Thank you Alexander for the update regarding progress on JDK-8305842 and the work around advice.
I did a test today using my existing H.264/AVC videos where I triggered the video playing sequence in my application remotely via WiFi every 2 minutes and after 2 hours I had logged many failures to play of individual videos. I re-encoded the 13 relevant videos using Handbrake to H.265/AVEC and repeated the test. To my delight, no errors have been logged and so at least until JDK-8305842 is resolved, I can return to using my application by ensuring any videos are H.265/HEVC and given I have complete control over those videos, that’s not a problem.

Root cause is known, but I did not had time to debug it and fix. If you have ability to convert videos to H.265/HEVC you can use it as a work around for this issue. So far there are no known issues with H.265.

I’m surprised JDK-8305842 has remained unresolved because I assume many others must have encountered this bug. I have certainly had “conversations” with others ( <https://urldefense.com/v3/__https:/www.b4x.com/android/forum/threads/javafx-mediaview-under-win11.166839/__;!!ACWV5N9M2RV99hQ!JCnnNj8uRaA3gfzORTJZ3XJeHlpNthOAggEWddihqaO7nSmnjYB50x9P5gBbOfidm_OBKlKYmA8aQhImHTSkdBiuVfHp1fnd$> https://www.b4x.com/android/forum/threads/javafx-mediaview-under-win11.166839/ & <https://urldefense.com/v3/__https:/www.b4x.com/android/forum/threads/jmediaview.166994/__;!!ACWV5N9M2RV99hQ!JCnnNj8uRaA3gfzORTJZ3XJeHlpNthOAggEWddihqaO7nSmnjYB50x9P5gBbOfidm_OBKlKYmA8aQhImHTSkdBiuVaBWLA89$> https://www.b4x.com/android/forum/threads/jmediaview.166994/) who have also encountered it. In my case since updating from Win10 to Win 11 earlier this year, I have had to abandon using the feature in my basketball stats display application which shows a sequence of short videos because of the random/intermittent/flaky nature of the symptom and reverted to use of a separate application (vMix) to do this, which is disappointing/inconvenient. Incidentally, thank you to this community which I find very welcoming and supportive, especially for someone like me who is somewhat out of their depth.

JDK-8305842 is still reproducible on Windows 11 with JDK-8366217. Thanks, Alexander From: openjfx-dev < <mailto:[email protected]> [email protected]> on behalf of Bryon Dunkley-Smith < <mailto:[email protected]> [email protected]> Date: Tuesday, September 16, 2025 at 6:56 PM To: <mailto:[email protected]> [email protected] < <mailto:[email protected]> [email protected]> Subject: Availability of JavaFX build incorporating JDK-8366217 fix Hi All, Apologies in advance if the terminology in my question is incorrect as I’m somewhat out of my depth here. I have been monitoring <https://bugs.openjdk.org/browse/JDK-8305842> https://bugs.openjdk.org/browse/JDK-8305842 (Video sometimes does not start when reinitializing in Windows 11) for progress with interest because I have a legacy JavaFX based application which has functioned flawlessly for several years, but since upgrading from Win10 to Win1, there has been intermittent/random failures of videos playing with a ERROR_MEDIA_INVALID being thrown, even though I’ve used the same “media” with success previously and it often runs without error. So when I saw <https://bugs.openjdk.org/browse/JDK-8366217> https://bugs.openjdk.org/browse/JDK-8366217 (Update GStreamer to 1.26.5), I wondered if the update to GStreamer may resolve my issue of intermittent/random failures of videos. I see that “This pull request has now been integrated.” and being ignorant of how this finds its way into a release of JavaFX, could someone advise me of how I would know if a version (early release?) is available incorporating this “fix” and where I can download it from. Thanks, Bryon
