Ugoos AM6B+, can't get it working properly

It’s hard to follow you guys :slight_smile:

I don’t know when a joke or real are writing, so yes, I’m for next Kodi (22) version so CE-NO, still, the nightly build on android works pretty good (with default skin).

But here, it’s not only Kodi, it’s the kernel change, right ?

if kernel was not to update Kodi 22 could be implemented in CE-NG where DV works (I mean DV FEL etc.) right ? (I don’t say that it’s must be the case, but to follow)

It’s my understanding, but I could be wrong here, for noob and maybe language barrier, some answer looks hard.

So yes, for me Kodi official nightly (based on my use) is really stable, so it should be stable here too, only the diff is related to kernel and hardware platform and Linux drivers etc.

I would like just to be able to have LLDV on my side LOL with latest nightly Kodi :smiley:
But CE-NG seems to work good from my reading and I hope CE-NO could be the same and for it, it’s needed to test build on product and report bug, but as a noob, maybe some report bug, is like an idiot bug

KODI ist just the application.
But You need an OS to run it.

You can use Android, Windows, MacOS, Linux and some special lightweight OS based on Linux like COREelec.

There is a lifecycle, but not only the KODI app.

Was never a problem until amlogic made a “fault” in kernel 4.9 and enabled DV-FEL, it was unintentionally.

Special case, very easy to understand

Just received my AMB6+ and on a fresh install and get the same message :slight_smile:

Copying the correct dovi.ko and the message is gone, still, I can’t enable “Always HDR” like the FireTV does to have LLDV with the vertex, and this box can’t play some video after all.

With NO, no FEL, with NG there is FEL but crash on some video HDR/DV.

Finally, it act like the Dune 4K Pro Vision, except that I was able to setup the remote in BT and/or IR :slight_smile:

How did you set the VS Engine ? (Can you enable LLDV as always ?)

Thanks

Thanks, I will do like you explain, because effectively, I have many bug and not stable at all NG or NO compared to FireTV 4k Stick, it’s disappointing but if I didn’t set correctly, it’s my fault.

Will do that ASAP and report back :wink:

There’s nothing wrong with NG.

No crashes at all and doesn’t matter which skin you’re using. My am6b+ running 24/7 without issue for months..

Nice for you, on my side, there is issue when refresh is trigger and when DV is active, my Epson projector has a long delay for handshake and then even with same fps, it always starts to init refresh rate, and after it’s DV, each handcheck is 10 to 15 seconds (start and stop) it’s a no go.

FireTV is working better on this.

Still, CE-NO has fixed the refresh rate issue compared to NG.

So I would have to never bought an Ugoos, even CE doesn’t work for my need, it’s too bad, if we didn’t get into such handcheck issue, it will be better yes, even if sometimes I have a weird color on screen, never with FireTV, and it happen NO and NG (official build).

So when testing on my Samsun TV, the handcheck is so fast, around 1 second, it’s ok for TV even if sometimes here also, strange color randomly, a restart of movie fix it sometimes somehow.

I don’t know if it’s related to Android for FireTV, but It works really better, only blank screen if refresh rate is different and not when it’s the same (fixe on NO) and when using always HDR (along with the vertex2 to add DV custom) FireTV is always on LLDV and color is good and starting fast ans Stop fast.

So I can’t tell that is great because it’s not, but I assume on TV and without refresh rate, it should works yes

So you answered your own question.

Get better projector.

There’s no better player available on the market than am6b+/minix/firecube with CE NG, period.

Many ppl told you so already and not only here.

10

Got better projector, you give me money :slight_smile:

Joke apart, Epson is excellent but yes this timing sucks, other DLPs (I did try a lot before bought Epson), I’m sensitive to rainbow effect, so it’s a no-go, if you are sensitive, you will understand that, and Sony or JVC (maybe the timing is long I don’t know) is too high at price and surely never be compatible to Dolby Vision even at 25K€.

NG has bug for sure, why doing a trigger of resolution change when it’s not needed ? (but it’s fixed on NO)

And yes, DV need some negotiation trigger (on the player side at least) that lead to this delay.
And this is maybe related to DV mode (player Led) but sometimes the image are not correct, like a lot star on it when looks like black and white. Or when back to the GUI, it’s purple.

