there are some quirks on HDMI 2.0 but they arnt that bad and their seems to be pretty complete support with the amdgpu-pro drivers

am using a Samsung UE55HU7505 55" 4K television using HDMI 2.0, you might not need amdgpu-pro but for my television i needed the pro drivers

  • You must use Ubuntu 16.04 LTS or Linux 4.4 (i used xubuntu)
  • You must use AMDGPU-PRO Drivers! (if you using HDMI 2.0 4K television)
  • 4K AVC works fine
  • 4k HEVC Main works fine
  • 4k HEVC Main10 (vpau nope, not implemented currently in libvdpau?)
  • 4k HEVC Main10 (vaapi works with mpv, we lose quality due to outdated surfaces and stuff but will play in hardware)
  • also HEVC Main10 migh work in kodi 16 using older render engine
  • Rant: wtf is it with DPI and Linux? its stupidly small by default :/
  • You can ignore DISPLAY=:0 if you are not using ssh in this guide
  • FYI: all those screenshots are in all their 4k glory if you right click and open image in new tab

But first we need to some background music for our work

Install amdgpu-pro, mpv & Kodi

First we install the latest beta/rc builds of kodi/mpv and the amd-gpu-pro driver ofc

  • sudo add-apt-repository ppa:team-xbmc/unstable -y
  • sudo add-apt-repository ppa:mc3man/mpv-tests -y
  • sudo apt-get update && sudo apt-get upgrade
  • sudo apt-get install vdpauinfo p7zip-full ppa-purge
  • wget --referer="http://support.amd.com/en-us/kb-articles/Pages/AMDGPU-PRO-Install.aspx" https://www2.ati.com/drivers/linux/ubuntu/amdgpu-pro-16.50-362463.tar.xz
  • 7z x amdgpu-pro-16.50-362463.tar.xz && 7z x amdgpu-pro-16.50-362463.tar
  • chmod +x amdgpu-pro-16.50-362463/amdgpu-pro-install
  • sudo amdgpu-pro-16.50-362463/amdgpu-pro-install

Fixing vdpau & vaapi

  • sudo mkdir -p /usr/lib/x86_64-linux-gnu/vdpau/
  • sudo mkdir -p /usr/lib/i386-linux-gnu/vdpau/
  • sudo ln -s /opt/amdgpu-pro/lib/x86_64-linux-gnu/vdpau/libvdpau_amdgpu.so.* /usr/lib/x86_64-linux-gnu/vdpau/
  • sudo ln -s /opt/amdgpu-pro/lib/i386-linux-gnu/vdpau/libvdpau_amdgpu.so.* /usr/lib/i386-linux-gnu/vdpau/
  • sudo ln -s /opt/amdgpu-pro/lib/x86_64-linux-gnu/dri/radeonsi_drv_video.so /usr/lib/x86_64-linux-gnu/dri/amdgpu_drv_video.so

Fixing Tearing

  • sudo nano /usr/share/X11/xorg.conf.d/10-amdgpu-pro.conf
Section "OutputClass"  
        Identifier "amdgpu-pro"
        MatchDriver "amdgpu"
        Driver "amdgpu"
EndSection

Section "Files"  
        ModulePath "/opt/amdgpu-pro/lib/xorg/modules"
        ModulePath "/usr/lib/xorg/modules"
EndSection

Section "Device"  
Identifier  "Card0"  
Driver      "amdgpu"  
BusID       "PCI:1:0:0"  
Option      "DRI3" "1"  
Option "TearFree" "on"  
EndSection  

Kodi 17

adding amdgpu temperature to kodi

nano $HOME/.kodi/userdata/advancedsettings.xml

<advancedsettings>  
<gputempcommand>sensors amdgpu-pci-0100 | sed -ne "s/temp1: \+[-+]\([0-9]\+\).*/\1 C/p"</gputempcommand>  
</advancedsettings>  

Use mpv for HEVC Main10 Content (seem to work but we lose quality due to outdated surfaces and stuff but it will play in hardware on a underpowered system)

nano $HOME/.kodi/userdata/playercorefactory.xml

<playercorefactory>  
 <players>
   <player name="mpv" type="ExternalPlayer" audio="false" video="true">
     <filename>mpv</filename>
     <args>--hwdec=vaapi --fs</args>
     <hidexbmc>false</hidexbmc>
     <hideconsole>false</hideconsole>
     <warpcursor>none</warpcursor>
   </player>
 </players>
 <rules action="prepend">
   <rule filetypes="mkv|mp4" filename=".*hevc.*" player="mpv"/>
 </rules>
</playercorefactory>  

now we need to add kodi to autostart
Xfce Menu -> Settings (-> Xfce 4 Settings Manager) -> Session and Startup -> Application Autostart tab

Uninstall

  • ./amdgpu-pro-install -u (Uninstall amdgpu-pro)
  • ppa-purge team-xbmc/unstable (remove kodi betas)
  • ppa-purge mc3man/mpv-tests (remove mpv betas
