OK, by this I presume that you mean that you’re running *live555ProxyServer* (not ‘LIVE555’) with the “-t” flag, and that the “404 File not found” is occurring on the ‘back-end’ stream.<br>
<br>
Yes, the “LIVE555 Proxy Server” keeps the RTSP connection open. (This is regardless of whether or not it was run with the “-t” flag.) This is because it keeps trying to access the ‘back-end’ stream, in the hope that it will become available in the future. You can see this quite clearly if you add the “-V” flag to live555ProxyServer.<br>
<br>
There is no bug here.<br>
