一：下载七牛云SDK
composer require qiniu/php-sdk
二：php实现七牛云demo

三：简略实现
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);//其余参数参考demo4:视频解决(裁剪，文字水印，增加音频)
$file = '';//上传七牛云后视频名称$qiniu = new QiNiu();$qiniu->avthumb($file);//其余参数参考demo
