Original commit message from CVS: * docs/gst/gstreamer-sections.txt: Add new element field and method. * gst/gstbin.c: (gst_bin_class_init), (gst_bin_init), (bin_remove_messages), (gst_bin_add_func), (gst_bin_remove_func), (gst_bin_recalc_state), (gst_bin_get_state_func), (gst_bin_element_set_state), (gst_bin_change_state_func), (gst_bin_continue_func), (bin_bus_handler), (bin_push_state_continue), (bin_handle_async_start), (bin_handle_async_done), (gst_bin_handle_message_func): Make async state changes a bit smarter by using new ASYNC_START and ASYNC_DONE messages. This reduces the number of times we run the state recalculation thread. Don't change state of element with a pending ASYNC_START message. Deprecate STATE_DIRTY messages. * gst/gstelement.c: (gst_element_init), (gst_element_send_event), (gst_element_get_state_func), (gst_element_continue_state), (gst_element_lost_state), (gst_element_set_state_func), (gst_element_change_state): * gst/gstelement.h: Keep the state that was last set by the app in a new element field. Don't allow state changes when handling an element event. Post ASYNC_START and ASYNC_DONE messages. Change lost_state so that we go to PAUSED and wait for the parent to set us to PLAYING again (so latency calculation can be performed) Export gst_element_change_state() method so that subclasses can use it. API: gst_element_change_state() API: GST_STATE_TARGET * gst/gstpipeline.c: (gst_pipeline_class_init), (reset_stream_time), (gst_pipeline_change_state), (gst_pipeline_handle_message), (gst_pipeline_set_new_stream_time): Using the new ASYNC_START message we can reset the base_time when needed. This can then be used to implement base_time redistribution in flushing seeks so that we can remove the explicit seek handling. Perform latency query and configuration when going to PLAYING. * libs/gst/base/gstbasesink.c: (gst_base_sink_commit_state), (gst_base_sink_query), (gst_base_sink_change_state): Post new ASYNC_START/ASYNC_DONE messages. * tests/check/generic/sinks.c: (GST_START_TEST): Fix test because the bin will not set the async element to PLAYING right away. * tests/check/gst/gstbin.c: (pop_async_done), (GST_START_TEST): Make the message check a little stronger. Handle ASYNC messages. * tests/check/pipelines/cleanup.c: (GST_START_TEST): * tests/check/pipelines/simple-launch-lines.c: (GST_START_TEST): Expect ASYNC_DONE messages.
