I have Ubuntu 16.04 LTS and I've manually installed Ubuntu 18.04 LTS. Everything looks fine except video thumbnails. How to solve this?

  • Did you choose the "minimal installation" option instead of "normal installation" as shown here: omgubuntu.co.uk/wp-content/uploads/2018/04/…? – pomsky May 10 '18 at 18:15
  • I choose normal installation. – Vikas May 11 '18 at 7:51
  • Upgraded to ubuntu 18.04 from 16.04 recently, same issue no thumbnails in my list view of folders and never checked icon view. I did everything except for some commonsense then bumped on following reddit.com/r/Ubuntu/comments/8di3ce/… and that seems to be my issue, icon view thumbnails always work and in list view I need to zoom to 150%. – shyam Sep 14 '18 at 5:47

Install FFMPEG Thumbnailer-

sudo apt install ffmpegthumbnailer

Then close and reopen file manager. Thumbnails for most video files should generate now.

However, if it's still not working then open file manager, go to your home folder if you're not already there (Home folder is usually the folder which contains Downloads, Documents, Photos etc folders).

Press Ctrl+H, enter into the folder named .cache. Then enter in the folder thumbnails.
Delete everything in there. Restart your PC.

  • No need to restart my PC; quitting and restarting Nautilus was enough – smac89 Apr 17 at 2:32

I have tried the HattinGokbori87's solution but it failed, and I found another way to soluted it.

First I install the HattinGokbori87's suggested package like this:

sudo apt install ffmpegthumbnailer

Then I restart the computer but there I still can not see the video's thumbnails in the file manager, so I try to install the another package like this:

sudo apt install gstreamer1.0-libav

Ok, clean up the directory like this:

rm -r ~/.cache/thumbnails/fail

It works!

file manager show

enter image description here

maybe this will help others whose ubuntu 18.04 can not show the thumbnails of video.

reference this if you ubuntu 18.04 thumbnails still not work


Install following packages


sudo apt-get install ffmpeg ffmpegthumbnailer gstreamer0.10-ffmpeg

Then edit the following file with respective content

sudo vi /usr/share/thumbnailers/totem.thumbnailer

just paste the following lines

[Thumbnailer Entry]
Exec=ffmpegthumbnailer -s %s -i %i -o %o -c png -f -t 10

and finally restart your machine and see.
