SRS

SRS is a self‑hostable media server that handles real‑time video delivery through a range of protocols, including RTMP, WebRTC, HLS, HTTP‑FLV, SRT, MPEG‑DASH, and GB28181. It runs on Linux and macOS and supports multiple CPU architectures such as x86_64, ARMv7, AARCH64, M1, RISCV, LOONGARCH, and MIPS. The server can ingest and output streams encoded with H.264, H.265, AV1, VP9, AAC, Opus, and G.711, providing a flexible backbone for live streaming and low‑latency applications.

The software is built on coroutine technology to avoid asynchronous callback complexity, and it offers cloud‑native deployment options like Docker images and Kubernetes manifests, along with telemetry support. Its design emphasizes high efficiency and straightforward configuration, making it suitable for developers who need a reliable streaming gateway without subscription or tiered licensing constraints.

SRS is released under the MIT license, with some third‑party components under their own licenses, and is considered stable for production use. Documentation includes quick‑start guides for Docker, FFmpeg, OBS, and HTML5 playback, as well as detailed protocol and feature references.
