• Debugging my App ?

Here is my question:

I'm trying to play play() a track from a remote url using Track.fromURL(). When I feed this track to my SoundPlayer().play(track), I'm getting an error due to AudioPlayer initialisation timeout from the SoundPlayer's _initializeAndRun method. I'm not sure why it's failing. It appears to be happening on both an iOS simulator and an Android device. If I don't provide a coded or provide a Codec.fromExtension, I get a uri error: The uri's extension does not match any of the supported extensions. You must pass in a codec.. I'm trying to play files from Firebase Storage, so the links don't have a file extension in the url.

I am using the Sounds package primarily for the recorder. I am not using the SoundPlayer (since it requires the file to be completely downloaded before playing, which isn't viable for a podcast app when the download delay could take 10+minutes), but am instead using a different audio player (audioplayers) and audio_service for the notification state. This appears to all be working fine, except for the media buttons in the notification state don't work because both audio_service (correctly) and sounds (incorrectly since I'm not using the player or shade player) are registering to the same media buttons which is causing errors.

Does anyone know how to prevent sounds from registering the background audio service/notification area so I can handle this with the audio_service package?

Describe the bug I'm unable to get my app to build for iOS (seems to work for Android) due to the above error when building. I am trying to switch over from using Flutter Sound since I've updated my flutter version. I'm excited about this fork and having a cleaner API for the sound system! Would love to help contribute any way I can (I'll admit, I know very little about iOS development, however).

Describe the bug I am using this package for a chat messages, I also want to play a sound when the recording starts. But when I play the recording, the soundrecorder stops recording.

To Reproduce

1. Start recording
2. Play small asset audio
3. Record for a longer time that the player audio
4. Stop recording
5. see recorded length

Expected behavior Recorder should still record after audio file is played

Additional context**

This is my recorder

class VoiceRecorder extends ChangeNotifier {
  SoundRecorder _mRecorder = SoundRecorder();

  String _mPath;

  File get audioFile => File(_mPath);

  VoiceRecorder() {
    _mPath = Track.tempFile(WellKnownMediaFormats.adtsAac);
    print("open recorder");

    // openTheRecorder();
  }
  var duration = 0;
  var isRecording = false;

  Timer timer;

  startRecording() async {
    // assert(_mPlayer.isStopped);

    final track =
        Track.fromFile(_mPath, mediaFormat: WellKnownMediaFormats.adtsAac);
    resetTimer();
    timer = Timer.periodic(Duration(seconds: 1), (timer) {
      duration += 1;
      notifyListeners();
    });

    _mRecorder.record(track);
    // MyPlayer.SoundPlayer.playSound(MyPlayer.SoundEffect.Start);
    playSoundEffect(SoundEffect.Start);
    isRecording = true;
    notifyListeners();
  }

  String get recordedSeconds {
    final minutes = duration / 60 % 60;
    final seconds = duration % 60;
    return "${minutes.toInt()}:${seconds.toString().padLeft(2, "0")}";
  }

  Future<bool> stopRecorder(bool save) async {
    var shouldSave = false;

    try {
      await _mRecorder.stop();
      if (save && duration > 1) {
        print("ending recording");
        playSoundEffect(SoundEffect.End);
        shouldSave = true;
      } else {
        print("canceling recording");
        playSoundEffect(SoundEffect.Error);
      }
    } on Object catch (err) {
      print('stopRecorder error: $err');
      playSoundEffect(SoundEffect.Error);
    }
    timer?.cancel();
    isRecording = false;
    notifyListeners();
    print("stopRecorder save $save duration: $duration");
    return shouldSave;
  }

  resetTimer() {
    timer?.cancel();
    duration = 0;
  }

  var player = SoundPlayer.noUI();
  playSoundEffect(SoundEffect effect) {
    // return; // when uncommented, recorder works fine
    String soundStr;
    switch (effect) {
      case SoundEffect.Start:
        soundStr = "assets/sounds/record_start.wav";
        break;
      case SoundEffect.End:
        soundStr = "assets/sounds/record_finished.wav";
        break;
      case SoundEffect.Error:
        soundStr = "assets/sounds/record_error.wav";
        break;
    }
    if (soundStr != null) {
      var track = Track.fromAsset(soundStr);
      player.play(track);
    }
  }

  @override
  dispose() {
    _mRecorder?.release();
    player.release();
    _mRecorder = null;
    if (_mPath != null) {
      var outputFile = File(_mPath);
      if (outputFile.existsSync()) {
        outputFile.delete();
      }
    }
    super.dispose();
  }
}

I need Help for :

• Using the API ?

