Behemoth thanks to yusesope and Grencola, you guys are doing fantastic work for our dream of DV.mp4.atmos. I've also voted on the plex forum.

What happens is explained HERE (starting from line 650).
Translated into human language:
if the difference between the expected playback time and the playback time obtained from the audio analysis is greater than 200000 (microseconds) then calculate the "adjustmentUs" value (line 659) and add it to startMediaTimeUs (line 660).

This operation is repeated for hundreds of times.
I noticed that the difference between the expected value and the one obtained is always 212500 μs (slightly higher than the value in the code).
If you do the maths, the value of adjustmentUs will always be equal to -212500 μs and consequently the value of startMediaTimeUs will be constantly decreased.

What does this mean?

the second value (the meaning of the others can be found HERE) indicates the current playback time and is negative.
Instead, it should be positive and it should increase over time (as it happens in all media players).

Here's what happens, the audio is played but the video track is not because it is constantly delayed (it practically never starts).

How do I try to solve the problem?
Increasing the value present in the code (from 200000 μs to 400000 μs).

I don't know why 200000 was chosen (maybe someone can explain it to me).
It seems to me an arbitrary value useful to keep the audio in sync: what could go wrong if I change it slightly? :mrgreen: :mrgreen: :mrgreen: :mrgreen: :mrgreen:
I don't know if this will solve the problem but there is no harm in trying! :D

unfortunately I get the same result as before, negative time is shown on the navigation bar. Sooo close, keep up the great work, sorry I don't have a debug file, need to set that up but too late tonight.

yusesope, I've tried a few of your test files using YusesoPlayer on the Amazon Fire TV Stick 4k and I get the same result: working hd-audio and dolby vision flag on the tv but just black video. However the single layer dvhe 5.06 mp4 sample files from LG play perfectly in dolby vision, both with your player and in mx player. getting close :)

Following the single layer DV guide with DTS audio is working great but the file sizes seem a lot smaller than the original m2ts files, is some compression going on or is it just due to less streams being in the output? Wondering if I have something set wrong in DVDFab, although it does say it's just copying.

Hello peepz! Need some pointers - I have a dual layer dv movie remux in mp4, would like to convert that to a single layer mp4 with DVDFab to test on the new shield TV.

Following the single layer DV guide with DTS audio is working great but the file sizes seem a lot smaller than the original m2ts files, is some compression going on or is it just due to less streams being in the output? Wondering if I have something set wrong in DVDFab, although it does say it's just copying.
the process is lossless.

I don't think you can do that. You need to rip from the ISO/folder structure.

quick question, how do you deselect audio track in DVDfab? I'm demoing the software, I found the single-layer/dual-layer options in settings, but for the life of me, I don't see any option to not select any audio stream to create just the video stream for mp4box. god I feel dumb...

you could try Dolby's mp4demuxer, and then use tsMuxer to create an m2ts file from that to feed dvdfab.

With DVDFAB, you cant. You remove the first audio when you add the lossless audio with mp4box:

Code: Select all

mp4box.exe -add X:\dvdfab-single-layer.mp4#1 -add X:\lpcm.mov#audio:lang=en-EN -tmp X:\ -brand mp42isom -ab dby1 -no-iod X:\dolbyvision-remux.mp4

Before continuing on the path taken, I would like to test a new idea.
Those interested can download the new app and the new server HERE and the new sample file HERE.
I recommend limiting yourself to the file I uploaded (it's special :D ). You will find in the archive a TrueHD/ATMOS track and a DV dvhe.05 track. Both must be loaded into the server in the usual way.
The IP address of the server remains 192.168.1.130 and to change it use the previous instructions.
If the idea proves to be successful, I will explain to you how to rework the files you own.

As always I thank you for your feedback.

It's working with Atmos and Dolby Vision, I had to select Atmos on my AV receiver though, on previous demos it automatically triggered Atmos but this may just be an issue with my setup. Using a Shield TV Pro 2019, LGC6 and Denon X2500

Can confirm this split method (sample file) does work no problem. Vizio Quantum X, Denon AVR-S750H, and shield tv pro 2019.
