Description Erik Kj 2007-04-11 17:52:26 UTC

Version:           0.9.0 (using KDE 3.5.5-3.fc6, Fedora Core release 6 (Zod))
Compiler:          Target: i386-redhat-linux
OS:                Linux (i686) release 2.6.19-1.2895.fc6

When there are a lot of avi-files in the directories, the startup time is so slow that it is not possible to use digikam, specially when these avi-files are rather large

Erik,

Are you installed avi file library to view these video files ?

Comment 2 Erik Kj 2007-04-12 03:29:03 UTC

Yes I am using fc6 together with the livna rpms, and I have 
kdemultimedia-extras-nonfree installed so that each avi shows its first frame as icon. The problem basically started when my daughter bought a camera with very high quality avi's and sent them to us. I cannot run digikam on my basic directory with pictures and avi's any more

This bug might be related to

http://bugs.kde.org/show_bug.cgi?id=149267
http://bugs.kde.org/show_bug.cgi?id=145497
which has beeen fixed.

Could you try with
- Exiv2 0.15

and report back? 

Thanks a lot in advance,

Arnd

All the bugs mentioned in #c3 have been solved.
 
Erik, could you try again with current versions and see
if this problem is fixed as well?

Thanks a lot in advance,

Arnd

I confirm. AVi support work fine here too (Mandriva 2008.1 and 2009.0)

Comment 9 caulier.gilles 2016-12-22 13:35:24 UTC

digiKam 5.4.0 bundles will use QtAV framework instead Qt5Multimedia to thumb
and play video. The Slideshow tool will also support video as well.

QtAV use ffmpeg codecs. It's multi-platform and will always available in
OSX, Windows and Linux bundles that digiKam team provide.

For Linux packagers, you will need to turn on video support at compilation time
and solve QtAV dependencies...

The screenshot here :

... is based on pre-release of AppImage 64 bits Linux bundle, just recompiled
and post to GDrive for testing.
