width
you want. You can also switch the position of the -1 and provide a
desired height.

The other addition controls the output quality to something probably
better than the default of "-b:v 200k".

You can see the size of a video stream with the output of:
ffmpeg -i input

The default video codec for swf is flv1 (Sorenson Video) and 
this codec only support yuv420p. You can try -vcodec mjpeg but 
this seems to have problems (I don't know if they are expected).

You do realize that you only have to change one line to

What I meant is to find the actual source code change that caused this. 
To do that, I'd need to know which files are potentially involved and 
look at difference in those files, because if I look at all the 
differences, there are just too many of them :)

git log -p 3e1cf49 shows you the change in commit 3e1cf49 
(a version that you know is bad) and all prior commits, the 
first commit before 3e1cf49 is 2107009 that as you know is a 
good version, so you only have to revert the one line from 
commit 3e1cf49 but none of the (several ten-thousand) 
earlier commits.

I hope this clears it up, if not, try to remove 
"&& has_decode_delay_been_guessed(st)" from 
compute_pkt_fields() in libavformat/utils.c

Ah, ok. I was confused by the huge amount of output of that git log 
command. I'll need to study it closer to see how you found that 
offending line in the first place.

Thank you for the hint - I'll try and remove that and see if it makes a 
difference (I guess it does, since that's the offending line).

Message-ID: <CAN=EPpnrEKS4yU=qkZTT31x1z4PTs2Umf-5H0Oo2Qm0Hfkrh-w@mail.gmail.com>

Hi All,

Does FFMPEG support the latest streaming technique MPEG DASH? I know it
produces HLS compatible TS segments. But I would like to know if it can
produce DASH MPD files and segmentation and muxing?

Do I have transcode using FFMPEG and use GPAC to create DASH segments?

Thanks,
Geetha

No, my next step would have been to correct the fourcc and see if
Final Cut behaves correctly. Other than that, I would not know what to
look for. Pixel format seems to be OK, as it is detected correctly by
ffmpeg when running it on the resulting file. I can try a hack to get
the correct fourcc in there and check the above.

Thank you for analyzing this - I simply didn't understand the problem;-)
(I couldn't believe it was not reported before and not tested originally.)
Could you test attached patch? It contains some guessing.

Thank you, Carl Eugen

I'll test the patch immediately. Just a quick update: I hacked the
codec not to override the fourcc if it is set on the command line and
the result was detected as Prores 4444 bei Quicktime but the alpha
information was lost. I verified by making a clip with alpha,
exporting it via final cut as prores 4444 and using the resulting clip
in a final cut sequence as an overlay, which worked. Then I transcoded
the exported clip using ffmpeg into 4444 using the hack and used that
clip as an overlay and alpha was gone. If a one-frame-sample of prores
4444 with alpha would help, I can make a trac issue and attach it.

I'll post the results of testing your patch next.

Regards,

Robert

I don't know if I am doing anything wrong but the patch does not apply
to a clean git head here, although the patch file looks ok (not
mangled by mail client):

Ok, just to confirm - I've built latest head with that removed and it 
works fine, so that is the problem spot there.

The encoder currently does not support alpha...

... which is related to the fact that the decoder does not 
support it because afaik we don't have a sample.

Please provide a sample, Carl Eugen

The sample I have is one frame long and 220k in size. How do you want
me to give it to you?

OK, thanks.

Patch works. The resulting file looks good and is recognized by
Quicktime as Prores 4444. Thanks!

Hello,

I'm trying to record some gameplay using ffmpeg. The game itself works
flawlessly but captured video has tearing in it. I have VSync turned on in
nvidia-settings and when it's turned off there and in game I can see
tearing in game, too. Is it me doing something wrong or does ffmpeg lack
some syncing capabilities? You can see command I used to record and libs
versions on this video:
https://docs.google.com/uc?export=download&confirm=no_antivirus&id=0BzijM0VPyPPQUnNELWhwcm55SFU

I used ALSA snd-aloop module to record audio.

If you don't want to send it to this list (or via pm) 
and don't want to open a ticket yourself (I will do it),
please upload as explained on http://ffmpeg.org/bugreports.html

Please also add the sample as rgba png, so the developers 
know what it should look like.

Thank you, Carl Eugen

I fixed muxing mjpeg in swf, but that does not help with your 
original problem: There is no video codec supported in swf 
that allows to encode gray - you can only set u and v to the 
appropriate values.

Subject: [FFmpeg-user] split and re-encode H.264 stream at IDR frame
Message-ID: <CAKYWZ4c9CCpsNq1RHNOJBTqGqx_KE+x_MVmwhnaZwbhicX9DSQ@mail.gmail.com>

Hey,
thanks for your help with my other questions, you were really helpful :).
I got another question: I got a blu-ray disc with 2 episodes of a show in
one m2ts file. Both episodes share the same H.264 and PCM streams and the
second one is selectable from BD menu.
I want to re-encode the episodes to H.264 (with less bitrate) and flac. The
problem is to split the clip as the episodes don't have the same length.
At the point where the second episode starts there is a IDR frame in the
H.264 stream and I want ffmpeg to split exactly before that frame.

The blu-ray menu says that the second episode starts at 00:23:42.046. I
used Avidemux to look where the IDR/I frame is. Avidemux says that the IDR
frame is at 00:23:42.088 and the frame prior to that is at 00:23:42.047.
Well the times of Avidemux and the BD menu don't match, I guess Avidemux is
reading the file incorrectly.
I used FFprobe to dump frame information and this is what I got:

The frame ahead of the IDR frame:

[FRAME]
media_type=video
key_frame=0
pkt_pts=1422046
pkt_pts_time=0:23:42.046000
pkt_dts=1422046
pkt_dts_time=0:23:42.046000
pkt_duration=41
pkt_duration_time=0:00:00.041000
pkt_pos=5828419424
width=1920
height=1080
pix_fmt=yuv420p
sample_aspect_ratio=1:1
pict_type=P
coded_picture_number=34094
display_picture_number=0
interlaced_frame=0
top_field_first=0
repeat_pict=0
reference=0
[/FRAME]


And the IDR frame itself:

[FRAME]
media_type=video
key_frame=1
pkt_pts=1422087
pkt_pts_time=0:23:42.087000
pkt_dts=1422087
pkt_dts_time=0:23:42.087000
pkt_duration=41
pkt_duration_time=0:00:00.041000
pkt_pos=5828419597
width=1920
height=1080
pix_fmt=yuv420p
sample_aspect_ratio=1:1
pict_type=I
coded_picture_number=34095
display_picture_number=0
interlaced_frame=0
top_field_first=0
repeat_pict=0
reference=3
[/FRAME]


The times match with the BD menu however if pkt_dts_time is the time where
the frame *starts* then it would be off by 1 frame (the bd menu would refer
to the last frame of the first episode instead of the first frame of the
second episode).
However this is FFprobe's output for the FIRST frame of the whole file:

[FRAME]
media_type=video
key_frame=1
pkt_pts=42
pkt_pts_time=0:00:00.042000
pkt_dts=42
pkt_dts_time=0:00:00.042000
pkt_duration=N/A
pkt_duration_time=N/A
pkt_pos=799
width=1920
height=1080
pix_fmt=yuv420p
sample_aspect_ratio=1:1
pict_type=I
coded_picture_number=0
display_picture_number=0
interlaced_frame=0
top_field_first=0
repeat_pict=0
reference=3
[/FRAME]

pkt_pts_time is not 0 what I would expect for the first frame of a video to
be so I assume it's the time when the frame is *over* and not where it
*starts*? Please correct me if I'm wrong, I'm completely unsure here.

So all in all, if I want to create two videos from this file I need to use
these commands?

ffmpeg -i INPUT -c:v libx264 -c:a flac ... -t 0:23:42.087 OUTPUT #first
episode or maybe 0:23:42.046 which is the pkt_dts_time of the *second last*
frame which means the time where the *last* frame starts if I'm correct.

ffmpeg -ss 0:23:42.087 -i INPUT -c:v libx264 -c:a flac ... OUTPUT #second
episode, first frame of the second episode if I'm correct, also the same
time the BD menu entry suggests.


Or is there perhaps a much easier way to split at the IDR frame? I couldn't
find out if I can tell ffmpeg a frame count where it should end or start.
Don't know if that would work either because I get a "[h264 @
00000000015a2800] number of reference frames (0+3) exceeds max (2; probably
corrupt input), discarding one" while decoding and that could bring the
whole thing out of sync maybe.

Sorry for such a long post again.

Ok, I get what you're saying.  I don't have to use .swf.  I can use
any type of video output.  How do you take advantaget of the -pix_fmt
flag in ffmpeg in order to specify the pixel formats GRAY8, GRAY16LE,
and GRAY16BE?  There has to be someway to implement these commands,
right?

Thanks again for your input.

I'm not an "expert" but I'm hoping that if I start with the parameters I 
understand, people will add or correct any I miss.

Many of the lines in this are irrelevant. They are formalities such as "Name", 
or they're defining things as not applying in this case, such as QPel (false). 
Yet others simply control the way the coder works, e.g. Turbo (false). Yet 
others are options; only one FourCC can be in any file, and the XML gives four! 
Even further, some options are plainly silly: if interlacing is "false" then we 
don't need to know that "bottom field first" is "true" - LOL


I will translate the options that I think you actually need:

If you want two pass encoding then you should read up about it; basically you do 
it twice, first with "-pass 1" then with "-pass 2" but it's ONLY relevant if 
you're trying to squeeze into a certain size (e.g. fit on a CD).

The other options that I generally use for XVID are
-mbd rd -flags +mv4+aic -cmp 2 -subcmp 2
and also
-vb 1500k
which sets the bitrate.

Hope this helps. What about audio?

	I can confirm that it also solves the bug I found, the one where dumping an H264 
stream from an Axis camera gave an "mp4 @ 0xaa897a0] pts (0) < dts (1) in stream 0

You should be able to split at it using "-ss" see
http://ffmpeg.org/trac/ffmpeg/wiki/Seeking%20with%20FFmpeg

Since you're re-encoding you should be able to jump anywhere you want...

Yeah Avidemux assumes constant frame rate, I know this is wrong for at
least some mpeg streams, dunno if it's the same problem you're seeing.
 It's what taught me not to trust it, anyway :)

pts is when it starts.  Maybe it's a blu-ray thing to not start
precisely at second 0 to give it time to get going...

the select filter has an "n" option if that helps (I kind of doubt it
would do what you're looking for though...)

What's your complete output? Do you get this no matter what command you use?

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

If anybody's up to it, I got a request for libopus as an encoder, and,
since it's mostly been released now it might be nice.

	Oops, sorry. The output I posted wasn't from the latest version (this is what happens 
for not knowing how to use git). However, now I've updated to the latest version (for real) and 
I can confirm that the same thing happens: it doesn't work, but if I remove the above part of 
the code, it starts working.
	Below is the output (of the version with the modified code). Do you guys need me to 
open a ticket and add there all the information related to this bug?

Download is 140 MB. Can you provide the ffmpeg command and the complete

I have it in my TODO list, but less free time than two weeks ago.

If anyone wants to work on it, do not hesitate, but please let me know to
avoid duplicated efforts.

