Hu Fererico, thanks for the tips. Yes, they are in the same machine (Ubuntu 11.04) Anyway I did telnet 192.168.1.4 8554 it says: "Trying 192.168.1.4... telnet: Unable to connect to remote host: Connection refused" Thanks I hope I could resolve this as soon as is possible.

If not, check the firewall; anyway, try to connect to the server using telnet: telnet <rtsp server ip address> 8554 and then type: DESCRIBE rtsp://<rtsp server ip address>/test RTSP/1.0 CSeq: 1 You should see something like RTSP/1.0 200 OK CSeq: 1 Content-Type: application/sdp [more lines] _______________________________________________ gstreamer-devel mailing list <a href="mailto:gstreamer-devel@lists.freedesktop.org" target="_blank">gstreamer-devel@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" target="_blank">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> </blockquote></div>
