Wayland: Video won't play. Unable to create player: gtkglsink is missing.

[dasgarner]

On Ubuntu 22.04 under Wayland, either via vscode or snap any layouts which have video do not play, and the following error is logged.

[19:26:43.080] [151560] [error]: [LayoutsManager] [LayoutParser - RegionParser - MediaParser - GstMediaPlayer] Layout 1560 is invalid or missing. Reason: Unable to create player: gtkglsink is missing.

I thought this might be because libgstreamer-plugins-good1.0-0 is missing from the devcontainer, but adding that didn't fix the issue.

The previously working snap build also suffers with this issue, so perhaps something external to us has changed.

@dasgarner please, recheck this issue on edge channel version

I now get the below, but videos do play! I think we can consider this solved in edge-240.

** (xibo-player:35446): WARNING **: 08:02:25.534: Accelerated compositing is not supported under Wayland displays, disabling.

Apologies, I spoke too soon - when a video finishes playing I get the following error:
