> 100 outgoing video feeds. Not many machines can encode 100 video feeds in realtime

The server will send 9 video streams to each connection, but it has to process only 10 video streams since it will send the same video data to all clients, if we ignore client bandwidth.

The parent post explicitly took the client bandwidth into account, that's why it was 100 instead of 10.

But your point about 10 vs 9 still stands. Still, 81, and if you bucket into 3 tiers, that's still 27. Which at least scales linearly instead of quadratically.

Exactly. It scales linearly, not quadratically. I forgot to mention that since clients do the "original" encoding, the server actually does less work (regarding resolution tiers).

agreed. do not agree with OP that all 100 require transcoding
