How to organize a video broadcast from the user's webcam to the page?

Question

PHP

It is necessary to make everything as convenient as possible for the user, so that he clicks on the button - gets the url, can share this URL with friends and they can also watch the broadcast through the player.
Broadcasting should be carried out from a webcam, and multi-threaded, i.e. so that many people can create their broadcasts. The site is written in PHP, server: Debian + Nginx web server.
I was looking at the rtmp-module for nginx, but something didn’t work out with it ... plus, as I understand it, it’s not dynamic, every time you need to dump configs, open new ports and didn’t really understand how to organize the broadcast through a web page from the user's camera, not from the camera connected to the server.
Please do not offer third-party services like twitch, youtube either, I would like to implement all this using only the resources of my server.

But your task is very difficult. First of all, the complexity is in the server: https://habrahabr.ru/post/111249/ In fact, this is a server for conferences and webinars. These are huge resources and a very complex structure.
