The SetContentId method sets the DRM content ID and its assigned DRM content rights on a KS audio stream.
Specifies the DRM content ID. This parameter is an identifier that the DRM system generates at run time to identify DRM-protected content in this stream.
Pointer to a DRMRIGHTS structure specifying the rights granted by the content provider to the user for playing and copying DRM-protected content in this stream.
SetContentId returns STATUS_SUCCESS if the call was successful. Otherwise, the method returns an appropriate error code. If the filter cannot enforce the specified content rights, the method returns STATUS_NOT_IMPLEMENTED.
The DRM system can call the SetContentId method at any time during the lifetime of a KS audio stream.
A KS audio filter completes the execution of a call to the SetContentId method synchronously. If the function returns STATUS_SUCCESS, this indicates that all the downstream KS audio nodes (see Audio Topology Nodes) of a KS audio stream have also been successfully configured with the specified DRM content ID and DRM content rights. (The term downstream node refers to either a direct or an indirect sink for an audio stream.)
If the KS audio filter cannot enforce the specified DRM content rights, the SetContentId method returns the error code STATUS_NOT_IMPLEMENTED. In this case, the KS audio stream's previously set DRM content ID and DRM content rights remain set on the stream.
