Works for me on Plasma Foldder View. Do you see previews in Dolphin?
Comment 4 Patrick Silva 2023-06-21 14:15:46 UTC
yes, I see the previews when opening desktop with Dolphin.
Comment 5 Nicolas Fella 2023-06-21 15:24:28 UTC
Does Neon ship Dolphin based on Qt6? Sounds like the Qt6 variant of kio-extras is missing
Comment 6 Nate Graham 2023-06-21 15:26:10 UTC
It's qt5, so yeah, that does sound like it.
Comment 7 Carlos De Maine 2023-06-26 02:50:07 UTC
there is now a kio-extras6 package but at the moment it does contain many duplicated files with the kf5 version, so your mileage may vary.
Comment 8 Patrick Silva 2023-06-26 13:15:27 UTC
Still no preview for these files:

mkv, mp4, avi and webm videos
pdf document
heic images

Also no preview for files inside a folder.

That would be missing ffmpegthumbs 

> pdf document

Missing kdegraphics-thumbnailers 

> heic images

That sounds like missing heic lib in kimageformats

> Also no preview for files inside a folder.

ffmpegthumbs and kdegraphics-thumbnailers packages are installed, .heic file has preview after re-login.
Comment 11 Nicolas Fella 2023-06-27 10:14:00 UTC
> ffmpegthumbs and kdegraphics-thumbnailers packages are installed

The Qt6 variant is needed
