Args:
request (:class:`google.cloud.videointelligence_v1.types.AnnotateVideoRequest`):
The request object. Video annotation request.
input_uri (:class:`str`):
Input video location. Currently, only `Cloud
Storage <https://cloud.google.com/storage/>`__ URIs are
supported. URIs must be specified in the following
format: ``gs://bucket-id/object-id`` (other URI formats
return
[google.rpc.Code.INVALID_ARGUMENT][google.rpc.Code.INVALID_ARGUMENT]).
For more information, see `Request
URIs <https://cloud.google.com/storage/docs/request-endpoints>`__.
To identify multiple videos, a video URI may include
wildcards in the ``object-id``. 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``
must be unset.
This corresponds to the ``input_uri`` field
on the ``request`` instance; if ``request`` is provided, this
should not be set.
features (:class:`Sequence[google.cloud.videointelligence_v1.types.Feature]`):
Required. Requested video annotation
features.
This corresponds to the ``features`` field
on the ``request`` instance; if ``request`` is provided, this
should not be set.
retry (google.api_core.retry.Retry): Designation of what errors, if any,
should be retried.
timeout (float): The timeout for this request.
metadata (Sequence[Tuple[str, str]]): Strings which should be
sent along with the request as metadata.
Returns:
google.api_core.operation_async.AsyncOperation:
An object representing a long-running operation.
The result type for the operation will be :class:`google.cloud.videointelligence_v1.types.AnnotateVideoResponse` Video annotation response. Included in the response
field of the Operation returned by the GetOperation
call of the google::longrunning::Operations service.
