+<description>
+Allocate a new qos event with the given values.
+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.
+Typically sinks generate these events for each buffer they receive.
+
+ proportion 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 &amp;lt; 1.0 indicates that the upstream element is producing data faster
+than real-time. A value &amp;gt; 1.0 indicates that the upstream element is not
+producing data fast enough. 1.0 is the ideal @proportion value. The
+proportion value can safely be used to lower or increase the quality of
+the element.
+
+ diff 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 @timestamp arrived in time. A positive value
+indicates how late the buffer with @timestamp was.
+
+ timestamp 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.
+
+The upstream element can use the @diff and @timestamp values to decide
+whether to process more buffers. For possitive @diff, all buffers with
+timestamp &amp;lt;= @timestamp + @diff will certainly arrive late in the sink
+as well. 
+
+The application can use general event probes to intercept the QoS
+event and implement custom application specific QoS handling.

+The @start and @stop values are expressed in @format.
+
+A @rate of 1.0 means normal playback rate, 2.0 means double speed.
+Negatives values means backwards playback. A value of 0.0 for the
+rate is not allowed and should be accomplished instead by PAUSING the
+pipeline.
+
+A pipeline has a default playback segment configured with a start
+position of 0, a stop position of -1 and a rate of 1.0. The currently
+configured playback segment can be queried with #GST_QUERY_SEGMENT. 
+
+ start_type and @stop_type specify how to adjust the currently configured 
+start and stop fields in @segment. Adjustments can be made relative or
+absolute to the last configured values. A type of #GST_SEEK_TYPE_NONE means
+that the position should not be updated.
+
+When the rate is positive and @start has been updated, playback will start
+from the newly configured start position. 
+
+For negative rates, playback will start from the newly configured stop
+position (if any). If the stop position if updated, it must be different from
+-1 for negative rates.
+
+It is not possible to seek relative to the current playback position, to do
+this, PAUSE the pipeline, query the current playback position with
+#GST_QUERY_POSITION and update the playback segment current position with a
+#GST_SEEK_TYPE_SET to the desired position.

+Adds a &quot;data probe&quot; to a pad. This function will be called whenever data

+have the same callback signature as the #GstPad::have-data signal.
+Note that the data will have a reference count greater than 1, so it will
+be immutable -- you must not change it.
+
+For source pads, the probe will be called after the blocking function, if any
+(see gst_pad_set_blocked_async()), but before looking up the peer to chain
+to. For sink pads, the probe function will be called before configuring the
+sink with new caps, if any, and before calling the pad&apos;s chain function.
+
+Your data probe should return TRUE to let the data continue to flow, or FALSE
+to drop it. Dropping data is rarely useful, but occasionally comes in handy
+with events.
+
+Although probes are implemented internally by connecting @handler to the
+have-data signal on the pad, if you want to remove a probe it is insufficient
+to only call g_signal_handler_disconnect on the returned handler id. To
+remove a probe, use the appropriate function, such as

+like EOS, while some can travel out-of-band, like #GST_EVENT_FLUSH_START. If
+the event needs to be serialized with data flow, this function will take the

+#GST_EVENT_IS_UPSTREAM, #GST_EVENT_IS_DOWNSTREAM, and
+#GST_EVENT_IS_SERIALIZED. Note that in practice that an application or
