IVMRImagePresenter interface (strmif.h)
IVMRImagePresenter interface is implemented by the default Allocator-Presenter for the Video Mixing Renderer Filter 7 (VMR-7). It must also be implemented by any plug-in Allocator-Presenter that an application provides for the VMR-7. The VMR-7 uses the methods on this interface to inform the Allocator-Presenter that it should present the video frame contained in the supplied Direct Draw surface. Applications do not use this interface.
For the VMR-9, use the IVMRImagePresenter9 interface.
The IVMRImagePresenter interface inherits from the IUnknown interface. IVMRImagePresenter also has these types of members:
The IVMRImagePresenter interface has these methods.
|IVMRImagePresenter::PresentImage||The PresentImage method is called at precisely the moment this video frame should be presented.|
|IVMRImagePresenter::StartPresenting||The StartPresenting method is called just before the video starts playing. The allocator-presenter should perform any necessary configuration in this method.|
|IVMRImagePresenter::StopPresenting||The StopPresenting method is called just after the video stops playing. The allocator-presenter should perform any necessary cleanup in this method.|
