MediaStreamTrack: readyState property - Web APIs | MDN
MediaStreamTrack: readyState property Baseline Widely available
The readyState
read-only property of the MediaStreamTrack
interface returns an enumerated value giving the status of the track.
It takes one of the following values:
"live"
which indicates that an input is connected and does its
best-effort in providing real-time data. In that case, the output of data can be
switched on or off using the MediaStreamTrack.enabled
property.
"ended"
which indicates that the input is not giving any more data and
will never provide new data.
