Availability | Stable |
Examples | Annotated code example for amp-video |
Supported Layouts | fill, fixed, fixed-height, flex-item, nodisplay, responsive |
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>
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.
