65 * @create_element: Construct and return a #GstElement that is a #GstBin containing

67 * payloaders pay%d for each stream. The default implementation of this

73 * @configure: configure the media created with @construct. The default
74 * implementation will configure the 'shared' property of the media.
75 * @create_pipeline: create a new pipeline or re-use an existing one and
