Tho*_*yth 3 html css youtube youtube-api
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的风格(https://thomas-smyth.co.uk/),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,而是将其替换为Youtube视频.我开始减少我的网站中使用的模板,并将其剥离到我认为我可以得到它而不打破标题.
我在这个地方找到了一些代码来展示如何将Youtube视频设置为整个页面的背景,而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其服务器上托管视频.
我目前的代码:

我使用直接链接到视频流(仅限JS/CSS解决方案)创建了一个简单的Youtube视频背景示例.随意在JSfiddle上查看它.此外,您还可以将公共Google Image代理网址更新为任何公共或您自己的CORS代理.
var vid = "R3AKlscrjmQ",
streams,
video_focused = true,
video_tag = $("#video"),
video_obj = video_tag.get(0);
$.get("https://images"+~~(Math.random()*33)+"-focus-opensocial.googleusercontent.com/gadgets/proxy?container=none&url=https%3A%2F%2Fwww.youtube.com%2Fget_video_info%3Fvideo_id%3D" + vid, function(data) {
if (data) {
streams = parse_youtube_meta(data);
video_tag.attr({
src: streams['1080p'] || streams['720p'] || streams['360p']
});
document.addEventListener("visibilitychange", function() {
video_focused = !video_focused ? video_obj.play() : video_obj.pause();
});
} else {
$('pre').text('Youtube API Error');
}
});
function parse_youtube_meta(rawdata) {
var data = parse_str(rawdata),
streams = (data.url_encoded_fmt_stream_map + ',' + data.adaptive_fmts).split(','),
result = {};
$.each(streams, function(n, s) {
var stream = parse_str(s),
itag = stream.itag * 1,
quality = false,
itag_map = {
18: '360p',
22: '720p',
37: '1080p',
