How to solve the full screen error of H5 player in the layer pop-up layer

This article mainly introduces the method of solving the full-screen error of the H5 player in the layer pop-up layer & the attribute poster base image filling up the video. It has a very good reference value. Let’s take a look at it with the editor

In the layer pop-up component

If a flash player is used, full screen is normal

But If an HTML5 player is used, the full screen will fail

For example

<!DOCTYPE html>
<html>
<head>
 <meta charset="utf-8">
 <title></title>
 <script src="http://lib.sinaapp.com/js/jquery/1.9.1/jquery-1.9.1.min.js"></script>
 <script src="layer/layer.js"></script>
 <style>
 </style>
</head>
<body>
<h1>我是字</h1>
<p id="box">
<video id="video" controls preload="auto" width="400px" height="300px">
 <source src="http://movie.ks.js.cn/flv/other/1_0.mp4" type="video/mp4">
</video>
</p>
<script>
 layer.open({
 type: 1,
 title: false,
 shadeClose: true,
 area: [&#39;400px&#39;, &#39;350px&#39;],
 content: $(&#39;#box&#39;),
 success: function(layero){
 }
 });
</script>
</body>
</html>

You can see that the full screen is not normal

Through debugging, I found that the processing of this class affects the full screen display

#So, the current solution is to remove this class after the layer is created (note that it is placed in the next event loop in the success callback)

layer.open({
 type: 1,
 title: false,
 shadeClose: true,
 area: [&#39;400px&#39;, &#39;350px&#39;],
 content: $(&#39;#box&#39;),
 success: function(layero){
  console.log(layero)
  // hack处理layer层中video播放器全屏样式错乱问题
  setTimeout(function() {
  // $(layero).removeClass(&#39;layer-anim&#39;);
  }, 0);
 }
 });

video tag poster The attribute refers to a picture placed before the video is played

If the width and height of the video container is less than or equal to the width and height of the poster image, the picture can fill the container, otherwise black bars will be reserved on the left and right sides of the container

In addition to manually changing a large image, it can be controlled with CSS to achieve full coverage.

For example

<p id="box">
 <video id="video" controls preload="auto" width="700" height="300" poster="../poster.png" >
  <source src="http://movie.ks.js.cn/flv/other/1_0.mp4" type="video/mp4">
 </video>
</p>

Now the image width is smaller than the container and is not full. Refer to the discussion here to use CSS to expand it (this is equivalent to enlarging it. If you don’t want to enlarge it, you need to change the larger image yourself)

Put a transparent image in the poster (a 1px*1px base64 format transparent image is used here), and then use css to define the background of the video and cover it

<p id="box">
 <video id="video" controls preload="auto" width="700" height="300" poster="data:image/gif;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVQImWNgYGBgAAAABQABh6FO1AAAAABJRU5ErkJggg==" >
  <source src="http://movie.ks.js.cn/flv/other/1_0.mp4" type="video/mp4">
 </video>
</p>

video {
  background: transparent url(&#39;../poster.png&#39;) no-repeat 0 0; 
  -webkit-background-size: cover; 
   -moz-background-size: cover; 
    -o-background-size: cover; 
    background-size: cover; 
 }
