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 ser…

Thanks for sharing! I was actually just looking for something like this earlier today, can't wait to try it out.

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

This project is pretty cool, I’ll tinker around with it tomorrow.

As an aside, I’ve noticed you’re building out your own stream protocol stack (FTL/LightSpeed). What’s the reasoning there? Seems slightly inconvenient to have to “hack” OBS to make the output stream work. Will FTL support be merged into OBS in the future?

If you’re just trying to avoid the latency of RTMP then I might suggest considering the existing SRT protocol[1]. It’s been open source for a while and is well-established(native support in OBS core and optional in FFMPEG). Seems to already solve a lot of the transport-level stuff that you’re working on with FTL.

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

Demo link doesn't work.

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

What about a recording of a demo on YouTube?

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

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

Very cool - mind showcasing/telling us some use-cases? I'm thinking... if you pair this with a tool to control input (mouse/keyboard) you could have a ligth-fast (pun intended) VNC server with HD resolution?

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 :)

I’ll get on that first thing tomorrow!
