How to use PHP and Youpai Cloud API to realize the functions of transcoding and screenshotting video resources

Introduction:
In today's Internet era, the demand for video content is getting higher and higher. How to quickly , Efficiently utilizing video resources has become a concern for many developers. The Paiyun API provides video transcoding and screenshot functions, which can help developers quickly and flexibly process video resources. This article will introduce how to use PHP and Youpai Cloud API to realize the functions of transcoding and screenshots of video resources, and provide corresponding code examples.

1. Preparation
Before using Youpaiyun API, we need to apply for a Youpaiyun account and create a storage space.

2. Configure API key
In Youpaiyun website, enter the storage space management page, find the "Space Management" corresponding to the storage space, click to enter the "Basic Settings" page, and click on the "API API key information can be found in the "Interface" column. Record the API key information, we need to use it in the code.

3. Code Implementation
Using PHP and Youpai Cloud API to transcode and screenshot video resources needs to be done by sending an HTTP request and carrying the corresponding parameters.

1. Video transcoding
Youpaiyun provides a wealth of transcoding parameters, which can be set according to your own needs. The following is a sample code that implements the function of transcoding a video file into MP4 format:

<?php
// 又拍云存储空间名称
$bucketName = 'your_bucket_name';
// 又拍云操作员名称
$operatorName = 'your_operator_name';
// 又拍云操作员密码
$operatorPassword = 'your_operator_password';

// 待转码的视频文件名
$sourceFile = '/path/to/source/file.mp4';
// 转码后的文件名
$targetFile = '/path/to/target/file.mp4';

// 构造API请求
$data = array(
    'bucket_name' => $bucketName,
    'notify_url' => 'http://your_notify_url',
    'source' => $sourceFile,   // 待转码文件路径
    'tasks' => json_encode(array(
        array(
            'type' => 'video',
            'avopts' => '/s/1280x720/vb/1000k',   // 转码设置，这里将视频转换为1280x720分辨率、1000kbps的视频
            'save_as' => $targetFile  // 转码后的文件保存路径
        )
    ))
);

// 生成授权签名
$sign = base64_encode(hash_hmac('sha1', http_build_query($data), $operatorPassword, true));

// 添加签名到请求参数中
$data['sign'] = $sign;

// 发送HTTP POST请求
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://v0.api.upyun.com/'.$bucketName);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
curl_close($ch);

// 根据API返回值处理结果
$result = json_decode($response, true);
if ($result['status'] === 'success') {
    echo '视频转码成功';
} else {
    echo '视频转码失败：'.$result['message'];
}
?>

2. Video screenshots
Youpaiyun provides a wealth of screenshot parameters, which can be customized according to your own needs. set up. The following is a sample code that implements the function of taking screenshots of video files:

<?php
// 又拍云存储空间名称
$bucketName = 'your_bucket_name';
// 又拍云操作员名称
$operatorName = 'your_operator_name';
// 又拍云操作员密码
$operatorPassword = 'your_operator_password';

// 待截图的视频文件名
$sourceFile = '/path/to/source/file.mp4';
// 截图后的图片文件名
$targetFile = '/path/to/target/file.jpg';

// 构造API请求
$data = array(
    'bucket_name' => $bucketName,
    'notify_url' => 'http://your_notify_url',
    'source' => $sourceFile,   // 待转码文件路径
    'tasks' => json_encode(array(
        array(
            'type' => 'image',
            'save_as' => $targetFile,  // 截图后的图片保存路径
            'op' => 'vframe',   // 操作类型为截图
            'args' => '/s/1280x720',    // 截图设置，这里将截取视频的1280x720分辨率的一帧图片
        )
    ))
);

// 生成授权签名
$sign = base64_encode(hash_hmac('sha1', http_build_query($data), $operatorPassword, true));

// 添加签名到请求参数中
$data['sign'] = $sign;

// 发送HTTP POST请求
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://v0.api.upyun.com/'.$bucketName);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
curl_close($ch);

// 根据API返回值处理结果
$result = json_decode($response, true);
if ($result['status'] === 'success') {
    echo '截图成功';
} else {
    echo '截图失败：'.$result['message'];
}
?>

IV. Summary
With the help of PHP and Youpai Cloud API, we can quickly implement the transcoding and screenshot functions of video resources. Let us make better use of video resources to meet the needs of different scenarios. In actual use, we can also customize more parameter settings according to specific business needs to achieve richer functions. Hope this article helps you!
