thumbnail for videos in nautilus

edit

In nautilus the image/video previews are generated by the app totem-video-thumbnailer Check if you have it install by running:

ls -l /usr/bin/totem-video-thumbnailer

Second, you need the proper codecs installed.

For 32 bit systems you need:

yum -y install gstreamer-plugins-bad gstreamer-plugins-bad-free-extras gstreamer-plugins-bad-nonfree gstreamer-plugins-ugly gstreamer-ffmpeg

whereas for a 64 bit system you need:

yum -y install gstreamer1-libav gstreamer1-plugins-bad-free-extras gstreamer1-plugins-bad-freeworld gstreamer1-plugins-base-tools updates gstreamer1-plugins-good-extras gstreamer1-plugins-ugly gstreamer1-plugins-bad-free gstreamer1-plugins-good gstreamer1-plugins-base gstreamer1

In order to install these codecs you need to install the RPM fusion repositories.

IIRC you need gstreamer-plugins-bad from RPMFusion

I found that the default maximum file size for generating previews was 1 MB on my system. Since many videos are bigger than that, I wasn't getting thumbnails for them. To solve this problem, go into the file manager, Edit> Preferences> Preview> Change "Only for files smaller than" to something bigger.
