Description Ken Arromdee 2021-06-22 02:48:55 CEST

Description of problem:


Version-Release number of selected component (if applicable):


How reproducible:
Always


Steps to Reproduce:
1. Run webcamoid
2. Observe error.

QQmlApplicationEngine failed to load component
qrc:/Webcamoid/share/qml/main.qml:23:1: module "QtQuick.Layouts" is not installed
qrc:/Webcamoid/share/qml/main.qml:21:1: module "QtQuick.Window" is not installed
qrc:/Webcamoid/share/qml/main.qml:23:1: module "QtQuick.Layouts" is not installed
qrc:/Webcamoid/share/qml/main.qml:21:1: module "QtQuick.Window" is not installed

Researching this shows me that QtQuick.Layouts and Window should be in /usr/lib64/qt5/qml/QtQuick/Layouts and Window.  It's not in there.  Furthermore, doing a search for installable software named QtQuick shows qtquickcontrols5 which contains Dialogs, Extras, etc. but not Layouts, and nothing else contains Layouts.

Comment 1 Dave Hodgins 2021-06-22 03:47:30 CEST

From urpmf QtQuick.Layouts ...
qtdeclarative5:/usr/lib64/qt5/qml/QtQuick/Layouts/libqquicklayoutsplugin.so

Please install qtdeclarative5. If that fixes the issue it's just a missing
requires.

Comment 2 Lewis Smith 2021-06-22 09:51:33 CEST

Thank you Ken for the report.

Just to note also that pkg 'qtdeclarative5' also has Window things:
 $ urpmf QtQuick.Window | grep -v qtcreator
 qtdeclarative5:/usr/lib64/qt5/qml/QtQuick/Window.2
 qtdeclarative5:/usr/lib64/qt5/qml/QtQuick/Window.2/libwindowplugin.so
 qtdeclarative5:/usr/lib64/qt5/qml/QtQuick/Window.2/plugins.qmltypes
 qtdeclarative5:/usr/lib64/qt5/qml/QtQuick/Window.2/qmldir
nothing without the .2 suffix.

Comment 3 Ken Arromdee 2021-06-22 16:22:46 CEST

Okay, installing that now lets webcamoid work.

webcamoid shows me nothing for virtual camera driver and apparently it can use akvcam or v4l2loopback, neither of which come with Mageia.  I don't know if that still counts as a bug.  But it's irrelevant since I was hoping this could let me create a virtual camera with a virtual background, and it doesn't.

Comment 4 Dave Hodgins 2021-06-22 21:20:14 CEST

Thanks for confirming that's the fix that needed.

Assigning to all packagers as webcamoid does not have a registered maintainer.

Comment 7 Thomas Andrews 2022-09-22 14:14:40 CEST

@Brian: It looks like qtdeclarative5 was probably already installed on your system when you installed the updates. I believe we need a test on a system where qtdeclarative 5 is not already installed, to be sure this update pulls it in.

no worries - removing the ok

Comment 9 Herman Viaene 2022-09-26 10:52:10 CEST

The qt package mentioned above is already installed here. Trying to remove it would take following with it:
- dropbox-servicemenu-0.16.1-7.mga8.noarch
- kdenlive-20.12.0-4.mga8.x86_64
- konq-plugins-20.12.0-1.mga8.x86_64
- konqueror-20.12.0-1.mga8.x86_64
- mageiawelcome-2.16-1.mga8.noarch
- plasma-workspace-5.20.4-5.2.mga8.x86_64
- sddm-0.19.0-15.1.mga8.x86_64
- task-plasma5-minimal-5.20.4-2.mga8.noarch
To me this would imply, the test as asked by Thomas is only possible on a system which has Plasma not installed at all ?????

Comment 10 Mauricio Andrés Bustamante Viveros 2022-09-26 19:33:47 CEST

OK

I am not plasma/gnome user so qtdeclarative must be selected with webcamoid
Using my VM

Trying to remove qtdeclarative5 that is installed in MATE/LXDE Desktop Enviroments:

Is required to remove the following packages:

- mageiawelcome-2.16-1.mga8.noarch
So I removed it and restarted

Comment 11 Thomas Andrews 2022-10-01 02:21:07 CEST

Just to confirm, I tried this is a Gnome guest in VirtualBox. The qtdeclarative5 package was already installed, but was only required by mageiawelcome. Removed them, then installed webcamoid, which only required lib64avkys8. Then I used qarepo to get the update packages. Installing the updates now drew in qtdeclarative5 once more.

I do not own a webcam, so was unable to go farther.

OKing, and validating.
