Well, Paul, you're the expert. Are those two correct? If they are, then
I'm right about how the
tokens work and the folks at wikipedia are wrong. I don't care whether the
wikipedia folks are right
or wrong because I don't pay wikipedia any mind because I think wikipedia
is a train wreck. I want
to be right because I want to be knowledgeable so I can help myself and so
I can help other people.
For 4:2:0
its for 4x4 luma block you have 2x2 block chroma
No, no, not 4:2:0. Is my 4:4:1 correct? Is my 4:2:1 correct?
Your attempts to explain it with ascii are comical.
How so, Paul? Pictures is how I think.
--Mark.
