Comment (by llarevo):

 All requested testcases were broken with the current git, except the
 ffplay commands without -r 25. In other words: ffmpeg doesn't work neither
 with or without -r 25, while ffplay does work only without -r 25.

 In Detail:

Comment:

 To llarevo: thanks for testing, I believe I know what causes this bug and
 I have just posted a patch on ffmpeg-devel mailing list for discussion. As
 Carl suggested, please do not use "-t 300". Also using "-r 25" or not will
 not make any difference since you are capturing from a TV card using the
 PAL standard for which the framerate is fixed at 25fps and cannot be
 changed (you will only get a warning).

 Does it work without "-r 25"?
 Does ffplay work with "-r 25"?

 Please (re)move -t 300 - it (unfortunately) does not do what you (and I)
 hope.

 ffplay -loglevel debug -f video4linux2 -probesize 32 /dev/video0 works

 I forgot to mention here, that I made a short test with Ubuntu 10.04 LTS.
 This is shipped with ffmpeg 0.5.x and working fine ootb. When I download
 the 0.11.1-ffmpeg and build it as described above, I get the same error as
 in Fedora f17.

 That makes me wonder if one of your parameter isn't wrong: you specify -r
 25 which might be not supported by your card. Can you make some tests with
 something simple such as:

 {{{
 ./ffplay -f v4l2 -i /dev/video0
 }}}

 to see if it doesn't show anything? (for old version you might need to
 change v4l2 into video4linux2)

 I took a look into libavdevice/v4l2.c. This file was obviously not updated
 by the checkout command.

Comment (by llarevo):

 Thanks. I've two more questions.

 1. What version shall I checkout prior to apply the patch?

 2. Shall I then compile with "--enable-libv4l2" or without?

 Type "patch -p1" (and enter), then paste above code (from "diff" to
 ".den;" including the line break), and press Ctrl-D (twice), or save the
 code in a file and do patch -p1https://ffmpeg.org/trac/ffmpeg/ticket/1570#comment:4>

Comment (by llarevo):

 I don't know how to do this. I tried:
 {{{
 cd ffmpeg
 git checkout 70f7736
 gedit hack.patch
 }}}
 I copied your hack above and saved it in the file "hack.patch". After
 that, I did
 {{{
 patch -p0 < hack.patch
 can't find file to patch at input line 5
 Perhaps you used the wrong -p or --strip option?
 The text leading up to this was:
 --
 |diff --git a/libavdevice/v4l2.c b/libavdevice/v4l2.c
 |index 2808e13..0acd3da 100644
 |--- a/libavdevice/v4l2.c
 |+++ b/libavdevice/v4l2.c
 --
 File to patch: ^C
 }}}
 Then I tried
 {{{
 patch -p1 < hack.patch
 patching file libavdevice/v4l2.c
 Hunk #1 FAILED at 694.
 1 out of 1 hunk FAILED -- saving rejects to file libavdevice/v4l2.c.rej
 }}}


 Sorry - I have not really a clue what I'm doing there. I don't find the
 line
 {{{
 if (framerate_q.num && framerate_q.den) {
 }}}
 in the file "libavdevice/v4l2.c"

 Can you give me a short advice how to "try this hack with an upstream
 FFmpeg"? What means upstream? Shall I try the hack with the most recent
 version? How can I get it with the git checkout command? If so, shall I
 configure with "--enable-libv4l2" or without?

 Sorry, but this is the first time I deal with source code, so any advice
 is very appreciated.

 Thanks a lot.

Comment (by ubitux):

 Just to make sure, can you try this hack with an upstream FFmpeg?

 {{{
 diff --git a/libavdevice/v4l2.c b/libavdevice/v4l2.c
 index 2808e13..0acd3da 100644
 --- a/libavdevice/v4l2.c
 +++ b/libavdevice/v4l2.c
 @@ -694,7 +694,7 @@ static int v4l2_set_parameters(AVFormatContext *s1)

  }

 -if (framerate_q.num && framerate_q.den) {

  av_log(s1, AV_LOG_DEBUG, "Setting time per frame to %d/%d\n",
 framerate_q.den, framerate_q.num);
  tpf->numerator   = framerate_q.den;
 }}}

 (Since according to your report 70f7736 looks faulty).

 Also, could you post a complete command line and output with -debug 1
 (with an up-to-date tree but without the hack above) so we can have more
 information on the issue?

Comment:

 Typo: The regression was not introduced in 2009 but in 2010.

 Needless to say, that I can perform additional tests on request.
