BaseSink.waitClock

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 [gst.types.ClockReturn.Badtime] is returned. Likewise, if synchronisation is disabled in the element or there is no clock, no synchronisation is done and [gst.types.ClockReturn.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.
