nginx ＋ rtmp 推流

环境

安装Homebrow

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

安装nginx

下载nginx项目到本地

brew tap homebrew/nginx

执行安装

brew install nginx-full -with-rtmp-module

到这一步，nginx和rtmp模块已经安装好了。

查看nginx信息：

brew info nginx-full

==> Caveats
Docroot is: /usr/local/var/www

The default port has been set in /usr/local/etc/nginx/nginx.conf to 8080 so that
nginx can run without sudo.

nginx will load all files in /usr/local/etc/nginx/servers/.

- Tips -
Run port 80:
 $ sudo chown root:wheel /usr/local/opt/nginx-full/bin/nginx
 $ sudo chmod u+s /usr/local/opt/nginx-full/bin/nginx
Reload config:
 $ nginx -s reload
Reopen Logfile:
 $ nginx -s reopen
Stop process:
 $ nginx -s stop
Waiting on exit process
 $ nginx -s quit

To have launchd start homebrew/nginx/nginx-full now and restart at login:
  brew services start homebrew/nginx/nginx-full
Or, if you don't want/need a background service you can just run:
  nginx

nginx安装所在位置：

/usr/local/Cellar/nginx-full/1.12.2/bin／nginx

nginx配置文件所在位置：

/usr/local/etc/nginx/nginx.conf

运行nginx

nginx

在浏览器输入：http://localhost:8080

内容如下：

Welcome to nginx!

If you see this page, the nginx web server is successfully installed and working. Further configuration is required.

For online documentation and support please refer to nginx.org.
Commercial support is available at nginx.com.

Thank you for using nginx.

代表nginx安装成功

如果终端提示：

nginx: [emerg] bind() to 0.0.0.0:8080 failed (48: Address already in use)

则表示8080端口被占用了，查看端口的pid

lsof -i tcp:8080

结果如下：
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
xxx 7056 ygdx_lk 7u IPv4 0xf49473a52270b0b 0t0 TCP *:http-alt (LISTEN)

kill掉占用8080端口的pid

kill 7056(占用8080端口的pid)

然后重新执行nginx

nginx常用方法：

命令	含义
nginx -s reload	重新加载配置文件
nginx -s reopen	重新加载日志
nginx -s stop	停止nginx
nginx -s quit	退出nigix

配置rtmp

修改nginx.conf这个配置文件（/usr/local/etc/nginx/nginx.conf）
修改后如下：

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

    worker_connections  1024;
}

rtmp {
    server{
        listen 1066;
        #直播流配置
        application rtmplive{
            live on;
            #为rtmp设置最大链接数。默认为off
            max_connections 1024;
        }
        application hls{
            live on;
            hls on;
            hls_path /usr/local/var/www/hls;
            hls_fragment 1s;
        }
    }
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {

        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80

        #}

        # deny access to .htaccess files, if Apache's document root

        #    deny  all;
        #}
    }


    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {

    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}


    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;

    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    location / {

    #        index  index.html index.htm;
    #    }
    #}
    include servers/*;
}

主要添加了这段配置：

rtmp {
    server{
        listen 1066;
        #直播流配置
        application rtmplive{
            live on;
            #为rtmp设置最大链接数。默认为off
            max_connections 1024;
        }
        application hls{
            live on;
            hls on;
            hls_path /usr/local/var/www/hls;
            hls_fragment 1s;
        }
    }
}

安装ffmpeg工具

brew install ffmpeg

推流

视频文件地址：/Users/xu/Desktop/input.mp4
推流拉流地址：rtmp://localhost:1935/rtmplive/home
acc：RTMP的音频格式
flv： RTMP的视频格式

ffmpeg -re -i /Users/xxx/Desktop/input.mp4 -vcodec libx264 -acodec aac -f flv rtmp://localhost:1066/rtmplive/home

拉流

打开VLC播放器
File->Open Network…
设置拉流地址：rtmp://localhost:1066/rtmplive/home

推流以后，点击open开始播放。

注意点：
打开网络偏好设置->状态->“Wi-Fi”已连接至“XXX”，其 IP 地址为 192.168.2.85

rtmp://192.168.2.85:1066/rtmplive/home则与上面的localhost是等价的。后续用手机进行推流，就不能用localhost推流了，只能改成对应的ip推流。
