Thanks for your reply. Is there a way to decide buffer allocator between an output port and an input port in node level? Now what i see is opencore always take the upstream output port as the supplier for the buffer shared in a connection , and use a flag PVMF_MIME_YUV420_SEMIPLANAR_YVU in iVideoSubFormat to indicate whether upstream node is a hardware codec. If it is a hardware codec, the surface can directly take use of the buffer pass down for rendering.
Why not take use of useMemoryAllocators in opencore, and let 3rd party implement their own allcator, and hook them to node as they wanted? If so opencore will not care where the buffer come from, just take and use it.
