Internal class used by VideoStream to manage playback state when played from a VideoStreamPlayer.
class VideoStreamPlaybackThis class is intended to be overridden by video decoder extensions with custom implementations of VideoStream.
import SwiftGodotFramework to write Godot Game Extensions using the Swift Programming Language.
class VideoStreamBase resource for video streams.
class VideoStreamPlayerA control used for video playback.
class ResourceBase class for serializable objects.
protocol CustomStringConvertibleA type with a customized textual representation.
protocol EquatableA type that can be compared for value equality.
protocol Hashable : EquatableA type that can be hashed into a Hasher to produce an integer hash value.
protocol Identifiable<ID>A class of types whose instances hold the value of an entity with stable identity.
protocol VariantRepresentable : VariantStorableTypes that conform to VariantRepresentable can be stored directly in Variant with no conversion. These include all of the Variant types from Godot (for example GString, Rect, Plane), Godot objects (those that subclass SwiftGodot.Object) as well as the built-in Swift types UInt8, Int64 and Double.
protocol VariantStorableTypes that conform to VariantStorable can be stored in a Variant and can be extracted back out of a Variant.
override class var godotClassName: StringName { get }func _getChannels() -> Int32 Returns the number of audio channels.
func _getLength() -> Double Returns the video duration in seconds, if known, or 0 if unknown.
func _getMixRate() -> Int32 Returns the audio sample rate used for mixing.
func _getPlaybackPosition() -> Double Return the current playback timestamp. Called in response to the streamPosition getter.
func _getTexture() -> Texture2D? Allocates a Texture2D in which decoded video frames will be drawn.
func _isPaused() -> Bool Returns the paused status, as set by _setPaused(_:).
func _isPlaying() -> Bool Returns the playback state, as determined by calls to _play and _stop.
func _play() Called in response to autoplay or play. Note that manual playback may also invoke _stop multiple times before this method is called. _isPlaying should return true once playing.
func _seek(time: Double) Seeks to time seconds. Called in response to the streamPosition setter.
func _setAudioTrack(idx: Int32) Select the audio track idx. Called when playback starts, and in response to the audioTrack setter.
func _setPaused(_ paused: Bool) Set the paused status of video playback. _isPaused must return paused. Called in response to the paused setter.
func _stop() Stops playback. May be called multiple times before _play, or in response to stop. _isPlaying should return false once stopped.
func _update(delta: Double) Ticks video playback for delta seconds. Called every frame as long as _isPaused and _isPlaying return true.
final func mixAudio(numFrames: Int32, buffer: PackedFloat32Array = PackedFloat32Array(), offset: Int32 = 0) -> Int32 Render numFrames audio frames (of _getChannels floats each) from buffer, starting from index offset in the array. Returns the number of audio frames rendered, or -1 on error.
