Make video fit 100% with any screen resolution

问题:

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 :

<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:

   .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.

Any idea ? Thanks.

Found a good solution here: http://codepen.io/shshaw/pen/OVGWLG

So your CSS would be:

.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" />
  </video>
</div>

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.

.videosize {
    position: absolute;
    z-index: -1;
    top: 0;
    left: 0;
    width: 100%; 
    height: 100%;
    object-fit: cover;
}

Can you use an iframe?

/* 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>

I Set the height of the video Tag and it solved the problem:

<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;">
      <source src="assets/vid/grapes.mp4" type="video/mp4"> </video>

.video-container {
        position: absolute;
        top: 0;
        bottom: 0;
        width: 100%;
        height: 100%;
        overflow: hidden;
        object-fit: fill;
    }

    .video-container video {
        min-width: 100%;
        min-height: 100%;
        width: auto;
        height: auto;
        position: absolute;
        top: 50%;
        left: 50%;
        transform: translate(-50%, -50%);
    }

This worked for me.
