ampvideo

ampvideo refers to the AMP HTML component used to embed video content within Accelerated Mobile Pages (AMP). The standard implementation is the amp-video element, which must load its extension script for the page to render correctly. It is designed to offer fast, server-backed video playback on mobile devices while staying within the performance constraints of AMP.

The component supports common video delivery patterns, including width, height, layout, poster, and controls. Video sources can be provided via a src attribute or nested source elements (for example, mp4 or webm). Autoplay is allowed only when the video is muted, in line with AMP's autoplay rules. amp-video includes built-in behavior for loading optimization, such as lazy loading and reduced layout shifts, to improve perceived performance.

Using amp-video requires including the AMP extension in the document head and placing the amp-video tag in the body with its required attributes. A typical setup specifies width and height, a poster image, and one or more sources. The component provides a consistent, AMP-compliant player interface that works within the AMP runtime and adheres to AMP's performance and security constraints.

Limitations and considerations: amp-video is specific to AMP pages and may not support all features available in the native HTML video element or in advanced streaming setups. It relies on the AMP runtime and is subject to AMP policies, which can affect plugin support, analytics integration, and customization options.
