VMRPRESENTATIONINFO structure (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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 VMRPRESENTATIONINFO structure is used in the IVMRImagePresenter::PresentImage method (VMR-7 only).

Members
dwFlags
A bitwise combination of flags from the VMRPresentationFlags enumeration, which describe the status of the video sample with respect to its presentation time.
lpSurf

rcSrc
The source rectangle.
rcDst
