HTMLMediaElement: crossOrigin property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The HTMLMediaElement.crossOrigin property is the CORS setting for this media element. See CORS settings attributes for details.

A string of a keyword specifying the CORS mode to use when fetching the resource. Possible values are:

anonymous or the empty string (""): Requests sent by the HTMLMediaElement will use the cors mode and the same-origin credentials mode. This means that CORS is enabled and credentials are sent if the resource is fetched from the same origin from which the document was loaded.
use-credentials: Requests sent by the HTMLMediaElement will use the cors mode and the include credentials mode. All resources requests by the element will use CORS, regardless of what domain the fetch is from.

If the crossOrigin property is specified with any other value, it is the same as specifing as the anonymous.

If the crossOrigin property is not specified, the resource is fetched without CORS (the no-cors mode and the same-origin credentials mode).
