IDirectDrawMediaSampleAllocator::GetDirectDraw method (amstream.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 GetDirectDraw method retrieves a pointer to the DirectDraw instance used to allocate surfaces.

[out] IDirectDraw **ppDirectDraw
);
Parameters

Address of a pointer that receives the DirectDraw object's IDirectDraw interface.
