IMSVidCtl Interface

This topic applies to Windows XP or later.

The IMSVidCtl interface is the main interface for the Video Control. It contains methods to enumerate available devices and features, and to select which features and devices will be active. It also contains methods to build, stop, start, and pause the filter graph.
