75 * @get_element: Construct and return a #GstElement that is a #GstBin containing
76 * the elements to use for streaming the media. The bin should contain
77 * payloaders pay%d for each stream. The default implementation of this

80 * #GstRTSPMedia for @url. The default implementation of this
81 * function calls get_element to retrieve an element and then looks for
82 * pay%d to create the streams.
83 * @configure: configure the media created with @construct. The default
84 * implementation will configure the 'shared' property of the media.
85 * @create_pipeline: create a new pipeline or re-use an existing one and
86 * add the #GstRTSPMedia's element created by @construct to the pipeline.
