Bounty: 50

Playing HEVC H.265 videos using Windows Media Player and GoPro Quik then the 4k 60 fps video appears all stuttering and becomes a slideshow. The CPU usage is going through the roof and it’s not using Hardware Acceleration. I have installed the “HEVC Video Extensions” from Microsoft Store. When I use the app “Movies & TV” for playing the video file then it uses around 1% CPU and Hardware Acceleration seems to be enabled.

How can I get Windows Media Player and GoPro Quik to use Hardware Acceleration?

“HEVC Video Extensions from Device Manufacturer” (Free version that works with licence software like GoPro Quik): https://www.microsoft.com/en-us/store/p/hevc-video-extension/9n4wgh0z6vhq

I have tried following:

  1. Uninstall all codecs, also the “HEVC Video Extensions” from Store: Windows Media Player plays only the sound, screen is black. Unable to open video in GoPro Quik
  2. Installed K-Lite Codec Pack (w/HEVC codec): Windows Media Player plays the video with both video and audio smoothly. The playback is hardware accelerated as it only used 1% CPU. Unable to open video in GoPro Quik
  3. Install “HEVC Video Extensions” from store (Regardless if K-Lite is installed or not): Windows Media Player plays video with both video and audio but it’s stuttering. Playback is not hardware accelerated and it uses near 100% CPU. GoPro Quik is now able to open and edit the video but it’s stuttering, using 100% CPU on playback and hard to edit the movie

System specifications:

  • Windows 10 Pro N, Version 1803, OS Build 17134.165
  • Intel i7-8700K @ 3.7Ghz (8th gen, coffee lake, newer then Kaby Lake)
  • 16 GB Ram
  • Nvidia GeForce 1070 GTX (Driver version 398.82 which is the newest)

One solution would be using software like Handbrake to convert the video file from H.265 to H.264, but I consider that a “hack” as this really should work with my system spec.
