如何以低音量(iframe)自动启动Youtube VIDEO [英] How to Autostart Youtube VIDEO with Low Volume (iframe)

问题描述

这是我创建的iframe，用于自动启动博客中的视频(主要是音乐):

This is the iframe I create to autostart a video (music, mostly) in my blog :

< iframe width="140" height="105" src="https://www.youtube.com/embed/tGzl_AB4poI?rel=0&amp;showinfo=0&autoplay=1" frameborder="0" allowfullscreen></iframe>

一切都很完美.唯一的问题是音频，因为音量太高，我会降低音量-所以我在代码中添加了这部分:& player.setVolume(5)"

It's all perfect. The only problem is the Audio, because the Volume is too high and I would decrease it- So I added this part on my code : "&player.setVolume(5)"

那么，最后的代码就是这个:

The final code, then, is this one:

< iframe width="140" height="105" src="https://www.youtube.com/embed/tGzl_AB4poI?rel=0&amp;showinfo=0&autoplay=1&player.setVolume(5)" frameborder="0" allowfullscreen></iframe>

问题在于它无法正常工作，而且Volume仍然是默认的-(但是代码仍可与自动播放和所有其他偏好一起使用).

The problem is that it wont works and the Volume is still the deafault one- (but the code still works with autoplay and all other pref).

出了什么问题?

推荐答案

在 IFrame API参考，您可以使用 player.setVolume()设置播放器之后的音量准备好了.

In IFrame API reference, you can use player.setVolume() to set the volume after the player is ready.

如果要控制音量，则必须使用Javascript编写一些代码:

If you want to control the volume, you have to write some code in Javascript:

function onYouTubeIframeAPIReady() {
  // iframeId parameter should match your Iframe's id attribute
  var player = new YT.Player('iframeId', {
    width: 140,
    height: 105,
    videoId: 'tGzl_AB4poI',
    events: {
      'onReady': function (event) {
        event.target.setVolume(0);
        event.target.playVideo();
      }
    }
  });
}
