Odroid C4 | Kodi video playback stutter

rainfallsevensamurai commented 3 years ago

Creating a bug report/issue

Required Information

DietPi version | 7.1.2
Distro version | Buster
Kernel version | 4.9.241-arm64 #1 SMP PREEMPT Thu Feb 25 17:57:15 CET 2021 aarch64 GNU/Linux
SBC model | Odroid C4/HC4 (aarch64)
Power supply used | 12V 2A
SDcard used | 32GB eMMC Module

Additional Information (if applicable)

Software title | Kodi
Was the software title installed freshly or updated/migrated? Freshly installed using dietpi-software
Can this issue be replicated on a fresh installation of DietPi? It is a fresh installation

Steps to reproduce

Obtain Odroid C4
Flash image from dietpi website
Mount NAS drive using dietpi-config
Install Kodi using dietpi-software
Set Kodi to autostart
Reboot
Connect Odroid to TV
Open file from NAS to play in Kodi

Expected behaviour

The video and sound should play smoothly

Actual behaviour

The video stutters and the sound is barely audible.
If you pause the video it continues a while until it 'catches up'

Extra details

Installed software: PiHole, Unbound, Deluge (which is also not working: service is running but cant be reach via browser or application, see https://github.com/MichaIng/DietPi/issues/4397), VPN via Wireguard
I'm not sure how fast they should be, but there's a wired connection from the Odroid to the router and a wired connection from the router to the NAS. If I run the provided speed check, I got

DietPi-Benchmark Filesystem Benchmark Results:

Filepath = /mnt/nas218video/benchmark.file
Test size = 100 MiB
WRITE = 4 MiB/s
READ = 6 MiB/s

I found a related thread here: https://github.com/MichaIng/DietPi/issues/2584

At the moment I'm really unsure of what's happening. The Odroid seems to be under no stress at all playing the video. Yesterday I killed the kodi process from ssh and started it myself using kodi --standalone. When I played a video I got messages in my ssh session like:

codec_init amstream version 2.0 [codec_pause]p->has_audio=0 video_pause! ...etc

I tried playing videos in different formats, h264 and h265, etc.

Anything I can check to help investigating? Thanks so much for your time!

MichaIng commented 3 years ago

Many thanks for your report.

You read he file from a network drive? 6 MiB/s read speed is very slow. Did you test it from a local hard drive or with an SD quality video?

rainfallsevensamurai commented 3 years ago

I'll try to test with a 'local' file which I'll upload with FileZilla to /mnt/dietpi_userdata. I'll get back to you.

rainfallsevensamurai commented 3 years ago

Uploaded the file and added it to Kodi. Plays just as bad. Exactly the same behavior. Info from Kodi (uses o to display information on screen while playing):

Video decoder: am-h265 (HW)

MichaIng commented 3 years ago

Btw, you did install the Odroid build of Kodi, right (done when using dietpi-software)?

dpkg -l | grep -E '(kodi|aml|mali)'

And required kernel modules are loaded?

lsmod

And you did try to start Kodi as root user, right?

rainfallsevensamurai commented 3 years ago

Yes, I did install using dietpi-software, autostart as root.

MichaIng commented 3 years ago

That all looks pretty correct. I'll have a look into the Kodi executable script...

Can you try to start it (as root) without --standalone flag?

kodi

rainfallsevensamurai commented 3 years ago

Did that. Played a local file from /mnt/dietpi-userdata/. Still the same stutter.

[codec_reset:1220]ret=0
[codec_pause]p->has_audio=0
video_pause!
[codec_reset:1220]ret=0
[codec_pause]p->has_audio=0
video_pause!
[codec_reset:1220]ret=0
[codec_pause]p->has_audio=0
video_pause!
[codec_reset:1220]ret=0
[codec_pause]p->has_audio=0
video_pause!
[codec_reset:1220]ret=0
[codec_pause]p->has_audio=0
video_pause!
[codec_reset:1220]ret=0

This goes on and on and on.

ps: not sure if related, but when I Ctrl + C the Kodi process, my screen resolution goes way up and the outermost pixels are not visible, the text I see is cropped.

rainfallsevensamurai commented 3 years ago

Ok, I did a clean install, flashed the mmc module again I mean. Installed Kodi, used dietpi-drive_manager to mount my NAS. Opened Kodi and added some files from the NAS to the library. The same problem, fps would not go over 10 when playing a video. Then I started tinkering with Kodi settings. Found this:

Settings > Player > Videos > Processing > Allow hardware acceleration - amcodes: True

When I set it to False all videos started playing great with fps > 29. I'm still confused however :)

MichaIng commented 3 years ago

Hmm, these should be the Amlogic hardware acceleration which we explicitly try to have enabled here 🤔.

