CoreELEC 19 Matrix Discussion (Kodi RC)

I would suggest a box with an S905X3 or better SoC.

I have the Minix Neo U1, so Iā€™m in the same boat as you.
From what Iā€™ve read, Iā€™d choose either the Odroid N2 (4 Gig RAM) or the Minix Neo U22-XJ. Both have the new S922 chipset. There is also the N2+ but that additional power would go to waste as the N2 is already more than powerful enough - or so I hear. The N2 would probably be the cheapest option.

Let me add a little to the information you have provided.
The Odroid-N2 is no longer produced, instead the N2 + is manufactured and on sale.

The U22 can do Dolby Vision but it has a bug that effects SD card booting. But with ceemmc it works quite well. If you donā€™t need Dolby Vision I would go with the N2+ or C4.

Can coreelec do dolby vision?

Dolby Vision is being worked on. Unfortunately getting it working is not as straight forward as getting other HDR formats working. Itā€™s a bit more complicated, less well documented plus there is some bs to do with licensing that is causing an extra headache for the developers to work around.

@cdu13a I have a ODROID N2 and planning to buy a LG OLED CX.
What can i aspect what HDR formats are working with coreelec?

And ive got a lot 1080p movies how is the upscaling is it better to do the tv or kodi the upscaling?
What resolution to choose for the coreelec gui with this tv?

Thanks!

once again tried new nightly, works smoothly until n2 restarts, than exactly same problem, kodi crashing when pvr.hts connecting to tvh. now i am sure itā€™s connected with pvr.hts and tvheadend communication. tried two tvheadends (v4.3), one installed on N2, one installed on ubuntu pc. no difference. hereinafter related parts of logs taken on N2 pvr.ht and ubuntu tvh.
ERROR : AddOnLog: pvr.hts: failed to send hello
ERROR : AddOnLog: pvr.hts: Command hello failed: failed to write to socket
ERROR : AddOnLog: pvr.hts: Command hello failed: failed to transmit

no problem on same tvh using ce 9.2.5.

@KodiKinG I would expect all the HDR formats that the TV supports except for Dolby Vision should be usable with the Odroid N2. The SoC in the N2 is not licensed for Dolby Vision, so even if we could get it working we couldnā€™t release support for Dolby Vision support on an unlicensed SoC without getting Dolby very upset.

As for the up-scaling, that might be something you will have to experiment with. The N2 does a reasonably good job with up-scaling, some TVs do a reasonably good job as well, some donā€™t. So it tends to come down to trying both and seeing which is more watchable for you.

Leaving the resolution of the gui in CoreELEC at 1080p and letting CoreELEC change the resolution for playback when needed is usually preferred option. While the N2 is fast enough to do a good job at displaying a native 4k GUI, 1080p will always be that little bit smoother since itā€™s 4x less pixel for the system to be dealing with.

Hi, I own the CX 65. The N2 works fantastic with this TV. HDR works flawlessly - no problems. In my opinion, TV is better at upscaling 1080 to 4K.
GUI is set to 1080p.

Dolby Vision support would be great.
I understand that there is no chance of this with N2 or N2 +? So what device would I have to buy to possibly support DV and CoreELEC?

As far as I know it would be only Minix U22 from the official supplier list right now.

any way to disable pvr.ths addon from command line? canā€™t acess n2 from ui, it is in bootloop. can access from ssh for few seconds

I have the 65" CX and the N2+. I couldnā€™t be happier, to be totally honest. As sojer2005 already said, upscaling IMO is better handled by the TV.

It hasnā€™t mattered for my usage but the CX itself doesnā€™t support HDR10+.

Thanx for explanation bruh

Thnx for sharing!

Is any content with HDR10+ then?

Try this:

curl -s -H 'Content-Type: application/json' -d '{"jsonrpc":"2.0","method":"Addons.SetAddonEnabled","params":{"addonid":"pvr.hts","enabled":false},"id":1}' http://user:pass@127.0.0.1:8080/jsonrpc

You have to have webserver ā€œallow remote control via HTTPā€ enabled in services and substitute ā€œuser: passā€ for your combinarion

Or you disconnect the HDMI cable, power up the device and try to connect by SSH.
When connected type systemctl stop kodi.
Then you have time to remove the addon in /storage/.kodi/addons

Hello guys.
Thanks for your excellent work.
I have the latest matrix nightly installed on my s905x device (beelink mini mxIII II) and I have a little problem with the framerate.
It plays the movie when starting the device with the correct framerate 23,976. after stopping the movie and starting another one the framerate switch to 24. after restarting the device and starting the movie which was previously played with 24 hz the movie starts with the correct framerate 23,976 hz.
I did choose Different options in the framerate switch Settings (start stop / only start).
Did anyone had the same problem?
