Ripping sound from a video avi file to mp3

I have a video avi file and would like to rip the sound from this to make a mp3.

What program can do this?

Many thanks

Mencoder will probably do it. (MPlayer)
If you want a gui, Avidemux will do it.

Cheers for the posting.

I have been looking at mencoder and trying to work out the instructions. Does:-

mencoder tcextract -i filename.avi -x mp3 -a 0 > all_audio.mp3

sound right?

I believe "tcextract" is part of "transcode".
I'm only guessing but it looks like your command is assuming
that the source avi has mp3 audio. Do you know this for sure?

If it DOES for sure, you can do:

Code:

mplayer -ao pcm -vo null -vc dummy -dumpaudio -dumpfile myvideo.mp3 myvideo.avi

If it DOES NOT, you can do:

Code:

mencoder myvideo.avi -o myvideo2.avi -oac mp3lame -ovc lavc

Then:

Code:

mplayer -ao pcm -vo null -vc dummy -dumpaudio -dumpfile myvideo.mp3 myvideo2.avi

Then you can get rid of myvideo2.avi
