[Interest] QMediaPlayer fails to reproduce videos with codec HEVC - Qt 6.6.3 - Windows 10

Hi,

I’m having a problem that I can’t find a pattern. 

I can’t open videos with HEVC codec on Windows 10 machines with K-Lite Code Basic pack.

But, it plays correctly on Windows 11. However, some users say that they are on Windows 11.

The error is “Unsupported media, a codec is missing”

This didn’t happen with Qt 5.15.9. 

I believe this could be related with the new multimedia backend.

Has anyone had a similar problem?

Any ideas?

Thanks in advance!

Best regards,

Nuno
