Davinci supports 4 hardawre planes, out of which 2 are OSD( supoprt RGB565 graphics) and the other two support YCbCr data. If you want to write RGB data to the driver you can use either OSD0 or OSD1 instead of the Video planes. This could be done by using /fb0 and /fb2 instead of /fb1 or /fb3.

I am using the DM6446 DVEVM, with a digital LCD connected, and using the decode_hd demos. Demo works fine in the standard mode where you pass a h.264 frame to the DSP, it returns back YCbCr, that is passed to the davincifb. Then the VENC automatically converts it to RGB before displaying on the LCD. I have written an RGB conversion codec. I want to test the conversion by writing to the davincifb and have it display to the LCD.
