Include plugin:

Prepare your video in several formats like '.webm', '.mp4' for cross browser compatibility, also add a poster with `.jpg`, `.png` or `.gif` extension:

  path/
  ├── to/
  │   ├── video.mp4
  │   ├── video.ogv
  │   ├── video.webm
  │   └── video.jpg

Add data-vide-bg attribute with a path to the video and poster without extension, video and poster must have the same name. Add data-vide-options to pass vide options, if you need it. By default video is muted, looped and starts automatically.

  <div style="width: 1000px; height: 500px;"
    data-vide-bg="path/to/video" data-vide-options="loop: true, muted: false, position: 0% 0%">
  </div>

Also you can set extended path:

  <div style="width: 1000px; height: 500px;"
    data-vide-bg="mp4: path/to/video1, webm: path/to/video2, ogv: path/to/video3, poster: path/to/poster"
    data-vide-options="posterType: jpg, loop: true, muted: false, position: 0% 0%">
  </div>

<script>
    $('#myBlock').vide('path/to/video');
    $('#myBlock').vide('path/to/video', {
    ...options...
    });
    $('#myBlock').vide({
      mp4: path/to/video1,
      webm: path/to/video2,
      ogv: path/to/video3,
      poster: path/to/poster
    }, {
    ...options...
    });
    $('#myBlock').vide('extended path as a string', 'options as a string');
</script>

Below is a complete list of options and matching default values:

<script>
    {
      volume: 1,
      playbackRate: 1,
      muted: true,
      loop: true,
      autoplay: true,
      position: '50% 50%', // Similar to the CSS `background-position` property.
      posterType: 'detect', // Poster image type. "detect" — auto-detection; "none" — no poster; "jpg", "png", "gif",... - extensions.
      resizing: true, // Auto-resizing, read: https://github.com/VodkaBears/Vide#resizing
      bgColor: 'transparent', // Allow custom background-color for Vide div,
      className: '' // Add custom CSS class to Vide div
    }
</script>

<script>
    // Get instance of the plugin
    var instance = $('#yourElement').data('vide');

    // Get video element of the background. Do what you want.
    instance.getVideoObject();

    // Resize video background.
    // It calls automatically, if window resize (or element, if you will use something like https://github.com/cowboy/jquery-resize).
    instance.resize();

    // Destroy plugin instance
    instance.destroy();
</script>
