- * @GST_MESSAGE_DURATION: The duration of a pipeline changed. The application
- * can get the new duration with a duration query.
+ * @GST_MESSAGE_DURATION_CHANGED: The duration of a pipeline changed. The
+ * application can get the new duration with a duration query.
* @GST_MESSAGE_ASYNC_START: Posted by elements when they start an ASYNC
* #GstStateChange. This message is not forwarded to the application but is used
- * internally. Since: 0.10.13.

* @GST_MESSAGE_ASYNC_DONE: Posted by elements when they complete an ASYNC
* #GstStateChange. The application will only receive this message from the toplevel
- * pipeline. Since: 0.10.13

* @GST_MESSAGE_LATENCY: Posted by elements when their latency changes. The
- * application should recalculate and distribute a new latency. Since: 0.10.12
+ * application should recalculate and distribute a new latency.
* @GST_MESSAGE_REQUEST_STATE: Posted by elements when they want the pipeline to
* change state. This message is a suggestion to the application which can
- * decide to perform the state change on (part of) the pipeline. Since: 0.10.23.
- * @GST_MESSAGE_STEP_START: A stepping operation was started. Since: 0.10.24
+ * decide to perform the state change on (part of) the pipeline.

* @GST_MESSAGE_QOS: A buffer was dropped or an element changed its processing
- * strategy for Quality of Service reasons. Since: 0.10.29
- * @GST_MESSAGE_PROGRESS: A progress message. Since: 0.10.33
+ * strategy for Quality of Service reasons.
+ * @GST_MESSAGE_PROGRESS: A progress message.
* @GST_MESSAGE_TOC: A new table of contents (TOC) was found or previously found TOC
- * was updated. Since: 0.10.37
+ * was updated.
+ * @GST_MESSAGE_RESET_TIME: Message to request resetting the pipeline's
+ * running time from the pipeline. This is an internal message which
+ * applications will likely never receive.
+ * @GST_MESSAGE_STREAM_START: Message indicating start of a new stream. Useful
+ * e.g. when using playbin in gapless playback mode, to get notified when
+ * the next title actually starts playing (which will be some time after
+ * the URI for the next title has been set).
+ * @GST_MESSAGE_NEED_CONTEXT: Message indicating that an element wants a specific context (Since 1.2)
+ * @GST_MESSAGE_HAVE_CONTEXT: Message indicating that an element created a context (Since 1.2)
* @GST_MESSAGE_ANY: mask for all of the above messages.
