Question

我尝试使用YouTube player demo生成视频自动播放和循环所需的代码。但只有自动播放工作，它不循环，并且演示视频也不起作用。这是我用过的代码。

<iframe class="embed-responsive-item" id="ytplayer" type="text/html" width="640" height="360" src="https://www.youtube.com/embed/M7lc1UVf-VE?&autoplay=1&loop=1&rel=0&showinfo=0&color=white&iv_load_policy=3" frameborder="0" allowfullscreen>
</iframe>

Answer 1

尝试添加playlist参数以及循环。对于播放列表，请将其值设置为当前视频ID。

<iframe class="embed-responsive-item"id="ytplayer" type="text/html" width="640" height="360" src="https://www.youtube.com/embed/M7lc1UVf-VE?&autoplay=1&loop=1&rel=0&showinfo=0&color=white&iv_load_policy=3&playlist=M7lc1UVf-VE"
      frameborder="0" allowfullscreen></iframe>

目前，loop参数仅在与播放列表参数一起使用时才在AS3播放器中有效。要循环单个视频，请将循环参数值设置为1，并将播放列表参数值设置为已在播放器API网址中指定的相同视频ID：

http://www.youtube.com/v/VIDEO_ID?version=3&loop=1&playlist=VIDEO_ID

接受的答案对我也不起作用。 2018年9月的解决方法（奖金：通过CSS为#yt-wrap设置宽度和高度，而不是在JS中对其进行硬编码）：

<div id="yt-wrap">
    <!-- 1. The <iframe> (and video player) will replace this <div> tag. -->
    <div id="ytplayer"></div>
</div>

<script>
  // 2. This code loads 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);

  // 3. This function creates an <iframe> (and YouTube player)
  //    after the API code downloads.
  var player;
  function onYouTubePlayerAPIReady() {
    player = new YT.Player('ytplayer', {
      width: '100%',
      height: '100%',
      videoId: 'VIDEO_ID',
      events: {
        'onReady': onPlayerReady,
        'onStateChange': onPlayerStateChange
      }
    });
  }

  // 4. The API will call this function when the video player is ready.
  function onPlayerReady(event) {
    event.target.playVideo();
    player.mute(); // comment out if you don't want the auto played video muted
  }

  // 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.
  function onPlayerStateChange(event) {
    if (event.data == YT.PlayerState.ENDED) {
      player.seekTo(0);
      player.playVideo();
    }
  }
  function stopVideo() {
    player.stopVideo();
  }
</script>

Answer 3

像这样使用原生” ，请确保也为播放列表使用相同的视频ID值。

例如，如果视频ID为SpongeBOB 那么网址将是这样的：

https://www.youtube.com/embed/ SpongeBOB ？playlist = SpongeBOB ＆loop = 1

以下是反应本机网络视图

中的实现

<WebView
  javaScriptEnabled={true}
  domStorageEnabled={true}
  mediaPlaybackRequiresUserAction={true}
  style={{ height:180, width:300,alignSelf:"center",alignContent:"center"}}
  source={{uri: 'https://www.youtube.com/embed/qD101Xlc5uw?playlist=qD101Xlc5uw&loop=1' }}
 />

Answer 4

'playlist': '<?php echo $youtube_video ?>'

在playerVars中。

例如完整代码：

<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:'100%',
          width: '100%',
          fitToBackground: true,  
          videoId: '<?php echo $youtube_video ?>',
          playerVars: { 
              'autoplay': 1, 
              'controls': 0,
              'autohide':1,
              'enablejsapi':1,
              'loop':1, 
              'disablekb':1, 
              'fs': 0, 
              'modestbranding': 0, 
              'showinfo': 0, 
              'color': 'white', 
              'theme': 'light', 
              'rel':0  ,
              'playlist': '<?php echo $youtube_video ?>'
          },
          events: {
            'onReady': onPlayerReady
          }
        });
      }

      // 4. The API will call this function when the video player is ready.
      function onPlayerReady(event) {
        event.target.playVideo();
        player.mute();
        player.setVolume(0);
        //player.setSize(1920, 1080);
        player.setLoop(true);
        player.setPlaybackQuality('hd1080');
      }

您的Html代码：

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

如果您想将视频保存在变量中，请使用：

<?php $youtube_video='C0DPdy98e4c';?>

Answer 5

我只想弄清楚：你需要播放playlist =“”来使用循环

src =“https://www.youtube.com/embed/peSfCy7HFrM?playlist=peSfCy7HFrM&loop=1;rel=0&autoplay=1&controls=0&showinfo=0”frameborder =“0”allowfullscreen＆gt ;

Answer 6

您需要添加 https://www.youtube.com/embed/VIDEO_ID?playlist=VIDEO_ID&loop=1

注意播放列表 = VIDEO_ID 是强制性的，并且设置为单个视频的视频 ID

所以在我的情况下，网址是

https://www.youtube.com/embed/C5tG7pztlb0?playlist=C5tG7pztlb0&loop=1&autoplay=1&controls=1&showinfo=0&mute=1

静音已开启显示信息已关闭显示控件已关闭自动播放已开启循环开启

Answer 7

这是嵌入式循环播放列表的另一个有效示例：

<iframe width="1019" height="573" src="https://www.youtube.com/embed/videoseries?list=PLDz-3V1_TIyhVYiJeGdqc9bjpAf9L9Zfq&amp;loop=1" frameborder="0" allow="accelerometer; autoplay " ;"="" =""="" encrypted-media;="" gyroscope;="" picture-in-picture"="" allowfullscreen=""></iframe>

Youtube iframe＆＃34; loop＆＃34;不起作用
