CE-NG Dolby Vision (+FEL) for DV-licensed SOCs (s905x2, s922x/z, s905x4)

And NO is alpha. NG is stable.
Even when no updates, still the best.
I have all three. NG, NE, NO.
When you not a tester, no reason to use NO.

All are EOL, choosing the best EOL through your own testing.

NG and NE are EOL. There won’t be much fixes anymore.

NG is old obsolete EOL 4.9 kernel like CSMC is using as they aren’t able to port the features to the new code base.

NE was only a placeholder with kernel 5.4 until NO was finished and is also already EOL.

CE-NO with kernel 5.15 is latest code base and the future. It’s mainly used since S5, S928X. It includes a lot of fixes, like audio sync issues, DV profile 10 support, fixed subtitle stutter, vp9 hdr10plus support and lot lot more, just to count some…

NO is running OK most of the time despite being build with kodi alpha. Some things will never gonna work.
Skins are not ready, subtitles behaving weird to name few…

It’s crashing from time to time but thanks to s928x kodi restarts instantly :grin: just opened temp folder and found 15 crash log zips since beginning of April…

Wish I had enough knowledge to rebuild NG to get it working with sk1.

When Amlogic do not invest a few hundred of thousand dollars NG will be never there. So the chance is below very low → never.

NG EOL is with SC2, S905X4. And even this SoC was not fully implemented.

All moan arround about ā€œalphaā€ status. It’s now even more stable and better working than 21.2 Omega. A ā€œreleaseā€ does not mean ā€œstableā€, it’s just a snapshot of nightly.

No log, no error, no issue to solve!

I know one kodi bug with CEC adapter, but only kodi crash on kodi stop. But this does not cause a reboot.

I’m not complaining :stuck_out_tongue_winking_eye: really appreciate all your time you guys put to this project. Being registered shortly but I’m a user from a very first days you split from LE. Can’t even imagine how tough your mind is and how much dedication you put into it.

ā€œWhen Amlogic do not invest a few hundred of thousand dollars NG will be never there. So the chance is below very low → never.ā€

I was sure you choose to build your project on a kodi version of your choice and you picked kodi 22.
Sorry if I blame you wrong.
Now I know it’s amlogic who made a choice and told you to use kodi 22 (despite being alpha) :grin:

Alright, no more jokes here :wink:

Kodi devs says >>

**Nightly Development Builds
Nightly builds are made on a daily basis and contain the most recent changes. These should be considered unstable for daily usage and should only be used by testers and advanced users to help us find possible bugs.

These builds may occassionally be unstable, so be sure to always backup before using a development/nightly build.

If you want a stable setup, then please install a stable build from the Recommended tab instead. **

And the only recommended build is kod 21.2

When I use CE-NG I do not get the pop up warning about DV not working because Android kernel is low version. But I get the warning in CE-NO :man_shrugging:

Does CE-NO nightly support FEL on Homatics?

No. Only CE-NG supports FEL, because there is no dovi.ko file with FEL support available for the newer 5.x kernels.

The CE NG fully support dv profiles, just use the right dovi.ko what linked in first post.

So does this also mean that we should not update ATV kernel to 5.X if we wish to install CE-NG and have FEL?

Please check the log at this link - https://paste.coreelec.org/BaptismTower

I can see the logos and the woman in the test video. The TV also shows Dolby Vision in the video settings during playback. I think its working.

Forgive me, I just entered the coreelec world yesterday: I would like to ask you where I can find the ā€œdovi.koā€ file for a s905w2, assuming it exists. I installed version 21.2 and both the remote and the display work, thanks to this wonderful forum. Thanks for the help.

The s905w2 is a newer SOC, there’s no support for it with CE-NG (kernel 4.9). Either use CE-NE (kernel 5.4) or CE-NO (kernel 5.15). Is your box DV licensed, does it play DV in Android? The dovi.ko only works with licensed SOCs.

Is DV hardly implemented? (i.e., it is present in bare S905x4, but not enabled, but in J, K variants it is enabled?)

Nobody really knows. My assumption is that all SOCs are manufactured with DV capabilities, then efuses are burned in factory to irreversibly disable features the vendor didn’t pay for.

Or, could it be the bootloader?
Or writing in a non-documented register?

AML has little control over the bootloader, especially on devices without verified boot enabled (devices most likely not to have DV). There’s documentation that indicates Dolby & DTS audio capabilities (and other SOC features) are disabled by factory set efuses. I don’t know why DV capabilities would be different, but anything’s possible.

Hello, it seems that hte dovi.ko file for s905x2 is not reachable.
Could someone please share it with me?

Thank you.

this might be relevant in a few years time, they got Dolby Vision FEL working on windows insider

I don’t think that helps Kodi as the only DV video playback API is only for UWP apps.

Competition is heating up in the windows space for ARM chips / Intel / AMD maybe mediatek+Nvidia
in a couple of years time, windows might be the only boxes selling FEL capable devices lol

also came across this

the 8440U is probably the best device if anyone is interested in Kodi on Windows. someone I know is in the process of buying this box and I’m interested in the performance, according to this

https://www.reddit.com/r/AMDLaptops/comments/1ee6jur/8840u_vs_8840hs/

The cooling solution on this is awesome too (same box has 54W rated chips while the 8840u is 28W rated), so can see it running 15W while Kodi is playing. and single core will be good enough that it beats a S9228X for kodi in windows even. anyway will be reporting the Python single core when he gets round in benchmarking it on the community sheet I’m updating.

Windows boxes will start to extend their performance lead , especially since AMlogic release a new chip every 4 years. The S928X isn’t that much better than the S922X released 5 years ago. Als ARM for windows will be competitive enough in a year or 2. Hope it spurs AMlogic to do more releases
