The IMemAllocatorCallbackTemp interface enables a filter to receive a callback notification from an allocator whenever a sample is returned to the allocator's free list.
The use of this interface is deprecated.
In addition to the methods inherited from IMemAllocator, the IMemAllocatorCallbackTemp interface exposes the following methods.
|GetFreeCount||Retrieves the number of free media samples.|
|SetNotify||Sets or removes a callback on the allocator.|
