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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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).

Syntax

typedef struct tagVMRPRESENTATIONINFO {
  DWORD                dwFlags;
  LPDIRECTDRAWSURFACE7 lpSurf;
  REFERENCE_TIME       rtStart;
  REFERENCE_TIME       rtEnd;
  SIZE                 szAspectRatio;
  RECT                 rcSrc;
  RECT                 rcDst;
  DWORD                dwTypeSpecificFlags;
  DWORD                dwInterlaceFlags;
} VMRPRESENTATIONINFO;

Members

dwFlags

rtEnd

The end time for the current frame, in 100-nanosecond units.

szAspectRatio

The aspect ratio of the rectangle.

rcSrc

The source rectangle.

rcDst

The destination rectangle.

dwTypeSpecificFlags
