Na, you use two libCEC devices on one Panasonic TV. Both are changing their address to 0x4 after polling the next free address. So both have the same address after the TV type get detected. At CEC there is only single address allowed on the bus. Again, I think you have to address this issue at libCEC repo.
After tests I did for me as the end user issue is simple:
- Using C2 running LibreELEC community build 8.2.3.1-C2 (libCEC 4.0.2) --> Denon AVR --> OLED Panasonic TV: CEC works properly.
- and when I had Minix_NEO_U9-H running LibreELEC-S912.arm-8.2.4.1.force.444.10bit.img --> Denon AVR --> OLED Panasonic TV: CEC worked properly.
- Using C2 running CoreELEC stable 9.02 --> Denon AVR --> OLED Panasonic TV: CEC doesnāt work simply do not responding for remote keystrokes.
- Using N2 running CoreELEC nightly 20190607 --> Denon AVR --> OLED Panasonic TV: CEC doesnāt work simply do not responding for remote keystrokes.
It looks like something is wrong with libCEC 4.0.4 implemented in CoreELEC or something is wrong with CoreELEC itself.
Yes, probably you are right.
Iām not technician nor developer so forgive me a noob question but is it possible to compile latest nightly build for N2 but with older libCEC library so I would be able to test?
I can do you a image next week.
Perfect! Appreciateā¦ Do you want me to ping you? -
In the meantime I will connect my C2 and N2 with CoreELEC and check how it will behave with another TVs and of course will report hereā¦
Thanks @Portisch in advanceā¦
Unfortunately, InputStream Adaptive is only available in version 2.3.19.1 in the CoreELEC Repo, although peak3d has already released version 2.3.21.1.
@mark-aus-51 unless one of us goes looking or someone tells us that there is a new version then we donāt know, I updated it 3 days ago and since then it has gone up another 2 versions.
The new version has been uploaded.
I was having similar issues as rabaraf with my Panasonic TV (connected via Onkyo AVR). Sometimes it worked but more often than not button presses simply didnāt work at all.
CEC in this test build seems to be working much more reliably than the standard build. Not perfect (lost CEC at one point after switching to TVās internal tuner and back) but after a reboot I havenāt been able to break it despite multiple source switches. Also my play/stop/pause etc buttons work in this build when they didnāt in the standard build. Seems like there may be a regression for Panasonic TVs in recent versions of libCEC?
I do have a persisting bug where when ādevices to power off during shutdownā is enabled, the N2 turns off my AVR (not the TV) around 5 seconds after booting Kodi.
Edit: play/pause etc have stopped working again. I hate CECā¦ itās slippery, so hard to nail down when itās working and when itās not.
Overall things are better but not perfect with this build. Here is a log in case itās helpful. http://ix.io/1Lis
About CEC. On 3.14 I originally made the cec driver to work in a hybrid mode. You had the kernel input driver that was independent from libcec. And there was the libcec mode. When I disabled kernel input driver because I thought nobody used it a lot of issues started.
Which now makes me think that those having issues now is because we donāt have the input mode and libcec is buggy.
Did you also try this test version?

Guys,
I spent almost whole night testing all things what comes to my mind.
Devel build what @TheCoolest compiled for me (libCEC 4.0.1) (Thanks for your time you spent on that) did not solved the issue, so version is not the root cause.
Then I prepared new microSD with nightly 20190603 and CEC was working. Then gradually I was adding addons checking if CEC still works in different scenarios (TV off/on, TV source selection TV/HDMI , AVR off/on, switching TV while watching something, etcā¦) always CEC was workingā¦ so I was so satisfied.
Finally I changed CEC Adapter settings changing them to my needs which are:
Enabled - on
Switch source to this device on startup - off
Devices to power on during startup - None
Devices to power off during startup - None
Send āInactive sourceā command on shutdown - off
Put devices in standby mode when activating the screensaver - off
Wake devices deactivating the screensaver - off
When the TV is switched off - Ignore
Devices to also put in standby mode - off
Use the TVās language setting - off
Action when switching to another source - Pause Playback
Physical address (overrules HDMI port) - 0
Force AVR to wake up when Kodi is activated - off
Remote button press delay before repeating (ms) - 600
Remote button press repeat rate (ms) - 20
Remote button press release time (ms) - 150
and thenā¦ CEC stopped working!
So I thought it has something to do with those settings.
Finally withe the following settings:
Enabled - on
Switch source to this device on startup - on
Devices to power on during startup - None
Devices to power off during startup - None
Send āInactive sourceā command on shutdown - on
Put devices in standby mode when activating the screensaver - off
Wake devices deactivating the screensaver - on
When the TV is switched off - Ignore
Devices to also put in standby mode - on
Use the TVās language setting - off
Action when switching to another source - None
Physical address (overrules HDMI port) - 0
Force AVR to wake up when Kodi is activated - off
Remote button press delay before repeating (ms) - 300
Remote button press repeat rate (ms) - 20
Remote button press release time (ms) - 150
everything with CEC is OK except with one small issue: after N2 reboot 4 buttons do not respond: Stop, Pause, Next (>>|) and Previous (|<<) but powering off and on TV while HDMI 2 (N2) is active source brings back those buttons functionalities.
As CEC works now in all scenarios mentioned above I would not touch anything in order to not break running system 
I donāt know if next nightly builds after 20190603 are having some CEC components modifications so Iām a little bit scared to perform upgrade to 20190608
And one thing broke down:
for most 4K movies there is no video signal at all. Example: https://4kmedia.org/ultra-hd-hdr-samsung-4k-demo-wonderland/ --> dispinfo result: http://ix.io/1Lix
but this 4K video is properly displayed: https://4kmedia.org/sony-mont-blanc-hdr-uhd-4k-demo/ --> dispinfo result: http://ix.io/1Liy
Now that makes sense. If you donāt set active source on startup it will not work.
Again on 3.14 kernel I made a kernel input mode and it always set source automatically.
But Iām happy it is resolved for you.
Does your AVR and TV support HDMI 2.0?
Because it looks like it canāt play 4k24p with 444 10bit which is not in the HDMI 1.4 spec.
TV for sure, Denon AVR-2200W - apparently yes as well as https://4kmedia.org/ultra-hd-hdr-samsung-4k-demo-wonderland was properly displayed yesterday with nightly 20190608 but I just did a check and connected N2 directly to TV and that demo movie was properly displayed so something wrong is with AVRā¦
Both demo videos looks similar in the terms of resolution, color depth, etcā¦ so why for the first is no video and the second is OK?

Arghhhhā¦ When I changed Kodi GUI resolution to 3840x2160 23,98 Hz I lost signal so this is reason. How to back GUI to 1980x1080 50 Hz while I see nothing on TVās screen?
Edit:
Connected directly to TV and set back GUI 1980x1080 50 Hz.
Whitelisted everything except 4096x2160 and 3840x2160p 23,98 Hz andā¦ EVERYTHING is OK.
Finallyā¦
Thanks to all for your time and supportā¦
You are doing amazing work hereā¦
