The IVMRImageCompositor interface is implemented by the default compositor for the Video Mixing Renderer Filter 7 (VMR-7). It must also be implemented by any plug-in compositor that an application provides for the VMR-7. The VMR07 calls the methods on this interface to inform the Compositor that it should composite the incoming video frames into a single output frame. Applications do not use this interface.
For the VMR-9, use the IVMRImageCompositor9 interface.
In addition to the methods inherited from IUnknown, the IVMRImageCompositor interface exposes the following methods.
|CompositeImage||Composites the current frames available in each input stream.|
|InitCompositionTarget||Informs the compositor that a new composition target has been created.|
|SetStreamMediaType||Sets the media type for the input stream.|
|TermCompositionTarget||Informs the compositor that the current composition target is being replaced.|
