open fun onVideoQualityChanged(participantId: String, prevQuality: VideoQuality, currentQuality: VideoQuality)
Called when the quality of this participant's camera that this device receives changes — the server switched to another simulcast layer, after Participant.setQuality, a viewport change or a change in bandwidth.
Reported only for a camera sent in several layers; a single-layer camera has one quality and never calls this.
Parameters
participant
the participant whose camera changed quality.
prev
the quality received before the change.
current
the quality received now.
