一、官网获取海康威视SDK
二、打开IDEA,新建项目导入SDK
在project Structure-> modules添加Jna.jar和examples.jar
在project Structure-> sdks添加Jna.jar和examples.jar
三、修改HCNetSDK.java
修改HCNetSDK.dll加载路径
HCNetSDK INSTANCE = (HCNetSDK) Native.loadLibrary(System.getProperty("user.dir") +"/HCNetSDK.dll", HCNetSDK.class);
修改 PlayCtrl.dll加载路径
PlayCtrl INSTANCE = (PlayCtrl) Native.loadLibrary(System.getProperty("user.dir") +"/PlayCtrl.dll", PlayCtrl.class);
四、运行程序
输入IP,用户名,密码,端口,点击注册
预览成功
回放功能,通道号为i+33
五、SDK程序函数调用顺序
六、SDK实战-手动录像功能
创建定时任务
task
@Scheduled(fixedRate = 60000)//每小时执行一次 @Async public void startVideoTask() { try { HKUtil.startVideo(v.username,v.password,v.ip); }catch (Exception e){ e.printStackTrace(); } }
HKUtil.java
public static void startVideo(String username,String password,String ip) { //匿名内部类实现方式 new Thread() { //重写run方法 @Override public void run() { boolean initSuc = hCNetSDK.NET_DVR_Init(); HKUtil a = new HKUtil(); a.init(username,password,ip); } }.start(); }
/************************************************* 函数: "注册" 按钮单击响应函数 函数描述: 注册登录设备 *************************************************/ public void init(String username,String password,String ip) {//GEN-FIRST:event_jButtonLoginActionPerformed //注册之前先注销已注册的用户,预览情况下不可注销 if (bRealPlay) { System.out.println("注册新用户请先停止当前预览!"); return; } if (lUserID.longValue() > -1) { //先注销 hCNetSDK.NET_DVR_Logout_V30(lUserID); lUserID = new NativeLong(-1); m_iTreeNodeNum = 0; m_DeviceRoot.removeAllChildren(); } //注册 m_sDeviceIP = ip;//设备ip地址 m_strDeviceInfo = new HCNetSDK.NET_DVR_DEVICEINFO_V30(); int iPort = 8000; lUserID = hCNetSDK.NET_DVR_Login_V30(m_sDeviceIP, (short) iPort, username, password, m_strDeviceInfo); long userID = lUserID.longValue(); if (userID == -1) { m_sDeviceIP = "";//登录未成功,IP置为空 System.out.println("注册失败"); } else { try { hCNetSDK.NET_DVR_StartDVRRecord(lUserID, new NativeLong(0xffff), new NativeLong()); Thread.sleep(30000); hCNetSDK.NET_DVR_StopDVRRecord(lUserID, new NativeLong(0xffff)); jButtonExitActionPerformed(); } catch (Exception e) { e.printStackTrace(); } } }
流程大致如下:
注销登录-》构建登录参数-》登录注册-》开始录制-》睡眠-》停止录制
对应方法:
hCNetSDK.NET_DVR_Logout_V30(lUserID);//注销登录 m_strDeviceInfo = new HCNetSDK.NET_DVR_DEVICEINFO_V30();//构建登录参数 hCNetSDK.NET_DVR_Login_V30(m_sDeviceIP,(short) iPort, username, password, m_strDeviceInfo);//登录注册 hCNetSDK.NET_DVR_StartDVRRecord(lUserID, new NativeLong(0xffff), new NativeLong());//开始录制 Thread.sleep(30000);//睡眠 hCNetSDK.NET_DVR_StopDVRRecord(lUserID, new NativeLong(0xffff));//停止录制
结果如图
