<div>Hi, gstreamer-devel:</div> <div> </div> <div>    This is because rtspsrc uses multiple transport methods in `Transport' header while sending out `SETUP' method. You can modify `gst_rtspsrc_create_transports_string' function in gstrtspsrc.c.</div> <div> </div> <div>    Actually, I'd say that the logic in `gst_rtspsrc_create_transports_string' is subject to RFC 2326(RTSP), so I think this is an implementatin problem of RTSP server. RTSP server which obeys the RFC 2326 can handle this situation, that means the client provides multiple transport methods in `SETUP' method and the server picks one which it prefers.</div> <div> </div> <div>Eric Zhang  </div> <div>2008/8/23, Farkas Levente <<a href="mailto:lfarkas@lfarkas.org">lfarkas@lfarkas.org</a>>: <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">hi, we retest rtsp with the latest gstreamer-plugins-good-0.10.9 and still broken. here are a more detaild description why compared vlc with gstreamer (since vlc is working): 1.
