Kodi + GTX 1080 + 4K hevc decode - 03397 - 2016-12-23

I am using Kodi 16.1 on a windows 7 machine and recently I have installed an asus GTX 1080 video card which supports hardware decoding of hevc 4k.
I am tryting to play an mkv file 4k hevc but instead of using the video card to decode it is using software.

Can someone help me with this?
Is this supported in Kodi 16.1? Do I need to install any codecs?

try the Kodi 17 beta 7. i think it has to work.

You are unable to select DXVA rendering? Then there is an off/on option to allow hardware acceleration.

It did not work. I have upgraded to kodi 17. It still uses software decode.

The hardware accelaration was set up to auto. I changed it but I am getting the same thing

Did you try going into Nvidia Control Panel and selecting GTX 1080 PhysX setting instead of CPU or Auto?

What does PhysX have to do with anything?


RE: Kodi + GTX 1080 + 4K hevc decode - afedchin - 2016-12-27

Windows 7 doesn't support 10-bit textures which is required for hevc main10 decoding. This is limitation of windows 7 version of DirectX 11.1

Doesn't it take decoding calculations off the CPU (software) and route them to the GPU (hardware)?


RE: Kodi + GTX 1080 + 4K hevc decode - afedchin - 2016-12-27

PhysX does nothing for Kodi.

So I should upgrade to Windows 10?


RE: Kodi + GTX 1080 + 4K hevc decode - wsnipex - 2017-01-04

yes


RE: Kodi + GTX 1080 + 4K hevc decode - afedchin - 2017-01-04