The tiff, png, sgi, jpegls, pam and libopenjpeg encoders 
support both gray and gray16, you can also use ffv1 if 
you also receive with FFmpeg.
(Some more encoders - qtrle - support gray but not gray16.)

Sorry, this video is really too big to just show the problem. Here's the
command I used:

ffmpeg -f x11grab -s 1920x1200 -r 30 -i :0.0 -f alsa -i loop -vcodec
libx264 -preset ultrafast -acodec libfaac -ac 2 -ar 48000 video.mp4

The output was quite big and I can't repeat the recording right now. I've
cut the video to first ten seconds (5.6 Mb) where tearing is quite visible
on framestep viewing:
http://rghost.net/private/40334000/f3835aac094ca2292efcc658bf49511b<http://rghost.ru/private/40334000/f3835aac094ca2292efcc658bf49511b>

I don't claim it's a bug in ffmpeg, I'm just curios if I'm the only one who
get this. Linux gaming isn't a usual thing so screen capturing is often
limited to screencasts with mostly static background and text.

I read about troubles with vsync in NVIDIA's blob and some issues in Wine
but it's really hard to notice tearing on 60 FPS. When vsync is turned off
FPS is quite high which makes tearing visible very well but when FPS is
equal to the refresh rate (even if vsync doesn't work or broken) then
there's only one tear possible if I understand it correctly.

Hi All,

Does FFMPEG support the latest streaming technique MPEG DASH? I know it
produces HLS compatible TS segments. But I would like to know if it can
produce DASH MPD files and segmentation and muxing?

Do I have transcode using FFMPEG and use GPAC to create DASH segments?

Thanks,
Geetha

Hi, Lou.

Thanks!

I have tried:
 ffmpeg -i ubunutuArm.webm  -filter:v scale=640:-1 -q:v 3 ubunutuArmNonHD.avi

And when loading the avi in a DVD I still get the HD error.

I tried to fetch the avi properties, and this is what I got:


ffmpeg -i ubunutuArmNonHD.avi

So any idea:

2)  what should I do to create non HD avi ?

Thank you very much. Unfortunately  I  now used the command line utility 
XvidEncraw which took me 5 minutes, as it has almost all of the 
parameters as default settings and his paramterlist as a xvid only 
encoder gives it a high usability mark. But perhaps I will  integrate it 
into my program if I have the time. Perhaps it makes sense so see which 
are the default parameters set by ffmpeg. Do you know  how I can read 
out the default parameters of an ffmpeg encoder so I can see which 
parameter I need to change and which not?

Your output is 640x360. This can be considered standard definition or
"not HD".

It is not HD. ffmpeg will show output size in the console output. Look
above to see my awesome ASCII art arrow for an example.

> 2)  what should I do to create non HD avi ?

You already created a non HD file; therefore we need to determine what
the actual issue with the player is. Do you have a video that does play
on this picky device? If yes, then show the complete output of "ffmpeg
-i input-file-that-actually-does-work-in-your-dvd-player.avi".

I have made a DVD file in the past, can you try this? However, I notice that 
some syntax has changed in the last months, forgive me if some of these 
parameters need their syntax updating...

ffmpeg -i ubunutuArm.webm -target ntsc-dvd -bf 2 -flags2 ivlc -dc 10 -b 8000000 
-maxrate 9000000 -bufsize 224kB -acodec mp2 -ac 2 -ab 128000 -vf scale=720:480

I don't know how to answer that; I know that FFmpeg will choose sensible 
defaults wherever possible and/or will mimic the input file where relevant; 
hence, it frequently "just works". If you use a 'preset' then these preset files 
(extension .ffpreset) are human-readable.

I did have trouble making a XVID file for a DVD player I have that claims to be 
able to play DivX; the command I finally used was:
c:\ffmpeg\bin\ffmpeg -i blch-01.mkv -sn -c:a libmp3lame -ar 48000 -ab 128k -ac 2 
-c:v libxvid -crf 24 -vtag DIVX -vf scale=640:480 -aspect 4:3 -mbd rd -flags 
+mv4+aic -trellis 2 -cmp 2 -subcmp 2 -g 30 -vb 1500k -y blch-01.avi

(It was important to me to erase the subtitle stream because I couldn't turn the 
darn thing off!)

I suggest that copying this form should work for you (nuke the windows path of 
course, if on Linux) since I believe my rather old DVD player is rather fussy, 
and several of these files worked.

Good luck.

Hi,
I have few doubts regarding utime in ffmpeg.

Suppose i am running ffmpeg vp8 decoder on multicore processors(like
pandaboard with ubuntu image).

If there are two threads running parallely on both cores. The final
transcode time is utime :: 25000000 us.

Is process time added for both cores(ie, both threads) ?

what is the final execution time(should i halve the process time) ?



Regards,
hitesh

Hi,

Three quesiton:
1, Is there a video or audio file can't be seekable and can't get it's
duration?
2, Is there a video or audio file can be seekable but we can't get it's
duration ? 
3, Is there a video or audio file we can get it's duration but can't be

It's could be better if you can tell me more detail about the questions.

Thanks.

Where are you getting "final transcode" time from?
If you want to calculate just cpu and are on linux, you can use the
"time" command like $ "time ffmpeg ..."

Probably to all 3. Why don't you try a few files and find out... :)

Sorry, I am writing a script try to deal with all kinds of videos or
audios, I need to know which kind of files we can't get it's duration
before play it really or can't be seekable or both. I have no these
kinds of sample files, so I can't try them really.

Anyone has these kinds of files? Can you provide them to me?

Thanks.

Consider video or audio streams.  None of those are seekable (without  
trick-play) as they come in across the network, and I regularly curse  
people who forget this and assume their demuxer can seek as much as it  
likes.  Some of them may give you a duration, some may have an indefinite  
duration (e.g. internet radio), some may lie.

How about the regular files exist in the disks? 

I know some kinds of
videos, e.g., MPEG-TS or MPEG-PS files report a zero duration using
"mplayer -identify -vo null -ao null -frames 0 filename" command, but
"ffmpeg -i filename" will give an estimated duration, some people call
ffmpeg's duration for these two kinds of files is a guessing way. These
two kinds of files report as a seekable file using the "mplayer
-identify ..." command. See: [MPlayer-users] mplayer -identify reports
incorrect information for some files: 
http://lists.mplayerhq.hu/pipermail/mplayer-users/2012-September/085323.html

I don't know any other kind of regular video or audio file existed in
the disk can't get its duration priorly or isn't seekable. I will write
some extra lines to deal with them if there are these kinds of files
exist.

Subject: [FFmpeg-user] ffmpeg choses variable framerate for 1080p video only
Message-ID: <CAP9=GZBcmWDv8i5kAhwuWnbqVjV+hxVmLjUKZ5r6xDThKfB4Qw@mail.gmail.com>

i have a script that creates certain video formats. it seems something
is wrong with ffmpeg.

my command line is the following:

ffmpeg -async 2 -i ".\input\%1%2" -f mp4 -c:v libx264 -preset slow -g
60 -level 41 -b:v 12000k -s 1920x1080 -aspect 16:9 -vf
"movie=watermark.png, scale=1920:1080 [logo]; [in] [logo]
overlay=main_w-overlay_w-0:main_h-overlay_h-0 [out]" -af pan="stereo:
c0=c1+c0 : c1=c0+c1" -c:a libvo_aacenc -b:a 128k -ar 48000 -ac 2
-threads 0 -y ".\output\%root_folder_name%\vids\hd\%1_1080p_12000_no_outro.mp4"

the command above produces a video with a variable frame rate even
though the source has a constant frame rate.

running the EXACT same command but changing the resolution to 1280x720
produces the correct result. (copies the frame rate setting from the
source.) the freame rate should come out as 29.970 CFR. Specifying a
framerate by using "-r 29.970" causes ffmpeg to keep the variable
frame rate setting but sets the minimum and maximum frame rate to
29.970.

obviously something is not right.. can anyone help?

Here is the ffmpeg config:

When I'm playing the output file in VLC, there are a lot of pixel errors and

Are there any more options i need to add to the string or is the
mkv-container not suitable for this action?
I also tried to output the stream into a .mp4-file (same behavior). When I
put it into a .ts-file VLC-playing freezes at the first frame.

TIA

i run the exact command i specified, then change the resolution ONLY
to 1280x720 then inspect the video with mediainfo. the 720p video show
constant frame rate while the 1080p show variable frame rate.
also the 720p video will play on a ps3 while the 1080p video will not.
ONLY the resolution was changed in between.

This version seems quite old, could you re-test with trunk?

what is your output of running ffmpeg -i "file" with 720p versus
1080p? Does ffmpeg seem to think the file is variable frame rate?

    Hello . I need help about two subject.
First of them is the syntax error in filter movie
. My aim is to join two stream in a video .
and with the overlay I can do two local video with ffmpeg
<!-- My code is -->
ffmpeg.exe -i 1a.avi -vf "[in] scale=iw/3:ih/3,
pad=3*iw+240:2*ih+220:200:100 [left]; movie=1c.avi,
<code>
like that . but when I try to replace 1c.avi with the rtsp://localhost ...
I got error 'unknown parameter '.

---> my seconde question is
- is it possible to 2x2 mosaic video show with ffmpeg ?
or which console tool I can succeed it ?
I couldnt use avis with videohub cause I didnt find any way to stream my
result .
IN ffmpeg
I can save or stream or convert my output .
I found that xuggle in java maybe do it but it is very hard the article
said.
Please help me . Best Regards Emre K.

Hi Geeta,

FFMPEG can produce DASH compatible TS files but not MP4 files.
FFMPEG cannot help you in creating MPD's either, it can be for transcoding
for multiple Representations.

Currently I am using FFMPEG to transcode and create TS segments, for MP4 i
still have to depend on GPAC(MP4Box).

I presume if you use rtsp://localhost ... by itself then it works?
Maybe you need to use filter_complex?

so you want 4 videos displayed at the same time?

Thanks Varun.
Do you use any specific configuration to create TS segments for DASH or its
the normal 'segment' options provided in FFMPEG?

Cheers,
Geetha

Thank you Roger for your interest .
If I use
----
ffmpeg.exe -i rtmp://localhost/live/me -vf "[in] scale=iw/2:ih/2,
pad=2*iw:ih [left]; movie=a.avi, scale=iw/4:ih/4 [right]; [left][right]
overlay=main_w/2:0 [out]"  -f flv rtmp://localhost/live/firstTwo

---
There is no problem , I take what I need .
But I wanna use

---
ffmpeg.exe -i rtmp://localhost/live/me -vf "[in] scale=iw/2:ih/2,
pad=2*iw:ih [left]; movie= rtmp://localhost/live/me1, scale=iw/4:ih/4
[right]; [left][right] overlay=main_w/2:0 [out]"  -f flv
rtmp://localhost/live/firstTwo

--
In this case ffmpeg throw ex. I think cause of ':' I try to escape this
charecter with backslash. But noway.
?t said 'missing key or no key/value  seperator found after key
//localhost...'
Error movie parameter args with rtmp://...
I presume movie parameter waits for .mp4 .avi etc. like amovie wait for
.mp3 etc.
---- Secondly yes . I want 2 x 2 4 video .
Now I can do it with the code above in 2 proccess.
1.step
I join side by side each of pair
then I have two 1x1 videos

then I join again 1 x 1 video top and bottom .
after that I get 2x2 video .
in this case it's not problem but
in 4x4 video ? what the hell am I do?ng ?

