Comment (by Timo R.):

 nvenc/nvdec use P016/P216 for historical reasons.
 When they were implemented, P012 and P212 didn't exist.
 So now migration to those is a bit complicated, since changing the output
 format is a breaking change.

 And there still is a total lack of support for the 10 and 12 bit formats
 that nvdec outputs (and nvenc accepts for input) for 4:4:4, so that's
 always mapped to AV_PIX_FMT_YUV444P16, even though the LSB are always 0
 (or ignored in case of nvenc).
