javascript - How to skip the beginning and end of a video in online video playback? ?

Example: iQIYI’s skip opening and ending:

How did you get the time period here? ? Do you think it was added or was it determined automatically by the system? ?

Personally, I feel that automatic judgment cannot be so accurate. Is it set when adding videos in the background? ?
