Wim Taymans d14c4c4a67 docs/gst/gstreamer-sections.txt: Add new element field and method.
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.
