javafx crashes in loop because of gstreamer state change error

[M!X]

configuration: ubuntu, jdk15, javafx11, language level: java 8 

code example(I'm using it to simply my scenario, the error can always happen when it loop after around 100 times):

the origin error:

I tried to debug it, and find the original error msg is: com.sun.media.jfxmedia.MediaError:ERROR_GSTREAMER_PIPELINE_STATE_CHANGE

it is from a native method, i don't know what happens in it.

the throwed out exception msg:

Caused by: MediaException: UNKNOWN : com.sun.media.jfxmedia.MediaException: Could not create player! : com.sun.media.jfxmedia.MediaException: Could not create player! at javafx.media/javafx.scene.media.MediaException.exceptionToMediaException(MediaException.java:146) at javafx.media/javafx.scene.media.MediaPlayer.init(MediaPlayer.java:518) at javafx.media/javafx.scene.media.MediaPlayer.<init>(MediaPlayer.java:421) at org.openjfx/org.openjfx.App.main(App.java:35) ... 11 more Caused by: com.sun.media.jfxmedia.MediaException: Could not create player! at javafx.media/com.sun.media.jfxmediaimpl.NativeMediaManager.getPlayer(NativeMediaManager.java:295) at javafx.media/com.sun.media.jfxmedia.MediaManager.getPlayer(MediaManager.java:118) at javafx.media/javafx.scene.media.MediaPlayer.init(MediaPlayer.java:474) ... 13 more Exception running application org.openjfx.App

Sorry, nothing to do with us. JavaFX has its own, very minimal,
GStreamer integration (they call it GStreamer-lite). You'll need to
take it up with them - https://github.com/openjdk/jfx

Best wishes,
