Oh, it was just to force the audio recording from /dev/dsp even with a
v4l card without audio capabilities : 
s/param_noaudio = 1/param_noaudio= 0/ in tvi_v4l.c.
I'll try the cvs version later instead. It works with alsa and oss
emulation, but not with oss only with this card.

By the way you are right, it was an intel sound card based on an ac97
chip.

Sorry, I am a little lost here. How can you use these key frames for
cutting a sequence ???
I mean, with mencoder there does not even seem to be a way to cut
sequences : you can start and end at specific points to define a
sequance, but then you can't join the resulting files. You have to use
another program and it becomes a mess (avicat works, but it is very
sensitive to what you have for the audio track - it does not like mp3,
and it hates mp3 vbr).

Is there something special to do to use these keyframes, or is it just
an external program to use ? (by the way AFAIK, there is no program able
to edit divx files in linux)
