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.

Parameters:

• 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.

• keep_original_sample – whether to keep the original sample. If it’s set to False, there will be only cut sample in the final datasets and the original sample will be removed. It’s True in default.

• args – extra args

• kwargs – extra args
