This is Elixir/Erlang/BEAM's core use case, the thing it was designed to do, coordinating and routing with failover and fallbacks a large number of realtime feeds. The original use case was phone calls, but other than the fact these video streams are much much larger per second, most of the principles carry over.
As much as I am a critic of the system, if this is your use case, this is out-of-the-box a very strong foundation for what you need to get done.
