Hello, As I found on a coment here:
https://bugzilla.redhat.com/show_bug.cgi?id=1169047#c3 You can work around it by using ffmpegthumbnailer like this: 1.- move or backup /usr/libexec/shotwell/shotwell-video-thumbnailer 2.- Install ffmpegthumbnailer 3.- Create a new executable file /usr/libexec/shotwell/shotwell-video-thumbnailer 4.- Put this inside: #!/bin/bash ffmpegthumbnailer -i "$1" -o - -c png It works fine for me now. Actually I get better thumbs because even when it was working, shotwell-video-thumbnailer often generated green thumbs that were not very useful. Regards, Teo. -- Teo Romera teorom...@gmail.com
