Hi, sorry I haven't been clear: I have not a shild tv pro, I asked in a few forums about dolby vision media players and I have asked about zidoo z9x or nvidia shield tv pro recently and some guys told me z9x and nvidia shield tv pro can't reprodure completely Dolby Vision dual track.
I have not detailed links to link here, I can give you this and maybe you can go deeply with some brower serches...

I try to sintethyze: I have heard nvidia shield tv pro can't reproduce completely dolby vision dual tracks from uhd bd because of some limitations...

I'm italian and I have a little trouble to explain clearly about this techical stuff in english, sorry... the main words you coul search are " FEL full enanchment layer" or (BL+EL+RPU) ... sorry but I just wanted to try to help you.

What you've researched is correct, neither the zidoo or shield can fully reproduce dual layer DV if it's an FEL title. They lack the secondary video decoder needed to decode the enhancement layer.

ok thanks.... Oppo or Oppo clones apart do you know which device can reproduce full dual layer DV?
I know about Plex media server for LG tvs before CX...unfortunately I have a CX and so I can't reproduce it

These are the results I'm getting on Nvidia shield Pro:

On plex:

.ts single track dual layer: dolby vision and atmos (no pgs subtitles working AFAIK)

.mkv: dolby vision and atmos ( no pgs subtitles working)

I use MKV on Plex on my 2019 Shield Pro and it works well, but I sometimes find it takes 2-5 attempts to start the film before DV triggers and not HDR. Has that been your experience?

I also find that it takes a little longer to start the film if it's DV - it sits at the spinner for a few seconds. HDR films are pretty much instantaneous.

Hey! Yes these files infrequently maybe load in HDR instead where I have to load them again to make them into Dolby vision. I would say mine take a couple seconds but I don’t really mind it. I just point it on my internet connection

Anybody knows where is Yusesope?
Almost one year he does not show in this forum.

In conclusion, I have no idea what common file to use to convert my dolby vision movies to. Ideally, I want them to be .mkv as it's just convenient but unfortunately the oppo 203 can't play it in dolby vision. Any ideas? thanks:)

Recheck Plex settings (both server and client)
Pgs subtitles works just fine

If you want to use both oppo and shield, convert to *ts STDL

Still MakeMKV P7 backups are lossless and could be converted to anything else, like DTDL ts or mp4

Hello! Thankyou for your reply.

I'm a little confused by these terms sorry I might require some clarification. Does Single Layer Dual Track mean 2 different files for the Base layer and a different file for the dolby vision(EL+RPU?)
and does STDL mean it's all combined? (BL+EL+RPU)

If that's the case, then .ts SLDT works in dolby vision and atmos on oppo, but doesn't play dolby vision on shield.

The 2 which are the best are .m2ts STDL and .ts STDL but .ts STDL is hit and miss on oppo.

I cleared cache for plex on the shield and the subtitles started working! Thankyou tho!

"single layer mp4s from DVDFab, however, remain quite questionable at best.."

I think Grencola mean DVDfabs single layer conversion is questionable, which I agree.
Some conversion work flawless on my C7 and LG UHD BLuray(USB), however films like Transformers 1-4 just mess up, red & green flashes and if I use the UHD player it looks like i've dropped my screen with vertical coloured lines tearing up the screen.

I have the same problem with bumblebee on the LG which is essentially a transformers film but it plays fine on the Shield Pto 2019.

I have the exact same problem too!
On my oppo coming up with vertical lines.
On my shield pro, it’s working.
Apologies for bringing up an old topic but was trying to find answers in what I was doing wrong! Also using DVDfab making a dvhe05.06.
Not sure if I was hallucinating or not but after a restart of the player earlier today, I played the file again and it was normal and thought the problem was fixed and didn’t think anything of it. Now I have it again and no solutions! Grrr.


https://imgur.com/a/gSowr2D

EDIT: I have fixed the solution! ( reminder this is a .mp4 dvhe05.06 )

100% working fix for the oppo/chinoppo ( maybe other UHD players too)

Switch off your OPPO. Play any dolby vision video which has an enhanced layer on it. ( I tried John Wick, Gemini man, and .mp4 Dual Track Dual layer of John Wick all working). When the dolby vision pops up in the beginning of the movie, close the movie and play your DVDfab dvhe05.06 .mp4!! )

Vertical lines vanished:D

In my opinion looks identical to the disc too:)

Sorry, typo.

Hi guys, a little help, mi Lg B6 just died so im looking for a new tv, of couse it must be oled, so wich tv is the best for pop up like quality for dolby vision mp4 movies? also for hdr theres any down side?
i have money for a Lg C1, anything in that range price or less would be nice.

