How to extract audio from any video file in Linux

Want to extract the audio of your favorite musical video, but stuck because you use Linux? Just fire up the terminal and hit shmooze:

ffmpeg -i my_video_file.avi extracted_audio.mp3

Well, in the linux world, it's a pity if you don't give an alternate way to do stuff. So here it is:
mplayer -dumpaudio my_video_file.avi -dumpfile extracted_audio.mp3

This technique can be used to extract audio from AVI, MPG and FLV files.
