I have ubuntu 13.04 and many of my videos do not show thumbnails whereas some do, they are all Mp4 formats including the ones that do show thumbnails.
Is there a way to make all videos show thumbnails?
The ones that do show them were on my old operating system when i had windows 7 so after movinng them from pc to external hardrive to pc (with new os, ubuntu 13.04) the thumbnail remained, whereas new videos do not show the thumbnail.
First install:
sudo apt-get install ffmpeg ffmpegthumbnailer gstreamer0.10-ffmpeg
then
sudo gedit /usr/share/thumbnailers/totem.thumbnailer
replace contents with following:
[Thumbnailer Entry]
TryExec=ffmpegthumbnailer
Exec=ffmpegthumbnailer -s %s -i %i -o %o -c png -f -t 10

Change the permissions of folder ".cache/thumbnails" in home directory by following command:
sudo chmod 777 -R .cache/thumbnails
Delete the files inside folder .cache/thumbnails/fail
Try this. Install libxine1-ffmpeg, it might be needed for some thumbnails. To install, just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:
sudo apt-get install libxine1-ffmpeg
From: Gnome 3 not displaying thumbnails?
Had the same problem with Ubuntu 13.10 - Gnome3. Solved it deleting whole folder thumbnails in /.cache and remaking it.
1) Disable preview in nautilus by opening home folder, Edit-> Preferences-> Preview.
2) sudo rm ~/.cache/thumbnails
3) Empty trash can
4) sudo mkdir ~/.cache/thumbnails
5) Reboot
6) Enable preview, again home folder, Edit-> Preferences-> Preview.
Done.
Worked for me.
