Bug ID: 468884
Summary: New Regression (?): Gwenview Incompatibility With Some
Self Made libaom avif Photos [sxiv opens them with no
problem]
Classification: Applications
Product: gwenview
Version: 22.12.2
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general

Gwenview and Dolphin Fail on This Self Made Avif Photo. Sxiv opens it with no
problem.
SUMMARY
***
Gwenview can open some avif made photos, but on some it fails to open. Dolphin
can't generate thumbnail. Sxiv has no problem at all.
***
STEPS TO REPRODUCE
1. Make a photo with Nicon D810 [tiff, 7380x4928]
2. Import with dcraw [9.28]
3. Convert it to intermediary PNG with graphicsmagic [$ gm convert]
4. Compress your PNG photo to avif [av1] with libaom:
$ avifenc -c aom -j all -d 8 -s 0 --sharpyuv -a aq-mode=2 -a sharpness=0
myphoto.png -o myphoto_compressed.avif
5. Result: Size reduction from 209M [tif]/164M [png] to 506K [avif].
OBSERVED RESULT
1. Dolphin has no thumbnail [unlike my other slef-made avif photos]
2. Gwenview can't open this avif photo
3. sxiv has absolutely zero problem with this photo
EXPECTED RESULT
Stop adding endless functions to gwenview. Focus on photo displaying. Make it
high quality photo viewer just like sxiv. Do one thing, one thing only and do
it good. Gwenview should be photo viewer not editor. Its not GIMP nor
Darktable. Make it robust photo viewer.
