Browse source 
Original commit message from CVS:
* libs/gst/base/gstbasesink.c: (gst_base_sink_do_sync),
(gst_base_sink_render_object),
(gst_base_sink_queue_object_unlocked):
Only keep track of prerollable items when we are
prerolling.
Before rendering after preroll, always check if we
have queued items.
Added some more debugging.
