A[now] indicates the current viewing position of the user, and A[temp] indicates the temporary position during the movement.
实施例三Embodiment 3
进一步的实施例中，如图3所示，本实施例三与实施例一的流程步骤基本相同，不同的是，实施例一的步骤300替换为实施例三的步骤301和步骤302，在实际应用例中，将进度条数组记为A[N]，音视频文件的起始位置对应的采样点记为A[0]，音视频文件的结束位置对应的采样点记为A[i]，当前播放位置对应的采样点记为A[now]，其中，步骤301和步骤302具体为：In a further embodiment, as shown in FIG. 3, the process steps of the third embodiment are substantially the same as those of the first embodiment. The difference is that the step 300 of the first embodiment is replaced by the step 301 and the step 302 of the third embodiment. In the application example, the progress bar array is recorded as A[N], the sampling point corresponding to the start position of the audio and video file is recorded as A[0], and the sampling point corresponding to the end position of the audio and video file is recorded as A[i], The sampling point corresponding to the current playback position is recorded as A[now], where steps 301 and 302 are specifically:

具体实施时，A[temp1]代表当前播放位置A[now]与结束位置A[i]的中间位置的采样点。假设第一步用户的操作是快进，那么就将采样点A[temp1] 定位到采样点A[now]与采样点A[i]中间的采样点所对应的位置，第二步如果用户继续快进的话就将采样点A[temp1]重新定位到当前采样点A[temp1]与采样点A[i]的中间的采样点所对应的位置，如果第二步用户是后退的话就将采样点A[temp1]重新定位到采样点A[0]与当前采样点A[temp1]中间的采样点所对应的位置。In specific implementation, A[temp1] represents a sampling point of an intermediate position between the current playback position A[now] and the end position A[i]. Assuming the first step of the user's operation is fast forward, then the sampling point A[temp1] Position the position corresponding to the sampling point between the sampling point A[now] and the sampling point A[i]. In the second step, if the user continues to fast forward, reposition the sampling point A[temp1] to the current sampling point A[temp1 ] The position corresponding to the sampling point in the middle of the sampling point A[i], if the second step user is backward, the sampling point A[temp1] is relocated to the sampling point A[0] and the current sampling point A[temp1] The position corresponding to the sampling point in the middle.
实施例四Embodiment 4
进一步的实施例中，如图4所示，本实施例四与实施例一的流程步骤基本相同，不同的是，实施例一的步骤400替换为实施例四的步骤401和步骤402，在实际应用例中，将进度条数组记为A[N]，音视频文件的起始位置对应的采样点记为A[0]，音视频文件的结束位置对应的采样点记为A[i]，当前播放位置对应的采样点记为A[now]，其中，步骤401和步骤402具体为：In a further embodiment, as shown in FIG. 4, the flow of the fourth embodiment is substantially the same as that of the first embodiment. The difference is that the step 400 of the first embodiment is replaced by the step 401 and the step 402 of the fourth embodiment. In the application example, the progress bar array is recorded as A[N], the sampling point corresponding to the start position of the audio and video file is recorded as A[0], and the sampling point corresponding to the end position of the audio and video file is recorded as A[i], The sampling point corresponding to the current playing position is recorded as A[now], wherein step 401 and step 402 are specifically:
步骤401、若所述用户操作为快退操作，则将采样点A[temp2]定位到采样点A[0]和采样点A[now]中间的采样点所对应的位置。Step 401: If the user operation is a fast rewind operation, the sampling point A[temp2] is located to a position corresponding to the sampling point between the sampling point A[0] and the sampling point A[now].
步骤402、判断用户再次执行的操作，若用户再次执行快退操作，则将采样点A[temp2]重新定位到采样点A[0]和当前采样点A[temp2]中间的采样点所对应的位置，若用户再次执行快进操作，则将采样点A[temp2]重新定位到当前采样点A[temp2]和采样点A[i]中间的采样点所对应的位置。Step 402: Determine an operation performed by the user again. If the user performs the fast rewind operation again, relocate the sampling point A[temp2] to the sampling point between the sampling point A[0] and the current sampling point A[temp2]. Position, if the user performs the fast forward operation again, the sampling point A[temp2] is repositioned to the position corresponding to the sampling point between the current sampling point A[temp2] and the sampling point A[i].
具体实施时，A[temp2]表示起始位置A[0]与当前播放位置A[now]的中间位置的采样点。假设第一步用户是后退的话就将采样点A[temp2]定位到采样点A[0]与采样点A[now]中间的采样点所对应的位置，第二步如果用户的操作是继续后退则将采样点A[temp2]重新定位到采样点A[0]与当前采样点A[temp2]中间的采样点所对应的位置。如果第二步用户的操作是快进则将采样点A[temp2]重新定位到当前采样点A[temp2]与采样点A[i]中间的采样点所对应的位置。In specific implementation, A[temp2] represents a sampling point of the intermediate position between the starting position A[0] and the current playing position A[now]. Assuming that the first user is backing up, the sampling point A[temp2] is positioned to the position corresponding to the sampling point between the sampling point A[0] and the sampling point A[now], and the second step is to continue the user's operation. Then, the sampling point A[temp2] is repositioned to the position corresponding to the sampling point between the sampling point A[0] and the current sampling point A[temp2]. If the second step of the user's operation is fast forward, the sampling point A[temp2] is repositioned to the position corresponding to the sampling point between the current sampling point A[temp2] and the sampling point A[i].

步骤10、预先设置一个取消键用于取消本轮定位。Step 10. Set a cancel button in advance to cancel the current round of positioning.
具体实施时，保留一个操作是用户取消本轮二分查找的操作。比如用户正在使用以上的方法进行快进快退操作，最开始的本意是后退，即是想定位到A[0]与A[now]之间的某个位置，但是突然改变主意想定位到A[now]与A[N]之间的某个位置，只需要按下取消当前二分查找的策略即可开始新一轮的二分查找的流程。按照以上的步骤类推，既能快速又能准确定位到用户的理想移动位置。In the specific implementation, retaining an operation is an operation in which the user cancels the round binary search. For example, the user is using the above method to fast forward and rewind. The original intention is to retreat, that is, to locate a position between A[0] and A[now], but suddenly change the mind to locate A. A certain position between [now] and A[N], you only need to press the strategy to cancel the current binary search to start a new round of binary search process. According to the above steps, it can quickly and accurately locate the user's ideal moving position.