(Complete, uncut console output missing.)
I didn't test but is the space between "movie=" and "rtmp..." 
intended?

For a real-world stream, initialisation and reading the stream will 
have no measurable impact on the decoding time (and you don't have 
to write anything if you want to benchmark, see my earlier mails).

still waiting the console return.
And I wish this will help my first problem .
Any idea of giving 2x2 view in one command ? or

For a real-world stream, initialisation and reading the stream will
have no measurable impact on the decoding time (and you don't have
to write anything if you want to benchmark, see my earlier mails).

So there is the possible explanation: this mediainfo is hallucinating.

Do you have any actual problem with the resulting video?

Subject: [FFmpeg-user] visualising Filtergraphs
Message-ID: <5052F176.3040401@yahoo.com>

I am trying to use graph2dot, as per

http://ffmpeg.org/ffmpeg.html#graph2dot

but failing miserably.
For example:-

> echo "scale=iw/2:ih/2:interl=1" | \
graph2dot -o graph.tmp && dot -Tpng graph.tmp \
-o graph.png && display graph.png
Input pad "default" for the filter "Parsed_scale_0" of type "scale" not
connected to any source

I have tried adding -i infile and -vf in front, and then it complains
about "No such filter: -vf" etc.

The actual filter string works fine in a real ffmpeg command line.

I'm obviously missing something simple, but could anyone enlighten me
please?

You need to provide it with a self-contained graph, with its inputs and
outputs:

$ tools/graph2dot <<<'testsrc , scale=iw/2:ih/2:interl=1 , nullsink'
[Parsed_testsrc_0 @ 0x186c960] size:320x240 rate:25/1 duration:-1.000000 sar:1/1

digraph G {
node [shape=box]
rankdir=LR
"Parsed_testsrc_0\n(testsrc)" -> "Parsed_scale_1\n(scale)" [ label= "inpad:default -> outpad:default\nfmt:rgb24 w:320 h:240 tb:1/25
]"Parsed_scale_1\n(scale)" -> "Parsed_nullsink_2\n(nullsink)" [ label= "inpad:default -> outpad:default\nfmt:rgb24 w:160 h:120 tb:1/25

To answer my own post after input form elsewhere...

You need to start with "nullsrc=s=widthxheight, format= uyvy422,....."
to set up your source material parameters... the docs could be clearer
so I might submit a patch once I've sorted my main issue out.

the same original video was used to create both 720p and 1080p videos.
the only reason i discovered this is because the 720p (CFR) worked on
a PlayStation 3 and the 1080p (VFR) did not (The PS3 does not support
VFR). further investigating showed that FFMPEG was selecting VFR for
the 1080p video even though the command line is exactly the same
(minus bit rate and resolution)

Why do you think it is VFR? Is it because it doesn't play on the PS3,
and mediainfo says it is VFR?

That is not necessarily conclusive - it could not play for a number of
reasons, and mediainfo can easily be wrong - I've never ever seen an
ffmpeg dev remotely interested in what mediainfo has to say about a
file :)

What does *ffmpeg* say about it?

Cheers

Tom

to escape in windows you may need a ^

Anyway I'd recommend using filter_complex and two inputs instead of movie=...

for 2x2, i assume you want "4 videos all displayed at once, one in
each corner"? Overlay filter should be able to handle it, though I'm
not sure of the syntax...

When you do:
movie=rtsp://localhost/...

ffmpeg is parsing it like:

movie= FILENAME : OPTIONS

with rtsp=FILENAME and //localhost/... is interpreted like OPTIONS.

Thus you need to escape the filename, like:

movie='rtsp://localhost/...'

(first level of escaping)

Another level of escaping may be needed depending on your shell.

The best way to do it is to create a background with color source, and
then overlay video 1 and 2 in cascade (either using "movie" or the

Why do you want to know what he wants to do with his decoded stream?

post the first few dozen lines of the output of

ffprobe -i <yourfile> -show_frames

for both files so the timestamps of the first few frames of both files
(including what ffmpeg thinks the frame rate is) can be seen

It's a "raw" h264 stream? (I guess that's possible?)

If it is then

ffmpeg -format h264 -i input ...
might work...

Obviously because any video has to be coded *somehow* - so to ask about decoding 
h264 by itself is meaningless unless you just want the warm feeling of knowing 
that it's there in your computer's memory somewhere. I'm sure Carl is waiting to 
volunteer a simple command line to do this decoding, but wants to know how the 
OP would like his video presented to him, in order to choose a suitable output 
format.

Apart from the fact that it would be a (serious?) bug if -f h264 
is needed, I fear that a user who asks how to decode h264 will 
not be able to replace "..." with something appropriate.

Please note that ffmpeg does not support outputting VFR 
in mp4 since November 2010.
(All mp4 files produced by FFmpeg since November 2010 are CFR).

And when you're done putting something appropriate in there, someone's sent me a 
message in ASCII I'd like you to decode for me :-)

Message-ID: <1347645041798-4653464.post@n4.nabble.com>

Hi, I need to extract compressed H264 streams from MP4 files and pass it on
to another application. However, when I extract H264 stream from a Mp4 file,
I found this oddity. 

I generated my test MP4 with a valid H264 stream in it. I am able to play
the MP4 file using VLC. Then when I extracted H264 from the same MP4 file,
even FFmpeg couldn't recognize that output as a valid video stream. 

Am I missing some parameters? Please advise.

I've upgraded my ffmpeg version to 0.11.1

The result is unfortunately the same as before (still a lot of pixel errors
and interrupts every several seconds).

The "-r" doens't fix it.

With the new version also comes another problem: The Stream-Numers (#0.0,
#0.1,...) don't keep the same input-connections (so that #0.0 sometimes is
the video-stream, but sometimes #0.0 is one of the audio-streams)???

nope my friend , I try every escape combination for it but still the same
problem . Anyway I developed my code a bit and solve this problem
with
--
my bat
--
@echo off
cd c:\ffmpeg\bin
ffmpeg  -i rtmp://192.168.10.88/live/new -i rtmp://localhost/live/me
-filter_complex "[0]scale=iw/2:ih/2,pad=3*iw+20:3*ih+20:10:10
[first];[1]scale=iw/2:ih/2[second] ; [first][second] overlay=main_w/2+10:10
"  -b:v 32k rtmp://localhost/live/joinFirstPair
pause
---
but in this case waiting time kill me .
In wowza or red5 I can stream live very fast , but in ffmpeg I wait and
wait about 45 sec minumum .
I think I have to use different program , cause the security provider
company make this code write .
They can see 16 cam in a window , ffmpeg is a key and bridge for this work
I think .  I'm a php & java developer , what I do is ffmpeg engineer :S Any
Idea to solve this problem ?

I don't know what the problem is, but I'm wondering if maybe FFmpeg
isn't waiting for a keyframe to start decoding it...?

What's your full console output?
In general, http://ffmpeg.org/trac/ffmpeg/wiki/StreamingGuide#Latency
might help you with less latency...

 ooo yes , that is what I need , cause the further step is 8 stream 16
stream etc .  And it wont work in this speed , but still I think
they use different solution not only ffmpeg , I try to edit kernel of
ffmpeg , but I haven't much time , just call ffmpeg in php or
java show it in 4 x 4  , 2 x 2 or 2x3  but I'm in deep with the bat , look
at that without latency encoder the code is already complex .
and I've to make a formula that switch case , I must evaluate the time &
performance :/ I wanna be a farmer

Subject: [FFmpeg-user] Is it possible to convert yuv444p10le to gbrp10le
	without defaulting to rgb48le ?
Message-ID: <1347657202.98071.YahooMailNeo@web160304.mail.bf1.yahoo.com>

?
Both window and linux version are giving this issue:
?
ffmpg when convert prores to dpx always default to rgb48le which?yield 12M file size wilie standard HD 1920x1080?dpx are gbrp10le at 8.6M.

Is there anyway to get ffmpg to convert yuv444p10le to gbrp10le?? ??
?
Here are the output and thanks,
?

Hi Team
1. Suppose you have 720P video. and you are sending it to a Device which supports 720P resulution (like 1280X720.)
and now if you are sending the same video to a low resolution device which has pixel in range 960*640.
How much one could save as far as performance(Encoding/Bandwidth)  is concerned. Any suggestions?

First, you have to address the problem that the aspect ratio is different...

But then, I think it's safe to assume that bandwidth, for the same quality, is 
proportional to area. At least to a first approximation.

Yes it it.
Will youtube itself change the video resolution based on device or it is done at Device level? If it does at youtube server then reencoding will be done at youtube server itself at given/required resolution? Am i correct?

Subject: [FFmpeg-user] compile mistake of ffmpeg
Message-ID: <CAPAO5vt7qhLbQgnWKuuwrv13Te3KTaOW1L6kqm2FbrJ+MMwX3Q@mail.gmail.com>

Dear ffmpeg group:

I am a freshman to learn H.264, and I want to use VS2010 to compile the
X264 code. But the MINGW32 tell me, there are something wrong with my
compiling process. So I need some help from you. I use the ffmpeg-0.10.4
version, and follow the steps. However, it failed. I had attached the
config.log to find your help. Thank you, and WAIT Ur Response.

Mr. Cai

You appear to be scaling to 900 x 720 then padding to 900 x 720 and
asking ffmpeg to add 190 pixels at the top of the picture. I don't think
ffmpeg is allowed to break the rules of maths.

Do you mean something more like this?

ffmpeg -i input.avi -aspect 16:9 -vf
scale=900:530,pad=900:720:0:190:0xd28080 -sameq -y output.avi

Not that I'm saying it's going to look very good - but it's physically
possible.

what are you compiling exactly? libx264?
(hint: ffmpeg itself only compiles with mingw).

Excuse me in advance for the translation of my response (I'm french).

In fact that's the problem, I have an original video size 768x576
(ratio 4/3) and I want to add bands on each side (two bands of equal
size to the left and right) to convert this video in 1280x720 without
distortion (the video will keep its ratio 4/3) is simply the size of
the stripes on each side that will transform this video 4/3 to 16/9.

I must be able to find a generic method (because the original videos
are not all in 768x576) and may be changed upon arrival in 1920x1080,
1280x720, 960x540, or 852x480.

I would also do the opposite (transform 16/9 to 4/3 by adding strips
of the same size on the top and on the bottom).

I think the pad filter is the best way to do this, but how?, Can you
put me on the way?

I noticed that when you specify "-vcodec mpeg4" it seems to give an
output of 200 kb/s.  I assume it is targeting this and this is the
default?
Thank you.

It's what you might call a "known problem". I'm only guessing, but I'm pretty 
sure that the default value was sensible years ago when it was defined, and from 
then on, no one felt able to change it, since it might break expectations and 
there's no compelling reason to.

Unfortunately, it does trip up a few new users (like me, once) who wonder why 
the default quality is "terrible".

