How to display camera preview full screen and maintain aspect raion
I am used QAbstractVideoSurface for getting the camera buffer. My camera resolution is 640*480.
The window is displayed the preview in center part of the screen.
How can I change the preview display area to full screen and maintain the aspect radio.
I am created camera widget and loaded in the qml file.
I tried the calculation of aspect ratio. But the display area is not changed. I struck this for long time.
Its very helpful somebody give the solution for this problem.
