Not really.  The code uses multicast to (try to) figure out the 
host's IP address.  This error is usually caused by not having IP 
multicast configured properly on your system.

Make sure that you have a route for 224.0.0/4


>Can it not use at least 127.0.0.1 ?

Yes, you could - but if you're a server, you really want an IP 
address that other computers can reach.

The problem may be with "ffplay", not with our server.  However, 
"ffplay" is not our software, so if you have any questions about 
"ffplay", you'll need to ask them on another mailing list.

I suggest that you try using VLC <http://www.videolan.org/vlc/> as a 
client instead.