Basically, you need to set your bitrate (or choose a quality level, or something 
else that fixes it).

Totally agree. Maybe it should output a warning when it chooses such
an odd default...

Your English is probably better than mine.

Not according to ffmpeg:

Input #0, avi, from '/home/toto/blender/dronez.avi':
   Duration: 00:03:11.24, start: 0.000000, bitrate: 1536 kb/s
     Stream #0:0: Video: mpeg4 (DX50 / 0x30355844), yuv420p, 720x576

Your original video is a 4:3 standard definition 720x576 file. You might 
have a video player (QuickTime, for instance) that lies slightly and 
tells you the file is 768x576 because it knows that standard definition 
pixels are not square (although Apple should scale up to 788x576, but 
that's another argument).

I'm sure I will get flack for this - but this is the way I would scale 
that video (keeping your pink border):

-vf scale=984:720:interl=1,pad=1280:720:148:0:0xd28080

Those numbers might be unfamiliar to many, but retains the video's 
display aspect ratio to within 0.07%.

Then you must learn how to write a script that probes your source file 
first and calculates the scale and pad arguments for you.

My calculations of the moment are:

For a final 16:9 disposition with a 4/3 original video ... calculate:

* Calculation of the width (after scale): height x (4.0 / 3.0) ->
here: 720.0 * (4.0 / 3.0) ==> 960.0
* Calculating the size (width) of each band for example the left band):
(1280.0 - 960.0) / 2.0 ==> 160.0
--> band_width = (final_width - intermediate_width) / 2.0

In fact it's for my software: EnKoDeur-Mixeur (EKD). I'm the creator
and devlopper (with two other people). I've implemented this
fonctionnality for a moment but I put it up with the old syntax of
FFmpeg (padleft ... padright ...). If you're interested with the
software, you can see the links in my signature.

Check out this video (it's a teachware for this fonctionnality in EKD):

Message-ID: <CAC0U9k6=vjge0b_y8=obsecyjBmgKUfy=31efhTy_F8tSrcHLg@mail.gmail.com>

Hello,

I have a problem with converting video in images with mov and mp4 in
FFmpeg (with the static version: ffmpeg version N-44443-g570931d).

In both cases I get two videos whose weight is 2.8 kb. I tried with
other codecs and everything works fine ... is there a problem with the
mov mp4 and at this level?

Here is the syntax:

/home/toto/ekd_toto/linux_dependances_portables/ffmpeg/ffmpeg  -r 12

The output seem good but the video is unreadable on arrival and weighs 2.8 kb.

Here the output for the mov :

What do you mean with "unreadable"?
What does ffmpeg -i 16_09_12.mov show?

You are falling into the trap that the all of the pixels on a 720x576
line are part of the active 4:3 picture. Where as only 702 pixels are.

If you wish to ignore the calculated scale and pad values I gave you
above, and insist on sticking with your calculated numbers, then you
(like many before you and many to follow) will get the will get the
images 2.5% too narrow. I'm sure that will flatter most people, being
2.5% too thin, but it is wrong. Please believe the experience of 26
years at the BBC.

I'm interested - man mplayer lists:

spal:    768x576 (square pixel PAL)

Does this reflect a common misconception?

On the other hand 788 is not divisible by 16 ...

If you don't mind elaborating.

Yes - it is a common misconception.

This BBC web page had lots of information, until the great web cull of
early 2011, so here's a link to the way-back-machine:

http://replay.waybackmachine.org/20100826080627/www.bbc.co.uk/commissioning/tvbranding/picturesize.shtml

This Adobe web page describes how they got it wrong all the way up
before After Effects CS4:

http://help.adobe.com/en_US/AfterEffects/9.0/WS3878526689cb91655866c1103906c6dea-7f3aa.html

Ahh, I remember it well ;) but give them credit, they did bite the

That's not entirely true, at least as long as you do not
transcode with QT. Standard pal is exported e.g. from Final Cut
as is without fiddling of the display aspect ratio; or rather QT
does not recognize the DAR at all. Unless you tweak the "Scaled
Size" in the video properties settings it stays at 720x576. You
can then scale it to 788x576.

Thanks for the pointers - now I know why I had this nagging
suspicion that something was not quite right DAR-wise with my
transcodings. For the web I will probably crop so I can stay with
"simple" aspect ratios, something like:

-vf crop=iw-18:ih,yadif,scale=640:480,setsar=1:1

I'm trying to convert an MPEG Transport Stream from DVB-T to ProRes 422 for FCP with ffmbc.
My command line is :

ffmbc -i input.MPG -f mov -vcodec prores -acodec pcm_u16le -ss 00:00:03:00 -t 00:00:05:00 out.mov

I'm sure there is a lot of parameters i forgot for a best result but at this time my problem is  with the audio.
The result is good for  the video but there is no audio stream in the result ??
In the strem MPEGTS the audio is EAC-3.
i need help please ...

Thank's a lot

Stanislas

in fact the problem seems to have difficulty to synchronize audio and video

this alert is coming a lot of time when encoding : 

error, audio timestamps difference is too big, cannot compensate a/v sync

and the result is no audio in the file output.

Is the some parameters to force synchro when encoding ? like -async or something like that ?

Subject: [FFmpeg-user] Syntax for merging + positioning two video streams in
	.mp4 container
Message-ID: <505723B0.3040009@davidfavor.com>

It appears .mp4 containers allow for positioning information
of multiple video streams.

My goal is to do -vcodec copy with two video streams, where
the 2nd stream is positioned to the right of the first one,
creating a "side by side" video.

And... skip the transcode step via -vcodec copy.

If this is possible, pass along the syntax.

Thanks.

Does crop default to centred (I honestly cannot remember)? Otherwise 
you'll crop all 18 pixels off one edge.

And, if your video has sub-sampled chroma (422 or 420 for example) then 
you can only crop to even numbers, and you end up cropping 8 pixels off 
one side and 10 pixels off the other.

But, yes, that's the idea.

So i'm going to the other list, thanks Carl !

Isn't that the root of the 702/704 pixel argument....?

Yes. The crop filter takes additional parameters for x and y to
position the cropped area, but defaults to centered; see the
manual.

heh

Not sure. I assume so:
http://en.wikipedia.org/wiki/Chroma_subsampling#4:2:0

Feel free to correct my ignorance.

If that's the case I'll have to live with that (for web
conversions to a straight 4/3 aspect ratio).

Do you have any normative reference about that? It seems to contradict what
I remember (I'll have to dig into the standards again) reading.

Note that I do not doubt your 26 years of BBC, just I wonder who is doing
something wrong: it could also be the ones producing the padded 702 pixels.

What do you mean by weight? "bitrate="?
It may have to do with libx264 not the container.

Sorry for not realizing earlier (as said, there are multiple 
problems with your command line):
It of course makes no sense to specify both a quality and a 
bitrate, and since the bitrate is ridiculously small, this is 
probably the reason why the output video does not look very 
good.

You have to work it out from ITU-R BT.601-7 TABLE 4 and ITU-R BT.470-6 !

This gives (for 625/50):-

Number of samples per total line for each signal =864.

Analogue total line timing 64us
Analogue active line timing 52us

Therefore digital samples per active analogue line = 864*52/64 =>702.

The 4:3 aspect ratio dates back to analogue days and so aspect ratio
calculations must be based on the analogue picture width and height, i.e
702x576.

Hope this helps.

Are there any options in ffmpeg to influence the keyframe properties?

Hi Guys,

I am very new to ffmpeg, What I am trying to do is that, I have made some
changes in the ffserver code and have started the HTTP server.
Now, when I am trying to run the command to stream the media, it is giving
some error.
command: ffmpeg -i test.mp4 http://localhost:8090/feed1.ffm

I think by default it should correctly ignore the frames that precede
a keyframe, but I'm not too knowledgeable on the subject.

Or to put it another way.

The sample frequency of an analogue 'PAL' or 'SECAM' line is:

1 / 0.000064 * 864 = 13.5 MHz exactly.

Which makes the active 52 micro-seconds have exactly 702 pixels

0.000052 ? 13500000 = 702

I've heard people say that the size of a digital line is different to
the size of an analogue line. But that is not how it was (is, for those
places which have not gone all digital yet) transmitted, so is a wrong
assumption.

Exactly.

Yes - it saved me a lot of typing. Thanks Tim.


I think I'd like to submit
http://lipas.uwasa.fi/~f76998/video/conversion/ as evidence too, as
Jukka has a good way with words and a good selection of references.

out as VFR.

Message-ID: <CABJE5QtpVGgwG1akHnHLtHpqO9MGkE-46S+U3N8gcfaD8=fROw@mail.gmail.com>

Hello,

I wants compile ffmpeg with h264 library inside on ffmpeg.
I use this instruction (
http://ffmpeg.org/trac/ffmpeg/wiki/MacOSXCompilationGuide). All libraries
installed from "homebrew" but ffmpeg compile from sources.
For ffmpeg configure using command:

./configure  --enable-gpl --enable-version3 --enable-nonfree
--disable-shared --enable-static --disable-ffplay --disable-ffprobe
--disable-ffserver --disable-w32threads --disable-network --enable-libx264
--enable-libfaac --enable-libmp3lame --enable-libxvid --enable-libfreetype
--enable-libtheora --enable-libvorbis --enable-libvpx --enable-libass
--enable-fontconfig --enable-libopenjpeg --enable-runtime-cpudetect
--target-os=darwin --arch=i386 --enable-cross-compile
--disable-optimizations --enable-extra-warnings


configuration completes fine and make creates executable ffmpeg file (14
MB). But when I copied this file to another mac and try run app exist with
error:

ffmpeg
dyld: Library not loaded: /usr/local/lib/libx264.125.dylib
  Referenced from: /Users/derand/Desktop/ffmpeg
  Reason: image not found
Trace/BPT trap: 5


I think the x264 library not linked inside ffmpeg file. Can I somehow fix
it without installation x264 library to my second mac?

Thanks

yes it's possible . You can do it with the pad filter and the secondly
overlay .
ffmpeg -i  firstInput.mp4 -vf "[in]
pad=2*iw:ih:FromLeftPaddingInteger:FromTopPaddingInteger , scale=iw/2:ih/2
[firstOne]; movie=secondInput.mp4 , scale=iw/2:ih/2 [secondOne];
[firstOne][secondOne] 
overlay=theSecondVideoPositioningFromLeft:theSecondVideoPositioningFromTop "
out.avi
i.e

ffmpeg.exe -i double1.avi -vf "[in] scale=iw/2:ih/2, pad=2*iw:ih [left];
movie=double2.avi, scale=iw/2:ih/2 [right]; [left][right] overlay=main_w/2:0
[out]" -f flv rtm...
here is 
iw = input video width
ih = "" "" height
main_w = main screen width
main_h = main screen height
movie is the second source
left and right is the parameter that you describe , tag .
overlay is the filter
first video padding information can be written pad:THE GENERAL OVERLAY WIDTH
: HEIGHT  : FIRST VIDEO WIDTH : SECOND VIDEO HEIGHT.
If you want Top and Bottom View you can do this in this way

This means "compile all FFmpeg libraries as static libraries", 
not "add -static to the linking options" which I believe 
would fail anyway, but please test --extra-ldflags=-static.

