Android 集成海康威视监控 SDK，实现监控录像的查看

Android 集成海康威视监控 SDK，实现监控录像的查看

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：

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：

添加权限

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

 

@Override
public boolean onTouch(final View v, final MotionEvent event) {
    if (!NotNull.isNotNull(h1)) return false;
    Log.d(TAG, "onTouch: ");
    new Thread() {
        @Override
        public void run() {
            switch (v.getId()) {
                case R.id.btn_Up:
                    if (event.getAction() == MotionEvent.ACTION_DOWN) {
                        h1.startMove(8, m_iLogID);
                    }
                    if (event.getAction() == MotionEvent.ACTION_UP) {
                        h1.stopMove(8, m_iLogID);
                    }
                    break;
