Please make this list more compact, make use of several items per line.

Ok. I will apply the patch soon.

You sure that packed and semi-planar formats like nv21 work with filter?

Yes, because every plane they use have continous data and every component is calculated equally into the sum of absolute differences.

Applied.

Marton