(And since --disable-shared --enable-static is default, you 
may safely omit it.)

(Assuming there is a libx264.a file)
Remove the libx264.dylib file (temporarily) from your build system.

This is not currently possible with FFmpeg.

Assuming you were the one uploading the Skype sample:
Did you already try to find out which mov atom 
allows QuickTime to understand it should place 
the video streams side-by-side?

I don't think the mov container supports unsigned 16bit pcm audio, 
if you have such a sample, please provide it.

It's a "raw" h264 stream? (I guess that's possible?)

If it is then

ffmpeg -format h264 -i input ...
might work...

Subject: [FFmpeg-user] Easier way to display program execution time on
	Windows
Message-ID: <019f01cd957b$f554e4f0$dffeaed0$@gmail.com>

Hi,

 

Following recent discussions about measuring execution time, I just
remembered that the command prompt is an easy way to display program
execution time on Windows. Execute:

 

prompt $P$S$D$S$T$G

 

This changes the command prompt to the form:

 

C:\Users\fvisagie 2012/09/18 10:55:50.45>

 

This makes it easy to read the system time before and after executing a
particular program.

 

As mentioned before, to display the current time at some point inside a
script, do:

 

echo. | time

 

Or to append that time to a log file, do:

 

echo. | time >>logfile.txt

 

Hopefully this is of some help.

 

Francois

As said, "-f h264" should not be needed.
(But I admit there are exceptions.)

Please define "picture frames".
(FFmpeg supports several dozen very different encoders, 
and most of the are definitely useful. So if you don't 
tell us what you want your decoded frames to look like 
nobody will be able to help you.)

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

But, Roger's command included an ellipsis "..." meaning that the rest of the 
command should follow. The problem is, you won't tell us how you want your 
output after you've 'decoded' it.

>   How can I get the picture frames just like doc/examples/decoding_encoding.c does.

Perhaps you mean that you want individual image files? If so, try this:

ffmpeg -format h264 -i input -an -qscale 1 %06d.jpg

This will give a whole bunch of individual JPEG files. If JPEG files were NOT 
what you wanted, then you have to tell us how you expect to "get the picture 
frames".

(does not work)
-an is unneeded, and the MEncoder documentation always 
strongly advised not to use -qscale 1 (but 2), I believe 
this still applies (but I may be wrong).

Fair enough; I copied the params from here
https://sites.google.com/site/linuxencoding/ffmpeg-tips
after doing a 'reality check' in my head.

Shall we suggest
ffmpeg -format h264 -i input -qscale 2 %06d.jpg
then?

That will still not work, but it does not matter 
because imo as long as the op does not give a little 
more information this is all just guessing.

It works for me, I just tested it. I do get a warning that says "Please use -q:a 
or -q:v, -qscale is ambiguous". I was hoping that serving the OP his output as 
JPEGs might prompt him to tell us what he /really/ wanted.

did you try this ?
-vf = "scale=x:y , pad:W:H:PadX:PadY"

if you don't have a libx264.a file then you may need to configure and
build x264 like
 --enable-static

I assume you already have libx264 libraries installed locally?

Subject: [FFmpeg-user] BGR24-YUV420-BGR24 conversion on raw video
Message-ID: <1347970849712-4653539.post@n4.nabble.com>

Hello.

I am tring to find an explanation on this peculiarity: 

1) Introduce a raw BGR24 avi video and transcode it to YUV420 using ffmpeg
-i rawinput.avi -vcodec rawvideo -pix_fmt yuv420p output.yuv
2) Transcode it back to BGR24 avi using ffmpeg -s 848x480 -i output.yuv
-vcodec rawvideo -pix_fmt bgr24 raw_decoded.avi
3) Compare PSNR, AbsDiff and UIQ results on the original rawinput.avi and
raw_decoded.avi

Results: Comparative PSNR, AbsDiff and UIQ measurements on Y-components
indicate that the raw_decoded.avi has changed (ie PSNR-Y way less than 100
dB). Change definitely should be expected on U and V components but I did
not expect any change on Y component.

Any ideas?

I use the regular segment options in ffmpeg to create TS segments.
I am working on some other tools, to see whether i could use them for DASH
segment creation.
How are you creating segments and mpd currently?

In BGR24 each component has values in the range 0-255

They will be mapped to YUV where Y is in the range 16-235. Therefore some
levels are lost as there is not a direct one-to-one mapping.

Those YUV levels will then be mapped back to 0-255 when you return to
BGR24. Again, there is no one-to-one mapping so more loss of levels (and
dithering) so worse PSNR.

That is not valid syntax for FFmpeg.

Subject: [FFmpeg-user] Is pcm_bluray to pcm_s16le lossless?
Message-ID: <CAKYWZ4dtEPLLfn=1s+XHuBKHQXYXm4DMeSVK9R7akop08LT23w@mail.gmail.com>

Hello,
this is a short question: Is converting pcm_bluray to pcm_s16le lossless?

Long story:
I got a Blu-Ray m2ts container with:

Input #0, mpegts, from '00003.m2ts':
  Duration: 00:47:23.17, start: 4198.958300, bitrate: 36670 kb/s
  Program 1
    Stream #0:0[0x1011]: Video: h264 (High) (HDMV / 0x564D4448), yuv420p,
1920x1080 [SAR 1:1 DAR 16:9], 23.98 fps, 23.98 tbr, 90k tbn, 47.95 tbc
    Stream #0:1[0x1100]: Audio: pcm_bluray (HDMV / 0x564D4448), 48000 Hz,
stereo, s16, 1536 kb/s

I used this command to mux it into a mkv container while converting
pcm_bluray (with afaik is signed 16bit big endian) to pcm_s16le (signed
16bit little endian) and copying the H.264 stream.
ffmpeg -i 00003.m2ts -c:a pcm_s16le -c:v copy 00003.mkv

Result:

Input #0, matroska,webm, from '00003_wav.mkv':
  Metadata:
    ENCODER         : Lavf54.25.104
  Duration: 00:47:23.17, start: 0.000000, bitrate: 34856 kb/s
    Stream #0:0: Video: h264 (High), yuv420p, 1920x1080 [SAR 1:1 DAR 16:9],
23.98 fps, 23.98 tbr, 1k tbn, 47.95 tbc (default)
    Stream #0:1: Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s
(default)

To my understanding this should be lossless, right? But somehow the m2ts
container is 12.1 GB large and the mkv container is 11.5 GB. There are no
further streams or attachments in .m2ts and just copying the h264 stream
shouldn't change the size either. I'm not quite familiar with m2ts
container but that would be a huge overhead for just the container.

I need to be sure that audio didn't loose quality. Please let me know if
you got an idea why the file size is smaller. Thanks.

I also included the log but there doesn't seem to be anything special:


ffmpeg -i 00003.m2ts -c:a pcm_s16le -c:v copy 00003_test.mkv

window 091412 update still gave the same exact error as 090712 setup. Perhaps there is some else I may be missing from win7 ffmpeg setup for 

getting it update to current git head ?


On rhel6U2. after much attempt, I think the ffmpeg config? miss the requied? but since then I had no luck on rhel6U2 to get away from the following? after git clone git://git.videolan.org/ffmpeg:
[root at dellpc ffmpeg]# ./configure --prefix=/usr --enable-shared --enable-libmp3lame --enable-gpl --enable-libfaac --enable-libvorbis --enable-pthreads --enable-libfaac --enable-libxvid --enable-x11grab --enable-libgsm --enable-libx264 --enable-libtheora --enable-libdc1394 --enable-nonfree --disable-stripping --enable-avfilter --enable-libschroedinger --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-version3

These are already installed: 

gsm-1.0.13-4.el6.x86_64
gsm-1.0.13-4.el6.i686
gsm-tools-1.0.13-4.el6.x86_64

Is there a way to ship gsm in ffmpeg config ?

Thanks!

appears you can only overlay "directly over the top" of another movie.
 Though I wish this could be made optional :)

This works for me, with git head from the day-before-yesterday.

ffmpeg -i one.mov -i two.mov -i three.mov -filter_complex "[0]
scale=426:720:interl=1,pad=1280:720:0:0 [a]; [1] scale=426:720:interl=1

overlay=852:0" -an -aspect 16:9 -y ~/output.mov

Enjoy ;-)

Please note that MPEG transport streams are intended to 
work with non-lossless transmission methods while I don't 
think your mkv is still playable if you damage it.

(The conversion from s16le to s16le is of course lossless.)

Simply remove --enable-libgsm from your configure line.
It is unlikely that you will need it.

Yep, i had a read on it and found that i could move the initial screen to where i wanted, have 7 screens running now, works nice, bit hungry on the old cpu but hey could not get VLCs mosaic working.

Hm, first i would tend to demux and dump both audio streams to be sure it is 
the same.
Second: just a shot in the dark: m2ts is a transport stream, so you should 
have one "Packet" overhead every 188 bytes (depending on the standard) which 
means dpending on the standard something between 2 and 18 bytes overhead 
every 188 bytes. (not completely sure about the numbers, but 2 is definitely 
minimum)  That is in deed what i call a lot of overhead...
Like i said, just a shot in the dark, i never had a look into the m2ts they 
use on Blurays, but i dont think they invented their own TS standard with 
much larger Packets or similar...

Subject: [FFmpeg-user] Is pcm_bluray to pcm_s16le lossless?

Hello,
this is a short question: Is converting pcm_bluray to pcm_s16le lossless?

Long story:
I got a Blu-Ray m2ts container with:

Input #0, mpegts, from '00003.m2ts':
  Duration: 00:47:23.17, start: 4198.958300, bitrate: 36670 kb/s
  Program 1
    Stream #0:0[0x1011]: Video: h264 (High) (HDMV / 0x564D4448), yuv420p,
1920x1080 [SAR 1:1 DAR 16:9], 23.98 fps, 23.98 tbr, 90k tbn, 47.95 tbc
    Stream #0:1[0x1100]: Audio: pcm_bluray (HDMV / 0x564D4448), 48000 Hz,
stereo, s16, 1536 kb/s

I used this command to mux it into a mkv container while converting
pcm_bluray (with afaik is signed 16bit big endian) to pcm_s16le (signed
16bit little endian) and copying the H.264 stream.
ffmpeg -i 00003.m2ts -c:a pcm_s16le -c:v copy 00003.mkv

Result:

Input #0, matroska,webm, from '00003_wav.mkv':
  Metadata:
    ENCODER         : Lavf54.25.104
  Duration: 00:47:23.17, start: 0.000000, bitrate: 34856 kb/s
    Stream #0:0: Video: h264 (High), yuv420p, 1920x1080 [SAR 1:1 DAR 16:9],
23.98 fps, 23.98 tbr, 1k tbn, 47.95 tbc (default)
    Stream #0:1: Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s
(default)

To my understanding this should be lossless, right? But somehow the m2ts
container is 12.1 GB large and the mkv container is 11.5 GB. There are no
further streams or attachments in .m2ts and just copying the h264 stream
shouldn't change the size either. I'm not quite familiar with m2ts
container but that would be a huge overhead for just the container.

