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.

that pic you posted was of what movie?

I think it's safe to say that it will work, Gemini Lake SoC = native HDMI 2.0, no LSPCON nonsense.
But before you buy the hardware you should understand that those LE images are very early and Kodi's DRMPRIME hw acceleration is not yet ready for everyday use. We may actually see better hardware (like Intel Elkhart Lake) before we see a stable LE image with HDR.

There is nothing new as far as HDR is concerned, only updated to a current Kodi master.
-
Does the issue occur with current Kodi master (v19)?
-
Great - so the industry standard for video production and post-production (4:2:2) - and the standard for connectivity in that area - is the one format that isn't supported...
They actually planned to support 4:2:2 as seen in this old patch but then it was dropped for some reason.
I tried to enable 4:2:2 support in driver but it didn't work, I guess I missed something.
-
It's not gonna work. Kodi will not run on that.
-
Hope this will help
Necroposting is usually not very helpful.

So do Intel just support 4:2:0, 4:4:4 and RGB output?
Yes.
If so then 4:2:0 is the only format that will support 2160p50/60 with >8-bit for HDR
Yes. but the driver default to RGB 8-bit. A driver hack is required in order to switch to 2160p50/60 4:2:0 12-bit.
AMD behave a bit different - no 4:2:2 support either but the driver default to 4:2:0 12-bit for 2160p50/60 modes.
-
The changes between 9.2.0 and 9.2.2 are kinda minor, kernel is the same (5.1.16). It doesn't seem likely that 9.2.1/9.2.2 would introduce those kind of issues.
-
I never has this issue before the latest update,
What is the last version of LE that does not have this issue?
-
Since this thread mainly focusses on older kernels I thought it was already out of the window @4.19.36.
Yes, that issue that was introduced in kernel 4.9 was fixed a long time ago.
In my experience Pi3 can barely handle 1 USB tuner, so I'm not surprised that Pi2 can't handle 2. I'm not sure this is fixable by software.
-
I still suffer from this when I enable both my USB tuners
Did it work without errors with older kernels (< 4.9)?
-
That's not correct, if by Deep Color you mean >8-bit bit depth. In fact it's quite the opposite.
I thought that was clarified back in February, not sure why you have to bring that up again.
4:2:2 is the only >8 bit format supported for all 2160p frame rates
4:2:2 is also irrelevant for any Intel hardware, not supported by the driver.
-
This is not configurable from userspace. If the display's EDID report YCbCr 4:4:4 support - AMD driver will use that instead of RGB. If for whatever reason you want to force RGB then make changes to the AMDGPU source code or use a custom EDID.
