Unity obtains a frame of the video, generates a thumbnail image

Unity does not have an API to directly capture a frame image of a video, so it's up to you to write a thumbnail.

Pictures and videos can be used in this way to generate thumbnails, the other, reproduced please indicate the source, thank you.