I read that the c1 is even darker for dolby vision than the cx and the cx is already really dark so im kinda scared to go for the c1, no reviews with dolby vision or anything so it would be a blind choice for me

Any help would be really nice.

pd:i was using the sony x700 to reproduce the dv movies cause the b6 had memory issues, and i have a jbl 5.1 soundbar.

pretty sure the lg oleds haven't gotten worse in terms of PQ with each generation. If you're really worried about it and your budget can stretch it, go for the g1 evo or one of the sony master series oleds.

Can someone please help me? I've tried for 3 days now, my mp4muxer is giving me 0 bytes file
I'm trying to run mp4muxer on parallels on mac. I have no tech knowledge whatsoever. After some googling I've managed to figure out what to do when unc paths are not supported.

This is originally what it says on cmd when I ran it in the directory for mp4muxer

C:\Windows>
C:\Windows>mp4muxer --dv-profile 7 --input-file BL.hevc --input-file EL.hevc --input-file audio.ac3 --media-lang eng --output-file testmp4john.mp4
'mp4muxer' is not recognized as an internal or external command,
operable program or batch file.

C:\Windows>



Then I thought maybe it can't recognise the file cus it's in parallels. So I made a .bat file with PUSHD and POPD and clicked it.

'\\Mac\Home\Desktop\dlb_mp4base-master\dlb_mp4base-master\bin'
CMD.EXE was started with the above path as the current directory.
UNC paths are not supported. Defaulting to Windows directory.

C:\Windows>PUSHD \\Mac\Home\Desktop\dlb_mp4base-master\dlb_mp4base-master\bin

I:\Desktop\dlb_mp4base-master\dlb_mp4base-master\bin>mp4muxer --dv-profile 7 --input-file BL.hevc --input-file EL.hevc --input-file audio.ac3 --media-lang eng --output-file testmp4john.mp4

Nothing shows up in cmd and I get a .mp4 in my folder which is 0kb. Anybody got an idea of what's going on and how to fix it please? thanks.

EDIT: I also managed to get yusesope's tool working completely on macbook with parallels using PUSHD and POPD so I don't know why this isn't working

[narcospablo123]

I just tried it on windows boot camp where it’s identical to a windows machine. I still can’t get it to work??! I just end up with a 1kb file. What gives?

EDIT: do i have to wait for like an hour for the file to complete? it's been 20mins and it's still on 0kb

EDIT: fixed:D you just have to wait like an hour and it does it's job and shows up on folder. Time to uninstall bootcamp. Hope that code above helps anyone trying to do this on a mac, works for both mp4 muxer and yusesope's tool using PUSHD and POPD method

One of the reputable members of this website and also avforum for the m9702 page states the following:

"dolby vision profile 7 it's ONLY support by TV, BD player and av reciver (SDK license).
Other device support ONLY LLDV = profile 05 = netflix ecc ...; DV mkv it's notting more to a "experiment" conversion 07-> 05 with many many problem"

does this basically mean in simple english that playing profile 7s on a shield in basically a waste of time because the quality of the image will be like a dolby vision 5 profile? ( without the EL layer?)

he also mentioned tv, so can LG CX/C9s play profile 7s without issues? what formats can they do this in? thanks

[shawnc22]

Anybody here have the Lg C1 and if so, theres any playback issue with dolby vision mp4 movies with the native tv app just using a external hard drive?.
Dolby vision dual layer FEL?
Tnx.

As far as I know, LG Oleds beyond the generation of the 9 series (X and 1) are no longer capable of playing FEL files from its internal apps. The 9 series can still play dual layer dual track mp4's. There is no DV mkv support on the TV internal players.

As for the other statement, no, DV MKV is not an experiment. There is no profile 7 to profile 5 conversion happening. MKV is merely a container and no data is lost or converted when a DV disk is ripped to MKV using MakeMKV. Whether or not a specific piece of hardware is capable of playing back a DV MKV to its full capacity is another question. LLDV is not related to profiles; LLDV is a variation of how DV is transported from your source (BD Player, streaming box, etc) to the sink (TV). If your TV does not support decoding of a full DV signal (mostly early Sony Oleds), then your source has the responsibility of doing the tone mapping and sending the resulting signal to the TV (LLDV). This is inferior than just letting your TV doing the decoding and its own tone mapping, but regardless, the transport method of DV has nothing to do with profiles.

Most streaming boxes on the market that are capable of playing DV MKVs (Shield, Zidoos, Dunes) can only in reality play MEL titles. These boxes lack the secondary video decoder needed to fully process an FEL title. When these players encounter an FEL title, they will simply ignore the EL and just apply the RPU dynamic metadata to the BL. Whether this is a "waste of time" is up to the user. RPU applied to just the BL is still superior to normal HDR10 and for certain titles, even the FEL doesn't really contain that much image data. There are reports of a few streamers that are capable of fully processing FEL titles (the new google tv chromecast and some chinese Amlogic S922XJ-based boxes), but their limitations have been well documented elsewhere in this thread.
