[AG-TECH] Having trouble with receiving video

[Pelotte, Emile J.]

Chris,

I connected to the APAG lobby which did have two other sites present. I
was able to view the chat discussion between the two individuals but was
unable to get their video to show up on my screen. I also tried to
connect using Unicode with a couple different bridges from the menu as
well and did not have any success. I spoke with one of our network
administrators and had them set up a one to one NAT for the pc that I am
using for the client and had him open all ports until I am able to get
the video issue resolved. Once resolved, I will have him close the ports
that are not required based on the document that Michael Miller provided
the link for in an earlier response. Should a box pop up attempting to
connect even if there is an issue with multicast/unicast? My screen
shows the three cameras only and does not even have a grey or black box
for the other sites that I am attempting to display. Just to ensure that
I have the services added properly, which services would be required in
order to display/capture video and receive/transmit/capture audio? I
have a separate pc that is used to capture video/audio and I am using
the display pc to run the client. 

Thanks,

Emile

Emile,

If you didn't see any other sites connected to the venue you were in  
but you did see other data in there and there were no particular error  
messages, then its quite likely that everything is working correctly.  
If there were no other participants in a venue then you wouldn't  
expect to see any video streams other than your own. You could try the  
APAG Lobby where one or two sites are often just sitting there and  
generating video that you should be able to see. The APAG Lobby is at:
     https://vv3.ap-accessgrid.org:8000/Venues/default

Another potential issue (which may be the cause of the no video  
problem in your tests with U Arkansas) is that your network may not be  
multicast enabled. You can bypass this by selecting a multicast- 
unicast bridge from the Tools->Bridges menu.
