[Feature Enhancements ] Dolby Vision and Atmos support on devices like (Web, Android,Android TV,Apple TV and etc..)

[CyberPoison 32]

Hi as i can see the exoplayer is nearly to get a major update like allowing Dolby Vision from .mkv containers and looks like MKV standard it's nearly to support it and as soon the MKV get support for DV (Dolby Vision) exoplayer will be upgraded as soon.

 

Mastroka Standard

https://github.com/cellar-wg/matroska-specification/pull/390

 

ExoPlayer

https://github.com/google/ExoPlayer/issues/7267

 

BTW, as I read I found than ts(Containers) and others already support (Dolby Vision).

 

But I also would like than Emby add some transparent icon or something that display than the content is well in Dolby Vision and Atmos an Transparent icon/tag/logo for exemple at the beginning at the movie during 10 Seconds (Usually the time of the intro scene) and at the movie UI Wil be nice.

 

FYI.

MKVToolNix implement it in the next version

 

https://gitlab.com/mbunkus/mkvtoolnix/-/issues/2784#note_335568674785a60fd09cfbbf3b873780a63a1513

 

So conclusion.

 

Support Dolby Atmos + Vision with and logo/icon/tag whatever you want(I prefer a tag and a icon) on the movie, music UI to see than that movie have that support i also know than other concurrents are working on this implementation. So hope than emby is the first one.

 

Nvidia Shield already support Dolby Vision and Atmos and many tv and sound bars support Atmos unfortunately there is no info on the movie,music UI to show us properly than the movie,music have Atmos and/or have Dolby Vision.

 

And also create a filter to add this as a tag to select directly the movie have Atmos and/or Dolby or each one (Dolby Vision or Dolby Atmos)

 

 

 

Like this. VOTE UP for this enhancement

 

Kind regards

Edit:

 

I'm talking about support for this Atmos if it's already implemented

1° Dolby Digital Plus + Atmos, aka “EAC3 + Atmos” aka “Lossy Atmos” aka “Streaming Atmos.”

2°TrueHD + Atmos, aka “Lossless Atmos "

 

This feature is for every device as support it.

So as you can see on Nº3  you are not able to put Dolby Vision Single Layer on Mastroka format with my build (But some users have done it already with the codec MpegH HEVC Main10@L5.1 (dvhe.07.06 BL+EL+RPU FEL). For now, but still to be implemented on exoplayer and it will be in mkv standard nearly.

on the other hand with mp4 you are allready able to read Dolby Vision (NOTE: Looks like there are 2 Videos Ouput one 1080p and other 2160p)

Codec configuration box                  : hvcC+dvcC

So on mp4 you are allready able to see mp4 dolby vision video formats not sure than emby support it allready 

But when exoplayer get merged the MKV DV Support, don't forget to put some tags/logo on Movie UI and add the Media Info like i describe bellow  on Movies Info,Filters.There are tag missing in filters such as HDR,HDR10,HDR10+,Dolby Vision,Dolby Atmos and just to remember if you can (But i thought you/or the developers, can do it) add some tags to be sure than the movie is running on the Playback is in 4K,HDR,HDR10,DV(Dolby Vision),Dolby Atmos put it above the progress bar on the playback menu but somewhere more explicit instead of using the stats for nerds, just use something like(E.g Bellow) this but green like the emby theme, and something in the info to know than the movie is HDR, HDR10, Dolby Vision,Dolby Atmos, I guess (Not sure at 100%) than it only show 4K not HDR/HDR10/HDR10+ or even Dolby Vision, Dolby Atmos. 


Conclusion:

Add a tag/logo 4K,HDR,HDR10,DV(Dolby Vision),Atmos on the Movie UI (On the Playback menu "where you have that progress bar,parameters etc. *image bellow ")  
Grab the Info on the Media Info like HDR,HDR10,HDR10+,DV(Dolby Vision),Dolby Atmos (No logo needed at this part)
Add Filter for HDR,HDR10,HDR10+,DV(Dolby Vision),Dolby Atmos.

This is an e.g about that tag/logo for i request also for 4K,HDR,HDR10,DV(Dolby Vision),Atmos

 

 

Regards i will try to keep and try to update this post when the exoplayer get merged something regarding the Dolby Vision

Edit: I'm not able to put Dolby Vision Single Layer on Mastroka format with my build (But some users have done it already with the codec MpegH HEVC Main10@L5.1 (dvhe.07.06 BL+EL+RPU FEL) so it's possible allready i guess

@ebr Could you be more specific? Who hasn't brought it in yet? Isn't that gitHub post for the exoplayer? Seems like they did add it to the explayer. Or do you mean Emby doesn't yet have the exoplayer version that includes the DV add-in?

That is a GitHub "pull request".  That means it is an enhancement contributed by someone other than the Google developers.  In order for it to actually end up in the product (Exoplayer) the Google devs need to "merge" it into the code base and then release a new version with that in it.

It looks like they will do that, but they haven't yet.

It not part of ffmpeg yet.  It's an untested patch so far and not part of the main build yet.

any update on this? it will be great if we can have"dolby vision" showed in info label instead of general HDR

[Luke 36997]

We'll take a look at it. Thanks for reporting.

Are you able to clarify where / how I can find which version of ExoPlayer Emby on a Nvidia Shield is using please?

I can see from the ExoPlayer release notes that v2.12.0 support Dolby Vision using a MKV container, and not sure if Emby has it packaged with the app or its used from the Shields Android OS.

Many thanks

According Emby for Android TV beta release notes, this is the most recent version with Exoplayer changes. If a newer version of Exoplayer is used, it has not been documented in release notes:

Quote

...

1.8.31

• Add HDR info
• Fix missing people on subsequent item playback
• Improve refresh of global favorites view
• Update Exo to 2.11.8 (Google only)

Emby for Android (aka ET for Android) does support Dolby Vision in MKV container, you can test it:

Thanks @vdatanet for the info.

Emby for Android, does indeed work with Dolby Vision, I tested on my Shield.

Emby for Android TV on the other-hand doesn't, yet. Therefore, may I request that the ExoPlayer be updated to v2.12.0 please?

There are some things blocking us from doing that right now but, hopefully, in the next beta round.

@ebr Could you help figure out why DV isn't working on a Sony TV before releasing? DV works with Plex on Sony TV, but Emby doesn't. There is either no color or too much red.

Feature request:

Convert Dual Layer to Single layer on the fly (Please consider than some people like me disable transcoding to force people to watch the 4K contetnt without transcoing or downgrade on image resolution or making it not HDR, so please make this feature as allow or disable as a single part and not as part of a transcoding process) for tv doesn't support like said before 
example LG C9 support at this moment only single layer (but looks like the app from lg store doesn't support also single layer this give some green bizarre image) so hoping this will be fixed on the next app release, since single layer is acceptable in USB and by Plex (So please consider looking that issue), the feature will be making dual layer to an single layer dolby vision (mp4 or mkv) if required by the app (TV,Android Box, Mobile,Apple TV etc...) 
 

please consider this issue you can get the info about my testes done before.
 

 

in those two post there are Dual Layer & Single Layer info about movies in MP4 and the latest one post is mp4 single layer DoVision
HDR10 works fine mkv mp4 but still massive dolby vision improvement in cross platform TV/ APP/ etc..

Kind regards

Hi. I believe tone-mapping (already in beta) is going to be the solution here.  To actually "convert" any form of DV to another is likely not going to be possible as that is a proprietary format.
