IVPNotify2 interface (vpnotify.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 IVPNotify2 interface inherits from IVPNotify and is implemented 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.
