KSOptions.secondPlayerType = KSMEPlayer.self
playerView = IOSVideoPlayerView()
playerView.translatesAutoresizingMaskIntoConstraints = false
    playerView.topAnchor.constraint(equalTo: view.readableContentGuide.topAnchor),
    playerView.leftAnchor.constraint(equalTo: view.leftAnchor),
    playerView.rightAnchor.constraint(equalTo: view.rightAnchor),
    playerView.bottomAnchor.constraint(equalTo: view.bottomAnchor),

        self.playerView.updateUI(isLandscape: false)
    } else {
        self.navigationController?.popViewController(animated: true)

Setting up a regular video

playerView.set(url:URL(string: "http://baobab.wdjcdn.com/14525705791193.mp4")!)
playerView.set(resource: KSPlayerResource(url: url, name: name!, cover: URL(string: "http://img.wdjimg.com/image/video/447f973848167ee5e44b67c8d4df9839_0_0.jpeg"), subtitleURL: URL(string: "http://example.ksplay.subtitle")))

Multi-definition, with cover video

let res0 = KSPlayerResourceDefinition(url: URL(string: "http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")!,
                                      definition: "高清")
let res1 = KSPlayerResourceDefinition(url: URL(string: "http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")!,
                                      definition: "标清")
let asset = KSPlayerResource(name: "Big Buck Bunny",
                             definitions: [res0, res1],
                             cover: URL(string: "https://upload.wikimedia.org/wikipedia/commons/thumb/c/c5/Big_buck_bunny_poster_big.jpg/848px-Big_buck_bunny_poster_big.jpg"))
playerView.set(resource: asset)

Setting up an HTTP header

let options = KSOptions()
let definition = KSPlayerResourceDefinition(url: URL(string: "http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")!,
                                            definition: "高清",
                                            options: options)
let asset = KSPlayerResource(name: "Video Name",
                             definitions: [definition])
playerView.set(resource: asset)

Listening status change

// Listen to play time change
playerView.playTimeDidChange = { (currentTime: TimeInterval, totalTime: TimeInterval) in
    print("playTimeDidChange currentTime: \(currentTime) totalTime: \(totalTime)")

// Delegates
public protocol PlayerControllerDelegate: class {
    func playerController(state: KSPlayerState)
    func playerController(currentTime: TimeInterval, totalTime: TimeInterval)
    func playerController(finish error: Error?)
    func playerController(maskShow: Bool)
    func playerController(action: PlayerButtonType)
    // `bufferedCount: 0` indicates first time loading
    func playerController(bufferedCount: Int, consumeTime: TimeInterval)

Advanced Usage

  • Inherits PlayerView's custom play logic and UI.

    class CustomVideoPlayerView: IOSVideoPlayerView {
        override func updateUI(isLandscape: Bool) {
            super.updateUI(isLandscape: isLandscape)
            toolBar.playbackRateButton.isHidden = true
        override func onButtonPressed(type: PlayerButtonType, button: UIButton) {
            if type == .landscape {
                // Your own button press behaviour here
            } else {
                super.onButtonPressed(type: type, button: button)
  • Selecting Tracks

       override open func player(layer: KSPlayerLayer, state: KSPlayerState) {
            super.player(layer: layer, state: state)
            if state == .readyToPlay, let player = layer.player {
                let tracks = player.tracks(mediaType: .audio)
                let track = tracks[1]
                /// the name of the track
                let name = track.name
                /// the language of the track
                let language = track.language
                /// selecting the one
                player.select(track: track)
  • Set the properties in KSOptions

    open class KSOptions {
      /// 最低缓存视频时间
      public var preferredForwardBufferDuration = KSOptions.preferredForwardBufferDuration
      /// 最大缓存视频时间
      public var maxBufferDuration = KSOptions.maxBufferDuration

      public var isLoopPlay = KSOptions.isLoopPlay
      /// 是否自动播放,默认false

      /// seek完是否自动播放
      public var isSeekedAutoPlay = KSOptions.isSeekedAutoPlay
