VideoTrack.label

The read-only VideoTrack property label returns a string specifying the video track's human-readable label, if one is available; otherwise, it returns an empty string.

Syntax

var videoTrackLabel = VideoTrack.label;

Value

A DOMString specifying the track's human-readable label, if one is available in the track metadata. Otherwise, an empty string ("") is returned.

For example, a track whose kind is "sign" might have a label such as "A sign-language interpretation.".

Example

This example returns an array of track kinds and labels for potential use in a user interface to select video tracks for a specified media element. The list is filtered to only allow certain track kinds through.

function getTrackList(el) {
  var trackList = [];
  const wantedKinds = [
    "main", "alternative", "commentary"
  ];

  el.videoTracks.forEach(function(track) {
    if (wantedKinds.includes(track.kind)) {
      trackList.push({
        id: track.id,
        kind: track.kind,
        label: track.label
      });
    }
  });
  return trackList;
}

The resulting trackList contains an array of video tracks whose kind is one of those in the array wantedKinds, with each entry providing the track's id, kind, and label.
