Description yellowsblog 2011-09-09 21:40:27 UTC

Version:           1.9.0 (using KDE 4.6.2) 
OS:                Linux

Video file thumbnails are not generated for all video files, even though they were taken on the same day. I have DV codec in avi 90% get thumbnails, h264 in mp4 50% get thumbnails, h264AVC in MOV 50% get thumbnails, of the files that don't get thumbnails, some files get the clapper board icon instead, others just a blank space.

Also some video files get the wrong thumbnail too. 

Reproducible: Always

Steps to Reproduce:
Importing via the Import menu item


Expected Results:  
Expect to see all thumbnails. :-)

OS: Linux (x86_64) release 2.6.38-11-generic
Compiler: cc

To support Video thumbnails under Linux, please install "mplayerthumbs" package.

I already have mplayerthumbs installed, I've already told dolphin to build for maximum of 9999mb files although its buggy and resets its self to 1809mb, I left machine rebuilding thumbs for hours I've reimported 2TB of video files only 80% make thumbs As a test I set Dolphin to add film strip effect to edge of plugins and rebuild all thumbs for 2TB of video files it took hours and I now have a few extra thumbs with film strip and the majoritu don't so Digikam hasn't even rebuilt all thumbs at all.

I'm a Gnome user but today I installed a complete KDE Desktop and tried under KDE desktop apart from being inredibly sluggish to use Digikam failed again to rebuild all thumbs.

digiKam 5.4.0 will have a video thumbnailer based on QtAV framework. We do not
use KDE video thumbnailer anymore...
