4k HEVC Decode in Linux - App Adjustment Needed? - Krobar - 2015-09-19
Hi All,
I noticed the rest of the chain for VDPAU HEVC decode was marked stable in last month or so:
NVidia Driver support has fixed most of the bugs 2 releases ago (Including what held back FFMPEG)
libvdpau support is good in V1.2+
FFMPEG support is no longer marked as experimental
Are any app changes needed? Is Kodi 16 likely to support 4K HEVC decode?
RE: 4k HEVC Decode in Linux - App Adjustment Needed? - wsnipex - 2015-09-19
it already does
RE: 4k HEVC Decode in Linux - App Adjustment Needed? - Krobar - 2015-09-19
Just Installed Kodi 16 Alpha 3 along with Libvdpau 1.1.1 and the Nvidia 355.12 driver. Doesn't seem to be any hardware HEVC decode support though (Using an Nvidia Geforce 960). Do I need to do something else to enable the support? Or is the Ubunutu package not built with a new enough version of FFMPEG?
RE: 4k HEVC Decode in Linux - App Adjustment Needed? - wsnipex - 2015-09-20
make sure your libvdpau has hevc support. IIRC 1.1.1 is not enough

I cant find a version newer than 1.1.1 here: http://people.freedesktop.org/~aplattner/vdpau/?C=M;O=A.
Also tried the nightly build (20/09/15) and it also does not seem to accelerate HEVC either, Kodi does detect HEVC but then seems to send it to the cpu, I get about 3fps on the 2 2.0Ghz Opteron cores within my VM.

Is there something I'm missing which is not yet merged?

Debug Log please
and moving to linux support

No all is fine. Was reported working by PhillipI that did the ffmpeg work. Your Debug Log will tell us.

Thanks for the replies, here is my log:

Retry and don't cut the important parts.
Btw. As you are at it, your 24.0 and your 23.976 hz mode is totally wrong. Nvidia needs an xorg.conf to get those correct. But that has nothing to do with HEVC.

Here is the entire log file:

btw. you run this in a virtual machine?

Does VDPAU work for h264? For completeness also post a mediainfo of this file ...
RE: 4k HEVC Decode in Linux - App Adjustment Needed? - Krobar - 2015-09-20
Hi,
Yes, run it in a KVM VM with VFIO passthrough of the video card. H264 acceleration definitely works, I get 15-20% across both cores with a 40mbit file when vdpau is enabled. If I disable vdpau then CPU climbs to 70-100% with severe drops in frame rate.
Mediainfo for the 3 sample files I have tried:

Post a log with you playing h264 - for now I see no indication of any vdpau actually working in your logs.
Here is a 4k hevc file that works on my system: http://www.libde265.org/hevc-bitstreams/bbb-3840x2160-cfg02.mkv

Here is a log of H264 With and Without VDPAU:

Thanks for the Link, will give the file a try tomorrow.
