Nanopi-a64 running kodi

This is a prebuilt Ubuntu 18.04 minimal image with linux 4.20.17 / 5.3.y to run Kodi.

Kernel features on NanoPi A64:

  • camera (ov5640)
  • cedrus (VPU)
  • mali (GPU)
  • hdmi
  • hdmi-sound
  • wifi
  • eth 100 Mbps / Gbps
  • ir
  • v4l2

Tested with Kodi 19.0 ALPHA1 and Kodi 18.3 RC1

Brief description of the OS Image

not too heavy not too light would fit precisely how we want it to be. This is a CLI (Command Line Interface) image with minimal packages so you can run Kodi while you can still have a powerful Linux to extend and play with. Eventually, this will be upgraded to Kernel 5.2 when time permits.

What works and what not (simple table)

This is a WiP (Work in Progress) and intended for learning purpose, what does not work today may work tomorrow but you can consider the kernel very stable.

Here is a very simple table to show the state of this work.

ir has been tested with this procedure:

Enable the right protocols for your TV control, in this case NEC

ubuntu@nanopi-a64:~$ sudo su
root@nanopi-a64:/home/ubuntu# echo nec > /sys/class/rc/rc0/protocols
root@nanopi-a64:/home/ubuntu# exit
exit

Camera (OV5640)

Camera is enabled by default to work with latest OV5640 and sun6i_csi mainline kernel and you will need a special version of ffmpeg to be able to use HW encoder. Encoding via xlib64 has poor results. Be careful if you build any ffmpeg that can break KODI, KODI is highly dependent on a special ffmpeg version done by Kwiboo. Build any ffmpeg statically if you need ffmpeg.

ffmpeg -video_size 640*480 -pixel_format yuv420p -i /dev/video0 out.mp4

Using cap also need a tweak to work with sun6i_csi.

V4L2 works somehow but there are some compatibility issues i would say.

v4l2-ctl --list-devices
cedrus (platform:cedrus):
  /dev/video1

sun6i-csi (platform:csi):
  /dev/video0

Check video0 capabilities:

v4l2-ctl -d /dev/video0 -l

Limitations

640x480 window size only, 30 FPS or 60 FPS. Quality below average.

Sound

hdmi-sound works very nice, spdif / analog (jack) i could not figure out how to make it work.

CEDRUS and Mali

This work's done by Maxime from Bootlin.

KODI

Kodi 18.3 RC1 has been working fine with kernel 4.20.17 (unfortunatelly EOL) as of the tests.

To run Kodi type in shell:

kodi

Limitations

  • H265 does not work. (fixed)
  • 10 bit not works. (fixed)
  • No 4K(yet)

Patch set

Patches has been applied manually in order to make it usefull. Contact the authors if you need help.

  • Enable Wlan0

    sudo apt-get install wpasupplicant

    Edit /etc/network/interfaces and add/change

    allow-hotplug wlan0

    Wlan0 is lazy to accquire the IP from the DHCP, it takes a few seconds. Check wlan0 IP:
