ADDITIONAL SYSTEM INFORMATION :
Windows 10, 64 bit, jre 1.8.191 (all versions of java)

A DESCRIPTION OF THE PROBLEM :
The MP4 is 1080 x 1920, portrait instead of landscape. It will not play in oracle, nor Azul JavaFX media player. What can you do for us to help us out?

This may not be a critical bug to some people, but it is to CSG now, because we cannot play video on our new kiosks. Here are a few tickets I’ve found that have been open for years they have not addressed:
https://bugs.openjdk.java.net/browse/JDK-8133841
https://bugs.openjdk.java.net/browse/JDK-8091277

ERROR:
MediaException: UNKNOWN : [com.sun.media.jfxmediaimpl.platform.gstreamer.GSTMediaPlayer@21ec8c7f] ERROR_MEDIA_INVALID: ERROR_MEDIA_INVALID

at com.sun.media.jfxmediaimpl.NativeMediaPlayer$EventQueueThread.run(NativeMediaPlayer.java:426)


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Simply play a 1080x1920 video in portrait mode in java fx media player.

run the java class below, put a video 1024x1980 in the same directory named largevideo.mp4.

Email me if you need the largevideo.mp4 and i can send it.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Video would play, but it does not
ACTUAL -
Video will not play
