前端 - 客户端上传视频很大如何解决传输和阿里云上传oss视频截取图的问题？

Question

客户在手机APP上传视频过大，如何更好的上传到阿里云的OSS里面？阿里云OSS有接口提取视频第一针的图片吗？

Answer 1

可以参考点击右侧-->Laravel 阿里云 OSS 视频上传完整方案

一、Laravel 上传大视频到阿里云 OSS（推荐使用分片上传）Laravel 可以通过阿里云官方 SDK 或社区封装包来实现 OSS 上传。推荐使用 aliyuncs/oss-sdk-php。

安装 SDK：

composer require aliyuncs/oss-sdk-php

示例代码：分片上传视频

use OSS\OssClient;
use OSS\Core\OssException;

function multipartUpload($filePath, $objectName)
{
    $accessKeyId = '你的AccessKeyId';
    $accessKeySecret = '你的AccessKeySecret';
    $endpoint = '你的Endpoint';
    $bucket = '你的Bucket名称';

    try {
        $ossClient = new OssClient($accessKeyId, $accessKeySecret, $endpoint);
        $uploadId = $ossClient->initiateMultipartUpload($bucket, $objectName);

        $partSize = 5 * 1024 * 1024; // 每片5MB
        $uploadFile = $filePath;
        $uploadFileSize = filesize($uploadFile);
        $pieces = $ossClient->generateMultiuploadParts($uploadFileSize, $partSize);
        $uploadParts = [];

        foreach ($pieces as $i => $piece) {
            $fromPos = $piece[$ossClient::OSS_SEEK_TO];
            $toPos = $piece[$ossClient::OSS_LENGTH];
            $isLastPart = $piece[$ossClient::OSS_IS_LAST_PART];
            $uploadPart = fopen($uploadFile, 'r');
            fseek($uploadPart, $fromPos);
            $uploadParts[] = $ossClient->uploadPart($bucket, $objectName, $uploadId, [
                'partNumber' => ($i + 1),
                'uploadPart' => $uploadPart,
                'length' => $toPos,
            ]);
        }

        $uploadedParts = [];
        foreach ($uploadParts as $i => $eTag) {
            $uploadedParts[] = [
                'PartNumber' => ($i + 1),
                'ETag' => $eTag,
            ];
        }

        $ossClient->completeMultipartUpload($bucket, $objectName, $uploadId, $uploadedParts);
        echo "上传成功！";
    } catch (OssException $e) {
        echo "上传失败：" . $e->getMessage();
    }
}

二、提取视频第一帧图片（Laravel 生成 URL）

可以通过Laravel生成带 x-oss-process 参数的 URL：

$bucket = 'your-bucket';
$endpoint = 'oss-cn-region.aliyuncs.com';
$object = 'video.mp4';

$snapshotUrl = "https://{$bucket}.{$endpoint}/{$object}?x-oss-process=video/snapshot,t_0,f_jpg,w_800,h_600,m_fast";

如果是私有 Bucket，可以使用 SDK 生成签名 URL：
$signedUrl = $ossClient->signUrl($bucket, $object, 3600, 'GET', [
    'x-oss-process' => 'video/snapshot,t_0,f_jpg,w_800,h_600,m_fast'
]);
