Hi I am trying to enable hardware decoding for H265/HEVC in Kodi 15, I have already clicked the button in the settings that is supposed to enable VDPAU. However it is still using ~100% of all 6 of my CPU cores, causing periodic and massive decoding errors.
I am sure my GPU supports this as I can force Hardware decoding using VLC/ffmpeg causing it to only keep one core under load and the GPU at ~15%.

Here is a link to my kodi.log https://paste.ubuntu.com/26412043/

Assistance in this would be greatly appreciated.

Nvidia has no h265 10 bit support in Linux via vdpau at all.

H265 8 bit vdpau is not supported in v15.

hardware decoding for H265/HEVC in Kodi 15

I think you first need to properly install Kodi 17.6, using the PPA repos mention in Kodi's installation wiki page. Kodi 15 is prehistoric by now.

And yes, Nvidia in Ubuntu Linux only supports 8-bit video.

Thank you, getting the lastest version from the ppa did solve the hardware decoding issue.

And I assume you're already aware but I did get the other version via apt-get in Ubuntu 16.04, so it might be worth looking at pushing out a later version to that.

I am using GT730 / KODI 17.6 with nvidia-390 on Ubuntu 14.04 but still cannot get hardware decoding for 8-bit H265/HEVC working...

Hi samsonluk,

I cannot help you get Hardware decoding in kodi working, as I haven't figured it out, and moved onto other options.

However I can tell you that your GPU doesn't actually support hardware decoding for HEVC/H265.
Figuring this out is difficult and confusing since Nvidia basically keeps this information under lock and key.
You need a GPU which supports Purevideo/VDPAU Feature set F or later (G, H, I, etc) (https://en.wikipedia.org/wiki/Nvidia_Pur...ature_Sets)
And you can find a list of GPUs that have the different versions of the Purevideo hardware in this table
(https://en.wikipedia.org/wiki/Nvidia_Pur..._SIP_block)

So looking at the table I linked, you would need a GeForce GTX 750 SE, GTX 950, GTX 1050, GT 1030 minimum.

I hope that helps.
