This seems to be a recurring issue:

After updating from Linux Mint 18 to Linux Mint 20, the creation of MediaPlayer for this file fails (the locator uri is on the same file system) due to ERROR_MEDIA_AUDIO_FORMAT_UNSUPPORTED. Loading a *.wav file works though and from that I get this debug output:

Debug (0:00:05:544): Creating AudioClip for URI file:/home/.../target/classes/sound/organ.wav
Debug (0:00:05:591): Enabled JFXMedia platforms: 
   - com.sun.media.jfxmediaimpl.platform.java.JavaPlatform
   - com.sun.media.jfxmediaimpl.platform.gstreamer.GSTPlatform
Debug (0:00:05:591): JFXMedia supported protocols:

    https

Debug (0:00:05:594): Getting content types from platform: com.sun.media.jfxmediaimpl.platform.gstreamer.GSTPlatform@3e10dcb9
Debug (0:00:05:594): JFXMedia supported content types:
    audio/x-aiff
    audio/mp3
    audio/mpeg
    audio/x-wav
    video/mp4
    audio/x-m4a
    video/x-m4v
    application/vnd.apple.mpegurl
    audio/mpegurl

The protocol here is file and the mime type is audio/mpeg which are both in the supported list above. Obviously the platform that is used is GSTPlatform.

As I understand it this is a problem with a missing codec. However I made sure that these libraries are present:

  • libavutil56
  • libavformat58
  • libavcodec58
  1. Did I miss a library that is required?
  2. Is there a way to have an additional Platform that would work?
  3. What needs to be done to change the content type to be recognized as audio/mp3 instead of audio/mpeg and would that possibly solve the issue.

As mentioned above the same code could initialize the player with this file on Linux Mint 18, so it cannot be an issue with the code itself, but must be in the environment.
