I am very new to OpenCV, trying it for the first time. I ran the Tutorial3CameraControl, camera preview was fine portrait and full screen, when I integrate the same code in my project, I somehow get the camera in landscape mode and its not full screen. I get it this question has been asked quite a few times, but none of the solutions were helpful. I want my application to open up org.opencv.JavaCameraView in full screen portrait mode. Could someone please help me?
