Beta0 wroteFunny, I thought the OP was on budget considering he wanted to do it all on a smart tv
I highly recommend using TrueConf in that case. Nvidia 1050 GPU works great for a school I've set up, especially with VP9 with the terrible uploads we have, you can actually see participant faces with it.
Fully fledged conference systems aren't expensive compared to this, about the same with worse quality as they're outdated.
i am on a budget ... i will use the general idea but not with these specs .. an old i5 6th gen with an ssd and 8 GB of ram .. with a good cam/mic and a regular TV
no gpu whatsoever
