[Software] Webcamoid fails to run

[James1234]

Webcamoid won't run, giving the following error message on the CLI:

[2025-08-27 07:54:18.565, Webcamoid, 0x728812837c80, (0)]...
warning: QQmlApplicationEngine failed to load component

How do I fix this?

I can confirm. My HP Pavilion G7-1070us laptops webcam is identified by lsusb as a Chicony Electronics Co., Ltd HP Integrated Webcam. After installing Webcamoid, when launched, it failed. In my case, this is the pertinent output when webcamoid is launched from the CLI:

​

The application execution halts after displaying the last line above. It says that the module "Qt.labs.settings" is not installed, but that isn't true.

A Google search on Webcamoid warning: qrc:/Webcamoid/share/qml/VideoOutputs.qml:24:1: module "Qt.labs.settings" is not installed finds this:

Debian Bug report logs #1089101 webcamoid: Webcamoid fails to run (https://bugs-devel.debian.org/cgi-bi...gi?bug=1089101)

The 'fix' is to install package qml6-module-qt-labs-settings (sudo apt install qml6-module-qt-labs-settings)

I did this then launched the app. It works.

I've reported this 'bug'. See https://github.com/webcamoid/webcamoid/issues/761
