Hello everyone,
I am working on a custom theme for SDDM that can play videos in the background. The theme works perfectly when I test it using:
sddm-greeter --test-mode --theme .
However, when I try to use it in the actual login screen, it fails to play the video. After several hours of debugging, I am confident the issue is related to missing GStreamer plugins, which seem to be unavailable during the login session.
Here’s the relevant journalctl log:
Oct 11 23:50:57 MDario sddm-greeter[1195]: Error: " filesrc location=/nix/store/xcslir9jw3plr071j0ish1xbc506pvxz-video.mp4 ! decodebin ! autovideosink" : "no element \"decodebin\""
Does anyone know how I can ensure that the required GStreamer plugins are available to SDDM during login on NixOS?
For reference, the theme I am working on is here: sddm-glacier.
Thanks in advance for any help or suggestions!
