KODI INSTALL

Main instructions from here

Base OS install of Ubuntu server 20.04.1 64bit

1. install no additional packages apart from ssh.
2. Do not use encrypted home directory.
3. don't partition with lvm, just full disk guided
4. you can setup a default user 'kodi' with whatever password or setup your own user and add the kodi user later

sudo sysctl -p

Remove the Ubuntu MOTD text on login and it's auto update

sed -i "s/ENABLED=1/ENABLED=0/" /etc/default/motd-news # run as root
sudo systemctl disable motd-news
sudo systemctl disable motd-news.timer

apt-get remove --purge landscape-common
sudo chmod -R 0644 /etc/update-motd.d/
sudo vi /etc/default/motd-news
#set enabled=0
sudo vi /etc/pam.d/login
sudo vi /etc/pam.d/sshd
#comment out these lines:
#session    optional    pam_motd.so motd=/run/motd.dynamic
#session    optional    pam_motd.so noupdate


# extreme version doesn't even show last login info
#sudo touch ~/.hushlogin

Allow “everyone” to start the x server

sudo dpkg-reconfigure xserver-xorg-legacy

Now edit /etc/X11/Xwrapper.config and add the following into a new line at the end of the file:

needs_root_rights=yes

Create the kodi user and it add it the relevant groups. If you have created the kodi user during installation only do the usermod part.

sudo adduser kodi
sudo usermod -a -G cdrom,audio,video,plugdev,users,dialout,dip,input kodi

Permission to shutdown, suspend the computer, therefore create the file /etc/polkit-1/localauthority/50-local.d/custom-actions.pkla with the following content:

[Actions for kodi user]
Identity=unix-user:kodi
Action=org.freedesktop.login1.*;org.freedesktop.udisks2.*
ResultAny=yes
ResultInactive=yes
ResultActive=yes

[Untrusted Upgrade]
Identity=unix-user:kodi
Action=org.debian.apt.upgrade-packages;org.debian.apt.update-cache
ResultAny=yes
ResultInactive=yes
ResultActive=yes

We need a simple systemd service file (this one actively waits on network connection, see: network-online.target remove that if you don't need to wait)
Create the following file and put the listing into it: /etc/systemd/system/kodi.service

[Unit]
Description = kodi-standalone using xinit
Requires = dbus.service
After = systemd-user-sessions.service sound.target network-online.target mysql.service
Wants = mysql.service

[Service]
User = kodi
Group = kodi
Type = simple
PAMName=login
ExecStart = /usr/bin/xinit /usr/bin/dbus-launch --exit-with-session /usr/bin/kodi-standalone -- :0 -nolisten tcp vt7
Restart = always
RestartSec = 5
#ExecStart = /usr/bin/xinit /usr/bin/dbus-launch --exit-with-session /usr/bin/openbox-session -- :0 -nolisten tcp vt7
#Restart = on-abort

[Install]
WantedBy = multi-user.target

edit /etc/security/limits.conf and add before the end. remember kodi is the username, not the application. This will allow your user to get the audio thread a bit more priority.

kodi             -       nice            -1

Fake display-manager.service to not make plymouth or something else complain.

sudo ln -s /etc/systemd/system/kodi.service /etc/systemd/system/display-manager.service

#check ubuntu version
lsb_release -a

Add the stable or nightly repository and install kodi:

#stable 18
sudo add-apt-repository ppa:team-xbmc/ppa
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install kodi kodi-x11 kodi-inputstream-adaptive kodi-vfs-libarchive kodi-vfs-rar

#nightly 19 - combined x11/wayland/gbm version as of nightly 28/Oct/2020
sudo add-apt-repository ppa:team-xbmc/xbmc-nightly
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install kodi kodi-bin kodi-inputstream-adaptive kodi-vfs-libarchive kodi-vfs-rar

As we use openbox as our display manager, we need to auto start kodi, therefore create:

sudo mkdir -p /home/kodi/.config/openbox
sudo touch /home/kodi/.config/openbox/autostart
sudo chown kodi:kodi /home/kodi/.config -R

now we write the following into the created /home/kodi/.config/openbox/autostart file, this will automatically switch your TV to full range (please copy the lines, don't try to type the '` and so on, this code only works for one (1) connected TV, if you have multiple devices extend it to a loop):

OUTPUT=`xrandr -display :0 -q | sed '/ connected/!d;s/ .*//;q'`
xrandr -display :0 --output $OUTPUT --set "Broadcast RGB" "Full"
xsetroot #000000
xset s off -dpms
exec /usr/bin/kodi --standalone
while [ $? -ne 0 ]; do
exec /usr/bin/kodi --standalone
done
openbox --exit

