Extracting audio as MP3 from video files

[O-pos]

Hello,

I have video lessons from that I would like to extract audio as mp3 files to be able to play them on my iPod. How is it possible?

The fideo files are avi ones, but I don't know how the audio is encoded.

I would like to use mencoder for that, if it's possible.

Any ideas?

Try AVIMuxGUI.

Mencoder does not handle audio nearly as well as ffmpeg.

If the audio is already mp3, try a

ffmpeg -i '/path/to/file' -vn -acodec copy '/path/to/output.mp3'

otherwise, encode to aac mp4:

ffmpeg -i '/path/to/file' -vn -acodec mpeg4aac -ab 96000 '/path/to/output.mp4'

Where "ab" is the bitrate in bps.

And I think AVI-Mux GUI works under Wine.
