IVMRFilterConfig9 interface

The IVMRFilterConfig9 interface is implemented by the Video Mixing Renderer Filter 9. Applications use this interface to configure the VMR's operating mode and video rendering mechanisms. Applications must add the VMR to the graph and configure it before it is connected to any upstream filters (for example, in a call to IGraphBuilder::RenderFile). Once a filter has been connected to the VMR, the VMR's configuration is locked and all future attempts to alter it fail.

Members
