Custom Video Track - iOS

  • You can create a Video Track using createCameraVideoTrack() method of VideoSDK class.
  • This method can be used to create video track using different encoding parameters, camera facing mode, and optimization mode.

Parameters

  • encoderConfig:

    • type: CustomVideoTrackConfig
    • required: false
    • default: h360p_w640p
    • You can chose from the below mentioned list of values for the encoder config.

note

Above mentioned encoder configurations are valid for both, landscape as well as portrait mode.

  • facingMode:

    • type: String
    • required: false
    • Allowed values : .front | .back
    • It will specify whether to use front or back camera for the video track.
  • multiStream

    • type: boolean
    • required: false
    • default: true
    • It will specify if the stream should send multiple resolution layers or single resolution layer.

  • To learn more about optimizations and best practices for using custom video tracks, follow this guide.
  • This parameter is only available from v2.0.6.

Returns

  • RTCVideoTrack

Example

guard let videoMediaTrack = try? VideoSDK.createCameraVideoTrack(
encoderConfig: .h720p_w1280p,
facingMode: .front,
multiStream:true
) else { return }

Custom Audio Track

  • You can create a Video Track using createAudioTrack() method of VideoSDK class.
  • This method can be used to create audio track using different noise configs.

Parameters

  • noiseConfig

    • noiseSuppression

      • type: Bool
      • required: false
      • If true, noise suppression would be turned on; otherwise, it would be off.
    • echoCancellation

      • type: Bool
      • required: false
      • If true, echo cancellation would be turned on; otherwise, it would be off.
    • autoGainControl

      • type: Bool
      • required: false
      • If true, autogain control would be turned on; otherwise, it would be off.
    • highPassFilter

      • type: Bool
      • required: false
      • If true, highpass filter would be turned on; otherwise, it would be off.

Returns

  • RTCAudioTrack

Example

guard
let audioMediaTrack = try? VideoSDK.createAudioTrack(
noiseConfig: noiseConfig(
noiseSupression: true,
echoCancellation: true,
autoGainControl: true,
highPassFilter: true
)
)
else { return }
