hello, thanks for your great responce, I have change my route like this : destination : 255.255.0.0 mask : 255.255.255.0 gateway : 192.168.0.254, my workstation IP is 192.168.0.2.
but I have a other probleme, i try to read the file trasnmit with testMPEG1or2VideoStreamer with vlc , in udp with the port 1234. I just want use the RTP protocole, and don't have a serveur RSTP, so I erased the part of code I think is useless for simple RTP streming, but I must be wrong, because VLC cannot read this rtp stream, the error :" main private error : cannot prefill buffer" is in VLC. can you say me if the modified code is correct ??? I am not sure that Groupsock rtcpGroupsock(*env, destinationAddress, rtcpPort, ttl) is usefull... there is the code modified : /********** This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version.

Beginning to read from file... ********************************************************************************** I don't understand, because my IP adresse is correct, but i'm using the same computer to stream and receive, Nonetheless, something is wrong with the networking configuration of your system, because neither of the methods we use to determine the computer's IP address - (1) multicast loopback and (2) gethostname()+gethostbyname() - is working. The most common reason for this error is that IP multicast is not configured correctly on your system. Make sure that you have a route installed for 224/8. -- Ross Finlayson Live Networks, Inc. http://www.live555.com/_______________________________________________ live-devel mailing list live-devel@lists.live555.com http://lists.live555.com/mailman/listinfo/live-devel Pensez a l'environnement : avez-vous besoin d'imprimer ce message Think Environment : Do you need to print message ?
