海康威视网络录像机（NVR）和网络摄像机（IPC）的封装类
1 实时视频预览
实时获取码流数据，如果传入了显示句柄，则视频会显示在窗口句柄上。
2 按时间查询历史视频
选择一个IPC和时间段，返回历史视频列表。
3 历史视频按照文件名回放
根据查询到的历史视频，进行历史回放。
4 历史视频按照时间回放
根据选择的时间段，进行历史视频的回放。
5 历史视频播放控制：快放、慢放、正常播放、暂停、恢复、拖动进度
历史视频在播放过程中，可以进行控制
6 实时预览抓图
实时预览过程中可以抓拍图片
7 历史回放抓图
历史回放过程中可以抓拍图片
8 云台控制
实时预览过程中可以进行云台控制
9 云台预置点设置
预置点设置、运行和删除
10 实时预览远程喊话
如果IPC支持语音对讲，则可以进行远程喊话
假设：
1、NVR的IP为192.168.1.64 用户名为 admin 密码为 admin1234
2、若要查询历史视频，摄像机需要接入NVR的通道，并正常录像
