HTMLMediaElement.srcObject

The srcObject property of the HTMLMediaElement interface sets or returns the object which serves as the source of the media associated with the HTMLMediaElement. The object can be a MediaStream, a MediaSource, a Blob, or a File (which inherits from Blob).

Note: As of November 2017, browsers only support MediaStream. For MediaSource, Blob and File, you have to create a URL with URL.createObjectURL() and assign it to HTMLMediaElement.src. See below for an example.

Syntax

var sourceObject = HTMLMediaElement.srcObject;

HTMLMediaElement.srcObject = sourceObject;

Value

MediaStreamMediaSource, Blob, or File object (though see the compatibility table for what is actually supported).

Usage notes

Older versions of the Media Source specification required using createObjectURL() to create an object URL then setting src to that URL. Now you can just set srcObject to the MediaStream directly.

Examples

Basic example

In this example, a media source is assigned to a newly-created <video> element.

const mediaSource = new MediaSource();
const video = document.createElement('video');
video.srcObject = mediaSource;

Supporting fallback to the src property

The example below supports older browser versions that require you to create an object URL and assign it to src if srcObject isn't supported.

const mediaSource = new MediaSource();
const video = document.createElement('video');
// Older browsers may not have srcObject
if ('srcObject' in video) {
  video.srcObject = mediaSource;
} else {
  // Avoid using this in new browsers, as it is going away.
  video.src = URL.createObjectURL(mediaSource);
}
