github twilio/twilio-video.js 1.3.0

1.3.0 (September 11, 2017)

New Features

  • twilio-video.js now features an API for setting and updating bandwidth
    constraints. When you connect to a Room, you can specify an optional
    maxAudioBitrate and an optional maxVideoBitrate, both in bits per second
    (bps). These values are set as hints for variable bitrate codecs, but will not
    take effect for fixed bitrate codecs.

For example, to connect with a maximum audio bitrate of 64 kilobits per
second and a maximum video bitrate of 500 kilobits per second:

  const room = await connect(token, {
    maxAudioBitrate: 64000,
    maxVideoBitrate: 500000
  });

You can also update your maxAudioBitrate and maxVideoBitrate while
participating in a Room. For example, to reset your maximum bitrates for audio
and video, you could set each to null:

  room.localParticipant.setParameters({
    maxAudioBitrate: null,
    maxVideoBitrate: null
  });

If you want to change only one value—for example, just the maximum video
bitrate—you can omit the other value. For example, to update only the maximum
video bitrate, leaving the maximum audio bitrate unchanged:

  room.localParticipant.setParameters({ maxVideoBitrate: 1000000 });
  • twilio-video.js now features an API for setting preferred codecs when
    publishing Tracks. When you connect to a Room, you can specify an optional
    preferredAudioCodecs array and an optional preferredVideoCodecs array.
    These are codec "preferences" because they will only be applied if your
    browser and the type of Room you are connected to support them. If a
    preference cannot be satisfied, we will fallback to the next best codec.

For example, to connect with a preferred video codec of H.264:

  const room = await connect(token, {
    preferredVideoCodecs: ['H264']
  });

You can also specify more than one preferred codec. For example, to connect
with a preferred audio codec of iSAC, falling back to Opus if iSAC is
unavailable:

  const room = await connect(token, {
    preferredAudioCodecs: ['isac', 'opus']
  });

Please refer to the API docs for more information on both of these features.
