How to set up your own private RTMP server using nginx

This worked well for me, but the document can be updated in one respect: It is not necessary to compile Nginx, because libnginx-mod-rtmp can be installed from the repositories (at least with Ubuntu). So nginx and the mod can be installed with apt.
Also another problem might occur: One of our favorite live platforms ;) Facebook does only accept RTMPS connections which Nginx does not support. This problem can be solved using Stunnel, here is a good documentation: https://sites.google.com/view/facebook-rtmp-to-rtmps/home

I set this up on my Odroid HC2. Because I have OMV running and access it with port 80, I had to change the default listen port from port 80 to something else. I can still use my Odroid's internet IP address in the rtmp link in OBS to successfully stream. So, like, rtmp://192.168.1.54/live. I have a dynamic dns setup to access the Odroid HC2 server, but when I go use rtmp://dynamicdns.address.com/live in OBS, it does not work. What do I need to do (port forwarding, whatever) to stream remotely?

Great guide but for some reason I'm running into the same issue as another. When I stream my CPU usage goes just as high as when I'm streaming normally to twitch.

I couldn't get this to work because I was using a network bridge, but my friend who wasn't got his to work fine. I guess just keep that inmind if you're doing this.
