Codec is short for coder/decoder.
To know what codecs are readable with VLC media player, see VLC Features Formats.
For portability to almost all decoders, we recommend
using the MPEG-1 standard of vcodec=mp1v, acodec=mpga, and mux=mpeg1. See the MPEG Wiki page for more details on the other MPEG standards.
To save a file in a different codec, you can use the transcoding wizard or transcode from the command prompt with a command like this:
vlc file --sout='#transcode{vcodec=mp1v, vb=1024, acodec=mpga, ab=128}:std{access=file, mux=mpeg1, url=C:\file_name.mpg}'
