I am new here. I wanted to implement android framebuffer zooming. Android is rendering it's contents into fb0. AFAIK IPU is passing fb0 to the display panel (LVDS). I know also that it is capable of scaling.
So I wanted to setup IPU so that it selects part of the fb0 scales it to the full HD resolution and passed onto LVDS. The IPU API is a bit complicated (driver API) and the example included operates on file image data not on a living framebuffer, so it didn't help me.
Is it possible to do the realtime framebuffer scaling and how?
