Hello,

Debian unstable
webcamoind version: 9.2.3-1

I see similar problem (missing component):

[2024-12-06 11:10:23.195, Webcamoid, 0x7fb3799d5c80,  (0)] warning: QQmlApplicationEngine failed to load component

apt install qml6-module-qt-labs-settings

fixed the problem. So probably the updating of dependencies is needed.

Many thanks.

Best regards.

Thanks Milan!  Installing qml6-module-qt-labs-settings didn't resolve
the reported error, though, but helped me get webcamoid running nonetheless.

To resolve `module "QtQuick.Controls" plugin "qtquickcontrols2plugin"
not found` warning, qml6-module-qtquick-controls needs to be installed.
But wait!  There's more!

Next warning: module "QtQuick.Layouts" is not installed
Resolution: install qml6-module-qtquick-layouts

Next warnings: Now we get `module "Qt.labs.settings" is not installed`
as well as `module "QtCore" is not installed` which is resolved by
installing qml6-module-qt-labs-settings plus qml6-module-qtcore.  We're
not done yet, though!

Next warning: module "Qt.labs.platform" is not installed
Resolution: install qml6-module-qt-labs-platform

Now, webcamoid starts, but even more dependencies may be required which
I already had installed.  Fortunately, the missing module names reported
mapped to a package name consistently.  Try apt install
qml6-module-<TAB><TAB> to see all available.

Dear Maintainer,

Running webcamoid from a GUI menu silently fails.

Running webcamoid from a terminal indicates failure to find a qml
module

This can be fixed by manually installing debian package:

  qml6-module-qt-labs-settings

So it seems that the debian package has omitted that dependency.

Dear Sirs,

Under Debian Sid, I cannot install webcamoid:

duane@DuanesSpectre16:~$ sudo apt install webcamoid

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
