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.

Methods

The IMemInputPin interface has these methods.

Method Description
IMemInputPin::GetAllocator The GetAllocator method retrieves the memory allocator proposed by this pin. After the allocator has been selected, this method returns a pointer to the selected allocator.
IMemInputPin::GetAllocatorRequirements The GetAllocatorRequirements method retrieves the allocator properties requested by the input pin.
IMemInputPin::NotifyAllocator The NotifyAllocator method specifies an allocator for the connection.
IMemInputPin::Receive The Receive method receives the next media sample in the stream.
IMemInputPin::ReceiveCanBlock The ReceiveCanBlock method determines whether calls to the IMemInputPin::Receive method might block.
IMemInputPin::ReceiveMultiple The ReceiveMultiple method receives multiple samples in the stream.
