MediaMTX

MediaMTX is a self‑hosted media server and proxy that handles real‑time video and audio streams without requiring external dependencies. It accepts live streams published with protocols such as SRT, WebRTC, RTSP, RTMP, HLS, MPEG‑TS, and RTP, and can serve those streams to clients using the same range of protocols. The software automatically converts between protocols, supports multiple concurrent streams, and can reload its configuration without interrupting active connections.

Typical users include developers and operators who need a lightweight router for live media workflows, such as broadcasting from FFmpeg, GStreamer, OBS, or cameras, and delivering to players, recording tools, or downstream servers. MediaMTX also offers recording to fMP4 or MPEG‑TS, playback of recorded files, authentication via internal, HTTP, or JWT methods, and forwarding or proxying to other servers.

Distinctive aspects are its single‑executable design that runs on Linux, Windows, and macOS, hot‑reloading of configuration, Prometheus‑compatible metrics, a control API, and hook execution on client events. The project is released under the MIT license, is stable, and is free to use without subscription.
