There may be programs to demux it directly, but mplayer can just dump the audio as a wav file. (Maybe mplayer/mencoder can demux directly?). Try

Code:

mplayer iput.mov -vo null -ao pcm:file=audio.wav:fast

This will give you the raw audio file named audio.wav. Then you can convert it to mp3, ogg, or whatever.

You could use the "-dumpaudio" option also.

Code:

mplayer file.mov -dumpaudio -dumpfile audio.mp3

MPlayer will also tell you the audio codec used in the video, so you know what extension to use for the dumped audio file.

Code:

mplayer file.mov 2>/dev/null | grep "DECAUDIO"
 DECAUDIO: Opening audio decoder: [mp3lib] MPEG layer-2, layer-3
 DECAUDIO: AUDIO: 48000 Hz, 2 ch, s16le, 128.0 kbit/8.33% (ratio: 16000->192000)
 DECAUDIO: Selected audio codec: [mp3] afm: mp3lib (mp3lib MPEG layer-2, layer-3)
