Unable to access user selected file via NSOpenPanel in FFMPEG process in macOS app
12 décembre 2019, par RaptorI am new to macOS development via SwiftUI. I’m trying to run a FFMPEG process after I selected a MP4 file via
NSOpenPanel. However, theFFMPEGresponded with :file :///Users/MyUsername/Documents/Video.mp4 : No such file or directory
Here is my simple codes :
import SwiftUI
struct ContentView: View {
@State var selectedURL: URL?
var body: some View {
VStack {
if selectedURL != nil {
Text("Selected: \(selectedURL!.absoluteString)")
} else {
Text("Nothing selected")
}
Button(action: {
let panel = NSOpenPanel()
panel.allowedFileTypes = ["mp4"]
panel.canChooseDirectories = false
panel.canCreateDirectories = false
panel.allowsMultipleSelection = false
let result = panel.runModal()
if result == .OK {
self.selectedURL = panel.url
let savePath = self.getDownloadDirectory().appendingPathComponent("video.webm")
self.convertVideo(inputFilePath: self.selectedURL!.absoluteString, outputFilePath: savePath.absoluteString, callback: {(s) in
// omit the callback at this moment
})
}
}) {
Text("Select File")
}
}
.frame(width: 640, height: 480)
}
func getDownloadDirectory() -> URL {
let paths = FileManager.default.urls(for: .downloadsDirectory, in: .userDomainMask)
return paths[0]
}
func convertVideo(inputFilePath: String, outputFilePath: String,
callback: @escaping (Bool) -> Void) -> (Process, DispatchWorkItem)? {
guard let launchPath = Bundle.main.path(forResource: "ffmpeg", ofType: "") else {
return nil
}
let process = Process()
let task = DispatchWorkItem {
process.launchPath = launchPath
process.arguments = [
"-y",
"-i", inputFilePath,
"-vcodec", "vp8",
"-acodec", "libvorbis",
"-pix_fmt", "yuva420p",
"-metadata:s:v:0",
"alpha_mode=\"1\"",
"-auto-alt-ref", "0",
outputFilePath
]
process.standardInput = FileHandle.nullDevice
process.launch()
process.terminationHandler = { process in
callback(process.terminationStatus == 0)
}
}
DispatchQueue.global(qos: .userInitiated).async(execute: task)
return (process, task)
}
}What did I miss to allow FFMPEG process to access my selected file ? Thanks !

});Issue is that the program needs to be restarted every X minutes so that the list of media will update on it’s own. However, upon a restart, ffmpeg goes crazy and starts to spam a batch window under it’s name repeatedly over and over again without stopping. The only way out of it is to restart my computer.
I’ve tried to use PM2, Forever, Supervisor. Nodemon afaik won’t auto restart.
