Hello Caglar, What exactly you set in the bootargs? because I can't get my NTSC/PAL to the 800x480 (or 800x576 perhaps) LCD working.

I got rgba 8/0, 8/0, 8/0, 8/0 for my /dev/fb/0 when fbset -i -fb /dev/fb/0 and I got rgba 0/0, 0/0, 0/0, 0/0 in another 3 framebuffer /dev/fb/1 /dev/fb/2 /dev/fb/3 which I think something is not correct, futhermore the pixclock shows 0 when I set it to 800x576 Any idea what I done wrong? > > Are you using DVSDK_1_30_00_40 or higher ? > > > > > Yes. > > > In DVSDK_1_30_00_40, dvevm demos do not start if resolution is not NTSC > > or PAL, Have you added support for 800x480 prgb ? > > > > > dvsdk_1_30_00_40/demos/dm6446/decode/decode.h : > > /* Scaling factors for the video standards */ > > #define NOSTD 0 > > #define PALSTD 12 > > #define NTSCSTD 10 > > > > > Seems like I forgot somethings.
