VMR9PresentationFlags enumeration (vmr9.h)

  • [アーティクル]

[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 VMR9PresentationFlags enumeration type contains flags that describe the status of a video sample. These flags are used in the VMR9PresentationInfo structure.

  VMR9Sample_Discontinuity = 0x4,
  VMR9Sample_TimeValid = 0x8,
  VMR9Sample_SrcDstRectsValid = 0x10
} VMR9PresentationFlags;
