[MPlayer-users] mencoder DV -oac copy coredumps

[Steven M. Schultz]

Hi !

	This used to work and I'm not sure exactly when it ceased working but
	mencoder coredumps when -oac copy is used with a raw DV file (the
	audio was going to be replaced later with aac or vorbis so -oac
	seemed more efficient than encoding to mp3).

mencoder -v -oac copy -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=2000 -o foo.avi redhotridinghood.dv

	This is with the freshest cvs versions of ffmpeg/libavcode and 
	MPlayer.

	That 'bps=' on the audiocodec: line looks very weird doesn't it?

	MPlayer can play the raw DV file fine - it seems that mencoder's the
	part that is having problems the audio data.
