DRM_MINIMUM_OUTPUT_PROTECTION_LEVELS 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 It has been superseded by Source Reader and Sink Writer.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 DRM_MINIMUM_OUTPUT_PROTECTION_LEVELS structure holds the minimum output protection levels (OPL) for playback of various types of content. A device must support the minimum OPL for a type of data to receive that type of data from the reader.
