IVMRSurfaceAllocator9 Interface

IVMRSurfaceAllocator9 Interface
The IVMRSurfaceAllocator9 interface is implemented by the default allocator-presenter for the Video Mixing Renderer Filter 9 (VMR-9). It must also be implemented by any plug-in allocator-presenter object that an application provides to the VMR-9. The VMR-9 uses the methods on this interface to allocate, prepare and free Direct3D surfaces. Applications do not use this interface.
In addition to the methods inherited from IUnknown, the IVMRSurfaceAllocator9 interface exposes the following methods.
| Method | Description |
| AdviseNotify | Provides the allocator-presenter with the VMR-9 filter's interface for notification callbacks. |
| GetSurface | Retrieves a Direct3D surface. |
| InitializeDevice | Called by the VMR-9 when it needs the allocator-presenter to allocate surfaces. |
| TerminateDevice | Releases the Direct3D device. |
