how to use to implement overlay in hardware imx6dl

[wangds]

Now I used imx6Dual. Fb0 is available at present, and FB1 is not specified. At present, it is hoped to implement overlay on the screen. A bottom layer is used to display the video stream information from camera through device node , and an upper layer displays the normal interface in QT.What should I do?
