尝试使用Alamofire上传.mp4视频文件，但上传.mov（Swift）

Question

我正在尝试上传我从iPhone录制的.mp4文件，但是它将.mov更改为API。我在调用之前检查视频URL路径，我可以确认写入文件按预期工作。我怎么能改变它？

public func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

        print("didFinishPickingMediaWithInfo")
        if let pickedVideo:NSURL = (info[UIImagePickerControllerMediaURL] as? NSURL) {

            let videoData : Data!
            do {
                try videoData = Data(contentsOf: pickedVideo as URL)
                var paths = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)
                let documentsDirectory = paths[0]
                let tempPath = documentsDirectory.appendingFormat("/vid1.mp4")
                let url = URL(fileURLWithPath: tempPath)
                do {
                    try _ = videoData.write(to: url, options: [])
                }
                uploadVideoToAPI(tempPath)
            }
}

func uploadVideoToAPI(tempPath:String) {
       API.uploadVideo(URL(fileURLWithPath:tempPath)
}

class func uploadVideo(videoUrl:URL) {
        Alamofire.upload(
            multipartFormData: { multipartFormData in
                multipartFormData.append(videoUrl, withName: "profileVideo", fileName: "video.mp4", mimeType: "video/mp4")
        },
            to: "\(baseUrl)",method: 
            encodingCompletion: { encodingResult in
                switch encodingResult {
                case .success(let upload, _, _):
                    upload.responseJSON { response in
                        debugPrint(response)
                    }
                case .failure(let encodingError):
                    print(encodingError)
                }
        }
        )
    }
