Is there any way to set referer to youtube-iframe-api?

Question

I am developing a Chrome extension and I am using youtube-iframe-api.

The player that is made by below codes can play any videos except some limited(?) videos such as vevo.

function onYouTubeIframeAPIReady() { 
  player = new YT.Player('player', {
  height: '300px',
  width: '800px',
  videoId: 'RhU9MZ98jxo', 
  playerVars: {
    'origin': 'https://www.youtube.com',
    'wmode': 'opaque'
  },
  events: {
    'onReady': onPlayerReady,
    'onStateChange': onPlayerStateChange
  }
});
};

I added origin and wmode in playerVars because I had found some answers that they can solve the problem. But they did not work.

I am wondering that it is possible to play vevo videos with embed youtube player (iframe)

Answer 1

I managed to play a vevo video in w3schools' "Try it yourself" by using the example provided in the youtube API documentation:

<div id="player">
</div>

<script>
      // 2. This code loads the IFrame Player API code asynchronously.
      var tag = document.createElement('script');

      tag.src = "https://www.youtube.com/iframe_api";
      var firstScriptTag = document.getElementsByTagName('script')[0];
      firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

      // 3. This function creates an <iframe> (and YouTube player)
      //    after the API code downloads.
      var player;
      function onYouTubeIframeAPIReady() {
        player = new YT.Player('player', {
          height: '390',
          width: '640',
          videoId: 'tWQPbHXyoFQ',
          events: {
            'onReady': onPlayerReady,
            'onStateChange': onPlayerStateChange
          }
        });
      }

      // 4. The API will call this function when the video player is ready.
      function onPlayerReady(event) {
        event.target.playVideo();
      }

      // 5. The API calls this function when the player's state changes.
      //    The function indicates that when playing a video (state=1),
      //    the player should play for six seconds and then stop.
      var done = false;
      function onPlayerStateChange(event) {
        if (event.data == YT.PlayerState.PLAYING && !done) {
          setTimeout(stopVideo, 6000);
          done = true;
        }
      }
      function stopVideo() {
        player.stopVideo();
      }
    </script>

What happens when you try to play vevo videos? what errors or messages do you get?

As a youtube uploader, you have the option to deny a video from being embedded in other websites besides youtube, in these cases you can't really do anything about it.
