* 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_QOS: A quality message. Used to indicate to upstream elements
* that the downstream elements should adjust their processing
* rate.
