GeometryWars fails to load bgm.mp3: "jfxmedia.MediaException: Could not create player"

I spotted http://almasb.github.io/FXGLGames/ on reddit, and tried out the first example listed: GeometryWars. I cloned FXGLGames, changed directory to GeometryWars, executed mvn package which succeeded, and ran the jar with java -jar and it failed. See log output, etc: http://hastebin.com/fuvuholatu.sm

After a long search through libraries and dependencies I’ve managed to install libavcodec and libavformat on a clean fedora 24. In short, ../jre/lib/amd64/ has libavplugin(53-56).so, so basically ffmpeg-compat gives version 52, which is no longer supported in jdk8_102, the new ffmpeg gives 57, which is not yet supported. So best bet is to use 56.

The rpm I used is here.

dnf install DOWNLOADED_RPM.rpm will say that a few .rpm are missing, so they have to be downloaded again manually using the same repo. Here’s a shortcut for x86_64.

Once ffmpeg installs, you will find several libav*.so in /usr/lib64/ffmpeg-full-libs/ or wherever it installed them. All of the libav*.so need to be copied to /lib64/.

This should do it, though I installed a few other things along the way like gstreamer* and glib*, so not entirely sure at what point the game stopped throwing the exception
