How can I replace RTMPStreamDelegate, AVMixerVideoOutputDelegate, AVMixerMetadataFaceOutputDelegate in 1.8.1?

[3i-ArlinKim]

Hello, I am currently updating to version 1.8.1 and am running into difficulties. It appears that it was previously using a very old version (maybe 1.0.0).

Previously, RTMPStreamDelegate, AVMixerVideoOutputDelegate, and AVMixerMetadataFaceOutputDelegate were used, but they cannot be found in 1.8.1.

Please tell me how I can access these.

rtmpStream.delegate     = self
rtmpStream.mixer.videoOutputDelegate        = self
rtmpStream.mixer.metadataFaceOutputDelegate = self

extension LiveViewController: RTMPStreamDelegate {
  func didPublishSufficientBW(_ stream: RTMPStream, withConnection: RTMPConnection) {
    bitrate = defaultBitrate
    stream.videoSettings[.bitrate] = bitrate
  }
  
  func didPublishInsufficientBW(_ stream: RTMPStream, withConnection: RTMPConnection) {
    print("[Bitrate] Bad")
    bitrate = bitrate / 2
    stream.videoSettings[.bitrate] = bitrate
  }
  
  func clear() {
    bitrate = defaultBitrate
  }
  
  func didOutputAudio(_ buffer: AVAudioPCMBuffer, presentationTimeStamp: CMTime) {
    
  }
}
extension LiveViewController: AVMixerVideoOutputDelegate {
  func didOutputVideo(_ buffer: CMSampleBuffer) {
    guard mTrackingMode == .object else { return }
    
    guard !ot_isTrackerProcessing,
      let imageBuffer = CMSampleBufferGetImageBuffer(buffer),
      let image = UIImage(pixelBuffer: imageBuffer) else {
        return
    }
    
    objectTrackingHandleFrame(image)
  }
}

extension LiveViewController: AVMixerMetadataFaceOutputDelegate {
  func didOutputMetadataFaceObjects(_ metadataFaceObjects: [AVMetadataFaceObject]) {
    guard mTrackingMode == .smart else { return }
    
    var faces = Array<(id:Int,frame:CGRect)>()
    
    for faceObject in metadataFaceObjects {
      if let transformedMetadataObject = previewLayer.transformedMetadataObject(for: faceObject) {
        let face:(id: Int, frame: CGRect) = (faceObject.faceID, transformedMetadataObject.bounds)
        faces.append(face)
      }
    }
    
    DispatchQueue.main.async { [weak self] in
      self?.handleDetectedFrame(didDetectFaces: faces)
    }
  }
}

I don't remember creating AVMixerVideoOutputDelegate or AVMixerMetadataFaceOutputDelegate and I'm not familiar with them. Could these be custom extensions?

You can use the equivalent functionality of RTMPStreamDelegate with RTMPConnectionDelegate.
