FOURCC Header
Four-Character Codes (FOURCC) were introduced by Microsoft to clearly identify video data stream formats. The unique FOURCC value assigned to every compression format and pixel layout allows video frames to be passed between file and codec by ensuring the FOURCC of the source frame matches a FOURCC supported by the codec. FOURCCs describe the software technology that was used to produce multimedia data. By implication, they also describe the format of the data itself. FOURCCs are supposed to be registered with Microsoft by the vendors of the respective multimedia software technologies but not all vendors play by Microsoft's rules. Below is a DivX 4 encoded movie open in a binary editor. As you can see there are two places in the visible Window where the word divx can be seen.
The current FOURCCs registered with Microsoft appear in the following list.
