HappyOnvif - ONVIF协议摄像机接入平台

平台功能：在平台上录入相机后台设置的onvif信息，对外提供webapi接口，如获取播放地址，ptz控制，预置点控制等功能

开发环境：NetCore 6.0 + Sqlite

 

一、相机管理

1. 添加相机

2. 控制面板
2.1 获取播放地址，并播放rtsp流
2.2 PTZ控制
2.3 预置点管理（获取，前往，添加，删除）

2.4 语音对讲（语音广播，开始对讲，结束对讲）需要支持onvif backchannel

 rtsp转webrtc程序，用于html页面播放rtsp地址流

二、日志信息

三、 Swagger

 四、程序结构

 五、部分接口代码
