How to rip the audio from a youtube movie

(on Unix)

1. Download the flv file with youtube-dl
2. Extract the audio like so:

   mplayer -dumpaudio nodame_theme.flv -dumpfile nodame_theme.mp3

   (thanks to here)

This method allowed me to rip the World In Action theme to mp3 for my ringtone… of course you could always use vixy.net.
