Here's how you can use
ffmpeg to convert a
video (an MP4 video, for example) to an MP3 that you can load on your MP3
player:
ffmpeg -i video.mp4 -f mp3 -ab 192000 -vn music.mp3But there's a catch: You have to have ffmpeg and the libavcode-unstripped-52 packages installed on your computer. The problem is that second package is available in the multiverse respository only. To enable the multiverse repository, select Administration from the System menu, then Software Sources.
