Re: [GnomeMeeting-devel-list] Failed to load avcodec_set_print_fn

[Rajil Saraswat <rajil saraswat imperial ac uk>]

Hi Damien,
   Thanks for your response. I have managed to get it working without 
libavcodec. Also i have posted this information on bugs.gentoo.org for the 
developers to fix it.
I am using NAT with the iptables script on gnomemeeting website to forward 
ports on my internal computer and it is working very well. However, i am 
unable to get netmeeting calls, i guess this is due to the udp ports which 
netmeeting uses.
Will openphone work well with gnomemeeting behind a NAT proxy? Do i need to 
enable special ports in openphone?
Thanks
Rajil
