Have a little update. I created an MP4 example with chapters for the Plex team.

4K Single Layer Dolby Vision (with EAC3 Stereo) and six “synthetic” Chapters

https://drive.google.com/open?id=13swFiP...0w_5jxk4UB

It is the LG Test Video "LG Earth Dolby Vision UHD 4K demo.ts" + Chapters as described in my method

### TrueHD (Atmos) Commad ### #EXPERIMENTAL# - You get a soundtrack in the format: mlpaffmpeg.exe -i bluray:\path\to\bluray -map 0:AUDIO_STREAM_ID -c:a copy -strict -2 %userprofile%\Desktop\atmos.mp4
 

I cant get this working:



[mp4 @ 00000161893400c0] Tag AC-3 incompatible with output codec id '86060' ([0][0][0][0])
Could not write header for output file #0 (incorrect codec parameters ?): Invalid data found when processing input

Any idea? im new to this

So I'll turn me on here. I have a new Shield 2019 Pro and I'm also a Plex Pass (Beta) Member. I'm a big fan of Kodi since XBMC times. Unfortunately, I'm currently very dissatisfied with the Plex Android TV app, as many soundtracks are not working properly or incorrectly via HDMI passthrough. Kodi with the Plex addon is currently the best solution for me, because everything works wonderfully. Now only the Dolby Vision Support is missing  As already mentioned, an MP4 in single layer format is needed.

First, here's a very important link on Dolby Vision Rips:
https://forum.mrmc.tv/viewtopic.php?f=15...&start=310

What you need and how to create a perfect DV single layer rip with and without HD sound:
- DVDFab (current)
- FFmpeg (current)
- mp4box (from GPAC SDK - gpac-0.9.0-DEV-latest-filters-x64.exe)
- MediaInfo (for control)

The simple variant:
You can create a single layer rip with DVDFab. Attention you have to set this first, because the standard dvdfab profile creates a dual layer MP4! Disables Web optimization. At the soundtrack you can click on "copy". In that case, you will receive an AC3 from a TrueHD and a DTS from a DTS-HD soundtrack (I'll be right on the subject of hd sound). The subtitles are extracted and saved separately. Here you choose SRT subtitles! This is the easy way that is currently possible. However, without HD sound and without chapters. This does not make DVD Fab currently. I hope it will follow.

The ultimate variant:Step 1 - Extracts the HD sound from the ISO or from the disk with FFmpeg.
### How to find the correct stream id ###
ffprobe -i bluray:\path\to\bluray
Now find the right track and notice the AUDIO_STREAM_ID like 0:2

### DTS HD Commad ###
ffmpeg.exe -i bluray:\path\to\bluray -map 0:AUDIO_STREAM_ID -c copy %userprofile%\Desktop\dtshd.mp4

### TrueHD (Atmos) Commad ### #EXPERIMENTAL# - You get a soundtrack in the format: mlpaffmpeg.exe -i bluray:\path\to\bluray -map 0:AUDIO_STREAM_ID -c:a copy -strict -2 %userprofile%\Desktop\atmos.mp4

Now you have your HD soundtrack in a MP4: atmos.mp4 or dtshd.mp4

Step 2 - Creates a chapter TXT file and call it "chapters.txt"
I always find the times of the chapters with MediaInfo. If you have the times and if necessary the names of the chapters, write the following points in the TXT:
Example:
CHAPTER01=00:00:00.000
CHAPTER01NAME=Chapter1
CHAPTER02=00:10:15.698
CHAPTER02NAME=Chapter2
CHAPTER03=00:22:39.399
CHAPTER03NAME=Chapter3
CHAPTER04=00:35:53.276
CHAPTER04NAME=Chapter4
CHAPTER05=00:43:55.007
CHAPTER05NAME=Chapter5
CHAPTER06=00:55:19.357
CHAPTER06NAME=Chapter6
CHAPTER07=01:03:10.161
CHAPTER07NAME=Chapter7
CHAPTER08=01:14:12.364
CHAPTER08NAME=Chapter8
CHAPTER09=01:26:01.698
CHAPTER09NAME=Chapter9
CHAPTER10=01:37:16.080
CHAPTER10NAME=Chapter10
CHAPTER11=01:48:24.456
CHAPTER11NAME=Chapter11

Now you have a chapter file

Step 3 - Created with DVDFab a single layer rip (including external subtitles) as already described in the simple variant. For example, call it "dvdfab_out.mp4".

