Real time streaming by using IVS Stage

0

In the context of our server side composition for broadcasting stage to an IVS channel, how can we display the participant's name when they choose to hide their camera?

One way to accomplish this is to create a separate LocalStageStream and swap to that instead of calling setMuted.

toggleCamMute() {
  if (!this.isCamMuted) {
    const canvas = document.createElement('canvas');
    canvas.width = 1280;
    canvas.height = 720;
    const ctx = canvas.getContext("2d");
    ctx.font = "30px Arial";
    ctx.fillStyle = "white";
    ctx.textAlign = "center";
    ctx.fillText("Todd", canvas.width / 2, canvas.height / 2); // make text dynamic as necessary
    const stream = canvas.captureStream();
    this.mutedLocalVideoStream = new LocalStageStream(stream.getVideoTracks()[0]);
    console.log(this.mutedLocalVideoStream);
  }
  else {
    this.mutedLocalVideoStream = null;
  }
  //this.localVideoStream.setMuted(!this.isCamMuted); not necessary, we're swapping the source track instead
  this.isCamMuted = !this.isCamMuted;
  this.stage.refreshStrategy();
}

In your stage strategy, check for the isCamMuted flag and swap the video stream accordingly.

stageStreamsToPublish: () => {
  const videoTrack = this.videoStream.getVideoTracks()[0];
  const audioTrack = this.audioStream.getAudioTracks()[0];
  this.localAudioStream = new LocalStageStream(audioTrack);
  this.localVideoStream = new LocalStageStream(videoTrack);
  const streamsToPublish = [
    this.localAudioStream, 
    this.isCamMuted ? 
      this.mutedLocalVideoStream : this.localVideoStream
  ];
  return streamsToPublish;
}
