Why is the file type 'video/mp4' and not 'audio/mpeg'?

[RohithKilaparthi]

We are trying to record a voice from android and post it to Firebase Storage. When we are trying to play the voice in android, it gets played well, but when it is on Firebase, it fails to play. When I investigated, I saw that the file type is 'video/mp4' and not 'audio/mpeg'.

Can you look into the issue and help us a way through?

This is the code snippet we are using:

 void startRecorder(formDetail) async {
    try {
      DateTime timeStamp = DateTime.now();
      String fileName = Uuid().v1() + "-" + timeStamp.toString();
      fileName = fileName + (Platform.isIOS ? '.m4a' : '.mp3');
      setResponseField(formDetail, fileName);
      String path = await flutterSound.startRecorder(fileName);
      _recorderSubscription =
          flutterSound.onRecorderStateChanged.listen((e) {});
      _dbPeakSubscription =
          flutterSound.onRecorderDbPeakChanged.listen((value) {
        print("got update -> $value");
        setState(() {
          // this._dbLevel = value;
        });
      });

      this.setState(() {
        this._isRecording = true;
        setResponseField(formDetail, path);
      });
    } catch (err) {
      print('startRecorder error: $err');
    }
  }

  void stopRecorder(formDetail) async {
    try {
      String result = await flutterSound.stopRecorder();
      String path = responses[formDetail.field];
      var obj = {
        "siteId": site.siteId.toString(),
        "formId": form.formId.toString(),
        "field": formDetail.field.toString()
      };
      print(path);
      if (_recorderSubscription != null) {
        _recorderSubscription.cancel();
        _recorderSubscription = null;
      }
      if (_dbPeakSubscription != null) {
        _dbPeakSubscription.cancel();
        _dbPeakSubscription = null;
      }

      this.setState(() {
        this._isRecording = false;
      });
      File audioFile = File(path);
      List paths = path.split("/");
      uploadFile(audioFile, paths[paths.length - 1], obj);
      setResponseField(formDetail, paths[paths.length - 1]);
    } catch (err) {
      print('stopRecorder error: $err');
    }
  }

@hyochan can you please check and provide an update?

I think it is related to some other issues such as this. Try to use ffmpeg making cloud function via firebase.
