I don't know, if avidemux will be packaged before that is added. I had a look at avidemux and packaging it would be a rather huge effort due to the way it uses FFmpeg: * It uses an old version of FFmpeg (1.2). * It applies custom (and rather strange) patches to FFmpeg. * It uses private FFmpeg API. This is pretty bad. :-/ Fortunately writing a bitstream filter for unpacking the packed B-frames turned out to be doable. I've posted a patch upstream [1].

Bug#781510: Consider using a tool like VirtualDub or avidemux to fix it.
Package: ffmpeg
Version: 7:2.6.1-1
Severity: minor
The comment displayed by ffmpeg on debian linux is rather useless (as of today):
[...]
[mpeg4 @ 0x1b5de20] Video uses a non-standard and wasteful way to
store B-frames ('packed B-frames'). Consider using a tool like

[...]
avidemux is still not part of debian #203211 and VirtualDub is windows
only. Please consider suggesting alternatives that works on Debian.

I think this is much more informative than the previous warning:
Invalid and inefficient vfw-avi packed B frames detected
avidemux is still not part of debian #203211
This should be changed, but that's difficult, because it uses an old
version of FFmpeg with custom patches.
But even if it's not yet in Debian, people can get it from elsewhere.
and VirtualDub is windows
only. Please consider suggesting alternatives that works on Debian.
Do you know of an alternative in Debian that could be suggested?
Anyway, the proper fix for this would be to add a bitstream filter for
unpacking the packed B-frames to FFmpeg. Then such files could be fixed
with FFmpeg, so there would be no need to suggest other programs.
There is an upstream feature request for that at [1].
Best regards,
Andreas
