Hi everyone...
i'm new, and i am here to ask you a simple question:
i am developing on a PowerPC embedded processor (MPC823) and i want to run
an X-server on its video-controller that can handle YCbYCr data format
(4:2:2) in memory. It simply stores 2 bytes per pixel, depending of even of
odd position, YCb or YCr.
I ported GGI and XGGI on my board, but the problem is that XGGI doesnt use
GGI primitives, but its directbuffer feature, that permit the program access
directly to the memory buffer that it supposes to be a RGB framebuffer, not
YCbYCr.
I heard of KGI and its PhoeniX & X11 but i dont know how they works togheter
and if they access directly to the memory or if they use other library
primitives.
Have you any hint for me?
Thanx in advance.
- may the pinguin b with u -
Have a nice day,
Paolo Scaffardi.