Tweak the config further as per descriptions below depending on requirements (bluetooth, sound, boot logo, mysql database connection etc), otherwise start kodi:

sudo systemctl start kodi

System ->Player->Processing:
Enable HQ Scalers for scaling above: 20%
Allow hardware acceleration - VAAPI: on
Use Mpeg-2 VAAPI: Yes
Use Mpeg-4 VAAPI: if you like
UseVC-1 VAAPI: on
Use VP8 VAAPI: on (if your device supports it)
Use VP9 VAAPI: on (if your device supports it)
Use HEVC VAAPI: on (if your device supports it)

System -> Player -> Playback
Adjust Refreshrate to match video: On start / stop
Sync Playback to Display: On if you don't use passthrough and Off if passthrough enabled (* This makes no sense when you want to use passthrough, why? Read: 2107461 (post)). In current versions (Jarvis) passthrough is disabled by us if users wants to Sync Playback to Display to care for people that refuse to read.
Adjust display refresh rate to match video: On Start / Stop

While watching a SD(!) video, that is accelerated by VAAPI, e.g. mpeg-2 or h264, click the film role and choose: Deinterlacing-Method: VAAPI-MCDI or VAAPI-MADI (Sandybridge) and VAAPI-BOB (BYT), Scaling Method: Lanczos3 Optimized and choose save for all files. Remember to do this only in combination with the above "scaling above" for 20%. This Lanczos3 Optimized filter is too heavy for BYTs, here you might - depending on the file - choose Bilinear. (Hint the Deinterlace: Auto setting was removed some years ago - we can now properly detect interlace / non interlaced content).

It is obviously clear, that you won't see the VAAPI-MCDI settings when you play a video that is software accelerated only.

Possible ~/.kodi/userdata/advancedsettings.xml file for special needs:

You might need to create and advancedsettings.xml file as follows if you have special needs:
<advancedsettings>
  <loglevel hide="false">0</loglevel>
 <cputempcommand>sensors|sed -ne "s/Core 0: \+[-+]\([0-9]\+\).*/\1 C/p"</cputempcommand>
 <gui>    
   <algorithmdirtyregions>3</algorithmdirtyregions>
   <nofliptimeout>0</nofliptimeout>
 </gui>    
<video>
 <latency>
   <delay>50</delay>
   <refresh>
     <min>23</min>
     <max>24</max>
     <delay>175</delay> <!-- set to zero or adjust if audio seems out of sync with 24p movies -->
    </refresh>
 </latency>
</video>
</advancedsettings>

Color Management (only correct with above xrandr forced to FULL)

If your TV is limited range. Go to System -> Video Output and choose "Use Limited Range", disable Dithering.
If your TV is full range. Go to System -> Video Output and unselect "Use Limited Range" and enable Dithering with 8 bits.
If your projector is of low quality, use a dithering setting of 6 or 7 bits.

Remember the above settings only make sense, when you output in Full Range. With the default xrandr setting of Limited 16:235 - those settings would be totally wrong.

sudo vi /etc/default/grub

adjust the GRUB_CMDLINE_LINUX line to:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

commit the change using

sudo update-grub

Install animated kodi logo bootup theme:

git clone https://github.com/solbero/plymouth-theme-kodi-animated-logo
cd plymouth-theme-kodi-animated-logo
./build.sh
sudo dpkg -i plymouth-theme-kodi-animated-logo.deb

Enable graphical grub and store debug log as /var/log/plymouth-debug.log:

sudo vi /etc/default/grub

GRUB_GFXPAYLOAD_LINUX=auto
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash plymouth:debug=file:/var/log/plymouth-debug.log"
# plymouth:force-drm

echo FRAMEBUFFER=y | sudo tee /etc/initramfs-tools/conf.d/framebuffer && sudo update-initramfs -u

commit the change using

sudo update-grub

prevent update-grub from scanning all drives other than the boot drive for linux installations including usb sticks

sudo vi /etc/default/grub

GRUB_DISABLE_OS_PROBER=true

commit the change using

sudo update-grub

The Extended DIsplay Identification Data (EDID) is data that describes the capabilities of a digital display (DVI,HDMI, Displayport, etc) and E-EDID contains the audio capabilities as well.

