mpv/libmpdemux/muxer_rawvideo.c
rfelker 3892465935 processing audio is sometimes essential for a/v sync, so 1000l to
whoever made rawvideo muxer disable audio!!

with this patch, audio is processed but simply thrown away by the
muxer. various 'error' conditions in rawvideo muxer are removed to
make it work. feel free to re-add them if they can be done without
breaking anything, but do not use printf !!!!

btw old behavior can be obtained by manually specifying -nosound.
