avfilter : color_range of frame incorrectly flagged as limited

[mvignali]

Summary of the bug:
Full range frame (at least for rgb)
are send to filter, in limited range.

How to reproduce:

./ffmpeg -i ./fate-suite/mov/mov_alpha_premult.mov -vf unpremultiply=inplace=1 resStraight.png -y

Same thing appear using png as input for example.

Well, yes, ffplay.exe -i mov_alpha_premult.mov -vf extractplanes=r

shows the difference with RGBA png file.

I will point out that alpha is also not bitperfect between the two.

Lol, here is the fix:

though apparently there is some metadata there? https://ffmpeg.org/pipermail/ffmpeg-devel/2018-March/226799.html

Is this still an issue??
