[AG-TECH] h.264 vic

[gurcharan khanna]

hi,

i guess i've been under a misunderstanding all these years!
i thought producer only sent and consumer only received, to
keep things lean and mean. if every vic receives,
then there's a lot of redundant bits coming in with unicast, isn't there?

i wanted the option to turn off receive if i was bandwidth limited, so
the "noMulticast" option is great. i wanted all the videos to show up
if i had plenty of bandwith. (the ISP in Kosovo is supposed to increase
the bandwidth tomorrow...). (if you tune in now you will see that there
are almost no lights on in Kosovo at night!)

so....if i am using the 264ConsumerService, i don't to run a "261"
ConsumerService, right? that would be redundant.

thanks
