Dolby Vision now possible through MP4 Mux.

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.

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.

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

Hi,
I feel your pain with the Zidoo Z9X Dolby Vison / Amos bug, but that isn't to be confused with getting the Gamma 8.1 to play, it is a seperate issue.

Why did you convert Justice League to 8.1, it is MEL and will play in profile 7 fine (IF the Atmos bug was fixed).

given an makemkv created dv mkv, can one turn it into a valid dv mp4? or is that not possible?

Technically, yes. You can demux the video track and then mux the raw stream into an MP4. However, you lose most of your options when it comes to the audio (mp4 does not support most high-end multi-channel audio formats) and you will lose chapter and attachment support.

Edit: Manually setting audio delay of around 170ms seems to fix the issue but this shouldn't be happening right?
Is there a solution for this? Or has this happened due to something I did wrong?

It's not your fault.
FFmpeg can rarely fail to perfectly sync my video with the audio in the chosen file.

I don't know how you solved it (there are so many ways), the easiest for me is to use the -itsoffset switch inside the second command.
-itsoffset must be placed before the second input (i.e. the file from which FFmpeg will take the audio ... look at the red part in the example)

src\Gpac\gpac.exe -i pipe://video:ext=hevc:audelim=true -o stdout:ext=ts:pes_pack=none | src\FFmpeg\ffmpeg_win_x64.exe -hide_banner -y -i - -itsoffset 170ms -i \path\to\your\original\file.m2ts -map 0:0 -map 1:2 -c copy -bsf:v hevc_metadata=aud=insert -metadata title="Movie Title_________________________________________________________________________" \path\to\your\output\file.mkv

Use a positive value (in this specific case, 170ms) if the audio starts before the video (aka “you have to slow down the audio”).
Use a negative value (in this specific case, -170ms) if the video starts before the audio (aka “you have to slow down the video”).

Faced the same issue with 2 another movies: 13 Hours (this movie is divided into 3 m2ts files so had to use new GAMMA build with -bluray command support) and Angel Has Fallen (single m2ts file)

The audio delay issue happened here also and it is exactly the same it was with First Man. The video is delayed by 167ms (exact same value as before which equals to 7 video frames for 23.976fps video) which leads to the audio being in front of the video and setting manual delay using ffmpeg/mkvtoolnix adds an extra step.

The fact that the exact same issue has happened with 3 different blurays I feel it could possibly be a bug and not just something due to ffmpeg?

One thing to note is that all 3 blurays have truehd audio tracks (these are the only 3 with truehd audio that I have tried yet and all of them have given the same problem) as primary and I used fel to mel switch everytime . These are the only common denominators I can see.

Hello all,

Sorry its alot to read... i hope its ok if i ask:

- Ripping with makemkv 1.15.3 rips both MEL and FEL, depending on what the disc is ofcourse?
- What is the updated way to create mkv files in the "same" way as makemkv but with yusesope tool

[Malkana]

So what process do we need to use to playback Dolby Vision correctly from the new IPhone 12 (which uses profile 8.x) via either Infuse or the internal players on the LG CX or Panasonic z1000?

hey guys, with the recent plex update it stopped triggering dolby vision on profiles 6. Now it's only working with profiles 8 and 7.
However, some of my the files I have in profile 6. Is there any faster way to change the profiles, rather than demux single layer hevc, demux with yusescope tools into bl+el, then use gamma tool to mux into profile 8 and then mux back into ts container?

Okay this is what I did for my Profile 6 TS files.

1. Use the old TSMuxer (Profile 4.06 fix) to create a Bluray folder from the TS file.

2. Create an MKV using latest MakeMKV from this Bluray folder. For some reason the output is detected as DV 7.00 (BL+RPU) by mediainfo.

3. Run the MKV through MakeMKV one more time and the output will be a DV 7.06 (BL+EL+RPU) mkv.

Does anyone know if the Bluray Player App on the Xbox Series X can run these Dolby Vision remux?

No DV support for UHD Bluray on the Xbox Series X, DV is only available through streaming apps.

Yeah but it'll be interesting to know if it too can play DV MEL (or FEL converted to MEL) titles like the Firestick 4k. Through the modified exoplayer of course, or Plex.
