Fake tv-led scenes with the sun shining bright looks blown out. Very noticeable on transformers the last knight.
Resume doesnt work with some movies on the latest CE-21. No issue on CE-20.5 for the same movies.
I think there is still some issue with the OSD during playback. Will capture a log tomorrow, but I noticed it tonight on certain HDR films like Casino.
As soon as OSD appears and disappears, video playback starts stuttering.
Don’t look now, but Kodi 21.0 Omega GA upstream just released!
You could test with Max Max Fury Road. It has 9919 nits.
Hi, am new to this forum and new to the Ugoos AM6B+ (just got it today). Please be nice to me as I am old and dumb 
Been following this thread for a few days but still got so many questions on how to install CoreElec for this Ugoos.
I guess the first one is now with the release of this new 21.0-Omega does this mean I should use this new release as my first attempt to put in on an SD card with rufus? And also does this mean that I still need or do not need to put that dovi.ko file on there too? (That’s talked about here : CE-NG Dolby Vision for G12 boxes (u22xj, am6+, firetv cube))
Like I might have implied, I don’t know yet exactly what to do. Am hoping to learn quickly though. Thanks guys
The latest nightly with 21.0 Omega is not yet available. You still need to download the latest nightly from CoreELEC nightly builds.
Yes, you still need to download and place the dovi.ko in the root of your flash drive after you flash it with rufus.
Search this for “Chroma Weight”
Just wanted to followup on a quick question:
If I want to switch from one firmware version to another, do I simply drop the new firmware in the update folder on coreelec, and reboot? If so, can I upgrade/downgrade at will with this method?

Hi Astrotrain, thanks for your reply but am confused. So what is that new Omega release that got PurplePlayer all excited about if it’s not for the Ugoos (which is what this thread is about)? I just want to learn…
I noticed one thing today - 1080p videos are upscaled to 4k when the GUI resolution is set to 4K.
GUI resolution = 4K:
- 4K video = 4k output
- 1080p video = 4k output
GUI resolution = 1080p:
- 4K video = 4k output
- 1080p video = 1080p output
1080p videos should be outputed at native resolution, even if the GUI has 4k resolution, shouldn’t it?
Are there any downsides (regarding DV video playback) from setting the GUI resolution to 1080p in conjunction with a 4k TV?
21 Omega nightly builds couldn’t play some DV FEL files correctly until the last couple releases.
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.
Unfortunately, whitelisting supposedly causes problems with DV playback
I’m sure that’s something the devs will look into sooner or later once the basics are working properly.
I think this has been fixed now.
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

It seems there can be some issues with the network card, I have a box that is very finerky with it also
Thread here about it
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.
Wow that’s 3 people with this issue (including me - I had a box I sent back because of this issue). I wonder if Ugoos had a bad batch…
