我创建了一个简单的 AVPlayer。(如果我没有正确创建它,请帮我修复它...)我想用 swift ui 在我的 VStack 中显示它,但我有点卡住了...
要是库里至少有AVPlayer View组件就好了,但是我在库里没找到……
这是我的代码ContentView.swift:

// MARK: variables
var hauteurMenuBar = NSApplication.shared.mainMenu?.menuBarHeight
var urlVideo = URL(string: "/Users/francisdolbec/Movies/Se?ries Te?le?/Rick et Morty/Rick.and.Morty.S01E01.VFQ.HDTV.1080p.x264-Kamek.mp4")
let player = AVPlayer(url: urlVideo!)
struct ContentView : View {
var body: some View {
VStack {
Text("Hello World")
.frame(maxWidth: .infinity, maxHeight: .infinity)
Text("PATATE!")
//player.play()
}
.frame(minWidth: 1024, idealWidth: 1440, maxWidth: .infinity, minHeight: (640-hauteurMenuBar!), idealHeight: (900-hauteurMenuBar!), maxHeight: .infinity)
}
}
#if DEBUG
struct ContentView_Previews : PreviewProvider {
static var previews: some View {
ContentView()
}
}
#endif

顺便说一句,如果有一个教程展示如何使用 swift ui 制作视频播放器,我将非常感激!
编辑 我忘了说我正在开发一个macOS应用程序。

当然,这是Chris Mash 在 Medium上的教程。
基本上,您将 an 嵌入AVPlayerLayer到符合 的结构中UIViewRepresentable,您将对UIView要与 SwiftUI 一起使用的任何组件执行此操作。
struct PlayerView: UIViewRepresentable {
func updateUIView(_ uiView: UIView, context: UIViewRepresentableContext<PlayerView>) {
}
func makeUIView(context: Context) -> UIView {
return PlayerUIView(frame: .zero)
}
}

实现的“肉”在PlayerUIView类中完成:
class PlayerUIView: UIView {
private let playerLayer = AVPlayerLayer()
override init(frame: CGRect) {
super.init(frame: frame)
let url = URL(string: "https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8")!
let player = AVPlayer(url: url)
player.play()
playerLayer.player = player
layer.addSublayer(playerLayer)
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
override func layoutSubviews() {
super.layoutSubviews()
playerLayer.frame = bounds
}
}

然后你像这样使用它:
var body: some View {
PlayerView()
}

感谢 Bogdan 的快速回答和对教程的喜欢!
这是转换为 NSView 的代码,因此它可以适用于 macOS 应用程序...
这是结构PlayerView:
struct PlayerView: NSViewRepresentable {
func updateNSView(_ nsView: NSView, context: NSViewRepresentableContext<PlayerView>) {
}
func makeNSView(context: Context) -> NSView {
return PlayerNSView(frame: .zero)
}
}

这是课程,就像博格丹所说的“肉”:
class PlayerNSView: NSView{
private let playerLayer = AVPlayerLayer()
override init(frame:CGRect){
super.init(frame: frame)
let urlVideo = URL(string: "https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8")!
let player = AVPlayer(url: urlVideo)
player.play()
playerLayer.player = player
if layer == nil{
layer = CALayer()
}
layer?.addSublayer(playerLayer)
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
override func layout() {
super.layout()
playerLayer.frame = bounds
}
}

最后你可以使用PlayerView()添加AVPlayer到struct ContentView.
