docker-nginx-rtmp VS nginx-rtmp-module

I prefer this Docker image https://github.com/alfg/docker-nginx-rtmp/

Regarding the first solution, I've looked through some of the source code for the NGINX RTMP Module, and I believe the code I would need to modify lives in the ngx_rtmp_cmd_module.c file: https://github.com/arut/nginx-rtmp-module/blob/master/ngx_rtmp_cmd_module.c

You could look at setting up the RTMP module on nginx and securing it with lets encrypt - https://github.com/arut/nginx-rtmp-module

foobar2000 -> OBS -> nginx server running nginx-rtmp-module

If stuck for a server I've used this in the past. nginx with an RTMP module.

Also linking a config file I commented. Unsure if it'll still work and you can definitely simplify it for OP's needs. It was a proof of concept for a streaming service I was thinking up before realising how much money I don't have, haha

If you can only output something like RTMP, then your options are a bit more limited. Set up an RTMP server somewhere (e.g. https://github.com/arut/nginx-rtmp-module), and connect with another client that will soak up the RTMP into a file - I think ffmpeg should be able to do that, but I've had the most luck with GStreamer. Again, avoid transcoding it on the way into a file, both ffmpeg and GStreamer can be set up to never touch the encoded media (just copy/pass it along).

Are you using the rtmp nginx module?

But, if it's something you want to do, and want to do it inexpensively you want to use Nginx-RTMP - http://nginx-rtmp.blogspot.com/ - this is a free version of AntMedia Server without the $70 per month fee.
