CoreELEC 19.4-Matrix_rc3 Discussion

I noticed an interesting shimmering effect when playing VC-1 content. The sample includes two clips from Harry Potter and the Half Blood Prince. It should be able to be seen on the stair steps and the rocks. Odroid N2+ 4GB

Logs: http://ix.io/3Qze

If someone would like to have a look, I have a dmesg output of the sudden CEC wakeup. It starts with:

[12022.870475@2]- audit: type=1701 audit(1645710747.618:2): auid=4294967295 uid=0 gid=0 ses=4294967295 subj=kernel pid=3573 comm="LanguageInvoker" exe="/usr/lib/kodi/kodi.bin" sig=11

The TV turned on, but I can only see black screen, no KODI menu, no reaction to any input, except of an X11 mouse pointer moving within a small area in the top left corner of the screen when there is a mouse input movement. Behind this small area it just disappears. Can I have a look at something else? No more logs I could find.

With rc2+rc3 i have no picture with 4k movies on 1080p beamer, all resolutions are whitelisted. Back on rc1 and all works fine. Coreelec runs on Odroid N2. Script.skin.helper.service is deactivated, it was a clean install with rc2, then a clean install with rc3, result, no picture with beamer, with tv i have picture (with and without hdmi splitter).What the hell?

In log it sees 4k resolution with 59.94 and 60 Hz on that it tries to playback video.
If you projector is 1080p only then it shouldn’t see 4k resolution.
So you got wrong resolution on start from somewhere.
For such issue both dmesg and kodi log required.

@boot2k3
I downgraded to rc1, this weekend I want to watch movies. It was my mistake to think stable is stable…
I will update to rc3 maybe next week.

Edit: And yes, my projector is 1080p, but this was never a problem, only with rc2 and rc3. With rc1 and ALL older releases, works 4k on this projector (down scaled to 1080p).

Sorry for get back to u this late, it has been a hell of a week
Anyway, IT FINALLY WORKED!!!
Thanks a lot!!!

Did it work correctly before in 19.3 or earlier?
VC1 is specific old format

Yes, I just put 19.3 back on to test. Works great.
Just wanted to put the observation out there.
The format is ancient, so it’s not really important.

Beelink GT King Pro with Coreelec KODI the screen darkens when the movie starts and the TV shows that there is no signal, the same when the movie starts and I give a stop … I forgive my English, I use Google translator, I use … CoreELEC-Amlogic-ng.arm -19.4-Matrix_rc3-Generic in Android 9 is all OK.

Should be fixed in current nightly.

“Minix Neo T5” will restart right after the initial MINIX string in the loop.
I checked all the night versions. Build 20220110 → OK, Build 20220112 → Not OK. Probably the problem with booting the system from the SD card was caused by some new function introduced in Build 20220112

82212bb1a1: Mon Oct 11 14:59:02 2021 +0200 - Amlogic-ng: rework display mode to use 'vout' 'hdmimode' and 'cbsmode' got removed in 4.9.269
04a37e3506: Fri Oct  8 09:18:13 2021 +0200 - Amlogic-ng: adjust linux config for 4.9.269

Since these changes, no new version of CoreElec does not allow for a proper boot from an SD or USB card.

Did not work. Test with fresh install of current nightly, only addon is emby.

You need to select in whitelist all resolutions that you projector supports and exclude 2160p59.94Hz and 2160P60Hz that it reports as supported

Was running and working fine with 19.3 using gxl_p281_2g.dtb. However, I made the mistake and did the auto upgraded to 19.4 rc3. Now CE will not boot. It stuck on the console and never reached the CE bootimage. The error message “Error in mount_flash: mount_common: Could not mount LABEL=COREELEC”

@hieppo, you need to use nightly version where this problem is fixed.

Hi. I have installed the current version of CE on a Nexbox A95X with SD card.

Beside some reboot crashes while playing movies because of instable WiFi it works in general.

There is one issue I currently have no idea what to do. The Nexbox is connected to a Samsung QLED TV.
If I start the Box while the active TV HDMI channel is the box, it takes a minute and then I can see Kodi.
However if I start the box while the TV is on another HDMI channel and switch to the box channel later the TV says „no signal“ forever until I reboot the box again.

Any ideal?

@vpeter that did the trick, thanks.
