GB28181国标模拟器，实现对国标摄像头的模拟，可以用于测试GB28181平台对接，模拟国标监控摄像头，实现了注册Register、注销、发送目录、INVITE，BYE，OPTION等信令

GB28181国标平台测试软件，该模拟国标监控摄像头，实现了注册、注销、目录发送、报警模拟、INVITE，BYE、KEEPLIVE、OPTION信令。软件使用电脑摄像头模拟视频通道，实现了发送实时视频功能。注意：如果要模拟实时视频发送，需要安装ffmpeg，需要下载最新版本的ffmpeg放到windows目录下，ffmpeg可以到ffmpeg官网下载。使用该软件需要联网，将本模拟软件放置到可以连接到国标平台的网络里即可。

首先看一下我们的效果图。 这个颜色可能搭配的有些不合适，但基本功能大都实现了。就是你和你同桌对话，你发的消息在你的左侧，而在他设备的右侧。 首先先写好整体的框架，在一个大容器中放两个盒子，分别是左侧和右侧的界面。然后每个盒子里面包含了三大部分：头部、内容区、和底部。只要写好一侧，另一侧进行粘贴复制就可以了。 首先定义一个大的 来盛放左右两个盒子。
