What is AVParser? Is there any documentation about it or is there some 
other implementation that could be used as an example?

Regarding some "down to earth" and practical solution for '-ac ffmp3' 
support problem, wouldn't it be easier to drop avi support from 
libmpdemux and use lavf instead of it, but keep libmpdemux code for 
matroska, ogg and other container formats that are causing problems at 
the moment? In this case I would need to reorder some entries
in 'demuxer_list' from 'demuxer.c'. Is that right?

Are there any known regressions related to using lavf for avi files in 
mplayer?
