SRS(Simple Realtime Server)

SRS/6.0 (Hang) is a simple, high efficiency and realtime video server, supports RTMP/WebRTC/HLS/HTTP-FLV/SRT/MPEG-DASH/GB28181, Linux/Windows/macOS, X86_64/ARMv7/AARCH64/M1/RISCV/LOONGARCH/MIPS, and essential features.

Note: The single node architecture for SRS, for detail please see here.

SRS is licenced under MIT or MulanPSL-2.0, and note that MulanPSL-2.0 is compatible with Apache-2.0, but some third-party libraries are distributed using their own licenses.

Usage

Please read guide Getting Started or 中文文档：起步.

To build SRS from source:

git clone -b develop https://gitee.com/ossrs/srs.git &&
cd srs/trunk && ./configure && make && ./objs/srs -c conf/srs.conf

Open http://localhost:8080/ to check it, then publish by FFmpeg or OBS as:

ffmpeg -re -i ./doc/source.flv -c copy -f flv -y rtmp://localhost/live/livestream

Play the following streams by players:

• RTMP (by VLC): rtmp://localhost/live/livestream
• H5(HTTP-FLV): http://localhost:8080/live/livestream.flv
• H5(HLS): http://localhost:8080/live/livestream.m3u8

Note that if convert RTMP to WebRTC, please use rtmp2rtc.conf:

• H5(WebRTC): webrtc://localhost/live/livestream

Note: Besides of FFmpeg or OBS, it's also able to publish by H5 if WebRTC(CN, EN) is enabled, please remember to set the CANDIDATE(CN or EN) for WebRTC.

Highly recommend that directly run SRS by docker(CN / EN), Cloud Virtual Machine(CN / EN), or K8s(CN / EN), however it's also easy to build SRS from source code, for detail please see Getting Started(CN / EN).

Note: If need HTTPS, by which WebRTC and modern browsers require, please read HTTPS API(CN / EN) and HTTPS Callback(CN / EN) and HTTPS Live Streaming(CN / EN), however HTTPS proxy also works perfect with SRS such as Nginx.
