The only downside is that 4k tops out at 30fps since it only supports HDMI 1.4
Not sure why that spec page says HDMI 1.4. Gemini Lake SoC has a built-in HDMI 2.0 controller. HDR is not possible with HDMI 1.4.

I am having issues playing certain MP4 files in this build.
Software decoding does not seem to work with DRM PRIME. Disable "Allow using DRM PRIME decoder" and it will play.
-
Build in post #698 is the latest and greatest. And probably the last one from me, at least until lrusak resume his work on HDR. No idea why it crashes for you, those builds are rock stable on my J4105 box.
-
DRM PRIME options are present in my builds.

You should try a clean install rather than updating over LE 9.
-
Well it booted... but unfortunately there was just a black screen when trying to play HDR content. Any content for that matter
Switch PRIME Render Method to EGL.

A build with enabled AMD graphics - LibreELEC-Generic.x86_64-10.0-devel-20210601032257-86a07cd.img.gz
@libreAU you can try it but as I said HDR does not work on my Vega 3 AMD box.
-
I just don't think smp builds with amd graphics enabled
I removed Radeonsi mesa driver from my builds because HDR does not work on my Athlon GE200 (Vega 3) box and a clean build of LE compiles significantly faster without LLVM/radeonsi.

Theelichtje I don't know if this is applicable to your Onkyo model... hdmi_4k_onk.pdf

PC is a Celeron J4105
What motherboard? Is HDMI connected directly to the TV?

The blank screen is the point when Kodi switch to a correct video mode.
Use mkvtoolnix.

The only issue I noticed is, when I start an HDR movie like Samsung Wonderland Two HDR UHD 4K Demo:
The movie starts and after a couple of seconds the screen goes blank (and the audio stops) for about two or three seconds.
Is it a .ts file? For some reason it takes a while for Kodi to switch to a correct video mode when starting a playback of .ts files. You can remux it to mkv and it will start properly.

Updated Kodi 19.1 build:
LibreELEC-Generic.x86_64-10.0-devel-20210524004323-f9d2c33.img.gz
Twooter try this^ updated build.

It will run on any HDR-capable Intel hardware.
-
Yes, this is from Matrix branch (19.1) + HDR patches. I don't expect any issues with settings but back them up first, just in case.
