The 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.
In addition to the methods inherited from IUnknown, the IVMRImagePresenter interface exposes the following methods.
IVMRImagePresenter Methods | Description |
PresentImage | Called at precisely the moment this video frame should be presented. |
StartPresenting | Called just before the video starts playing. |
StopPresenting | Called just after the video stops playing. |
