Dolby Vision Profile 8.4 HLG fallback Vero V

Feature Requests

I’m enjoying the new Dolby Vision capabilities on my Vero V and I was trying to Play a FIFA world Cup 26 Match with Dolby Vision 8.4 (HLG compatible) but saw it only played in HLG and Not in DV.

I saw in the documentation, that this is expected, but it would be really nice if that was possible to Play in DV too (if possible).

If needed i’m Happy to Provider logs, Mediainfo, Samples.

Thanks!

Dolby Vision converts HLG to HDR10 because VS10 is designed to work from HDR10 (or SDR). Since we don’t have access to VS10 there’s no point in doing any conversion from HLG. You would just get a HLG->HDR10 conversion with no dynamic metadata. No different from HLG.

Just enjoy the football!

I might be mistaken, but I assumed, that Profile 8.4 contains dynamic metadata that is lost when just HLG is displayed? So that’s why I’m confused as to why it has something to do with VS10, isn’t that just for usecases where the display can’t handle Dolby Vision?

OK. You’re right. I’ve only encountered this format as iPhone footage and not given it much time. What is the source of that World Cup match? Online or broadcast?

The source Is web streaming.

Hi

Hopefully the issue is now addressed.

I’d appreciate it if you could test this and provide feedback before we potentially release this as an update to other users. To test this update:

DO THIS FIRST OSMC update issues solution then:

  1. Login via the command line
  2. Run the following command to add the staging repository:
    echo 'deb http://apt.osmc.tv bullseye-devel main' | sudo tee /etc/apt/sources.list.d/osmc-devel.list
  3. Go to My OSMC → Updater → Manual Controls → and select Check for Updates now. When prompted to do so on screen, please choose to install the update.
  4. Your system should have have received the update.

Please see if the issue is resolved.

I also recommend you remove /etc/apt/sources.list.d/osmc-devel.list after updating.

This will deactivate the staging repository. You can do so with the following command:
sudo rm /etc/apt/sources.list.d/osmc-devel.list.

Please note that we will automatically disable this update channel after 14 days on your device in case you forget to do so to ensure that your system reverts to the stable update channel.

Thanks for including this!

It works as expected, but I did notice, that when playing any Dolby Vision Content and e.g. changing the audio track the UI is noticeable slow, which might be expected for a unstable built?
