Whitelisting can be used to avoid the upscaling by Kodi.
If the GUI resolution is 1080p, then anything less than 1080p is upscaled only up to 1080p. It means your display device may then upscale a second time to 4K which is not nice. It would be great if the GUI and actual display resolution could be adjusted independently.
am6b+. I have the latest 21 nightly running after having tried a couple of 20.5 and 21 builds. Currently running in dual boot but tried running off of the sd card too. Everything works great except the ethernet port is very buggy across builds. it wont even let me run iperf, but ethtool and “ip link show” reports a 1 gigabit link is up. movies freeze and stutter irrespective of bit rate/color space. on wifi i get ~500 mbps per iperf3. Any idea if the ethernet drivers are borked in this kernel? or maybe i just got bad hardware. its onew off of aliexpress
Running CE20.5 with dovi.ko here, on the Convert DV for compatibility options, I got: Lossless, Profile 8.1 MP, Profile 8.4, Profile 8.1, Minimal EL. Am I missing any option? Which one should I choose? By default I believe it was Profile 8.1, should I keep it? Change it Lossless? Thanks.
I used the busy screenshots and explained this was on the official dual boot firmware and I think as my first return on aliexpress it went through within 2 mins and a free return

Page 9:
Only profiles 4 and 7 have an EL layer. Also for profile 8 the only valid cross compatibility values are 1,2,4. Profile 7 is the only profile with 6. There’s what seems to be an encoding error in this mkv. And we shouldn’t expect coreelec to playback a flawed mkv file with encoding errors.
You’re mixing up Compatibility and Level ID. PurplePlayer is right, your file is muxed in a non-standard profile. see this explanation about levels and compatibility ID
Profile 8 is a single-layer format and cannot have an enhancement layer.
Mad max was made at the dawn of hdr and it’s not in DV. Weird science is made in DV and has peaks up to 10000. It makes sense to test on it. But I don’t think it makes sense to leave such bright details above 4000. I will check on it, but most likely it will lead to lower brightness of the rest of the image
Movies usually have L2/L8 trim passes manually crafted by the colorist which might restore any lost details. The patterns with clipping on the ugoos/x800m2 I shared are Level 1 metadata only. L2 Trims in Wierd Science are generated though(not manually crafted). It’s also a bad grade since the mastering display is 1000nits but has pixels well over 4000nits.
Yes, I firgured this was a specific issue with the file, though it was directly rippped from the disc. I wonder why this (invalid) combo trips up CE but not other players?
