IVMRSurfaceAllocator::AdviseNotify method (strmif.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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-7 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 IVMRSurfaceAllocatorNotify 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.
Syntax

[in] IVMRSurfaceAllocatorNotify *lpIVMRSurfAllocNotify
);
Parameters
[in] lpIVMRSurfAllocNotify
Specifies the IVMRSurfaceAllocatorNotify interface pointer that the allocator-presenter will use to pass notifications back to the VMR.
Return value
