Description Alphazo 2014-09-15 09:13:37 UTC 
My Digikam databse is stored on a USB drive and I have been using that setup for years.
I typically start it using : digikam --database-directory /run/media/alpha/PHOTOS-DISK/PHOTOS/Digikam/

But now after few seconds of startup I get a crash.

Reproducible: Always

Steps to Reproduce:
# gdb --args digikam --database-directory /run/media/alpha/PHOTOS-DISK/PHOTOS/Digikam/

Comment 2 Alphazo 2014-09-15 09:27:18 UTC 
I created another bug report similar to this one because 1) the proposed fix doesn't work for me 2) it is marked as "Resolved" (and I don't know how to change the status).

I'm building Digikam at the moment with full debug information so I can post more details.

Thanks
Alphazo
Comment 3 caulier.gilles 2014-09-15 09:29:03 UTC 
The problem is relevant of Phonon KDE component used to play video in digiKam.

A backend used by Photo (GStreamer) crash...

It's not a digiKam problem, but a problem from a 3rd party component on your system.

Comment 4 Alphazo 2014-09-15 09:40:25 UTC 
Thanks for the pointer. I solved the problem after installing phonon-qt4-vlc (the other bug repot mentioned phonon-qt5-vlc).
Comment 5 PCFreak 2014-09-15 18:39:24 UTC 
I think installing

phonon-qt4-vlc or phonon-qt5-vlc is not the fix for this problem.

I had this error similar to others in this thread
0x00007fffb7575a3e in ?? () from /usr/lib/gstreamer-0.10/libgstautodetect.so
So I renamed /usr/lib/gstreamer-0.10/libgstautodetect.so to /usr/lib/gstreamer-0.10/libgstautodetect.so.bak and digikam started without problems.

So I think there is a problem in one of gstreamers components (libgstautodetect.so) which is from

extra/gst-plugins-good
extra/gstreamer0.10-good

I just reinstalled the above with

pacman -S gst-plugins-good gstreamer0.10-good

and digikam works again.

I recently remove archlinuxfr from my pacman.conf because of some problems, maybe some glitch from archlinuxfr caused this? - Any ideas.
Comment 6 caulier.gilles 2016-12-24 09:51:20 UTC 
digiKam 5.4.0 bundles will use QtAV framework instead Qt5Multimedia to thumb
and play video/audio. 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...
