[Live-devel] My server seems to be broken

[Jim Ham]

The server and VLC don't handshake any more. Here is the server start 
message:

<start>
jeh at GreatWall:/srv/media$ sudo ./live555MediaServer &
[1] 79017
jeh at GreatWall:/srv/media$ LIVE555 Media Server
	version 1.13 (LIVE555 Streaming Media library version 2025.04.24).
Play streams from this server using the URL
	rtsp://192.168.1.230/<filename>
where <filename> is a file present in the current directory.
...
</start>

and below is the capture of the handshake via wireshark. Maybe someone 
can spot what's wrong. I've tried this with VLC on a Win11 machine and 
VLC on a Debian 12 machine - same.
