## Description

This project is a real-time communication and media streaming server designed for broadcasting, recording, and distributing audio and video content. It functions as a live streaming server and an RTMP media server, providing the infrastructure necessary to deliver real-time media to multiple concurrent viewers over a network.

The system distinguishes itself through a multi-protocol media gateway that supports RTMP, E-RTMP v2 for modern codecs like HEVC and AV1, and HTTP media tunneling to bypass restrictive firewalls. It further acts as a real-time communication platform by synchronizing shared state objects across connected clients and pushing asynchronous updates via server-sent events.

The server covers broad capability areas including media session management, live stream recording, and video-on-demand delivery. It incorporates security features such as TLS/SSL encryption and protocol traffic validation, while using hierarchical user scoping to control data visibility across global, web, and room levels.

Administrative utilities allow the server to be deployed as a daemon on Linux and Windows for background execution.
