Description Jim Shipman 2014-01-18 05:18:33 UTC 
Fedora 20 Gnome - digikam compiled from source 4.0.0-beta2 tarball with debugfull.
ffmpegthumbnailer works perfectly in a terminal for all my video formats.  Photos thumbnail correctly.  Nautilus correctly thumbnails all video files.

Steps to Reproduce:
1. Start digikam

3. 
Actual Results:  
No Thumbnails for video files

Expected Results:

Does Dolphin display them if Video Previews are enabled?
Comment 2 caulier.gilles 2014-01-21 12:20:23 UTC 
No reproducible here under Mageia 3 with digiKam from git/master (next 4.0.0-beta3)

There is no video thumbnailer in digiKam.

digiKam just delegate to KDE thumbnailer to task to generate thumbnails from video files.

Check your system installation/settings, and respond to comment #1 please...

Note : under Mageia3 this package is installed :

ffmpegthumbs - Video thumbnail generator for KDE4 file managers​                                                                                                                         
FFmpegThumbs is a video thumbnails implementation for KDE4 based on FFmpegThumbnailer.

This thumbnailer uses FFmpeg to decode frames from the video files, so supported video formats depend on the configuration flags of ffmpeg.

This thumbnailer was designed to be as fast and lightweight as possible.

Fedora 20 Gnome, digikam 4.0.0-beta2 - My videos now have thumbnails except for some AVI files (mjpeg inside) that were created by a very old canon camera.  Ffmpegthumbnailer also does not create thumbnails for these files although they play perfectly on my system so there must be a codec for them.  Looks like my problem was not system wide, but just a few files of a particular type.
I've been playing around with ffmpeg to see if I can convert these files but so far now joy.  Mencoder  does convert them, but I still can't get ffmpegthumbnailer to work even with the converted files (to mov format).  Original and converted files play perfectly.

Thanks Jim for the update. So can we close this bug?
Comment 6 Jim Shipman 2014-01-21 22:23:03 UTC 
Yes.  As far as I'm concerned you can close this (non) bug.

Since digiKam 5.2.0, we use QtAV/FFMPeg framework to render video thumbnails.
