Audio Track

ByteArk Player SDK for iOS supports selecting an audio track when the video has multiple audio languages. Viewers can pick via the player UI or through the API.

Select an audio track via API

// List all audio tracks
let audios: [ByteArkPlayerMediaTrack] = player.audioTracks
// Current audio track
let current: ByteArkPlayerMediaTrack? = player.audioTrack
// Select an audio track
player.setAudioTrack(audios[0])

Receive audio-track change events

override func playbackAudioTrackChanged(
  player: ByteArkPlayer,
  audioTrack: ByteArkPlayerMediaTrack?
) {
  super.playbackAudioTrackChanged(player: player, audioTrack: audioTrack)
  // Audio track changed
}
