[英]HTML5 background video not playing
我使用的是非公開視頻-只是全尺寸播放的html視頻。 問題是它沒有播放mp4,而是使用默認圖像。 我在與索引相同的目錄中有mp4和webm。 這是我的html:
<div class="homepage-hero-module">
<div class="video-container">
<div class="filter"></div>
<video autoplay loop class="fillWidth">
<source src="Browsing.mp4" type="video/mp4" />Your browser does not support the video tag. I suggest you upgrade your browser.
<source src="Browsing.webm" type="video/webm" />Your browser does not support the video tag. I suggest you upgrade your browser.
</video>
<div class="poster hidden">
<img src="Browsing.jpg" alt="">
</div>
</div>
</div>
這是我的css:
.homepage-hero-module {
border-right: none;
border-left: none;
position: relative;
}
.no-video .video-container video,
.touch .video-container video {
display: none;
}
.no-video .video-container .poster,
.touch .video-container .poster {
display: block !important;
}
.video-container {
position: relative;
bottom: 0%;
left: 0%;
height: 100%;
width: 100%;
overflow: hidden;
background: #000;
}
.video-container .poster img {
width: 100%;
bottom: 0;
position: absolute;
}
.video-container .filter {
z-index: 100;
position: absolute;
background: rgba(0, 0, 0, 0.4);
width: 100%;
}
.video-container video {
position: absolute;
z-index: 0;
bottom: 0;
}
.video-container video.fillWidth {
width: 100%;
}
最后,我的JS:
$( document ).ready(function() {
scaleVideoContainer();
initBannerVideoSize('.video-container .poster img');
initBannerVideoSize('.video-container .filter');
initBannerVideoSize('.video-container video');
$(window).on('resize', function() {
scaleVideoContainer();
scaleBannerVideoSize('.video-container .poster img');
scaleBannerVideoSize('.video-container .filter');
scaleBannerVideoSize('.video-container video');
});
});
function scaleVideoContainer() {
var height = $(window).height() + 5;
var unitHeight = parseInt(height) + 'px';
$('.homepage-hero-module').css('height',unitHeight);
}
function initBannerVideoSize(element){
$(element).each(function(){
$(this).data('height', $(this).height());
$(this).data('width', $(this).width());
});
scaleBannerVideoSize(element);
}
function scaleBannerVideoSize(element){
var windowWidth = $(window).width(),
windowHeight = $(window).height() + 5,
videoWidth,
videoHeight;
console.log(windowHeight);
$(element).each(function(){
var videoAspectRatio = $(this).data('height')/$(this).data('width');
$(this).width(windowWidth);
if(windowWidth < 1000){
videoHeight = windowHeight;
videoWidth = videoHeight / videoAspectRatio;
$(this).css({'margin-top' : 0, 'margin-left' : -(videoWidth - windowWidth) / 2 + 'px'});
$(this).width(videoWidth).height(videoHeight);
}
$('.homepage-hero-module .video-container video').addClass('fadeIn animated');
});
}
基本上,我只是按照我下載視頻文件時Coverr的指示進行操作。 誰能看到為什么無法播放視頻?
我為您的代碼創建了一個Codepen ,它可以工作,但是您的圖像覆蓋了視頻。 我認為您打算將圖像放在<video>
元素中作為后備。
<video autoplay loop class="fillWidth">
<source src="Browsing.mp4" type="video/mp4" />
<source src="Browsing.webm" type="video/webm" />
<img src="Browsing.jpg" alt="">
</video>
