I have tried MBOX demo video files on my iPad Pro, it seems that P5 can be identified as DoVi by infuse 6, but P8.1 can not.
Result:P5 play as DoVi, P8.1 play as HDR, I have uploaded these screenshots.

I forgot to mention one very important info: Apple require the video track fourcc ID to be “dvh1” for Dolby Vision. So you need to change it manually using a Hex editor. (More info: the sample I recommended to you is “dvhe”, which cannot be played by QuickTime/Apple TV app)

Furthermore, Infuse only supports profile 5. If you want to test profile 8.x, you need to copy the the m4v file to the “Files” app, and preview with it. (And you must use iPadOS 14.1 or 14.2 beta 4, or later versions, in order to support profile 8.x)

The first command line is fine, in the second there are two invisible mistakes!
You entered two "newline" characters (sei andato a capo due volte): one immediately after title= and the other after the underscores and the quotation mark (before the address of the output file).
Look HERE.

The command line is a single long line and the only spacing character allowed is the space.
You can help yourself with THIS online tool for removing line breaks.

the second command line should be (look at the parts in red):

No space between title= and the next quotation mark.
A simple space between the last quotation mark and the address of the output file.

However, sample made by yusesope's "-mode 2" triggers crash on macOS Big Sur, while encoding sample from MBox does not. So there are still room for improvements.
The mysterybox sample (the one with profile 8.1) is FHD (1920 × 1080): did we download the same file?
Mine are UHD (3840 x 2160): it would be an unequal comparison :mrgreen: !

Would you tell me exactly which sample produced by my tool you tried? It is important to know because "-mode 2" has undergone some changes over time!
I leave you a SAMPLE (video only - profile 8.1 derived from a FEL) obtained with the latest version of my tool and adapted to meet what I believe are the needs of macOS Big Sur. I don't know if it will be played but it doesn't hurt to try!

The correct codec ID (for profile 8.1) should be "hvc1" in place of "hev1". But be careful, these boxes are not random: they indicate to the decoder how the information for the initialization of the latter is stored within the file. Changing the header with a hex editor isn't always enough!

Thanks for the reply.
I checked the versions
Plex Player is latest version : 8.7.2.20952
Plex server is also latest version : 1.20.3.3437
After re-anilysing the file it showed the DoVi data. But playing the file was still in HDR :(
You need the latest 8.8 version of plex. If you weren’t on the beta, i think the public releases just came out today.
Thanks....gonna download that one tonight and see if it works.

EDIT: Update Plex app to 8.8 and worked indeed. Thanks!!
Hello, I downloaded the version PLEX 8.8.0.21167, but when I release mkv, it doesn't start in Dolby Vision, but in HDR. Can you advise what it could be?

Tried your new sample, but it does not trigger DoVi on macOS Big Sur.
It plays in HDR10 mode, and works fine. Good job. Guess Apple does not support profile 8.1 after all (but still don't know why QuickTime can play the incorrect profile 8.1 files).

Another interesting phenomenon is that your Terminator sample can be edited with Apple's Photos app, as well as latest version of iMovie on iOS. So I tried to re-encode the video with iMovie, and I got THIS file (DoVi profile 8.4 compatible with HLG, 30FPS, 1080p).

This proves that the latest version of your tool works perfectly with Apple devices! The RPU data is 100% compatible with Apple's Dolby certificated encoder!!!
Please share a Mac version of your tool, or just the source code, so I can test it on my machine!

Thanks for your reminding! You are right. I also double checked the iPhone 12 Pro sample, can confirm that profile 8 does not use "dv**" FourCC.

I also tried to change "dvh1" to "hvc1" of the MBox profile 8.1 sample. The resulting file can be played in QuickTime (contrast still wrong), but cannot be played on my iPad. This is what I could't understand. It should be at least backward compatible with HDR10, like your Terminator sample.

However, change FourCC in profile 5 file ("dvhe" -> "dvh1") works (for both HD and UHD samples)!

