* gst_rtsp_connection_create_from_fd:

* @ip: the IP address of the other end

* @initial_buffer: data already read from @fd
* @conn: storage for a #GstRTSPConnection

* Create a new #GstRTSPConnection for handling communication on the existing

* @fd which should be used before starting to read new data.
*
* Returns: #GST_RTSP_OK when @conn contains a valid connection.
