What it is
A single program, written in Go, that reads and publishes live streams over RTSP, RTMP, WebRTC, SRT, HLS and several other protocols, and can proxy, record and play them back. It has no dependencies and no interpreter to install.What it is good for. Anyone with a camera and somewhere to put the picture. Security cameras, a workshop feed, a low-latency preview for a live show, a stream you do not want to hand to a platform. If you have ever tried to get a camera's RTSP feed to appear in a browser, this is the piece that was missing.
- MIT, one executable file, no dependencies, and it runs on Linux, Windows and macOS.
- It reads one protocol and serves several, which removes a whole class of conversion work.
- It can record to disk and play back, so it is a recorder as well as a server.
- It serves the stream and does nothing else. There is no page, no chat, no accounts.
- Live video is expensive to move. Ten viewers at a decent quality will be the largest line on your hosting bill.
- It opens a lot of ports, and putting it on the open internet without thinking about that is a mistake.
- ossrs/srs
A larger media server of the same kind, older and with more knobs, and correspondingly more to read before it works.
