Answer 1

if you want to rotate the preview output, try this:

public void surfaceChanged(SurfaceHolder holder, int format, int width, int height)
    {            
        if (isPreviewRunning)
        {
            mCamera.stopPreview();
        }

        Parameters parameters = mCamera.getParameters();
        Display display = ((WindowManager)getSystemService(WINDOW_SERVICE)).getDefaultDisplay();

        if(display.getRotation() == Surface.ROTATION_0)
        {
            parameters.setPreviewSize(height, width);                           
            mCamera.setDisplayOrientation(90);
        }

        if(display.getRotation() == Surface.ROTATION_90)
        {
            parameters.setPreviewSize(width, height);                           
        }

        if(display.getRotation() == Surface.ROTATION_180)
        {
            parameters.setPreviewSize(height, width);               
        }

        if(display.getRotation() == Surface.ROTATION_270)
        {
            parameters.setPreviewSize(width, height);
            mCamera.setDisplayOrientation(180);
        }

        mCamera.setParameters(parameters);
        previewCamera();                      
    }
