Dolby Vision now possible through MP4 Mux.

[DaMacFunkin]

Plex on Shield doesn’t match frame rate for Dolby Vision either, according to devs it would have to be implemented by Nvidia.

omg seriously?! well shit. this means there is literally no media streaming device capable of playing back our UHD DV movie backups with HD-audio in 24fps The ONLY option to get it all would be to either use a UHD-BD player, a Chinese Oppo clone, or be lucky enough to own one of the VERY select few TV's that support e-arc/hdmi 2.1 where you'd play the full m2ts from either its usb player or (possibly) plex. brutal.

Just set the output of the Shield to output 4K 23.976 and HDR10 + Dolby Vision, that’s what I do, most apps such as Netflix and Plex will change back to 50hz or 60hz when required

Yea you just have to manually set it. They're talking about auto-changing and nVidia has been clear about some very big limitations around that on the new SHIELD. It will never be truly automatic according to them. I don't think the Refresh Rate app works with DV, either, although I've not tested it. (Still have to get the app set up correctly for ANY uses, actually). But set it manually before you play your content and it's fine. Not as convenient, sure, but, it'll work.

Hi guys,

Didn't know if anyone wanted me to post the python script or a detailed guide on how to do it.

What I have done after reading all the comments is added a constant beep audio file to a Dolby vision MP4.

Then from my TV headphone port I used a audio jack to my pc mic in port.

Using the lav filters guide to play the Atmos track.. basically have a script on the pc listening for the beep, as soon as you click play my script will click play on Atmos file and the audio to my eyes look in synce.

Not the quickest way, consider can get a audio jack cheap.. best way for now get true hd audio and Dolby vision

fair enough, can't force refresh rate on the ATV stick 4k but knowing the shield has a solution is a start I guess..

I wouldn't mind taking a peek at it, sounds promising..

Hi again

There are 966 posts and counting, each either building upon or modifying previous ones. Can someone PLEASE summarise what needs to be done to:
1. Encode a DV file so that it can play a DV file on the Shield 2019?
2. Play existing DoVI files on shield 2019?

Thank you.

[Dolbyvisonchaser]

Managed to finish coding this... please bare in mind this is just about stable
https://www.4shared.com/rar/ubS7CcxFiq/scratch.html

Please bare in mind steps get this sorted are pain in the rear end but will work quickly when set up

What I would recommend doing first is download a mp3 of this youtube video:
https://www.youtube.com/watch?v=z96MAvcAEFA

Then copy about 3 or 4 of them audio files into a folder, then follow this guide on how to concatenate them together:
(To make a 4 hour version)
https://trac.ffmpeg.org/wiki/Concatenate
Then get the run time of your blue ray movie
ffmpeg -i bluerayloaction -f null -
Then use this time with the below code: (Enter your times this is a example)
ffmpeg -i yourfile.mp3 -ss 00:00:00.000 -t 02:01:49.09 -c copy x2.mp3

Now after all that have a constant beep audio file same run time as your film

Then just combine it with your dolby vision mp4

ffmpeg -i F:\yourblueray.mp4 -i x2.mp3 -c copy F:\finishedfilm.mp4

Next need the atmos file so follow this:
https://forum.mrmc.tv/viewtopic.php?f=1 ... 425#p25425
Command:
-map 0:AUDIO_STREAM_ID -c copy -strict -2 \path\to\audio.mp4

Then set up mpc-be on your pc:
https://t3chguides.wordpress.com/2015/0 ... v-filters/

Please note can not have a HDMI plug in the arc port of the tv, change it if it is in that.

Plug a audio jack from your TV headphone port and select it from the audio section and then plug it in your pc mic port.
Before playing the film on tv, open my script and run scratch.exe from cmd, select your microphone port should be number one unless using a sound card.

