The different types of QoS events that can be given to the
gst_event_new_qos() method.
GST_QOS_TYPE_OVERFLOW
The QoS event type that is produced when downstream
elements are producing data too quickly and the element can't keep up
processing the data. Upstream should reduce their processing rate. This
type is also used when buffers arrive early or in time.
GST_QOS_TYPE_UNDERFLOW
The QoS event type that is produced when downstream
elements are producing data too slowly and need to speed up their processing
rate.
GST_QOS_TYPE_THROTTLE
The QoS event type that is produced when the
application enabled throttling to limit the datarate.
