Make video fit 100% with any screen resolution
提问by Qwerty
I have a video with the following properties, Frame width: 1920 and Frame Height: 1080. I need its width and height to be 100% thus filling up the whole screen. And it needs to be responsive too. So far, I have this code :
我有一个具有以下属性的视频，帧宽度：1920 和帧高度：1080。我需要它的宽度和高度为 100%，从而填满整个屏幕。它也需要响应。到目前为止，我有这个代码：
<video class="hidden-xs hidden-sm hidden-md hidden-custom videosize embed-responsive-item" autoplay="autoplay" loop="loop">
<source src="~/Videos/myvideo.mp4" type="video/mp4" />
</video>
css:
css：
.videosize {
position:absolute;
z-index:-1;
top:0;
left:0;
width:100%;
height:100vh;
}
With the code above it fits perfectly with a 1680 x 1050 screen resolution, however with other resolution, it takes up 100% of the height then the width adjusts leaving white spaces on both sides.
使用上面的代码，它非常适合 1680 x 1050 的屏幕分辨率，但是在其他分辨率下，它会占据高度的 100%，然后调整宽度，在两侧留下空白。
Any idea ? Thanks.
任何的想法 ？谢谢。

So your CSS would be:
所以你的 CSS 将是：
.video-container {
position: absolute;
top: 0;
bottom: 0;
width: 100%;
height: 100%;
overflow: hidden;
}
.video-container video {
/* Make video to at least 100% wide and tall */
min-width: 100%;
min-height: 100%;
/* Setting width & height to auto prevents the browser from stretching or squishing the video */
width: auto;
height: auto;
/* Center the video */
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%,-50%);
}

HTML：
<div class="video-container">
<video>
<source src="~/Videos/myvideo.mp4" type="video/mp4" />

You can now use the object-fit property. This property has been designed especially to manage responsive size for <img>and <video>elements. It is now supported by all modern browsers.
您现在可以使用 object-fit 属性。此属性专为管理<img>和<video>元素的响应大小而设计。现在所有现代浏览器都支持它。
.videosize {
position: absolute;
z-index: -1;
top: 0;
left: 0;
width: 100%;
height: 100%;
object-fit: cover;
}

我设置了视频标签的高度，它解决了问题：
<video height="600" autoplay="true" loop="true" muted="true" plays-inline="" style="position: absolute; right: 0; top: 0; min-width:100%; z-index: -100; object-fit: cover;">

height: 100%;
overflow: hidden;
object-fit: fill;
}
.video-container video {

min-height: 100%;
width: auto;

Can you use an iframe?
你可以使用 iframe 吗？
/* Flexible iFrame */
.flexible-container {
position: relative;
padding-bottom: 56.25%;
padding-top: 30px;
height: 0;
overflow: hidden;
}
.flexible-container iframe,
.flexible-container object,
.flexible-container embed {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}<!-- Responsive iFrame -->
<div class="flexible-container">
<iframe src="URL" frameborder="0" style="border:0"></iframe>
</div>
