In the meantime I have also managed to integrate EAC3 incl. Atmos into an SL DV MP4.
Here is a small example:

how are you creating single layer DV files? afaik there is no legit method to convert dual layer DV into single layer, since DVDFab produces fake DV. any official word from Plex devs on how we are actually supposed to use the dolby vision support? just triggering the DV mode on tv is not enough, the content actually has to provide proper DV video, which we have no way of obtaining except a few demo LG videos.

I totally agree with you! Single-layer DV support on Plex is senseless since, indeed, we do not know whether DVDFab’s single-layer DV is actually DV.
That’s why I just started a feature request for supporting dual-layer Dolby Vision in MP4s. Please vote!

Everyone here in the thread should have an interest in Plex making Dual Layer Dolby Vision (in MP4s) playable on Shield 2019!
So please vote in TobyX’s request! (link over here)
!!! VOTE 4 REAL DOLBY VISION !!!

Is it not the case that Shield 2019 pro physically can’t play double layer DV files, even if software supported?
I have the option to play Double layer DV files on my LG TVs if I so choose.

Do you have any binding statements or links on the subject?
Yes, that’s possible - but only via USB - that’s not an option for me. My TV only has a 100mbit port and that is unfortunately not enough for high quality material. In addition, I have no AV and TV with eARC so that you have to do without HD sound.
There is no knowledge about that… there is only the assumption that it is logical because the Shield is basically designed for Streaming services.
However, we also expect that it does not matter if the Exoplayer can do dual-layer DV. In case of the Shield can only do single-layer it is highly likely that it is limited to its own services (eg the built-in media player). That certainly does not affect external software like Plex (what comes along with the Exoplayer).
Currently it (the Shield) can’t play dual-layer because Plex uses an older version.
Playing dual-layer simply means that the respective player takes the enhancement layer into account when playing the media. Currently Plex ignores it as it does not know what to do with it. Accordingly, I would expect that the assumption that the Shield can only do single-layer is limited to its own services.
Even if not… I would further expect that it is rather a licensing related limitation than a hardware based limitation.
what we need is confirmation that in fact native exoplayer can play dual layer DV on shield pro 2019, outside of plex.
that would probably require someone build exoplayer from source, create APK, sideload to shield, then attempt to play a suitable dual layer file (locally or remote).
unless there is already such DL/DV capable exoplayer apk available.
if exoplayer alone cannot be confirmed to play DL/DV, then that would likely hinder any chance of plex incorporating such changes…
hello, i thought i might join in because i’m very intrested in figuring DV out.
So far i have found out that apparantly plex (tested shield TV pro 2019) is able to play single layer DV. these files where converted using a software called “dvdfab” but atm rumor has it,that even though dvdfab has the capability to create both dual and single layer dolby vision,the single layer is apparantly a fake,and theirs a issue apparantly with high fps movies.
As for exoplayer,i think from my POV the issue won’t be to create a mediaplayer,but in fact to get licencing agreements etc. to use Dolby Vision, I don’t understand why plex installed on my TV allows for dual layer,while plex on my 2019 shield does not same issue for chromecast ultra’s, i think its a licence issue but i’m not sure. i have written down a lot of notes
this was my test batch for today:
Exactly, Plex supports Dual Layer In capable TVs and there is no reason why they wouldn’t on the Shield.
I believe this question is more suited for the nvidia forums, in my mind, as a shield owner since day one in 2015 I have read many threads that the shield video decoder can not overlay 2 streams at the same time, that is why MVC was never supported either officially or unofficially, like I said I think this is a discussion for the Nvidia forums, I do think it is a mute point though.
P.s. there are no problems with DVDfab single layer DV files at 60fps, anybody having problems should check their settings on Shield and tv as well as their signal path.
Remember the shield doesn’t default to 60fps playback, refresh rate app is your friend.
Please read my feature request post.
Importantly:
1. DVDFab’s so-called single-layer DV seems to be not real DV… so be careful when being satisfied with it 
2. Yes. I would agree that the problem may be more Nvidia sided. However, as I also pointed out: the Exoplayer could play it and then Plex would not rely on the Shield’s internal player what could be the key… and that’s why Plex is able to play dual-layer DV on some TVs. It uses another player
3. Even if not, it could also be a licensing issue… and then Plex or Nvidia would have to found out how to implement it. (I cannot imagine that there is a built in hardware limitation on the Shield… especially external software like Plex what comes along with such a license should be able to play dual-layer DV even if the Shield itself doesn’t).
i got myself a copy of gemini man today,i’ll be testing it today, i also downloaded the sample files took a while since they use google drive,kinda stupid tbh,and i’ll make a new sheet with records of those.
Hi, I’ve got a problem with the above…
DVDfab single layer may not be ‘real’ DV so be careful about being satisfied with it.
What a strange statement? If you are satisfied with it what does it matter whether it is real or not?

First short tests show me that the DVDFab SL DV looks exactly like DL. In principle, everyone can check this themselves, even with a bad camera like mine. Find a spot from the video and make the comparison …
For example, I looked for the spot on the Dolby Vision demo disc where the DV black is demonstrated. You can see that the point is much too bright with HDR10 and the screen is not darkened as with DV. With DV, the display is off except for the small area. So the black demo doesn’t really work with HDR10. You can see the difference with the eye and the camera.
HDR10 vs. DVDFab SL PF5 vs. DL PF7
In my opinion you can see there that the metadata for HDR10 is “static” because the brightness has been completely set for the video and the spot is too bright.
The TV is on the DV standard picture profile without any changes. The same with the HDR mode … standard without changes. Local dimming is set to Medium in the standard profiles.
I would be happy if you would also make such comparisons. @TobyX and I at least want to know that. But currently it looks like DVDFab has found a way. I don’t care if it’s “real” or “fake”.
@KCX many thanks for your efforts.
I’m oing to present some tests in the next days. I need some equipment for that… I will test some very dark scenes and scenes with different coloration.
When I can confirm @KCX tests, we could than discuss whether my recent feature request is still necessary. @crazydave80 pointed at some very serious things that may make it impossible to get dual-layer DV support in Plex (e.g. for the Shield).

I found a Dolby Demo single layer video that is not played by plex. The competitor with E can do that. What is the difference to other Pofil 5 videos? This video appears to be a real DV profile 5 and contains the full color range as specified by Dolby.
MediaInfo:
colour_range : Full
Video Link:
https://d3rlna7iyyu8wu.cloudfront.net/DolbyVision_Atmos/mp4/iOS_P5_GlassBlowing2_3840x2160%4059.94fps_15200kbps.mp4
(right click and save target for download)
HDR10 and the self-made single layers only have the limited color space:
colour_range : Limited
Here is the preview picture that my Plex Server creates.
However, the same applies to the competitor:
But that can also be due to my hardware, because I cannot play it directly on the server, no matter with which program or player. Hence the wrong colors?
But the fact is, the Shield is able to play this true DV Profile 5 video, but unfortunately not Plex.
@TobyX @DaMacFunkin @TeknoJunky and others… can you also test it with plex to confirm me? Thank you very much 
Hopefully at the weekend
