Platform: IMX6 Android 4.4.2
I would make pixel wise operation on framebuffer (/dev/graphic/fb0, how to modify the driver? I want to resize, pan and rotate the content of framebuffer.
I have a Unity application program which will generate 1920x1080px60 LVDS output but it need to be warped, and I think software de-warping is an available solution.
Should I modify framebuffer driver directly? If I could look into some code examples that would be great.
