same issue in android

[Larpoux]

Check :

• What is the file that you try to play
• What is its extension
• What is the codec that you specified to startPlayer()

[bhargav6744]

@Larpoux what should be a codec for video picked from iOS device ?

[alperenbaskaya58]

Check :

• What is the file that you try to play
• What is its extension
• What is the codec that you specified to startPlayer()

i faced issue on real ios device only. extension: .aac codec: Codec.aacADTS file: /var/mobile/Containers/Data/Application/8E613239-E966-4244-B5AD-832263CBB5E6/Library/Caches/12323123.aac

[Larpoux]

I am not sure that /var/mobile/Containers/Data/Application/8E613239-E966-4244-B5AD-832263CBB5E6/Library/Caches/12323123.aac is in your sandbox

I am not sure that /var/mobile/Containers/Data/Application/8E613239-E966-4244-B5AD-832263CBB5E6/Library/Caches/12323123.aac is in your sandbox

what to do then? Any reccomendations?

[Larpoux]

Most of the time you must call the flutter plugin 'path_provider' to get a correct path where you can store or read your files.

[alperenbaskaya58]

Most of the time you must call the flutter plugin 'path_provider' to get a correct path where you can store or read your files.

tempDir = await getTemporaryDirectory();

this is the directory of the file where I uses pathprovider

[Larpoux]

That's correct.

But 'var/mobile/Containers/Data/Application/8E613239-E966-4244-B5AD-832263CBB5E6/Library/Caches/12323123.aac' seems to be a path for an ios emulator, not a correct path for a real device

[alperenbaskaya58]

I am using real device and nothing work for playing. This path is from real device var/mobile/Containers/Data/Application/8E613239-E966-4244-B5AD-832263CBB5E6/Library/Caches/12323123.aac

 tempDir = await getTemporaryDirectory();
    log(tempDir!.path.toString());
    PermissionStatus status;
    try {
      status = await Permission.microphone.request();
    } catch (e) {
      throw e;
    }
    log(tempDir.path.toString());

    if (status != PermissionStatus.granted)
      throw RecordingPermissionException("You must give acces to mic");
    pathToRecord =
        "${tempDir.path}/${DateTime.now().millisecondsSinceEpoch.toString()}.aac";

    await flutterSoundRecorder.startRecorder(
      toFile: "$pathToRecord",
      codec: Codec.aacADTS,
    );

playing;
  play(path) async {
    await flutterSoundPlayer.startPlayer(
        fromURI: path,

        //fromDataBuffer: bytes,
        codec: Codec.aacADTS);
    update();
  }

[Larpoux]

Your code seems correct. I don't see. Is your player correctly open?

[alperenbaskaya58]

Yes, it works on android debug, android release and ios debug. It doesnt work only release mode on iOS.

[Larpoux]

Is there any reason you use FS 8.x and not 9.2? Do you depend on another Flutter audio plugin, than Flutter Sound?

[alperenbaskaya58]

i am using fs 9.1.8 to 9.2.2 not 8

[minh-dai]

i have the same, I copy your code in the example project (SimpleRecorder), and try to record, then play audio, but it has an error (android working), i don't change anything, please tell me how i can fix this error @Larpoux thank you. flutter_sound: ^9.2.13 ios: 15.4.1

[JettChen12]

same issue, anyone found a solution?

[hbalxzdl]

Execute openPlayer first and then startPlayer, and the issue will be resolved

play() async {
    await flutterSoundPlayer.openPlayer()
    await flutterSoundPlayer.startPlayer()
}
