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
`Operation<AnnotateVideoResponse, AnnotateVideoProgress>`	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)
{
    // If it has completed, then access the result
    AnnotateVideoResponse retrievedResult = retrievedResponse.Result;
}

AnnotateVideo(String, IEnumerable<Feature>, CallSettings)

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

Parameters
Name	Description
`inputUri`	`String` 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`	`IEnumerable<Feature>` Required. Requested video annotation features.
`callSettings`	`CallSettings` If not null, applies overrides to this RPC call.

Returns
Type	Description

    "gs://cloud-samples-data/video/gbikes_dinosaur.mp4",
    new[] { Feature.LabelDetection });
Operation<AnnotateVideoResponse, AnnotateVideoProgress> resultOperation = operation.PollUntilCompleted();

VideoAnnotationResults result = resultOperation.Result.AnnotationResults[0];
