Camera flipping on Mobile devices

Moving https://github.com/versatica/mediasoup-demo/issues/16 to this repo.

Currently there is no way to flip a camera on a mobile device using mediasoup-client. I tried mediasoup-demo, and it didn’t work. The current workaround is to stop the tracks both on mediaStream and videoProducer:

Typescript example:

export const switchCamera = async (
  videoDevicesCycle: Iterator<MediaDeviceInfo>,
  videoStream: MediaStream,
  videoProducer: any
): Promise<MediaStream> => {
  const videoDevice = videoDevicesCycle.next().value

  videoStream!.getVideoTracks()[0].stop()
  videoProducer.track.stop()

  videoStream = await getStream(
    config.videoMediaStreamConstraints(videoDevice!.deviceId)
  )

  await videoProducer.replaceTrack(videoStream.getVideoTracks()[0])

  return videoStream
}
