I still think it is a codec issue in the nightly build.
It's an issue with Intel media-driver. The fix is already in the media-driver master branch. I compiled and tested a build with an updated media-driver and HW acceleration works fine on my i5 12400 box.
I assume you are using rpi kernel 5.15.18.
Looking at the git commit history it looks like this commit was merged to kernel 5.15.17, so you may want to revert it for testing.
Your CPU is too weak to decode 4K video in software.
I believe that current LE master does support nvidia after this PR. The image has to be built with Wayland (PROJECT=Generic ARCH=x86_64 DEVICE=wayland).
Just copy the image to storage/.update and reboot
I posted a newer build here. No idea if anything changed for AMD.
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.
