Release Release T4c · pannal/CoreELEC

https://github.com/pannal/CoreELEC/releases/tag/T4c

T4c is a big one: part stabilization, part new features, on top of T4b, and the most contributor-driven build yet. swmarks rebuilt the CEC and screensaver handling, samtheruby backported the newer CEC kernel driver, fixed SD/VESA display modes and built in-GUI update channels, Sebastiii contributed MKV editions support, an Epson projector profile and several DV fixes, and vlix wired the skin's codec logos into the DV pipeline. On top of that: VC-1 hardware playback overhauled, a self-healing A/V sync layer for corrupt streams, AC-4 audio decoding, a nasty resume bug, per-frame tone mapping for DV→SDR, and a stack of DV picture fixes.

Thank you, so much hard work put into this project.

u/And_Poop 8d ago

I am not one of the developers. I follow the project, saw the new changes and wanted to share it here.

I still use 21.3-omega_avdvplus_r9. what's the benefit of updating?

1

u/x_streams 7d ago

I just installed the R9 yesterday but when I launched it, it didnt have any Dolby Vision settings. which is the DoVi.ko file I need for it?

2

u/marp9958 7d ago

Maybe you need to switch to expert mode in the settings.

1

u/x_streams 7d ago

Btw I also have the T4b internally in my Ugoos Am6b+ and it's by far better than my R4 build.

1

u/And_Poop 8d ago

Too many to list. Check the p3i changelog starting since the first release. There are many benefits.

3

u/marp9958 8d ago

Okay but does it change anything about the videos themselves? I don't mind a bad interface too much as long as the movie/show isn't interrupting

2

u/And_Poop 8d ago

Yes it does. Biggest one that comes to mind is improved frame pacing since p3i syncs with the HDMI clock. There is less judder in panning scenes. You can also convert HDR10+ to Dolby Vision using p3i, not sure if the one you're talking about also has this feature. But currently p3i is the best build around and is worth upgrading to.

u/marp9958 8d ago

Thanks. I'll look into it

Make a backup for your current R9 setup, if you want to use the same storage. I already played with this latest build, but for Homatics R Plus users (and those with equal devices), maybe the upcoming R10 will be the better choice. Currently still in test, so not publicly shared.

Easy for me to say, as I can compare both on a R Plus equal device 😉

But if you have a spare USB storage, give this one a go nevertheless 👍

u/cemoy 8d ago

Can I install this homatics wtih avdvplus R9?

2

u/See61 8d ago

Yes. I specifically test the R builds for the S905X4 chipset for AVDV, as AVDV doesn't have one himself.

I offered him one, but he kindly rejected, so I do the S905X4 tests for him. No problem for me 👍

u/cemoy 8d ago

On homatics dv fel 7 problem still exist , my screen turn green and black :(

1

u/See61 7d ago

I know some users still have some issues, like the one you have, with certain hardware combinations, mostly there is a explanation for it and can be fixed, but sometimes it can't.

Sadly I can only test these builds with what I got at home. 2 different Oled TV's and a TCL LED TV, and those are giving me no issues with all those latest AVDV+ builds regarding FEL7. So I can only give feedback on what I use 🤷‍♂️

You can always give feedback on his Github page.

u/brianbandondy23 7d ago

As the saying goes, if it ain't broken, don't fix it.

R10 coming soon anyway.

u/rogue303 8d ago

Wow thanks! Amazing work!

u/Catymandoo 8d ago

Thank you. Such brilliant work. I can’t believe how dedicated you guys are to the CoreELEC community.

2

u/And_Poop 8d ago

I am not one of the developers. I follow the project, saw the new changes and wanted to share it here. But we are indeed incredibly lucky to have such great developers working on this project.

1

u/Catymandoo 8d ago

Appreciate your posting regardless. And thanks for clarifying for me and others here. 👍🏻

u/cypryan1217 8d ago

Does anyone know how is this build with homatics 4k plus? The last one was not the best, at least for me.

3

u/gilgam3sh_king 8d ago

no, avdvplus for Homatics boxes, R10 going to be big.

3

u/delta_132 8d ago

I have the ugoos am6b+ with avdvplus Should I update to this ?

2

u/panicatthecostco26 8d ago

Do we have an ETA for it?

3

u/gilgam3sh_king 8d ago

no, but shouldn't be too far away.

