Im getting very mixed messages across the internet if the u9-h plays dolby vision. for some it doesnt do it at all, for some only demo's. for some movies and demo's....
User skynet @ Minix Forum:
"I just tested this 4K Dolby Vision HDR : LG: Dolby Vision UHD 4K Demo | 4K Media
I can play it but not in HDR mode and it stutters a lit bit.
All others BT2020 10 bits HDR work fine."
Dolby Vision doesn't work yet unless you have an Oppo UHD Jailbroken Player.
Then someone else comes and says:
"Libre ELEC on u9-h and shield supports dolby vision via raw BluRay files... No remux support yet because of how mkvs work."
I say that you have 2 dolby vision streams, and that I heared that the one that is able to playback actual UHD Dolby Vision is missing, just the Dolby Vision Stream to Playback Dolby Vision Streams.
Correct... Type it into Google and check the forums on Libre ELEC... It's far superior to Android version of kodi. I run it on my neo u1 and u9-h....
Go. Directly to the Libre forums not the minix forums... I run both 17.6 and kodi 18 that's based on Libre 9
So he's saying that it has the same functionallity for dolby vision as the Oppo Player..
Someone on kodi forum:
"f this question is about the Minix U9-H, there is no Dolby Vision support at all. The box doesn't even have HDCP 2.2 enabled which is required for Netflix 4K. You have to use a patched Netflix apk to get 720p streaming with the official Android firmware. With Android TV firmware, you can get 1080p streaming.
What you see on that website is copy & paste of Amlogic specifications. Amlogic has designed the SoC to support HDR10, HLG & Dolby Vision. I have yet to see one box with this SoC that supports Dolby Vision. I have checked another S912 box that shows Dolby Vision options in its firmware and even on that, Dolby Vision wasn't working."
"Yep - media players/streamers will have DV support in their specs to support streaming services like Netflix etc. who offer DV content. They won't offer it for playing UHD HDR Blu-ray rips with DV content."
"Yep - though beware, as I mentioned, there are two different standards now for carrying DV over HDMI - so you could end up with a DV source that isn't compatible with your DV display.."
"UHD DV Blu-ray uses a very different DV profile to streaming services that use DV. Even if you do find a box that runs Kodi and has DV support you can't expect it to play UHD DV rips, as it is likely to only support DV profiles used by stereaming services.. (DV are unlikely to licence a product to play content that can only have been sourced through ripping...)
There's another thing to consider with DV too - as changes appear to be afoot.
We now also appear to have a fork in how Dolby Vision UHD Blu-ray players (and other devices?) work over HDMI too...
Sony's recent DV upgrade to their UHD TVs seems to have surprised a lot of people by sending the dynamic HDR DV metadata over HDMI using the new dynamic metadata signalling introduced in HDMI 2.1 - that also allows for HDR10+? (I'm guessing they have retrospectively added it to HDMI 2.0b compatible TVs?).
Other DV compatible TVs require the TV to extract the DV metadata embedded in the video stream itself (where it is tunnelled I believe?).
So now there are two different ways of carrying a DV signal over HDMI it seems. (Suggestion are that DV being added to non-DV specific hardware may be the reason between the differences)
This means that DV compatible UHD Blu-ray players will need to be able to output DV over HDMI in two different ways to be compatible with both flavours of DV TVs, and will need to offer the new dynamic metadata carried in the HDMI standard via a firmware upgrade. Sony's forthcoming X700 UHD Bu-ray player will no doubt support their version of DV signalling, and Oppo have announced they will too. Who knows what media player manufacturers will do..."
"You can trust my finding or test it out yourself. I also have to say that it is highly unlikely that any device that isn't an Ultra HD Blur-ray player will support Dolby Vision profile 7 (the one used in retail Ultra HD Blu-rays). Profile 7 support on devices that are not Blu-rays indirectly means support of ripping Ultra HD Blu-rays."
So does it support playback of Bluray UHD Dolby Vision or not... I ordered the miniX u9-h few days ago and it is coming within 2 weeks.
