[Problem/Bug]: Black Screen on video with DRM using keysystem Hardware or recommendation.3000

[slherm]

What happened?

Hi Team,

we are using WebView2 on our streaming app for UWP device (myCANAL french app on windows & xbox).

We use an open source eme/mse player (rx-player) and recently some of our customer have a black screen issue on all videos (but sound is OK).
It's only a part of windows 11 OS (everything is ok on windows 10) and only if we try to use keysystems playready.hardware or playready.recommendation with SL3000
If we switch to playready.software everything is fine but we prefere to use SL3000 keystems to deliver the best quality to our customers.
We have identified a configutation with this issue :

• Windows 11 Version 24H2 pour les systèmes x64 (KB5046617)
  
  

Thank a lot for your help & support

Thanks for reporting the issue. Can you kindly provide following info:

1. Was this scenario working earlier? If so, can you kindly share till which version of runtime this was working.
2. Is there a reduced sample where the issue can be repro-ed?
3. Can you confirm if this is not a remote playback - screen sharing or remote desktop?
4. Does the monitor/connection support HDCP 2.2?

Thanks for providing the logs @slherm . May I also request you to validate if the issue repros with Win32 Sample app and UWP Sample App when you navigate to the site in the sample app?

diffucult to do this because we do not reproduce on our development computer. not easy to ask people to install visual studio...
