I just tested this and I can say it works on Ugoos AM6+

I tested also and it’s working on Ugoos AM6+, CE-NG 20.5

Thx, this will allow us to drop project Amlogic-ng-dv.
Does everything work? Like Fel?
Following on from Dolby Vision for Minix U22X-J (Max) and Ugoos AM6+ - #345 by doppingkoala
@YadaYada It is a X96 Max Plus device. I have never used the android, I’ll need to test that at a latter time. Is there another way to tell aside from testing in android? (which would then depend on the android/app code supporting it, not just physical device).
The cpu is listed as a S905X3-B in coreelec - not sure what the -B refers to. My hope was kinda based on the Chromecast with Google TV (4K) using a S905X3 cpu (haven’t found which variant) and supporting DV.
EDIT I was told that this is the DV check (in your dmesg):
dv capability 6
SOCs with DV ability return value 7, any other value means no DV support.
I didn’t find anything on Google indicating the X96 Max Plus has DV licensing, so I’m not sure. I don’t know how to check other than booting Android and trying to play a DV video there.
You can try using the dovi.ko from Sabrina (Chromcast s905D3). It has a better chance of compatibility. I only know of this website hosting the entire firmware that you can extract it from. I’d start by checking Android, it’s less work.
The display can be set to DV in uboot, CE needs to know the uboot DV state (on/off) which you see tracked in dmesg. Some of the other stuff is the amdolby_vision module included with CE, and some of that is the s905x2 dovi.ko being loaded.
DV capability is determined by the SOC, so if it’s not DV certified there’s nothing CE can do to make it play DV videos.
-B is dolby audio licensing
I have no success trying this on a SM1 device (S905X3) using NG-20.5.
Interestingly, there were lines referencing both g12 and the dovi module in the dmesg log:

I also found dolby_vision_on=0 in the kernel command line, and [ 0.000000@0]d get_dolby_on: 0 shortly after. The full dmesg log is here.
Few question for anyone that may have answers:
- Based on the log does anyone know if DV is possible on this box?
- Why is
dolby_vision_on=0in the kernel command line? Isget_dolby_on: 0related to that / can that be changed? - What is
dv capability 6? - Can
g12 dovi disable in ubootbe changed by altering the uboot? Would that be helpful?
May you try out this version if DV start playback now in CE?
How exactly do I use this? Do I put this in the update folder of my NG-20.5 install?
I only make CE-21 builds anymore. You will need to start with a spare boot media with CE-21 and then update with this test build.
That’s a cheap device with outdated Android. It’s highly unlikely to have DV support.
dv capability 6 means that the SoC does not have DV support. SoCs with DV support with have dv capability 7.
I’m just looking into how to do this hopefully I can use CE file manager.
So I’m currently in CE NG-DV I don’t have a /storage/dovi.ko folder. Would I need to make one or will it be there after updating to CE-NG.
dovi.ko is the file, and /storage/ is the destination folder.

Thank you, I think I’ll hold off updating at the moment as there is a lot going on.
try it , after seeking freezing few seconds, worse than ng-dv
What device?
What version of CE-NG-DV were you previously using?
What version of CE-NG did you try with the DoVi.ko?
ugoos am6b plus
20.5 ng-dv
the latest potish give me the test build. 21 ng omega
I know you have crossed it out based on finding that the dv capability should be 7, but I thought I’d test with the dovi.ko from the Sabrina link.
DV still doesn’t work, but changing the dovi.ko removed these lines
[ 12.075462@1]- dovi: module license 'AML' taints kernel.
[ 12.075464@1]- Disabling lock debugging due to kernel taint
Does that provide any insight?
20.5 ng-dv
the latest potish give me the test build. 21 ng omega
@jeffc3753 See if you experience the same freezing in CE-NG 20.5. That will help rule out any DV bugs in CE-21 being the cause.
@doppingkoala Did the build that Portisch created make a difference?
I was unable to test your build. When trying to update from CoreELEC-Amlogic-ng.arm-21.0-Omega_beta3-Generic.img, I got the message
Filesystem corruption has been detected!
To prevent an automatic repair attempt continuing,
press any key or power off you system within the next 120 seconds
In case it is helpful to anyone, when I had the CoreELEC-Amlogic-ng.arm-21.0-Omega_beta3-Generic.img running (before I tried the test update), I added the dovi.ko and the following portion of dmesg
[ 10.246138@2]- dovi: disagrees about version of symbol module_layout
