KDE crash

[BlackBaroness]

I can't enable the video itself because my shell will freeze and crash with a black screen completely. I deleted my video file to be able to boot again. In this logs, I switched to plain color and back (but with no video selected). I use gstreamer.

Huh, I managed to collect all logs and a lot of crashes by saving command output to a file and running plasmashell from terminal. I was able to reproduce this issue with the video file I provided. After removing the video file, KDE started normally.

I disabled gstreamer and it works, but still crashes sometimes + I see strange green-screen glitches periodically (maybe when video ends)

Hi. Does this happen for any video or just the one you linked?
Did you try installing the media codecs? Or reinstalling them, that helped someone who had black video.

Can you try https://github.com/catsout/wallpaper-engine-kde-plugin/tree/qt6 with a video wallpaper to see if it is able to play correctly with it?

It seems Qt Multimedia has lots of issues with AMD GPUs #1

Unfortunately I can't make much off the crash log, I think this should be reported upstream, but not sure who it should be reported to (plasma/qt/gstreamer/amd).

I think we need a small example that can reproduce the bug, I'll make a test qml file to see if you're able to play the video outside plasmashell

I uploaded a test file here https://gist.github.com/luisbocanegra/cb758ee5f57a9e7c2838b1db349b635a

Download it, run with QSG_INFO=1 QT_LOGGING_RULES="qml.debug=true" qml6 test.qml it will play short videos from the internet in fullscreen.
In the line 15 replace the file path with yours (keeping file://). If it doesn't crash try clicking the pause/next buttons a bunch of times.

Whether it crashes or not, please share the output of that command.

Sorry, I just don't have enough time for it now. I will try to make tests you requested soon
