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.
