4K HDR10 - State of Play thread - important media player limitations.

Too many variables in the HDMI chain to even make an educated guess.
Simply do a .tar backup of your current CE setup and store that CE .tar backup on your PC.
Then do a -ng nightly .tar update and see what happens.

For HDR10+ to work everything needs to be HDR10+ compatible, including AVR's supporting HDR10+ Video passthrough. Which a LOT of ones do not.

Thanks for the advice regarding taking a backup first.

I'm not looking to get HDR10+ working correctly since I know my TV doesn't support it.  The closest evidence I can find so far is someone on the CoreELEC forums stating a nightly build from the end of September allowed HDR10 output from an HDR10+ file.  Looks like I'll be doing some testing soon.

I'm trying to get Kodi to properly play 4k HDR titles on my new Sony A9G. Thus far no matter what I try, my Sony A9G is not receiving HDR from Kodi (works fine on other apps like Netflix).

I've attached logs from my attempts if someone could please point me in the right direction. My understanding is that if the playback device supports HDR, Kodi should pass it through fine. I've tried both directly on my Sony's Android TV interface, as well as on an Amazon FireTV Stick 4k. I've also tried a mix of HEVC encodes and compressed x265 encodes with HDR.

Test directly on Sony (A9G) Android TV 9.0 Pie

Test on Amazon FireTV Stick 4k

Any advice would be greatly appreciated. If I should be posting elsewhere please let me know.

New Nvidia Experience update out which has a whole slew of fixes. One of them pertains to Dolby vision and frame rate matching.

I'm not familiar with the Sony A9G, but on my LG OLED C9, you have to manually turn on the HDR feature, for every HDMI input. It's off by default. Just a quick thought. 
Also, is Kodi directly plugged in to your TV or are you using an AVR? Is the AVR HDR compatible? Your HDMI cables that Kodi is using... how old are they? Are they High Speed HDMI cables?
The HDR file that you are trying to play in Kodi... is it really an HDR file and what kind? (HDR10, HDR10+, DV, etc.) It could be so many different things...
4GB ODROID N2 64GB eMMC, Asus i3 Chromebox 128GB, Nvidia Shield, Wetek Hub, AFTV
CoreELEC Nightly, LibreELEC 9.2, Kodi 18.5 
LG 65" OLED C9 and Onkyo TX-NR636 Atmos 7.2

I am moving Odroid N2 from a very convoluted HTPC setup that was capable of playing 4K HDR10 every now and then, wont say effortlessly.
I have high expectations from N2 after reading all the comments on this thread. The one thing I was not able to find in here was if anyone is using skins/interfaces with Kodi? I used to skin the hell out of my Kodi on my HTPC. I have brought a 128GB eMMc module, and was wondering if i can use the Aeon MQ 8 skin/interface? Also, is there any limitations with N2 if I am going to install Kodi add on plugin's? Does everything work just the way it should work on a windows based HTPC?

I received my Odroid N2. I have just completed the setup, and right after that, I fired up a 4K movie in HDR10 format. The movie started playing in HDR10, but after I stopped playing it, the HDR mode won't turn off to standard picture. Now not only the CoreElec UI, but even a standard non-4K movie is saturated, as the picture has not switched HDR off to regular standard mode.
What do i need to do?
Also another question, what resolution do you suggest I should keep in CoreElec? I have a 85" 4K TV and a 4K receiver.

Support for CoreELEC on the N2 should be asked for over on the CoreELEC forums
(it's very likely a TV / AVR setup issue - make sure Kodi Refresh Switching is enabled - Start/Stop - too)

Does the AMD Ryzen 5 3600 etc support 4k 10bit HEVC HDR decoding and smooth playback
or do I still need to buy a nvidia/amd gpu?

And what is the cheapest gpu recommended from nvidia/amd that can decode 4k 10bit HEVC HDR?

You should add the recommendation of the cheapest gpu model for nvidia and AMD on the front page..

You want the Nvidia GT 1030. It has better drivers for HDR10 video support than AMD and is cheap and capable.

so AMD Ryzen 5 3600 can't natively software decode 4k 10 bit hevc hdr with smooth playback?

Yes it can, but the resulting output can sometimes use the wrong color space (Rec.709) because of the buggy AMD video drivers. Nvidia is more reliable by comparison.
