Analog Video Crossbar Filter

The Analog Video Crossbar filter represents a video crossbar on a video capture device that supports the Windows Driver Model (WDM).

This filter is a wrapper filter for crossbars on WDM streaming devices. The filter's friendly name is taken from the device. Each output pin represents a hardware path for analog baseband video. One of the input pins comes from a TV Tuner (the TV Tuner Filter). Other input pins support video or audio streams. The filter supports any media subtypes and formats that are supported on the downstream connections.

You cannot directly create this filter with CoCreateInstance. The ICaptureGraphBuilder2 interface automatically adds this filter to the graph as needed.
