Claim 9:
10. The video sound-picture matching method according to claim 8, wherein
determining the active segment comprises:
determining a maximum value of the second reverse duration according to the initial position of the start-stop mark and an end frame of the (p−1)th active segment, wherein the maximum value of the second reverse duration is less than the maximum value of the first reverse duration;
determining a second reverse duration interval according to the maximum value of the first reverse duration and the maximum value of the second reverse duration; and
scaling, in response to determining that the voice segment is within the second reverse duration interval, a duration between the end frame of the (p−1)th active segment and the initial position of the start-stop mark according to a duration of the voice segment to obtain the active segment; and

updating the initial position of the start-stop mark comprises:
meeting the condition for updating the position of the start-stop mark in response to determining that the voice segment is within the second reverse duration interval; and
updating the initial position of the start-stop mark to a position corresponding to the end frame of the (p−1)th active segment.
