To make this more clear: RGB565 is little endian byte order, whereas RGB565X is big endian. If you are going to process 16bpp on a big endian machine (powerpc for example), you should pick the RGB565X version. > Shouldn't the depth for formats V4L2_PIX_FMT_YVU411P and > V4L2_PIX_FMT_YUV411P be 12 bits (not 16 what the videodev.h says)?

IIRC yes, some kid of hardware did that, but forgot which one ... Gerd -- Weil die späten Diskussionen nicht mal mehr den Rotwein lohnen. -- Wacholder in "Melanie"
