Question

请告诉我如何在与mediaelement.js相关的视频中插入字幕？

我写了这样的代码

HTML

 <head>
 <meta charset="UTF-8"/>
 <title>111</title>


  <script src = "skript/mu/jquery-3.3.1.min.js"> </script>
  <script src = "skript/mediaelement-and-player.min.js"> </script>
  <link rel = "stylesheet" href = "skript/mediaelementplayer.css" />
  <script src = "skript/mu/3.js"> </script>

 </head>


 <body>
  <video id="player" controls preload="metadata" >
  <source src="1.mp4" type="video/mp4">     
  <track label="rus" kind="subtitles" srclang="ru" src="sub/rus.vtt"/>
  <track label="eng" kind="subtitles" srclang="en" src="sub/eng.srt"/>
  </video>


  </body>

 </html>

3.js

jQuery(document).ready(function($) {

$('audio,video').mediaelementplayer({
});

});

但是尝试使用此代码插入字幕

var player = new MediaElementPlayer('#player');

const track = document.createElement('track');
track.kind = 'subtitles';
track.label = 'English';
track.src = 'sub/eng.vtt';
track.srclang = 'en';

 if (player.trackFiles !== null) {
player.trackFiles = [track];
}
player.findTracks();

player.loadTrack(0);

player.setTrack('mep_0_track_0_subtitles_en');

给出错误消息
