Allocates video samples for a video media sink.
The stream sinks on the enhanced video renderer (EVR) expose this interface as a service. To obtain a pointer to the interface, call IMFGetService::GetService using the service identifier MR_VIDEO_ACCELERATION_SERVICE. Custom media sinks can also implement this interface. The Media Session uses this interface to allocate samples for the EVR, unless the upstream decoder supports DirectX Video Acceleration (DXVA).
