You can use third part apps clive, it is a command line tool. Hope it helps you.

You can also use ffmpeg in addition to convert different format from flv or mp4 that you download from youtube.

I was recently able to find this site they provide a REST api for downloading videos, mp3 it seems like it is easy to use
