IVMRVideoStreamControl9 interface (vmr9.h)

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

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.
