This is an audio codec. The name to use at the command line is mp3. This codec can be used inside the dummy (raw), mpeg, avi, matroska and mp4 containers. |
MP3 is a popular type of audio compression described by the MPEG-1 specification (MP3's full name is MPEG-1 Layer 3 Audio).
VLC can play and create MP3 files.
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:
% vlc "input_file" :no-video :sout='#transcode{acodec=mp3,ab=128}:std{access=file,mux=dummy,url="out_file.mp3"}'
