I installed Ubuntu 16.04 and installed dolphin (15.12.3) + FFMpegThumbs so that I can see thumbnails of videos but when I went to the previews the box was just blank.

ffmpegthumbs 4:15.12.3-0ubuntu1 is buggy and unpacks ffmpegthumbs.so to the wrong location. Until the package is fixed a workaround is to link the files to the correct location:
sudo ln -s /usr/lib/x86_64-linux-gnu/plugins/* /usr/lib/x86_64-linux-gnu/qt5/plugins/
This works on my installation of Kubuntu 16.04 LTS. By the way ffmpegthumbs needs kio-extras to work (should be installed on Kubuntu by default as a dependency of kubuntu-desktop).

suo apt install kio-extrassolved the problem for me on 17.10.1– jrouquieCommented Jan 17, 2018 at 10:15 -
@JulianLai: The location specified by
ffmpegthumbsused to be correct until a new location was introduced by QT5 and used by the new version of Dolphin based on QT5. Commented Jan 17, 2018 at 10:46 -
@jrouquie:
kio-extrasis always needed for Dolphin previews, this is mentioned in my answer. What really happened is that the bug in ffmpegthumbs was fixed. The workaround described in my answer is not necessary anymore with newer versions of Kubuntu. Commented Jan 17, 2018 at 10:48 -

sudo apt install kio-extraswas still needed to solve the problem on Ubuntu 18.04 (not Kubuntu, where I'm glad to learn it's installed by default).– jrouquieCommented Jun 11, 2018 at 9:00
ffmpegthumbsandkio-extrasinstalled on my system and it still doesn't work. FFMpegThumbs is enabled in the Dolphin options.
