批量修改海康摄像头gb28181配置

由于本人所在公司是物联网业务巨多，平时跟海康摄像头打交道比较多。

同时，公司使用GB28181协议播放视频流。

当摄像头多了，一个一个配置就比较麻烦了。同时海康的SDK(HCNetSDK)缺少GB28181配置。

只好根据海康(设备网络SDK使用手册.chm)C的代码来定义了

1. 在HCNetSDK中新建一个类

 public static class  NET_DVR_GBT28181_ACCESS_CFG extends Structure {
        public int dwSize;
        public byte byEnable;
        public byte byTransProtocol;
        public short wLocalSipPort;
        public byte[] szServerID = new byte[64];
        public byte[] szServerDomain = new byte[128];
        public byte[] szSipServerAddress = new byte[128];
        public short wServerSipPort;
        public byte byProtocolVersion;
        public byte byRes3;
        public byte[] szSipUserName = new byte[64];
        public byte[] szSipAuthenticateID = new byte[64];
        public byte[] szSipAuthenticatePasswd = new byte[32];
        public int dwRegisterValid;
        public byte byHeartbeatInterval;
        public byte byMaxHeartbeatTimeOut;
        public byte byStreamType;
        public byte byDeviceStatus;
        public int dwRegisterInterval;
        public int dwAutoAllocChannelID;
        public byte[] szDeviceDomain = new byte[128];
        public byte[] byRes4 = new byte[116];
    }

2. 然后再设置GB28181配置（先要运行成功海康的Demo,不然不知道怎么使用）

 public void setGb28181Config() {
        HCNetSDK.NET_DVR_GBT28181_ACCESS_CFG config = new HCNetSDK.NET_DVR_GBT28181_ACCESS_CFG();
        config.write();
        Pointer pointer = config.getPointer();
        IntByReference lpBytesReturned = new IntByReference(0);
        //先读取配置，让sdk填充一些属性
        boolean b1 = hCNetSDK.NET_DVR_GetDVRConfig(lUserID.intValue(), 3249, new NativeLong(0xFFFFFFFF).intValue(),
                pointer, config.size(), lpBytesReturned);
        config.read();
        if (b1) {
            config.dwSize = config.size();
            config.byEnable = 0x01;
             //SIP服务器ID
            config.szServerID = "44010200492000000001".getBytes();
            //SIP服务器域
            config.szServerDomain = "4401020049".getBytes();
            // SIP服务器地址
            config.szSipServerAddress = "192.168.18.11".getBytes();
            //SIP服务器端口
            config.wServerSipPort = 5060;
     
            config.byProtocolVersion = 0x02;
            // SIP用户名
            config.szSipUserName = "34020000001180000001".getBytes();
             // SIP用户认证ID
            config.szSipAuthenticateID = "34020000001180000001".getBytes();
            //密码
            config.szSipAuthenticatePasswd = "admin123".getBytes();
            config.byHeartbeatInterval = 0x0a;
            config.write();
            boolean b = hCNetSDK.NET_DVR_SetDVRConfig(lUserID.intValue(), 3250, new NativeLong(0xFFFFFFFF).intValue(), config.getPointer(), config.size());
            if (b) {
                System.out.println("设置成功：" + hCNetSDK.NET_DVR_GetLastError());
            } else {
                System.out.println("设置失败："+ hCNetSDK.NET_DVR_GetLastError());
              
            }

        } else {
            System.out.println("获取配置失败：" + hCNetSDK.NET_DVR_GetLastError());
           
        }
    }
