IMediaSample2Config interface (strmif.h)
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The IMediaSample2Config interface returns a pointer to a Direct3D surface representing a VRAM capture buffer.

Remarks
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).
