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. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@16806 b3059339-0415-0410-9bf9-f77b7e298cf2
