The IVMRVideoStreamControl9 interface is implemented on each input pin of the Video Mixing Renderer Filter 9. The interface operates on the input stream represented by the pin. This interface is used by upstream filters (typically decoders) to get or set the active state of individual streams. Applications in general should not use this interface.
In addition to the methods inherited from IUnknown, the IVMRVideoStreamControl9 interface exposes the following methods:
|GetStreamActiveState||Retrieves the state of the stream.|
|SetStreamActiveState||Activates or inactivates an input stream.|
