Strong artefacts on x265 content

Help and Support Vero 4K / Vero 4K +
1

Hi everybody,

I got my Vero 4K+ yesterday and installed it. For almost one hour, everything worked great. After this tine it started to show strong artefacts on X265 4K content. I switched to another movie - the same. Today, it is not possible to play any 4K content without these artifacts.

Has anybody an idea? I would appreciate any help.

I guess it helps if you upload a picture showing what you see.
Also provide mediainfo from the file and a log file so we can see the capabilities your TV annouces.

It would be good if we could find out more about the file you are having issues playing. Please see the mediainfo section in How to submit a useful support request - General - OSMC.

You can also create the mediainfo-output of the affected media file on the OSMC device:

  1. login via SSH, user osmc, password osmc
  2. if not already installed: sudo apt-get update && sudo apt-get install mediainfo
  3. cdto the directory containing the video/audio material in question
  4. since mediainfoonly needs to read the header information of the file data, copy the first 4 Mbytes of the media file to a new file:
    dd if="<media file>" of=purgeme.bin bs=1024 count=4096
  5. upload the decoded media information using
    mediainfo -f purgeme.bin|paste-log
  6. publish the returned URL here in this topic
  7. remove the created media file snippet
    rm purgeme.bin

Thx for your help.

Hi,

I added the screenshots to my first post. These are the mediainfo files:

Another additional test result. With an original remux of the blu ray without reencoding, it is the same problem. It seems now to happen with any 4k content.

debug logs needed, please.

Are you playing 4k HDR content?
We need to see the logs as suggested.

Hi Graham,

thank you very much for your help.

Unfortunately, the new kernel did not solve my issue. I have installed kodi on my tv and my apple tv for testing. I noticed now, that also the wallpapers of the kodi gui on osmc have also artefacts (gui is running with 1920 x 1080 @60) . My “native” kodi installation on my tv looks good and also the kodi installation has perfect colors.

The Vero 4K+ is connected by a Denon AVR-X4400H to my Philips 55POS9002.

As a test, can you quickly run Vero 4K + directly to TV (and reboot) instead of via the AVR?

Done…unfortunately no change

Would you mind posting debug logs again, please? the test kernel has more messages.

Gladly, here they are:

I have also added a screenshot of my bootcreen. Here is also extreme blurring visible.

Start by setting your desktop to 1080p50Hz. That’s a workaround for a glitch in that kernel.

15

Thanks, did that. But no difference.

16

OK, there’s a new kernel cooking right now which should help.

17

You guys are great :v:

It should be ready now.

  1. Login via the command line
  2. Edit the file /etc/apt/sources.list
  3. Add the following line: deb http://apt.osmc.tv stretch-devel main
  4. Run the following commands to update: sudo apt-get update && sudo apt-get dist-upgrade && reboot
  5. Your system should have have received the update.

Please see if the issue is resolved.

I also recommend you edit /etc/apt/sources.list again and remove the line that you added after updating. This will return you to the normal update channel.
