54 * @eos_shutdown: if shutdown should first send EOS to the pipeline
55 * @protocols: allowed transport protocols
56 * @auth: the authentication manager
57 * @buffer_size: the kernel udp buffer size
58 * @multicast_group: the multicast group to send to
59 * @medias_lock: mutex protecting the medias.

83 * @gen_key: convert @url to a key for caching shared #GstRTSPMedia objects.
84 * The default implementation of this function will use the complete URL
85 * including the query parameters to return a key.
86 * @create_element: Construct and return a #GstElement that is a #GstBin containing
87 * the elements to use for streaming the media. The bin should contain
88 * payloaders pay%d for each stream. The default implementation of this
89 * function returns the bin created from the launch parameter.
90 * @construct: the vmethod that will be called when the factory has to create the
91 * #GstRTSPMedia for @url. The default implementation of this
92 * function calls create_element to retrieve an element and then looks for
93 * pay%d to create the streams.
94 * @configure: configure the media created with @construct. The default
95 * implementation will configure the 'shared' property of the media.
96 * @create_pipeline: create a new pipeline or re-use an existing one and
97 * add the #GstRTSPMedia's element created by @construct to the pipeline.
98 * @media_constructed: signal emited when a media was cunstructed
99 * @media_configure: signal emited when a media should be configured
101 * The #GstRTSPMediaFactory class structure.
