Display MoreI compiled a new build with the following changes:
- AV1 VAAPI hardware decode (owners of TGL/RKL please test)
- added unmerged AV1 ffmpeg fixes:
github.com/intel-media-ci/ffmpeg/pull/403
github.com/intel-media-ci/ffmpeg/pull/412
LibreELEC-Generic.x86_64-10.0-devel-20210715034851-adbfe1e.img.gz
I tried this build on my NUC and it keeps rebooting every 5-10 mins. Gonna roll back.
Run
paste /sys/class/drm/card0-HDMI-A-2/edid
and post the ix.io link here.
Sorry I fell asleep

Does it crash during playback?
EDID looks ok, no idea why Kodi is limiting to 1080. Try a clean install.

Yes, I did everything as a clean installation ...
Am I to understand that the problems around the intel 750 graphics drivers have already been solved?
Is Mesa Intel Graphics (RKL GT1) a driver that should support 4K @ 60? Does it work for anyone?
I don't know if it's worth mentioning, but the official version of libreelec won't even start. Lists the missing graphics driver.
Does it crash during playback?
Yes, both during playback and just sitting still and doing nothing. I can provide a pasetbin dump of the kodi crashlog, if that helps?
FYI - the build in post #698 is more stable. It only crashes like 2 times per day. This latest image in post #751 crashes every 10-15 mins, and sometimes does a triple or quadruple crash loop.
I am using a NUC NUC8i5BEK

Is Mesa Intel Graphics (RKL GT1) a driver that should support 4K @ 60?
No, it is kernel i915 driver. Mesa is OpenGL/GLES stuff. Kernel 5.13 should properly support RKL, so I'm not sure what the issue is.

No crashes at all on my box. Must be something specific to your NUC.
J4205-ITX This latest image in post #751 & 754 crashes random.

I found out that via DP on the LG monitor it works fine 4K@60.
It is also strange that it is not possible to select another output in the video output settings. (at least HDMI / DP or default)
I have a TV and a projector connected to the Asrock J5005 and it works there.
Is it unrelated to the fact that the HDMI 2.0 native 4K@60 is on the RKL?
I have Asrock Z370 and i3-9100 and there is an integrated LSPCON DP to HDMI 2.0 chip.
The question is whether it is possible to adjust the Libreelec settings so that the 4K signal is on the native HDMI 2.0 output.
According to the sound output, I feel that it's HDMI#0 as in the picture.
/I tested KODI on RKL 11600 + ASRock H570m via Win10, and it goes via HDMI 2.0 4K@60/
I have downloaded the latest version of this build, did a clean install, and while watching live tv, the deinterlace option is greyed out. Has anyone any idea if there is a workaround to get deinterlacing work? (Libreelec is installed on a NUC8i3BEK)

Disable "Allow using DRM PRIME decoder" in Player settings.

smp Please is there really no way to change that output from DP to HDMI 4K @ 60 as I described in this post?
I really have no idea why available modes are limited to 1080 for HDMI. Could be a driver or video bios table (VBT) issue. Try to update to the latest bios.
Also post kodi.log:
paste /storage/.kodi/temp/kodi.log
Bios is definitely up to date. Through Windows 10, the HDMI output is in the order of 4K @ 60.

Thank you
In both logs I see that it is connected to a Marantz AVR.
Can you connect it directly to the TV, reboot, and post kodi.log?

Directly TV
Well, I'm out of ideas
