How PHP connects with Tencent Cloud audio and video analysis service to realize video content recognition function

With the rapid development of the Internet and digital media, video content recognition technology has received more and more attention. Tencent Cloud provides a powerful set of audio and video analysis services that can help developers realize intelligent identification and analysis of video content. This article will introduce how to use PHP to connect to Tencent Cloud audio and video analysis service to realize the function of video content recognition.

First of all, before we start, we need to register on the Tencent Cloud official website and create an audio and video analysis instance. Tencent Cloud will provide an interface key for each instance, and we need to save these keys for subsequent use.

Next, we need to install Tencent Cloud SDK in PHP. You can install it through Composer and run the following command:

composer require qcloudapi/qcloudapi-sdk-php

After the installation is complete, we can introduce the SDK and create a Tencent Cloud API object. The code example is as follows:

require_once 'vendor/autoload.php';

$config = array(
    'SecretId'       => 'YOUR_SECRET_ID',
    'SecretKey'      => 'YOUR_SECRET_KEY',
    'RequestMethod'  => 'POST',
    'DefaultRegion'  => 'ap-guangzhou',
    'Timeout'        => 10,
    'ConnectTimeout' => 10,
);

$api = QcloudApi::load(QcloudApi::MODULE_TCI, $config);

In the above code, replace YOUR_SECRET_ID and YOUR_SECRET_KEY with the interface key of the instance you obtained on the Tencent Cloud official website.

Next, we can call the API interface of Tencent Cloud Audio and Video Analysis Service to implement the video content recognition function. Taking content analysis of videos as an example, the code example is as follows:

$params = array(
    'url'                 => 'YOUR_VIDEO_URL',
    'callbackUrl'         => 'YOUR_CALLBACK_URL',
    'inputType'           => 1,
    'actionType'          => 0,
    'detectType'          => 0,
    'frameInterval'       => 100,
    'librarySet'          => array('porn', 'terrorism'),
    'needCallback'        => 1,
);

$response = $api->DescribeVideoTrend($params);

In the above code, replace YOUR_VIDEO_URL with the URL of the video you want to perform content analysis on, YOUR_CALLBACK_URLReplace with the callback URL you set.

Through the above code, we can call Tencent Cloud's audio and video analysis service to identify video content. The returned $response variable will contain information related to the recognition result.

It should be noted that Tencent Cloud audio and video analysis service provides a rich API interface, which can realize different types of audio and video content recognition functions. Developers can choose the appropriate interface according to their own needs.

This article introduces how to use PHP to connect to Tencent Cloud audio and video analysis service to realize the function of video content recognition. Tencent Cloud provides a powerful and easy-to-use API interface, so developers can easily implement multiple types of video content recognition. At the same time, Tencent Cloud also provides rich documentation and sample code, which developers can customize and expand according to their own needs. I hope this article can be helpful to everyone in implementing the video content recognition function.
