VideoElement

AMD: require(["esri/layers/support/VideoElement"], (VideoElement) => { /* code goes here */ });
ESM: import VideoElement from "@arcgis/core/layers/support/VideoElement.js";
Class: esri/layers/support/VideoElement
Inheritance: VideoElement Accessor
Since: ArcGIS Maps SDK for JavaScript 4.24

Represents a video element referenced in the MediaLayer's source. MediaLayer can display videos that are supported by web browsers. Refer to the common codecs document for supported video types.

Coordinates of the image and video elements can be specified in any spatial reference and are projected to the view's spatial reference. The content is stretched linearly between the coordinates, therefore it’s recommended for the image or video to match the view’s spatial reference to align correctly, especially for content covering large areas like the entire earth.

// create a video element by setting video param to point to the video file url
// set the geographic location of the video file on the map using an extent
const element = new VideoElement({
  video: "https://arcgis.github.io/arcgis-samples-javascript/sample-data/media-layer/videos/hurricanes_aerosol-aug.mp4",
  georeference: new ExtentAndRotationGeoreference({
    extent: new Extent({
      xmin: -150,
      ymin: 1,
      xmax: 20,
      ymax: 80,
      spatialReference: {
        wkid: 4326
      }
    })
  })

The name of the class. The declared class name is formatted as esri.folder.className.

The geographic location of the image or video element to be placed on the map. The location can be set by either specifying extent and rotation of the element, the corner points of the bounding box, or by defining control points.

opacity

Property
opacity Number

The opacity of the element. This value can range between 1 and 0, where 0 is 100 percent transparent and 1 is completely opaque.

Default Value:1

type

Property
type Stringreadonly

The element type.

For VideoElement the type is always "video".

video

Property
video String |HTMLVideoElement

The video element to be added to the media layer's source. The video element can be URL string pointing the video for example.

const element = new VideoElement({
  video: "https://arcgis.github.io/arcgis-samples-javascript/sample-data/media-layer/videos/hurricanes_aerosol-aug.mp4",
