Aggregator.setLatency

void setLatency(gst.types.ClockTime minLatency, gst.types.ClockTime maxLatency)

Lets #GstAggregator sub-classes tell the baseclass what their internal latency is. Will also post a LATENCY message on the bus so the pipeline can reconfigure its global latency if the values changed.

Parameters

`minLatency`	minimum latency
`maxLatency`	maximum latency
