|
|
|
* GStreamer uses a global clock to synchronize the plugins in a pipeline.
|
2005-08-27 10:57:00 +00:00
|
|
|
* Different clock implementations are possible by implementing this abstract
|
|
|
|
* base class.
|
|
|
|
*
|
2005-10-28 17:35:05 +00:00
|
|
|
* The #GstClock returns a monotonically increasing time with the method
|
|
|
|
* gst_clock_get_time(). Its accuracy and base time depends on the specific clock
|
|
|
|
* implementation but time is always expessed in nanoseconds. Since the
|
|
|
|
* baseline of the clock is undefined, the clock time returned is not
|
|
|
|
* meaningfull in itself, what matters are the deltas between two clock
|
|
|
|
* times.
|
|
|
|
*
|
|
|
|
* The pipeline uses the clock to calculate the stream time.
|
|
|
|
* Usually all renderers synchronize to the global clock using the buffer timestamps,

|
|
* The time of the clock in itself is not very useful for an application.
|
2005-10-28 17:35:05 +00:00
|
|
|
*
|
|
|
|
* A clock implementation can support periodic and single shot clock notifications
|
|
|
|
* both synchronous and asynchronous.
|
|
|
|
*
|
|
|
|
* One first needs to create a #GstClockID for the periodic or single shot
|
|
|
|
* notification using gst_clock_new_single_shot_id() or gst_clock_new_periodic_id().
|
|
|
|
*
|
|
|
|
* To perform a blocking wait for the specific time of the #GstClockID use the
|
|
|
|
* gst_clock_id_wait(). To receive a callback when the specific time is reached
|
|
|
|
* in the clock use gst_clock_id_wait_async(). Both these calls can be interrupted
|
|
|
|
* with the gst_clock_id_unschedule() call. If the blocking wait is unscheduled
|
|
|
|
* a return value of GST_CLOCK_UNSCHEDULED is returned.
|
|
|
|
*
|
2005-11-09 12:36:17 +00:00
|
|
|
* Periodic callbacks scheduled async will be repeadedly called automatically until
|
|
|
|
* it is unscheduled. To schedule an async periodic callback, gst_clock_id_wait()
|
|
|
|
* should be called repeadedly.
|
|
|
|
*
|
2005-10-28 17:35:05 +00:00
|
|
|
* The async callbacks can happen from any thread, either provided by the
|
|
|
|
* core or from a streaming thread. The application should be prepared for this.
|
|
|
|
*
|
|
|
|
* A #GstClockID that has been unscheduled cannot be used again for any wait
|
|
|
|
* operation.
|
|
|
|
*
|
|
|
|
* It is possible to perform a blocking wait on the same #GstClockID from multiple
|
|
|
|
* threads. However, registering the same #GstClockID for multiple async notifications is
|
|
|
|
* not possible, the callback will only be called once.
|
|
|
|
*
|
|
|
|
* None of the wait operations unref the #GstClockID, the owner is
|
|
|
|
* responsible for unreffing the ids itself. This holds for both periodic and
|
|
|
|
* single shot notifications. The reason being that the owner of the #GstClockID
|
|
|
|
* has to keep a handle to the #GstClockID to unblock the wait on FLUSHING events
|
|
|
|
* or state changes and if we unref it automatically, the handle might be
|
|
|
|
* invalid.
|
|
|
|
*
|
|
|
|
* These clock operations do not operate on the stream time, so the callbacks
|
|
|
|
* will also occur when not in PLAYING state as if the clock just keeps on
|
|
|
|
* running. Some clocks however do not progress when the element that provided
|
|
|
|
* the clock is not PLAYING.

Implement master/slave. When setting a clock as a slave, a
periodic timeout is scheduled to sample master and slave times.
Then the slave clock is recalibrated to match offset and rate
of the master clock.
Update logging a bit.
Add flag so that a clock can state that is cannot be slaved to
another clock.

The set_clock returns a gboolean for when an element cannot

Implement master/slave. When setting a clock as a slave, a
periodic timeout is scheduled to sample master and slave times.
Then the slave clock is recalibrated to match offset and rate
of the master clock.
Update logging a bit.
Add flag so that a clock can state that is cannot be slaved to
another clock.

The set_clock returns a gboolean for when an element cannot
deal with the selected clock in the pipeline.

gst/gstclock.*: deprecate old interface and disable functions that aren't in use anymore.
Original commit message from CVS:
2004-01-13 Benjamin Otte <in7y118@public.uni-hamburg.de>
* gst/gstclock.c: (gst_clock_class_init), (gst_clock_init),
(gst_clock_set_speed), (gst_clock_set_active),
(gst_clock_is_active), (gst_clock_reset),
(gst_clock_handle_discont):
* gst/gstclock.h:
deprecate old interface and disable functions that aren't in use
anymore.
* gst/gstelement.h:
* gst/gstelement.c: (gst_element_get_time), (gst_element_wait),
(gst_element_set_time), (gst_element_adjust_time):
add concept of "element time" and functions to get/set this time.
* gst/gstelement.c: (gst_element_change_state):
update element time correctly.
* gst/gstelement.c: (gst_element_get_compatible_pad_filtered):
This is a debug message, not a g_critical.
* gst/gstpad.c: (gst_pad_event_default):
handle discontinuous events right with element time.
* gst/gstscheduler.c: (gst_scheduler_state_transition):
update to clocking fixes.
set clocks on elements in READY=>PAUSED. The old behaviour caused
a wrong element time on the first element that started playing.
* gst/schedulers/gstbasicscheduler.c:
(gst_basic_scheduler_class_init):
* gst/schedulers/gstoptimalscheduler.c:
(gst_opt_scheduler_class_init):
remove code that just implements the default behaviour.
* gst/elements/gstfakesink.c: (gst_fakesink_chain):
update to use new clocking functions
* testsuite/clock/clock1.c: (gst_clock_debug), (main):
* testsuite/clock/clock2.c: (gst_clock_debug), (main):
update to test new element time.
* gst/autoplug/gstspideridentity.c: (gst_spider_identity_getcaps):
use _get_allowed_caps instead of _get_caps. This catches filtered
caps correctly.
* testsuite/debug/commandline.c:
update for new GST_DEBUG syntax.
* testsuite/threads/Makefile.am:
disable a test that only works sometimes.
