Mpvpaper Drops All Frames, Only Black Output (NixOS/Hyprland)

[natervader]

mpvpaper consistently loads a black output regardless of the file I choose or whatever other options I test.

System info:

• AMD Ryzen 9 3900X
• NVIDIA RTX 3060
• NixOS
• Hyprland (with NVIDIA patches)
• Two displays, ViewSonic XG2701 and a Dell 1708FP

Output of mpvpaper '*' loop.mp4 -vv:

[*] Exiting mpvpaper

Not sure what else can be mentioned from my end on the issue. I realize this can be an issue with how NixOS handles the NVIDIA drivers or simply NVIDIA's shoddy Wayland support but figured I'd report it regardless.

Let me know if there's anything else I can add to assist in debugging!

By the look of your verbose logs and by looking up the mpvpaper package in NixOS. You are running a very old version of 1.3 mpvpaper!! https://search.nixos.org/packages?channel=23.11&show=mpvpaper&from=0&size=50&sort=relevance&type=packages&query=mpvpaper

This issue was just recently fixed in version 1.6 So either compile the package from master or get someone to update the Nix package.

I seems that it's up to date in the "unstable" repo try that: https://search.nixos.org/packages?channel=unstable&from=0&size=50&sort=relevance&type=packages&query=mpvpaper

That did the trick! No kidding, never thought to check if the stable branch was that out of date. Thanks a bunch @GhostNaN.
