MediaTrackSupportedConstraints: restrictOwnAudio property

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The MediaTrackSupportedConstraints dictionary's restrictOwnAudio property is a read-only boolean value which is present (and set to true) in the object returned by MediaDevices.getSupportedConstraints() if and only if the user agent supports the restrictOwnAudio constraint. If the constraint isn't supported, it's not included in the list, so this value will never be false.

You can access the supported constraints dictionary by calling navigator.mediaDevices.getSupportedConstraints().

Value

This property is present in the dictionary (and its value is always true) if the user agent supports the restrictOwnAudio constraint. If the property isn't present, this property is missing from the supported constraints dictionary, and you'll get undefined if you try to access its value.

Examples

<div id="result"></div>

#result {
  font:
    14px "Arial",
    sans-serif;
}

const result = document.getElementById("result");
const supported =
  navigator.mediaDevices.getSupportedConstraints().restrictOwnAudio;
result.textContent = supported ? "Supported!" : "Not supported!";
