Recently we have ported a video driver to the MPC823 using the video encoder AD7176. The problem is, that the pixels data in the framebuffer must have the YUV or Y-Cb-Y-Cr-Format which is rarely used, at least I have not found any support in Linux or Microwindows. You can find the port on our linux-2.4 CVS tree (see http://www.denx.de/re/linux.html). Check for "arch/ppc_8xx/video823.c" and "drivers/video/fbcon-yuv.c". Hope it helps, Wolfgang. ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
