How to convert YCBCR422 to RGB with opencv?

I’d like to convert YCbCr422 to RGB but can’t find the correct color code for that?Can you help me?

might this be a two-plane format? then cvtColorTwoPlane

if not, there are all the codes. OpenCV: Color Space Conversions

chroma-subsampled formats are among these. look for any 422 mentions.
