IWMDRMReader 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 It has been superseded by Source Reader and Sink Writer.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.]
[IWMDRMReader is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions. Instead, use Microsoft PlayReady. ]
The IWMDRMReader interface provides methods to configure the DRM component and to manage DRM license acquisition and individualization of client applications. It is used only for content protected using DRM version 7, not the earlier DRM version 1.
This interface can be obtained from a reader object.