Another test, starting Kodi via:

/usr/local/lib/kodi/kodi-aml

And can you check the following:

ls -lL /sys/class/video/axis /sys/class/video/screen_mode /sys/class/video/disable_video /sys/class/tsync/pts_pcrscr /sys/class/audiodsp/digital_raw /sys/class/audiodsp/digital_raw /sys/kernel/debug/aml_reg/paddr /sys/module/ionvideo/parameters/freerun_mode /sys/class/video/freerun_mode /sys/class/amhdmitx/amhdmitx0/config /sys/class/vfm/map /sys/class/tsync/enable /sys/class/amhdmitx/amhdmitx0/frac_rate_policy /sys/class/display/mode
find /sys/class/ -maxdepth 2 -name 'am*' -exec ls -lL {} +
find /sys/class/misc/ -maxdepth 1 -name 'mali*' -exec ls -lL {} +

rainfallsevensamurai commented 3 years ago

I started Kodi again using the code you provided. I re-enabled the hardware acceleration in settings and tried to play a video. None would even start playing. Memory and CPU go way up, but nothing happens.

Okay so currently only root user has full access. Some files have no write permissions at all, but I guess it's expected for those which are only to read information from but cannot be used to set/change/communicate with the hardware. However, to rule anything about that out, the following could be tested:

chmod 0666 /sys/class/video/axis /sys/class/video/screen_mode /sys/class/video/disable_video /sys/class/tsync/pts_pcrscr /sys/class/audiodsp/digital_raw /sys/class/audiodsp/digital_raw /sys/kernel/debug/aml_reg/paddr /sys/module/ionvideo/parameters/freerun_mode /sys/class/video/freerun_mode /sys/class/amhdmitx/amhdmitx0/config /sys/class/vfm/map /sys/class/tsync/enable /sys/class/amhdmitx/amhdmitx0/frac_rate_policy /sys/class/display/mode
find /sys/class/ -type f -maxdepth 2 -name 'am*' -exec chmod 0666 {} \;
find /sys/class/misc/ -type f -maxdepth 1 -name 'mali*' -exec chmod 0666 {} \;

This is only temporarily, so after reboot the permissions are back to default.

rainfallsevensamurai commented 3 years ago

Sorry for the delay. Above suggestion had no effect, whenever I enable HA the videos won’t load or play extremely slow.

MichaIng commented 3 years ago

Okay. I'll check this back with Meveric. Good to know that disabling hardware acceleration leads to acceptable frame rates, although CPU usage will be high I guess (?).

rainfallsevensamurai commented 3 years ago

Yes it is. Thanks for checking...

MichaIng commented 3 years ago

@meveric Another one where I'm not sure what the issue is and if we miss something:

Mali driver is installed
Amlogic libraries are installed
The related Kodi package is installed
Kodi is started outside of X11
Permissions are not the issue, Kodi runs as root user anyway
amcodes for hardware acceleration is found and enabled, but it seems to work even better when disabled

meveric commented 3 years ago

Hardware accelerated video decoding on C4 is always a bit of a hassle for me. Overall the basics all seem to be correct, but I also experienced issues with hardware decoding on the C4 via Kodi. My guess is that maybe the aml-libs-odroid could cause some issues, and I have to try if the once from HardKernel work anyway different. Problem with those is, that they are not packaged correctly and I have to rebuild the package with the correct placement of files first before I can try this.

It's a long time standing issue for me, with very little priority up to now, as most people normally use OpenELEC or something instead.

I need time to investigate this, please don't expect any results in the next couple of days.

MichaIng commented 2 years ago

I'll mark this as closed. New Bullseye image uses the Debian Kodi build and GBM when not started from desktop, so things may be pretty different. I'll do tests on Odroid N2 currently, and result should be pretty similar on C4.

rainfallsevensamurai commented 2 years ago

Today I tried dietpi again, because I was notified by github about this issue being closed. Did a clean install using a fresh download. Used dietpi-software to install Kodi. It doesn't even start.


Failed to open zone.tab
ERROR: Unable to create GUI. Exiting

I know you're working very hard on dietpi and I respect the huge amount of support you're giving, but I can't understand why this issue got closed while the problem got worse.

MichaIng commented 2 years ago

Many thanks for your feedback. I have an Odroid N2 here since a few days an will do Kodi testing on it, which should behave very similar to the C4.

How did you try to execute Kodi? It should be the package from Debian now which has X11 support as well as GBM support included, so it should work in any way. Important only to not start it from desktop via GBM, as DRM allows only one exclusive device access.

rainfallsevensamurai commented 2 years ago

I connected my c4 to a screen and keyboard. At boot I login with root and type kodi

Tried kodi —standalone as well. Tried auto boot to kodi too. All give the same message.

Could you point me to a place to find extra logging please?

GetDirectory - Error getting /usr/lib/aarch64-linux-gnu/kodi/addons

Hmm, the Kodi package itself does not ship this directory or any addons. Probably you have/had kodi-addons-odroid installed, or manually installed and enabled addons in Kodi, and the new version now looks for them at a different place?

Please check the following:

dpkg -l | grep kodi

Although you did that already above, and mentioned package was not installed.

Please check whether starting Kodi with a clean config works:

mv ~/.kodi ~/.kodi_bak
kodi

And does this exist?

ls -l /usr/local/lib/kodi/addons
ls -l /usr/lib/kodi/addons

About the DRM errors, I hope GBM is generally supported by this C4 kernel. Can you check:

ls -l /dev/dri

Joulinar commented 2 years ago

The missing addon directory I faced as well on my test system today. Looks like it has been introduced with 19.3

rainfallsevensamurai commented 2 years ago

I did a complete clean install of dietpi, so no legacy settings.

