Original commit message from CVS:
2005-02-21 Andy Wingo <wingo@pobox.com>
* gst/gstmessage.h (GstMessageType): Turned into flags. Added
GST_MESSAGE_ANY as an OR of all flags.
(GST_MESSAGE_PARSE_STATE_CHANGED): New terrible macro. Will be
made into a function soon.
(GstMessage): Add a state_changed structure to the union. The
union will die soon in favor of a single GstStructure tho.
(gst_message_new_state_changed): New API.
* gst/gstmessage.c (gst_message_new_state_changed): New API.
* tools/gst-launch.c (check_intr): Set the state of the pipeline
to PAUSED here; the poll will catch the state change.
(event_loop): New function, polls the pipeline bus for events. Can
block until eos/error/state change, or just handle the pending
events.
(main): Changed to use event_loop instead of running a main loop.
* gst/gstbus.h (gst_bus_poll): Added.
(gst_bus_peek): Return non-const; the message is refcounted
anyway.
* gst/gstbus.c (gst_bus_init): Replace the GAsyncQueue with a
GQueue+mutex to allow for _peek. (The wake-up functionality
provided by GAsyncQueue is already done by our socketpair.) All
queue users changed to lock, operate, and unlock.
(gst_bus_post): Check the retval of write(2) and handle errno.
(gst_bus_peek): Implemented.
(gst_bus_pop, gst_bus_peek, bus_callback): Because the socketpair
is used to wake up the GSource, read off the character in the
GSource handler and not in pop/peek. This is because a peek will
require a pop in the future, and you can't read off the char
twice. Deal with errno in the read.
(bus_callback): Interpret the handler return value as whether or
not to pop the message from the bus.
(poll_handler, poll_timeout, gst_bus_poll): New API. gst_bus_poll
is meant to replace the while(gst_bin_iterate()) idiom.
Original commit message from CVS:
Clock fixes. Added async callbacks and clock unscheduling.
Threading fixes. Fixed race condition in GstTask and possible
deadlock in _pad_get_caps(). Made various subsystems (query,
format,..) threadsafe.
Lots of cleanups and documentation.
