[FFmpeg-devel] [PATCH] avfilter: add zscale filter

[Moritz Barsnick]

"I'm only here for the nitpicking." I noticed quite a lot of errors in
the various documentation recently, and joined the list to submit
patches. Let me start though by noting my observations here:

> +  --enable-libzimg         enable zimg, needed for zscale filter [no]

So, is it "z.img" or "zimg"?

a) This is identical to using iw?
b) Width, really? Even if used for the variable "h", "height"?
