Building a live stream server to re-stream a RTMP stream from OBS to Facebook / YouTube / twitch at the same time for free. The build is done with a raspberry pi 3 which you can hardwire into your local network to restream. Software is NGNIX with the RTMP add-on and stunnel to re-stream to Facebook over a secure connection. I'm not very good in Linux so if I can do it.... there are some basic thing you might want to know but most can be copy paste from this tutorial or from the websites I use during the tutorial.
