public class Event
extends MiniObject

Base type of all events.

See upstream documentation at https://gstreamer.freedesktop.org/data/doc/gstreamer/stable/gstreamer/html/GstEvent.html

Events are passed between elements in parallel to the data stream. Some events are serialized with buffers, others are not. Some events only travel downstream, others only upstream. Some events can travel both upstream and downstream.

The events are used to signal special conditions in the datastream such as EOS (end of stream) or the start of a new stream-segment.

Events are also used to flush the pipeline of any pending data.
