海康威视 Android studio 集成使用

配置

切换Android studio 到project目录下，分别将jar包与armeabi包复制进去lib文件夹下：

这里写图片描述

设置app bulid.gradle文件主要是添加CPU限制只支持32位以及添加so包的路径、添加jar包依赖：

这里写图片描述

添加权限

    <uses-permission android:name="android.permission.INTERNET" />    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>    <uses-permission android:name="android.permission.CAPTURE_AUDIO_OUTPUT"/>    <uses-permission android:name="android.permission.RECORD_AUDIO"/>

SDK使用

在调用摄像头的Activity的oncreate（）中初始化SDK

    private boolean initeSdk() {        // init net sdk        if (!HCNetSDK.getInstance().NET_DVR_Init()) {            Log.e(TAG, "HCNetSDK init is failed!");            return false;        }        HCNetSDK.getInstance().NET_DVR_SetLogToFile(3, "/mnt/sdcard/sdklog/",true);//log保存的路径        return true;    }

登陆

private int loginNormalDevice() {        // get instance        m_oNetDvrDeviceInfoV30 = new NET_DVR_DEVICEINFO_V30();        if (null == m_oNetDvrDeviceInfoV30) {            Log.e(TAG, "HKNetDvrDeviceInfoV30 new is failed!");            return -1;        }        // call NET_DVR_Login_v30 to login on, port 8000 as default        int iLogID = HCNetSDK.getInstance().NET_DVR_Login_V30(ADDRESS, PORT,                USER, PSD, m_oNetDvrDeviceInfoV30);        if (iLogID < 0) {            Log.e(TAG, "NET_DVR_Login is failed!Err:"                    + HCNetSDK.getInstance().NET_DVR_GetLastError());            return -1;        }        if (m_oNetDvrDeviceInfoV30.byChanNum > 0) {            m_iStartChan = m_oNetDvrDeviceInfoV30.byStartChan;            m_iChanNum = m_oNetDvrDeviceInfoV30.byChanNum;        } else if (m_oNetDvrDeviceInfoV30.byIPChanNum > 0) {            m_iStartChan = m_oNetDvrDeviceInfoV30.byStartDChan;            m_iChanNum = m_oNetDvrDeviceInfoV30.byIPChanNum                    + m_oNetDvrDeviceInfoV30.byHighDChanNum * 256;        }        Log.i(TAG, "NET_DVR_Login is Successful!");        return iLogID;    }

相机预览

//预览        final NET_DVR_PREVIEWINFO ClientInfo = new NET_DVR_PREVIEWINFO();        ClientInfo.lChannel = 0;        ClientInfo.dwStreamType = 0; // substream        ClientInfo.bBlocked = 1;        //设置默认点        thread = new Thread(new Runnable() {            @Override            public void run() {                while (!Thread.currentThread().isInterrupted()) {                    SystemClock.sleep(1000);                    runOnUiThread(new Runnable() {                        @Override                        public void run() {                            if (isShow)                                startSinglePreview();//预览                        }                    });                }            }        });        thread.start();

预览摄像头需要开启线程，监听预览成功后停止线程，不然界面会显示黑色。

startSinglePreview()代码：

private void startSinglePreview() {        if (m_iPlaybackID >= 0) {            Log.i(TAG, "Please stop palyback first");            return;        }        RealPlayCallBack fRealDataCallBack = getRealPlayerCbf();        if (fRealDataCallBack == null) {            Log.e(TAG, "fRealDataCallBack object is failed!");            return;        }        Log.i(TAG, "m_iStartChan:" + m_iStartChan);        NET_DVR_PREVIEWINFO previewInfo = new NET_DVR_PREVIEWINFO();        previewInfo.lChannel = m_iStartChan;        previewInfo.dwStreamType = 0; // substream        previewInfo.bBlocked = 1;        m_iPlayID = HCNetSDK.getInstance().NET_DVR_RealPlay_V40(m_iLogID,                previewInfo, fRealDataCallBack);        if (m_iPlayID < 0) {            Log.e(TAG, "NET_DVR_RealPlay is failed!Err:"                    + HCNetSDK.getInstance().NET_DVR_GetLastError());            return;        }        isShow = false;        if (NotNull.isNotNull(thread)) {            thread.interrupt();        }        h1 = new CameraManager();        h1.setLoginId(m_iLogID);        Intent intent = getIntent();        if (NotNull.isNotNull(intent) && intent.getIntExtra("INDEX", -1) != -1) {            int point = app.preferences.getInt("POINT", 0);            boolean b = HCNetSDK.getInstance().NET_DVR_PTZPreset(m_iPlayID, PTZCommand.GOTO_PRESET,                    point);        }    }

控制台操作