I need to be sure that audio didn't loose quality. Please let me know if
you got an idea why the file size is smaller. Thanks.

I also included the log but there doesn't seem to be anything special:

Apparently nobody (including myself) really understand pkg-config.

Here is an answer from fontconfig people:

I'm really not sure how FFmpeg is supposed to "know" it's linking
against a static library, and thus know to pass the "--static" flag to
pkg-config.
Hmm...

I think you should be able to tell by running the "ainfo" filter
against it which outputs md5sum's?

I think that m2ts as used by bluray/avchd add an extra 4 byte timestamp 
(to help seeking) to the 188 used for broadcast, but are the same apart 
from that.

To answer my own question, it appears that it indeed was, see header:
https://github.com/FFmpeg/FFmpeg/blob/master/libavformat/librtmp.c

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

can anyone confirm for me that passing configure "--enable-librtmp"
actually does nothing these days?
I can't seem to find where it's used, though I'm not expert here.
Thanks!

It works for me, I just tested it. I do get a warning that says "Please use -q:a 
or -q:v, -qscale is ambiguous". I was hoping that serving the OP his output as 
JPEGs might prompt him to tell us what he /really/ wanted.

I don't think this is correct, see the usage of "$requires" 
in FFmpeg's configure file, in the section starting with 
"# build pkg-config files"

To clarify:
This is not always true because afaik there are 
32 bit pcm_bluray streams and the conversion 
from s32le to s16le is of course not lossless.
(But FFmpeg also supports pcm_s32le.)

It is of course true for the sample that you tested.

Sorry, this should be 24bit

which is internally stored as s32le in FFmpeg.

Subject: [FFmpeg-user] can't use x264opts to set qpfile
Message-ID: <CAKYWZ4fLbEgDbSVLyQCZibAHOxFiNG=Gnes9PaZFTwJvaS21Gg@mail.gmail.com>

Hi,
I want to use x264's option --qpfile to make it insert IDR frames in some
places (chapters).
FFmpeg has this option: ?-force_key_frames[:stream_specifier]
time[,time...] (output,per-stream)? However it's based on time stamps and
I'd rather give the frame number directly.

> ?x264opts options?
>    Allow to set any x264 option, see x264 ?fullhelp for a list.
>    options is a list of key=value couples separated by ":".

Well it does *not* allow to set all x264 options, at least I can't set:
-x264opts "qpfile:frames.qp" (something like -x264opts "rc_lookahead=100"
however works, just qpfile doesn't)
> [libx264 @ 035144e0] bad option 'qpfile': 'frames.qp'

Using x264 directly, --qpfile frames.qp works easily:

> x264.exe --fullhelp | findstr qpfile
>       --qpfile <string>       Force frametypes and QPs for some or all
frames

Is there a reason why I can't set --qpfile with -x264opts? Both x264 and
libx264 are built from the same source.

Message-ID: <CFEF7B04-918B-44EA-80F1-74C056018970@axz.ro>

Hi,

Every now and then ffmpeg fails when remuxing a mpegts file with the following error:

[mpegts @ 0x1677a60] H.264 bitstream malformed, no startcode found, use the h264_mp4toannexb bitstream filter (-bsf h264_mp4toannexb)
av_interleaved_write_frame(): Invalid argument

The file I am remuxing can be downloaded here: https://www.dropbox.com/sh/b8v81l4l7lhjgj0/6Klxfejcki

I am thinking this is a bug and even if there is an error in the stream the remuxing shouldn't break. I am able to play this file just fine.

The comand and output:

Thanks Mark! :)

So, the good old BT.709...

Is there any way to force the conversion to full 0-255 range? I wouldn't
want to be bound by ancient TV technology...

It's kinda hard to test concept codecs like the H.265 (which uses raw yuv as
test videos) if the comparison uses raw bgr24 avi for test material. The
metrics would be utterly useless. Of course PSNR is never conclusive if
comparing codecs and therefore I use also AbsDiff and UIQ. Possibly SSIM, if
we are successful in implementing that.

Offtopic: H.265 test encoder is seriously buggy. It was even missing an
include line on the source code, so it wouldn't build. Luckily one guy here
knows his C++.

Maybe it can't find a font or something?

FFmpeg refuses to write invalid streams, the video 
stream in your sample is so damaged that it is not 
possible to write a valid transport stream on remuxing.

If you think there is a bug, please open a ticket on 
trac (consider cutting your sample to ~20 MB)

Yes, it is quite simple: libx264 has no such option.  The qpfile is a
feature of the command line encoder (x264.exe).  I don't know of a way
to do the same using ffmpeg.

I don't think so. If libass can't find font it show message like:
fontconfig: Selected font is not the requested one: 'DejaVu Sans' !=
'Trebuchet MS'

VLC player is capable of playing it just fine.

Is there a filter or a way to relax the validations?
I was expecting the copy codecs to just copy data.

Thanks for your attention,

If you set "-loglevel debug", do you see ASS-related messages?

Order of libraries specification matters. Try with:
--libs libavformat libavcodec libswscale libavutil 

that is from the "biggest" to the "smaller".

Thank you for your suggestion.  Unfortunately, the end result is the same:

$(...) is recommended over `...`, but that is unrelated.

Libraries should be added after object files, in dependency order. For
shared libraries that does not matter much but for static libraries this is
mandatory.

Also, this command line seems too complex: you are requesting the cflags
twice, for no reason since you are only linking.

I didn't know that.  Thank you.

Thank you Nicholas.  This fixed the problem.

You're right.  This is a bug in the Makefile.  I'll fix it.

Thanks again!

Subject: [FFmpeg-user] FFmpeg for Android
Message-ID: <CACSc5E0io27t-KhODpbyvU=QBNvQeDyF=E_fnCG1CXziZ=c_0w@mail.gmail.com>

FFmpeg for Android is my attempt to create FFmpeg port for Android. Release
files are available on Source Forge.

http://sourceforge.net/projects/ffmpeg4android/

My goal was to create FFmpeg library which can be compiled under Android
source code tree, using Android NDK. I tried to do this by enabling proper
library configuration with configure script, making no changes to files in
official FFmpeg release archives, using makefiles from official FFmpeg
release archives as initialization scripts for variables used in Android.mk
files, and enabling building of all libraries and tools.

This is work in progress, tested only on latest Android master branch, arm,
NDK-r8, platform-14.

Feel free to test, suggest changes and report issues.

Thanks

Srdjan Obucina

Subject: [FFmpeg-user] FFmpeg error while streaming to RTSP server
Message-ID: <1348136926734-4653590.post@n4.nabble.com>

Hi All,

I am very much new to Streaming.  what I am trying to do is to stream a
static file over RTSP server.

Steps that I am doing.
*
1) My config file for the ffserver is as below:*
RTSPPort 8544
<Feed feed2.ffm>
   File /home/xyz/tmp/feed2.ffm
   FileMaxSize 200K
   ACL allow 127.0.0.1
</Feed>
<Stream test.sdp>
   File "/home/user/test.mp4"
   Format rtsp
   StartSendOnKey
</Stream>
*Note:* Some of the things are omitted.

2) I started the FFserver, and then try to connect to the server using below
command from my vlc client"
    with command: rtsp://xxx.xxx.xxx.xxx:8544/test.sdp

*I get the logs as:*

    ffserver version 0.11.1 Copyright (c) 2000-2012 the FFmpeg developers

"rtsp://xxx.xxx.xxx.xxx:8554 RTSP/1.0" 200 85

But, my VLC client is not able to connect and it says: "You input cannot be
opened."


##################################################################

Second thing that I was trying to do was to provide the feed to the ffserver
through ffmpeg
for that,* I was using the config file as:*

    Port 8090
    RTSPPort 8544

    <Feed feed2.ffm>
       File /home/xyz/tmp/feed2.ffm
       FileMaxSize 200K
       ACL allow 127.0.0.1
    </Feed>

    <Stream test.sdp>
       Feed feed2.ffm
       Format rtsp
       VideoFrameRate 15
       VideoSize 352x240
       VideoBitRate 256
       VideoBufferSize 40
       VideoGopSize 30
       AudioBitRate 64
       StartSendOnKey
    </Stream>

*Note:* some of the things are omitted.

1) start the server
2) ffmpeg -i /home/user/test.mp4 http://localhost:8888/feed2.ffm

*It gives the error:*

Simply remove --enable-libgsm from your configure line.
It is unlikely that you will need it.

In your new version, the dpx encoder supports gbrp10, 
unfortunately, there is only conversion from gbrp10, but 
not from another colour-space to gbrp10. I created 
ticket #1757.

Sorry for the useless advice, Carl Eugen

Subject: [FFmpeg-user] Strange newline character in mkv subtitles
Message-ID: <loom.20120921T001530-908@post.gmane.org>

I encountered a weird problem and I have no idea what am I doing wrong.

I have a number of MKV files with subtitle stream that play well in mplayer or
on my Blueray player (Yamaha BD667). But when I try to add a subtitle track to a
MKV file using ffmpeg, the subtitles work fine in mplayer, but on my Blueray
player I see a rectangle character instead of a newline. Every subtitle is shown
in one line with rectangles instead of new lines.

Here's what I tried:

Convered the SRT file to UFT-8:
# iconv -f CP1250 -t UTF-8 -c original_subtitles.srt >subtitles.srt

Tried both dos2unix or unix2dos on the subtitles.srt

Muxed the subtitles with the video:
# ffmpeg -i video.mp4 -i subtitles.srt -acodec copy -vcodec copy -scodec copy
video.mkv

The result looks the following:
Input #0, matroska,webm, from 'video.mkv':
  Metadata:

    Stream #0:2: Subtitle: text (default)

For comparison a working video is:

    Stream #0:2: Subtitle: text (default)
    Metadata:
      title           : xxxxx

I even went as far to look in the hexdump for the subtitle string and compared
the newline characters in both MKV files. In both cases I see 0d 0a as a newline
separator. The difference is that the ffmpeg muxed file the subtitle is
terminated by 0d 0a 0d 0a, whereas in the other file there no newline at the end.

Used ffmpeg 0.10.4.

Again, the strange this is that mplayer shows the sustitles correctly, Yamaha BD
player does not.

Any help appreciated!

Very good question... Must be some sort of mov atom
doing this, so makes no difference what syntax I use
with ffmpeg... the atom will be stripped and the
positioning info lost.

I'll see if I can figure this out.

What a great feature for ffmpeg to have...

Thanks for the idea.

If you have a preference for a tool that dumps
atoms and adds atoms, pass it along.

Android building system concept is much different than ./configure; make;
Android makefiles also have different format, and they require few specific
includes and variables in order to work. Provided makefiles does not have
them.

FFmpeg may be inserted in Android as a prebuild library, by configuring and
making library with standalone cross compiler (outside of Android source
code tree and outside of Android build system), and copying compiled
libraries at predefined location in Android source code tree, where Android
build system will pick them up and use them for linking and creating
filesystem.

The other way to do it, is to have FFmpeg source code included into Android
source code tree, and enable Android building system to build it according
to the building environment configuration. Considering all specifics of
Android build system, and countless possible Android building system and
FFmpeg configurations, writing proper Android makefiles for building FFmpeg
may be frustrating task.

