title: Uploading video using URL swift Alamofire
body: <p>I need to upload a video to server using alamofire. The user selects the video and I get URL in didFinishPickingMediaWithInfo successfully as follows:</p>
  
  <pre><code>func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
          picker.dismiss(animated: true, completion: nil)
          if let pickedVideo = info[UIImagePickerControllerMediaURL] as? URL {
              print(pickedVideo)
          }
      }
  </code></pre>
  
  <p>And then I upload the video using the following code:</p>
  
  <pre><code>Alamofire.upload( multipartFormData: { multipartFormData in
              multipartFormData.append(videoUrl, withName: "video", fileName: "video.mp4", mimeType: "video/mp4")
  
          }, to: url, encodingCompletion: { encodingResult in
              switch encodingResult {
              case .success(let upload, _, _):
                  upload.responseJSON { response in
                      if let JSON = response.result.value as? NSDictionary {
                          completion(true)
                      } else {
                          completion(false)
                          print(response)
                      }
                  }
              case .failure(let encodingError):
                  print(encodingError)
                  completion(false)
              }
          })
  </code></pre>
  
  <p>It enters in the failure block, and the following error displays:</p>
