DRM_LicenseID
[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 It has been superseded by Source Reader and Sink Writer.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_LicenseID property contains a string retrieved from the license associated with the currently open file that uniquely identifies that license.
Global Constant
g_wszWMDRM_LicenseID
Data Type
WMT_TYPE_STRING
Remarks
This attribute is present with DRM Version 7 content only. It can be set using IWMDRMWriter::SetDRMAttribute and it can be retrieved with IWMDRMReader::GetDRMProperty.
The license ID is stored in a license, not in an ASF file. Each individual license has a unique ID which is assigned by the license generator at the time the license is created. For example, if you obtain two licenses for the same content, each one will have a different LicenseID attribute. Typically, applications have no need to retrieve this value.
