10/31/2022, 3:23 PMis livecloud designed for multicast streaming then, for optimised latency among very small groups with multi-way communication, would regular WebRTC with a signalling server be better? If the participants are in different countries the mesh server may really help though?

10/31/2022, 3:24 PMI guess I can just try it 🙂

10/31/2022, 3:27 PMYeah, the mesh is to help with stability and reliability when users are connecting from different locations, because direct connections might have higher latency or packet loss. If you only have a few users all in the same location, then only one server would be used

10/31/2022, 3:32 PM@swift-lamp-15520 to add, we’ve tried to build a system that is flexible and scales well to all these different use cases. Cloud works as well for the “multicast” use case, as it does for small meetings. They all operate off the same sub-100ms latency benchmark.

10/31/2022, 3:33 PMok perfect - sounds like the best way forward.

10/31/2022, 3:33 PMkind of related... for the realtime aspect udp is ok to keep the latency low as possible. But I'd like to be able to record the audio session with tcp style packet loss recovery, for a high quality, high bit rate recording. Do you think this is possible in principle? It would need two audio streams I think, tee'd off the mic input. This would need a server in the middle too.

10/31/2022, 3:34 PMIt’s designed to function as a general-purpose, ultra-low-latency, highly scalable WebRTC network.

10/31/2022, 3:35 PMIt sounds like what you want in parallel is a high-quality, perfect audio recording?

10/31/2022, 3:38 PMHave to think about that one. We don’t support a force-tcp option at the moment.

10/31/2022, 3:39 PMok cool. thanks for your help so far. I'm going to try some things out.

10/31/2022, 5:56 PMDo you somehow horizontal scale rooms? Cause I can't understand how you manage 100k video consuming connections without scaling of a room itself.
a
able-gigabyte-21598
10/31/2022, 6:40 PMYes, rooms scale horizontally with cloud

10/31/2022, 6:59 PM@swift-lamp-15520 for audio we can already handle quite a bit of loss in egress with opus/RED. it can handle up to 40% packet loss
