在SwiftUI中使用FFmpeg可以实现对音视频的处理和编辑。下面是一个使用FFmpeg的示例代码:
```swift
import SwiftUI
import AVKit
struct ContentView: View {
var body: some View {
VStack {
Button(action: {
// 使用FFmpeg处理音视频
let ffmpegPath = Bundle.main.path(forResource: "ffmpeg", ofType: nil)
let inputPath = Bundle.main.path(forResource: "input", ofType: "mp4")
let outputPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first! + "/output.mp4"
let command = "\(ffmpegPath ?? "") -i \(inputPath ?? "") -vf \"scale=640:480\" \(outputPath)"
let task = Process()
task.launchPath = "/bin/bash"
task.arguments = ["-c", command]
task.launch()
task.waitUntilExit()
// 播放处理后的视频
let player = AVPlayer(url: URL(fileURLWithPath: outputPath))
let playerViewController = AVPlayerViewController()
playerViewController.player = player
UIApplication.shared.windows.first?.rootViewController?.present(playerViewController, animated: true) {
player.play()
}
}) {
Text("处理视频")
.padding()
.background(Color.blue)
.foregroundColor(.white)
.cornerRadius(10)
}
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
```
这段代码使用FFmpeg将输入视频文件进行缩放处理,并将处理后的视频保存到输出路径。然后使用AVPlayerViewController播放处理后的视频。
请注意,上述代码中需要将FFmpeg可执行文件和输入视频文件添加到项目中,并在代码中正确指定它们的路径。
