我需要一个内部.wav(在源文件夹中(才能加载到媒体播放器中而不会出错。
我昨天让它工作了，并提交了它工作的代码。今天，回滚到该提交显示以下错误：

Exception running application Main
我想强调的是，昨天同样的代码运行良好。
我发现这个问题，但它似乎已经过时了。无论如何，我在Arch上安装了最新版本的ffmpeg。
我也发现了这个堆栈溢出的帖子，但由于它早些时候起作用，我相信我引用的文件是正确的。
以防万一，这里是文件结构：
main
- java
- Engine.java
- resources
- audio.wav
以及创建播放器的代码：
Media music = new Media(getClass().getResource("/audio.wav").toURI().toString());
player = new MediaPlayer(music);
根据ArchWiki，该异常可能是由于某些不兼容而引发的。
工作解决方案是安装ffmpeg-compat-55AUR包。
