SRS/4.0，Leo，是一个简单高效的实时视频服务器，支持RTMP/WebRTC/HLS/HTTP-FLV/SRT。
SRS is a simple, high efficiency and realtime video server, supports RTMP/WebRTC/HLS/HTTP-FLV/SRT.
SRS is licenced under MIT, but some depended libraries are distributed using their own licenses.
Build SRS from source or docker(CN / EN), please read Wiki: Gettting Started(CN / EN):
git clone -b 4.0release 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/livestreamNote: It's also able to publish by H5 if WebRTC is enabled.
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
- H5(WebRTC): webrtc://localhost/live/livestream
From here, please read wikis:
- Getting Started, please read Wiki first.
- 中文文档：起步，不读Wiki一定扑街，不读文档请不要提Issue，不读文档请不要提问题，任何文档中明确说过的疑问都不会解答。
