video to mp3

I had a desire to take a video file and extract the audio track into an mp3 file, so I ended up using a variant of the mp4 converter script to do the job.

[ "$1" ] || {
  echo use: $0 file...
  exit 0

for file in "$@"; do
  ffmpeg -i "$file" -acodec libmp3lame -aq 100 "$file.mp3"

This script should work on most audio or video formats and makes variable bit rate high quality mp3 files.
