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demo4: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推荐阅读
