[Solved] Problems with animated VideoWallpapers in Plasma 5.14.4-1

Hallo friends.
I have made experiences in Sabayon and Gentoo also. Here I have installed VideoWallpapers for my Plasma 5.14.4.
On Sunday, 9th of Dec. (two days ago) I could easily install your ARCH OS with base base-devel and plasma on a laptop with core i7 and 480 GByte SSD.
This went fast despite the fact that I always have hard trouble with German settings, especially locale. This part took most of my time.
And then after installing some more packages (vivaldi, kate, mc and some more) I have a fine, fast booting ARCH OS with Plasma.

I'm using animated Video Wallpapers on my Sabayon and my Gentoo also. Now I wanted to realize Video Wallpapers for my Arch Plasma also.
As suggested in your post: https://bbs.archlinux.org/viewtopic.php?id=239407 I followed your suggestions including installation of all gstreamer and gstreamer like packages.
I also downloaded this VideoWallpaper package from store.kde.org: https://store.kde.org/p/1213488/
I installed as adviced with kpackagemanager:

kpackagetool5 -t Plasma/Wallpaper -i VideoWallpaper.tar.gz

And finally, I have an mp4 video for animate in background.

Ok, next step was to change background then. I right clicked onto my empty desktop and then Setup Desktop. Here I could choose Layout --> Video Wallpaper which now appeared to select.
But in that moment when I clicked on Video Wallpaper I received an error which is:

Error: Could not load: file://home/linuxfluesterer/.local/share/plasma/wallpapers/VideoWallpaper/contents/ui/config.qml:24
plugin cannot be loaded for module "QtMultimedia": Failed to extract plugin meta data from '/usr/lib/qt/qml/QtMultimedia/libdeclarative_multimedia.so'

I have checked for the path and the file:

//home/linuxfluesterer/.local/share/plasma/wallpapers/VideoWallpaper/contents/ui/config.qml:24

Path and file exist, so there must be something wrong with QtMultimedia

I have installed pacman -S qt5-multimedia also.

So, any idea what I could do here?

Thank you very much in advance.

Re: [Solved] Problems with animated VideoWallpapers in Plasma 5.14.4-1

It seems like it's referring to line 24 of config.qml.
Can you maybe post that file? Also do you have plugins.qmltypes at /usr/lib/qt/qml/QtMultimedia/?
These are just my guesses on how to proceed.

Oh, thank you for reply.
In between I had another problem with installing another set of packages, VirtualBox plus modules, which also brought error messages like "invalid exec format". I searched for a solution, which said, one has to upgrade any ARCH with pacman -Suy. This solved my problem with VirtualBox (the modules werde loaded now), and, surprisingly, after trying VideoWallpapers again (just an idea), I got a working animated background with the selected mp4 video file.

It seems, upgrading ARCH OS is far more important than e.g. in Sabayon. I learned something important!

But, sadly, I still have a sound problem. No sound available with ARCH OS, though with Manjaro live system I have checked with.
Thank you for joining.

Yes upgrading is important in Arch and more or less done everyday. For sound perhaps you can begin here.

Oh, thank you for the hint with alsa
I found the (I assume) solutione by another way. I assumed that not all kernel modules needed were loaded with my customized /etc/mkinitcpio.conf file.
Here I had the section MODULES extended with snd_hda_intel which seems to exclude some other needed kernel modules.
So, I simply deleted the special intel snd module and instead listed snd as module name.
I recompiled with:

mkinitcpio -p linux

and voilá, the sound was activated.

Good night to all here!
