Okay, then I can work on the audio support (cook.so.6.0). This
shouldn't be too hard.

Yes - I have found more docs at home yesterday (my room is
a mess these days :)). I will start tomorrow - maybe one
or two days.

Have you done/will you do the format stuff (the 2 32 bit values)?
I have worked on it, but run into problems because I wrote them
in a structure which I put into sh->coontext inside the demuxer
initialization. But somewhere before codec initialization the value
has been changed. Unfortunately I didn't have the time to
fix it yet.

fyi: the rv30 codec format mask is 0xFFF00000 and the value
is 0x302xxxxx.

Can it play rv20 files?

AFAIR you have worked on sorenson in january. Have you had
more success since then? When the real player stuff is finished,
I am willing to look at sorenson and that other proprietary
audio format (don't know the name).
