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 #GstFlowReturn value.
