Description Damien Couroussé 2018-02-14 10:30:21 UTC
hello,

I am a Debian v9 user, with digikam 5.3.0-1.
 
Digikam does not display video thumbnails on my setup.  The FAQ says to install packages libarts1-xine and/or libxine-extracodecs, but these packages are no longer available on recent Debian or Ubuntu distributions.

Which package should I install?  

thanks,
Damien

Which FAQ ? from the Web Site ?

video thumbnail => we use qtAv => you need ffmpeg codecs.

video support is optional at compilation time. Check in Help/Components Info dialog if this feature is listed. If not, report this problem as UPSTREAM to Debian team.

NAyway, you want video thumbnails support in all case. Forget the DK from your system, and use the AppImage Linux bundle that we provide in download page.

As far as I understand, ffmpeg codecs are properly installed on my system.  Or do I miss another package?

$ dpkg -l ffmpeg*

I have downloaded version 5.8.0 in the AppImage Linux bundle, and video support works fine.  I will report the issue to the Debian team.

Thank you Gilles for your feedback,
and thank you all for the hard work on this very nice application!

Comment 7 caulier.gilles 2018-02-14 19:41:26 UTC
Note : since DK > 5.3.0, we left QtMultimedia + GStreamer in favors of QtAV + FFMpeg. This last one is more portable and do not have plenty of run-time dependencies. All codecs are provided de facto...
