My device is ugoos am6b plus 2021, and the system is corelec 21 alpha2 ng-dv. I have found two bugs so far: one is that the bluetooth remote needs to be re-paired after powering off the device, and the other is that the dolby vision is only working properly on some mp4 videos, and other mkv video formats are not playing properly.And, coreelec backup data cannot be restored.

The Dolby Vision version of corelec 20 ng-dv can also be activated, but it cannot be mapped normally

Use “Amlogic-ng-dv”!

There does no nightly exist yet. Use CE-21 Amlogic-ng-dv until 20.3 release.

Thanks.CE-20.3 Amlogic-ng-dv 2023.08.09 or Use CE-21 Amlogic-ng-dv can only light up the Dolby field of view, but cannot map colors properly, as reported above.
It is said that CE-21 Amlogic ng dv has stopped updating?
Is the 922x-j chip rebuilding the NE kernel?
Is Amlogic-ng-dv and Amlogic-ng merging?
