<font face="Courier New, Courier">Ross, thank you for your quick
reply.<br>
<br>
I'm trying to create a H.264 video stream that looks like it comes from
an IP camera using rtsp-and-rtp-tunneled-over-http. I'm not trying to
view it in a browser. Since you explained that the stream does not really
use http, then it is not feasible to use a web server to proxy it, which
I wanted to do to for networking reasons to change its IP address. So
I'll set that objective aside.<br>
<br>
Referring to my initial 6 questions:<br>
<br>
<b>1) live555ProxyServer adds a new subsession, causing VLC to stop
displaying streams. <br>
<br>
</b>Here's the console log you requested. I see a line, received RTCP
bye, which precedes creation of the new subsession. Note that as I view
the stream from live555ProxyServer, I also view the stream that is input
to live555ProxyServer. The input stream plays without interruption, so
it's not clear where the 'bye' comes from that seems to be creating the
problem:<br>

<b>This repeats indefinitely.<br>
<br>
4. Cannot view stream with http URL. <br>
<br>
</b>Fixed as you described by using a RTSP URL.<br>
<br>
<b>5. Cannot view http stream from Internet. <br>
<br>
</b>I consider this a near-ultimate test since the router blocks access to other streams. I forwarded private port 80 from the machine with live555ProxyServer to public port 8100, for both tcp and udp, for the LAN IP address used by the machine with live555ProxyServer. I know my ISP is not blocking http traffic because I have a web server on my LAN that is accessible from the Internet via public port 8000. I set up access to the tunneled stream in VLC and can view the tunneled stream directly from the machine with live555ProxyServer. I used the configuration in question 1 above (so it's without -T xxxx). On my LAN, I used the following URL in VLC to try to view the stream via the Internet, without success: <a href="rtsp:///" eudora="autourl">rtsp://</a><my public IP address>:8100/proxyStream. A similar procedure for viewing a web server on my LAN via the Internet, works. How do I fix this ?<br>
<br>
<b>6. Regarding a pipe, I'll worry about this later.<br>
<br>
7. (new) Is it necessary to place a trailing "/" after each rtsp source in the command line ?<br>
