Youtube player api with loop

Question

I am struggling with setting up the loop for youtube videos using youtube player api.

The problem is that the video is not running under a loop.

Here is my code

var tag = document.createElement('script');

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


      var player;
      function onYouTubeIframeAPIReady() {
        player = new YT.Player('player', {
          height: '390',
          width: '640',

          playerVars: {
            'controls': 0,           
            'showinfo': 0,
            'rel': 0,
            'loop': 1

          },
          videoId: 'qzZuBWMnS08',
          events: {
            'onReady': onPlayerReady,
           // 'onStateChange': onPlayerStateChange
          }
        });
      }
function onPlayerReady(event) {
        //  event.target.setLoop(true);
        event.target.playVideo();
      }

The loop:1 doesn't seem to be working.Also is there any way to remove the share and video title from the top of the video.

Thanks in advance.

Answer 1

If the video isn't changing, you can just do

onStateChange: 
    function(e) {
        if (e.data === YT.PlayerState.ENDED) {
            player.playVideo(); 
        }
    }

This will prevent unnecisarily reloading the video

Answer 2

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>

Answer 3

As stated in the documentation, you need to set the playlist parameter to the video ID in order for loop to work.

You'll be wanting the showinfo parameter to hide the title etc.

Answer 4

Try this in your onPlayerStateChange, in some sort of way Youtube wants you to put in the videoID again.

onStateChange: function(e){
    var id = 'qzZuBWMnS08';

    if(e.data === YT.PlayerState.ENDED){
        player.loadVideoById(id);
    }
}

I got this to work to give me loop video with super low volume set for playing video. You can mute by changing volume from 2 to 0.

Also make sure your video is added to a playlist. Apparently that is an issue now. And use video id in both playlist and videoid areas in the code.

Im sure i have extra steps or redundant steps as im no coder.

I just know this works.

    <div id="player">
<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: '315',
          width: '600',
          videoId: 'DrrH-YTvVVc',
          playerVars: {
          playlist: 'DrrH-YTvVVc',
          loop: 1      }       ,
   events: {
            'onReady': onPlayerReady,
            'onStateChange': onPlayerStateChange
          }
        });
      }
      // 4. The API will call this function when the video player is ready.
      function onPlayerReady(event) {
           event.target.setVolume(2);
       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 = true;
      function onPlayerStateChange(event) {
        if (event.data == YT.PlayerState.ENDED) {
    //      setTimeout(stopVideo, 6000);
                  player.playVideo();
        }
           event.target.setVolume(2);
      }
</script></div>

Working loop example (02-2019)

<div id="ytplayer">
<script>
  var tag = document.createElement('script');
  tag.src = "https://www.youtube.com/player_api";
  var firstScriptTag = document.getElementsByTagName('script')[0];
  firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
  var player;
  function onYouTubePlayerAPIReady() {
    player = new YT.Player('ytplayer', {
      width: '640',
      height: '360',

          // 1. Video_Id
          videoId: 'AfAwsdbj04I',

      playerVars: { 
          autoplay: 1,
          loop: 1,
          controls: 0,
          rel: 0,
          modestbranding: 1,

          // 2. Playlist_Id (don't forget "PL")
          playlist: 'PLxWQS97ZR2-_c2eqKxSHxEu7v462-qnYM'

      },
      events: {
        'onReady': onPlayerReady,
        'onStateChange': onPlayerStateChange
      }
    });
  }
  function onPlayerReady(event) {
    event.target.setVolume(80);
    event.target.playVideo();
 //  player.mute();
  }
  function onPlayerStateChange(event) {
    if (event.data == YT.PlayerState.ENDED) {
      player.seekTo(0);
      player.playVideo();
    }
  }
  function stopVideo() {
    player.stopVideo();
  }
</script>
</div>

Since the html5 player, we can just right click on the video => play in loop.

From script, to replay at the end of the video:

document.getElementsByClassName('video-stream html5-main-video')[0].loop = true

Loop 1.66 seconds between two time points:

const video = document.getElementsByClassName('video-stream html5-main-video')[0]

/* Loop markers in seconds */
let start = 54.34, end = 56

/* Seek to time in seconds */
function seek(time){
  video.loop = true
  video.currentTime = time
  video.play()
}

/* Loop between start and end */
function loop(e){
  if (e.target.currentTime > end){
    seek(start)
  }
}

/* Will loop for 1.66s */
video.addEventListener("timeupdate", loop, false)

/* Seek to 54.34s */
seek(start)

/* Abort the loop */
// video.removeEventListener("timeupdate", loop, false)

/* New loop */
// start = 14; end = 15; seek(start)
