Performs asynchronous video annotation. Progress and results can be
retrieved through the ``google.longrunning.Operations`` interface.
``Operation.metadata`` contains ``AnnotateVideoProgress`` (progress).
``Operation.response`` contains ``AnnotateVideoResponse`` (results).
Example:
>>> from google.cloud import videointelligence_v1p2beta1
>>> from google.cloud.videointelligence_v1p2beta1 import enums
>>>
>>> client = videointelligence_v1p2beta1.VideoIntelligenceServiceClient()
>>>
>>> input_uri = 'gs://demomaker/cat.mp4'
>>> features_element = enums.Feature.LABEL_DETECTION
>>> features = [features_element]
>>>
>>> response = client.annotate_video(input_uri=input_uri, features=features)
>>>
>>> def callback(operation_future):
... # Handle result.
... result = operation_future.result()
>>>
>>> response.add_done_callback(callback)
>>>
>>> # Handle metadata.
>>> metadata = response.metadata()
Args:
input_uri (str): Input video location. Currently, only `Google Cloud
Storage <https://cloud.google.com/storage/>`__ URIs are supported, which
must be specified in the following format: ``gs://bucket-id/object-id``
(other URI formats return ``google.rpc.Code.INVALID_ARGUMENT``). For
more information, see `Request
URIs <https://cloud.google.com/storage/docs/reference-uris>`__. A video
URI may include wildcards in ``object-id``, and thus identify multiple
videos. Supported wildcards: '\*' to match 0 or more characters; '?' to
match 1 character. If unset, the input video should be embedded in the
request as ``input_content``. If set, ``input_content`` should be unset.
input_content (bytes): The video data bytes. If unset, the input video(s) should be specified
via ``input_uri``. If set, ``input_uri`` should be unset.
features (list[~google.cloud.videointelligence_v1p2beta1.types.Feature]): Requested video annotation features.
video_context (Union[dict, ~google.cloud.videointelligence_v1p2beta1.types.VideoContext]): Additional video context and/or feature-specific parameters.
If a dict is provided, it must be of the same form as the protobuf
message :class:`~google.cloud.videointelligence_v1p2beta1.types.VideoContext`
output_uri (str): Optional location where the output (in JSON format) should be stored.
Currently, only `Google Cloud
Storage <https://cloud.google.com/storage/>`__ URIs are supported, which
must be specified in the following format: ``gs://bucket-id/object-id``
(other URI formats return ``google.rpc.Code.INVALID_ARGUMENT``). For
more information, see `Request
URIs <https://cloud.google.com/storage/docs/reference-uris>`__.
location_id (str): Optional cloud region where annotation should take place. Supported
cloud regions: ``us-east1``, ``us-west1``, ``europe-west1``,
``asia-east1``. If no region is specified, a region will be determined
based on video file location.
retry (Optional[google.api_core.retry.Retry]): A retry object used
to retry requests. If ``None`` is specified, requests will not
be retried.
timeout (Optional[float]): The amount of time, in seconds, to wait
for the request to complete. Note that if ``retry`` is
specified, the timeout applies to each individual attempt.
metadata (Optional[Sequence[Tuple[str, str]]]): Additional metadata
that is provided to the method.
Returns:
A :class:`~google.cloud.videointelligence_v1p2beta1.types._OperationFuture` instance.
Raises:
google.api_core.exceptions.GoogleAPICallError: If the request
failed for any reason.
google.api_core.exceptions.RetryError: If the request failed due
to a retryable error and retry attempts failed.
ValueError: If the parameters are invalid.
