海康威视RTSP
1、参考：https://blog.csdn.net/Night_MFC/article/details/104193965

2、视频流与复合流参考：https://zhidao.baidu.com/question/60450633.html
3、主码流与子码流：https://blog.csdn.net/yxwmzouzou/article/details/52367635
4、通过以下配置可以看到视频编码是H.264
5、网络端口
6、通道配置
7、使用这种格式，报错
rtsp://[username]:[password]@[ip]:[port]/[codec]/[channel]/[subtype]/av_stream
codec是上面的H264
rtsp://admin:111111@192.168.1.2:554/h264/ch1/main/av_stream
8、改为新格式，成功
rtsp://username:password@
:101，表示1号通道（摄像头1）的（1）主码流
rtsp://admin:111111@192.168.1.2:554/Streaming/Channels/101
9、注意：一个通道就是一个摄像头。IP不是摄像头的IP，而是硬盘录像机的IP, 用户名和密码也同理，否则访问不了，毕竟直接访问摄像头，一没有缓冲，二也不能作转发。
10、在网页上插入视频
参考：https://www.cnblogs.com/zyxiaohuihui/p/10303771.html
https://blog.csdn.net/yanmuchen/article/details/98207002
11、注意配置strUrl时，不能把用户名和密码加去，即不能用：rtsp://admin:111111@192.168.1.2:554/Streaming/Channels/101
而是分开，否则启动h5ss.bat服务后，会报401的错误。

12、最后的效果
13、安装后可能报错：因为计算机中丢失 VCRUNTIME140.dll。安装vcredist_x64.2017 VCRUNTIME120.dll。安装vcredist_x64.2013
14、插入mp4文件，注意strUrl中是"D:/7.mp4"，不能是"D:\7.mp4"，另外测试时mp4不要选太大，下个一两百M的。
"strToken": "token1",
"nTypeComment": "source type H5_FILE/H5_STREAM/H5_ONVIF",
"nType": "H5_FILE",
"strUrlComment": "url(RTSP/RTMP...) or file path",
"strUrl": "D:/7.mp4",
15、获取历史视频，参考：https://bbs.csdn.net/topics/391846900
