Hi Jonas,
could you add license information for the android-motion-detection code?

Thanks and cheers,
Raimund

An indexOutofBounds Exception is thrown if the detector is fed with continuous images instead of camera as the input source.
consume(bitmap,bitmap.width,bitmap.height) results in an indexoutofbounds exception at
int y = (0xff & (yuv420sp[yp])) - 16; in decodeYUV420SPtoLuma method
Are the width and height related to camera instead of the bitmap.

Just wanted to log this crash I'm seeing on my 10" Fire Tablet (running Lineage OS)

I tried to make this switch camera, but for some reasons it won't switch the camera

Hello,

I am using this library for motion detection. It is work fine. But I am facing issue related to distance of motion detection. Also I have tried for different Leniency values .This library not cover enough long distance for motion detection.
Is there any why to detect motion for long distance. Could you please tell me motion detection depends of which feature of camera.

I want to get the position of the area where the motion detected, and I found your paintDifferences(int[] data) in Comparer.java.

Could you explain more about that?

I would like to know the following function for what purpose:

Private long lastCheck = 0;

Is located in MotionDetector.java

What is the value of it?

Thanks.

on calling : camera.takePicture(null, null, pictureCallback);
the app is crashing

Hi, need some help... i need to capture video recording on every motion detected, this is my relevant code:

void motionDetectorCallback(){
        motionDetector.setMotionDetectorCallback(new MotionDetectorCallback() {
            @RequiresApi(api = Build.VERSION_CODES.KITKAT)
            @Override    public void onMotionDetected() {
                try {
                    initRoutine();
                }catch(NullPointerException ignored){}   Log.w(TAG,"Motion detected");
            }
            @Override
            public void onTooDark() {    Log.w(TAG,"Too dark here"    ); }  })  ;}


    @RequiresApi(api = Build.VERSION_CODES.KITKAT)
    void initRoutine() {
        if (!firstRun) {
            enoughTimeHasPassed = false;
            long now = System.currentTimeMillis();
            if ( (now -lastRecordingTime) > 500 )
                enoughTimeHasPassed = true;
        }
        if (smbConnection.isConnected() & !recording & serviceRunning & enoughTimeHasPassed)
{            textRecordingStatus.setText("RECORDING");
            textRecordingStatus.setTextColor(Color.GREEN);
            firstRun = false;
            Log.w(TAG,"RECORD STARTED");
            record();  }}


    @RequiresApi(api = Build.VERSION_CODES.KITKAT)
    private void record() {
        if (!recording) {
            recording = true;
            prepareVideoRecorder();
            recorder.start();
            Handler handler = new Handler();
            handler.postDelayed(new Runnable() {
                @Override
                public void run() { stopRecorder(); }  }, time*1000);  }   }

What is happening is that if i run the app normally the first cycle the app uses the callback correctly and record is launched, after x time the recording autostops trough stopRecorder() function. Here the motion detector callback is not running anymore, while if i'm testing the app in debug mode everything works perfectly.
I have the same problem if i start the app in debug mode and then disconnect the phone
What is the problem? O.o

edit: testing the problem i implemented a callback to log the callback, and i can see that the service is running, the only problem is that nextData is always null on MotionDetector after the first run, maybe is MediaRecorder overwriting access to the camera? why is it working in debug mode then? I even tried disabling proguard