Here is my question : Hi, I'm a new flutter dev so this might be trivially answered...

I'm trying to use the quickplay class to play from a .wav file. I know the file is legit...and the app works otherwise, so here is the relevant piece of code:

    var test_track = Track.fromAsset('assets/sound/track.wav');
    QuickPlay.fromTrack(test_track);

I just call that when a button is pressed (the callback registered to onpressed has these 2 lines in it).

my dir structure for assets:

and the relevant part of my pubspec...

flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  assets:
    - assets/sounds/track.wav

And the stacktrace:

flutter pub deps :

just firebase_messaging, here is a repo of a project replicating the issue https://github.com/markusaksli-nc/sounds-messaging-issue

Screenshots

Describe the bug I submitted this bug on firebase a while ago but I think it is also worth it to mention it here. Theres a firebase_messaging function to receive background notifications and when the function is registered, the communication from Android to Dart stops working in this plugin. I honestly don't know which package to blame, but I think a lot of us might use this combination of plugins and the bug took me hours to detect that could save time to others.

The issue is well described in the original firebase issue. so I'll keep it short here

To Reproduce Steps to reproduce the behavior:

1. Register onBackgroundMessage function from firebase_messaging
2. Play audio file
3. See error

Expected behavior A clear and concise description of what you expected to happen. The progress indicator would not move, it seems that android is indeed sending updates of the progress but dart is not receiving them. After commenting the registration of the background message, the progress indicators works as expected.

Additional context**

I did some research on their plugin and it seems that they are creating a new FlutterEngine on that function, maybe this plugin (or all plugins) are confusing it with the original FlutterEngine?

Describe the bug For every Slider widget update, i seek the player. It happened to throw this error with no reference to my code.

Hey, thanks for the great library, I'm really pleased with it! I would like to ask for help related to these questions:

I'm streaming from my server raw Opus frames, without OGG or CAF container. Since iOS uses CAF instead of the standard OGG container, I'm trying to play the raw frames, so maybe somehow both of them can play my stream. But if necessary I can encapsulate it in a container. Is it possible to play raw Opus? Or somehow play CAF/Opus on Android maybe?

My app receives audio data periodically through the websocket. I would like to redirect this audio stream to the player so it can play it continously. Is it somehow possible?

Thank you very much in advance!

Is your feature request related to a problem? Please describe. My use case as an example is playing a playlist, with each "track" consisting of several files with blank space between each file and the user can pause the "playlist" at any point (when the files are actively playing or when the files have naturally stopped and they are in the blank/delay between sound files playing). The shade can't accurately show that the user paused the playlist unless the user happened to hit pause in the midst of an actual sound playing. Everything seems to work really well as far as functionality of the player/events propagating from the shade/etc. it's just the visual state of the shade needs to be able to be updated to accurately show what the user would expect in a scenario like this.

Describe the solution you'd like Ability to change state of play/pause/stopped OS shade's UI separately from the actual state of sound files.

Describe alternatives you've considered The only alternative I've found is triggering a small/blank sound to play if no sound is playing when they hit pause, so it triggers "play" and then immediately triggers "pause" which makes the shade show the correct state.

I've been looking into the issues around #344 (re-architect codec support) and have come to the realisation that we have a number of problems with how we are using the Codec class.

Reference material: https://developer.android.com/guide/topics/media/media-formats

The Codec class has morphed into an object that attempts to describe both the Codec and the media container.

This appears problematic as the Codec is not able to fully describe a media's format and the class name is misleading as it describes more than just a Codec.

I'm proposing that we create a new class MediaFormat.

class MediaFormat
{
 Codec codec;
 MediaContainer container;
int sampleRate = 16000,
int numChannels = 1,
int bitRate = 16000,
Quality quality = Quality.low,
}

Note: I'm uncertain whether quality belongs here, its taken from the SoundRecorder.record method.

