oss imm视频解码（php）

根据提供的引用，OSS提供了一个名为IMM（Intelligent Media Management）的服务，可以对视频进行解码。下面是使用PHP SDK进行视频解码的示例代码：

<?php
require_once '<yourPath>/aliyun-php-sdk-core/Config.php';
require_once '<yourPath>/aliyun-php-sdk-imm/Imm/Request/V20170906/DecodeVideoRequest.php';

use Imm\Request\V20170906 as Imm;

$accessKeyId = '<yourAccessKeyId>';
$accessKeySecret = '<yourAccessKeySecret>';
$regionId = '<yourRegionId>';
$endpoint = '<yourEndpoint>';

$decodeVideoRequest = new Imm\DecodeVideoRequest();
$decodeVideoRequest->setProject('yourProject');
$decodeVideoRequest->setAccessKeyId($accessKeyId);
$decodeVideoRequest->setAccessKeySecret($accessKeySecret);
$decodeVideoRequest->setRegionId($regionId);
$decodeVideoRequest->setEndpoint($endpoint);
$decodeVideoRequest->setVideoUri('oss://yourBucket/yourObject');
$decodeVideoRequest->setTargetContainer('mp4');
$decodeVideoRequest->setTargetFileName('yourTargetFileName');

$response = $client->getAcsResponse($decodeVideoRequest);

print_r($response);
?>

其中，`<yourPath>`需要替换为你的SDK路径，`<yourAccessKeyId>`、`<yourAccessKeySecret>`、`<yourRegionId>`、`<yourEndpoint>`需要替换为你的OSS账号信息，`<yourBucket>`、`<yourObject>`需要替换为你要解码的视频在OSS上的存储路径，`<yourTargetFileName>`需要替换为你解码后的视频文件名。