The second way is preferred in the industry I am working in, and I am
trying to make this easier.

I think a mplayer with an up-to-date libass is likely to show the problem.
Could you try the latest FFmpeg (git head) and share the
original_subtitles.srt if the problem remains?

The ffmpeg libs support a number of different colourspaces for
conversion between RGB and YUV. Not sure if full range is one of them.
Unfortunately whilst third party users make use of this, ffmpeg itself
defaults to always using "SWS_CS_DEFAULT" which is set to 601.

As they say, I'm sure a patch would be welcome....

Thank you for explaining!

Is there a way to insert the required specific includes into 
the existing Makefiles? In case this is possible, it would 
allow easier building iiuc.

If you have a Mac then Apple's "Atom Inspector" might be the tool you want.

I dont think so. At least, not easily. Simple Android.mk (thats android
makefile), very close to minimal, looks like this:

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_SRC_FILES := \
    cmdutils.c \
    ffmpeg.c

LOCAL_SHARED_LIBRARIES := \
    libavcodec$(VERSION_SUFFIX) \
    libavdevice$(VERSION_SUFFIX) \
    libavfilter$(VERSION_SUFFIX) \
    libavformat$(VERSION_SUFFIX) \
    libavresample$(VERSION_SUFFIX) \
    libavutil$(VERSION_SUFFIX) \
    libpostproc$(VERSION_SUFFIX) \
    libswresample$(VERSION_SUFFIX) \
    libswscale$(VERSION_SUFFIX)

LOCAL_MODULE_TAGS := optional

LOCAL_MODULE := ffmpeg$(VERSION_SUFFIX)

include $(BUILD_EXECUTABLE)



include $(CLEAR_VARS) and include $(BUILD_EXECUTABLE) are those specific
includes, which are located in Android source code tree. First clears all
variables starting with LOCAL_, which are very important for the build
system, second instructs build system to build executable file.

Few other differences are:

Files in FFmpeg Makefiles are listed as filename.o, while Android makefile
requires real names, like filename1.c, filename2.S, filename3.asm.
There are default android linker and compiler flags which will always be
included in command line.
Android build system always strips files which will be installed on device
file system, and keeps non stripped files in a separate folder.

IMO, the best help Android build system can get from FFmpeg would be if
Makefiles provide variables which will contain values which can be used as
initialization values for Android makefile variables. Basically, this is
what I am trying to do now - get a list of files and flags from Makefiles,
according to configuration, and use them in Android makefiles.

It is perfectly to build an Android application without using their horrible
and unreadable makefiles, you just need to figure out the proper build
commands, which are unfortunately undocumented. Ant freezing when being
straced is also a bit of a problem. But once you figure out the proper
options, it works.

I was able, some time ago, to build ffmpeg using the compiler and toolchain
from the Android NDK, it just requires an awful lot of options. And also, I
do not understand the first thing about the various architecture options for
ARM.

If there are multiple bit streams should they possibly have different
names, as well, like "pcm_bluray24" kind of like how pcm does it?

What are your VLC logs? what if you connect to it with ffplay?

You mean mpeg2video 4:2:0 should have a different name than 
mpeg2video 4:2:2? And h264 4:2;2 a different name than h264 
4:4:4? And alac 16bit a different name than alac 32bit?

No, I don't think that would be a good idea, especially 
since current FFmpeg's output already allows to differentiate.

Did you install libx264 and libopenjpeg before running the
ffmpeg ./configure?

	video
Message-ID: <CAEofhfNpes-ow4nkmvySkRBCQe+6tcoahuDYucbmdgC-maLdxQ@mail.gmail.com>

Hi,

I installed ffmpeg on my Mac running OS X 10.7.4: sudo port install ffmpeg

I am attempting to turn a series of png files generated from POV-Ray into a
video, preferably and H.264 encoded video at 24 fps, in 720p. There are 50
png files, rendered at 1280x720, 8 bit. In each case I get a video of 0
length, appears to be one frame, and attempting to play with the standard
Quicktime player.

I have tried a number of different ffmpeg commands, all yielding the same 0
length result. Please help me get the syntax correct

ffmpeg -i camp*.png -y camp.mpg
ffmpeg -i camp*.png -b 1200 -y camp.mpg
ffmpeg -i camp*.png -vcodec mpeg4 -b 1200KB -s 1280x720 camp.mp4
ffmpeg -f image2 -i camp*.png camp.mpg

This is the version details for the ffmpeg I have installed:

In fact subtitles encoded with "-scodec" ass do not work at all on my BD 
player. I used "-scodec srt" to make it display the subtitles at all, but 
was struck by the problem described.

Will try.

I tried the static build dated Sep 14th from http://ffmpeg.gusari.org/
static (found it from ffmpeg.org site). It makes no difference.

The original srt is there: http://napisy.info/napisy_info_45924_SRT.zip

Hi,

I didn't tried with ffplay.. but not it is working...
I had not mentioned the Format in the configuration file.

I mentioned it as:
Format rtp
and now it is working..

Thanks everyone.

Subject: [FFmpeg-user] -qcomp 0.8 with no effect
Message-ID: <505DF6AF.5080103@gmx.net>

Hello,

I want to bring a video, produced with ffmpeg from an audio stream and a 
huge amount of images, on DVD. Well, the resulting video I got was 4.9 
GB, which is a tiny bit too big, to fit on an average DVD.
I have read about the "-qcomp" modifier. But -qcomp 0.8 has absolutely 
no effect for me.

I don't want to reduce size or rate, but want to increase the 
compression ratio to produce a video from which I'll produce a .iso file 
to burn it on DVD. The time it takes for ffmpeg to produce this video 
doesn't matter much.
How and where can I make the -qcomp modifier effective?

I am using 64-Bit Debian Wheezy,

kind regards
Hugo

Apart from the fact that I don't see what else could 
help you except "reduce size":
I am not sure what you mean with "-qcomp". Please 
provide your command line together with complete, uncut 
console output.

my command line looks like this:

ffmpeg -i myaudio4video.mp3 -f image2 -r 25 -i frames720/frm%06d.jpg 
-sameq -target pal-dvd -aspect 16:9 -acodec mp2 -ab 192k -qcomp 0.9 -y 
myvideo.mpg

this works for me and it produces a fine mp2 video, which fits the 
screen-size standard for a DVD. But the resulting video file is just a 
bit too big for a DVD. (I don't have the output on this computer.)

I am aware that -qcomp 0.9 could probably be in a conflict with -sameq 
(if -qcomp would work at all).
According to the manpage are there also options like -fs to specify a 
file size, which I have not tested yet.
I will not change the screen-size, nor will I reduce audio quality. Just 
a bit more compression, a bit less video quality - if necessary - to 
make the resulting video fit the media. (4.9GB -->> 4.5GB)

with kind regards
Hugo

Subject: [FFmpeg-user] ProRes Quicktimes with audio not playing back reliably
Message-ID: <505E19C1.3000201@burner.com>

Experimenting with ffmpeg for Prores Quicktime creation on Windows so I 
can stop having to bounce stuff over to a Mac to do it, but am having 
some issues with the resulting files.

Upon a bunch of testing, it seems that the movies made with video AND 
audio are problematic;  If I make a video-only Prores Quicktime it plays 
back just fine, or if I make an audio only it plays back fine as well.

With both however I get unreliable playback, ranging from Quicktime 
Player (on Windows) playing back 'lurchy' or even freezing up entirely. 
  It's also not consistent;  It will play through sections fine one time 
and freeze up another, so it's not happening at exactly the same spot. 
Sometimes I'll get 2 seconds in and it freezes, sometimes it'll go for 
20-30 and then die.

So this seems like a muxing/interleaving issue with the video and audio 
ffmpeg is writing in such a way that Quicktime Player is getting a bit 
twisted up inside.  If I take for instance the separate video-only 
Prores and audio from ffmpeg and combine them myself in Quicktime Pro 
(using Copy from the audio movie and 'Add to Movie' on the video one) 
and save a new self-contained file, it plays back fine.

I've been searching through the list archives and the cloest thing I can 
find is:

  http://ffmpeg.org/pipermail/ffmpeg-user/2012-May/006612.html

However the FCP warning is not (yet) my problem since I can't even get 
them to work reliably on Windows, AND I've made >4GB files that still 
don't work.  But that thread suggested some sort of muxing problem that 
was supposedly fixed in the ffmbc fork, but I downloaded and tried that 
too and didn't have any better success - the movies behave the exact 
same way.  So I'm not sure what might be going on.

Here's my encode command line plus output:

Is this also a problem when you transcode the same media to something
other than ProRes, like JPEG (-vcodec mjpeg)? Or does the problem ONLY
occur with ProRes-encoded files?

Can you send me one of your ProRes files that exhibits this problem?
I'd like to have a look. You can email me off-list to get the details.

Hmm good question.  I just tried mjpeg and that seemed to work fine.

Absolutely.  I'll prepare some test files that aren't too huge and drop 
you a mail.  Thanks for taking a look at this!

(-f image 2 -r 25 should be unneeded)

-qcomp (that I did not know) works fine here, but since it 
affects bit-rate control, it cannot work with -sameq.

Please provide complete, uncut console output if you need 
support.

PS: You do know that -sameq does NOT mean "same quality"?

Does it work if you use another audio codec?
(aac with high bitrate)

then you should remove -sameq and add -b:v to set the bitrate.

from my experience with mencoder, -qcomp is used to balance how bitrate
will be used between high motion and still image, and extremely usefull
with two pass encoding. -qcomp doesn't have effect on resulting size, but
resulting quality.

Ah - forgot to finish testing that the other night as well (I was 
getting errors about AAC being 'experimental' and then got sidetracked 
on something else.)

But no, AAC doesn't work, nor does MP3.. still get glitchy 
playback/dropped frames.

For fun I also tried still using PCM and changing the bit depth and 
sample rate to no avail;  pcm_s24le at 48khz is still not good, 
pcm_s16le at 44.1khz is still not good, etc.

Back on the video front, I tried MJPEG as suggested by Thomas which 
works fine, and I also just did DNxHD and it plays fine as well.  So it 
seems to be something with Prores specifically.

Hi all,

Here are the specs of Youtube (sorry in french):

http://support.google.com/youtube/bin/static.py?hl=fr&guide=1728585&topic=1728573&page=guide.cs

I would consider anything that is recommended in this link (for 1080p,
720p, 480p, 360p and 240p).

Here is an example with FFmpeg (720p specs) :

/home/toto/ekd_toto/linux_dependances_portables/ffmpeg/ffmpeg  -i
"/home/toto/blender/dronez.MOV" -f mp4 -c:v libx264 -b:v 5000k -vf

"/home/toto/a/nouv_EKD/video/version_3/transcodage_vid?o/23_09_12_essai_nouveau_h264_mpeg4_avec_du_mov.mp4"

The result is good but if it can be better (and in accordance with the
recommendations of Youtube) ...

A question, what's that: D?bit audio 5.1 ?, How to include it in the
FFmpeg syntax?

Thanks in advance.

i'm not a france, but i think debit= bitrate, for 5.1 channel audio. if
your video is a home made,  then you don't need to think about it, since
usually it is a mono or stereo.

