IMFPMPHost interface
Enables a media source in the application process to create objects in the protected media path (PMP) process.
Members
The IMFPMPHost interface inherits from the IUnknown interface. IMFPMPHost also has these types of members:
Methods
The IMFPMPHost interface has these methods.
| Method | Description |
|---|---|
| CreateObjectByCLSID |
Creates an object in the PMP process, from a CLSID. |
| LockProcess |
Blocks the PMP process from ending. |
| RemoteCreateObjectByCLSID |
Remotable version of CreateObjectByCLSID. (Not used by applications.) |
| UnlockProcess |
Decrements the lock count on the PMP process. |
Remarks
This interface is used when a media source resides in the application process but the Media Session resides in a PMP process. The media source can use this interface to create objects in the PMP process. For example, to play DRM-protected content, the media source typically must create an input trust authority (ITA) in the PMP process.
To use this interface, the media source implements the IMFPMPClient interface. The PMP Media Session calls IMFPMPClient::SetPMPHost on the media source, passing in a pointer to the IMFPMPHost interface.
You can also get a pointer to this interface by calling IMFGetService::GetService on the PMP Media Session, using the service identifier MF_PMP_SERVICE.
