[Bug]: AV1 Video's Crash's plasmashell

[TheReiko69]

I have:

• Searched if this issue hasn't been reported yet.
• Verified that I am using the latest version (Wallpaper settings > top right corner for version 1.0.0 and later), should be the same as https://github.com/luisbocanegra/plasma-smart-video-wallpaper-reborn/releases/latest

Install method used:

• Using Plasma's "Add new widget" (KDE Store)
• AUR
• Manually from the latest source code

Describe the bug
The video hard crash's my plasmashell instance by having a memory leak when this video so much as even touch's the video file menu for this plugin. while also just displaying a black screen where the video should be playing. taking it out resolves the issue completely.

Steps to reproduce

1. Added a video to the video menu.
2. enabled it
3. applied the changes
4. You now have a ticking time bomb black screen.

Observed Result
Video plays, observed Ram usage in Mission Center, it slowly goes up and up until I disable and completely remove the video from the plugin, if left unchecked it will hard crash my system through plasmashell

Expected Result
The video to play and not eat all my ram to eventually lead to a crash

Screenshots/Video
Video in question is unable to be uploaded to github.

I have also put another video I downloaded into the wallpaper and it was a vp9 video. This video I used that caused the massive memory leak is an av1 video. which is my biggest suspect for the culprit of this issue. and if it is the culprit then my next question is will av1 ever be supported or how could I possibly make it so av1 is a usable codec for my video wallpaper without it crashing my system. I would really perfer to not reencode the video to make sure it retains as much quality as possible.

Upon further inspection and a lil testing I have come to conclude that the av1 codec libdav1d that youtube uses doesn't work with the video wallpaper. as with the video that was crashing before I had downloaded the vp9 version of it off youtube and now it works perfectly flawlessly with no issue's. any sort of fix to make av1 video's work would be nice as I do like av1 video's quite a bit and would prefer to use it over other codecs.
