Fix Video Thumbnails in Dolphin 15.08.1 (KDE 5.17.0) in Fedora 23

When updating KDE in my Fedora 23, I lost the video previews in Dolphin. Even after installing ffmpegthumbs did not work.

So here is the solution:

sudo cp /usr/share/kde4/services/ffmpegthumbs.desktop /usr/share/kservices5/
sudo cp /usr/lib64/kde4/ffmpegthumbs.so /usr/lib64/qt5/plugins/

You need to have installed ffmpegthumbs for this to work, to install it:

sudo dnf install ffmpegthumbs

And you need to enable the video preview again in Dolphin.

Video preview in Dolphin with kffmpegthumbnailer

kffmpegthumbnailer it’s faster than mplayerthumbs.

To install it, we need to:

yum install kffmpegthumbnailer

To enable it in Dolphin:

Preferences -> Configure Dolphin -> General -> Previews -> Video Files (kffmpegthumbnailer)

Check that option, and it’s done, now we have a really fast preview of our video files in Dolphin.
