Hi William, How about this version of this patch: https://patchwork.linuxtv.org/patch/28098/ ? I personally like that one better, it seems clearer to me. This one first sets a bit to vnmp, then make another check and inverts it, whereas that version clearly sets it just for equal colour-spaces. I just never got with proper Sob and (maybe?) authorship.
