Videos with HLG seem to be broken with the current iteration of drmprime-2img-no-ffmpeg-bump branch. The TV does not switch to HDR mode.

mod edit ---
current LE11 nightlies include now everything that is required to have HDR at LE, no more special builds are required

I an about to try pine-64
Trying Generic x86 would be a better idea.
-
How exactly does it fail with nightly? The latest nightly should work in theory. Kernel 5.16 does support Alder Lake CPUs.
-
Core i5 -12400
Use the nightly.
-
The link should work now.
-
an use YCbCr 4:2:0 instead of RGB for intel gpu?
Only YCbCr 4:2:0 8-bit. And it's not configurable via userspace.
-
There is no HDR in Generic nightlies.
-
I will compile an updated build at some point.
lrusak's Kodi HDR branch hasn't been updated since September. HDR commits from that branch don't apply to a current Kodi master.
-
Are all the patches for HDR smp uses in his builds already in the nightlies?
No.
-
Try the build that I posted here. Someone said that it worked on their AMD Vega M box.

Try to disable "Input Signal Plus" in General -> External Device Manager on your Samsung TV.

MMAL advanced is perfectly usable for 1080i on RPi3.

HDR is supported for 4K 50/60Hz, just not at the optimal color depth.
In my build I enabled GPU dithering for 8-bit modes to eliminate color banding for 4K 50/60Hz.
-
but color set 24bit if i use 4K & 60/50Hz
Limitation of the Intel kernel driver. It can only do RGB/YCbCr 4:4:4, so deep color is not possible with 4K 50/60Hz.

Haven't tried AV1 videos yet but I'm assuming those are not fully hooked up (hardware-decode wise) in non-smp buids as well.
Jasper Lake does not support AV1 decoding in hardware. Only TGL/RKL/ADL support this.

Making a kernel patch for TBS 6905 from TBS sources should be doable if not trivial. I don't see any other solution for TBS for now.

LibreELEC-Generic.x86_64-11.0-devel-20211020222733-d3745e7.img.gz
This is from Oct. 20 master branch (Kodi 20) with the Atmos patch included.