Step 4 - Now create the ultimate Dolby Vision Rip for the Shield 2019 with the mp4box:

mp4box.exe -add %userprofile%\Desktop\dvdfab_out.mp4 -add %userprofile%\Desktop\atmos.mp4:lang=eng -add %userprofile%\Desktop\chapters.txt:chap -brand mp42isom -ab dby1 %userprofile%\Desktop\mp4box_out.mp4(Varying commands depending on the language = atmos.mp4:lang=Language_Code like eng or ger)

Now you have a 4K single layer Dolby Vision MP4 with AC3 and TrueHD (mlpa) including chapters and external subtitles.

If you want, you can also muxe the subtitles. But for me that has no added value compared to external subtitles. Name the subtitles exactly like your video (and if necessary additions) so they will be recognized.

Example in my case:
Hellboy 2019.mp4
Hellboy 2019 .ger.srt
Hellboy 2019 .ger.forced.srt

I hope I did not forget anything - if questions are just ask....

When doing the "DTS" version the files wont play with MX Player on 2019 Shield (TrueHD i have a problem extracting, see post above this), i get a black screen with sound, how are you playing these?

@box4m 

I play every DV content with plex.

Check your commands again. Here two examples:

To find the ID

Code:

ffprobe -i bluray:W:\

DTS-HD:

Code:

ffmpeg.exe -i bluray:W:\ -map 0:2 -c copy %userprofile%\Desktop\dtshd.mp4

MLPS (True HD)

Code:

ffmpeg.exe -i bluray:W:\ -map 0:2 -c:a copy -strict -2 %userprofile%\Desktop\atmos.mp4

"ffmpeg.exe -i bluray:W:\" - what do i typ in "bluray:W:\" - i do X:\FOLDER\BDMW\STREAM\something.m2ts

[KingCarstonoX]

"ffmpeg.exe -i bluray:W:\" - what do i typ in "bluray:W:\" - i do X:\FOLDER\BDMW\STREAM\something.m2ts 

"ffmpeg.exe -i bluray:W:\" is exactly what I enter if there is a disc in the drive or an iso

Accessing the file directly works without problems for me:
"ffmpeg.exe -i W:\BDMV\STREAM\00xxx.m2ts ..."

check if you have the latest version of ffmpeg and start the console as admin.

Plex on my 2017 Shield also plays back single layer DV files as HDR10. I wonder if its doing the dynamic tonemapping internally and outputting it in an HDR10 container?

DV is backwards compatible as HDR. Its nothing special about the shield or kodi.

I didn’t think single layer DV was which is why discs have dual layer DV.

I'm also surprised. Singel Layer DV is not backwards compatible. Which player are you playing the video with? Are you sure it's a single layer?

[KingCarstonoX]

Oh something else, not so nice news... DVDFab single layer rips are a fake

Dolby has no intention of subsequently creating a single layer from dual layers. The color space is wrong and the metadata is said to be static.

https://forum.mrmc.tv/viewtopic.php?p=27097#p27097

If you look at the Dolby documentation, you realize that he must be right.
https://www.dolby.com/us/en/technologies...-paper.pdf
https://www.dolby.com/us/en/technologies...levels.pdf

There are now three options that are not yet 100% clear.
1. Is it just a fake what is an HDR10 but does Dolby Vision trigger on TV?
2. It is a better HDR10 with some vision metadata ?
3. DVDFab has really found a way to integrate it ?

Obviously, this can only be found out with professional software that is not available in this way.

So now also the request whether the Shield 2019 makes dual layer with profile 7 possible..!?

Maybe I am just misisng the annoucement and even not finding a feature request thread. But it seems not on the list so far. But it would be really great if we can have Dolby Vision Supported in next (major) release

Don't punish me if I missed sth

I also wold like native HDR in Kodi... out of the box!
