gst/gstqueue.c (gst_queue_init, gst_queue_link_sink)
Original commit message from CVS: 2004-11-23 Martin Soto <martinsoto@users.sourceforge.net> * gst/gstqueue.c (gst_queue_init, gst_queue_link_sink) (gst_queue_link_src): Allow for renegotiating the caps of the sink pad. The queue will now wait until it is empty and forward the new caps to the source. * gst/gstbin.c (gst_bin_set_element_sched) (gst_bin_unset_element_sched): Make sure that all elements and links are registered and unregistered with the scheduler exactly once. This elaborates on a fix by Benjamin Otte, but guarantees that decoupled elements are also registered.
