如何复现问题？ How to reproduce the problem?
使用 plugins: [xgplayerMp4] 后视频就不播放了，没有任何报错

播放器代码：

xgPlayerRef.current = new SimplePlayer({
        id: `video_play`,
        url: videoUrl,
        autoplay: false,
        fluid: true,
        playsinline: true,
        autoplayMuted: true,
        controls: false,
        videoConfig: {
          crossOrigin: "anonymous"
        },
        height: window.innerHeight,
        width: window.innerWidth,
        plugins: [Mp4Plugin],
        mp4plugin: {
          maxBufferLength: 5,
          minBufferLength: 2
        }
     })

您期望的播放器正常行为是？ What did you expect to happen?
引入插件可以正常播放视频

实际播放器的表现是？ What actually happened?
不播放，控制台也没有报错。
看日志 xgplayer 就输出了这个，页面没有 video
[xgplayer] setState state from:INITIAL to:READY
[xgplayer] setState state from:READY to:ATTACHING

注释掉插件后播放器就可以播放了

我试着把 mp4Plugin 换成 xgplayer-mp4-new 下可以播放

import { SimplePlayer } from 'xgplayer'
import Mp4Plugin from 'xgplayer-mp4-new'

const player = new SimplePlayer({
    // ...
    plugins: [Mp4Plugin]
    // ...
})

依赖版本

{
  "dependencies": {
    "xgplayer": "^3.0.0",
    "xgplayer-mp4": "^3.0.23",
    "xgplayer-mp4-new": "3.0.0-next.1"
  }
}

但是如果使用 xgplayer-mp4，始终会报如下错误

Uncaught (in promise) TypeError: Cannot read properties of null (reading 'getFragmentIdx')
    at _callee2$ (xgplayer-mp4.js?v=f266b20c:16810:33)

Screenshot

这里似乎是 xgplayer/packages/xgplayer-mp4/src /mp4Plugin.js 中 changeDefinition callback 无法读取 this.mp4，this.mp4没有被初始。
