Resolution

ByteArk Player SDK for iOS supports both automatic Adaptive Bitrate Streaming (ABR) and manual resolution selection by the viewer.

Adaptive Bitrate Streaming (ABR)

By default, AVPlayer adjusts the resolution automatically based on network speed using HLS ABR.

Select a resolution via API

// List all resolutions
let resolutions: [ByteArkPlayerMediaResolution] = player.resolutions
// Current resolution
let current: ByteArkPlayerMediaResolution? = player.resolution
// Select a resolution
player.setResolution(resolutions[0])

Receive resolution-change events

override func playbackResolutionChanged(
  player: ByteArkPlayer,
  resolution: ByteArkPlayerMediaResolution?
) {
  super.playbackResolutionChanged(player: player, resolution: resolution)
  // Resolution changed
}

Note

For showing a resolution picker on Safari for iOS/iPadOS in a Web context, see the Web SDK's Apple Quality Switcher. On the native iOS SDK the player relies on AVPlayer's ABR.
