Problem with resuming long paused video in Kodi using Flirc USB v2

[JeroenD]

Hi,

When I pause a video in Kodi for a long time (couple of minutes) then I cannot unpause/resume the video using my remote+Flirc.
It simply doesnot respond to the remote/Flirc anymore.
When that situation happens I use the iPhone app "Sybu Kodi" or I plugin a real keyboard to unpause/resume the video and that works, 
and after that Kodi responds to the remote/Flirc again as well.
Any idea what might be causing this issue?
Apart from this issue my remote+Flirc is working fine all the time.
Any help is much appreciated, thanks and regards,

Jeroen.

My system:

- Flirc USB v2, FW Version: v4.10.5
- Xbox One Media Remote
- LibreELEC 12.0.2 with Kodi (Omega) v21.2 (LegacyGenericPC)

I have also enabled Kodi debugging.

During normal operation when I press the play/pause button then the Kodi log file shows the following message:

2025-03-27 12:06:31.164 T:631975   debug <general>: HandleKey: play_pause (0xf0bd) pressed, window 12005, action is PlayPause

However when the video is in long pause (couple of minutes) then my Flirc is not responding anymore when I press a button and then this HandleKey debug message is NOT shown in the Kodi.log. 

Therefore I think this issue is a bug in the Flirc firmware.

What is the next step?

When this happens, can you ssh into it and see if there are any logs?

Do a `dmesg` paste that here.

Also run a few commands and see what happens.
 

flirc_util unit_test

flirc_util settings

Let me know. 

[JeroenD]

Hi Jason,

Thanks for looking into this.

Here is the output of the "dmesg" ==>

https://paste.libreelec.tv/funky-barnacle.log

Below are the outputs of the flirc_util settings, device_log, unit_test and settings. 
As you can see, after doing the unit_test my recorded keys are lost and I have to re-load them from my configuration file.

@jason ,

Any idea what might be causing the issue?

Do you need more logs / info? If so then please let me know what more you need.

Thanks.

This is really crazy. Does this happen every time?

I don’t see anything in dmesg. 

Can you do a flirc_utility device log before this happens and after it happens. I may need to send you some special firmware to get more logs. The only way a device can lose its memory is if it’s sent a special command. Or memory gets corrupted, and the way that happens is if something writes to memory… But it would also say in the device log if it found corrupt memory.

Are you doing anything custom like running the utility in the background or as a startup script, etc?

 

[JeroenD]

@jason,

 

This happens indeed every time I do a unit test.
I just repeated again following commands: device_log, settings, unit_test, settings, device_log.
As you can see below again my key recordings are lost.

I am not doing anything custom at all. I am not using the utility, not in background and not in script. I am happy to install the special firmware to get the extra logs (however you have to tell me how to install it, because normally I do this only with the GUI).

@jason, done.

[JeroenD]

@jason,

Today I received the new device, many thanks for that!

I recorded the keys and all works fine except that I still have the unpause video issue :-(

Also I performed a "flirc_util unit_test" with the new device and after that the key recordings are lost, same as with the old device.

In the Flirc Windows GUI, I reloaded the configuration, and retrieved the Device Log (selected from the File menu).

It says something about broken hashtable.  See below.

[jason]

Is this plugged directly into the machine?

[JeroenD]

No it is connected in a hub, because my machine has only USB-ports at the back.

[JeroenD]

@jason,

I have plugged the Flirc USB directly into my machine this time and run the same flirc_util commands.

However it doesn't make a difference. After doing a unit_test the recorded keys are still lost again, and I have to reload them in the Flirc GUI.

When I retrieve the Device Log in the GUI it again mentions the broken hashtable.

Do you have an explanation for this? Is there anything else you want me to do?
