IWMVideoMediaProps interface (wmsdkidl.h)

[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 It has been superseded by Source Reader and Sink Writer.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.]

With this interface, the application can specify additional video-specific parameters not available on the IWMMediaProps interface.

To get access to the methods of this interface, call QueryInterface on a stream configuration object. For more information, see IWMStreamConfig Interface).
