[wplug] ripping mp3 audio track from video (flv)

[Brian Sammon]

So I have a .flv file I downloaded from youtube.  I'd like to pull the audio 
track from it, which is already mp3-encoded, to put on my audio-only mp3 
player.

Does anyone know of any tools for doing this other than playing the video and 
re-encoding the output?  It seems to me that this should be a really quick 
operation if I find a program that doesn't re-encode the data.

My first guess was the ffmpeg program, but I can't really tell whether it does 
the re-encoding thing, and in general, I'm a bit overwhelmed by its hundreds 
of commandline options.
