Local Streaming audio is not working in the ios device

[srinivas1100]

Which API doesn't behave as documented, and how does it misbehave?
I'm using the just_audio package to generate audio from OpenAI and play it. I'm utilizing the http StreamedResponse to generate the audio. After receiving a successful response, I open the HttpServer and bind the response to this server. The code details are provided below. While this setup works fine on Android, it's not functioning properly on iOS.

Minimal reproduction project
Provide a link here using one of two options:

1. Fork this repository and add the api key https://github.com/srinivas1100/bug-report-audio-package.git

  class OpenAiApi {
  final String _baseUrl = 'https://api.openai.com/v1/audio/speech';
  final String _apiKey;
  AudioPlayer audioPlayer = AudioPlayer();
  OpenAiApi(this._apiKey);
  Future<void> getSpeech(String model, String input, String voice) async {
    log("GET SPEECH IS CALLED");
    final client = http.Client();
    final request = http.Request('POST', Uri.parse(_baseUrl))
      ..headers['Authorization'] = 'Bearer $_apiKey'
      ..headers['Content-Type'] = 'application/json'
      ..body = jsonEncode(<String, String>{
        'model': model,
        'input': input,
        'voice': voice,
      });

    StreamedResponse streamedResponse = await client.send(request);

    // streamedResponse.stream.listen((data) {
    //   log("STREAM DATA : $data");
    // });
    log("STREAM REQUEST IS SENT");

    HttpServer server =
        await HttpServer.bind(InternetAddress.loopbackIPv4, 8080, shared: true);

    try {
      server.listen(
        (HttpRequest serverRequest) async =>
            await streamedResponse.stream.pipe(serverRequest.response),
      );
    } catch (e) {
      log(e.toString());
    }

    log("PORT IS LISTENING ${server.port}");

    // log("STREAM LENGTH : ${streamedResponse.contentLength}");

    await audioPlayer.setUrl('http://localhost:${server.port}');

    // await audioPlayer.load();

    await audioPlayer.play();

    log("AUDIO PLAYER LENGTH : ${audioPlayer.durationStream}");

    log("AUDIO IS PLAYING");
  }
}

To Reproduce (i.e. user steps, not code)
Steps to reproduce the behavior:

1. Fork the code in this url https://github.com/srinivas1100/bug-report-audio-package.git
2. launch any ios device
3. run any real ios device or simulator
4. click the button it will get the error

Error messages

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: (-11850) Operation Stopped

<asynchronous suspension>
#1      AudioPlayer._setPlatformActive.setPlatform (package:just_audio/just_audio.dart:1465:28)
<asynchronous suspension>

Expected behavior
Once the API returns the streaming response, I bind it to a local server. Then, I use the URL of that local server with the audio player, which automatically plays the audio.

Hi! were you able to get over this problem? im facing the same issue

[maeda-takuyaa]

I have the same problem as you, is there a way to fix this error? Thanks

[willsmanley]

I'm experiencing the same issue. I also created a minimal reproducible example here: https://github.com/willsmanley/audio-test

This example connects to a websocket server, receives Uint8List bytes, but cant play audio from the stream and eventually results in:
flutter: Error in playing stream: (-11800) The operation could not be completed
flutter: Error in playing stream: MissingPluginException(No implementation found for method load on channel com.ryanheise.just_audio.methods.91d20774-96b0-4621-9a66-8aebce1776d5)

I have the correct ios permissions and flutter clean.

Thank you in advance for any support!

I have the same error like, my audiobytes. from websocket too, and define a new class extend StreamAudioSource,
but it print Source error Exception;
