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

Note: It's also able to publish by H5 if WebRTC is enabled.
