Hi Andrew,


Thanks for the reply.

I actually did some further testing from my end and found that it's
something that is definitely beyond my control. I stopped the firewall and
still no video streaming worked.

Now I have liaised with the central IT department, they would like to know
specifically what ports are required, multicast/unicast settings and
anything that may help the Network administrator.


Any ideas where to get hold of such information?

This definitely sounds like a firewall issue.  The audio tool (RAT) may be
able to "poke a hole" in your firewall, but the video tool (vic) will not be
able to do this.  This would explain why you can hear but not see.

Hi there,


I am running a PIG access grid and the issues I am currently experiencing it
that I am not seeing any video streaming.

I have tested this with another University and it seems that they can see
and hear me.

The capture source tab of the Video Source menu has been checked and the
right option is selected there.

I am only about to use Unicast as the network is configured that way. In
addition I am able to hear the other parties.


The latest versions of python and AG have been installed.

Any help would be greatly appreciated. Thank you.

Kind regards,

Johnny Ly
