Can’t get Dolphin play videos.
Got installed:
What else do I need? How can I fix it?
You have the right package which is ffmpegthumbnailer.
Can’t remember if you need to go into dolphin settings and put a tick in the ‘enable video thumbnails’ box. Post back if you need a ‘step-by-step’ guide to do this.
Steps are:
open dolphin
control tab (at top)
2nd to bottom option - configure dolphin
general / previews tab
put a tick in ‘video files (ffmpegthumbs)’
It’s already enabled.
