Original commit message from CVS: * docs/design/draft-latency.txt: Small update. * docs/libs/gstreamer-libs-sections.txt: * libs/gst/base/gstbasesink.c: (gst_base_sink_class_init), (gst_base_sink_get_latency), (gst_base_sink_query_latency), (gst_base_sink_wait_clock), (gst_base_sink_send_qos), (gst_base_sink_perform_qos), (gst_base_sink_queue_object_unlocked), (gst_base_sink_chain_unlocked), (gst_base_sink_send_event), (gst_base_sink_get_position), (gst_base_sink_query), (gst_base_sink_change_state): * libs/gst/base/gstbasesink.h: API: gst_base_sink_query_latency() to let subclasses query the upstream latency. API: gst_base_sink_get_latency() to let subclasses query the configured latency in the sink. Implement query and set latency. Update some docs. As spotted by Will Newton <will dot newton at gmail dot com>: Make sure we don't continue preroll when we are flushing. Fixes #405284. * tests/check/pipelines/stress.c: (change_state_timeout), (quit_timeout), (GST_START_TEST), (stress_suite): Test for #405284.
