I don't think there is comprehensive information about that. We all do pretty much the same, implement the Selective Forwarding Unit (SFU) model. The idea is the SFU will receive a number of streams for each user (usually up to 3, in low, mid and high resolutions) and then it will forward one of them to each other participant depending on things like available bandwidth, requested video size, etc. There are a number of Open Source implementations available, in case you want to study it deeper: - Jitsi videobridge: https://github.com/jitsi/jitsi-videobridge - Janus: https://github.com/meetecho/janus-gateway - mediasoup: https://github.com/versatica/mediasoup - (p)ion: https://github.com/pion/ion-sfu - meddoze: https://github.com/medooze/media-server-node And probably more!

Yes, there are many self-hosted options out there. https://github.com/meetecho/janus-gateway works well for multi-party video with up to about 15 users in a room assuming everyone has a reasonably reliable connection.

What you will want is a SFU.

We use Janus Gateway, and it works really well: https://github.com/meetecho/janus-gateway We have upwards of 100 simultaneous users on it every day, and at the moment it seems to be 100% reliable.

Like I said, Janus doesn't do anything by default except for some core RTC stuff and push packets around. You have to implement your own use-case via a plugin. It sounds like the Video Room plugin that's implemented in C is not exactly what you want. You can write your own plugin (maybe based on it) yourself. If you want to implement E2E via insertable streams then you can start right here: https://github.com/meetecho/janus-gateway/blob/master/plugin...

No: the vast majority of the VideoRoom functionality is written in C, and it is where all of the actually-hard-to-do video SFU stuff -- like quality control feedback and SVC support, particularly in an end to end encryption context with all the codec-specific workarounds--is commingled together with the notion of "rooms" (which is a really awkward and specific high-level abstraction with a schema that you have to abuse for basic use cases). https://github.com/meetecho/janus-gateway/blob/master/plugin... Yes: if you don't want any of the complex video functionality, you can easily write your own Janus plugin, and that maybe sounds reasonable for some trivial game "SFU" where you are just going to move around some data channel packets... but at that point you can (and I argue should) just use libwebrtc (I do this, and I helped one of my fri

Janus itself doesn't make any assumptions about a specific use-case. All the functionality outside of the core RTC stuff is implemented with plugins. The default "Video Room" implementation is just a Lua script [0]. Mozilla has written their own SFU plugin (in Rust) [1] for game networking that powers Mozilla Hubs [2].

We changed the URL from https://github.com/meetecho/janus-gateway to the project homepage, which is generally preferred when a project is being discussed for the first time on HN. Especially if it also links to its GitHub page or other repository. I found previous submissions, but no comments except https://news.ycombinator.com/item?id=22610510.

Janus [1] is a much more capable webrtc gateway that's pluggable to do anything you want. Jitsi is like a Wowza type server. Stay away. [1] https://github.com/meetecho/janus-gateway

You might want to try Janus Gateway instead. It works fine on firefox, and is stable and reliable. https://github.com/meetecho/janus-gateway

I'm teaching myself C (pure hobby) and I really liked these codebases: https://github.com/antirez/kilo https://github.com/meetecho/janus-gateway The obvious caveat here is that I have no idea what makes a good C codebase. What I liked in both was I was able to: compile and run them easily make tiny changes and observe them easily read and understand a reasonable portion of them enjoy the odd comment here and there
