SRS/5.0(Bee) is a simple, high efficiency and realtime video server, supports RTMP, WebRTC, HLS, HTTP-FLV, SRT, MPEG-DASH and GB28181.
Note: The single node architecture for SRS, for detail please see here.
SRS is licenced under MIT by default, and SRS is also licensed under MIT or MulanPSL-2.0. Please note that MulanPSL-2.0 is compatible with Apache-2.0, and some third-party libraries are distributed under their licenses.
Please refer to the Getting Started or 中文文档：起步 guide.
To build SRS from source:
git clone -b 5.0release 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/livestreamPlay 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: In addition to FFmpeg or OBS, it is possible to publish by H5 via WHIP as well. To enable WebRTC to publish and convert it to RTMP, please refer to the wiki(CN, EN) documentation. It is essential to ensure the candidate(CN or EN) is set correctly for WebRTC to avoid potential issues, as it can cause significant problems.
Note: It is highly recommended to run SRS directly with docker(CN / EN), CVM(CN / EN), or K8s(CN / EN). However, compiling SRS from source code is also possible and easy. For detailed instructions, please refer to the "Getting Started"(CN / EN) guide.
Note: If you require HTTPS for WebRTC and modern browsers, please refer to the HTTPS API(CN / EN), HTTPS Callback(CN / EN), and HTTPS Live Streaming(CN / EN) documentation. Additionally, SRS works perfectly with an HTTPS proxy like Nginx.
