Greetings to you all. I would like to ask what it looks like now playing with Dolby Vision movies in mkv in Zidoo z9x. Does FEL and MEL play it? I have a Shield for 2019 and I'm considering buying a Zidoo z9x if it pays off. SHIELD plays just fine FEL and MEL. I read that the Zidoo z9x has better colors. Thank you for your help.

So, you guys saying that DV on MKV on Plex/Shield is faulty.. will it ever be fixed in a possible update no matter how long it takes, or are we doomed?

As far as I know, FEL titles will never be played to their full capacity on the Shield, because it's simply a hardware limitation. MEL titles on the other hand and the color issues that exist with them, nvidia is still working on it, but since DV rips from disks are not really officially supported, only time will tell if and when that gets sorted out.

I do have a Sony UHD BD player that has Dolby Vision, particularly the 700 something, but with the new TV I legit do not have the space for it, so I can not hook it up in any form.

But even if it was possible, I do prefer the much easier, faster, click and play part of streaming instead of putting disc (remember in the Sony Blu rays, you have to manually switch on and off DV everytime you play a DV disc!)..

My TV can play MP4, TS, M2TS DolbyVision files via Default player and MKV DolbyVision remuxes via Modified Kodi (32-bit version)\
Any idea which format is best for accurate color and quality?

Yeah, a similar dilemma that I'm sure a lot of people faces: the ease and convenience of the Shield+Plex, or the picture accuracy of another device.

Eventually you might be able to get on the fly conversion from profile 7 to profile 8.1, at least with Kodi.
Then all files would be compatible with most devices at playback.
I don't believe streaming devices will ever get full support for profile 7 FEL.

I've already patched my Kodi to fix the DoVi/HDR10+ issue with the Firestick, so it's not that hard.
Just takes someone to do the work, basically just porting an RPU parser to C++.
Too bad yusesope hasn't shared their code, otherwise we'd have it already.

Unfortunately true. I don't see any streaming devices putting in the extra work to be able to process FEL simply because no such content exists from streaming services. Besides, even if they wanted to, Dolby may not grant them the necessary licenses for fear of piracy. Best hope may be a smart blu-ray player that can run Plex/Kodi. The xbox series x could've been the ideal device, but sadly it has a pretty gimped bluray player with regards to DV.

What was the issue that needed patching?

The Firestick Dolby Vision decoder panics and renders a black screen when it encounters a file that contains both Dolby Vision and HDR10+ metadata.
The source of the --skip-hdr10plus switch :)

I basically implemented the same behavior on the fly before the data gets sent to the decoder.

So oled tvs' internal media player and the oppo 203 are still the best ways to watch these DV remuxes?

But TV internal players aren't the best for playback, they lack chapters, may lack capacity for some audios (LG CX for example lacks DTS support).. lacks PGS support.. is it really worth it?

Your right, it probably isn’t worth the hassle, I have gone back to ripping FEL titles as Movie only ISO and watching on the Chinoppo, I upgraded my server with an extra 24tb of the Christmas break so I’ve got space to play with for a while.
Do love the convenience of Kodi / Plex/ HT4 though ☹️

I wonder is possbile to force non-dv video to play as dv via kodi on Shield TV?
It would help to better understand "red push" cause on Shield.
Since p7 and p8 are affected (both in TV-led and Player-led modes) and p5 is not there is only logical conclusion that something wrong with YCbCr processing on Shield's DV decoder. P5 is IPT
To prove it we should play plain HDR10 or SDR video via DV decoder.
But there is not possible for user to force DV output on Shield for non-dv video.

I'm out of the loop. Kodi can pay DV content now? Is this only for mp4s or mkvs as well?

Also if you or anyone else could answer this: assuming playback of DV content in remuxes improves in the near future, will it make any differences whether the TV supports TV led DV vs player led DV? I'm debating between a sony x950h (player led) and x900h (TV led-what I currently have but considering switching due to better PQ/higher peak brightness in the 950h)
