Dolby Vision now possible through MP4 Mux.

In profile 5 (single layer) there is no enhancement layer.
In profile 7 (dual layer) there is an enhancement layer that is 1/4 the size of the main UHD layer.



So, a profile 5 DV file have the DV already applied to the video. This mean that if you read this video on a hdr10 system, the color are false.
In profile 5 you lost the hdr10 compatibility.

One requires hardware (double layer) one can be done in pure processing power(single layer)

This is false. Do you need a specific hardware for decoding dts-hd or truehd ?? no, this can be done in software.
For dual layer DV we just need a video player capable of reading 2 hevc streams at the same time.

There is already a project of plugin started by dolbylaboratories : https://github.com/DolbyLaboratories/do ... der_plugin

Dual layer stream support is not implemented. This example may be a good base for adding this feature, however.

For dual layer DV we just need a video player capable of reading 2 hevc streams at the same time.

And that is the bit that needs the hardware in the player to support it, Nvidia Shield for instance doesn’t have hardware that can play 2 streams at once so it can only play single layer....

is there a difference between DV-mp4 and original DV with the eye? has anyone tested yet?

I actually just found a "blemish" in my Hannibal mp4, in 2 scenes I've noticed blow out highlights: extremely artificial-looking blocks of pixels, and all on light reflection off of character faces in interior scenes, not talking about sci-fi high intensity laser blasts...

I only "noticed" them because they jumped out at me, didn't "notice" them playing the disc (fairly certain they weren't there). it's gonna be quite a work out if I were to try to hunt these specific scenes down to capture on camera for demo.

but does it mean anything? IDK. of all the components in the entire ecosystem of ripping/converting/playing/displaying the file, somewhere a "glitch" happened? can't say, or this is just a one-off event? IDK.

Could just be your playback device, is the disk player and MP4 player the same device?

So i just wanted to do quick write-up about an issue I was having over the past couple of days trying to get Alita: Battle Angel setup and working with yusesope's player.
I was having an issue with mp4box throwing "incomplete box" errors and not playing in yusesope's player(playback failed, error), as if the file was incomplete or corrupted.
come to find out dvdfab had somehow messed up the output. this was discovered by using Mediainfo on the dvdfab output, which showed me "istruncated: yes"
did some more testing with ripping the disc multiple times, in multiple ways, with the same results.
then i noticed the "choose other titles" option in dvdfab. and low and behold there was a whole lot of other streams, several of which where smaller than the full thing.
Went through previewing the titles and they were all(aside from the big main title) parts of the whole.
so as an experiment, I found all the parts to make the whole. and once outputted none were truncated (good sign).
individually tested each file to make sure they worked with yusesope's player, and they did.
then with a little research on mp4box and found the it can actually combine (referred to as concatenates) multiple videos
so with this command and i was able to get the file up and functioning

mp4box -add video1.mp4 -cat video2.mp4 -cat video3.mp4 -cat video4.mp4 output.mp4

Now if you do need to use this make sure you input the files in the correct order.

and so far this has seemed to work just fine.

It's been a while since I was on this thread. Any update to the method or Grencola's tool (mine is v2.0) is still the best here? Anyone got the c9 oled and can confirm the DV files are still working on that tv?

I could kiss you!
I just tried this and worked perfectly, I didn't watch the entire movie but everything is in sync, I even made a DTS-HD MA 7.1 audio from the Atmos and that sync'd up just fine.

glad to hear that it was helpful.

Anyone could explain, or point to a post where i can read about how to play/install yusesoplayer on 2019shield?

Thank you

yet play in dolby vision with the basic sideloaded mx player.

Is MX Player capable of managing Dolby Vision streams?

Yes it is, to my surprise. It doesn't support frame-switching though, which is a deal breaker for me since I don't want to watch my 24fps movies in 60fps. hoping your player will do this?

Does MXPlayer play DV mp4 single layer that are made with dvdfab+ffmpeg+mp4box ?
I only get picture+audio with files that are 100% made from dvdfab, dvdfab+ffmpeg+mp4box i only get sound and a black picture, and i dont know how to check if its playing DTS in mxplayer?

If it works for you, what method are you using to get single layer mp4 DV with DTS?

All above is with 2019shield

[DaMacFunkin]

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

I used the fire tv stick 4k since I don't have a shield yet. it only worked with one title and not great, but all the LG DV demos work just fine.

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.

[Dolbyvisonchaser]

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..
