SRS(Simple Realtime Server)

SRS/5.0，Bee 是一个简单高效的实时视频服务器，支持RTMP/WebRTC/HLS/HTTP-FLV/SRT。

SRS/5.0 is a simple, high efficiency and realtime video server, supports RTMP/WebRTC/HLS/HTTP-FLV/SRT.

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.

Note: If image load fail, please see it at here.

Usage

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 is enabled.

Highly recommend that directly run SRS by docker(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.
