How to organize a live broadcast in the browser?

Question

Video broadcast

Hello, I am interested in the topic of live broadcasts (hereinafter referred to as PT). The essence of the question: what is needed to organize AT from (for example, OBS) to the browser using JS or PHP at minimal cost and avoiding third-party services. I heard about video js (player), but I still didn’t understand what to do on the server side. I would be very grateful for links to materials and articles on this topic.
