(I should have said 4:2:0) The issue is that the small offset error in the code is small compared to the chroma subsampling.

No, that is a
pseudo example of how you
might be able to code it up in 2.6. Post 38 is an academically pure version for 2.5, given the trouble I had building a test pattern to actually see the error, I do not believe it is worthwhile.
@Fizick,
As above, I do not believe there is anything significant to worry about. But we are all a little anal about getting this stuff right, so it is good to document where we are wrong and how to eventually fix it.
@henryho_hk,
Yes, I guess if you are sufficiently motivated you could use UtoY to make a sightly faster version.
