public function video_localcommand::getDimensionParameters in Video 6.5

Function determines the dimensions you want and compares with the actual wxh of the video.

If they are not exact or the aspect ratio does not match, we then figure out how much padding we should add. We will either add a black bar on the top/bottom or on the left/right.

The output width and height are divisible by two
