script to help with selecting the best cover art

I’ve created this little scriptlet to help me select the best of two files, since sacad usually finds the better image, but sometimes finds the wrong image.

So use find . -name 'cover.jpg' -size -100 -exec mv '{}' '{}.toosmall' \; to rename all too small cover files cover.jpg file to cover.jpg.toosmall, and then run the script.

I don’t know if this is useful to anyone, perhaps just something to get you started. Currently works great with sway (the window manager), see screenshot.

#!/bin/zsh
swaymsg 'for_window [instance="feh"] floating disable'
swaymsg 'no_focus [instance="feh"]'

find . -name 'cover.jpg.toosmall' | while read dir; do
    (
        cd "${dir%/cover.jpg.toosmall}"
        pwd
        if [[ -e cover.jpg ]]; then
            # feh -D 1 cover.jpg.toosmall cover.jpg
            feh -w cover.jpg.toosmall cover.jpg &
            swaymsg focus floating
            echo -n 'Like the big one? [y/N]'
            read -sk1 a
            echo
            pkill -u $USER feh
            case $a in
                y|Y)
                    rm cover.jpg.toosmall
                    ;;
                n|N|*)
                    rm cover.jpg
                    mv cover.jpg.toosmall cover.jpg
                    ;;
            esac
        else
            mv cover.jpg.toosmall cover.jpg
        fi
    )
done
swaymsg 'for_window [instance="feh"] floating enable'

Sacad 2.6.0 has been released, with the added Discogs source, and a few improvements around result sorting with regard to source quality.

I am closing this issue.

For next “result quality” issues, instead of overly broad problems, next time please open issue with:

• problematic query with exact Sacad parameters
• cover that is downloaded
• cover that should have been downloaded instead

For Arcana / Cantar De Procella, Sacad correctly identifies https://lastfm.freetls.fastly.net/i/u/300x300/0d35404b4cab1aaf95ac5714eb7398d6.jpg as the reference image, but can not use it directly because it is 300x300 and you requested 900x900 with a 25% delta tolerance (the default), so 675x675 minimum.

The result that is downloaded, https://e-cdns-images.dzcdn.net/images/cover/58347ef9ea58c0a7698ed39242695b57/1000x1000-000000-80-0-0.jpg, is correctly identified as NOT similar to reference (using a perceptual hash), you can see it if you pass -v debug:

DEBUG [Cover] DeezerCoverSourceResult 'https://e-cdns-images.dzcdn.net/images/cover/58347ef9ea58c0a7698ed39242695b57/1000x1000-000000-80-0-0.jpg' is NOT similar to reference

But unfortunately this is the best cover available that match set search criterias.

If you want the correct result, with a smaller size only if needed, pass -t 75 which increases size toleance, see sacad -h:

  -t SIZE_TOLERANCE_PRCT, --size-tolerance SIZE_TOLERANCE_PRCT
                        Tolerate this percentage of size difference with the target size. Note that covers with size above or close to the target size will still be preferred if available
                        (default: 25)

I have not looked at your other examples, but I suspect this is often the same issue.
