This is probably FOURCC_YUY2, FOURCC_YUNV and FOURCC_V422 (they're
all the same). If it's correct, then it's the one you want to use
because the conversion from the decoder pictures to this format is

This is probably FOURCC_UYVY, FOURCC_Y422 and FOURCC_UYNV.
Note: one of my interpretations for B_YCbCr422 or B_YUV422 is wrong,
but I don't know which one. My bet is that the one for B_YUV422 is

This might be FOURC_YV12, which would be cool because it's the output
format of the video decoder.
