Hi, running shotwell shipped with Fedora 40 there are no thumbnails for mp4 videos after import.

shotwell.log:

/app/libexec/… indicates that you are using Shotwell from a flatpak. If this is the flatpak from flathub, it only contains the OpenH.264 codec which seems to have issues with a variety of files, like unsupported profile versions.

I was just running shotwell via gnome shell.

I’ve never used flatpack.

But you are right. This funny fedora software app indeed installed shotwell as flatpak :slight_smile: thank’s a lot!
