/**
* GST_EVENT_MAKE_TYPE:
* @num: the event number to create
- * @idx: the index in the sticky array
* @flags: the event flags
*
* when making custom event types, use this macro with the num and
* from the pipeline and unblock all streaming threads.
* @GST_EVENT_FLUSH_STOP: Stop a flush operation. This event resets the
* running-time of the pipeline.
+ * @GST_EVENT_STREAM_START: Event to mark the start of a new stream. Sent before any
+ * other serialized event and only sent at the start of a new stream,
+ * not after flushing seeks.
* @GST_EVENT_CAPS: #GstCaps event. Notify the pad of a new media type.
+ * @GST_EVENT_STREAM_CONFIG: contains configuration information for the stream,
+ * for example stream-headers and codec-data.
* @GST_EVENT_SEGMENT: A new media segment follows in the dataflow. The
* segment events contains information for clipping buffers and
* converting buffer timestamps to running-time and
* Since: 0.10.26
* @GST_EVENT_EOS: End-Of-Stream. No more data is to be expected to follow
* without a SEGMENT event.
+ * @GST_EVENT_SEGMENT_DONE: (unimplemented) Marks the end of a segment playback.
+ * @GST_EVENT_GAP: (unimplemented) Marks a gap in the datastream.
+ * @GST_EVENT_TOC: An event which indicates that a new table of contents (TOC)
+ * was found or updated. Since: 0.10.37
* @GST_EVENT_QOS: A quality message. Used to indicate to upstream elements
* that the downstream elements should adjust their processing
* rate.
* execute the step operation. Since: 0.10.24
* @GST_EVENT_RECONFIGURE: A request for upstream renegotiating caps and reconfiguring.
* Since: 0.11.0
+ * @GST_EVENT_TOC_SELECT: A request for a new playback position based on TOC
+ * entry's UID. Since 0.10.37
* @GST_EVENT_CUSTOM_UPSTREAM: Upstream custom event
* @GST_EVENT_CUSTOM_DOWNSTREAM: Downstream custom event that travels in the
* data flow.
