Four-Character Codes (FOURCC)

Codecs play a vital role in the digital landscape, enabling efficient compression and decompression of multimedia files.


At the heart of these codecs lie FourCC codes, unique identifiers that represent specific multimedia formats.

What is a FOURCC code?

FourCC (Four-Character Codes), as the name says, is a four-character code that serves as a shorthand representation of a specific video format or codec. 

It acts as a compact and standardized way to identify various video compression algorithms.

Each FourCC code corresponds to a specific multimedia format, enabling software and hardware to identify and handle video data correctly.

Here is a list of registered FOURCCs:
