DV profile 5 shows white screen on one show only

Help and Support Vero V
1

Hi team.

Somone else mentioned the same issue in someone elses thread, which went unnoticed.

Most DV content plays fine for me. But one show the video is white, sound is good. Same issue with Nov25/May26 version. As a side note each EP of the HDR version will cause Vero to reload around 75% through, I then carry on and its fine.

Sample can be found sample.mkv

That sample is Profile 5. Did you upload the correct version?

I misread mkvinfo, file is correct.

4

I can reproduce the whiteness here. Investigating …

5

Ah, I’m just catching up. Thanks for investigating.

6

Is yours the same series, then? What is the source?

7

Same series. Source is probably not something you’d want to discuss here! :wink: :rofl:

8

I’m only interested because Apple use DV in weird ways.

9

Amazon Prime in this case, I think.

10

Yes. The show is the male version of “the girls”. Fun quiz Thursday night at OSMC!

I have the same issue, in my case it is a combined dv.hdr version of the same show, the video is profile 8.06
I have an older LG C8 OLED, which was important information in the past. Before the update they played fine and if I force HDR (disable DV) I get a picture. All other DV and dv.hdr videos I have tried have played perfectly.

From MediaInfo of the file.

2160p.AMZN.WEB-DL.DDP5.1.Atmos.DV.HDR.H.265-FLUX

Dolby Vision, Version 1.0, Profile 8.1, dvhe.08.06, BL+RPU, no metadata compression, HDR10 compatible / SMPTE ST 2094 App 4, Version HDR10+ Profile B, HDR10+ Profile B compatible

FYI This isn’t the first time I’ve had an issue with a DV/HDR10+ fallback video, DV/HDR10 have been historically fine.

The DV FEL test video displays the woman at the 80 second mark.

Would a sample be of any use given you can already reproduce it with a profile 5 sample?

A fix for this has been developed. I’m not sure if it’s yet made it to the staging repo. Instructions will follow when it’s ready.

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:

  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.

Yes, that seems to have fixed the problem. A file that was formerly white screen is playing perfectly now. Thank you!
