Hi @Katalin Chen ,

I don't meet such issue on my Edge (version:117.0.2045.60). On my side, it plays well.

Is it a certain MP4 file that screen blanked, or is it all MP4 files? Can this problem be reproduced on other browsers? Have you ever encountered a similar situation before Edge 117？

You could try to following methods：

1.Clear your browsing data

Settings> Privacy and services> Under the “Clear browsing data” section, click the Choose what to clear button>

Check the boxes Browsing history, Cookies and saved website data and Cached data and files and click on Clear.

2.Disable Hardware Acceleration

Settings> System and performance> disable "Use hardware acceleration when available."

3.Do you have any extension in Edge? You can try to disable all the extensions in Edge and test again.

Then, restart your edge and check if this issue persists.

Best regards,

Wenying Lu

Thanks a lot @Wenying Lu-MSFT , Disable Hardware Acceleration can well solve my problem. But why hardware acceleration causes this result.

Hi @Katalin Chen , Glad to hear that the issue has been resolved！
If the Hardware Acceleration feature is enabled, graphics-intensive tasks will be managed by the GPU, instead of the CPU. While this may help avoid high CPU usage, it may stop Edge from playing videos.

Hi @Wenying Lu-MSFT , thanks for the explanation. Can I ask one more question about mp4 playback? I'm trying to load mp4 via videojs(https://videojs.com/), HTTP authentication is required to access the mp4 file, but I can't attach the headers in the player's options. If I try to add the account and password to the URL to pass HTTP authentication, it also doesn't work, the account and password information doesn't seem to be recognized. I did search something on it.
I found:
(1)Unable to modify headers on media requests #6348
https://github.com/videojs/video.js/issues/6348
(2)How to set headers on native browser requests, or otherwise provide authorization headers while using Video.js to play video from Microsoft Azure?
https://stackoverflow.com/questions/67277533/how-to-set-headers-on-native-browser-requests-or-otherwise-provide-authorizatio
, etc.
Can't figure this issue out now. Do you have any other suggestion on video tools? Or could you tell me is there any solution to add headers on the inner request?

Hi @Katalin Chen , Thanks for the response.

1.Do you have any other suggestion on video tools?

I am a support engineer for the Edge, I don’t know much about videojs.

Also, Microsoft Q&A does not support third-party related issues.

2.Or could you tell me is there any solution to add headers on the inner request?

You can't attach the headers in the player's options, we recommend you open an issue to video.js team.

Thanks for your understanding.