The MediaFormat would replace Codec in the public api so when creating a Track you would now use something like:

var format = MediaFormat.default;
var track = Track.fromPath(path, format);

var format = MediaFormat(Codecs.byName('mpeg'), MediaContainer.byName('mpeg'));
format.sampleRate = 1000;
format.numChannels = 2;

track  = Track.fromBuffer(buffer, format);

I believe this method has a number of advantages:

1. we are now accurately describing the users requested media format.
2. when doing codec conversions we would use the MediaFormat rather than just the Codec. This allows conversions to fully describe the desired target format. (e.g. stereo to mono, down sampling etc).
3. We change the SoundRecorder.record method to take a MediaFormat which makes the api consistent.
4. we future proof the api as MediaFormat accurately describes the format which means we are less likely to have to change the api. With the current implementation this is highly likely as the current Codec is a enum which means we can't add additional properties.

The down side is that it probably makes our life harder as we need to deal with users passing formats that are not supported or inconsistent. Inconsistency is perhaps a problem with the SoundPlayer as it would essentially ignore the properties. The flip side is that I can't think of why this would be an actual problem. We also make the users life slightly harder as it takes more lines of code to describe a MediaFormat than a Codec. Having a number of default MediaFormats would mitigate this problem.

Thoughts?

Please provide null safety support. Also few months back you told you are releasing version 1 but on pub.dev it's still not version 1. It's a good project. Please update soon. Thanks

Sounds is a fork of the Flutter Sound project.

In Flutter Sound we have

Flutter Sound requires an iOS 10.0 SDK (or later) Flutter Sound requires an Android API level 21 (or later)

What about sounds ?

When handing local system paths, a special constructor must be called on URL. See the official documentation.

For example, without this fix /Users/some-user/Library/Developer/CoreSimulator/Devices/828006A2-398A-40E6-B8C4-10D6974A84EA/data/Containers/Data/Application/005825E6-2EC9-45BD-9F9F-54EE3D3033D8/Library/Application Support/audio/some-audio-file

would result in nil being handed as a URL to AVAudioPlayer.

Unfortunately the project did not compile, so I applied some quick fixes as a second commit to this PR to make the project work. The actual fix can be found in this commit

I've opened this issue to track work on converting the iOS code (and eventually the java code) to FFI calls.

The work is being down in:

https://github.com/bsutton/sounds/tree/sounds_federated

The problem we are having right now is that we need 3 languages (dart, objective-c, java) to maintain Sounds. As we move to support more platforms this will only get worse.

As such we are looking to move to FFI (foreign function interface) to do direct calls from Dart into the required native calls. This will result in only a single language being required (dart) to support Sounds.

Our fall back position is to use 'C' as a bridging language to the platform native calls. The 'C' bridge will be a very small wrapper for each native call. The reason for this is that we are still uncertain if we can achieve FFI calls directly to iOS native libraries.

What is the current state of this development?

The ffi work is proving fairly difficult but we are making (slow) progress. We would certainly appreciate any help.

Were we are right now:

We have done a conversion of the objective-c code to dart. We did this by putting the objective-c code throught swiftify to create swift code. We then manually modified the swift code (line by line) to change it to dart code. This process went fairly smoothly but there are still a few spots where we are not certain if we converted the code correctly but we think its mostly close.

We are now looking at how we do the native calls to IOS libraries.

We are using the dart-native package to do the heavy lifting as it provides a reasonable wrapper for calls into ios.

The next step is to provide a dart wrapper library for the set of ios calls we need to make.

We have done some of this work.

The process we have been using:

Try using the dart-native 'generator' to create dart wrappers for the required ios library. This has been partially successful but the generator often fails as it is still unable to parse some of the objective-c syntax.

When this occurs we try to create a 'cut-down' version of the ios header files that only contain the required entry points. This often gives us a much better chance of doing the conversion.

As of now we think we have managed to create dart wrappers for each of the ios calls used by Sounds. We are still uncertain if these dart wrappers are correct.

The next step is to get each of these functions to dynamically load. This requires us to find the ios library for each of these entry points.

We raised an question on stack overflow to get some guidance on this.

https://stackoverflow.com/questions/65083514/ios-dylib-entry-points

The summary answer is: In that case, I suggest searching through the folder /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk. The .tbd files in there contain library paths as well as a list of exported symbols. – Siguza Dec 3 '20 at 23:14

Actions:

1. finding the list of exports to that we need to call. You can see the calls we are making in: https://github.com/bsutton/sounds/tree/sounds_federated/sounds/lib/src/ios

2. Make a decision on the final structure of the code based. We are trying to move to a federated model that still allows uses to use pigeon if that is the appropriate solution and given that in the short term we will be using pigeon with the java code.

This stack overflow article has some useful references: https://stackoverflow.com/questions/64037971/using-dart-pigeon-in-a-federated-model
