Using OpenJFX 11 I am using a mediaplayer to play some clips on a Linux system. Some of them display, others don't. As far as I can tell the only difference in the encoding is, that the not playing video contains an audio track.
This is the output of mediainfo for the video that plays:

There is no error message logged or displayed.
If I remember correctly this has worked before, when using JavaFX in version 8. Since then I also upgraded the OS, so it could be some missing codecs as well.
MediaPlayer?Maven project? I do not want the user to require to install additional libraries by hand, so that my application works.[EDIT:]
On the chance that it has anything to do with libavcodec here is the list returned by sudo find / -name 'libavcodec*':

Turns out that while MP3 is supported as audio, it is not supported for video, at least not out of the box for Linux.
What works through is MP4 together with AAC for the audio track. At least this is true for Java 11, OpenJFX 11 on Linux Mint 18.3.
