How to play the desired video from the playlist in the YouTube player?

Question

Software players

Tell me how to play the desired clip in the playlist in the YouTube player. Here is the code for the player

<script src="https://www.youtube.com/iframe_api"></script>
    <div id="player"></div>
    <script>
       function onYouTubeIframeAPIReady() {
        player = new YT.Player('player', {
          height: '327',
          width: '530',
          playerVars: { 'autoplay': 1,'playlist':'OcqAUQ1vvic,bQrhRY3H7Hg,c-6A9rxQ9yU,qmSLX4mEC68', 'index': 1 }
        });
    }
 </script>

I need to start the player for example from 2 clips, how can I do this?
