Intel true 10bits/HEVC/HDR support... ?

is there a list of hardware somewhere that it is confirmed to work with please?

Below is my experience, links contain info of cpu,gpu etc

I have successfully tried LibreELEC-Generic.x86_64-10.0-devel-20210524004323-f9d2c33-INTELGFX.img on:

2 x Intel® NUC 11 Performance kit - NUC11PAKi5 Product Specifications

1 x Intel® NUC Kit NUC7PJYH Product Specifications

and unsuccessfully on:

1 x Intel® NUC 8 Mainstream-G mini PC (NUC8i5INH) Product Specifications (has amd radeon)

LibreELEC-Generic.x86_64-10.0-devel-20210601032257-86a07cd-AMDGFX.img

unsuccessfully on:

1 x Intel® NUC 8 Mainstream-G mini PC (NUC8i5INH) Product Specifications (has amd radeon)

black screen for both images even after fiddling with drmprime options

Also works well on MSI Cubi N 8GL with Gemini Lake Pentium Silver N5000 CPU...

If you can find one cheap, it's an elegant platform and silent since passively cooled. The only downside is that 4k tops out at 30fps since it only supports HDMI 1.4 (a limitation set in the BIOS I assume)

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 read about this with other boards that should support HDMI 2 but don't and believe it's a BIOS limitation (possibly set to save compliance testing cost?). HDR does work well, however, and triggers the HDR status icon on my LG OLED TV.

There's a thread about HDMI compatibility and some systems not supporting 2.0 when they could here... HDMI 2.0/HDCP 2.2 motherboard verification - testers needed : htpc

Hi!

Just to add that HDR seems to be working on NUC7i3BNK, too.

I can't find xrandr anymore, though, and tvheadend 4.2 can't find libvdpau (I couldn't find it either):

"error while loading shared libraries: libvdpau.so.1: cannot open shared object file: No such file or directory"

any idea if this is something I can solve by e.g. installing something or is this a "feature" of the image?

Thanks a lot! Looks like it's working. Probably could have found it with a search, sorry...

I also did notice the same thing as porkchop999 (but with LG OLED):

I haven't been able to notice the green on my TV (Sony AH8). Although I can't get the tv to pickup full range. Kodi is set to full but the tv is picking up the signal as limited. If I force full on the TV if washes out the picture. Are you still forcing full range in your builds ?

The test video they screenshotted also looks the same for me. Dark areas looked a bit too crushed so I upped TVs brightness-setting in HDR-mode just a bit, but I'm wondering if that's normal or if there's something lost on the way.

My guess would be that GPU uses limited range and scales down the full range like: Kodi (full) -> GPU (limited) -> TV (limited), and maybe that's OK, but I'm really not sure since the setting in Kodi used to match the TV setting previously.

I tried the Asrock H570M-ITX and the new Intel i5-11600 processor, but there is probably no driver for the new GPU 750. Libreelec will run, in max. 1080p resolution, but nothing can be played. (black screen)

The official version 9.95.4 does not work.

Is there a chance it could work?

Thank you.

ahh asrock...never again

Anywhos, it's a very new cpu ymmv with SMPs build. He would know.

But! without going in to too much detail you could try adding:

echo "options i915 force_probe=4c8a" >> /etc/modprobe.d/i915-fingerscrossed.conf

and reboot to see if that works.

Okrúhly prsteň s kvetinovým vzorom.

Thanks for the tip.

I tried to send it via PuTTY ssh command line, but nothing happened after the restart.

I also created the folder etc/modprobe.d and in it "config i915-fingerscrossed.conf"

with line: options i915 force_probe = 4c8a

and no change.

When I turn off VAAPI hardware acceleration in the player, I get a 1080p image.

I use LibreELEC devel-20210601032257

Thank you.

The graphics drivers are build into the kernel and not loaded via modprobe.

Technically you have to add the parameter i915.force_probe=4c8a to the kernel command line in /flash/syslinux.cfg.

Thank you very much.

I downloaded syslinux.cfg to the text editor and added the line i915.force_probe = 4c8a, but I can't save or delete the modified syslinux.cfg.

It's probably write-protected.

How do I get there?

Well thank you.

I'm sorry, I'm doing this for the first time…:)

Where should it be located?

I have already made 10 attempts and nothing happened after the restart.

Thank you.

Add it to the APPEND line.

But by looking at Rocket Lake (RKL) discussion I doubt it has any effect.

I already had it at the end of the line because it seemed logical to me

And I read the discussion about rocket lake all around, but I don't understand anything.

Thanks

I like libreelec on intel platform for its speed. I use an asrock board with hdmi 2.0 and i3-9100.

But by introducing rocket lake, I wanted to finally try native hdmi 2.0 on the processor

Bottom line: Using Kodi with Rocketlake CPUs is broken atm due to problems with Intel media-driver.
