Methods

AnnotateVideo(AnnotateVideoRequest, CallSettings)

public virtual Operation<AnnotateVideoResponse, AnnotateVideoProgress> AnnotateVideo(AnnotateVideoRequest request, CallSettings callSettings = null)

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).

Parameters
Name Description
request AnnotateVideoRequest

The request object containing all of the parameters for the API call.
callSettings CallSettings

If not null, applies overrides to this RPC call.
Returns
Type Description
OperationAnnotateVideoResponseAnnotateVideoProgress

The RPC response.
Example 
// Create client
VideoIntelligenceServiceClient videoIntelligenceServiceClient = VideoIntelligenceServiceClient.Create();
// Initialize request argument(s)
AnnotateVideoRequest request = new AnnotateVideoRequest
{
    InputUri = "",
    Features =
    {
        Feature.Unspecified,
    },
    VideoContext = new VideoContext(),
    OutputUri = "",
    LocationId = "",
    InputContent = ByteString.Empty,
};
// Make the request
Operation<AnnotateVideoResponse, AnnotateVideoProgress> response = videoIntelligenceServiceClient.AnnotateVideo(request);

// Poll until the returned long-running operation is complete
Operation<AnnotateVideoResponse, AnnotateVideoProgress> completedResponse = response.PollUntilCompleted();
// Retrieve the operation result
AnnotateVideoResponse result = completedResponse.Result;

// Or get the name of the operation
string operationName = response.Name;
// This name can be stored, then the long-running operation retrieved later by name
Operation<AnnotateVideoResponse, AnnotateVideoProgress> retrievedResponse = videoIntelligenceServiceClient.PollOnceAnnotateVideo(operationName);
// Check if the retrieved long-running operation has completed
if (retrievedResponse.IsCompleted)

}

AnnotateVideo(string, IEnumerable<Feature>, CallSettings)

public virtual Operation<AnnotateVideoResponse, AnnotateVideoProgress> AnnotateVideo(string inputUri, IEnumerable<Feature> features, CallSettings callSettings = null)

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).

Parameters
Name Description

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.
features IEnumerableFeature

Required. Requested video annotation features.
