PHP and Google Cloud Video Intelligence integration enables video content analysis and processing

As video media becomes more and more popular, the analysis and processing of video content has become a very hot topic in various fields. What follows is the need for video technology, and existing video processing tools no longer focus on the simple storage and display of video content, but focus on how to extract more useful information and data from videos. .

In this field, Google Cloud Video Intelligence is a very powerful and unique tool that can help users quickly analyze video content and extract useful information and data. PHP is a widely used scripting language, and many websites and applications are built using it. In this article, we will introduce how to integrate PHP and Google Cloud Video Intelligence to make it a very good video content analysis and processing tool.

1. Introduction to Google Cloud Video Intelligence

Google Cloud Video Intelligence is a cloud-based video analysis and processing platform that can help users quickly analyze video content and extract useful information and data. It supports a variety of video formats, including MP4, MOV, AVI, etc., and can extract useful information and data from a large number of videos in a few seconds, including video tagging, image tagging, brand recognition, text recognition, speech recognition, etc.

Google Cloud Video Intelligence provides multiple APIs that developers can use to develop custom applications and tools. Among them, the most commonly used APIs include:

1. Video tagging API: It can help users quickly analyze video content and convert scenes in the video into readable text tags to facilitate users to better understand the video. content.

2. Image tagging API: It can help users quickly analyze various images in videos and convert them into readable text tags to better understand the video content.

3. Brand recognition API: It can help users detect brands appearing in videos and convert them into readable text tags to facilitate users to better understand the video content.

4. Text recognition API: It can help users quickly analyze various texts appearing in videos and convert them into readable text tags to facilitate users to better understand the video content.

5. Speech recognition API: It can help users quickly identify various voice contents appearing in videos and convert them into readable text tags to facilitate users to better understand the video content.

2. Integration of PHP and Google Cloud Video Intelligence

Since PHP is a very popular scripting language, it is often used to build various websites and applications. Therefore, the integration of PHP and Google Cloud Video Intelligence will become a very good video content analysis and processing tool.

1. Create a Google Cloud Console project

First, you need to create a new project in the Google Cloud Console, during this process, provide the necessary API keys and credentials to the Google Cloud Console .

2. Download Google Cloud SDK and PHP client library

Next, you need to download Google Cloud SDK and PHP client library. You can get it by visiting the following link:

Google Cloud SDK: https://cloud.google.com/sdk/docs

PHP Client Library: https://github.com /googleapis/google-cloud-php

3. Configure Google Cloud SDK

After installing the Google Cloud SDK, you need to run the following command to configure the API key and credentials:

$ gcloud auth login

4. Create a Google Cloud Storage bucket

Next, you need to create a Google Cloud Storage bucket using the Google Cloud SDK, which will store your video files :

$ gsutil mb -l [REGION] gs://[BUCKET_NAME]

5. Use the PHP client library to access the Google Cloud Video Intelligence API

Now, you You can use the Google Cloud Video Intelligence API in the PHP client library to access Google Cloud Video Intelligence features, such as the video tagging API:

//Introducing dependencies
require 'vendor/autoload.php';

//Create client object
use GoogleCloudVideoIntelligenceV1VideoIntelligenceServiceClient;
$client = new VideoIntelligenceServiceClient();

//Create analysis request object
$inputUri = "gs:// [BUCKET_NAME]/[VIDEO_FILE]";
$features = [ "LABEL_DETECTION" ];
$options = [ "frameRate" => 30 ];
$context = [ "segmentLabel" => "my-segment" ];
$request = (new GoogleCloudVideoIntelligenceV1AnnotateVideoRequest())
->setInputUri($inputUri)
->setFeatures($features)
->setVideoContext((( new GoogleCloudVideoIntelligenceV1VideoContext())

->setSegmentLabel($context["segmentLabel"])
->setLabelDetectionConfig((new GoogleCloudVideoIntelligenceV1LabelDetectionConfig())
  ->setFrameConfidenceThreshold(0.4)
  ->setVideoConfidenceThreshold(0.5)
)

);

//Analyze the request and get the results
$response = $client->annotateVideo($request);

This code snippet will upload a video file and analyze it. You can also use other features such as image tagging API, brand recognition API, text recognition API, speech recognition API, etc.

3. Conclusion

Google Cloud Video Intelligence provides users with a fast and effective video content analysis and processing tool, enabling users to extract more useful information and data from videos. PHP is a widely used scripting language, and due to its popularity, we can build a very good video content analysis and processing tool through integration with the Google Cloud Video Intelligence API. By using this tool, users can easily extract useful information and data from videos and perform deeper analysis and processing.
