视频实现blob加密

喜欢ヅ旅行 2023-01-13 09:32 103阅读 0赞

本文是利用腾讯云api和sdk进行视频的加密处理和播放，前提是视频都是放在腾讯云的云点播中，并且开启了防盗链，开启防盗链这里不做介绍。

腾讯云主要是对视频进行了blob加密，然后利用腾讯的超级播放器进行播放，加密后的视频路径变为：blob:https://console.cloud.tencent.com/6808765f-af9c-4940-96fe-60a607cb242d，可以防止复制链接下载。

媒资处理会产生费用，由腾讯云收取。

视频加密总共分两步：

1，对视频指定任务流模板，可以理解为加密操作。

2，播放时，获取视频的签名，可以理解为解密操作。

引入依赖：
