In the spirit of POSSE, accessibility, and a general love of tinkering, when I started doing streaming I wanted to set things up to stream to peertube, youtube, twitch, and as many other places as I wanted. I had to setup three tools to do this, OBS, a plugin called obs-multi-rtmp, and a (optional but very, very useful and highly reccomended) server running nginx-rtmp 

So the steps in a nutshell are:

1. Install/Build OBS: https://obsproject.com/wiki/install-instructions#linux
2. Add the multi-rtmp-plugin: https://github.com/sorayuki/obs-multi-rtmp
3. Optional: Setup Nginx to take some pressure off your streaming computer: https://github.com/arut/nginx-rtmp-module

Settings these tools up in a way that streamed to those three services was more of a project then I thought it would be (I setup ngnxrtmp first but a bug prevented it from multicasting to peertube, which is the place I wanted to stream to the most)

So for posterity here is a quick rundown of the process I used to stream to multiple places. Feel free to edit this if you find spelling errors or just generally hate 

I am going to assume you are using a fresh uptaded and empty linux machine running either debian 10 or debian 11, since thats what these notes assume and I am just copy pasting right now till I clean up the notes.
