How to use PHP and Youpai Cloud API to realize the transcoding and streaming functions of audio and video

Introduction:
With the continuous development of network technology, the application of audio and video is becoming more and more widespread, and people are interested in audio and video. Video needs are also becoming more and more diverse. To realize the transcoding and streaming functions of audio and video, we can use the API provided by Youpaiyun and the programming capabilities of PHP to complete it. This article will introduce how to use PHP and Youpai Cloud API to implement audio and video transcoding and mixing functions, and provide corresponding code examples.

1. Preparation

Before we start, we need to install the PHP development environment and ensure that we can access Youpaiyun's API. At the same time, we also need to obtain Youpaiyun’s API key (BucketName, Operator, Password). In the code, we need to introduce PHP SDK, which can be introduced in the following ways:

require_once '又拍云 PHP SDK 路径/upyun.php';

2. Audio and video transcoding

Youpaiyun provides a powerful audio and video transcoding function, which can Convert audio and video files in different formats into target formats to meet different needs. The following is a code example for audio and video transcoding using PHP and Youpai Cloud API:

<?php
// 定义又拍云的API密钥
$bucketname = 'your_bucketname';
$operator = 'your_operator';
$password = 'your_password';

// 初始化又拍云对象
$upyun = new Upyun($bucketname, $operator, $password);

// 设置源文件和目标文件路径
$source = '/path/to/source/video.mp4';
$target = '/path/to/target/video.flv';

// 设置转码参数
$params = array(
    'bucket_name' => $bucketname,
    'source' => $source,
    'targets' => array(array('save_as' => $target, 'avopts' => '/s/360p/flv')))
);

// 发起转码请求
$response = $upyun->put('/transcoding/tasks', json_encode($params), 'application/json');

Through the above code, we can transcode the source file in the specified path into the target format and save it to the specified path. Among them, $source represents the source file path, $target represents the target file path, and avopts represents the transcoding parameters, which can be adjusted according to specific needs.

3. Audio and video mixing

Youpaiyun also provides an audio and video mixing function, which can merge multiple audio and video files into one audio and video file. The following is a code example for using PHP and Youpai Cloud API to implement audio and video mixing:

<?php
// 定义又拍云的API密钥
$bucketname = 'your_bucketname';
$operator = 'your_operator';
$password = 'your_password';

// 初始化又拍云对象
$upyun = new Upyun($bucketname, $operator, $password);

// 设置源文件和目标文件路径
$source1 = '/path/to/source/video1.mp4';
$source2 = '/path/to/source/video2.mp4';
$target = '/path/to/target/video.flv';

// 设置混流参数
$params = array(
    'bucket_name' => $bucketname,
    'sources' => array(
        array('path' => $source1),
        array('path' => $source2)
    ),
    'save_as' => $target
);

// 发起混流请求
$response = $upyun->put('/avmixer/tasks', json_encode($params), 'application/json');

Through the above code, we can merge different audio and video files into one audio and video file and save it to the specified path. Among them, $source1 and $source2 represent the two source file paths, and $target represents the target file path.

Conclusion:
Through the above code examples, we can realize the transcoding and mixing functions of audio and video. Through the combination of PHP and Youpai Cloud API, we can flexibly operate audio and video files to meet different business needs. At the same time, Youpaiyun provides rich functions and powerful performance support, providing developers with a more convenient and efficient development experience. I hope this article will be helpful in using PHP and Youpai Cloud API to implement audio and video transcoding and streaming functions.
