[AG-TECH] Greyed Vic Windows

Hello Todd,

Can you describe the computer hardware and camera model he is using?  Have
you noticed any difference between connecting into the venue server via a
unicast bridge and connecting over multicast?  Do both endpoint computers
have their firewalls turned off?  

Also there a network bandwidth cap on the local users network?  Better yet,
what sort of network is he going over?  Is it a university, corporate, or
commercial network?

Thank you,

John Langkals

Hey all - looking for help/suggestions...

I've just helped a user set up a new personal node and he is reporting an
odd problem with vic.

We successfully set up a VideoService and restarted video.  From my side
(the remote side), all is
working well.  I can see the person's video fine, so the camera is working
well and vic is properly
sending the camera feed out.

The problem is on his side (the local side).  The video feeds (and
thumbnails) on his side are
greyed out. Before you suggest he's using a videoproducer service instead of
a videoservice - or has
the sources muted, this isn't the case.  It is definitely a video service,
and in fact, we've run
vic from the command line and have had the same experience.  The 'mute'
buttons are NOT activated;
however the symptoms are identical to that.  Toggling the mute buttons does

One of extenuating circumstance that may be affecting this is that the user
is in France - and is
using a French language version of Windows.... not sure if this would affect
things, but thought I'd
throw it out there anyway.

Anyone seen this behavior before?  Its AG2.4 with recommended python,
wxpython etc - and other
videoconferencing technologies (netmeeting) work fine.

Thoughts? Ideas?

Thanks in advance,
