Or maybe publish the patches involved so we can build it ourselves.

BT.2020 for Kodi 20

Channel switching GUI flicker fix

Does this happen only with 24p videos? Kodi has this "feature" - the audio of any 23.97/24p source is a bit delayed by default. To work around it this has to be added to advancedsettings.xml:

 <advancedsettings>
  <video>
    <latency>
      <delay>0</delay>
      <refresh>
        <min>23</min>
        <max>24</max>
        <delay>0</delay>
      </refresh>
    </latency>
</advancedsettings>

3B+ was released way before LE 9.2. No idea why it doesn't boot for you but it's not the firmware.

Is it not the Generic-legacy i should be using?!

Asus s1-at5nm10e has nvidia ion 2 GPU. Generic-legacy should work.

if I change I see dark hdr again.

What image did you try?

BT.2020 issue should now be fixed in the nightlies.

Intel HW decoding/encoding features list can be found here.

Quote from fab233

they say AV1 decode NO

That page is wrong. All Tiger Lake CPUs (including Celeron 6305) can decode AV1 in hardware.

Are there any similar boards with newer mobile CPUs (1135G7 or 1240P)?

https://www.aliexpress.us/item/3256805040832385.html (Celeron 6305)

I have a mini PC with Celeron 6305. It supports hardware AV1 decoding and the GPU is powerful enough to do a Lanczos3/Spline36 1080p-to-4K upscaling.

not booting (live) when TV edid is set to 2.0

Not booting at all or just no signal?

Quote from AGLyons

8bit signal

Try setting the "EDID" to "Expanded". If this does not work dump the projector's EDID and post it here.

BT.709 color space

Use my build for BT.2020

Quote from AGLyons

4k 10bit 24hz 4:2:2

4:2:2 is not supported by Intel. However, I seriously doubt that it is really required.

Quote from sjefsbamsemumsen

I cannot see that TV settings are relevant as the colours are correct when running Kodi for windows on 24hz or any other settings.

Intel GPU driver for Windows may behave differently, e.g. it can support YCbCr output, in Linux it only supports RGB. Your issue has something to do with incorrect handling by your display of RGB full / RGB limited at 24Hz. Most modern TVs have a user selectable quantization range for RGB and also the Auto setting.

I had this issue with J4105 board + 2018 Samsung 4K TV.

4K 50/60Hz mode should work with LE11 and HDMI UHD Color=off. It will be limited to 4:2:0 8-bit.

Try to disable "Input Signal Plus / HDMI UHD Color" in Samsung TV settings (General-->External Device Manager).

It is broken in 20.1 and master. Removing this part of the code fixes it:

Updated build with Kodi 20.1

- added BT.2020 patch

- Linux 6.2.5

- added a fix for DTS-HD detection in m2ts files

- added a fix for GUI flickering during TV channel switching

- Intel media-driver updated to 23.1.3

- Mesa updated to 23.0.0

LibreELEC-Generic.x86_64-11.0-devel-20230312065957-84d83d1.img.gz

The new build is based on "vanilla" Kodi. It is almost the same as official LE11 image. The old one was based on lrusak's HDR branch which isn't updated since April last year.
