Mapper to split video by duration.

__init__(split_duration: float = 10, min_last_split_duration: float = 0, keep_original_sample: bool = True, *args, **kwargs)

Initialization method.

参数:

• split_duration -- duration of each video split in seconds.

• min_last_split_duration -- The minimum allowable duration in seconds for the last video split. If the duration of the last split is less than this value, it will be discarded.