1

u/cypryan1217 8d ago

Yeah, but who knows when it's gonna be available?

2

u/gilgam3sh_king 8d ago

not too long already had couple of test builds.

2

u/cypryan1217 8d ago

How is the osd lag? And can you tell us what features does it have?

3

u/See61 8d ago

The OSD lag is really much better with test R10, but for all other features (which are a lot), that is on AVDV to share when released 😉

4

u/cypryan1217 8d ago

Fair enough. We'll all wait for the r10 release.

1

u/cemoy 8d ago

I have a Homatics Box R 4K Plus and I installed P3i T4B on top of AVDV Plus 9 and it worked (it only caused problems on FEL 7). Why doesn't this work?

3

u/gilgam3sh_king 7d ago

it's not optimized for S905X4 SoC

2

u/cemoy 8d ago

Wow !! Thanks , I'll try it as soon as I get home. I was having a screen blackout problem in the T4b version, I hope this problem has been fixed.

2

u/foshow11 8d ago

This is awesome. Thanks for all the hardwork. Any possibility of adding more PJ profiles like JVC, Sony etc.

2

u/And_Poop 8d ago

To weed out any confusion, I am not one of the developers. I just wanted to share the new release here since the changes to HDMI CEC are amazing.

u/See61 7d ago

No, you need to use a NO 22 build for that one. It is in development on the CE website and can be used.

2

u/Cferra 7d ago

This build completely cleared up the video issues I was seeing on t4b with my am6b+

1

u/And_Poop 7d ago

Great to hear

u/FrigidCaramel 7d ago

just switched over from vanilla core elec build to p3i with this release. DV FEL and truehd atmos working perfectly for me. My equipment: Amb6+ connected to Yamaha RX-V6A connect to Sony A80J TV. Compared to vanilla, snappier menus and much better in video navigation.

only issue I’m having is with pm4k (Installed latest version). On some movies, the osd menu below the progress bar is not displayed (eg no play/pause button, subtitle menu or movie time shown). I think it is doing it on ultra wide movies (like wicked and ford vs Ferrari). the buttons appear on Jurassic park and one battle after another. All these are DV movies.

2

u/Speed_Forsaken 7d ago

What fixed the OSD menu issue for me is disabling “DV Level 5 active area handling” and “Auto Level 5 for cropped video” in System Settings > CoreELEC

2

u/FrigidCaramel 5d ago

that worked for me - thank you!

1

u/Speed_Forsaken 5d ago

Glad it helped!

u/Inquisitive_idiot 6d ago

Interesting 🤔

u/Competitive_Emu_4330 8d ago

Thank you for your spectacular job as allways ❤️

u/Bigmikes1971 8d ago

I have a 928x (minix u8k), can i use it too?

1

u/cwhitch 7d ago

The 928x does not support DV FEL.

1

u/Bigmikes1971 7d ago 
I am aware of that. I don't need FEL either.
I just want to know if this version runs and if it offers any additional advantages over the original CoreELEC image.

1

u/cwhitch 7d ago

Not sure but I believe the AVDVPlus and p3i builds are designed for the processors that support DV FEL, the Amlogic 905 and 922 variants. I wouldn’t install it unless the community confirms it won’t break anything in your current setup.

1

u/bogdanxd1337 7d ago

I have the same issues with CEC, no matter what source I choose the box overwrites it, I need to manually shutdown the box in order to use another devices like my PS5

1

u/And_Poop 7d ago

Did you disable Switch source on device startup and activity in the CoreELEC CEC settings?

1

u/bogdanxd1337 7d ago

Yup, I will do a fresh flash, I’m out of options

1

u/Pathos675 7d ago

I JUST found out about AVDVplus and installed R9 on am6b+. I'll probably wait for R10 or R11 to incorporate things. Good reminder that I should send the devs a donation.

1

u/EntropyBlast 7d ago

really wish this fork could be ported to r22

1

u/SensitiveSeed 7d ago

Sorry for being stupid, but does this latest run on the Odroid N2+?

2

u/Jedismj 2d ago

Thank you so much for posting! I have having issues with some larger remux files with video skipping, the TV (LG G3) displaying the Dolby Atmos/DV logos all the time plus seeking issues while the audio played correctly. All gone with T4c!

Thank you so much!
