WMT_COLORSPACEINFO_EXTENSION_DATA structure (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 It has been superseded by Source Reader and Sink Writer.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.]
The WMT_COLORSPACEINFO_EXTENSION_DATA structure contains information about the color format of output video samples. It is used as the value for the WM_SampleExtensionGUID_ColorSpaceInfo data unit extension.
Syntax
