Non-Rec.709 video has wrong colors/saturation


Can you chuck me:

  • cat /sys/class/amhdmitx/amhdmitx0/edid
  • cat /sys/class/amhdmitx/amhdmitx0/disp_cap
  • cat /sys/class/amhdmitx/amhdmitx0/hdr_cap

So I can see kernel interpretation of your EDID.

So, if I understand correctly:

  • BD rips as-is that are non UHD are OK
  • BD rips that are expected to be Rec2020 (not yet confirmed) are problematic.

So the issue is with 2020.

That’s correct. Conversion should take place by default now.
There isn’t an exact science to conversion unfortunately, but there is room for improvement.

They should be persistent. If you switch mode in a significant way, you could see changes. If you kept playing the same set of demo clips, all encoded as HDR, you should be able to iterate easily enough.

No fixed approach yet. To be honest – I think experience varies across displays. A set of aggressively tested presets configurable via Kodi will probably be the way to go. I know the SoC vendor (AML) have some improvements in the pipeline; so we’re also looking forward to their improvements
