Hm it would be interested to see RIST used in OBS

Yeah! The bitrate shouldn't exceed 8k though and remember the more bitrate you use the more bandwidth the server will use which can mean incurring costs with some providers.

Oof! I'll stick to development I guess grammar isn't my strong suit haha!

Yes and this makes 100% sense. This is my first Open Source project so its definitely something to think about!

Yes I am aware however there is a new service called Glimesh that is utilizing FTL so I dont think it is going to disappear tomorrow. Also I have implemented the server side so it does not matter that it is closed.

Would I like a strong open source community? Absolutely, could you fork this and make money off of it right now? No not even close. Maybe in the future I would consider a different license but at the end of the day if you take this and make it profitable good for you :) my goal wasn’t to make money

This wouldn’t actually solve anything since WebRTC can handle packet loss. The loss is going to be coming from OBS -> Server which unfortunately there isn’t much I can do about that since it uses UDP

I’d love to write an installer that would install and run everything for you

This is planned and will hopefully be coming soon :)

No worries :) enjoy and please let me know what you find!

I’ll get on that first thing tomorrow!

Wow that is a use case that I haven’t considered haha! That sounds awesome! This was made with the intent to be used as a traditional live stream server similar to Twitch or YouTube but honestly it can be used for whatever your heart desires :)

Also, you’re not “hacking” obs. oBS is compiled with the FTL sdk you just have to tell it to use it.

Also the work required to adapt what I have to SRT is non trivial and I would rather have something that works right now and then build in SRT support in the future

So FTL is supported by OBS and was used by Mixer. I’m interested to move to SRT in the future since you’re correct, FTL support will be going away eventually

I can’t wait for you to try it out haha!

As of right now there isn’t a demo. I need to determine the most cost effective way to stream 24/7 then I will put one up

Yup! You could develop a web of WebRTC relays

YouTube and twitch use RTMP which operates over TCP. This means that each time we send a packet we need to ensure that it’s been received which adds latency overhead. Lightspeed uses the FTL protocol which operates over udp thus reducing the latency overhead

Okay now this is awesome! Great work!

Welcome to Project Lightspeed. This is a project that allows anyone to easily deploy their own sub-second latency live-streaming server. In its current state you can stream from OBS [1] and watch that stream back from any desktop browser.

This has been a super fun project which has taught me more than any other project I have done. It uses Rust, Go and React and can be deployed fairly easily on a very lightweight server. For example, I have been doing my test streams on a $5 Digital Ocean droplet and the CPU usage is at around 20%. Granted not a lot of people are watching however it is more lightweight than a solution such as Janus.

The point of this project is twofold. First I wanted to learn more about WebRTC and real-time communication in general. Second, I wanted to provide a platform where people can setup their own little live-stream environment. Maybe you just want a place where you and some friends can hang out or you are sick of the main-stream platforms.

Anyhow as of writing this post it is v0.1.0 and considered an MVP release. In the coming months I (and hopefully some of you :)) will be adding more features and trying to flesh this out into as much of a full featured platform as possible. Feel free to take a look at the repo and let me know what you all think :)
