[SOLVED] Thumbnail preview of videos with H.265 codec

[Gabarito]

I installed Windows 11 on a new computer.
Soon after, I installed Everything 1.5.0.1396a.

I needed to find a video and used the thumbnail preview option.

In the old Windows 7, they displayed correctly.
But now, only the MKV video logo appears.

These videos are encoded in H.265.
MP4 videos, in H.264, are displayed correctly.

How can I view MKV videos in H.265 as well?

Thanks.

Are these thumbnails missing in File Explorer too?

Maybe this helps?

No thumbnails for video files

Installing a 3rd party video thumbnail handler (like Icaros) should solve the issue too.

Windows Explorer was also only displaying the "mkv" logo.

Installing Icaros solved the problem.
Thank you for the suggestion.

Solved.
