2.26.0 (December 14, 2022)

New Features

• The LocalAudioTrack and
  LocalVideoTrack classes now provide a
  new boolean property called isMuted, which lets you know if the audio or video source is currently providing raw media
  samples. The classes also emit muted and unmuted events if the value of isMuted toggles. The application can use
  these APIs to detect temporary loss of microphone or camera to other applications (ex: an incoming phone call on an iOS device),
  and update the user interface accordingly. (VIDEO-11360)

• The Room class provides a new method called refreshInactiveMedia,
  which restarts any muted local media Tracks, and plays any inadvertently paused HTMLMediaElements that are attached to
  local and remote media Tracks. This is useful especially on iOS devices, where sometimes your application's media may
  not recover after an incoming phone call. You can use this method in conjunction with the local media Track's isMuted
  property described previously to recover local and remote media after an incoming phone call as shown below. (VIDEO-11360)

  Vanilla JS

  html

  <button id="refresh-inactive-media" disabled>Refresh Inactive Media</button>

  js

  const { connect } = require('twilio-video');
  
  const room = await connect('token', { name: 'my-cool-room' });
  
  const $refreshInactiveMedia = document.getElementById('refresh-inactive-media');
  $refreshInactiveMedia.onclick = () => room.refreshInactiveMedia();
  
  const [{ track: localAudioTrack }] = [...room.localParticipant.audioTracks.values()];
  const [{ track: localVideoTrack }] = [...room.localParticipant.videoTracks.values()];
  
  const isLocalAudioOrVideoMuted = () => {
    return localAudioTrack.isMuted || localVideoTrack.isMuted;
  }
  
  const onLocalMediaMutedChanged = () => {
    $refreshInactiveMedia.disabled = !isLocalAudioOrVideoMuted();
  };
  
  [localAudioTrack, localVideoTrack].forEach(localMediaTrack => {
    ['muted', 'unmuted'].forEach(event => {
      localMediaTrack.on(event, onLocalMediaMutedChanged);
    });
  });
