For speed, I agree with Alex. Also, nano-X has a function,
GrOpenClientFramebuffer(), which when used with
GrGetWindowFBInfo(), will return the hardware
framebuffer address of the window's upper left
corner. In this way, you get the speed of direct access,
with the benefits of the other aspects of nano-X,
including window frames, etc.
Regards,
Greg
: I think you don't need any GUIs, just directly output frames from webcam
to the framebuffer of linux kernel. Nano-X also likes many GUIs on Embedded
linux system which output images to framebuffer. So, I think GUIs don't have
any help for your webcam unless you really need a GUI for interaction with
User. FYR!
