Idiomatic PHP client for Cloud Video Intelligence

Latest Stable Version Packagist

NOTE: This repository is part of Google Cloud PHP. Any support requests, bug reports, or development contributions should be directed to that project.

Allows developers to use Google video analysis technology as part of their applications. The REST API enables users to annotate videos stored locally or in Google Cloud Storage with contextual information at the level of the entire video, per segment, per shot, and per frame.

NOTE: This documentation covers the most recent stable release (V1). There is an additional beta release included in this component. To check out its documentation, see the link below:

Installation

To begin, install the preferred dependency manager for PHP, Composer.

Now to install just this component:

$ composer require google/cloud-videointelligence

Or to install the entire suite of components at once:

$ composer require google/cloud

This component supports both REST over HTTP/1.1 and gRPC. In order to take advantage of the benefits offered by gRPC (such as streaming methods) please see our gRPC installation guide.

Authentication

Please see our Authentication guide for more information on authenticating your client. Once authenticated, you'll be ready to start making requests.

Sample

require __DIR__ . '/vendor/autoload.php';

use Google\Cloud\VideoIntelligence\V1\VideoIntelligenceServiceClient;
use Google\Cloud\VideoIntelligence\V1\Feature;

$videoIntelligenceServiceClient = new VideoIntelligenceServiceClient();

$inputUri = "gs://example-bucket/example-video.mp4";

$features = [
    Feature::LABEL_DETECTION,
];
$operationResponse = $videoIntelligenceServiceClient->annotateVideo([
    'inputUri' => $inputUri,
    'features' => $features
]);
$operationResponse->pollUntilComplete();
if ($operationResponse->operationSucceeded()) {
    $results = $operationResponse->getResult();
    foreach ($results->getAnnotationResults() as $result) {
        echo 'Segment labels' . PHP_EOL;
        foreach ($result->getSegmentLabelAnnotations() as $labelAnnotation) {
            echo "Label: " . $labelAnnotation->getEntity()->getDescription()
                . PHP_EOL;
        }
        echo 'Shot labels' . PHP_EOL;
        foreach ($result->getShotLabelAnnotations() as $labelAnnotation) {
            echo "Label: " . $labelAnnotation->getEntity()->getDescription()
                . PHP_EOL;
        }
        echo 'Frame labels' . PHP_EOL;
        foreach ($result->getFrameLabelAnnotations() as $labelAnnotation) {
            echo "Label: " . $labelAnnotation->getEntity()->getDescription()
                . PHP_EOL;
        }
    }
} else {
    $error = $operationResponse->getError();
    echo "error: " . $error->getMessage() . PHP_EOL;
