IMemInputPin interface
The IMemInputPin interface delivers media data to an input pin. Input pins expose this interface if they use the IMemAllocator interface to allocate buffers. When an output pin connects to an input pin, the output pin uses this interface to negotiate allocator requirements and deliver samples to the input pin.
Applications typically do not use this interface.
Filter developers: The CBaseInputPin class implements this interface.
Members
The IMemInputPin interface inherits from the IUnknown interface. IMemInputPin also has these types of members:
