How can I extract audio track from video file and save it as MP3? [duplicate]

Very simple CLI solution:

ffmpeg -i VIDEOFILE -acodec libmp3lame -metadata TITLE="Name of Song" OUTPUTFILE.mp3

In case you don't have ffmpeg installed:

sudo apt-get install ffmpeg

You can do this in VLC.

Once you have started VLC:

  1. select "Media" --> "Convert/Save"
  2. Click "Add..." and select the file you want
  3. Click "Convert / Save" (on the bottom)
  4. Provide a "Destination file:"
  5. Select the "Profile" (i.e. "Audio - MP3", "Audio - Vorbis (OGG)", etc.)
  6. Click "Start"
  7. Relax and enjoy your shoes

You can install VLC from Synaptic or the Software Center.
