I think a lot of WebRTC video conferencing solutions don't do server side video encoding - the clients encode their own stream(s) for high/low bandwidth, and server side they have a selective-packet-forwarder, or SPF. The clients are usually smart enough to only send the high bandwidth stream when that speaker is in focus.
