PS: 本文内容 参考 微课网 实现方式进行展开

1. 根据 lessonId 作为 标识， 获取 mp4 ， 视频文件，以及 教师视角的视频文件

{
  "code": "0", # 接口校验成功码
  "message": "微课状态成功"， # 接口校验成功状态值
  "data": {
    "audioUrl": "http://bj.download.cycore.cn/edc_zhwk/2020/3/27/1/56/2e264328-3a75-4ec2-ac51-6fdb65544b7e_mp4b165385a-46f9-4c0a-a863-5fa2444129ae.mp3", # 不确定 为啥 微课 会返回该字段，有可能是字幕部分当成一个独立的 map3音频进行播放， 更方便控制字幕进度，待确认
    "videoUrl": "http://bj.download.cycore.cn/edc_zhwk/2020/3/27/1/56/2e264328-3a75-4ec2-ac51-6fdb65544b7e_mp4ba08b33d-64cb-4835-8fba-d3a47d4c5dbf.mp4", # 返回了对应的视频文件的链接地址(前端展示不需要下载该文件， 可以在线浏览)，
    "teacherVideoUrl": 'xxxxxxxx.mp4',   # 也可以同时再此返回， **教师视角** 的视频链接地址
    "videoContextId": "5ea676ec6acfa739e88320d7" # 该 id 也可以不用， 继续使用 **lessonId** 来获取，对应的 **字幕**， **课程描述** 等 文件， 
  }

2. 根据 lessonId 作为 标识， 获取 字幕信息和图片控制进度信息

{
"code": "0"
"msg": "success",
"data": {
    "textInfo":[ // 字幕内容， 数组内数据的顺序与视频的时间戳，必须匹配

3. 根据 lessonId 作为 标识， 获取 微课名称 等描述信息

{
  "code": "0",
  "data": {
    "phase": "04",
    "editionCode": "01",
    "gradeName": "七年级",

    "knowledge": "<em>中国现当代作家作品</em>",
    "subjectName": "语文"
  },
  "message": "微课访问成功"
}

4. 剪切 视频 功能 需要 java 或者 C++ 后台，使用 FFmpeg 工具，在前端出入 视频段的开始和结束的时间戳，进行视频file的操作。
