class VideoDirectoryImporter(UnlabeledVideoDatasetImporter): (source)
Constructor: VideoDirectoryImporter(dataset_dir, recursive, compute_metadata, shuffle, ...)
Importer for a directory of videos stored on disk.
See :ref:`this page <VideoDirectory-import>` for format details.
| Parameters | |
| dataset | the dataset directory |
| recursive | whether to recursively traverse subdirectories |
| compute | whether to produce
fiftyone.core.metadata.VideoMetadata instances for each
video when importing |
| shuffle | whether to randomly shuffle the order in which the samples are imported |
| seed | a random seed to use when shuffling |
| max | a maximum number of samples to import. By default, all samples are imported |
| Method | __init__ |
Undocumented |
| Method | __iter__ |
Undocumented |
| Method | __len__ |
The total number of samples that will be imported. |
| Method | __next__ |
Returns information about the next sample in the dataset. |
| Method | setup |
Performs any necessary setup before importing the first sample in the dataset. |
| Instance Variable | compute |

| Instance Variable | recursive |

| Property | has |

Inherited from DatasetImporter (via UnlabeledVideoDatasetImporter):
| Method | __enter__ |
Undocumented |
| Method | __exit__ |
Undocumented |
| Method | close |
Performs any necessary actions after the last sample has been imported. |
| Method | get |
Returns the dataset info for the dataset. |
| Method | _preprocess |
Internal utility that preprocesses the given list---which is presumed to be a list defining the samples that should be imported---by applying the values of the shuffle, seed, and max_samples parameters of the importer. |

Undocumented
Returns information about the next sample in the dataset.
| Returns | |
an(video_path, video_metadata)tuple, where |

| Raises | |
StopIteration | if there are no more samples to import |
Performs any necessary setup before importing the first sample in the dataset.
This method is called when the importer's context manager interface is
entered, DatasetImporter.__enter__.
