    Declaration

    Swift

    var bufferedPercentage: Float? { get }

  • Initalise the AVPictureInPictureController and returns a reference of it.

    Remark

    Works only with PlayerEngine.apple. From our tests, the PiP playback becomes available on most devices when the player moves to PlaybackState.playing.

    Declaration

    Swift

    @available(tvOS 14.0, *)
func getPictureInPictureController() -> AVPictureInPictureController?

    Return Value

    An initiliazed AVPictureInPictureController object.

  • Indicates whether the player should continue the playback in the background. The default value is false.

    Besides setting this flag to true please add the UIBackgroundModes key in your app’s Info.plist file. Its value is an array that contains one or more strings that identify which background tasks your application supports. Specify the string value audio.

    Remark

    Works only for audio-only streams. Must be called before state .open.

    Declaration

    Swift

    var continueAudioPlaybackInBackground: Bool { get set }

  • A value of 1.0 (default) plays the current item at its natural rate. Setting to values lower than 1 slow down the playback; values higher than 1 speed it up.

    Remark

    Content played at playbackRate lower than 0.0 or higher than 2.0 will have audio muted.

    Remark

    Expects frame drops for high values.

    Remark

    Negative rates only work with PlayerEngine.apple. The player will use the I-Frame playlist if present otherwise it would try to play it anyways (which usually result in a sketcky playback). In both cases audio is muted.

    Declaration

    Swift

    var playbackRate: Double { get set }

  • The playback volume of the player instance, ranging from 0.0 through 1.0 on a linear scale. A value of 0.0 indicates silence; a value of 1.0 (the default) indicates full volume for the audio queue instance.

    Remark

    This value does not impact the device overall volume. Setting it at 1.0 (default) means: “play at the device current max volume”.

    Remark

    Must be called after the player transitions to PlaybackState.ready.

    Remark

    When used with PlayerEngine.apple, please consider this note from Apple: “Do not use this property to implement a volume slider for media playback. For that purpose, use MPVolumeView, which is customizable in appearance and provides standard media playback behaviors that users expect.

    This property is most useful on iOS to control the volume of the AVPlayer relative to other audio output, not for volume control by end users.

    Declaration

    Swift

    var playbackVolume: Double { get set }

  • Starts loading the content. The player will transition to PlaybackState.opening until it has enough meta-data loaded to build up a track model and then transition to PlaybackState.ready.

    Declaration

    Swift

    func open(autoplay: Bool)

    Parameters

    autoplay

    Whether the content shall start play automatically after the player reaches the PlaybackState.ready.

  • Start playback. The player will transition into PlaybackState.play and into PlaybackState.playing once the frames appear on screen. Calling this method when player is PlaybackState.idle is equivalent to open(autoplay:true).

    Declaration

    Swift

    func play()

  • Pause playback. The player will transition into PlaybackState.pausing and then into PlaybackState.paused once the frames pause on screen.

    Declaration

    Swift

    func pause()

  • Stop playback. The player will transition into PlaybackState.stopping state and then into PlaybackState.ended once the playback stops.

    Declaration

    Swift

    func stop()

  • Starts loading the content. The player will transition to PlaybackState.seeking. The player can either reach the new position in its buffer and will transition back to PlaybackState.play or PlaybackState.pausing depending on where it came from or it will first transition into PlaybackState.buffering if the requested position is not found in the current buffer.

    Declaration

    Swift

    func seek(_ time: CMTime)

    Parameters

    time

    Seeking position.

  • A collection of time ranges that the player can seek to. The ranges provided might be discontinous.

    Declaration

  • Return true for live streams, false otherwise.

    Declaration

    Swift

  • Video gravity determines how the video content is scaled or stretched within the player bounds.

    Remark

    Default value is AVLayerVideoGravityResizeAspect.

    The player layer supports the following video gravity values:

    • AVLayerVideoGravityResizeAspect: Player should preserve the video’s aspect ratio and fit the video within the bounds.
    • AVLayerVideoGravityResizeAspectFill: Player should preserve the video’s aspect ratio and fill the bounds.
    • AVLayerVideoGravityResize: Video should be stretched to fill the bounds.

    Declaration

    Swift

    var videoGravity: AVLayerVideoGravity { get set }

  • Returns underlining AVPLayer.

    Remark

    Works only with PlayerEngine.apple.
