Error decoding audio

[Vito0912]

I have built a simple app that fetches a stream from a server. Recently, I switched the video type to perform the encoding on the client-side. Since then, I have been receiving an error stating that the audio cannot be decoded ("Error decoding audio."). The error message is displayed in the middle of the screen, which is problematic.

As a temporary solution for my personal project, I would like to suppress or hide the error message. However, in its current state, the plugin is not usable for me.

The exception shown in the console is: PlatformException(, Error decoding audio., null, null)

Note that despite the error message, the audio continues to play, so no error there.

Is there a way to suppress or hide this error message? Any help would be appreciated. Thank you.

Thank you very much, can you provide the full logs and platform you are using,

And if you are enabling media_kit or not, since it will help me greatly to fix the issue

The logs will help me define the caller of throw of the exception which will help me fix it

Also I think it's coming from the media_kit error stream, so I can disable it, by exposing a flag, but I will have to wait for your logs to be 100% sure

Sorry, I forgot to include the important facts. I just forgot to copy and paste them in. Thank you very much for the fast reply. Here are the other details:

OS: Windows Targeting OS: Windows Flutter: 3.10.6 Plugin Version: 4.2.22

As I am new to using the Flutter cross-platform media player, I am not sure which one is used for Windows. However, since I cannot disable or enable it at initialization, I assume that it is the only option for Windows or not available for Windows.

I search a bit where the log message (and the PlatformException) came from, but found nothing related to meedu in the packages

[abdelaziz-mahdy]

Like I mentioned it came from media_kit will add the flag and let you know.

[Vito0912]

I found a more or less suitable solution - in short-term. When creating a MeeduPlayerController it let´s you define an errorText. If you set it to '' the error messages will be overwritten by this. Sadly this also disables the controls for the video, so not optimal too.

[abdelaziz-mahdy]

hello, in 4.2.23, you can disable the throwing of the error in media_kit since its not valid in your case just use

  initMeeduPlayer(
    throwErrors: false
  );
