MInIO入门-04 基于minio+ckplayer视频点播 实现

项目传送门

1、ckplayer（前端js播放器）

1.1、官网

https://www.ckplayer.com/

2、后台实现

2.1、参考博客

https://blog.csdn.net/waleit/article/details/117693364

2.2、通过request的Range来实现

2.3、后台代码

2.4、相关依赖代码见博客

https://blog.csdn.net/lyf_zm/article/details/124627842

3、测试使用

3.1、包结构

3.2、video.html

3.2.1、创建视频对象

// 创建视频对象
let videoObject = {
    container: '.video',//视频容器的ID
    volume: 0.8,//默认音量，范围0-1
    video: 'http://localhost:18002/video/play?bucketName=minio-test&objectName=488b4f54-a5be-4796-883c-954e0cd83742.mp4',//视频地址
};

// 调用播放器并赋值给变量player
let player = new ckplayer(videoObject)
