Dolby Vision now possible through MP4 Mux.

[daddy]

I already checked the empty space on the drive.

DV.mp4 is 70 Go
lpcm.mov is 10 Go

This should produce a file of 80 Go and i have 160 Go free on the SSD drive.

[daddy]

Ok
I found the culprit
It s my temporary file drive that is too small

from: https://gpac.wp.imt.fr/mp4box/mp4box-documentation/

MP4Box usually generates a temporary file when creating a new IsoMedia file. The location of this temporary file is OS-dependent, and it may happen that the drive/partition the temporary file is created on has not enough space or no write access. In such a case, you can specify a temporary file location with the -tmp path_to_dir option.

I resolved the problem by moving the temporary files to the same folder i use to make the DV movies.

I made 2 "dual layer + trueHD pcm" movies (Ready Player One and Fantastic beast 2) and the method works perfectly.

There is still a problem.
The audio level is very very low when you play the movie on the tv.

if you look at the iso tracks with BDinfo, you see that there is a DN -27 dB info on the Dolby atmos tracks


I think we lose the dialogue normalisation info in the trueHD --> pcm transformation.

I think we lose the dialogue normalisation info in the trueHD --> pcm transformation.

Correct but I don't think it has much to do with your problem:
DN acts like an automatic volume control but only through attenuation (lowering)

A -27db value is telling the decoder that the average dialog is 4db higher than the -31db reference value (the reference level at which no volume adjustment is applied by the decoder) and as a result the dialnorm will reduce the levels across the board by 4 db.

As example, DTS does not use dialnorm at all.
Most Dolby tracks use a dialnorm value of -27db, so DTS tracks will usually be 4db louder.

Give us more information about your setup (Tv model, player model, pre-amp, amp, avr...)

My setup for DV:
screen: LG 55C7
player: internal, reading files from a DS416 nas by upnp
amp: Yamaha Rx-V681
speakers: 5.1 Focal Dome Flax

The "problem" is your TV: it is a device equipped with HDMI-ARC and for this reason it can only generate a compressed 5.1-channel stream with a bitrate of 1Mbps.

The input track is noticeably different: 7.1-channel uncompressed flow with a wider biterate even up to 10 times compared to that generated by your television.


How many active channels are shown on the display of your Yamaha?


According to the instruction manual, you should also be able to view the bitrate of the audio track.

ok, i understood
ARC is limiting me to only non HD sounds
i will focus only to make DV with dts-hd (dts core in my case) or e-ac3/ac3 audio.

Your method works very well.
i already remade 2 dts-hd movies in 3 hours.

I did try but it is too far complicated fo me. Hope someone will do a program for it.
Anyway congrats to you and to the author @yusesope

if you get yourself an apple tv 4k running the latest mrmc beta, it will play those 2 movies in DV with full 7.1 lossless audio. still need to test Amazon's fire tv stick 4k (much cheaper) as the emby beta app supposedly does the same thing. I'm just swapping TV's right now as I purchased a 75" Vizio Quantum X yesterday, so I'll test soon. if anyone owns that stick though here's a link to the emby beta: https://emby.media/community/index.php? ... a-testing/

I'm still working on a one-step program but I have little to no time right now

apple tv 4k can read dvhe.07 ?

oh no, I thought you were making single layer mp4s, my bad..

Hey guys,
I found an interesting paper on including TrueHD (MLP) bitstreams into ISO base media file format(mp4) - https://developer.dolby.com/globalasset ... format.pdf - I already contacted Dolby regarding a sample implementation

[RESET_9999]

Hi, Thank you for the new method to add lossless audio.

I'm using a Sony x700 with an OLED TV and so far, only the file with 7.1 lpcm works. When I make a DV mp4 with DTS-X, DTS-HD or even DTS, it plays in DV without sound. It doesn't even say '' audio not supported'', just like there isn't any audio in the file.

btw, I watched two complete movies in Dual layer with lossless 7.1 lpcm without any issue. this is really awesome.

Interesting. I had already tried it but I can't find a valid Meridian audio encoder.

You're welcome.

According to the instructions in the manual, it should not even recognize an mp4 with LPCM audio.

Hi guys
Here's an example of how to remux a dv movie composed with multiple m2ts file with the yusesope method.
Usefull programs to install in windows:
- BDInfo => https://www.videohelp.com/software/BDInfo
- MPCBE => https://www.videohelp.com/software/MPC-BE

The programs you need to make mp4 DV:
- ffmpeg => https://ffmpeg.zeranoe.com/builds/
- mp4muxer => (use the first version) https://mega.nz/file/Jawn3ADa#vN1ai3llv ... ktTQ4uFYkk
- mp4box => https://gpac.wp.imt.fr/downloads/gpac-nightly-builds/

The make those CLI tools easy to use, it s better to install ffmpeg, mp4muxer and mp4box in the same folder.


exemple: How to create the DV mp4 file with audio in French for Alita Battle Angel.
1/ launch BDinfo to see what files compose the movie


2/ with MPCBE watch the differents M2TS of the differents playlist (800,801,802,803)
If you look 800,801,802,803.MPLS ... you can see that the playlist is composed of 4 files, with differents first file and last file.
On 803.mpls, the first 00006.M2TS have the introducing text in french. So, 803.MPLS is the playlist for the movie in french.
Now if you look at the "AUDio" list, you can note that the french DTS track is numbered 1104.



3/ now we need to find the corresponding "map" number for the audio track we want to demux

Code: Select all

ffprobe -i F:\BDMV\STREAM\00006.m2ts

French = 1104 => in ffprobe this give a map number 0:7

4/ To assemble the full movie we need to create a "m2ts_list.txt" file, and list inside the differents .m2ts files

Code: Select all

file 'F:\BDMV\STREAM\00006.m2ts'
file 'F:\BDMV\STREAM\00688.m2ts'
file 'F:\BDMV\STREAM\00021.m2ts'
file 'F:\BDMV\STREAM\00689.m2ts'

5/ now here's the magical command to demux the list of the m2ts as BL and EL hevc files and audio.mp4 (containing the french dts track)

Code: Select all

ffmpeg -f concat -safe 0 -i m2ts_list.txt -map 0:0 -c copy BL.hevc -map 0:1 -c copy EL.hevc -map 0:7 -c copy audio.mp4

6/ assemble the DV .mp4 file

Code: Select all

mp4muxer_64bits.exe --dv-profile 7 --input-file BL.hevc --input-file EL.hevc --output-file mp4_dv.mp4

7/ add the audio to the DV .mp4 file

Code: Select all

mp4box.exe -add mp4_dv.mp4:rate=0 -add audio.mp4#audio:lang=fr-FR -no-iod mp4_dv_movie.mp4

8/ Et voila !

Code: Select all
