Interesting, so to make two tiles, would you set tile-row to 2 and leave tile-column at 0 (or vice versa)?

[edit]
Just did some research, the config params are log2 values.

e.g.
param -> actual
1 -> 2
2 -> 4
3 -> 8
4 -> 16

I have no idea WHY this is the case (seems to be in order to use the same syntax as libaom)...

Did a quick sanity check, using -tile-columns 1 gave slightly better metrics than -tile-rows 1, but that's just a couple quick tests. It will likely be content dependent based on motion.
