data_juicer.ops.mapper.video_resize_resolution_mapper module¶
- class data_juicer.ops.mapper.video_resize_resolution_mapper.VideoResizeResolutionMapper(min_width: int = 1, max_width: int = 9223372036854775807, min_height: int = 1, max_height: int = 9223372036854775807, force_original_aspect_ratio: str = 'disable', force_divisible_by: Annotated[int, Gt(gt=0)] = 2, save_dir: str = None, *args, **kwargs)[source]¶
Bases:
MapperResizes video resolution based on specified width and height constraints.
This operator resizes videos to fit within the provided minimum and maximum width and height limits. It can optionally maintain the original aspect ratio by adjusting the dimensions accordingly. The resized videos are saved in the specified directory or the same directory as the input if no save directory is provided. The key metric for resizing is the video’s width and height, which are adjusted to meet the constraints while maintaining the aspect ratio if configured. The force_divisible_by parameter ensures that the output dimensions are divisible by a specified integer, which must be a positive even number when used with aspect ratio adjustments.

Initialization method.
- Parameters:
min_width – Videos with width less than ‘min_width’ will be mapped to videos with equal or bigger width.
max_width – Videos with width more than ‘max_width’ will be mapped to videos with equal of smaller width.
min_height – Videos with height less than ‘min_height’ will be mapped to videos with equal or bigger height.
max_height – Videos with height more than ‘max_height’ will be mapped to videos with equal or smaller height.
force_original_aspect_ratio – Enable decreasing or increasing output video width or height if necessary to keep the original aspect ratio, including [‘disable’, ‘decrease’, ‘increase’].
force_divisible_by – Ensures that both the output dimensions, width and height, are divisible by the given integer when used together with force_original_aspect_ratio, must be a positive even number.
save_dir – The directory where generated video files will be stored. If not specified, outputs will be saved in the same directory as their corresponding input files. This path can alternatively be defined by setting the DJ_PRODUCED_DATA_DIR environment variable.
