[AG-TECH] VideoProducerService is also receiving???

[ULM AccessGrid]

UPDATE:

I found a quick way to make the VICs on my video machine transmit(sort of)
only.  I just added a firewall line that blocked all incoming sources that
were not on my subnet.  I now have three VICs with only one video per VIC on
my video box.  Thanks Michael for letting me know it was not just me.  You
helped me think of this solution.  FINALLY AG2.2 is running well on my
multi-os node.

I am in the process of making a comprehensive HOW-TO to install AG2.2 on
Fedora2.  It should be finished within the hour.  It will come with links to
all files needed for the install.

Here's the link:

Let me know what you think.

Adam,

I've seen this question a couple times.  Yes, this is normal behavior in my 
experience.  You should notice though that all the streams in the 
VideoProducer VICs muted.  I believe this eliminates the bandwith usage 
that those streams would need, but there still maybe a small amount in 
order for VIC to know that the stream is still there.  I'll let the vic 
experts chime in here...

It would make more sense if a single instance of VIC could be configured to 
handle multiple inputs/transmits but I'll bet there would be a whole lot of 
changes to the code necessary to handle that.

hope this helps
