MediaDeviceInfo: label property
The label
readonly
property of the MediaDeviceInfo
interface returns a
string describing this device (for example
"External USB Webcam").
Only available during active MediaStream
use, or when persistent permissions have been granted.
Value
A string which describes the media device. For security reasons, the
label
is always an empty string (""
) if the user has not
obtained permission to use at least one media device, either by starting a stream from
the microphone or camera, or by persistent permissions being granted.
