On a side note, I gave Vivotek engineers the mailing list info and I
hoped they would join. We are working directly with them and I will
see them tomorrow.<br>

Thanks,<br>

The best way is to run, on the computer on which you would run the
proxy server
<div><span class="Apple-tab-span" style="white-space:pre"> </span>openRTSP
-n <a class="moz-txt-link-freetext" href="rtsp://">rtsp://</a><back-end-stream></div>
<div>(The "-n" option tells "openRTSP" to display a report (with a
beep) when the first RTP packet arrives.)</div>
<div><br>
</div>
<div>If "openRTSP" successfully receives data from the back-end
server, then the "LIVE555 Proxy Server" - when run on the same
stream - will also receive data (because both "openRTSP" and the
"LIVE555 ProxyServer" use the same RTSP client code). (Unless,
of course, the back-end server is a buggy 'Vivotek' camera, but
you now know to stop using those :-)</div>
<div><br>
</div>
<div>If, however, "openRTSP" fails to receive data from the
back-end server, then the problem may be that the back-end
server is behind a firewall that is blocking RTP/UDP packets.
So instead, try requesting RTP/RTCP-over-TCP streaming, by
adding the "-t" option to "openRTSP" - i.e.</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>openRTSP
-t -n <a class="moz-txt-link-freetext" href="rtsp://">rtsp://</a><back-end-stream></div>
<div>If that works, then adding the "-t" option to the
"live555ProxyServer" command line will also work.</div>
