I have changed my Unity default file manager to Dolphin.

Problem: video thumbnails don't show up anymore.
In Nautilus the thumbnails are shown correctly.

How to make Dolphin show thumbnails?

To show thumbnails the Dolphin will need the thumbnail plug in.

In a terminal run

sudo apt-get install ffmpegthumbs

then

sudo apt-get install mplayerthumbs

then

sudo apt-get install kffmpegthumbnailer

then... change in dolphin settings as says in user26687's answer... works for me kubuntu 14.04lts in laptop n4010 dell

  • Installed as suggested. A new menu item in dolphin appeared (Video Files (ffmpegthumbs)). However, thumbnails are still not generated :( – user3804598 Oct 7 '18 at 14:47

Now in Ubuntu 15.10 I needed another package for thumbnails to show:

sudo apt-get install kio-extras

  1. Install the following packages: ffmpegthumbs mplayerthumbs kffmpegthumbnailer kio-extras
  2. Restart Dolphin
  3. Settings > Configure Dolphin > General > Behavior > View > Use common properties for all folders, OK
  4. Press the "Preview" button
  • kio-extras did the trick for me, otherwise I couldn't see anything under General > Previews – sdkks Sep 23 '17 at 22:13
