Requirements
If a display driver supports VRAM capture, the KsProxy filter allocates samples that expose this interface. Downstream filters can use this interface to access the video data in video memory, without requiring the data to be copied into system memory. The display driver must support the Windows Vista Display Driver Model (WDDM).
Requirements
Header: Declared in Strmif.h; include Dshow.h.
Library: Use Strmiids.lib.
