php实现七牛云相关操作

一：下载七牛云SDK

composer require qiniu/php-sdk

二：php实现七牛云demo

}

将其中的accessKey，secretKey，bucket，url，pipeline参数换成你自己七牛云账号的信息

三：简单实现

1：实现上传

$qiniu = new QiNiu();
$qiniu->upload($_FILES['file']);

2：获取上传的音视频信息

$file = '';//上传七牛云后文件名
$qiniu = new QiNiu();
$qiniu->getAvinfo($file);

3:获取视频指定帧图片

$file = '';//上传七牛云后视频名称
$qiniu = new QiNiu();
$qiniu->getVideoImage($file);//其他参数参考demo

4:视频处理(裁剪，文字水印，添加音频)

$file = '';//上传七牛云后视频名称
$qiniu = new QiNiu();
$qiniu->avthumb($file);//其他参数参考demo
