            Bug ID: 339092
           Summary: Segmentation Fault when launching Digikam
           Product: digikam

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/

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

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.

Thanks for the pointer. I solved the problem after installing phonon-qt4-vlc
(the other bug repot mentioned phonon-qt5-vlc).

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.

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...
