海康威视RTSP摄像头转RTMP推流前端方案（浏览器兼容及权限验证）

  videojs的播放flv格式RTMP流需要浏览器运行flash插件，但是chrome现在已经不支持flash了，所以我们使用flvjs前端插件作为替代方案，并在流媒体服务器上加入了权限验证功能限制用户访问。

  此方案是基于上一节中的方案进行的优化，所以没有提及的地方和原方案保持不变。
一. 在nginx中安装nginx-http-flv-module插件
  有编译好的版本直接使用就行，然后修改nginx.conf文件。

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

        location = /50x.html {
            root   E:/nginx/html;
        }
    }
}

路径配置

  路径配置按个人需求来就行，nginx的权限验证可以看官方文档
二. 使用flvjs插件播放流
