JavaFX MediaView Problem After Win10 to Win11 Update

[Bryon Dunkley-Smith]

Thank you Kevin.

 

I’ve tried using a recent build of JavaFX 25 ea, build 18 I believe and the symptom of “flaky” display of videos remains.

 

Hopefully evaluation of https://bugs.openjdk.org/browse/JDK-8305842 will confirm the bug and a solution will eventuate. In the meantime, I’ll use a Win10 machine!

 

Thanks,

 

Bryon

Another possibly related bug is https://bugs.openjdk.org/browse/JDK-8329227 which is fixed in JavaFX 25 ea build 14. You might try running with the latest JavaFX 25 build and see if that helps.

If not, then it does seem likely that you are hitting https://bugs.openjdk.org/browse/JDK-8305842 which is being evaluated.

Hi All,

 

First time poster and so I trust this is an appropriate question to ask here.

 

I have a legacy JavaFX based application which in part displays a sequence of short (.MP4) videos which has functioned flawlessly for several years as demonstrated here https://www.youtube.com/watch?v=CMv6z_SIUXU. But since upgrading the laptop on which it runs from Win10 to Win11 some months ago, there has been intermittent/random failures of videos playing with a ERROR_MEDIA_INVALID being thrown. I have tried many code changes to fix this unsuccessfully however a common “fix” across several machines is always just running it on a Win10 machine.

 

I note there is an unresolved bug report Video sometimes does not start when reinitializing in Windows 11 https://bugs.openjdk.org/browse/JDK-8305842 which appears relevant.

 

So I am wondering if others have encountered this problem and whether there is a plan to resolve this bug in an upcoming JavaFX release.

 

Thanks,

 

Bryon
