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.
Video thumbnailers for the Dolphin:
:~$ apt-cache show ffmpegthumbs
