Four-Character Codes (FOURCC)
Microsoft® multimedia technologies use a special set of codes that are four characters in length. These codes, called four-character codes or FOURCCs, are stored in file headers of files that contain multimedia data, such as bitmap images, sound, or video. FOURCCs describe the software technology that was used to produce multimedia data. By implication, they also describe the format of the data itself.
DirectDraw and Direct3D applications use FOURCCs for image color and format conversion.
FOURCCs are registered with Microsoft by the vendors of the respective multimedia software technologies. Some common FOURCCs appear in the following table.
