Claim 7:
8. The video sound-picture matching method according to claim 1, wherein the moving direction of the start-stop mark is a reverse direction, and the initial position of the start-stop mark is greater than or equal to a start frame of a pth active segment, the p being an integer greater than or equal to 1 and less than or equal to N, and determining the active segment comprises:
determining a minimum value of a first reverse duration according to a minimum scaling, the initial position of the start-stop mark, and the start frame of the pth active segment;
determining a maximum value of the first reverse duration according to a maximum scaling, the initial position of the start-stop mark, and an end frame of a (p−1)th active segment;
determining a target reverse duration interval according to the minimum value of the first reverse duration and the maximum value of the first reverse duration;
determining, in response to determining that the voice segment is within the target reverse duration interval, the active segment according to at least one of the pth active segment and the (p−1)th active segment;
the method further comprises:
updating the initial position of the start-stop mark in response to determining that a condition for updating the position of the start-stop mark is met; and
adjusting the moving direction of the start-stop mark to be a forward direction in response to determining that the updated initial position of the start-stop mark is less than or equal to a position corresponding to a start frame of the first active segment.
