So do Intel just support 4:2:0, 4:4:4 and RGB output?

If so then 4:2:0 is the only format that will support 2160p50/60 with >8-bit for HDR

What do you think about 4:2:0 12-bit vs. RGB 8-bit with dithering?

GBM version of Kodi (which is used in HDR builds) does not support dithering due to the lack of OpenGL. However, a hardware dithering can be enabled for 8-bit modes in Intel driver.

By default the Intel driver does not dither and I see some banding with some of my sample videos @ 2160p60 8-bit output.

With dithering enabled those videos look much better, much less or no visible banding.

I suspect that a .tar file will not do him any good.

Stable 9.2.3 will not work on his NUC 10 with Comet Lake-U CPU. Needs a newer Linux kernel.

I tried DVBSky s960 on H3 board, it worked ok.

I had the same as before - no video.

Does it play non-HDR video (with drmprime hw decoder enabled)?

New Linux patches just showed up which add HDR support for Parade Technologies LSPCON controller as well as MCA LSPCON controller. If anyone wanna try them I can build an image.

Upd: here's a new image with those patches included.

majofi has it working so it does work on one gen of devices at least

That's what I said. I don't expect it to work on anything except Gemini Lake. J5005 is Gemini Lake.

Quote from Nekromantik

does it only work on Gemini Lake?

I don't expect HDR to work on anything else yet.

Only thing is that Deinterlace is gone

Kwiboo said that he will implement ffmpeg deinterlace vaapi filters in drmprime at some point.

You can build your own image with the driver included.

That's for AU chip...

but how can I build/install it for LE?

RTL8821CU: add package by AlexanderAmelkin · Pull Request #4381 · LibreELEC/LibreELEC.tv · GitHub

AFAIK Braswell does not have a proper fixed function decoder for HEVC 10-bit. It use a GPU-assisted "hybrid" decode.

Continuity errors are most likely due to a weak hardware of your tvh server (pi3).

In my last build I forgot to include this patch, so it did not switch to BT.2020 color gamut when playing HDR video.

I uploaded a fixed build. Kodi is also updated to a current master.

Post the mediainfo of the file which cause high cpu usage during playback.

AMD GPU Radeon™ Vega 3 is integrated only in APUs Ryzen family Series, (core Raven Ridge or Picasso)

That is not correct.

Do you think all will match OK ?

Yes.

Question: Is the Cooling fan already in the AMD CPU / GPU package ? (Like on Intel CPU package)

If the CPU is a retail version in a box it will include a cooler.

LibreELEC : Last Generic Version will be OK ?

Yes.

SSD Sata 6GB/s: What size do you think useful to install LibreELEC ? (alone)

I use a 16Gb SSD with no issues.

HDR is not going to work on this anytime soon.

Read the last few pages of this thread.

The file plays fine on my Intel J4105 and AMD 200GE boxes.

That Zotac is a waste of money. I can suggest this for a nice LibreELEC box:

ASRock J4105B-ITX Intel Celeron Quad-Core Processor J4105 (up to 2.5 GHz) Mini ITX Motherboard / CPU Combo - Newegg.com (I use it in my main LibreELEC box).

MX500 Industrial Fanless Mini-ITX Case w/ 80W DC-DC Power Board & 60W AC Adapter - Newegg.com

Crucial 4GB Single DDR4 2400 (PC4 19200) 260-Pin SODIMM Memory - CT4G4SFS824A - Newegg.com

I am interested by a Zotac ZBOX MI 660 Nano

Is it going to be a LibreELEC-only box? There are better and cheaper options.

1. Anything with Intel Gemini Lake SoC (e.g. Celeron J4105).

2. AMD APU with Vega graphics (e.g. Athlon 200GE). Asrock DeskMini A300 should be a good platform for that.
