* @GST_EVENT_SEGMENT: A new media segment follows in the dataflow. The

* @GST_EVENT_EOS: End-Of-Stream. No more data is to be expected to follow

+ * @GST_EVENT_TOC: An event which indicates that a new table of contents (TOC)

* @GST_EVENT_QOS: A quality message. Used to indicate to upstream elements
