When calling constructor of Player: https://github.com/bdlukaa/just_audio_libwinmedia/blob/21b43158e68eaa47abc9d783cc33b47e98e477ce/lib/src/just_audio_libwinmedia_real.dart#L50

startLoop: !Platform.isLinux must be add as the comment of libwinmedia suggests: https://github.com/harmonoid/libwinmedia/blob/71a7f157a0d3ed9a6394e73de7585a7c9a3525fa/flutter/lib/src/player.dart#L147

Hey. @bdlukaa

Thanks for your work! It's not an issue, but could you please provide an example project (counter with .wav sound on FAB tap, will be enough)? It may help all of us in future debugging and issue reporting. Also, it will probably add some pub points to your package. Thanks in advance!

This method blocks on(callstack): https://github.com/ryanheise/just_audio/blob/1c6598c0f3589baac4194e71b4d2885205f58ef4/just_audio/lib/just_audio.dart#L683 https://github.com/ryanheise/just_audio/blob/1c6598c0f3589baac4194e71b4d2885205f58ef4/just_audio/lib/just_audio.dart#L708 https://github.com/ryanheise/just_audio/blob/1c6598c0f3589baac4194e71b4d2885205f58ef4/just_audio/lib/just_audio.dart#L772-L773

That's because processingStateStream did not receive any state change. When player opens: https://github.com/bdlukaa/just_audio_libwinmedia/blob/21b43158e68eaa47abc9d783cc33b47e98e477ce/lib/src/just_audio_libwinmedia_real.dart#L164 It calls Player::Open internally, which sets video.src and does not fire any events: https://github.com/harmonoid/libwinmedia/blob/71a7f157a0d3ed9a6394e73de7585a7c9a3525fa/linux/player.hpp#L326-L329

For the latest version of webkit2gtk (2.36.1) ProcessingStream.listener never gets called for ProcessingState.completed event when the audio file has finished playing Also the state never gets set to ProcessingState.completed when the track has finished playing The entire scenario works perfectly fine if using older versions of webkit2gtk/libwebkit2gtk (all versions before latest gnome-41 & after gnome-36)

Error occurring piece of code: https://github.com/KRTirtho/spotube/blob/3b7f7785b66e63dfe56b07c49d009441ad56219b/lib/provider/Playback.dart#L113-L130

Tested on Operating Systems/Platforms:

• Fedora 35 (Gnome-42)
• Endeavour OS (Gnome-42)
• Flatpak-Flathub with org.gnome.SDK@41

Minimal reproduction project example repository

To Reproduce

1. Navigate to just-audio/example
2. Modify the directory variable with the absolute path of the example folder
3. Run the application
4. The "loading" ring should never stop spinning

Expected behavior Playback should occur almost immediately as is with the commented code below.

Desktop

• Windows 10 Version 10.0.19044 Build 19044

Flutter SDK version

• channel stable
• version 2.10.3

Thanks very much for providing this package for desktop platforms.

I'm trying to use just audio on linux, but it does not work well.

my pubspec.yaml

flutter:
  just_audio: ^0.9.20
  just_audio_libwinmedia: ^0.0.4

...

assets:
  - audios/passing.wav

my versions

$ flutter doctor

And my test code

      onPressed: () async {
        ...
        else{
          final player = AudioPlayer();
          await player.setAsset('audios/passing.wav');
          await player.play();
          await player.stop();
          await player.dispose();
        }
      }

And Result on Pressed

"Windows HLS supported"

Describe your suggestion

According to https://github.com/ryanheise/just_audio/issues/103#issuecomment-922405803 and my tests, HLS does not work on Windows, it just keeps buffering and will not play.

Tested with https://devstreaming-cdn.apple.com/videos/streaming/examples/img_bipbop_adv_example_fmp4/master.m3u8, works with Android.

audioPlayer?.setAudioSource(
      HlsAudioSource(
        Uri.parse(
            "https://devstreaming-cdn.apple.com/videos/streaming/examples/img_bipbop_adv_example_fmp4/master.m3u8"),
      ),

Currently just_audio_libwinmedia returns a duration of zero when loading any media. It seems libwinmedia has the ability to listen to duration changes, so maybe this could be used to listen for, and return, the duration in just_audio_libwinmedia (not sure if there might be a better way...)
