IVMRWindowlessControl9 Interface

The IVMRWindowlessControl9 interface controls how the Video Mixing Renderer Filter 9 (VMR-9) renders a video stream within a container window. Applications must first put the VMR-9 into windowless mode before using the methods on this interface.

In addition to the methods inherited from IUnknown, the IVMRWindowlessControl9 interface exposes the following methods.
