just_audio_windows's Issues

There are several problems: 1. The seek bar cannot be seek. 2. There is only one channel. 3. Cannot play local file. 4. No callback after playback

1、const auto* position = std::get_if(ValueOrNull(*args, "position")); int64_t -> int

2、 const auto* pitch = std::get_if(ValueOrNull(*args, "pitch")); need set pitch = 0;

3、//Create a new picker
var filePicker = new Windows.Storage.Pickers.FileOpenPicker();

//make a collection of all video types you want to support (for testing we are adding just 3).
string[] fileTypes = new string[] {".wmv", ".mp4", ".mkv"};

//Add your fileTypes to the FileTypeFilter list of filePicker.
foreach (string fileType in fileTypes)
{
filePicker.FileTypeFilter.Add(fileType);
}

4、must add a method

Playing audio sometimes crashes - EXCEPTION CAUGHT BY SERVICES LIBRARY

When trying to play audio, it sometimes works, other times, it crashes.
In some of the cases, I'm jumping to a next track (calling _player.stop().then(... load & play next track ...)) even if the current one has not finished playing yet.

`currentIndex` is not always getting reported correctly in events

The currentIndex parameter isn't always getting set correctly on the broadcastPlaybackEvent method. I think this is because mediaPlaybackList isn't getting updated unless the playback type is concatenating, but it could be caused by something else.

Things seem to be better behaved if I make the changes:

such that mediaPlaybackList is always updated, but I don't have enough of an understanding of what everything else is doing to know what affect this will have on the rest of the plugin's operation.

WAV data of initially unknown length through StreamAudioSource is silent for prolonged periods of time before playing

Which API doesn't behave as documented, and how does it misbehave?
When an AudioPlayer plays from a StreamAudioSource that returns a response with a stream containing WAV PCM data and contentLength: null, sourceLength: null, offset: null to indicate that the overall length of the stream is not currently known, e.g. background sound that is continually generated, the audio is not played immediately. It may instead be played several minutes after the request completes, even for short amounts of data, e.g. 1 second long.

`currentIndex` is not always getting reported correctly in events

Which API doesn't behave as documented, and how does it misbehave?
AudioPlayer::broadcastPlaybackEvent doesn't set the currentIndex parameter correctly.

Minimal reproduction project
Subscribe to the playbackEventMessageStream stream on an audio player instance, and observe the state of the currentIndex parameter (when the playback type is not concatenating).

To Reproduce (i.e. user steps, not code)
Subscribe to the playbackEventMessageStream stream on an audio player instance, and observe the state of the currentIndex parameter (when the playback type is not concatenating).

Error messages
This doesn't directly cause error messages, but breaks integration with just_audio_background

Expected behavior
The currentIndex should be set to 0 when the media is playing.

[bug] broadcastPlaybackEvent : No such interface supported

Which API doesn't behave as documented, and how does it misbehave?

The error occurs when playing a flac file from http url.

It is thrown by this line of code: L520

This code throws a No such interface supported error when trying to use the win api's MediaPlayer.PlaybackSession().BufferingProgress() (inside BufferingProgress).

This causes all of Win's music playback data to be lost due to this error, but in reality this BufferingProgress does very little for the data.

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

Only change the music url to flac in some of this repo's example, and this error occurs

Unable To Play AAC-LC Encoding Files

Which API doesn't behave as documented, and how does it misbehave?
I am trying to use the record package to record microphone audio, and then play it. I am encoding the audio file using the AAC-LC encoder that the package provides. The audio file is saved as an m4a, and it works well. The audio file can be read and played on an android application using the just_audio no problem.

But on desktop, with just_audio_windows the file is unable to be read

Issue with Non-ASCII Characters in File Path for "just_audio_windows"

Description:
When attempting to load audio files with Unicode characters in their names, such as "дуу.mp3," the "just_audio_windows" seems to encounter issues.

