Moving from 1.8.x APIs to 1.9.0

FeatureUtil.setEnabled(for: .multiTrackAudioMixing, isEnabled: true)

1.8.0

FeatureUtil.setEnabled(for: .multiTrackAudioMixing, isEnabled: true)
let stream = RTMPStream(connection: rtmpConnection)

1.9.0

let stream = RTMPStream(connection: rtmpConnection)
stream.isMultiTrackAudioMixingEnabled = true

Multi Camera

1.8.0

stream.videoMixerSettings = IOVideoMixerSettings(
  mode: .pip,
  cornerRadius: 16.0,
  regionOfInterest: .init(
    origin: CGPoint(x: 16, y: 16),
    size: .init(width: 160, height: 160)
  ),
  direction: .east
)

1.9.0

I have revised the API to allow for flexible layout configurations.Advanced Video Editing feature. There may be times when you want to use CMSampleBuffer directly for custom video editing or ReplayKit data. In such cases, please use stream.videoMixerSettings.mode = .passthrough.

stream.videoMixerSettings.mode = .offscreen
stream.screen.size = .init(width: 720, height: 1280)
stream.screen.backgroundColor = UIColor.white.cgColor

videoScreenObject.cornerRadius = 16.0
videoScreenObject.track = 1
videoScreenObject.horizontalAlignment = .left
videoScreenObject.layoutMargin = .init(top: 16, left: 16, bottom: 0, right: 0)
videoScreenObject.size = .init(width: 160 * 2, height: 90 * 2)
try? stream.screen.addChild(videoScreenObject)

stream.screen.startRunning()

Apply VideoEffect

Up until version 1.8.x, VisualEffect was applied by default. Starting from version 1.9.0, it has been integrated as part of the Offscreen rendering API, so the following settings will be required.

1.8.0

// no op

1.9.0

stream.videoMixerSettings.mode = .offscreen
stream.screen.startRunning()
