I am using Shotwell 0.30.14 "Calle" on Ubuntu 20.04. I have images and videos in my collection. Double-clicking a video is supposed to play it, but it simply doesn't, it just does nothing.
The same videos, and all other videos as well, open happily in VLC from Nautilus.
I guess, if I could configure the path or the app name for the default video player in Shotwell, that would be great, but a lot of searching did not give any useful results.
How can I restore the default video player in Shotwell, or to configure a different one?
