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/store/productId/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.

    Please provide a link to the HEVC Video Extensions app you downloaded, provider your Windows 10 build, and your full system hardware specifications. Add all this information to the original question by using the EDIT button. Aug 7 '18 at 20:45
  • What makes you think Windows Media Player supports hardware acceleration? I suggest using something other than Windows Media Player to accomplish your task. Reading the description of the HEVC Video Extensions, it does not support Windows Media Player, and never was supposed to. You would have to install a Codec specifically designed for HEVC Video Extensions, but even then, you likely would still have performance issues. There is a good reason Microsoft promotes Movies & TV instead of Windows Media Player on Windows 10

    Strange. I don't have a GoPro but why doesn't their software support files encoded by their own product? reddit.com/r/gopro/comments/8781mm/hevch265_ultimate_faq

    you can create an optimized proxy to work with. The output will be rendered based on the original file

    From what I found, the Quick for Desktop (Windows10) does support the import and playback of HEVC files, but it lacks Hardware acceleration for those HEVC files when you have a Desktop PC with a dedicated graphics card where you cannot switch between integrated and dedicated graphics as you can on a laptop, as often suggested as a solution. Consequently, I think that for hardware acceleration you need to wait for an update to GoPro Quik.

  • I wanted to add: GoPro Quik uses the codec from the store app "HEVC Video Extensions" and it's unknown if the problem is the codec from the store, or if it's the implementation of this codec in GoPro Quik. Dec 21 '18 at 13:18

Microsoft removed free support from Windows 10. To re-enable the HEVC codec they are charging a ransom in their Windows Store: https://www.microsoft.com/store/productId/9NMZLZ57R3T7 .99Dollars At the time of writing it costs 99 cents. enter image description here

A comment below says that this is free. It might have been but it is no longer free.

    Not sure if you did read the question, but they already provides a free version, paid version is not needed for GoPro Quik and doesn't solve the problem as I've tried that: microsoft.com/store/productId/9n4wgh0z6vhq Dec 20 '18 at 13:44
  • Dang, they seem to have removed the free version from being available. Jul 2 at 2:49
