IVPBaseNotify 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
