hi Robin,
Indeed, there is nothing trivial to make SurfaceFlinger to switch
between /dev/graphics/fb0 and /dev/graphics/fb1. But you can still
implement SoC/hardware specific libopencorehw and liboverlay utilizing
/dev/graphics/fb{1,2}, then image/video could be rendered
independently in these graphical overalys instead of base plane,
/dev/graphics/fb0 .
There is a reference implementation:
