Same as the other liveview example, but displays in color.
Obviously you want to use a camera that has a color mode like BGR8Packed
OpenCV is expecting color images to be in BGR8Packed by default. It can work
with other formats as well as convert one to the other, but this example
just uses its default behavior.
