Client for Cloud Video Intelligence API

class google.cloud.videointelligence_v1p2beta1.VideoIntelligenceServiceClient(transport=None, channel=None, credentials=None, client_config=None, client_info=None)[source]

Service that implements Google Cloud Video Intelligence API.

Constructor.

Parameters

  • (Union[VideoIntelligenceServiceGrpcTransport, (transport) – Callable[[~.Credentials, type], ~.VideoIntelligenceServiceGrpcTransport]): A transport instance, responsible for actually making the API calls. The default transport uses the gRPC protocol. This argument may also be a callable which returns a transport instance. Callables will be sent the credentials as the first argument and the default transport class as the second argument.

  • channel (grpc.Channel) – DEPRECATED. A Channel instance through which to make calls. This argument is mutually exclusive with credentials; providing both will raise an exception.

  • credentials (google.auth.credentials.Credentials) – The authorization credentials to attach to requests. These credentials identify this application to the service. If none are specified, the client will attempt to ascertain the credentials from the environment. This argument is mutually exclusive with providing a transport instance to transport; doing so will raise an exception.

  • client_config (dict) – DEPRECATED. A dictionary of call options for each method. If not specified, the default configuration is used.

  • client_info (google.api_core.gapic_v1.client_info.ClientInfo) – The client info used to send a user-agent string along with API requests. If None, then default info will be used. Generally, you only need to set this if you’re developing your own client library.

annotate_video(input_uri=None, input_content=None, features=None, video_context=None, output_uri=None, location_id=None, retry=<object object>, timeout=<object object>, metadata=None)[source]

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://cloud-samples-data/video/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()
Parameters

  • input_uri (str) – Input video location. Currently, only Google Cloud 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. 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[Feature]) – Requested video annotation features.

  • video_context (Union[dict, 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 VideoContext

  • output_uri (str) – Optional location where the output (in JSON format) should be stored. Currently, only Google Cloud 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.

  • 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 _OperationFuture instance.
