nginx - 如何 : stream with ffmpeg and nginx rtmp, Ubuntu

Question

安装了 https://nginx.org/en/linux_packages.html 的 nginx在 Ubuntu 18.04 中

sudo apt -y install curl gnupg2 ca-certificates lsb-release ;
echo "deb http://nginx.org/packages/ubuntu `lsb_release -cs` nginx" | sudo tee /etc/apt/sources.list.d/nginx.list ;
curl -fsSL https://nginx.org/keys/nginx_signing.key | sudo apt-key add - ;
sudo apt update ;
sudo apt install nginx ;

nginx 启动并运行

$ ps -aux | grep nginx
root      5602  0.0  0.0  33348   880 ?        Ss   17:03   0:00 nginx: master process nginx
nginx     5603  0.0  0.0  33744  2748 ?        S    17:03   0:00 nginx: worker process

与 /etc/nginx/nginx.conf

rtmp {
    server {
        listen 1935;
        chunk_size 4096;

        application live {
            live on;
            record off;
            allow publish 127.0.0.1;
            deny publish all;
        }
    }
}

ffmpeg -f lavfi -i testsrc -t 30 -pix_fmt yuv420p -f flv rtmp://localhost/live/test产量

线索:
1935 端口上似乎没有任何监听。 netstat -tap | grep 1935一无所获
线索2:
尽管 ps显示应用程序正在运行， systemctl status nginx.service显示应用状态关闭

考虑到其他stackoverflow问题，检查的事情:

试图连接到 rtmp://localhost/live/test在 nginx.conf 中，应用程序被正确命名为 live

nginx.conf 正确放置在/etc/nginx/，不存在其他 nginx.conf 文件，并且 nginx -s reload调用以确保已加载

没有 localhost conf文件中的实例，全部重命名为127.0.0.1

安装支持rtmp的nginx sudo apt install nginx-core nginx-common libnginx-mod-rtmp而不是 sudo apt install nginx然后运行 ​​nginxsudo systemctl restart nginx
