PHP

一：下載七牛雲SDK

composer require qiniu/php-sdk

二：php實現七牛雲demo

        }
        return false;
    }


}

將其中的accessKey，secretKey，bucket，url，pipeline引數換成你自己七牛雲賬號的資訊

三：簡單實現

1：實現上傳

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

2：獲取上傳的音視訊資訊

$file = '';//上傳七牛雲後檔名
$qiniu = new QiNiu();
$qiniu->getAvinfo($file);

3:獲取視訊指定幀圖片

$file = '';//上傳七牛雲後視訊名稱
$qiniu = new QiNiu();
$qiniu->getVideoImage($file);//其他引數參考demo

4:視訊處理(裁剪，文字水印，新增音訊)

$file = '';//上傳七牛雲後視訊名稱
$qiniu = new QiNiu();
$qiniu->avthumb($file);//其他引數參考demo
