// AUTO-GENERATED DOCUMENTATION AND SERVICE
/**
* Service Description: Service that implements streaming Google Cloud Video Intelligence API.
*
* <p>This class provides the ability to make remote calls to the backing service through method
* calls that map to API methods. Sample code to get started:
*
* <pre>
* <code>
* try (StreamingVideoIntelligenceServiceClient streamingVideoIntelligenceServiceClient = StreamingVideoIntelligenceServiceClient.create()) {
* StreamingAnnotateVideoRequest request = StreamingAnnotateVideoRequest.newBuilder().build();
* ApiFuture<StreamingAnnotateVideoResponse> future = streamingVideoIntelligenceServiceClient.streamingAnnotateVideoCallable().futureCall(request);
* // Do something
* StreamingAnnotateVideoResponse response = future.get();
* }
* </code>
* </pre>
*
* <p>Note: close() needs to be called on the streamingVideoIntelligenceServiceClient object to
* clean up resources such as threads. In the example above, try-with-resources is used, which
* automatically calls close().
*
* <p>The surface of this class includes several types of Java methods for each of the API's
* methods:
*
* <ol>
* <li>A "flattened" method. With this type of method, the fields of the request type have been
* converted into function parameters. It may be the case that not all fields are available as
* parameters, and not every API method will have a flattened method entry point.
* <li>A "request object" method. This type of method only takes one parameter, a request object,
* which must be constructed before the call. Not every API method will have a request object
* method.
* <li>A "callable" method. This type of method takes no parameters and returns an immutable API
* callable object, which can be used to initiate calls to the service.
* </ol>
*
* <p>See the individual methods for example code.
*
* <p>Many parameters require resource names to be formatted in a particular way. To assist with
* these names, this class includes a format method for each type of name, and additionally a parse
* method to extract the individual identifiers contained within names that are returned.
*
* <p>This class can be customized by passing in a custom instance of
* StreamingVideoIntelligenceServiceSettings to create(). For example:
*
* <p>To customize credentials:
*
* <pre>
* <code>
* StreamingVideoIntelligenceServiceSettings streamingVideoIntelligenceServiceSettings =
* StreamingVideoIntelligenceServiceSettings.newBuilder()
* .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
* .build();
* StreamingVideoIntelligenceServiceClient streamingVideoIntelligenceServiceClient =
* StreamingVideoIntelligenceServiceClient.create(streamingVideoIntelligenceServiceSettings);
* </code>
* </pre>
*
* To customize the endpoint:
*
* <pre>
* <code>
* StreamingVideoIntelligenceServiceSettings streamingVideoIntelligenceServiceSettings =
* StreamingVideoIntelligenceServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
* StreamingVideoIntelligenceServiceClient streamingVideoIntelligenceServiceClient =
* StreamingVideoIntelligenceServiceClient.create(streamingVideoIntelligenceServiceSettings);
* </code>
* </pre>
