              The camera object itself seems to be null. Are you sure it's initialized correctly ?

                Ok. if i have not initialized it, can you help me on how to initialize it?
                I have done the initialization as below:

                    mCamera = new QCamera(this);
                    mCameraViewFinder = new QCameraViewfinder(this);
                    mCameraImageCapture = new QCameraImageCapture(mCamera,this);
                    mCamera->start();

                  It's not your mCamera object that is null, it's your camera object.

                      It's your own custom class, how can I know where you use it or how you use it ?

                          Then don't create a new QCamera each time you change the resolution.
