I've noticed that Ubuntu 16.04 running KDE's Dolphin file manager is not able to preview audio thumbnails for some reason. I'm not certain why, and I've checked the Configure Dolphin -> General -> Previews -> File Types, and Audio is not listed as a supported type (It doesn't appear at all) Is there some way I can fix this? I interact with audio and am religious about tagging them with pictures and it kind of sucks not being able to see the thumbnails.

Note: I've seen https://www.linux-apps.com/content/show.php?content=114885, but a lot of people were saying that it didn't work, and it doesn't appear to be the same version of KDE that I'm running.

Edit 0: After following the cmake instructions, I got this error wen trying to run make: make command


KDE preview thumbnail

The KDE applications can show a thumbnail for a file if there is a thumb creator plugin installed for the file type. After installation the plugin need to be enabled from the application settings.

Current KDE is released as three projects: Frameworks, Plasma and KDE Application. Release schedules: https://community.kde.org/Schedules

Application and the Framework version can be looked at the application help. With the Dolphin: Dolphin > Control > Help > About Dolphin:

  • Maybe I'm not well versed, but I can't figure out what to do after I download the zip from github. There are uncompiled C files there and the Readme is rather vague. As far as instructions, what should I do? Is there a PPA I can add? Should I compile and run the C file from the github repository? – Sarah Szabo May 25 '17 at 2:50
  • Did you read the compilation example ? Installed the needed files ? Tried the commands ? – user26687 May 25 '17 at 8:48

    I got an error after running the make command. `cmake went just fine though. – Sarah Szabo Jul 4 '17 at 0:44
  • Your error message has: 'fatal error: QObject: No such file or directory'. Do you have the package : qtbase5-dev installed ? – user26687 Aug 13 '17 at 19:10
  • The package is updated with taglib1.11 dependency, which is not in ubuntu 16.04. compiling taglib didn't help – Anwar Feb 11 '19 at 20:27
