Detailed Description

A latency event.

See create() for more details.

Member Function Documentation

static Glib::RefPtr<Gst::EventLatency> Gst::EventLatency::create ( ClockTime  latency)
static

Create a new latency event.

The event is sent upstream from the sinks and notifies elements that they should add an additional latency to the timestamps before synchronising against the clock.

The latency is mostly used in live sinks and is always expressed in the time format.

Parameters
latencyThe new latency value.
Returns
A new Gst::EventLatency.

Since 0.10.12.

ClockTime Gst::EventLatency::parse ( ) const

Get the latency in the latency event.

Returns
The latency.
