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 this attribute is present, and the browser supports autoplay:

  • the video is automatically muted before autoplay starts
  • when the video is scrolled out of view, the video is paused
  • when the video is scrolled into view, the video resumes playback
  • when the user taps the video, the video is unmuted
  • if the user has interacted with the video (e.g., mutes/unmutes, pauses/resumes, etc.), and the video is scrolled in or out of view, the state of the video remains as how the user left it. For example, if the user pauses the video, then scrolls the video out of view and returns to the video, the video is still paused.

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.