Thanks Yusesope again. Followed your advices and made an entire movie in prof 8.1 which plays DV in Firestick.
My remaining problem is how to choose the italian audio track from the m2ts. I know for you would be easy but for me is impossible to do.
Anyway you are simply an extraordinary man.

EDIT:
After many trials and hours I am capable to make the mkv with audio and subs chosen by me.
From scratch to the final mkv it takes less than 1 hour. Excellent, Master Yusesope, your Gamma version of the Tool works very well.

Doing the first post, will that be enough to have the best version? Or was there some advance in the entire discussion. I already tried with matrix and transformers, and everything ok with the tv

Some people have said you need to force a re-scan of your metadata for all Dolby Files, as Plex has already stored them as HDR10 playback.

I tried it in the evening and some movies play Dolby Vision and some only play HDR. What can it be?

After Plex version 8.8.0.20999 most DV profile 6 movies play as HDR, but some still do play Dolby Vision. Apparently something changed. Re-scans etc dont help. If i go beyond this version it happens en when I go back DV activates normally again for all movies. So for now I stop updating the app. Using the latest server gives nog problems relating above isues.

Bravo!
I knew you could do it!
Come on, honestly, it's not that complicated.

I am happy to know that the GAMMA version is working properly. In the future I will try to make everything automated.

An hour seems too much! When you run the second command, FFmpeg should show you the speed with which it processes the data I send to it: I oscillate between 6x (mechanical HDD) and 15x (NVMe). It means that a 2hr movie is processed in 20min (120/6) or 8min (120/15). My current CPU is an i5-7500.

I'm sorry but not having a Mac I can't continue to support this platform.
You have several options though. The easiest and fastest (15 minutes and everything is ready) is to use VirtualBox (free) or Parallels (trial) with the image of a virtual machine (ready to be started) with Windows or Linux OS.

Keep in mind that my BETA version returns a raw HEVC file while the GAMMA a full MKV file.
The MP4 I posted to you was obtained by modifying the source code of Dolby's mp4muxer (and using a raw HEVC stream obtained with BETA)).

This file is important for anyone who wants to encode (x265) their files with DoVi.
This is a correct encoding: not only the Base Layer has been changed but all the RPUs have been recalibrated.
The encoding was done through a certified encoder!
It is wrong to encode the Base Layer and "re-paste" the original RPUs through my tool!

I also took a closer look at your video (recorded with iPhone 12) and the file obtained with iMovie.
The coding scheme is virtually identical.
I then extracted all the RPUs present in your video, in my sample (Terminator) and those in the Terminator encoded with iMovie (zip HERE).
Open the CHECKSUM.md5 file (found in each folder) with a text editor. Inside are the md5 hashes of each individual RPU.
In files produced with iOS, there are many identical MD5s and therefore many identical RPUs.
The strength of Dolby Vision should be precisely that of dynamically varying the characteristics of the image (but I don't think it can happen if there are many identical RPUs).
Then I looked at some (not all) RPUs (the ones with different md5) and the only parameters that vary are max_PQ* and avg_PQ*.
The variations are also minimal.
It seems to me a fairly minimal implementation of Dolby Vision technology.
The UHD-BD RPUs are all different from each other and the parameters that change are multiple, frame after frame (see the CHECKSUM of my sample)

I also tried to change "dvh1" to "hvc1" of the MBox profile 8.1 sample. The resulting file can be played in QuickTime (contrast still wrong), but cannot be played on my iPad. This is what I could't understand. It should be at least backward compatible with HDR10, like your Terminator sample.
As I said, very often it is not enough to change the header of a box for the file to be played. QuickTime is perhaps smarter and can retrieve the information needed to initialize the decoder. The iPad player may not be capable of it!

I am still refining the whole process, You are right, it takes less time. On my pc between 20 and 30 minutes, depends also if the original movie has got HDR10+ and I want to remove it for compatibility problem with Firestick. In that case the process takes a little more time.
My processor is an I3 6100.
