55 * @eos_shutdown: if shutdown should first send EOS to the pipeline
56 * @protocols: allowed transport protocols

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