From time to time VLC is unable to open a specific UDP port to play a stream. Windows 7 or XP. VLC errors and logs it can't open the port.

udp://@:5003 is one of the ports for example
using netstat the ports are not in use.
firewall is disabled.
using wireshark we can see the stream coming across the port.

Generally we just change the config to use another port or reboot and it works. Next hour 5003 opens without a problem. Shazam!!

I don't think this is a VLC issue necessarily but it's becoming a pain!!

Any thoughts??

Thanks!

Have you tried netstat command?

Yes

Before running VLC we run netstat to see which ports are in use. Since 5003 isn't in use we try udp://@:5003 but it gives us the error that it can't open the port. When VLC is running and we have tried to open the port netstat still doesn't show the ports in use.
