Hi Ross, Thanks for your reply. I don't have a NAT between my server and client, and if I am going to set up IP multicast routing between my server and client networks, what device will I need ? Or what technology do I need to take?

In the local area network, I worked fine.But In the public network, the client couldn't receive the video data. Then I asked somebody and was told that the multicast data can't be transmitted through NAT. So, is there a way that can make the multicast data spread over the public network using live555 ? No, you cannot stream via multicast beyond a single LAN, unless IP multicast routing has been set up between your server and client network(s) - which is rarely the case. Instead, you should stream via unicast, using the “testOnDemandRTSPServer” demo application as a model; see http://live555.com/liveMedia/faq.html#liveInput-unicast However, if you have a NAT (rather than just a router) between your server and client, then it’s unlikely that you will be able to use RTSP/RTP streaming between them, especially if your server is not on the public Internet. (Probably your only hope - in this case - would be to use a “LIVE555 Proxy Server” outside your NAT.)
