Comment (by richardpl):

 Doing yuv444p16 conversion from rgb48 is very bad, it is automatically
 done by scale filter. There is no output support for gbrp16 so you can not
 use scale filter to convert packed rgb48 to planar gbrp16 one, which
 zscale and zimg needs. So that is unrelated bug but I understand how you
 feel. Will try to make output support for gbrp16 in swscale to work.
