Any idea what package or setting I'm missing in KDE for video thumbnails in kdialogue (file picker)? Video thumbnails/previews work fine in Dolphin on desktop, but when using kdialogue as a file picker for things like posting here it won't show any thumbnail for video files.
CachyOS, ffmpegthumbnails and ffmpegthumbnailer are both installed, kio-extras, kdesdk-thumbnailers
