Windows 10: My PC won't generate thumbnails for HEVC videos anymore

My PC previously would generate thumbnails for HEVC 265 videos. It suddenly stopped I don't know why. I cleared the thumbnail cache and now HEVC 265 videos that had thumbnails before won't regenerate them. 264 videos and photos generate thumbnails just fine. It is just HEVC 265 videos that will not make thumbnails.

Windows File Explorer does not generate thumbnails for HEVC videos any more

In the beginning of December 2018, I started to record video-clips with HEVC/H.265 codec. I realized immediately that there was no build-in support in Windows 10 for this codec. I found and installed the app “HEVC Video Extensions
from Device Manufacturers” from Microsoft Store and everything worked fine. The HEVC video-clips was correctly displayed with thumbnails in the File Explorer. I could view video-clips with the Film and Photo apps.

Just a few days ago I bought and installed the app "HEVC Video Extension" from Microsoft Store. This was a big mistake. The File Explorer does not generate thumbnails anymore, when I store new HEVC files in a folder. For the
old files the thumbnails are shown. I guess that Microsoft has altered something in the interface from the first HEVC app to the next one. And File Explorer has not been update. Look at the picture, two mp4/HEVC clips. The left file is stored after the update
and the right before.





Has anybody else noticed this problem_

 

x265 HEVC Video not playing or thumbnails

Hi,
My desktop PC (64bit Windows10 home) will not play HEVC videos with the default player, I just get a blank screen but can hear the audio. When viewing the files folder I just get the program icon and not a thumbnail. I assumed HEVC was not supported but trying the same files on another Windows10 laptop and they work fine.

How do I fix this?

Thanks

JD

 

x265 HEVC Video not playing or thumbnails

Do the two devices have the same video card? That could explain why one plays the HEVC file and the other does not.
