Creating mp3 files
- Note: If you try to create mp3 files it probably won't use the best compression techniques!
You can make mp3 files by using the mp3 audio codec. .mp3 files do not have a container, so you should use the dummy container. You should also specify the --no-video option if you're taking audio from a video.
An example of this at the command prompt is (all on one line):
% vlc "input_file" :no-video :sout='#transcode{acodec=mp3,ab=128}:std{access=file,mux=dummy,url="out_file.mp3"}'
