Gst.Message.prototype.set_qos_stats

function set_qos_stats(format:Gst.Format, processed:Number, dropped:Number):void {
    // Gjs wrapper for gst_message_set_qos_stats()
}

Set the QoS stats representing the history of the current continuous pipeline playback period.

When format is @GST_FORMAT_UNDEFINED both dropped and processed are invalid. Values of -1 for either processed or dropped mean unknown values.

MT safe.

format: Units of the 'processed' and 'dropped' fields. Video sinks and video filters will use GST_FORMAT_BUFFERS (frames). Audio sinks and audio filters will likely use GST_FORMAT_DEFAULT (samples).
processed: Total number of units correctly processed since the last state change to READY or a flushing operation.
dropped: Total number of units dropped since the last state change to READY or a flushing operation.
