How can I capture two framebuffer which overlaid?

[호영노]

I set the fb0 to UI area, and fb1 to streaming the camera.

so when I execute the application, I can see the real time camera view and my UI pictures.

I can capture and save the file each framebuffer but I have no idea about the real-lcd's picture.

How can I capture the overlaid framebuffer??

You can render directly to overlay plane by setting enviroment varialbe

FB_FRAMEBUFFER_0=/dev/fb1
