java海康威视摄像头录制视频

java海康摄像头录制视频

这里就只介绍下录制视频的代码，安装环境啥的就不说了！！！
如果不喜欢，勿喷啊，我也是个刚入行的小白，偶尔记录下开发的一些功能代码，希望下面这段代码能帮到你。

下面是摄像头的初始化和登录的代码，如果你的代码里有，就不要抄我的啦啊！！！

/**
初始化摄像头
**/
public NativeLong initDataVideo() {
        String strPathCom = "/home/czc/java/lib";
        HCNetSDK.NET_DVR_LOCAL_SDK_PATH struComPath = new HCNetSDK.NET_DVR_LOCAL_SDK_PATH();
        System.arraycopy(strPathCom.getBytes(), 0, struComPath.sPath, 0, strPathCom.length());
        struComPath.write();
        boolean loginFlag = hCNetSDK.NET_DVR_Init();
        System.out.print("initSDK is " + loginFlag + "\n");
        System.out.print("error code :" + hCNetSDK.NET_DVR_GetLastError() + "\n");
        hCNetSDK.NET_DVR_SetSDKInitCfg(2, struComPath.getPointer());
        
        hCNetSDK.NET_DVR_SetLogToFile(true, null, false);
        lRealHandle = new NativeLong(-1);
        this.m_strClientInfo = new HCNetSDK.NET_DVR_CLIENTINFO();
        this.m_strClientInfo.lChannel = new NativeLong(1);
        this.m_strClientInfo.lLinkMode = new NativeLong(0);
        this.m_strClientInfo.hPlayWnd = null;
        return lRealHandle;
    }

    //摄像头登录
    public NativeLong myLogin(String ip) {
        HCNetSDK.NET_DVR_USER_LOGIN_INFO struLoginInfo = new HCNetSDK.NET_DVR_USER_LOGIN_INFO();
        HCNetSDK.NET_DVR_DEVICEINFO_V40 struDeviceInfoV40 = new HCNetSDK.NET_DVR_DEVICEINFO_V40();
        struLoginInfo.bUseAsynLogin = 0;

        struLoginInfo.wPort = 8000;//端口
        String address = ip;//你的IP地址
        String userName = "";//用户名
        String passWord = "";//密码
        for (int i = 0; i < address.length(); i++) {
            struLoginInfo.sDeviceAddress[i] = (byte) address.charAt(i);
        }
        for (int i = 0; i < userName.length(); i++) {
            struLoginInfo.sUserName[i] = (byte) userName.charAt(i);
        }
        for (int i = 0; i < passWord.length(); i++) {
            struLoginInfo.sPassword[i] = (byte) passWord.charAt(i);
        }
        struLoginInfo.write();

        userId = hCNetSDK.NET_DVR_Login_V40(struLoginInfo.getPointer(), struDeviceInfoV40.getPointer());
        System.out.println("********** ip :" + ip+ "*****************");
        System.out.println("********** NET_DVR_GetLastError :" + hCNetSDK.NET_DVR_GetLastError() + "*****************");
        System.out.println("********** this.m_strClientInfo.lChannel :"+ this.m_strClientInfo.lChannel + "*****************");
        System.out.println("the userId is :" + userId + "\n");
        return userId;

    }

接下里才是你点进来的真正原因吧，重点来了…

NativeLong NET_DVR_RealPlay_V30(NativeLong lUserID, NET_DVR_CLIENTINFO lpClientInfo,
			FRealDataCallBack_V30 fRealDataCallBack_V30, Pointer pUser, boolean bBlocked);

boolean NET_DVR_SaveRealData(NativeLong lRealHandle, String sFileName);

boolean NET_DVR_StopSaveRealData(NativeLong lRealHandle);

boolean NET_DVR_StopRealPlay(NativeLong lRealHandle);

boolean NET_DVR_Logout_V30(NativeLong lUserID);

boolean NET_DVR_Cleanup();

//开始录像
    public Result startRecord(String ip, String path,String filePath) {
        Result result = new Result();
        //用当前时间戳来命名视频名字
        long time = System.currentTimeMillis();
        if(StrUtil.isBlank(filePath)){
        	filePath=path + time;
        }
        File file = new File(filePath);
    	if (!file.exists()) {
    		file.mkdirs();
    	}
    	String fileName = filePath + File.separator + time + ".mp4";

        initDataVideo();//初始化摄像头
        NativeLong lUserID = myLogin(ip);//登录摄像头
        
        lRealHandle = hCNetSDK.NET_DVR_RealPlay_V30(lUserID, this.m_strClientInfo, null, null, true);
        //如果失败了，在重新来一次
        if (lRealHandle.longValue() == -1) {
            initDataVideo();
            myLogin(ip);
            lRealHandle = hCNetSDK.NET_DVR_RealPlay_V30(this.userId, this.m_strClientInfo, null, null, true);
            System.err.println("---------" + hCNetSDK.NET_DVR_GetLastError());
        }
        //打印错误代码
        System.err.println("---------" + hCNetSDK.NET_DVR_GetLastError());
		//录像
        boolean mark = hCNetSDK.NET_DVR_SaveRealData(lRealHandle, fileName);
        if (!mark) {
            result.setMsg("录像失败");
            result.setSuccess(false);
            System.err.println("----录像失败:" + hCNetSDK.NET_DVR_GetLastError()+"-----");
        }
        //返回结果
        result.setCode(filePath);
        result.setData(lRealHandle);
        return result;
    }

//停止录像
//lRealHandle就是 lRealHandle = hCNetSDK.NET_DVR_RealPlay_V30 他的返回值，在上面有
    public void stopRecord(NativeLong lRealHandle) {
        hCNetSDK.NET_DVR_StopSaveRealData(lRealHandle);
        destroySDK();
        System.err.println(hCNetSDK.NET_DVR_GetLastError());
        System.out.print("*************stoptime************:" + System.currentTimeMillis() + "\n");
    }

    public void destroySDK() {
        boolean stopRealPlay = hCNetSDK.NET_DVR_StopRealPlay(this.lRealHandle);
        boolean logoutV30 = hCNetSDK.NET_DVR_Logout_V30(this.userId);
        boolean cleanup = hCNetSDK.NET_DVR_Cleanup();
        System.out.println("stopRealPlay = " + stopRealPlay);
        System.out.println("logoutV30 = " + logoutV30);
        System.out.println("cleanup = " + cleanup);
    }

到这，海康威视录制视频的功能就可以说做完了。
如果你想录制出来的视频上加上日期时间，看下图：
用网页登录的你摄像头IP，看到如下页面，你就可以设置这些操作了
