Webcam availability not working for me

julianlawson commented 1 week ago

What type of installation are you running?

Server

Which Linux OS are you using?

Linux Mint 21.3 Cinnamon

Which version of LNXLink has the issue?

2024.11.0

Describe the problem

The "webcam" module seems to have stopped recognising when the camera is turned on. When I turn the webcam on, it webcam sensor stays OFF every update_interval, and the camera_used sends ON rapidly (several times a second). See MQTT messages below. I'm unclear on what the purpose of the two different sensors are; I had previously used only webcam and it seemed to work correctly.

The command to find if the camera is used is fuser /dev/video* and checks the exit code. Could you check the output of the following command when the camera is used and when it is not?

fuser /dev/video*; echo $?

Hi Vasilis, thanks for coming back to me.

The output from fuser seems to be correct, see below, though I still get OFF on topic .../monitorcontrols/webcam

Let me know if there's anything else I can do to help diagnose.

=====

@.:~$ fuser /dev/video; echo $? # before starting webcam 1 **@.:~$ fuser /dev/video; echo $? # after starting webcam /dev/video0: 3052m 0 **@.**:~$ fuser /dev/video; echo $? # after shutting down webcam

I think I misread your issue...

There are 2 different modules you are talking about.

The camera_used module is sending if the camera is used or not by any application.
The webcam module is part of 2 sensors that are created. The switch entity Webcam and the camera entity Webcam feed. When the switch is active, it starts sending the live image to the camera antity.

I hope this clears things up. Let me know if you have any issue with any of the modules I mentioned above.
