class  pixeltable.iterators.VideoSplitter

Iterator over segments of a video file, which is split into fixed-size segments of length segment_duration seconds. Args: duration: Video segment duration in seconds overlap: Overlap between consecutive segments in seconds. Only available for mode='fast'. min_segment_duration: Drop the last segment if it is smaller than min_segment_duration. mode: Segmentation mode:
  • 'fast': Quick segmentation using stream copy (splits only at keyframes, approximate durations)
  • 'accurate': Precise segmentation with re-encoding (exact durations, slower) video_encoder: Video encoder to use. If not specified, uses the default encoder for the current platform. Only available for mode='accurate'. video_encoder_args: Additional arguments to pass to the video encoder. Only available for mode='accurate'.

​
method  accurate_iter()

accurate_iter() -> Iterator[dict[str, Any]]

​
method  close()

close() -> None
Close the iterator and release all resources

​
method  create()

create(**kwargs: Any) -> tuple[type[ComponentIterator], dict[str, Any]]

​
method  fast_iter()

fast_iter() -> Iterator[dict[str, Any]]

​
method  input_schema()

input_schema() -> dict[str, pixeltable.type_system.ColumnType]
Provide the Pixeltable types of the init() parameters The keys need to match the names of the init() parameters. This is equivalent to the parameters_types parameter of the @function decorator.

​
method  output_schema()

output_schema(
    *args: Any,
    **kwargs: Any
) -> tuple[dict[str, pixeltable.type_system.ColumnType], list[str]]
Specify the dictionary returned by next() and a list of unstored column names Returns:
  • tuple[dict[str, pixeltable.type_system.ColumnType], list[str]]: a dictionary which is turned into a list of columns in the output table a list of unstored column names

​
method  set_pos()

set_pos(pos: int) -> None
Set the iterator position to pos
