fiftyone.utils.data.ingestors.UnlabeledVideoDatasetIngestor

class documentation

class UnlabeledVideoDatasetIngestor(UnlabeledVideoDatasetImporter, VideoIngestor): (source)

Constructor: UnlabeledVideoDatasetIngestor(dataset_dir, samples, sample_parser, max_samples)

Dataset importer that ingests unlabeled videos into the provided dataset_dir during import.

The source videos are parsed from the provided samples using the provided fiftyone.utils.data.parsers.UnlabeledVideoSampleParser.

The source videos are directly copied from their source locations into dataset_dir, maintaining the original filenames, unless a name conflict would occur, in which case an index of the form "-%d" % count is appended to the base filename.

Parameters
dataset_dir	the directory where input videos will be ingested into
samples	an iterable of samples that can be parsed by `sample_parser`
sample_parser	an `fiftyone.utils.data.parsers.UnlabeledVideoSampleParser` to use to parse the samples
max_samples	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	`sample_parser`	Undocumented
Instance Variable	`samples`	Undocumented
Property	`has_dataset_info`	Whether this importer produces a dataset info dictionary.
Property	`has_video_metadata`	Whether this importer produces `fiftyone.core.metadata.VideoMetadata` instances for each video.
Instance Variable	`_iter_samples`	Undocumented
Instance Variable	`_num_imported`	Undocumented
Instance Variable	`_num_samples`	Undocumented

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_dataset_info`	Returns the dataset info for the dataset.
Method	`_preprocess_list`	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.

Inherited from VideoIngestor (via UnlabeledVideoDatasetImporter, DatasetImporter):

Undocumented

def __iter__(self): (source) ¶

Undocumented

def __len__(self): (source) ¶

overrides fiftyone.utils.data.importers.DatasetImporter.__len__

The total number of samples that will be imported.

Raises
`TypeError`	if the total number is not known

def __next__(self): (source) ¶

overrides fiftyone.utils.data.importers.UnlabeledVideoDatasetImporter.__next__

Returns information about the next sample in the dataset.

Returns
an`(video_path, video_metadata)` tuple , `where`	`video_path`: the path to the video on disk `video_metadata`: an `fiftyone.core.metadata.VideoMetadata` instances for the video, or `None` if `has_video_metadata` is `False`
Raises
`StopIteration`	if there are no more samples to import
