Jetson/Kodi (XBMC)

Kodi (XBMC) for Jetson TK1
Current status: Full hardware-accelerated video decoding & rendering, with GLES/EGL and OMX on X.Org.

Installation
If you have old non-PPA version installed, remove it first and delete all old Kodi settings (be sure to take a backup, if you have made any special settings): sudo apt-get remove xbmc xbmc-bin rm -rf $HOME/.xbmc

If you have not yet enabled universe, enable it now: sudo apt-add-repository universe

Add PPA for the Kodi, update and install Kodi: sudo add-apt-repository ppa:kulve/xbmc-jetson-tk1 sudo apt-get update sudo apt-get install kodi

If you want to include PVR support then you will need to install the correct PVR add-on. Run the following to find which add-on's are available: (sudo) apt-cache search xbmc-pvr

Then install the one relevant using: sudo apt-get install

PVR Clients
If the above easy steps don't work or you just want the latest then you can get them here.

If you dont have git, install it (you also wont have other stuff): sudo apt-get install git autoconf libtool build-essential

Now clone the pvr add-on's: git clone https://github.com/opdenkamp/xbmc-pvr-addons.git

Jump to the newly created dir: cd xbmc-pvr-addons/

Now following the instructions on the wiki: ./bootstrap ./configure --prefix=/usr/share/kodi/ make install

The easiest way is to create a zip and install from zip: ./bootstrap ./configure make zip

Performance Tips
It seems Kodi only uses the CPU cores that are online when Kodi starts, so I recommend maximizing CPU performance before starting Kodi / XBMC.

For 4k/UltraHD/2160p TV you need to set the maximum GPU frequency as well.

Commands to adjust performance only last until a reboot (or until something else changes them), so you can add commands to your "/etc/rc.local" bootup script if you want them to be run automatically on every boot. It's possible that something may change them later if you don't use Kodi soon after bootup, so you might want to also run "sudo /etc/rc.local" again just before starting Kodi / XBMC.

Full details about adjust these are on the Jetson Performance page, but for Kodi / XBMC with hardware decoding, it is usually good enough to just force all CPU cores of Jetson TK1 online on every bootup, without forcing the CPU to run at max clock speeds.

So open the bootup file on Jetson: sudo nano /etc/rc.local

And enter these contents: echo 0 > /sys/devices/system/cpu/cpuquiet/tegra_cpuquiet/enable echo 1 > /sys/devices/system/cpu/cpu0/online echo 1 > /sys/devices/system/cpu/cpu1/online echo 1 > /sys/devices/system/cpu/cpu2/online echo 1 > /sys/devices/system/cpu/cpu3/online exit 0
 * 1) Turn on all 4 CPU cores, so that Kodi / XBMC sees them when it starts.

And if you want max performance such as for 4K / Ultra HD / 2160p video, also add these extra commands to the file above, just above the "exit 0" line: echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor echo 852000000 > /sys/kernel/debug/clock/override.gbus/rate echo 1 > /sys/kernel/debug/clock/override.gbus/state
 * 1) Use max CPU performance.
 * 1) Use max GPU performance.

(For more details about how to adjust the CPU and GPU performance, go to the Performance page).

Playback Quality Tips
Use Kodi Audio configuration under system settings to enable HDMI audio.

For jitter free video playback I recommend allowing Kodi to to adjust TV refresh rate always. For that you need to enable the Expert Settings and enable "Adjust display refresh rate to match video". For instructions, see: http://wiki.xbmc.org/index.php?title=Settings/Videos

With limited testing I suggest selecting Audio Clock as the A/V sync method.

Testing Betas
To test the latest version (currently 15.1rc1), simply add the testing PPA, update, and install. sudo add-apt-repository ppa:kulve/kodi-testing-jetson-tk1 sudo apt-get update sudo apt-get install kodi
