Found this resource about using mplayer or ffmpeg to extract the audio of an flv flash movie (like those from youtube etc.) and save it as an mp3 file.
I adapted the ffmpeg version with the -ab flag that allows me to specify audio bitrate:
ffmpeg -i input.flv -f mp3 -ab 192 -vn ouputfile.mp3
Change the 192 to whatever bitrate you want.