NOTE: Kernel 4.4+ is required or audio EDID information won't be copied. Verify with

uname -a

First find the connected port (HDMI/Displayport):

ls -la /sys/class/drm
cat /sys/class/drm/card0-DP-1/status 
connected

edit /etc/default/grub and adjust the GRUB_CMDLINE_LINUX_DEFAULT with your port details and desired display resolution and refresh rate. Add D directly after the refresh rate for Digital output! Note the port info here does not start with “card0-”

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=HDMI-A-1:1920x1080@50D drm_kms_helper.edid_firmware=HDMI-A-1:edid/edid.bin"

Make sure the system was booted connected to the AVR/TV and everything is working. Then proceed to copy the EDID:

sudo mkdir -p /lib/firmware/edid
sudo cp /sys/class/drm/card0-HDMI-A-1/edid /lib/firmware/edid/edid.bin

Now we need to make a little hack and also convince ubuntu to load this edid.bin in initramfs. Create /etc/initramfs-tools/hooks/include-edid-data file and write into it:

#!/bin/sh

PREREQ="udev"
prereqs()
{
   echo "$PREREQ"
}

case $1 in
prereqs)
   prereqs
   exit 0
   ;;
esac

. /usr/share/initramfs-tools/hook-functions
# Begin real processing below this line

if [ ! -e "${DESTDIR}/lib/firmware/edid" ]; then
    mkdir -p "${DESTDIR}/lib/firmware/edid"
fi

if [ -r "/lib/firmware/edid/edid.bin" ]; then
   cp "/lib/firmware/edid/edid.bin" "${DESTDIR}/lib/firmware/edid/"
fi

manual_add_modules i915 radeon
exit 0

Make it executable

sudo chmod +x /etc/initramfs-tools/hooks/include-edid-data

Finish with

sudo update-initramfs -u
sudo update-grub
sudo reboot

First make sure Pulseaudio is not installed or if it is, uninstall it.
If there's a reference to snd_hda_intel in the output, then the kernel module has already been loaded as the driver:

sudo lsmod | grep snd

This command will list all sound devices. You'll need this to identify which sound device you wish to use later and to determine if there are multiple devices or just one.

sudo aplay -l

This command will show your model and codec chip to get further help via google in case of issues.

cat /proc/asound/card*/codec* | grep Codec

These two commands will show the current driver options for the sound models:

zless /usr/share/doc/alsa-base/driver/HD-Audio-Models.txt.gz

Apparently 2nd generation AFTV remotes use wifi instead of bluetooth.

The 1st gen AFTV remotes use bluetooth. They identify as

v1949:0401
  "[CHG] Device 5C:31:3E:80:FD:48 Modalias: bluetooth:v1949p0401d0112"

Fire TV stick remotes are from a different vendor and use v1949:0404

Setting up Kodi for use with MySQL (http://kodi.wiki/view/MySQL/Setting_up_Kodi):
do NOT use locally mapped network shares for kodi as otherwise the db entries will refer to localhost which won't work on other devices. Use generic smb or nfs paths instead. Ideally using fixed IP addresses for the NAS and not hostnames.

If you use passwords on your network shares then you will need to copy (or sync) your passwords.xml file from the userdata folder to each Kodi device.

Export the video and music library as nfo files to export an existing library from a device. If it's a new setup, ignore this.

edit or add to /home/kodi/.kodi/userdata/advancedsettings.xml

<advancedsettings>
  <videodatabase>
    <type>mysql</type>
    <host>***.***.***.***</host>
    <port>3306</port>

transfer userdata/addon_data and /addons from old to new server.
transfer Thumbnails if desired.

transfer:
/home/kodi/.kodi/userdata/passwords.xml
/home/kodi/.kodi/userdata/sources.xml
/home/kodi/.kodi/userdata/mediasources.xml

sudo chown kodi:kodi /home/kodi/.kodi/addons/* -R
sudo chown kodi:kodi /home/kodi/.kodi/userdata/addon_data/* -R

if amazon fire tv remote doesn't work properly - especially context menu key, create a custom keymap:
sudo vi /home/kodi/.kodi/userdata/keymaps/gen.xml
<keymap><global><keyboard><key id=“61952”>contextmenu</key></keyboard></global></keymap>
then reboot

on kodi, go to the video sources and for each define the content and update the library. This will take a while.

If multiple Kodi instances should share video/music thumbnails, the following lines need to be added to the advancedsettings.xml to redirect Kodi's special folders to a NAS drive:
edit or add to /home/kodi/.kodi/userdata/advancedsettings.xml

      <substitute>

put the file script.xbmc.boblight.keymap.xml into your “userdata/keymaps” folder.

You can access the settings during playback by hitting the key “b” or “B”. (Note: a former keymapping to that key will be overwritten by this keymap file. If there is a
conflict you just can change the mapped key to something else).

script.xbmc.boblight.keymap.xml:

<keymap>
  <fullscreenvideo>
    <keyboard>
      <b>Addon.OpenSettings(script.xbmc.boblight)</b> <!-- shortcut key b to boblight settings -->
      <B>Addon.OpenSettings(script.xbmc.boblight)</B> <!-- shortcut key B to boblight settings -->
    </keyboard>
  </fullscreenvideo>
</keymap>
