Reference documentation and code samples for the Google Cloud Video Intelligence v1 API class AnnotateVideoRequest.
Input video location. Currently, only
Cloud 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. 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.
Optional. Cloud region where annotation should take place. Supported cloud
regions are: us-east1, us-west1, europe-west1, asia-east1. If no
region is specified, the region will be determined based on video file
location.
Optional. Location where the output (in JSON format) should be stored.
Currently, only Cloud Storage
URIs are supported. These 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.
