IKsNodeControl interface (vidcap.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 IKsNodeControl interface must be implemented by USB Video Class (UVC) extension units. A UVC extension unit is a COM object that provides extended functionality to a USB video device, beyond the functionality provided by the UVC class driver.
The IKsNodeControl interface is used by the KsProxy filter to communicate with the extension unit. Applications do not use this interface. For more information, see the topic "USB Video Class Extension Units" in the Windows DDK.
