我正在尝试创建一些网站模板来帮助我提高我的前端开发技能，因为我目前在后端工作方面要好得多。

我试图在某种程度上复制我自己网站 ( https://thomas-smyth.co.uk/ ) 的风格，这是一个简单的 Bootstrap 模板。但是，我不想在标题中使用静态照片，而是想用 Youtube 视频替换它。我首先减少了我网站中使用的模板，并将其精简到我认为我可以在不破坏标题的情况下获得的尽可能少的模板。

我在这个地方找到了几段代码，展示了如何将 Youtube 视频设置为整个页面的背景，但不是页面特定部分的背景。我怎样才能做到这一点？注意 - 它必须从 YouTube 流式传输，因为我的主机不允许我在他们的服务器上托管视频。

我当前的代码:

<!DOCTYPE html>
<html>

<head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <!-- Tell the browser to be responsive to screen width -->
    <meta content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no" name="viewport">

    <title>Group Name | Home</title>

    <!-- Bootstrap 3.3.6 -->
    <link rel="stylesheet" href="dist/bootstrap/css/bootstrap.min.css">
    <!-- Font Awesome -->
    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.5.0/css/font-awesome.min.css">
    <!-- Ionicons -->
    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/ionicons/2.0.1/css/ionicons.min.css">

    <!-- Custom -->
    <link rel="stylesheet" href="dist/css/mainstyle.css">

</head>

<body>

    <header>
        <div class="header-content">
            <div class="header-content-inner">
                <h1>This is going once vid is done.</h1>
            </div>
        </div>
    </header>

    <section class="bg-primary">
        <div class="container">
            <div class="row">
                <div class="col-lg-8 col-lg-offset-2 text-center">
                    <h2 class="section-heading">Placeholder!</h2>
                    <p>I should have found a witty comment to put here, but I'm just gonna put "Placeholder" instead.</p>
                </div>
            </div>
        </div>
    </section>

最佳答案

我使用直接链接到视频流(仅 JS/CSS 解决方案)创建了一个带有 Youtube 视频背景的简单示例。随时查看 JSfiddle .此外，您可以将公共(public) Google 图像代理 URL 更新为任何公共(public)或您自己的 CORS 代理。

var vid = "FUUw3zNTXH8",
    streams,
    video_tag = document.getElementById("video");

fetch("https://images" + ~~(Math.random() * 33) + "-focus-opensocial.googleusercontent.com/gadgets/proxy?container=none&url=" + encodeURIComponent("https://www.youtube.com/watch?hl=en&v=" + vid)).then(response => response.text()).then(function(data) {
    if (data) {
        streams = parse_youtube_meta(data);
        video_tag.src = streams['hls'] || streams['720pna'] || streams['480pna'] || streams['720p'] || streams['480p'] || streams['360p'] || streams['240p'] || streams['144p'];
    } else {
        alert('Youtube API Error');
    }
});

function parse_youtube_meta(rawdata) {


    var regex = /(?:ytplayer\.config\s*=\s*|ytInitialPlayerResponse\s?=\s?)(.+?)(?:;var|;\(function|\)?;\s*if|;\s*if|;\s*ytplayer\.|;\s*<\/script)/gmsu;


    rawdata = rawdata.split('window.getPageData')[0];
    rawdata = rawdata.replace('ytInitialPlayerResponse = null', '');
    rawdata = rawdata.replace('ytInitialPlayerResponse=window.ytInitialPlayerResponse', '');
    rawdata = rawdata.replace('ytplayer.config={args:{raw_player_response:ytInitialPlayerResponse}};', '');


    var matches = regex.exec(rawdata);
    var data = matches && matches.length > 1 ? JSON.parse(matches[1]) : false;

    console.log(data);

    var streams = [],
        result = {};

    if (data.streamingData && data.streamingData.adaptiveFormats) {
        streams = streams.concat(data.streamingData.adaptiveFormats);
    }

    if (data.streamingData && data.streamingData.formats) {
        streams = streams.concat(data.streamingData.formats);
    }

    streams.forEach(function(stream, n) {
        var itag = stream.itag * 1,
            quality = false,
            itag_map = {
                18: '360p',
                22: '720p',
                37: '1080p',
                38: '3072p',
                82: '360p3d',
                83: '480p3d',
                84: '720p3d',
                85: '1080p3d',
                133: '240pna',
                134: '360pna',
                135: '480pna',
                136: '720pna',
                137: '1080pna',
                264: '1440pna',
                298: '720p60',
                299: '1080p60na',
                160: '144pna',
                139: "48kbps",
                140: "128kbps",
                141: "256kbps"
            };
        //if (stream.type.indexOf('o/mp4') > 0) console.log(stream);
        if (itag_map[itag]) result[itag_map[itag]] = stream.url;
    });

    if (data.streamingData && data.streamingData.hlsManifestUrl) {
        result['hls'] = data.streamingData.hlsManifestUrl;
    }

    return result;
};
html, body {
    height: 100%;
    min-height: 100%;
    background: #444;
    overflow: hidden;
}
video {
    width: 100%;
    height: 100%;
    object-fit: cover;
}
<video loop muted autoplay playsinline id="video"></video>
