wait_clock
Description:
This function will block until time is reached.
It is usually called by subclasses that use their own internal synchronisation.
If time is not valid, no synchronisation is done and
BADTIME is returned. Likewise, if synchronisation is disabled in the element or there is no clock, no synchronisation is done and
BADTIME is returned.
This function should only be called with the PREROLL_LOCK held, like when receiving an EOS event in the GstBaseSinkClass::event
vmethod or when receiving a buffer in the GstBaseSinkClass::render vmethod.
The time argument should be the running_time of when this method should return and is not adjusted with any latency or offset
configured in the sink.
Parameters:
| this |
the sink |
| time |
the running_time to be reached |
| jitter |
the jitter to be filled with time diff, or |
