Coming back to you request, something like this should work:

mencoder ~/media/video/old\ school.avi -ovc copy -oac lavc -lavcopts acodec=mp3 -noskip -ss 1441.4 -endpos 260.1 -o tmp/part1.avi mplayer -dumpaudio -dumpfile tmp/part1.mp3 tmp/part1.avi rm tmp/part1.avi

no, mencoder can't output raw audio files such as mp3 (except pcm), and btw you shouldn't use lavc to output mp3: use -oac mp3lame -lameopts ... instead. Your only chance with mencoder is

$ mencoder ~/media/video/old\ school.avi -ovc

frameno -oac mp3lame

-lameopts br=128 -noskip -ss 1441.4 -endpos \ 260.1 -o tmp/part1.avi

Mmmm. I was already sleeping when I proposed -ovc copy. Of course -ovc frameno is better. And the raw mp3 file can be extracted with mplayer -dumpaudio from the avi file.

You guys are missing the point. If you want to extract the audio from a 3 hour concert video, that can be done in minutes on a good machine with a transcoder, or it can be done in 3 hours with the mplayer -dumpaudio technique. I'll attempt to elicit support from the developers and/or develop a patch as time permits. -bryan
