Description
The GStreamer core provides a GstSystemClock based on the system time. Asynchronous callbacks are scheduled from an internal thread.
Clock implementors are encouraged to subclass this systemclock as it implements the async notification.
Subclasses can however override all of the important methods for sync and async notifications to implement their own callback methods or blocking wait operations.
Functions
gst_system_clock_obtain ()
GstClock *
gst_system_clock_obtain (void);
Get a handle to the default system clock. The refcount of the clock will be increased so you need to unref the clock after usage.
gst_system_clock_set_default ()
void
gst_system_clock_set_default (GstClock *new_clock);
Sets the default system clock that can be obtained with
gst_system_clock_obtain().
This is mostly used for testing and debugging purposes when you want to have control over the time reported by the default system clock.
MT safe.
Since: 1.4
