Dolby Vision now possible through MP4 Mux.

[Grencola]

- using TSmuxer to demux that .eac3 file results in a .ac3 file which CAN be used by mp4 muxer, but results in no audio during playback

This is my final step as audio works for me, both from tv speakers via usb and with my AVR. I never had to mess around any further so I apologize in not realizing renaming would be your fix.
If you open Xmedia Recode\Format\eac3.ini you'll see:

Code: Select all

[Main]
Name=E-AC-3
Format=eac3
ExtName=eac3

A1Codec=eac3
A1SampleRateDefault=48000
A1BitrateDefault=192000

AChannelDefault=stereo

You should try changing the ExtName=eac3 to ec3 then launch it and see if the pull down has changed. or you could probably add your own preset by pasting this into an ec3.ini file you create and change all eac3 instances to ec3 and up the A1BitrateDefault to 1536000 and stereo to surround etc

How can I demux mp4? I have DV mp4 in which somebody put only audio for visually impaired instead encoding proper audio from TrueHD to AC3. I want demux HEVC+DV and remux with proper audio but looks like all tools here (dv-mp4-maker, tsMuxer, aeac3to) can work only with TS or MKV. I tried convert mp4 to mkv with mkvtoolnix (DV track is wrongly remuxed), MediaCoder (only premium version is working with UHD), Total Video Converter 6, Avidemux (both don't sees DV track). Maybe is possible to add support for mp4 input into dv-mp4-maker? Or maybe there is a tool which can just add another audio to mp4 without messing with rest tracks?

if not, then this will:

Great! Thank you! mp4muxer just added second audio at the end of 50gb file, so no 50gb copying. After this file is crashing my MPC-BE but MPC-HC is working and most important file is working on LG and new track is in sync

Hi to all,

I got a few mkv remux with the second DV layer enhancement. Then i remuxed with only the ITA track and in some case separate .srt file (or embedded). Should i able to use your program for convert the file in mp4 and eventually convert the audio format (if not AC3) ? And for the subs the other app will work too ? Thanks.

not exactly sure I understand your question, but I think my tools will work for you..

I’m having an issue with Dolby Vision movies on the c7. Black bars are perfect black, but the picture which is supposed to be perfect black is only dark grey. If I look closely, there are some kinda lines running diagonally. Not sure if the remuxing process causes this. The movie I’m testing is Rampage (2018). At the beginning of the movie where there are some white texts against a supposedly black background, the background is grey instead of black. This does not happen with the hdr10 version which is perfect black.

I watched carefully the start of the movie and i saw no problem at all with Rampage on my C7.
Black are perfectly black under the introduction text.
here's my mediainfo if you want to compare.

note: No problem also for Justice League. Wonderfull picture like Aquaman and Bumblebee.
I almost done the DV versions for 30+ files, but i did it mostly from m2ts (i think 90%).
The only problem is that sometime tsmuxergui (2.6.12) is unable to extract 2hevc+1audio tracks at the same time.
The solution for this is to extract one by one all the tracks you want to use.

So I finished remuxing the dolby vision mp4 of the movie Rampage using m2ts file and the result is the same. Still raised black. If I increase brightness from the default 50 to 60 you can see the picture part gets brighter than the black bars, indicating raised black level: https://i.imgur.com/Dgs4gRZ.jpg. I do the same thing for the dolby vision of Robin Hood and the brightness of both picture and black bars increase at the same rate: https://i.imgur.com/e6XwEey.jpg, so no raised black there. So I believe it’s because of the movie itself. I’m surprised you don’t see raised black in Rampage. Did you watch it in a completely dark room (because it is unnoticeable with any sort of ambient light)?

How can I demux mp4? I have DV mp4 in which somebody put only audio for visually impaired instead encoding proper audio from TrueHD to AC3. I want demux HEVC+DV and remux with proper audio but looks like all tools here (dv-mp4-maker, tsMuxer, aeac3to) can work only with TS or MKV. I tried convert mp4 to mkv with mkvtoolnix (DV track is wrongly remuxed), MediaCoder (only premium version is working with UHD), Total Video Converter 6, Avidemux (both don't sees DV track). Maybe is possible to add support for mp4 input into dv-mp4-maker? Or maybe there is a tool which can just add another audio to mp4 without messing with rest tracks?

This should work: https://www.videohelp.com/download/mp4muxer-0.9.3.zip
if not, then this will:
http://ffmpeg.org/download.html

To demux there is the mp4demux program from DolbyLaboratories too : https://github.com/DolbyLaboratories/dlb_mp4demux

yea this too could work, just wasn't sure if the visually impaired audio track was ac3 or something unsupported, so figured he'd be better off with the others.

I did two remux with the mp4demux and it works really good.
step1 : put a dv.mp4 file in the working directory
step2 : demux the mp4 file => mp4demuxer_64bits.exe --input-file dv.mp4

At the end of the process you have 3 files:
- out_1.h265 : the hdr10 track (bl.hevc)
- dv_el_out_2.h265 : the dv track (el.hevc)
- out_3.dat : the audio track

I made a zip file with the mux and demux tools : https://uptobox.com/3hfxq39xllsm

cool man, good to know. maybe I'll add the mp4demux files to my tool for when it detects an mp4 file it demuxes it, and still muxes if it sees mkv or m2ts.. or maybe not not sure how many people would need to demux their mp4s

So after lots of testing, it seems that this process of demuxing and remuxing into mp4 does sth weird to the file. I’m watching the movies on my oled c7, and every single dolby vision movie created using this method has some kind of noise (diagonal lines running continuously). Now you may not notice this if you don’t watch movies in a completely dark room, so one way to see this issue is to turn up the brightness from the default 50 to around 55-60, put your eyes near the screen and you will see the lines. Yesterday I downloaded several dolby vision demos online which were not created using this method and they do not have this kind of picture noise. Can anyone confirm?

Great! Thank you! mp4muxer just added second audio at the end of 50gb file, so no 50gb copying. After this file is crashing my MPC-BE but MPC-HC is working and most important file is working on LG and new track is in sync

Hi. When I add a second audio with mp4muxer, my LG C7 shows both tracks, but only plays the first audio (even when I select the second track in the LG internal player). Have you done any aditional task to play both tracks in the LG TV?

Thanks

Hi to all guys,

so demux the audio track in DD+ (E-AC3) format with tsmuxer result in playable audio with LG TV C8 ? Im still dont get this point. Thx to all.

I have LG C8, too. If you demux the TrueHD track you usually get a 640kbs. If you have a native DD+ track at 1.5Mbit then use that. What I have been doing is demuxing the 1.5Mbit DTS track, then converting it to DD+. Both my LG C8 and my Sony X700 see it properly with the bitrate.

instead of just extracting the 640kbps ac3 core from a thd track, you can also demux the whole lossless thd track and convert that to 1.5mbit dd+ using Xmedia Recode, as per page 5 of this thread
