A FourCC -- also spelled FOURCC or fourcc -- is a 4 byte identifier which specifies the format of a video stream.

Every codec has its own unique FourCC.  Commonly, each byte corresponds to a printable character in the [http://en.wikipedia.org/wiki/ASCII ASCII character set], making the sequence human-readable.

This is very useful for determining whether {{VLC}} can decode a video stream.  For audio streams, a [[TwoCC]] is used.
