FXGLAssetLoaderService "Failed to load" mp3; MediaException: Could not create player

[travisfw]

Hi, I'm just trying to get started with FXGL. I've done JavaFX work, but it's been some years, and this is my first attempt to use FXGL, so I could easily be missing something obvious. I can't seem to get around this error with the bgm.mp3 file. It's on disk, and it plays (with open build/resources/main/assets/music/bgm.mp3), but…

This issue shows up on SO without (again, unless I'm missing something) a solution except for "don't use the mp3 format."

Hi, I was going to try and guess what the issue could be, but then remembered there was another project with the same issue: FXGLGames and a possible workaround.

The issue itself stems from javafx not being able to find the required libs for playing the media.

Wow, that was me 😳 oops. Thanks.
