Original commit message from CVS: 2005-03-07 Andy Wingo <wingo@pobox.com> * check/gst/gstobject.c (test_fake_object_name): The object *does* have a name after g_object_new. * gst/base/gstbasesink.c: Change "arguments" to "properties" in the code. Die GtkObject die! (GstBaseSink::preroll-queue-len): New object property, the number of buffers to queue in preroll. By default, does not queue any buffers. Set to a higher number if you have a one-threaded demuxer. (gst_basesink_preroll_queue_push) (gst_basesink_preroll_queue_empty) (gst_basesink_preroll_queue_flush): Implement a queue of buffers for preroll. All must be called with PREROLL_LOCK. (gst_basesink_finish_preroll): Instead of always blocking, push the buffer onto the queue. preroll_queue_push will block if the queue is full. (gst_basesink_event): Make sure the preroll queue is emptied on eos and flushed on flush. (gst_basesink_handle_buffer): Does the work of chain_unlocked, but without going into finish_preroll. (gst_basesink_change_state): Handle setting up the queue and flushing it in READY<->PAUSED transitions.
