Quickstart

Before you begin

1. Select or create a Cloud Platform project.
2. Enable billing for your project.
3. Enable the Google Cloud Video Intelligence API.
4. Set up authentication with a service account so you can access theAPI from your local workstation.

Installing the client library

npm install @google-cloud/video-intelligence

Using the client library

// Imports the Google Cloud Video Intelligence libraryconst videoIntelligence = require('@google-cloud/video-intelligence');// Creates a clientconst client = new videoIntelligence.VideoIntelligenceServiceClient();// The GCS uri of the video to analyzeconst gcsUri = 'gs://cloud-samples-data/video/cat.mp4';// Construct requestconst request = {  inputUri: gcsUri,  features: ['LABEL_DETECTION'],};// Execute requestconst [operation] = await client.annotateVideo(request);console.log(  'Waiting for operation to complete... (this may take a few minutes)');const [operationResult] = await operation.promise();// Gets annotations for videoconst annotations = operationResult.annotationResults[0];// Gets labels for video from its annotationsconst labels = annotations.segmentLabelAnnotations;labels.forEach(label => {  console.log(`Label ${label.entity.description} occurs at:`);  label.segments.forEach(segment => {    segment = segment.segment;    if (segment.startTimeOffset.seconds === undefined) {      segment.startTimeOffset.seconds = 0;    }    if (segment.startTimeOffset.nanos === undefined) {      segment.startTimeOffset.nanos = 0;    }    if (segment.endTimeOffset.seconds === undefined) {      segment.endTimeOffset.seconds = 0;    }    if (segment.endTimeOffset.nanos === undefined) {      segment.endTimeOffset.nanos = 0;    }    console.log(      `\tStart: ${segment.startTimeOffset.seconds}` +        `.${(segment.startTimeOffset.nanos / 1e6).toFixed(0)}s`    );    console.log(      `\tEnd: ${segment.endTimeOffset.seconds}.` +        `${(segment.endTimeOffset.nanos / 1e6).toFixed(0)}s`    );  });});

Supported Node.js Versions

Our client libraries follow theNode.js release schedule.Libraries are compatible with all currentactive andmaintenance versions ofNode.js.

Client libraries targetting some end-of-life versions of Node.js are available, andcan be installed via npmdist-tags.The dist-tags follow the naming conventionlegacy-(version).

Legacy Node.js versions are supported as a best effort:

• Legacy versions will not be tested in continuous integration.
• Some security patches may not be able to be backported.
• Dependencies will not be kept up-to-date, and features will not be backported.

Legacy tags available

• legacy-8: install client libraries from this dist-tag for versionscompatible with Node.js 8.

Versioning

This library followsSemantic Versioning.

This library is considered to beGeneral Availability (GA). This means itis stable; the code surface will not change in backwards-incompatible waysunless absolutely necessary (e.g. because of critical security issues) or withan extensive deprecation period. Issues and requests againstGA librariesare addressed with the highest priority.
