在Facebook嵌入式视频中设置自动播放时如何启用声音？ [英] how to enable sound when autoplay is set in facebook embedded video?
问题描述
您实际上可以使用 Facebook嵌入式视频播放器API 来控制您的网站中的嵌入式视频，例如在页面加载时取消静音。
请注意，这并不适用于嵌入视频通过< iframe> 标签。使用链接中提到的< div> 标签（或参见下面的示例）。
这是一个示例脚本我从链接中插入 my_video_player.unmute（）在 xfbml.ready 事件中。确保您提供正确的 FB appId 。
< html>
< head>
< title>您的网站标题< / title>
< / head>
< body>
<！ - 加载Facebook SDK for JavaScript - >
< div id =fb-root>< / div>
< script>
window.fbAsyncInit = function（）{
FB.init（{
appId：'{your-app-id}'，
xfbml：true，
version ：'v2.5'
}）;
//获取嵌入式视频播放器API实例
var my_video_player;
FB.Event.subscribe（'xfbml.ready'，function（msg）{
if（msg.type ==='video'）{
my_video_player = msg.instance;
my_video_player.unmute（）;
}
}）;
};
（function（d，s，id）{
var js，fjs = d.getElementsByTagName（s）[0];
if（d.getElementById（id） {return;}
js = d.createElement（s）; js.id = id;
js.src =//connect.facebook.net/en_US/sdk.js;
fjs.parentNode.insertBefore（js，fjs）;
}（document，'script'，'facebook-jssdk'））;
< / script>
<！ - 您的嵌入式视频播放器代码 - >
< div
class =fb-video
data-href =https://www.facebook.com/facebook/videos/10153231379946729/

I embedded a video from facebook in my website and i set it in autoplay, but the sound is muted unless you click the volume and it will play the sound.
You can actually use Facebook Embedded Video Player API to control your embedded video in your website, such as unmuting it on page load.
Take note that this doesn't work on embedding videos thru <iframe> tag. Use the <div> tag as mentioned in the link (or see sample below).
Here's a sample script I got from the link, with insertion of my_video_player.unmute() on xfbml.ready event. Make sure you provide the proper FB appId.
<html>
<head>
<title>Your Website Title</title>
</head>
<body>
<!-- Load Facebook SDK for JavaScript -->
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : '{your-app-id}',
xfbml : true,
version : 'v2.5'
});
// Get Embedded Video Player API Instance
var my_video_player;
FB.Event.subscribe('xfbml.ready', function(msg) {
if (msg.type === 'video') {
my_video_player = msg.instance;
my_video_player.unmute();
}
});
};
(function(d, s, id){
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) {return;}
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/sdk.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
</script>
<!-- Your embedded video player code -->
<div
class="fb-video"
data-href="https://www.facebook.com/facebook/videos/10153231379946729/"
data-width="500"
data-autoplay="true"
data-allowfullscreen="true"></div>
</body>
</html>
