Major Media Types / Subtypes

​
Major Media Types

In a media type, the major type describes the overall category of the data, such as audio or video. The subtype, if present, further refines the major type. For example, if the major type is video, the subtype might be 32-bit RGB video. Subtypes also distinguish encoded formats, such as H.264 video, from uncompressed formats. Major type and subtype are identified by strings and stored in the following properties: You can use the following major types:

​
Audio Subtypes

The following audio subtype strings are defined. To specify the subtype, set the Subtype property on the media type. When these subtypes are used, set the MajorType property to MediaType_Audio.

​
Stream Subtypes

The following stream subtype strings are defined. To specify the subtype, set the Subtype property on the media type. When these subtypes are used, set the MajorType property to MediaType_Stream.

Notes Reading samples from an MPEG2-transport/program stream is not (yet) possible by use of a Media Source Reader created by MediaCreateSourceReaderFromUrl since Windows does not provide an appropriate Media Source. For obtaining samples from a file containing MPEG2-transport/program stream data you can use the File Functions in CAPL.
