====== NGINX - Videostreaming ======

work in progress

Nginx comes with a RTMP Plugin, which can be configured to play stream HLS, RTMP and DASH.
The Setup is a bit tricky and working values for Bitrate, etc are hard to find.
 

====== Basic Installation ======

.. in Debian Buster is easy

  apt install nginx nginx-rtmp-module

====== Security ======

.. is not so easy.

1. Level is to allow only some IPs to publish streams via deny / allow settings in nginx
2. Level is to add a Stream Key. This does not work for me yet in OBStudio
3. ..
