Earlier I talked about “how to download youtube videos“. So lets look at one of the methods of extracting the audio file out of the flv file or of any video file.

Most flv files or video files have mp3 audio embedded inside the video. In such cases trying this command should do the trick:

ffmpeg -i video.flv -acodec copy my_audio.mp3

I am assuming that you have ffmpeg already installed. If you are a linux user (Ubuntu 10.04, Fedora 13 etc) then you can install it using your package manager:

sudo apt-get install ffmpeg
or
yum install ffmpeg

Windows users would have to download it from here.
