I am using a Android Studio, OpenCV and JavaCameraView to display frame from camera. I want create a simple Mat frame recorder. For example I want save a 100 last frames and then I want a display it in JavaCameraView.

I have vector recordedCameraFrames for store a Mat frames. In function onCameraFrame I have ...

@Override
public Mat onCameraFrame(CameraBridgeViewBase.CvCameraViewFrame cameraFrame) {

colorMat = cameraFrame.rgba();

if(frameCountForRecording < 100){
    recordedCameraFrames.add(colorMat);
    frameCountForRecording++;
}       
else {
    isRecordedFramesReadyToPlay = true;
    recordedCameraFrames.remove(0);
    recordedCameraFrames.add(colorMat);
}

And then when I activate PLAY_DETECTED_FRAMES_VIEW_MODE I want play recorded frames ...

case PLAY_DETECTED_FRAMES_VIEW_MODE:

if(isRecordedFramesReadyToPlay == true && canPlayRecordedFrames == true) {
        if (indexOfRecordedFrame == 99) {
              indexOfRecordedFrame = 0;
        }
        indexOfRecordedFrame++;
        colorMat = recordedCameraFrames.get(indexOfRecordedFrame).clone();
}
break;

so.. what's the problem ? – Ravi Mar 29 '19 at 14:14
Problem is that, function onCameraFrame still return original colorMat, no colorMat from vector recordedCameraFrames. – KicoSVK Mar 29 '19 at 14:27
Where did you return the `colorMat` from the function? – Bahramdun Adil Mar 29 '19 at 15:35
In the end of function onCameraFrame I return colorMat. – KicoSVK Mar 29 '19 at 15:38
You do the same thing in every call `colorMat = cameraFrame.rgba();` in `onCameraFrame()` function. And also you overtide the colorMat in both functions? – Bahramdun Adil Mar 29 '19 at 15:48
