 |
|
Today I updated to the latest stable kde-apps/dolphin version, lo and behold, there are no more video thumbnail previews in dolphin and the use flag is no longer there.
Anyone knows how can I generate video thumbnail previews in dolphin now? |

I just did and video thumbnails are back, so thanks.
It turns out this package was pulled by the thumbnail use-flag in dolphin which was dropped from this version and so that package was removed upon clean my system after the upgrade.
installing it now, surprisingly, did cause video thumbnail previews to return, even though I remembered, the same didn't work before without dolphin having the thumbnail use-flag available.
Edit: another package that was removed and is helpful in generating (pdf) thumbnail previews is kde-apps/thumbnailers |

If you don't have these packages installed, dolphin is warning you about that:
| Code: | * For compress/extract and other actions install kde-apps/ark:5
* For crypto actions install kde-apps/kleopatra:5
* For video file thumbnails install kde-apps/ffmpegthumbs:5
* For graphics file thumbnails install kde-apps/thumbnailers:5
* For 'Share' context menu actions install kde-frameworks/purpose:5 |
The meta packages pull them in automatically for you, if you install only dolphin, you need to watch out for these messages. |

emerge --depclean may be the causer. I've just updated my system and got it:
| Code: | emerge --depclean
* Always study the list of packages to be cleaned for any obvious
* mistakes. Packages that are part of the world set will always
* be kept. They can be manually added to this set with
* `emerge --noreplace <atom>`. Packages that are listed in
* package.provided (see portage(5)) will be removed by
* depclean, even if they are part of the world set.
*
* As a safety measure, depclean will not remove any packages
* unless *all* required dependencies have been resolved. As a
* consequence of this, it often becomes necessary to run
* `emerge --update --newuse --deep @world` prior to depclean.
Calculating dependencies... done!

You should add these packages in world file with emerge --noreplace kde-apps/ffmpegthumbs kde-apps/thumbnailers or create a sets.
For example in my system I don't use kde-apps/*-meta packages and I created my own set
| Code: | # kdecore
kde-apps/dolphin
kde-apps/konsole
kde-apps/kwrite
# kdeutils
kde-apps/ark
kde-apps/kcalc
kde-apps/kcharselect
kde-apps/kwalletmanager:5
kde-apps/sweeper
kde-apps/print-manager
# kdepim
kde-apps/kmail
kde-apps/korganizer
kde-apps/kontact
kde-apps/kdepim-addons
# Others
kde-apps/dragon
kde-apps/kate
kde-misc/kdeconnect
kde-apps/yakuake
x11-misc/appmenu-gtk
kde-misc/plasma-pass
kde-misc/latte-dock |

Still didn't get a result after re-emerging kde-apps/dolphin kde-apps/ffmpegthumbs kde-apps/thumbnailers kde-misc/openofficeorg-thumbnail kde-frameworks/purpose.
What worked was to rename all directories and files that have name "dolphin*" in ~/.cache ~/.config and ~/.local and restart dolphin
| Code: | cd ~/.config
$ find . -name "dolphin*"
./dolphinrc
./session/dolphin_dolphin_dolphin
./session/dolphin_255155f2e-1dc7-4276-9e96-9e9c77a09bcc_1616293945_371144
./session/dolphin_29dafbf37-6aad-4b90-b828-b55f7cb3dc15_1616232719_188572
$ mv dolphinrc dolphinrc-0
$ rm session/dolphin*
cd ~/.cache
$ find . -name "dolphin*"
./dolphin
$ mv dolphin dolphin-0
cd ~/.local
~/.local$ find . -name "dolphin*"
./share/kxmlgui5/dolphin
./share/kxmlgui5/dolphin/dolphinui.rc
./share/dolphin
mv share/kmxlgui5/dolphin share/kmxlgui5/dolphin-0
mv share/dolphin share/dolphin-0 |
Restart dolphin and enjoy the thumbnails.  |
