Adding a buffer to the end of a GstBufferList is supposed to be a fast operation, but it was not since the iterator does not advance its nextpointer when adding buffers and GList does not have a tail pointer. Using a GQueue to store the buffers makes it easier to add buffers to the end of the list and this operation will now be much more efficient. Adding an entire GList of buffers using gst_buffer_list_iterator_add_list() will however have to iterate over the list being added to be able to update the tail pointer in the GQueue.
