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: http://gitorious.org/0xdroid/hardware_omap3_libopencorehw Regards, Jim Huang (jserv) http://0xlab.org/ --~--~---------~--~----~------------~-------~--~----~ unsubscribe: android-porting+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-porting -~----------~----~----~----~------~----~------~--~---