Clean config for Kodi gives the same error.

MichaIng commented 2 years ago

root@DietPi:~/.kodi/temp# ls -l /dev/dri ls: cannot access '/dev/dri': No such file or directory

Ah okay that explains it, no DRM interface. This means Kodi need to be started via X server then:

dietpi-software install 6
xinit "$(which kodi)"

or from within a desktop session, where it should work OOTB. That is definitely no improvement. I'll experiment with the upstream kernel on Odroid N2 tomorrow, which should provide the DRM interface.

... through wait a second, I remember there was an alternative device tree ... yes, the Odroid N2 has an meson64_odroidn2_drm.dtb which can be used to enable DRM (pretty sure based on the name), but on C4 this does not exist 😢.

Looks like it has been introduced with 19.3

Obviously in 19.1 from Debian it's the same. To be true when things worked, I never had a look into the Kodi logs, so probably this is not really an error but more an info that no external addon package was installed. For example an HEIF image decoder can be installed which contains this directory: https://packages.debian.org/bullseye/arm64/kodi-imagedecoder-heif/filelist Just misleading that Kodi logs this as ERROR...

@rainfallsevensamurai Just to rule it out, can do do a list test:

dpkg --force-depends -P malig31-fbdev-opencl-odroid aml-libs-odroid
apt install --reinstall libegl1 libgles2 libdrm2 libgbm1
kodi

The malig31-fbdev-opencl-odroid package is an explicit fbdev (framebuffer driver) one, hence not an KMS/DRM one, so that may break it, while Debian's EGL/GLES packages are explicitly also build for KMS/DRM usage. At least this sounds logic, let's see whether it helps.

libegl1 : Depends: libegl-mesa0 but it is not going to be installed

Hmm, there seems to be still something left. What does this show:

apt install libegl-mesa0

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 kodi-bin : Depends: libegl1
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

APT hassle 😄:

apt install libegl-mesa0 libegl1

rainfallsevensamurai commented 2 years ago

That worked, but the problem persists. Kodi doesn't start. Here are the errors from the kodi.log file again:

I really appreciate the work you're doing, but maybe I would like to take a step back and remind myself why I'm doing this. I just wanted to run Kodi and some other applications on the same machine. This shouldn't be that hard. Before you closed the ticket I used CoreELEC for a while. It really just worked great. I gave dietpi another change because I really want to run pihole and deluge on the same machine. I don't want to sound entitled, but maybe dietpi should inform potential new users of its supported applications on the website. Sometimes I feel like I'm the only one that uses dietpi on a Odroid C4 and have this strange request I want to use this little, obscure piece of software called Kodi :D

Again, I'm willing and able to debug and test for a certain period, but I would also like to see a movie once in a while. If dietpi doesn't support kodi on a C4, that's ok. But then I would like to know, so I can move on.

MichaIng commented 2 years ago

Have you tried what I suggested above, running it via X server?

xinit "$(which kodi)"

If the X server (xinit) not installed yet:

dietpi-software install 6

I don't want to sound entitled, but maybe dietpi should inform potential new users of its supported applications on the website.

That would be great, however, as long as we do not have individual "maintainers" for every software title which then also do test it on every SBC, or the other way round, this currently cannot be achieved. Very most software works fine on every SBC and implementations break rarely, but GUI/GPU related software is really a special difficult case, since it highly depends on the exact kernel, GPU drivers, libraries, GUI software builds etc and all of these need to work together. And I have not the SBCs and not the time to test each of them regularly on every SBC. And then e.g. on RPi different available sound drivers and configs come on top, which make it again more complicated. So it depends on user reports when something does not work.

In this particular case it was the upgrade from Buster to Bullseye which broke Kodi since on Odroids it is a dedicated Build (which utilises the framebuffer driver and not KMS/GBM/DRM), while there is no such Kodi build for Bullseye yet and I wasn't aware that those Odroids don't have a DRM interface at all, though it makes sense this being the reason for the fbdev/framebuffer drivers and builds 😉. Such a Debian upgrade happens every two years, so naturally implementations can then break. It will be much more reliable when we switch to Debian's own packages, away from those special SBC-dependant builds, but obviously this requires a more generic kernel then as well. As said, I'll test the Armbian mainline kernel for Odroids N2 and C4, which hopefully provides the DRM interface so that we can use regular Debian GUI libraries and packages which are assured to be maintained and tested by Debian itself 🙂.

Thank you for your explanation!

I installed X server without problems and then tried your suggestion:

This did in fact start Kodi 19.1 (!). I have not been able to test it yet, to see if it works, plays without stutter and utilizes the hardware acceleration. I'll keep you informed.

Ok that’s incredibly slow. I couldn’t even start a movie, the interface takes 2 seconds to respond to each input.

MichaIng commented 2 years ago

We updated our image to use mainline Linux with generic DRM/KMS support. The issue shouldn't apply anymore, I hence mark this as closed.
