Compression Formats

The digital video device provides video playback and recording support through its open compressor/decompressor (CODEC) architecture.

The following table describes the digital video compressors and decompressors (CODECs) available with OS/2. The CODECs are represented by unique FOURCC identifiers. A FOURCC is a 32-bit quantity representing a sequence of one to four ASCII alphanumeric characters (padded on the right with blank characters). For more information on CODEC procedures, see CODEC Procedures.
