Unable to get the picture at the specified time

Temporary repair method
private func getFileThumbnail(_ path: String,_ quality: NSNumber,_ position: NSNumber,_ result: FlutterResult) {
let fileName = Utility.getFileName(path)

//change
let url = Utility.getPathUrl("\(Utility.basePath())/\(fileName)_\(position).jpg")

Utility.deleteFile(path)
if let bitmap = getBitMap(path,quality,position,result) {
guard (try? bitmap.write(to: url)) != nil else {
return result(FlutterError(code: channelName,message: "getFileThumbnail error",details: "getFileThumbnail error"))
}
result(Utility.excludeFileProtocol(url.absoluteString))
}
}

Start with the Dart call to VideoCompress.getFileThumbnail and the Swift getFileThumbnail method shown in the issue. Reproduce requests at different positions and compare the returned image with the specified time; done means thumbnails are retrieved for the requested positions without relying on the temporary repair.
