+ * @short_description: A factory for media pipelines
+ * @see_also: #GstRTSPMediaFactory, #GstRTSPMedia
+ *
+ * The #GstRTSPMediaFactoryMTPR is responsible for creating or recycling
+ * #GstRTSPMedia objects based on the passed URL.
+ *
+ * The default implementation of the object can create #GstRTSPMedia objects
+ * containing a pipeline created from a launch description set with
+ * gst_rtsp_media_factory_set_launch().
+ *
+ * Media from a factory can be shared by setting the shared flag with
+ * gst_rtsp_media_factory_set_shared(). When a factory is shared,
+ * gst_rtsp_media_factory_construct() will return the same #GstRTSPMedia when
+ * the url matches.
