Device selection sample about opentok-web-samples

Yes, we are working on a feature to replace the tracks. The issue is we have been waiting for browsers to support this feature. Now Chrome supports it too and so we are looking into it. For now you do have to unpublish and publish a whole new Publisher unfortunately.

That's a concern that you're getting black videos. Can you file your issue on Stackoverflow and we can find an answer for you there. https://stackoverflow.com/questions/tagged/tokbox+or+opentok

2.14 now has cycleVideo() which lets you switch between cameras without having to unpublish and publish again. https://tokbox.com/developer/sdks/js/reference/Publisher.html#cycleVideo

This would be really nice, because I'm stuck with this atm.

I've created a stream using OT.getUserMedia and I'm passing those tracks into a new OT.Publisher. The problem is when I unpublish this publisher destroy it and create a new one with different tracks then it doesn't publish anymore. I'm just getting black videos.

I'd like if I didn't need to unpublish the publisher at all but I couldn't find a way how to add and remove tracks from the publisher.

Here is what happens to me:

Here are some code samples.

startStreaming () {
  const { session, properties, errorHandler, publish } = this
  console.log('properties', properties)
  this.$nextTick(() => {
    this.publisher = OT.initPublisher(properties, errorHandler)
    this.publisher.on('streamCreated', this.handleStreamCreated)
    this.publisher.on('streamDestroyed', this.handleStreamDestroyed)
    this.publisher.on('audioLevelUpdated', this.handleAudioLevelChange)

    session.on('sessionConnected', publish)
    if (session.isConnected()) { publish() }
  })
},
publish () {
  this.session.publish(this.publisher, this.errorHandler)
},
stopStreaming () {
  this.session.off('sessionConnected')
  this.publisher.off('streamCreated')
  this.publisher.off('streamDestroyed')

  this.session.unpublish(this.publisher)
  if (this.publisher) {
    this.publisher.destroy()
  }
},

@aullman cool I'll put it on our roadmap!

@aullman we've just discovered that it's not possible to pass a new set of device ids. Unfortunately we cannot use this function.

When we use OT.getUserMedia, how do we disconnect the call without refreshing the page? It seems that session.disconnect(publisher) does not work when there is OT.getUserMedia.
