Sets the type of video memory for uncompressed video surfaces. This interface is used by video decoders and transforms.
The DirectShow enhanced video renderer (EVR) filter exposes this interface as a service on the filter's input pins. To obtain a pointer to this interface, call IMFGetService::GetService with the service identifier MR_VIDEO_ACCELERATION_SERVICE.
A video decoder can use this interface to enumerate the EVR filter's preferred surface types and then select the surface type. The decoder should then create surfaces of that type to hold the results of the decoding operation.
This interface does not define a way to clear the surface type. In the case of DirectShow, disconnecting two filters invalidates the surface type.
The IDirectXVideoMemoryConfiguration interface inherits from the IUnknown interface. IDirectXVideoMemoryConfiguration also has these types of members:
