Dolby Vision now possible through MP4 Mux.

[userr]

Can anyone enlighten me why the following happens for me?

Sony AG9 Oled TV and Nvidia shield 2019

When playing profile7 mkv files from makemkv, that also contain TrueHD audio, i only get HDR
If i change audiotrack to normal ac3 track, i get dolby vision

Im using the TV builtin speakers to eliminate any compability issues with AVR etc.

Anyone can help?

If you're playing on the Plex app, you need to be direct playing both video and audio. If TrueHD has to be transcoded, the video changes to direct streaming which does not trigger Dolby Vision.

Thank you, how do i make sure its direct playing and not "direct streaming"?

By connecting the Shield to a device that can handle TrueHD, so it has to be your AVR and not the TV. If your AVR cannot handle TrueHD, then unfortunately you're out of luck.

So i would need a capable AVR and use eARC from TV and it should work?

No just get a capable AVR and connect it straight to the AVR.

I’m trying to make a dual track mp4 file of watchmen with the old version of mp4muxer which worked fine for many movies (at least 20). The issue I’m having with Watchmen is that mp4muxer stops immediately without any error message, it juste creates a 0mb mp4 file and stops instantly.

I really think I had this problem, is it because of all the branches?
I think I ripped the playlist with TS muxer first then used the output from TS muxer.

Hi Yusesope.

It would seem that MKV FEL converted to 8.1 with Beta 004 triggers Dolby Vision on the new Zidoo products. MKV FEL to 8.1 with Gamma doesn't trigger Dolby Vision on the new ZIdoo products.

Is there a reason for this, what is the difference?

Thank you.

I have no idea. Owners of other devices do not complain about this problem. When I have time and you are available maybe we could do some tests together to understand where the problem lies.

But first I have to extend GAMMA support to Linux too, fix the creation of the mp4 DTDL files, add chapter support ...
You need to have a bit of patience...

Hi Yusesope,

A couple of People on the Zidoo forum are claiming that if you run the patched 8.1 file your software creates through Makemkv 1.1.53 it will then trigger DV on the new Zidoo products.

I'm going to try it now, do you need samples?

[MastaG]

So what about the LG OLED series 6 up to the latest CX series?
Will the Gamma MKV's trigger DV on all of them using profile 7? (either MEL of FEL)

Seems like Plex is getting somewhere with nvidia:

https://forums.plex.tv/t/newest-beta-do ... 640693/232

We’ve been working with NVIDIA and have found the cause of a crash which would cause Dolby Vision files to fail to direct play and fallback to a direct stream which only supports HDR10. The fix will be released in the next SHIELD OS update (8.2.1).

But they don’t seem to be aware of the colour issues

https://forums.plex.tv/t/newest-beta-do ... 640693/234

Do you have a sample for the colour problem? I’ve tried the batch I have (mostly from this thread) and the files all seem to be playing with the correct colours on 8.2.1 of the SHIELD OS.

Slightly off topic, but will the new Xbox series X and S playback these STDL DV MKVs? AFAIK, they support DV for streaming apps but not UHD disks. Just like many TVs and Firestick 4k DV implementation. I'm planning on getting the series S if they do support these files.

I honestly don't know because I used a mkv remux for this one that I demuxed. So did you get it to work in the end ?

Not as MKV as there's no updated built in player that reads the metadata. Just mp4 and TS.

Dr. Seuss' The Grinch (2018) - FEL DV
mkv on Shield TV Pro 19
Can't spot any "red push" issues.
Played nicely by the latest Plex

I really like it as HDR demo, so much colours

Doesn’t have natural skin tones or dead blue skies as it is animation, it is meant to be bright.

that was me DaMac

run m2ts thru gamaa ..resultant mkv shows as mel 8.06 but plays as hdr on zidoo z9x
run that mkv thru makemkv.53 and file still shows as mel 8.06 but now plays as Dolby vision and dolby atmos on the Zidoo
a file like Justice league then hits 3 min 44 sec and starts stuttering and audio goes out of synch by 2 sec lag

i posted a fix of sorts to that thou

i ran the mkv thru mkvtoolnix...cropped it at 01:55:00 (just into credits)
File then ran to almost an hour before it finally got bad stuttering and audio 2 sec lag
checking that with other files atm
Alita mel7 same stutter audio lag after 5 mins on both versions

gonna try 5th element now ,once i finish gamma



So 5th element didnt help
straight gamma mkv with 8.1 played as hdr on zidoo
makemkv made it play as dv/da but stutter after few mins
mkvtoolnix crops front first back next both had same stutter issues after few mins

shame cos looked like i was on to something when JL improved so much

try some more things i guess
