:param input_uri: Input video location. Currently, only Google Cloud Storage URIs are supported,
which must be specified in the following format: ``gs://bucket-id/object-id``.
:param input_content: The video data bytes.
If unset, the input video(s) should be specified via ``input_uri``.
If set, ``input_uri`` should be unset.
:param output_uri: 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``.
:param video_context: Optional, Additional video context and/or feature-specific parameters.
:param location: 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.
:param retry: Retry object used to determine when/if to retry requests.
If None is specified, requests will not be retried.
:param timeout: Optional, 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.
:param gcp_conn_id: Optional, The connection ID used to connect to Google Cloud.
Defaults to ``google_cloud_default``.
:param impersonation_chain: Optional service account to impersonate using short-term
credentials, or chained list of accounts required to get the access_token
of the last account in the list, which will be impersonated in the request.
If set as a string, the account must grant the originating account
the Service Account Token Creator IAM role.
If set as a sequence, the identities from the list must grant
Service Account Token Creator IAM role to the directly preceding identity, with first
account from the list granting this role to the originating account (templated).
