[TheFe91]

Version

v1.1.1

Which operating systems have you used?

• [X] Android
• [ ] iOS

Environment that reproduces the issue

• Samsung Galaxy A52 (SM-A525F/DS)
• Android 13 with One UI 5.1

Is it reproducible in the example application?

No

RTMP Server

MUX

Reproduction steps

• Enter stream screen
• Controller is initalized in this way:

  
  apiVideoLiveStreamController = ApiVideoLiveStreamController(
    initialAudioConfig: AudioConfig(bitrate: 128000),
    initialVideoConfig: VideoConfig(
      fps: 30,
      bitrate: 3000000,
      resolution: Resolution.RESOLUTION_720,
    ),
    initialCameraPosition:
        GetPlatform.isAndroid ? CameraPosition.back : CameraPosition.front,
    onConnectionSuccess: () {
      debugPrint('Connected');
      isStreaming(true);
    },
    onDisconnection: () {
      debugPrint('Disconnected');
      isStreaming(false);
    },
    onError: (error) {
      Sentry.captureException(error);
      if (kDebugMode) {
        _logger.e(error.toString());
      }
    },
    onConnectionFailed: (reason) {
      debugPrint('Failed: $reason');
    },
  );

await apiVideoLiveStreamController.initialize();

await apiVideoLiveStreamController.startStreaming( streamKey: sc.currentStreamKey.value!, url: Strings.muxBaseRtmpUrl, );

* Stream starts normally
* wait 5 to 10 seconds
* Stream goes on error

### Expected result

StreamPack streams over given RTMP

### Actual result

`PlatformException: io.github.thibaultbee.streampack.error.StreamPackError`

### Additional context

Flutter 3.10.3 • channel stable • https://github.com/flutter/flutter.git Framework • revision f92f44110e (5 days ago) • 2023-06-01 18:17:33 -0500 Engine • revision 2a3401c9bb Tools • Dart 3.0.3 • DevTools 2.23.1

No error is raised in the example application.

Just tried with Android emulator (Pixel 6A API 33) and it works... I really don't understand, I'm astonished

I tried from my app to stream over my youtube channel and it worked. So it must be something related to my app + mux...From the example app + mux however it worked as I wrote above. Hope these details help!

I think I solved the problem. I was missing the scaffoldKey from the main Scaffold, so it probably had a re-render that caused an error within StreamPack.
