Remarks
This interface is exposed by the Direct3D Device Manager. To create the Direct3D device manager, call DXVA2CreateDirect3DDeviceManager9.
To get this interface from the Enhanced Video Renderer (EVR), call IMFGetService::GetService. The service GUID is MR_VIDEO_ACCELERATION_SERVICE. For the DirectShow EVR filter, call GetService on the filter's pins.
The Direct3D Device Manager supports Direct3D 9 devices only. It does not support DXGI devices.
Windows Store apps must use IMFDXGIDeviceManager and Direct3D 11 Video APIs.
