We need to set up nginx with the nginx-mod-rtmp module
yay -S nginx nginx-mod-rtmp
Be aware that of March 2025 the nginx-mod-rtmp package doesnt update that frequently and therefor needs an old nginx version.
Then install/configure the rtmp server and the http server, which will host the frontend site with make js backer-install
Install Dependencies:
pacman -S chromium xorg-server-xvfb obs-server
Then just run the backerend script.
backerend <RTMP Output Stream>
