DRM_Level
[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 It has been superseded by Source Reader and Sink Writer.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.]
DRM_Level is a license attribute that the Windows Media Format SDK sets when it creates a local license for files protected with DRM version 1. It contains the security level that the calling application must have to access the content in the file. The default value is 150.

Remarks
An application's DRM security level is determined by the particular wmstubdrm library that it links to at compile time. For more information on these security levels, see Obtaining the Required DRM Library. Use IWMHeaderInfo::SetAttribute to set this property when protecting ASF files with DRM version 1.
