When the Astronomy Picture of the Day (APOD) is a video, the KDE wallpaper (via Configure -> Desktop Settings -> Wallpaper Type: "Picture of the Day", Provider: "Astronomy (NASA)") comes out as a solid black background. Example, from today, 2020-08-05 (August 5, 2020): https://apod.nasa.gov/apod/ap200805.html shows a YouTube video (source: https://www.youtube.com/watch?v=X_UOLpUDwpU). Because of this, my desktop background is blank (solid black). It would be nice to either (a) continue using a previous day's APOD picture, or better yet, (b) use a snapshot of the YouTube video. This appears to be possible by fetching from a well-defined URL: https://img.youtube.com/vi/<VIDEO ID>/maxresdefault.jpg (In the example above, it would be https://img.youtube.com/vi/X_UOLpUDwpU/maxresdefault.jpg)