Those kinds of glitch/bug, I can’t tell it works perfectly.
But I suppose based on different display, it didn’t happen, but I have seen on it on 3 :

  • Epson EH-12000B
  • Samsung 4K
  • Hisense compatible DV

And I can’t force always LLDV with CE-NG like FireTV 4K latest gen does (here need the Vertex2 to tell player that the display is compatible DV for Epson and Samsung)

So when, all is fine, that not true, even if in some configuration, bug are not triggered probably.

So you say no is more stable than ng?
Which one better in framerate and tonemapping?
As you got soc 922 and 928 soc which one is better in movies and how?

12

NO is more stable about refresh rate change from what I have seen.
On NG, it triggers the refresh rate when movie are in 23.976, if it triggers movie1 (23.976), when start again movie1 it’s ok.
I start movie2 (23.976 or close too?) it triggers again, if I start movie2 it’s ok, If I start again movie1 it trigger VRR.
On NO, like this movie1 and movie2 are the same, it stay at 23.976, so something must be fixed in Kodi, CE or linux Kernel.

For framerate, I would say NO, for tonemapping surely NG that handle FEL etc. but still, there are not as stable as FireTV for sure on both.

I have AMB6+, the best device for CE !

The better is the FireTV for me avoid too many handshake (framerate) LLDV always ON and most of the sample is working but, no FEL.

This is on my Epson with a long delay when framerate is trigger or change in DV (dovi.ko).

On a TV Samsung or Hisense (DV compatible) the delay of switch is so fast compared to projector, that is less problematic even if sometimes when return to the GUI, color are wrong NG or NO.

In fact, I don’t understand people say that it is perfect sorry, there is surely some glitch !

Its perfect, for dv compatible hardware chain and CE NG.

Your problem is not the box or the os, but the incompatible hardware, was you try forcing.

You just buy one dv licenced TV or projector. Or just use your firestick, and sell the amb6+.

I just cannot (under)stand people with DV incompatible hardware that constantly complain about CE-DV handling on such combinations. How difficult is to understand that it needs complete DV compatible chain to work without any problems as intended?

It makes me wonder just how stupid one has to be to mix diesel with gasoline and then constantly complain that the engine does not work OK?

Because on a hardware fully compatible with DV, like Hisense TV licensed with DV, it’s the same !

So for no compatible DV, you can use a Vertex2 or something similar, and it acts like a DV (Player Led LLVD).

Like does the FireTV directly on the Hisense (DV compatible) and with a Vertex2 for other and with Ugoos, you can’t achieve this !

So yes, need to try to sell it, you are right !

But nagging that with correct hardware it works, nope, there is the handshake trigger etc. on TV compatible or not, it’s fast, so you surely don’t even notice it, so yes it works but not perfectly.

I’m sure on projector DV compatible, there is a delay where it shouldn’t happen, and it’s here the issue, because on projector, this delay is higher than a TV.

If Ugoos will be able to do like FireTV, so reducing handshake only when necessary, it will be OK

Btw, when or look at projector reference, there is no DV (JVC, Sony, Epson…), you can find DV on china hardware yes, there is surely a reason, still, please don’t tell that the Epson is not a good projector, because in LLDV with FireTV, it does good result, too bad again, that, it didn’t work for Ugoos.

One person with 1000 problems and 1000 persons with working thing …. wondering where the issue is :laughing:

:wink: yep, will be nice to see how you will reply if you use FireTV instead and explain why it works (not for all FEL etc. ofc) but more stable about refresh rate and handshake DV.

Like it happens also in a full chain DV but on TV, I agree, that is less visible, but that’s not mean it’s nor present, still, I didn’t have 1000 issues but only 2, is already enough.

After, if having such is not a problem for 1000 persons, that’s Ok, but in final, if someone found the thread, it can help, if the person is sensible with handshake 10 to 15 seconds on start and stop video !

18

But that amazing that no one notice this, even if on TV, it’s faster !

19

No, it’s Not. On my Hisense TV AM6B+ with CE 21.2-NG, DV (P5, P7FEL/MEL, P8.1) works perfectly!!!

To add, FR and resolution switching works instantly; also picture quality not comperable with inferior on Fire 4k TV sticks…

Can you screen your settings please ?
I would like to try again on my Hisense TV :+1:
Thanks.

PS : And yes, on TV the switching is faster even if it shouldn’t do it from the same frame rate of different movies, when it’s fast, it’s OK, still this issue is fixed on NO.

It’s too bad, that we can’t reduce the switching for other display, to keep the GUI instead of switching back too ….
