From the log it indeed looks like a corrupted file and ffmpeg trips over that:

The start up rainbow swirl of Hyperion happens right on the LibreElec bootscreen no matter how much time I put in the config file.

Do you have any idea why that might be? I put your code into a file "delay.conf" in a new folder "service.hyperion.service.d" into the "system.d"-folder. Thanks for your help!

Run systemctl status service.hyperion and check if it has correctly picked up the delay.conf drop-in. You should see the systemd service loaded from the kodi addon-folder and the Drop-In loaded from the systemd config folder

It's probably easiest to configure it in Kodi: Settings->System->Display, set resolution to 1920x1080p and refresh rate to 60Hz.

I'd also recommend changing the settings level to Expert and set up the whitelist to enable 1920x1080 60/59.94/50Hz (and probably also 1280x720 60/59.94/50 Hz, then Kodi can output 720p and let the TV scale up). Ah, and set Adjust display refresh rate in Settings->Player->Videos to Always or On start/stop.

ISTR the default audio player (paplayer) doesn't do any additional caching (like the video player).

You can tell kodi to use the video player to play audio files, then it'll use the video cache and you can tweak it's settings if needed.

eg create /storage/.kodi/userdata/advancedsettings.xml with the following contents:

<advancedsettings>
  <audio>
    <defaultplayer>VideoPlayer</defaultplayer>
  </audio>                                    
  <cache> 
    <buffermode>1</buffermode>
    <readfactor>10</readfactor>
  </cache>                     
</advancedsettings>

Try adding audio_pwm_mode=1 to config.txt.

Just delete the profiles.xml file, Kodi will then use the default one.

BTW: A fix for the kodi crash with empty or corrupted profiles.xml was PRed a couple of days ago, if everything works out fine it should be included in the next Kodi / LE releases.

It's an issue in the RPi firmware (the dispmanx grabber to be specific), grabbing at 4k needs too much (RAM) bandwidth. The RPi developers already know about that and it's on their TODO list (but probably not too high priority). Not much we can do about it for now other than wait for a firmware update.

Hardware deinterlacing isn't implemented for RPi4 yet. It'll come, but no ETA on that.

I posted a workaround for the no-signal issue after kodi start here: Hyperion addon does not work with inputstream.adaptive (Netflix etc.) with Pi4

Note that disabling 1080p GUI limit or playing 4k videos will also result in "no signal" if hyperion is active. That's a known issue and currently there's no workaround available.

vpeter the issue is already fixed in master binutils: explicitly depend on target zlib by HiassofT · Pull Request #4013 · LibreELEC/LibreELEC.tv · GitHub 9.2 backport [le92] binutils: explicitly depend on target zlib by HiassofT · Pull Request #4014 · LibreELEC/LibreELEC.tv · GitHub should be merged soon.

Check the setup of your TV, usually you also have to enable "Ultra HD Deep Color" in the HDMI port settings.

Yes, I'm using an Arduino (SPI is used by my audio card). Not sure if this makes a difference as I could also reproduce the issue on my setup once I dropped 4kp60 in config.txt.

Very puzzling, not quite sure what's going on.

I've attached my /storage/.kodi/userdata/addon_data/service.hyperion/hyperion.config.json file, please keep us posted if you find something.

No, I haven't tested without the Arduino. Can't easily do that as LED strip and arduino are all attached behind my wall-mounted TV.

I wouldn't rule out there's some problem with direct attachment, but as I said I can't really check myself.

Hias

I think I could reproduce the issue, also got occasional black screens after I dropped "hdmi_enable_4kp60=1" in config.txt.

Can you check if adding that setting to config.txt fixes the black screen issue for you?

Even if you just have a full HD TV and no need for 4kp60 output that setting should clock some core parts of the RPi a bit higher, maybe that's what's needed to get rid of the black screens...

Hias

Yes, please uninstall the old hyperion version and test with the hyperion addon from the LibreELEC repo - would be good to rule that out as it's a possible source for the issue.

Just tested with your images, everything fine here.

Watching your video rang a bell, though, I remembered having a very similar issue back then when I first tested my LED strip but was using a power supply with too low power rating. If I raised the LED brightness beyond a certain point the strip would just shut off completely. This was most easily to reproduce with white light (as this means all three R/G/B LEDs are active at the same time).

Not sure why that also happens with green and why it was OK on the RPi3, but as it's rather easy to test and would provide some interesting datapoint please give it a try:

Start up hypercon, connect to libreelec and then pick white on the color-wheel. Then change the brightness (on the vertical slider to the right) and check if the LEDs turn black at some point. Checking with other colors (yellow, green etc) may also be interesting.

Yes, 2GB will work fine for 4k playback.

If you feel the itch to have more memory then spend the additional 10 bucks for the 4GB version, it won't hurt but isn't necessary for 4k.
