/**
* SECTION:gstclock
* @short_description: Abstract class for global clocks
* @see_also: #GstSystemClock, #GstPipeline
*
* GStreamer uses a global clock to synchronize the plugins in a pipeline.
* Different clock implementations are possible by implementing this abstract
* base class or, more conveniently, by subclassing #GstSystemClock.
*
* The #GstClock returns a monotonically increasing time with the method
* gst_clock_get_time(). Its accuracy and base time depend on the specific
* clock implementation but time is always expressed in nanoseconds. Since the
* baseline of the clock is undefined, the clock time returned is not
* meaningful in itself, what matters are the deltas between two clock times.
* The time returned by a clock is called the absolute time.
*
* The pipeline uses the clock to calculate the running time. Usually all
* renderers synchronize to the global clock using the buffer timestamps, the
* newsegment events and the element's base time, see #GstPipeline.
*
* 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
2009-04-08 15:13:42 +00:00
* unscheduled a return value of #GST_CLOCK_UNSCHEDULED is returned.
*
* Periodic callbacks scheduled async will be repeatedly called automatically
* until it is unscheduled. To schedule a sync periodic callback,
* gst_clock_id_wait() should be called repeatedly.
*
* 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, a new #GstClockID should be created and the old unscheduled one
* should be destroyed with gst_clock_id_unref().
*
* 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 for
* the thread registering the entry last.
*
* 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 the entry would be unreffed automatically, the handle
* might become invalid without any notification.
*
* These clock operations do not operate on the running 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.
*
* When a clock has the #GST_CLOCK_FLAG_CAN_SET_MASTER flag set, it can be
* slaved to another #GstClock with the gst_clock_set_master(). The clock will
* then automatically be synchronized to this master clock by repeatedly
* sampling the master clock and the slave clock and recalibrating the slave
* clock with gst_clock_set_calibration(). This feature is mostly useful for
* plugins that have an internal clock but must operate with another clock
* selected by the #GstPipeline. They can track the offset and rate difference
* of their internal clock relative to the master clock by using the
* gst_clock_get_calibration() function.
*
2009-04-08 15:13:42 +00:00
* The master/slave synchronisation can be tuned with the #GstClock:timeout,
* #GstClock:window-size and #GstClock:window-threshold properties.
* The #GstClock:timeout property defines the interval to sample the master
* clock and run the calibration functions. #GstClock:window-size defines the
* number of samples to use when calibrating and #GstClock:window-threshold
* defines the minimum number of samples before the calibration is performed.

* Adjusts the rate and time of @clock. A rate of 1/1 is the normal speed of
* the clock. Values bigger than 1/1 make the clock go faster.
*
* @internal and @external are calibration parameters that arrange that
* gst_clock_get_time() should have been @external at internal time @internal.
* This internal time should not be in the future; that is, it should be less
* than the value of gst_clock_get_internal_time() when this function is called.
*
* Subsequent calls to gst_clock_get_time() will return clock times computed as
* follows:
*
* <programlisting>
* time = (internal_time - internal) * rate_num / rate_denom + external

Add flag so that a clock can state that is cannot be slaved to another clock. * gst/gstelement.c: (gst_element_set_clock): * gst/gstelement.h: The set_clock returns a gboolean for when an element cannot deal with the selected clock in the pipeline. * gst/gstpipeline.c: (gst_pipeline_change_state), (gst_pipeline_set_clock): * gst/gstpipeline.h: Handle the case where the selected clock cannot be set on the pipeline. * gst/net/gstnetclientclock.c: (gst_net_client_clock_class_init), (gst_net_client_clock_init), (gst_net_client_clock_finalize), (gst_net_client_clock_set_property), (gst_net_client_clock_get_property), (gst_net_client_clock_observe_times): * gst/net/gstnetclientclock.h: Use regression code in GstClock parent, remove duplicated functionality.
