Answer 1

This is what I have used for the API IFrame video loop. I noticed that you must include "playlist:VIDEO_ID" parameter. and it works. This is my example

<script>
  // Load the IFrame Player API code asynchronously.
  var tag = document.createElement('script');
  tag.src = "https://www.youtube.com/player_api";
  var firstScriptTag = document.getElementsByTagName('script')[0];
  firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

  // Replace the 'ytplayer' element with an <iframe> and
  // YouTube player after the API code downloads.
  var player;

  function onYouTubePlayerAPIReady() {
    player = new YT.Player('ytplayer', {
      height: '390',
      width: '640',
      videoId: 'VIDEO_ID',
      playerVars: {
        playlist: 'VIDEO_ID',
        loop: 1
      }
    });
  }
</script>
