简单的直播搭建流程

本微博在借鉴其他大牛之后，觉得应该写一个直播的完整流程，虽然简单，但是会有一个宏观感受：

搭建nginx服务器
工具：
nginx下载地址：https://nginx.org/download/nginx-1.13.6.zip
nginx-rtmp-module-master.zip下载地址：https://github.com/arut/nginx-rtmp-module/

使用方法：
将两个工具文件解压，然后将这个nginx-rtmp-module-master放到nginx解压文件的一级目录底下

配置文件conf\nginx-win-rtmp.conf的方法：

## Lua examples !

#           rewrite_by_lua '

#             if ngx.var.http_host ~= "localhost" then

#               return ngx.exec("/robots_disallow.txt");

#             end

#           ';

#         }



    #error_page  404              /404.html;



    # redirect server error pages to the static page /50x.html

    #

    error_page   500 502 503 504  /50x.html;

    location = /50x.html {

        root   html;

    }



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

    #

    #location ~ \.php$ {

    #    proxy_pass   http://127.0.0.1;

    #}



    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

    #

    #location ~ \.php$ {

    #    root           html;

    #    fastcgi_pass   127.0.0.1:9000; # single backend process

    #    fastcgi_pass   myLoadBalancer; # or multiple, see example above

    #    fastcgi_index  index.php;

    #    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;

    #    include        fastcgi_params;

    #}



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

    # concurs with nginx's one

    #

    #location ~ /\.ht {

    #    deny  all;

    #}

}



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

#

#server {

#    listen       8000;

#    listen       somename:8080;

#    server_name  somename  alias  another.alias;



#    location / {

#        root   html;

#        index  index.html index.htm;

#    }

#}



# HTTPS server

#

#server {

#    listen       443 ssl spdy;

#    server_name  localhost;



#    ssl                  on;

#    ssl_certificate      cert.pem;

#    ssl_certificate_key  cert.key;

#    ssl_session_timeout  5m;

#    ssl_prefer_server_ciphers On;

#    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

#    ssl_ciphers ECDH+AESGCM:ECDH+AES256:ECDH+AES128:ECDH+3DES:RSA+AESGCM:RSA+AES:RSA+3DES:!aNULL:!eNULL:!MD5:!DSS:!EXP:!ADH:!LOW:!MEDIUM;



#    location / {

#        root   html;

#        index  index.html index.htm;

#    }

#}

}
如果需要支持HLS流：
则修改如下：
rtmp {
server {
listen 1935;
chunk_size 4000;
application hls { #rtmp推流请求路径
live on;
hls on;
hls_path C:\nginx\hls;
hls_fragment 5s;
}
}
}
说明：hls_path 为m3u8，及ts文件存储路径； hls_fragment为每个ts的时长

启动服务器
进入windows的cmd;
cd nginx-1.7.11.3-Gryphon
nginx.exe -c conf\nginx-win-rtmp.conf

验证是否配置成功
打开浏览器，输入localhost，如果出现

表示连接成功

使用ffmpeg推流
使用的资源为mp4，命名为test.mp4（本人处理时，为了方便，将视频文件放到ffmpeg目录底下）
进入win cmd，cd到ffmpeg目录，如果不是管理员，可使用如下形式：
（cd +/d +路径）的方式进入，然后输入命令：
ffmpeg -re -i localFile.mp4 -c copy -f flv rtmp://localhost/live/streamName
注意：直接推mp4流失败，得先remux成flv（毕竟flv和rtmp都是Adobe公司的，配套使用）

使用ffplay拉流
ffplay rtmp://localhost/live/streamName

结论
这样就可以完成一个简单的直播流程了
