Hardware video acceleration makes it possible for the video card to decode/encode video, thus offloading the CPU and saving power.

First, verify acceleration you can install and run nvtop, it will show a decoding usage when Hardware acceleration is working:

If nvtop is not available you can use:

If there is no decoding usage you will have to enable video acceleration in your system

To recover from crash remove the videos from the configuration using this command below in terminal/tty

sed -i 's/^VideoUrls=.*$/VideoUrls=/g' $HOME/.config/plasma-org.kde.plasma.desktop-appletsrc $HOME/.config/kscreenlockerrc

then reboot or restart plasmashell systemctl --user restart plasma-plasmashell.service or plasmashell --replace if the former doesn't work.

Install the media codecs and qt6-multimedia and gstreamer packages if you don't have them:

openSUSE
```
sudo zypper install opi
opi codecs
sudo zypper install qt6-multimedia gstreamer-plugins-libav
```
Arch
```
sudo pacman -S qt6-multimedia qt6-multimedia-gstreamer gst-libav --needed
```
If you need extra codecs see https://wiki.archlinux.org/title/GStreamer

PRs to expand this list are welcome :)
Reboot
If after that the video doesn't play, fails to loop or crashes your Desktop (remove the plugin configuration using sed command above if needed), try switching the Qt Media backend to gstreamer (default is ffmpeg):

Create the file ~/.config/plasma-workspace/env/qt-media-backend.sh
```
#!/bin/bash
export QT_MEDIA_BACKEND=gstreamer
```
Reboot again to apply the changes, and verify it was correctly set by running echo $QT_MEDIA_BACKEND

Video still doesn't play/keeps crashing? Follow these steps

Run journalctl -f > journal.txt and sudo dmesg -wHT > dmesg.txt in separate terminals
While both commands are running switch from the Image wallpaper plugin to video wallpaper and reproduce the issue
Then stop both commands
If needed, remove the plugin configuration (sed command above)
Get your system information from kinfo > sysinfo.txt command or from System settings > About this System
Save the file from here as test.qml. Run the test qml with from terminal QT_FFMPEG_DEBUG=1 QSG_INFO=1 QT_LOGGING_RULES="*.debug=true" qml6 test.qml 2> qml_video_test_log.txt , (qml6 may be qml-qt6 or /usr/lib/qt6/bin/qml please confirm is qt6 one with --version) this file will play some public test videos from internet in fullscreen. If it doesn't crash immediately, try clicking the pause/next buttons a bunch of times.
Run lspci -k | grep -EA3 'VGA|3D|Display' > lspci.txt
Create a new new issue describing the problem and how to reproduce, and attach those files including wether running the test.qml also crashes or not.
