[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 IVMRSurfaceAllocatorNotify interface is implemented by the Video Mixing Renderer Filter 7 (VMR-7). Applications use this interface to set a custom allocator-presenter and the allocator-presenter uses this interface to inform the VMR-7 of changes to the system environment that affect the DirectDraw surfaces.
In order for an application to obtain this interface, the VMR must be in renderless mode.
For the VMR-9, use the IVMRSurfaceAllocatorNotify9 interface.
The IVMRSurfaceAllocatorNotify interface inherits from the IUnknown interface. IVMRSurfaceAllocatorNotify also has these types of members:
