gst/playback/gstplaybasebin.*: Don't use a 0 low watermark when buffering, it is catching starvation way too late. In...
Original commit message from CVS: * gst/playback/gstplaybasebin.c: (gst_play_base_bin_class_init), (gst_play_base_bin_init), (fill_buffer), (check_queue), (queue_threshold_reached), (gst_play_base_bin_set_property), (gst_play_base_bin_get_property): * gst/playback/gstplaybasebin.h: Don't use a 0 low watermark when buffering, it is catching starvation way too late. Instead, use a 3 second queue with 30 and 95 percent low/high watermarks. Added queue-min-threshold property to configure low watermark. Use new _buffering message API. Make queue_threshold variable big enough to store a uint64 time value. API: playbin::queue-min-threshold property.
