The IVPNotify2 interface inherits from IVPNotify and is implemented only by the Overlay Mixer filter. This interface enables the Overlay Mixer to communicate with a video port (on a hardware device such as a decoder) that implements IVPConfig.
Applications should never use this interface.
Requirements
Requires Vptype.h, Vpnotify.h.