Steps to Reproduce:

Install the latest version of "just_audio_windows."
Use the following code to load an audio file with a Unicode name:

///not actual production code but example
import 'package:just_audio/just_audio.dart';

void loadUnicodeAudio() {
  final audioPlayer = AudioPlayer();
  audioPlayer.setFilePath('D:/examplefolder/дуу.mp3');
  // Add code for audio playback.
}
void loadUnicodeAudio2() {
  final audioPlayer = AudioPlayer();
  audioPlayer.setFilePath('D:/дуу/song.mp3');
  // Add code for audio playback.
}

Expected Behavior:
The "just_audio_windows" and "just_audio" should load and play audio files with Unicode characters in their names without any errors.

Actual Behavior:
[just_audio_windows] Item error: The system cannot find the path specified.
Instead, the audio player throws an exception or fails to load the file properly when Unicode characters are present in the file name.

Environment:
just_audio : ^0.9.31
just_audio_windows: ^0.2.0

Flutter version: 3.10.2
Operating System: Windows 11

FAQ:

Do I really need to submit a minimal reproduction project for a bug?
A: Yes, I understand the importance of providing a minimal reproduction project, and I'll work on creating one ASAP to help resolve the issue.

I will also explore potential solutions and investigate whether it's a platform-specific issue or related to the "just_audio_windows" extension itself. If the problem persists, I'll reach out to the maintainers of the "just_audio_windows" extension on GitHub with this detailed report.

Audio balance is set to right channel only

Which API doesn't behave as documented, and how does it misbehave?
setPitch()
The setPitch function changes the audio balance instead of the pitch.

Minimal reproduction project
Minimal reproduction

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

Build the project for windows
Click on Play
Observe audio only coming from the right channel
Use the different buttons to change pitch
Observe audio balance changing instead of pitch

Expected behavior
With a default player I expect the audio to be stereo as in the case with just_audio for other platforms.
I also expect the setPitch() function to change the pitch instead of audio balance.

Looking through the code in player.hpp it seems to me that this part is the cause.

AudioBalance as described here seems to not change the pitch, unfortunately I couldn't find an alternative for it.

WAV data of initially unknown length through `StreamAudioSource` is silent for prolonged periods of time before playing

When an AudioPlayer plays from a StreamAudioSource that returns a response with a stream containing WAV PCM data and contentLength: null, sourceLength: null, offset: null to indicate that the overall length of the stream is not currently known, e.g. background sound that is continually generated, the audio is not played immediately. It may instead be played several minutes after the request completes, even for short amounts of data, e.g. 1 second long.

[bug] broadcastPlaybackEvent : No such interface supported

The error occurs when playing a flac file.

It is thrown by this line of code: L520

This code throws a No such interface supported error when trying to use the win api's MediaPlayer.PlaybackSession().BufferingProgress() (inside BufferingProgress).

This causes all of Win's music playback data to be lost due to this error, but in reality this BufferingProgress does very little for the data.

Seek doesn't work properly on long videos

Which API doesn't behave as documented, and how does it misbehave?
The seek() method doesn't behave as expected on Windows. Calling seek to a specific position seems to update the position data in the positionDataStream, but the actual audio continues playing from the original position.

Minimal reproduction project
The just_audio example.

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

Press the Play button.
Seek somewhere far ahead using the seek bar - e.g. to the halfway point.
The bar updates, but audio continues playing from the beginning.

If you seek a small amount forward (e.g. 5 mins), the seek seems to behave as expected.

Error messages
No errors displayed

Expected behavior
The audio should always match the seek position on screen.

Screenshots
The screen looks as expected, but the audio played doesn't match. E.g. screen shows 45 mins in, but you're actually in the first minute of audio.

'IUnknown': ambiguous symbol when running app

Hello, I recently just came back to a project I was working on involving this plugin. This plugin was working a while ago, but just today I encountered a new problem when trying to run my project.

flutter run
and selecting 'Windows' causes the build to fail with the following errors:

After a little bit of research, it seems that the generated files for the plugin do not specify which 'IUnkown' to use. This is way beyond me, I have no clue how to fix this. I'm not even sure if it's related to this plugin, or if it is an issue on my end. I have no clue how to reproduce this, and this issue is preventing my windows version of the app to not be able to play sound. I was planning on making my repo public after double checking that the basic functionality worked, but I ran into this issue. Removing this plugin from my pubspec.yaml resolves the errors, but then audio playback does not work. Any help would be appreciated, thanks!
