Hi everyone! First of all, sorry for my english, it is not my native language.
I hope that this will help anyone who wants to use a custom wallpaper, but doesn't want to replace video every time manually.
If this helped, you can star the GitHub repo so I can know that I helped someone.
If there is any issue, feel free to open it on GitHub
