Convert audio from WMV files to MP3

A while back some radio station website or somewhere had a video in WMV of KT Tunstall performing Black Horse and the Cherry Tree and I wanted the music for a plane ride today.

Usually I'd use vsound, I've been able do save the audio track of a video in realplayer, but for some reason it wasn't working for gxine.

Anthony Barker's blog had the concise steps needed to use mplayer to grab the sound.


mplayer -dumpfile outfile.dat -dumpstream some-video.wmv

mplayer -vo null -vc null -ao pcm -ao pcm:file=audio.wav outfile.dat

lame audio.wav audio.mp3

rm outfile.dat