Well, nevertheless it works for me now, I just reduced the size of the 
video, which with -sameq (CARL, WHAT DOES THIS REALLY MEAN - IF IT IS 
NOT SAME QUALITY?) and without -qcomp was 4.9 GB  --  reduced to 4.0 GB, 
when "-fs 4500M" just had truncated the end of the video, which was not 
desirable.

with kind regards

Please do not shout;-)
It means same quantiser (which in your case is 
definitely not same quality).

As correctly explained, -qcomp should be used to affect 
the rate control in two-pass mode. That it also affects 
one-pass encoding is probably not unintended, but i'd 
say you abuse the option (to your disadvantage).

The correct way for you to achieve what you want is to 
calculate a video bit-rate (you know the length of the 
video and the audio size), and use two-pass encoding to 
reach the desired file size.
(If you are not completely happy with the result, you 
can use -qcomp to change the quality distribution.)

Hi,

(using a recent Gentoo Linux on a AMD64 system)

the second half of this sunday I have spent searching
the net and testing what I have found ... unfortunately
without success.

I have a piece of video recorded from a DVB-T receiver.

ffprobe shows this information about the file:

My desktop PC is able to play this video without any problems.

But I want also check, whether my Beaglebone (OMAP35x) single board
computer is capable of playing the video.

The display has 800x480 pixel with 16 bit colordepth.

With only a little stuttering using 

    mplayer -vo x11 Video.mpg

it is possible to play the video. 

But: The video does not fit onto the screen and has the wrong aspect
ration... "egghead syndrome"...

(I currently have no ffmpeg combo on the Beaglebone available since it
does not compile natively on it due to too less memory).

There is currently no hardware acceleration available on the board.

My plan is to resize the video to have 16:9 aspect ration (no
anamorphic...that is the pixel are quare sized with equal x and y
length) and downscaled to fit the screen size. The process should
neither create a  video in much lower quality nor should the file
soze explode.

I tried things like

ffmpeg -vf scale=-1:480 -i <input> <output>
ffmpeg -vf scale=-1:480 -qscale <n> -i <input> <output>   with <n>=1...4
I also tried to use "-setdar 16:9" which is documented on the net but not 
accepted by my ffmpeg.

Regardless what I am doing the resulting video is blown in size and/or has
crippled quality but it is always suffering from the egghead
syndrome when played on the beaglebone.

What I am doing so badly wrong here and why does all the stuff from
the net not work for me ?

Any help is very appreciated! Thank you very much in advance!

Best regards,
mcc

Is there no other vo working for this hardware?
x11 does not support hardware scaling and does not 
allow a decent playback performance.

It should be easy to disable some features that you don't need.

Thank you for your explanation. This sounds like an intelligent 
solution. My image size is 720 x 576, the fps rate is 25, so, I should 
have 10,368,000 pixels per second. Yet I don't know the number of bits 
to use for the color.
And even if, what would the ffmpeg command-line look like for this 
two-pass method?
With kind regards,
Hugo

Subject: [FFmpeg-user] error to compile ffmpeg git version
Message-ID: <505F9F7C.6000405@j1s.es>

Hi,
I'm trying to compile ffmpeg git version on Ubuntu 12.04 64 bits 
following these instructions: 
http://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide , but it fails 
the ffmpeg compilation.

The unique differences are:

   * I have configured x264 with "--enable-static --enable-shared"
   * I have configured fdk-aac without "--disable-shared"
   * I have configured ffmpeg with "--enable-gpl --enable-libfaac
     --enable-libfdk-aac --enable-libmp3lame --enable-libopencore-amrnb
     --enable-libopencore-amrwb --enable-librtmp --enable-libtheora
     --enable-libvorbis --enable-libvpx --enable-x11grab --enable-libx264
     --enable-nonfree --enable-version3 *--enable-shared
     --disable-ffserver --disable-ffplay --disable-ffprobe*"

But the compilation fails.
I attach the "config.log" and the output of make in "ffmpeg-make.log".
Thanks for your help.
Regards.

No currently not. I am trying to setup the kernel, which 
needs some internal patching, to support TIs firmware blob
and the adapted dss2/omaplfb drivers, but....that will
take time.

I know that -vo x11 is not the way to go, which drives me back to
my initial question:

 How can I rescale the video, that it is no longer anamorphic and the 
 pixels are square (equal length for x and y)?

  I didnt run more than the kernel and its modules and a console.
  It was the first step I tried....

  I will try it again and post the results here.

  Will this option results in the solution for my problems?
  (See question above).

I can confirm that on playing back some recent ProRes files in QT player
7 I was seeing random picture freezing/jumping with audio playing
smoothly, which, if you stopped and went back over the same material did
not occur/occurred in a different place. I was putting this down to
pulling the files over the network until I saw this thread....

My coding parameters were:-

ffmpeg version N-44123-g5d55830
-c:v prores -profile:v 3 \
-c:a copy \
(Audio was 4 streams of pcm_s24be)

| Closed GOP. GOP of half the frame rate.

Half the frame rate? keyint=12 for 25 fps? Or do they mean half
the frame rate in seconds, i.e. keyint=125 for 25 fps?

Subject: [FFmpeg-user] Audio lost after a while in live streaming
Message-ID: <1348486150018-4653651.post@n4.nabble.com>

Hi
I'm using ffmpeg to stream DVB-T signals through a LAN. Every things seems
OK till audio lost suddenly! as I read the logs, I guess the error that
causes this problem is: 
"Error while decoding stream #0:1: Invalid data found when processing input"

- Is it true?
- What is the reason?
- What is the solution?

Subject: [FFmpeg-user] optimized bitrate
Message-ID: <50604C90.4060200@gmx.net>

Hello,

I have made now some tests with the "-qcomp 0.7" option versus the "-b 
4000k" option and did not notice any difference in the results. Both 
videos were reduced in size as I had wished it would be.
I found out, that I had to put the -b option at the front of the command 
line, directly following the ffmpeg command, while the qcomp option hat 
to follow the modifiers of the video codec (near the end of my command 
line).

Now I would like to have a (Linux) bash script, where the right bitrate 
is calculated from the length of the audio or from the number of the 
single images, from which the video is made. I think that some formula 
to calculate the bitrate for the -b option for ffmpeg must exist already 
in the public domain somewhere, but I have not found it yet. (Something 
for my very low level of understanding since I am far from being a video 
or DVD or ffmpeg Expert).

With kind regards
Hugo

OK I've done some more investigation on this.

Copied a sample file locally, and it still exhibits the issue.

Created a test file with the same coding parameters as was used by the
sample file as above using the following command line:-

ffmpeg -f lavfi -i "testsrc=duration=600.0:size=720x576:rate=25" \
-f lavfi -i "aevalsrc=0::d=600.0" -f lavfi -i "aevalsrc=0::d=600.0" \
-f lavfi -i "aevalsrc=0::d=600.0" -f lavfi -i "aevalsrc=0::d=600.0" -map
0:v -map 1:a -map 2:a -map 3:a -map 4:a \
-vf "drawtext=fontfile=/usr/share/fonts/truetype/DroidSans.ttf: \
timecode='00\:00\:00\:00': r=25: x=(w-tw)/2: y=(1*lh): \
fontcolor=white: fontsize=60: box=1: boxcolor=0x00000000 at 1" \
-c:v prores -profile:v 3 \
-c:a pcm_s24be -ar 48000 \
-y Prores_test_A.mov

This file does not show any of the problems (as evidenced by QTPlayer
<apple I> info box showing the rate stuttering or any visible stutter of
the timecode, or scrolling rainbow).

I note that my original file, duration 11 mins 03 secs is 4.8G in size,
and the lavfi version, duration 10 mins is only 1.7G. A recoded version
of the original to the same codec and level (done in QT Pro) is just
over 5G (but the audios have been merged into a 4 channel stream from
the 4 discrete streams). This has no issues.

I therefore wonder if the problem is buffer related, with the more
complex material coded by ffmpeg exceeding a limit momentarily, with the
Apple coded material being within the limits, and simple material coded
by ffmeg just fortuitously staying within limits.

Hi 

 

I believe this is a fairly basic problem I am having as I am just starting
with ffmpeg.

 

I am creating a video from a set of still images and have been getting an
image size problem which I have tried to solve with a '-vf pad' control
parameter. The pad values I have put in are designed to make the width
divisible by 2 as required and yet not mess up the aspect ratio.

 

Below I provide the report output with the three problem lines in bold - i
am running this on a PC with Windows Vista. 

 

ffmpeg -vf "pad=1340x886" -i "%06d.jpg" -y movie.mp4 -r 1 -b:v 9600 -report

Surely the only sane interpretation would be that the GOP would be at most half 
a second, but obviously measured in frames. (i.e. your first example)

I can't comment on my sanity, I'm just surprised, the ffmpeg
default being 250.

First you have to know where I-frames aka key-frames are located, that is the place where you can put your -ss and -t points. Further often audio is 'delayed' in relation to the video-stream, so another hurdle.
The way I solved it is by loading your a.mp4 in tsMuxeR/tsMuxerGUI and create a-1.ts a-2.ts and a-3.ts, splitting by time is one of the reliable options the tsMuxeR combo provides. The resulting ts files have 'ongoing' time stamps' which you need. Encoding with ffmpeg results in starting every file with 00:00:00.
Without encoding you can check if vlc plays the resulting a-1.ts a-2.ts a-3ts as if it where 1 file.
For parallel encoding you can check	ppss - (Distributed) Parallel Processing Shell Script - parallel ... which is a very nice set of scripts which enables you to optimally load your CPU-Cores, even if the machines are very different in performance.

The order of options matters:
You probably want to insert the video filter 
between decoder and encoder.

And I would strongly expect that you have to put 
the output file options "bv" and "r" in front of 
the output file.

Allow me to repeat that it is pure luck that qcomp works 
similar for you (in your specific case) as vb, -qcomp only 
makes sense with two-pass encoding (and does not affect 
the filesize in that case).

You can calculate a general bitrate by taking the maximum number of bits 
you are able to store, and divide by the number of seconds of material 
you have.

So say you had a storage medium that could hold 100000 bits and had 62 
seconds of material to store on it, your data rate couldn't exceed about 
16kbits/sec.

Don't forget to include your audio in the estimate, and some pad for 
overhead (DVD IFO files, etc.)  Then rather than trying to guess and use 
a q-factor, compress to the desired bitrate.

Actually, I think you need to place the -r before the input.
Otherwise, ffmpeg apparently assumes the input framerate is 25 fps,
and drops frames accordingly when you convert to 1 fps on the output.
Also, your pad command needs to be "pad=1340:886" rather than
"pad=1340x886". The following command worked decently for me:


ffmpeg -r 1 -i "%06d.jpg" -vf "pad=1340:886" -b:v 9600 -report -y movie.mp4

That depends on what you want to achieve...
(But I agree it is the more likely usecase.)

Hi,

Thanks for your help - I've got past that hurdle.

It produces an unexpectedly v small output file - could it be the "overread
8" messages in the report file below?

Also, I have tried various frame rates without any success.

If you have any ideas that would be great?
