Return to Question

I am currently using the method setMaxFrameSize of the class CameraBridgeViewBase in a android app for down-regulating the captured frame of my main camera. In my use case, I need a very low resolution, because a good performance is needed. I wondered if this method only regulates the output frame, but not the internal captured frame which is altered by different filters.

So my question is: Does this method immediately take the frame after capture and alter it so that the whole processing process is using the altered frame, or does it only alter the frame right before it is shown on the display?

Can you show me where I can find an answer to this matter, or where you found it?

Here is a minimal:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    javaCameraView =(JavaCameraView) findViewById(R.id.java_camera_view);
    javaCameraView.setMaxFrameSize(240, 180);
    javaCameraView.setVisibility(SurfaceView.VISIBLE);
    javaCameraView.enableFpsMeter();
    javaCameraView.setCvCameraViewListener(this);
}

Sorry for my bad english, hope it is understandeable. Also sorry if this is a stupid question. It is my first time working with OpenCV and Android.
