- augly.video.helpers.intensity.time_crop_or_pad_intensity_helper(metadata)
Computes intensity of a transform that consists of temporal cropping or padding. For these types of transforms the intensity is defined as the percentage of video time that has been cut out (for cropping) or added (for padding). When computing the percentage, the denominator should be the longer of the src & dst durations so the resulting percentage isn’t greater than 100.

- augly.video.helpers.compute_changed_segments(name, src_segments, dst_segments, src_duration, dst_duration, speed_factor, **kwargs)
This function performs the logic of computing the new matching segments based on the old ones, for the set of transforms that temporally change the video.
Returns the lists of new src segments & dst segments, respectively.
- augly.video.helpers.compute_segments(name, src_duration, dst_duration, metadata, **kwargs)
Compute matching pairs of src_segment -> dst_segment, given the kwargs of the transform, as well as the metadata about previously applied transforms.
- augly.video.helpers.compute_time_crop_segments(src_segment, dst_segment, speed_factor, crop_start, crop_end, new_src_segments, new_dst_segments)
Calculates how the given matching pair src_segment & dst_segment change given a temporal crop starting at crop_start & ending at crop_end. We can use the same logic here for multiple transforms, by setting the crop_start & crop_end depending on the transform kwargs.
Doesn’t return anything, but appends the new matching segments in the dst video corresponding to the pair passed in to new_src_segments & new_dst_segments, if the segment pair still matches in the dst video. If the passed in segment pair is cropped out as a result of this temporal crop, nothing will be appended to the lists, since the segment pair doesn’t exist in the dst video.
