使用OpenJFX 11我正在使用媒体播放器在Linux系统上播放一些片段。其中一些显示，另一些则不显示。据我所知，编码的唯一区别在于，不播放视频包含音轨。这是mediainfo输出的视频的输出：

没有记录或显示错误消息。
如果我没记错，这在以前是有效的，在版本8中使用JavaFX。从那时起我也升级了操作系统，因此它也可能是一些缺少的编解码器。
MediaPlayer播放？Maven项目？我不希望用户需要手动安装其他库，以便我的应用程序工作。[编辑：]关于它与libavcodec有什么关系的可能性是sudo find / -name 'libavcodec*'返回的列表：

事实证明，虽然支持MP3作为音频，但视频不支持它，至少Linux不是开箱即用的。
可以解决的是MP4和AAC用于音频轨道。至少在Linux Mint 18.3上的Java 11，OpenJFX 11中也是如此。
