[Live-devel] Proxy Server Debugging

[Craig Matsuura]

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.

Thanks,
Craig

What is the best way to determine that a proxy server is streaming from
an RTSP source?

The best way is to run, on the computer on which you would run the proxy server
openRTSP -n rtsp://<back-end-stream>
(The "-n" option tells "openRTSP" to display a report (with a beep) when the first RTP packet arrives.)

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 :-)

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.
openRTSP -t -n rtsp://<back-end-stream>
If that works, then adding the "-t" option to the "live555ProxyServer" command line will also work.
