[SOLVED] Kodi on RPi4 aarch64: video decoding is not working

Postby doragasu1 » Sat Apr 10, 2021 7:24 pm

I had a running 32-bit setup on a RPi4, but I decided to move to 64-bits (mainly to avoid some problems with oom_killer) and I migrated all the setup to aarch64. So far I have everything working flawlessly, excepting Kodi.

Kodi starts OK, but first the UI moves very slowly. And worse, when I try playing a video, it seems to start but the video does not play. Image stays on the menus, the play overlay bar on the bottom on the screen pops and depending on the media sometimes I get sound, but the video does never appear.

I suspect that maybe this is the expected behavior on aarch64 and there is no hardware decoding support. Reading here that´s what it seems to me. But if I go here, it seems that you should be able to play media files...

I am using kodi-rpi (also tried with kodi-rpi-git with same result). My /boot/config.txt has only 2 lines:
Code: Select all
enable_uart=1
include kodi.config.txt


And when I play a file, this is what appears in the logs:

I see several errors, but I have no idea what they mean.

So is hardware decoding supported? Is there anything I can do to make Kodi work?

Re: Kodi on RPi4 aarch64: video decoding is not working

Postby graysky » Sat Apr 10, 2021 7:41 pm

Yes, HW decoding is supported under all packages/aarch64 and armv7h. Not sure if it matters but /boot/config.txt:
Code: Select all
[all]
include kodi.config.txt


Reboot after modifying that. Try a test clip: https://www.jell.yfish.us/media/jellyfi ... d-hevc.mkv

Post the entire kodi.log with debug enabled.

Thanks for help. Now my /boot/config.txt is:
Code: Select all
enable_uart=1

[all]
include kodi.config.txt


If I remove the enable_uart=1, the machine does not boot, BTW.

Test file did not play, same behavior. The full log with debug info is located here: https://pastebin.com/dkLyuHsY

I think the most relevant parts are:

And these errors keep repeating until I shut Kodi down.

Are you using linux-aarch64 or linux-raspberrypi4? Guessing aarch64. You need HW decoding in the linux-raspberrypi4 kernel for it to work/mainline kernel doesn't provide them.

Wohow, that was the missing piece in the puzzle, playback works flawlessly now. Thanks a lot!

I followed the installation guide here, and maybe it needs to be updated, because unless I screwed something during the process, it installs the aarch64 kernel, but the guide states "This installation has near full support for the device, including the VC4 graphics". Also when I installed the linux-raspberrypi4 kernel, they system panicked on boot because it could not mount the root filesystem. I had to grab the SD and edit /etc/fstab to change mmcblk1p1 to mmclbk0p1, as with the armv7 install.

(now I have to guess why kodi it is not mounting external USB devices as with my previous install, maybe I installed something I forgot)

I added the rpi kernel to the optdepends array to avoid confusion. As to automounting USB, I couldn't get it working with v19. See here which has gone unanswered.

Weird because it worked perfect for me with v19 on the 32-bit install. And it was not udisks2 or any other daemon as far as I recall, because drives were mounted in /var/run/kodi/whatever.
