What is MediaMTX used for?

MediaMTX is a zero-dependency live media server and proxy that routes real-time audio and video streams between protocols such as RTSP, RTMP, SRT and WebRTC. It is a good fit for bridging camera streams into WebRTC or HLS, recording live streams to disk and routing OBS Studio output to several protocols.

Is MediaMTX open source?

Yes. MediaMTX is open source under the MIT licence. Its source code is on GitHub at bluenviron/mediamtx and is written mainly in Go.

Yes. MediaMTX is open source, so the software itself is free to use.

Can I self-host MediaMTX?

Yes. MediaMTX can be self-hosted on your own server or infrastructure; there is no official hosted version.

What is MediaMTX an alternative to?

MediaMTX is an open-source alternative to Wowza. Other open-source alternatives to Wowza include SRS, Ant Media Server and OvenMediaEngine.

Is MediaMTX actively maintained?

Yes. The most recent commit to MediaMTX was on 2 October 2026, and the latest release is v1.21.1, published on 20 September 2026. The project has 20k stars on GitHub.

About MediaMTX

MediaMTX is a live media server and media proxy that publishes, reads, proxies, records and plays back real-time video and audio streams. It acts as a media router, taking a stream from one end and delivering it to the other, with an emphasis on efficiency and portability.

Streams can be published over Media-over-QUIC, SRT, WebRTC, RTSP, RTMP, HLS, MPEG-TS or RTP using tools like FFmpeg, GStreamer or OBS Studio, and they are converted automatically between protocols so viewers can read them in a different format. Several streams can run at once on separate paths, and recordings can be written to disk in fMP4 or MPEG-TS and played back later.

Operational features include hot configuration reloading, internal, HTTP or JWT authentication, a control API, Prometheus-compatible metrics, and hooks that run external commands when clients connect or publish. The Go program ships as a single executable for Linux, Windows and macOS and is released under the MIT license, so it can be self-hosted anywhere a binary runs.
