I really don't understand that why we need an IP multicast here. <br>As I understand :<br> - I have a RTSP (live555) server at
(192.168.27.73) and it listen on all interfaces (0.0.0.0:8554).<br> - I have a RTSP client (VLC) at (192.168.27.235) and request for the media on server : rtsp://192.168.27.73:8554/cow.mpg<br>As above : the server and client must see each other. And in the log, client has contacted with sever, and sent the SETUP & PLAY commands. But the stream hasn't been transported. Client sent TEARDOWN after 10s because it didn't receive any data. <br>Both of them show error : "Unable to determine our source address. This computer has an invalid IP address : 0x0".<br><br>Please help me to find out my error. <br><br>Thank you very much,<br>Cam Hoang.<br><BR><BR><span style="font-weight:bold;color:rgb(0, 0, 255);">Sincerely,</span><br><font style="font-family:bookman old style, new york, times, serif;" size="4"><span style="font-style:italic;font-weight:bold;">Cam Hoang</span></font><br><p>
