Does Jellyfin extract images from video files?

[serj1983]

Hello everyone. Does Jellyfin extract images from video files? I have a library of music videos downloaded from YouTube. I noticed that the clip art only downloaded for those clips where the file had a separate web image file and it took the image from there. For all other files, it added a single, duplicate image. These files have an embedded image, but for some reason, it doesn't take them.

Image Downloaders (Music Videos):
Embedded Image Extractor
Screen Grabber

Example of the file structure where it got the image from:
BOOM BOOM SATELLITES 『A HUNDRED SUNS』 [jlqTeCQehOs].info.json
BOOM BOOM SATELLITES 『A HUNDRED SUNS』 [jlqTeCQehOs].mp4
BOOM BOOM SATELLITES 『A HUNDRED SUNS』 [jlqTeCQehOs].webp

Where it didn't get it:
BOOM BOOM SATELLITES - Lay Your Hands on Me [5X9mrJVHbJU].info.json
