Same problem, have you fixed it?

Ubuntu 22.04, GMONE 42.9

Same here Ubuntu 22.04, GMONE 42.9

Same here Pop!_OS 22.04, GNOME 42.5

This seems a codecs issue, please make sure that the multimedia codecs for GStreamer has installed in your system. Generally, WebM format has a better OOTB experience, as it's an open format and many distro ship the codec by default.

Just FYI, we have dedicated installation guides for both Ubuntu and PopOS. If you haven't read it, please take a look, the links are available in the README page. 😉

I reinstalled everything following the dedicated installation guide and I still experience the same issue.
With MP4 and webM format.
Thanks for your help

Same issue. I tried to apply video as wallpaper, and I get black background. Is there solution to this problem?

I have the same exact problem in Pop!_OS 22.04 with gnome-shell 42.9, the video does play but distorted this way. I was using .mp4 files downloaded from wallpaper engine, but they play nicely in VLC so i don't think that is the problem.
