A function that will be called on sinkpads when chaining buffer lists.
The function typically processes the data contained in the buffer list and either consumes the data or passes it on to the internally linked pad(s).
The implementer of this function receives a refcount to list
and should gst_buffer_list_unref
when the list is
no longer needed.
When a chainlist function detects an error in the data stream, it must post an error on the bus and return an appropriate FlowReturn value.
