Nginx-rtmp

docker方式

有很多个镜像可供选择，我搞个下面的这种。

• https://hub.docker.com/r/alfg/nginx-rtmp

docker run -it -p 1935:1935 -p 8080:80 --rm alfg/nginx-rtmp

http://localhost:8080/stat

rtmp://localhost:1935/stream/$STREAM_NAME

http://localhost:8080/live/laker1/index.m3u8

整体配置如下

    worker_connections 1024;
}

rtmp {
    server {
        listen 1935;
