How to use nginx as RTMP server?

bash.sh

# create rtmp stream from video
ffmpeg -stream_loop -1 -i test02.mp4 -c:a copy -c:v libx264 -f flv rtmp://www.example.com/mytv/test02
ffmpeg -stream_loop -1 -i test02.mp4 -f flv rtmp://www.example.com/mytv/test02

http-server.conf

location /hls {
    # Serve HLS fragments
    types {
        application/vnd.apple.mpegurl m3u8;
        video/mp2t ts;
    }
    root /tmp;
    add_header Cache-Control no-cache;
}

nginx.conf

load_module modules/ngx_rtmp_module.so;

rtmp {
    access_log  /var/log/nginx/rtmp_access.log;
    server {

        listen 1935;

        chunk_size 4000;

        # TV mode: one publisher, many subscribers
        application mytv {

            # enable live streaming
            live on;
            hls on;
            hls_path /tmp/hls;

            # publish only from localhost
            allow publish all;

            allow play all;
            # publish directly by nginx
            exec_static ffmpeg -stream_loop -1 -i /var/www/test_hls_rtmp.mp4 -c:a copy -c:v libx264 -f flv rtmp://localhost:1935/mytv/test02;
        }
    }
}
