class UnlabeledVideoDatasetImporter(DatasetImporter): (source)
Known subclasses: fiftyone.utils.data.importers.VideoDirectoryImporter, fiftyone.utils.data.ingestors.UnlabeledVideoDatasetIngestor
Constructor: UnlabeledVideoDatasetImporter(dataset_dir, shuffle, seed, max_samples)
Interface for importing datasets of unlabeled video samples.
Typically, dataset importers should implement the parameters documented on this class, although this is not mandatory.
See :ref:`this page <writing-a-custom-dataset-importer>` for information about implementing/using dataset importers.
| Parameters | |
| dataset | the dataset directory. This may be optional for some importers |
| 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 | __next__ |
Returns information about the next sample in the dataset. |
| Property | has |
Whether this importer produces fiftyone.core.metadata.VideoMetadata instances for each video. |

| Method | __iter__ |
Undocumented |
| Method | __len__ |
The total number of samples that will be imported. |
| Method | close |
Performs any necessary actions after the last sample has been imported. |
| Method | get |
Returns the dataset info for the dataset. |
| Method | setup |
Performs any necessary setup before importing the first sample in the dataset. |
| Property | has |
Whether this importer produces a dataset info dictionary. |
| 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. |
fiftyone.utils.data.importers.VideoDirectoryImporter, fiftyone.utils.data.ingestors.UnlabeledVideoDatasetIngestorReturns information about the next sample in the dataset.

| Raises | |
StopIteration | if there are no more samples to import |
