Gst.Message.new_qos

function new_qos(src:Gst.Object, live:Boolean, running_time:Number, stream_time:Number, timestamp:Number, duration:Number):Gst.Message {
    // Gjs wrapper for gst_message_new_qos()
}

A QOS message is posted on the bus whenever an element decides to drop a buffer because of QoS reasons or whenever it changes its processing strategy because of QoS reasons (quality adjustments such as processing at lower accuracy).

This message can be posted by an element that performs synchronisation against the clock (live) or it could be dropped by an element that performs QoS because of QOS events received from a downstream element (!live).

running_time, stream_time, timestamp, duration should be set to the respective running-time, stream-time, timestamp and duration of the (dropped) buffer that generated the QoS event. Values can be left to GST_CLOCK_TIME_NONE when unknown.

src: The object originating the message.
live: if the message was generated by a live element
running_time: the running time of the buffer that generated the message
stream_time: the stream time of the buffer that generated the message
timestamp: the timestamps of the buffer that generated the message
duration: the duration of the buffer that generated the message
Returns: The new qos message. MT safe.
