[lorents17]

good evening!
Please, compile butteraugli under Windows. Thanks!

I have found this threads
https://github.com/google/butteraugl...ment-291049353 — first mingw reference
https://encode.su/threads/2626-New-b...ll=1#post50614 — some more info
https://toster.ru/q/318633 — yours (?) attempt

Have lost some time trying build it with mingw.
Got some useless exes, that just silently exits without any output.

At last I build BA in windows 10 linux subsystem.

Now I can use it like this

bash -c "butteraugli source.jpg guetzli-q95.jpg map.pnm"

both x64 and x86 for windows attached. x86 might crash on big images, for obvious reason (butteraugli needs RAM).

hm, If enlarge an image simply upscaling - PointResize x2

source.png 264.png - 7.191232
source.png 265.png - 6.815086
source-x2.png 264-x2.png - 10.116722
source-x2.png 265-x2.png - 13.422771

The results not only others, but show the opposite.
And in my opinion, the 264 has a better resemblance than 265, that is confirmed by a second test using "PointResize x2"

Butteraugli isn't robust when far from 1.0.

Usable area is between 0 and 1.6, perhaps up to 2.0

Is there any build version available for Linux/Ubuntu

Compiling from source is relatively easy on Linux. IIRC, you only need to install libpng-dev as a prerequisite.
