VMR9PresentationInfo structure (vmr9.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 VMR9PresentationInfo structure is used with the VMR-9 in the IVMRImagePresenter9::PresentImage method.

  SIZE              szAspectRatio;
  RECT              rcSrc;
  RECT              rcDst;
  DWORD             dwReserved1;
  DWORD             dwReserved2;
} VMR9PresentationInfo;
