1 概述
使用libonvif发现onvif摄像头、云台控制。
2 主要功能点
此演示工程展示以下功能：
1）第三方库的使用；
2）查找支持onvif协议的摄像头；
3）控制云台运动、缩放。
3 源码下载与导入
1）下载地址：git clone https://gitee.com/clawclaw/sttonvif.git
注：先设置一下换行符转换 git config --global core.autocrlf false
2）下载后解压，再导入到ApusIDE工作空间打开，具体操作请参考“项目导入”。
3）同步一下项目头文件
4 第三方库配置
4.1源码中已经包含了第三方库libonvif及libxml2
(如要复制到自己的项目中，用ctrl+c和ctrl+v)
4.2模拟器编译配置
a)头文件路径
b)库名及路径
注意，最后的路径"D:\apusv2\runtime-apustest.product\STTonvif\Debug"中的"D:\apusv2\runtime-apustest.product"要改成你导入的项目路径。
4.3 屏的编译设置
a)头文件
${workspace_loc:/${ProjName}/src}
b)库名及路径
"D:\apusv2\runtime-apustest.product\STTonvif\Release"中的"D:\apusv2\runtime-apustest.product"要改成你导入的项目路径

6 操作说明
1. 点击【搜索摄像头】
如局域网内有支持onvif协议的摄像头，会在下拉框中列出。如所买的摄像头支持onvif协议，默认一般是没有启用的，需要进入摄像头去打开这个功能。
2. 下拉框中选择一个摄像头
3. 输入onvif摄像头的用户名和密码（play按钮左侧，注意，不是摄像头的登录用户！）
