Using FFMPEG mp3 audio extractor with Youtube-DL

Eventually you will need to extract audio from the video files you downloaded with Youtube-DL.

If you face this error :
[youtube] xxx : Downloading webpage [youtube] xxx: Extracting video information [youtube] xxx: Downloading DASH manifest [ffmpeg] Destination: xxx.mp3 ERROR: audio conversion failed: Unknown encoder 'libmp3lame'

Be sure to install libav-tools (tested on Ubuntu) and you're good !
