CoreELEC on Vontar X4 S905X4 - no HDR10+?

Help & Support Hardware
1

I installed to an sd card and booted, everything seems to be working except there is no where in the menus that mention metadata, no where to disable DV and enable HDR10+. And when I play a file with HDR10+, on my Samsung tv it only shows up as “HDR”, not even “HDR10” or “HDR10+” which I know it will do with the right video.

In Kodi on my Nvidia Shield Pro, I could disable DV as metadata, unfortunately that device does not support HDR10+.

No log, no problem.
Original DV media only have HDR10 as fallback, not HDR10+.

3

My “Back to the Future” has HDR10+ as a fallback.

4

Yes, because it’s not a official release. It’s a private remux.

5

How do I provide a log? I’ve tried with several files that explicitly have HDR10+, also one test file specifically designed for testing out HDR10+ meta data.

This is on Vontar X4, edited the title.

I guess like this coreelec:debuglogs [CoreELEC Wiki]

I’ll do it tomorrow when I have time.

This is new for me because both formats are competitors and it’s strange to see it combined.

Anyway, it got confirmed long time ago it do work and HDR10+ is used when display does not support DV. But I guess the at least the player needs to support DV to be able to use correct fallback.

In this case it’s not a fallback. They are videos that do not have DV at all, only HDR10+ which I guess could fall back to HDR10 on displays that do not support HDR10+. But this display does, Samsung S90D.

Short media sample?

The first file is found here 1 minute HDR10+ system test - FF Pictures GmbH | Florian Friedrich

I guess I could create a sample of the second somehow. But as you can see, mediainfo confirms it to have HDR10+.

If you have a HDR10+ file you would like me to test, I’ll be happy to. Thanks in advance :blush:

I am sorry to have wasted your time :flushed:

Since my receiver, NAD T758 V3i, had no problem in passing through Dolby Vision to my previously owned LG C1, I assumed that it would also be agnostic and transparent with regards to HDR10+. Unfortunately, that’s not the case. When I connect directly to tv bypassing the receiver, HDR10+ works.

I bought the Vontar to be an upgrade over Nvidia Shield with regards to HDR10+. Since my current tv is a Samsung S90D that does not support Dolby Vision. Now I will have to buy a new receiver as well.

Fortunately, S90D looks great in its basic HDR mode, when I compare with the HDR10+ bypassing the receiver, the difference is not very important.

No need for a new receiver if it does all you want, beside HDR10+ passthrough. Get a decent HDMI splitter and than your issue should be solved.

My Yamaha receiver does NOT support HDR 10+ either. I connect my box directly to the TV’s input and use eARC to passthrough the audio… With the advent of eARC and TV’s that support all of the audio codecs for passthrough, connecting to the TV is the way to go.

In the old days, you had to connect to the AVR to get the advanced audio codecs from the media.
