I'm using JavaCameraView. This is Android application and it supports both Portrait and Landscape modes. I am able to set correct preview and picture size for camera BUT for some reason rotation parameter is ignored and preview is only OK in landscape mode. This is the code I use to set orientation:
private void setCameraDisplayOrientation(Camera camera) {
int cameraId = getCameraId();
android.hardware.Camera.CameraInfo info = new android.hardware.Camera.CameraInfo();
android.hardware.Camera.getCameraInfo(cameraId, info);
WindowManager windowManager = (WindowManager) getContext()
.getSystemService(Context.WINDOW_SERVICE);
int rotation = windowManager.getDefaultDisplay().getRotation();
int degrees = 0;
switch (rotation) {
case Surface.ROTATION_0:
degrees = 0;
break;
case Surface.ROTATION_90:
degrees = 90;
break;
case Surface.ROTATION_180:
degrees = 180;
break;
case Surface.ROTATION_270:
degrees = 270;
break;
}
camera.setDisplayOrientation((info.orientation - degrees + 360) % 360);
}
Obviously I can rotate picture in onCameraFrame but it looks like waste of resources to me. Does OpenCV camera even support orientation other than Landscape?