Then open the atmos file in mpc and make sure it is on 0 and also my script will click space to play need to keep on the play can not click of it. Then just play the film on the tv and it will start playing the atmos file at the exact same time

The only way to get DV to play via Plex on the Nvidia Shield 2019 is to use DVDFab UHD Ripper which is worth it. You have to merge the two layers into a single layer which means it will only play on a DV capable display. It also plays on the TCL R617 as well which doesn't support Dual Layer Dolby Vision a Google limitation on Android based devices including the Shield.

[piidii]

make this script:
open a new text file and paste in:

ren *track1.hevc baselayer.hevc
ren *track2.hevc dvlayer.hevc
ren *.ac3 audio.ac3
mp4muxer_64bits.exe --dv-profile 7 --input-file baselayer.hevc --input-file dvlayer.hevc --input-file audio.eac3 --media-lang eng --output-file movie.mp4

save it to where you keep your mp4muxer exe, and rename it to startmux.cmd

then whenever you're done demuxing a movie and converting audio, just place a copy of mp4muxer and startmux.cmd into your chosen demux folder and double click on startmux.cmd

I've just tried that but nothing happens. It starts to write to my HDD, creates the file movie.mp4, after ~15 mins the cmd prompt closes and the output file movie.mp4 is 0 bytes in size...

oh oops, thx for pointing this out, I edited my original post. put this in startmux.cmd instead:

ren *.hevc baselayer.hevc
ren 0*.hevc dvlayer.hevc
ren *.ac3 audio.ac3
mp4muxer_64bits.exe --dv-profile 7 --input-file baselayer.hevc --input-file dvlayer.hevc --input-file audio.eac3 --media-lang eng --output-file movie.mp4

I have exactly the same problem. Still 0 kB. If i close CMD after while it will have a size 1 kB. I really dont know what im doing wrong. Can you help me please? Im trying that on Windows 10. Thank You!

Could someone take a look at this and see if there's anything that can be done:

Instead of a dedicated dolby atmos home theater system, I'm using Dolby Atmos for Headphone (DAfH), hoping that I can get that atmos experience watching ultra hd movies. The thing is: almost no media player on pc can decode dolby atmos and make it work with DAfH (all they can do is sending 7.1 data without atmos to DAfH and DAfH will upmix the signal). The only media player that can decode dolby atmos is Windows 10 Movies & TV app, but it can only decode DD+ based dolby atmos, not TrueHD 7.1 based dolby atmos, and all ultra hd movies only have TrueHD 7.1 based dolby atmos. Is there a way to convert the truehd 7.1 dolby atmos stream to e-ac3 (DD+) dolby atmos stream so I can get dolby atmos using Movies & TV app?

Some videos for reference:
-Dolby Atmos test tone: https://download.dolby.com/us/en/test-t ... _9_1_6.mp4 (this video has DD+ based dolby atmos stream, so watch this with Dolby Atmos for Headphone using Movies & TV app, you will hear that the height channel is there)
- A comparison video I made: https://youtu.be/LRTCv1WcPfI (you can hear that using dvdfab (or any other media players like vlc, mpc, powerdvd etc.), the height channel is not there, but using Movies & TV app brings back the height channel)

OK so I ripped Godzilla KOTM and it works but the audio defaults to AAC. So even though it probably won't work, I'm going to try Atmos. Interestingly it works on the default player but not on VLC, Kodi or my file manager. Later on, I'm going to try it also on my Apple 4K.

*edit
Nvidia Shield & Apple TV 4k Play the Dolby Vision rips from DVDFab. I use EAC3 which effectively gives me lossy Atmos.

On the shield, Plex & MX Player play Dolby Vision with EAC3 and DTS.
Apple TV also plays the above with MrMC.

[deadchip12]

It's possible that tvs will support both dolby vision and hdr10+ in the very near future. Is there a way to make hdr10+ work through mp4 mux like dolby vision? I checked the Alien 4k Remastered disc (an hdr10+ title) and it seems there is only 1 video stream (compared to usually 2 streams in a dolby vision disk).
