<p>Allocate a new qos event with the given values. </p>
<p>The QOS event is generated in an element that wants an upstream element to either reduce or increase its rate because of high/low CPU load or other resource usage such as network performance or throttling. Typically sinks generate these events for each buffer they receive.</p>
<p><em>type</em> indicates the reason for the QoS event. <a class="el" href="namespaceGst.html#ga5b341ba0915502eeb96052307ef0780fadf2734556dc5049c25ff96aa43c54d17" title="The QoS event type that is produced when upstream elements are producing data too quickly and the ele...">Gst::QOS_TYPE_OVERFLOW</a> is used when a buffer arrived in time or when the sink cannot keep up with the upstream datarate. <a class="el" href="namespaceGst.html#ga5b341ba0915502eeb96052307ef0780fa44928c34290bcd30ddc1a89d475eb980" title="The QoS event type that is produced when upstream elements are producing data too slowly and need to ...">Gst::QOS_TYPE_UNDERFLOW</a> is when the sink is not receiving buffers fast enough and thus has to drop late buffers. <a class="el" href="namespaceGst.html#ga5b341ba0915502eeb96052307ef0780fa115a81728f245a3888afe6273d97f3a7" title="The QoS event type that is produced when the application enabled throttling to limit the data rate...">Gst::QOS_TYPE_THROTTLE</a> is used when the datarate is artificially limited by the application, for example to reduce power consumption.</p>
<p><em>proportion</em> indicates the real-time performance of the streaming in the element that generated the QoS event (usually the sink). The value is generally computed based on more long term statistics about the streams timestamps compared to the clock. A value < 1.0 indicates that the upstream element is producing data faster than real-time. A value > 1.0 indicates that the upstream element is not producing data fast enough. 1.0 is the ideal <em>proportion</em> value. The proportion value can safely be used to lower or increase the quality of the element.</p>
<p><em>diff</em> is the difference against the clock in running time of the last buffer that caused the element to generate the QOS event. A negative value means that the buffer with <em>timestamp</em> arrived in time. A positive value indicates how late the buffer with <em>timestamp</em> was. When throttling is enabled, <em>diff</em> will be set to the requested throttling interval.</p>
<p><em>timestamp</em> is the timestamp of the last buffer that cause the element to generate the QOS event. It is expressed in running time and thus an ever increasing value.</p>
<p>The upstream element can use the <em>diff</em> and <em>timestamp</em> values to decide whether to process more buffers. For positive <em>diff</em>, all buffers with timestamp <= <em>timestamp</em> + <em>diff</em> will certainly arrive late in the sink as well. A (negative) <em>diff</em> value so that <em>timestamp</em> + <em>diff</em> would yield a result smaller than 0 is not allowed.</p>
<p>The application can use general event probes to intercept the QoS event and implement custom application specific QoS handling.</p>
