Media Type Identifiers for the Windows Media Format SDK

[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

You must use media types to define the format of media used with the Windows Media Format SDK. For descriptions of the various media types, see Media Types.

The following table lists the global identifiers for all supported media types and their corresponding GUID values.
