IVMRSurfaceAllocator9::AdviseNotify method (vmr9.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 AdviseNotify method provides the allocator-presenter with the VMR-9 filter's interface for notification callbacks. If you are using a custom allocator-presenter, the application must call this method on the allocator-presenter, with a pointer to the VMR's IVMRSurfaceAllocatorNotify9 interface. The allocator-presenter uses this interface to communicate with the VMR.

If you are not using a custom allocator-presenter, the application does not have to call this method.
