Using OpenJFX 11我正在使用媒体播放器在 Linux 系统上播放一些剪辑。其中一些显示，另一些则不显示。据我所知，编码的唯一区别是，未播放的视频包含音轨。
这是的输出mediainfo对于播放的视频：

没有记录或显示错误消息。
如果我没记错的话，以前在版本 8 中使用 JavaFX 时，这曾经有效过。从那时起，我还升级了操作系统，因此也可能缺少一些编解码器。
- 我如何对视频进行声音编码，以便使用 JavaFX 播放
MediaPlayer?
- 如果在某些操作系统上需要提供额外的编解码器，如所示这篇旧文章 https://docs.oracle.com/javase/8/javafx/media-tutorial/overview.htm#JFXMD101，如何做到这一点
Maven项目？我不希望用户要求手动安装额外的库，以便我的应用程序正常运行。
