大华相机DH-IPC-HFW3237M支持的ONVIF协议

使用libONVIF C++库。

先发现相机。

配置

lib目录
包含
编译提示缺的文件，到libonvif里面拷贝过来。

改UDP端口

代码

使用msvc 2022的向导生成空项目，从项目的main示例拷贝过来。

CameraOnvif::~CameraOnvif()
{
}

调用类。

cpp 复制代码

#include "camera_onvif.h"

camera_onvif::camera_onvif(QWidget *parent)
    : QMainWindow(parent)
{
    ui.setupUi(this);

    auto camera = new CameraOnvif(this);
}

camera_onvif::~camera_onvif()
{}

结果

Found match: Type: "http://www.onvif.org/ver10/network/wsdl":NetworkVideoTransmitter tds:Device Endpoint: http://192.168.1.109/onvif/device_service
