Perfect, thanks Michael. Let me check those samples out.

Here is a comparison of what I was described in the commit log.

The naming of the files images are
${pixfmt}_${scaled}_${in_range}_${out_range} for with/without the patch:

My concern was the yuv444p10_${scaled}_jpeg_mpeg (explicit settings), give
different results than the implicit yuv444p10_unscaled_unspec_mpeg ones for
high bit depth. And the high bit depth is results are in general different
than the low bit depth ones.
