Description pmargeti34 2021-12-12 10:30:18 UTC 
SUMMARY
file open/save dialog can't configure which plugins should be used for previews from GUI, and as such it doesn't display previews for video container files (such as webm, mkv, avi...)
this can be remedied by editing .config/kdeglobals and adding the following line:
```
Plugins=appimagethumbnail,audiothumbnail,fontthumbnail,ffmpegthumbs,djvuthumbnail,directorythumbnail,kraorathumbnail,opendocumentthumbnail,ebookthumbnail,windowsexethumbnail,imagethumbnail,windowsimagethumbnail,exrthumbnail,jpegthumbnail,svgthumbnail,comicbookthumbnail
```
which is basically copied from dolphin's config file under the [PreviewSettings] section.

File dialog should either have preview plugins configurable via GUI or read the dolphin's preview list.

It should probably read from Dolphin, yeah.
Comment 3 pmargeti34 2021-12-15 05:25:21 UTC 
Come to think of it, there's also configurable plugins for the desktop display. So that's 3 locations for the same setting. I believe I speak for the common user when I say that when I specify I want previews for video files, I want the previews for video files on my desktop, in my file manager and my open/save dialog. Perhaps this setting should be unified and moved to an appropriate category in the settings (workspace behavior?)

Yes, I agree.
