ObjectWrap.getControlRate
gst.types.ClockTime getControlRate()Obtain the control-rate for this object. Audio processing #GstElement objects will use this rate to sub-divide their processing loop and call gst.object.ObjectWrap.syncValues in between. The length of the processing segment should be up to control-rate nanoseconds.
If the object is not under property control, this will return gst.types.CLOCK_TIME_NONE. This allows the element to avoid the sub-dividing.
The control-rate is not expected to change if the element is in gst.types.State.Paused or gst.types.State.Playing.
Returns
the control rate in nanoseconds
