请提前帮助我.

解决方法

您正在反复初始化视频播放器,但我认为您只需要更改源代码.请尝试以下.
$(function(){
  
    $('.player-src').on('click',function(){
    
       var videosrc = $(this).attr('data-src');
       var myPlayer = videojs('#my_video_1');
       myPlayer.src([ 
      { type: "video/mp4",src: videosrc },{ type: "video/webm",{ type: "video/ogg",src: videosrc }]
      );
   });

});
<link href="https://vjs.zencdn.net/7.3.0/video-js.css" rel="stylesheet"/>
<script src="https://vjs.zencdn.net/7.3.0/video.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul >
  <li class="player-src"  src="/local/filename.mp4">play-video1</li>
  <li class="player-src"  src="https://vjs.zencdn.net/v/oceans.webm">play-video2</li>
  <li class="player-src"  src="/local/filename.mp4">play-video3</li>
  <li class="player-src"  src="https://vjs.zencdn.net/v/oceans.webm">play-video4</li>
  <li class="player-src"  src="/local/filename.mp4">play-video5</li>
</ul>

 <video id="my_video_1" class="video-js vjs-default-skin" width="640px" height="267px" controls       
                  data-setup='{ "aspectRatio":"640:267",2] }'>
</video>
