Dolby Vision and 1.15.1

[Cannikin]

Got a response from the MediaInfo author—Dolby Vision support in MKVs will hopefully be available in the next release! https://github.com/MediaArea/MediaInfo/ ... -677483293

[shawnc22]

Is there any way to change the DV profile level in MakeMKV?

You might be able to if you are familiar with a hex editor. It won't change the contents of the video file, just the DV metadata headers. This post here refers to mp4's but the process should be similar for mkvs as well:

Like I said in the other thread, the issue is with your set up. The files you're creating are clearly fine, especially if they're playing in DV with Plex, so I would suggest stop tinkering with the remux process and focus more on the set up. Have you tried any of the suggestions I had mentioned? Another thing you may want to try is just playing the mkv directly from the result of makemkv and see if atmos audio is working from that. If that doesn't work, then there's obviously something that's preventing atmos from being played. What does the rest of your system look like (brand/model of audio receiver, how everything is hooked up, etc)?

for now i think i'm just going to try focus on just getting the dolby vision part of the atmos doesnt work,you got a guide for that too aka ac3?

You, nor your file are wrong.. MXPlayer Pro uses Profiles 7 & 8 for DV. Your file is Profile 4 which only plays in HDR. After you change the Profile of your file, you'll have to refresh your movie folder(three dots in the top right corner) for MXPlayer Pro to play it correctly in DV.

[Cannikin]

Don't recall seeing this in the thread but there's an open Pull Request to add Dolby Vision support to ExoPlayer: https://github.com/google/ExoPlayer/pull/7667

We're so close! Right now it looks like the maintainer is waiting on the author of the PR to confirm that the included DV samples are public and can be open sourced.

Hey shawnc22,if you still have the apk that I sent you the other day (I deleted our conversation and I can no longer find the link) you can also upload it now!
This way you make everyone happy!
Thank you!

Sure of course. Here is the latest version of yusecope's modified ExoPlayer apk:

https://wetransfer.com/downloads/581a34 ... 917/ba7865

Please note that I have only tested short sample clips made from makemkv 1.15.2 and not a full length title. Also this has only been tested on the 2019 Shield Pro, so YMMV on other Android devices. And finally, all credit goes to yusecope and thanks again for the great work .

When I click the link it states 'transfer expired'. Anyone know where I can get the latest modded exoplayer apk. Thanks!

Hi, I have a very weird issue.

I re-ripped two of my titles and I get video with DV but a cracking noise instead of the audio.
I have the Shield 2019 Pro, with the previous method DV was working fine: TS and THD+AC3.
The problem is that somehow the receiver is getting PCM instead of DTS or Dolby Atmos.
I've tried from a pen drive and from Plex Kodi plugin. If I play the file from the Plex app I get the video in HDR10 with the same noise as Kodi. If I play it on the computer it works fine without DV: the receiver is showing Dolby Atmos with pass-through enabled.

Any advice, please?

[mazzetta86]

I uploaded a short video to show my problem.

When using Exoplayer of the 03/08 I get DV + PCM and weird sound. When using internal player I get HDR10 + DTS-HDMA but no weird sound.

I tested my setup with the previous TS method so, in theory, it's not an hardware issue. The Exoplayer test files work perfectly fine.

Dolby Vision support has been added to ExoPlayer!! https://github.com/google/ExoPlayer/pul ... -680168520

Now how do we get Plex to merge this?

Plex uses ffmpeg primarily, so Exoplayer is only for format support on Android. We rarely see plex doing features for one platform only

[Epedemic]

Shield 8.2 update is out. Anyone with the proper insight able to check if the DV color issues is gone, now that they've removed the bt2020 flag from DV?

Ahhh most of the threads always talk about a custom version of ExoPlayer "unlocking" DV in Plex on the Shield (or at least the Plex plugin for Kodi). What would be needed to support DV in the official Plex app on the Shield?

[jayper]

Plex is not really part of the formula, yet. Kodi is currently used, as it allows for the selection of an external player. Which is a custom version of ExoPlayer which was created by a member of the forums here.

Probably best to not spam the Plex Github with issues. That'll only upset the development team. There's a feature request space in the Plex forums, and there is a long thread asking for Vision support. Posting there is far more appropriate.
