启动SRS：
# For macOS
docker run --rm -p 1935:1935 -p 1985:1985 -p 8080:8080 \
--env CANDIDATE=$(ifconfig en0 inet| grep 'inet '|awk '{print $2}') -p 8000:8000/udp \
registry.cn-hangzhou.aliyuncs.com/ossrs/srs:v4.0.76
# Or CentOS
docker run --rm -p 1935:1935 -p 1985:1985 -p 8080:8080 \
--env CANDIDATE=$(ifconfig eth0|grep 'inet '|awk '{print $2}') -p 8000:8000/udp \
registry.cn-hangzhou.aliyuncs.com/ossrs/srs:v4.0.76
FFmpeg推流：
docker run --rm --network=host registry.cn-hangzhou.aliyuncs.com/ossrs/srs:encoder \
ffmpeg -re -i ./doc/source.200kbps.768x320.flv -c copy \
-f flv -y rtmp://localhost/live/livestream
也可以使用H5推WebRTC流：webrtc://localhost/live/livestream
播放：
- VLC(RTMP): 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
嗯，你得有个Docker。
