最近感觉使用国标协议的开发者有很多，我们国标GB28181流媒体服务器提供流转发服务，负责将GB28181设备/平台推送的PS流转成ES流，然后提供RTSP、RTMP、FLV、HLS多种格式进行分发，实现web浏览器、手机浏览器、微信等各种终端无插件播放。
之前有开发者说我们国标GB28181的流媒体服务器需要查看视频的时候，只能单独查看一路视频，想同时查看多路视频的时候，就不是很方便操作。
原本的界面如下：
我们的研发人员也对这个多分屏的问题进行了研究，在前几天实现了国标GB28181流媒体服务器的多分屏操作（我由衷觉得我的研发部同事们都很厉害啊！），界面如下图：
以下是实现代码，大家可以参考一下：
