void main() {
DartVLC.initialize();

}
final player = Player(id: 69420);
For passing VLC CLI arguments, use commandlineArguments
argument.
final player = Player(
id: 69420,
commandlineArguments: ['--no-video'],
);
final file = Media.file(File('C:/music.mp3'));
final asset = Media.asset('assets/audio/example.mp3');
final network = Media.network('https://www.example.com/music.aac');
// Clip [Media] playback duration.
final media2 = Media.network(
'https://www.example.com/music.aac',
startTime: Duration(seconds: 20),
stopTime: Duration(seconds: 60),
);
final playlist = Playlist(
medias: [
Media.file(File('C:/music.mp3')),
Media.file(File('C:/audio.mp3')),
Media.asset('assets/audio/example.mp3'),
Media.network('https://www.example.com/music.aac'),
],
);
player.open(
Media.file(File('C:/music0.mp3')),
autoStart: true, // default
);
player.open(
Playlist(
medias: [
Media.file(File('C:/music0.mp3')),
Media.file(File('C:/music1.mp3')),
Media.file(File('C:/music2.mp3')),
],

Show Video
in the Widget
tree.
class _MyAppState extends State<MyApp> {
@override
Widget build(BuildContext context) {
return Scaffold(
body: Video(
player: player,
height: 1920.0,
width: 1080.0,
scale: 1.0, // default
showControls: false, // default
),
);
}
}
By default, Video
widget's frame size will adapt to the currently playing video.
To override this & define custom video frame size, pass videoDimensions
argument while instanciating Player
class as follows.
Player player = Player(
id: 69420,
videoDimensions: const VideoDimensions(640, 360),
);
player.setUserAgent(userAgent);
Media media = Media.network(
'https://www.example.com/media.mp3',
parse: true,
timeout: Duration(seconds: 10),
);
Map<String, String> metas = media.metas;
(Same can be retrieved directly from Player
instance without having to rely on stream).
Listen to currently loaded media & playlist index changes.
player.currentStream.listen((CurrentState state) {
state.index;
state.media;
state.medias;
state.isPlaylist;
});
Listen to playback position & media duration.
player.positionStream.listen((PositionState state) {
state.position;
state.duration;
});
Listen to playback states.
player.playbackStream.listen((PlaybackState state) {
state.isPlaying;
state.isSeekable;
state.isCompleted;
});
Listen to volume & rate of the Player
.
player.generalStream.listen((GeneralState state) {
state.volume;
state.rate;
});
Listen to dimensions of currently playing Video
.
player.videoDimensionsStream.listen((VideoDimensions video) {
video.width;
video.height;
});
Listen to buffering progress of the playing Media
.
player.bufferingProgressStream.listen(
(double event) {
this.setState(() {
this.bufferingProgress = event;
});
},
);
Create using preset.
Equalizer equalizer = Equalizer.createMode(EqualizerMode.party);
player.setEqualizer(equalizer);
Create custom equalizer.
Equalizer equalizer = Equalizer.createEmpty();
equalizer.setPreAmp(10.0);
equalizer.setBandAmp(31.25, -10.0);
equalizer.setBandAmp(100.0, -10.0);
player.setEqualizer(equalizer);
Get equalizer state.
equalizer.preAmp;
equalizer.bandAmps;
Broadcasting to localhost.
final broadcast = Broadcast.create(
id: 0,
media: Media.file(File('C:/video.mp4')),
configuration: BroadcastConfiguration(
access: 'http',
mux: 'mpeg1',
dst: '127.0.0.1:8080',
vcodec: 'mp1v',
vb: 1024,
acodec: 'mpga',
ab: 128,
),
);
broadcast.start();
Dispose the Broadcast
instance to release resources.
broadcast.dispose();
final record = Record.create(
id: 205,
media: Media.network('https://www.example.com/streaming-media.MP3'),
pathFile: '/home/alexmercerind/recording.MP3',
);
record.start();
Everything is already set up.
For using this plugin on Linux, you must have VLC & libVLC installed.
On Ubuntu/Debian:
sudo apt-get install vlc
sudo apt-get install libvlc-dev
On Fedora:

sudo dnf install vlc
sudo dnf install vlc-devel
Consider sponsoring this project. Maintenance of open-source software & libraries is severely under-paid or not paid at all.
Writing C++ & native code is a very tedious process.
BIG thanks to @jnschulze for his awesome contributions to this project & to the Flutter engine itself like adding texture support & adding macOS support here. I have learnt a lot about modern C++ & good-practices when writing code from you, thanks a lot for your guidances, reviews, work & donation. I'm really really thankful to you.
BIG thanks to @DomingoMG for adding Record
and Chromecast
classes. Also, thanks a lot for donation to the project & giving me motivation to start building this. I would've never attempted this if you didn't motivate me. And now that it started, dart_vlc
has grown a lot.
Thanks to @tomassasovsky for adding visual controls to Video
widget.
Thanks to following members of libVLC community (irrespective of the order) for giving general ideas about libVLC APIs:
Finally, thanks to the VideoLAN team for creating libVLC & libVLC++. Really great guys really great at their work.
The code in the project is nicely arranged and follows the clean architecture.
Contributions to the project are open, it will be appreciated if you discuss the bug-fix/feature-addition in the issues first.

There aren't any media (audio or video) playback libraries for Flutter or Dart on Windows/Linux yet. So, this project is all about that. As one might be already aware, VLC is one of the best media playback tools out there.
So, now you can use it to play audio or video files from Flutter or Dart apps.
As the project has grown, awesome people from community have added support for iOS & macOS aswell.
You can see an example project here.
