amp-video

Description A replacement for the HTML5 video tag; only to be used for direct HTML5 video file embeds.
Availability Stable
Examples Annotated code example for amp-video
Supported Layouts fill, fixed, fixed-height, flex-item, nodisplay, responsive

Behavior

The amp-video component loads the video resource specified by its src attribute lazily, at a time determined by the runtime. It can be controlled much the same way as a standard HTML5 video tag.

The amp-video component HTML accepts up to three unique types of HTML nodes as children - source tags, a placeholder for before the video starts, and a fallback if the browser doesn’t support HTML5 video.

source tag children can be used in the same way as the standard video tag, to specify different source files to play.

One or zero immediate child nodes can have the placeholder attribute. If present, this node and its children form a placeholder that will display instead of the video. A click or tap anywhere inside of the amp-video container will replace the placeholder with the video itself.

One or zero immediate child nodes can have the fallback attribute. If present, this node and its children form the content that will be displayed if HTML5 video is not supported on the user’s browser.

For example:

<amp-video width=400 height=300 src="https://yourhost.com/videos/myvideo.mp4"
    poster="myvideo-poster.jpg">
  <div fallback>
    <p>Your browser doesn’t support HTML5 video</p>
  </div>
  <source type="video/mp4" src="foo.mp4">
  <source type="video/webm" src="foo.webm">
</amp-video>

Attributes

src

Required if no <source> children are present. Must be HTTPS.

poster

The image for the frame to be displayed before video playback has started. By default the first frame is displayed.

autoplay

If present, the video will automatically start playback once rendered (if autoplay is supported by the browser). Autoplay, when supported, will automatically mute the video before auto playing.

controls

Similar to the video tag controls attribute - if present, the browser offers controls to allow the user to control video playback.

loop

If present, will automatically loop the video back to the start upon reaching the end.

muted (deprecated)

muted attribute is deprecated and no longer has any effect. autoplay attribute automatically controls the mute behavior.

Validation

See amp-video rules in the AMP validator specification.
