Describe the bug Everything is ok in the debug mode，but there is no video playback under releas mode;

Minimal reproducible code

import 'package:dart_vlc/dart_vlc.dart';
import 'package:flutter/material.dart';
void main() {
  DartVLC.initialize(useFlutterNativeView: true);
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key, required this.title}) : super(key: key);

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  final videoPlayer = Player(id: 0,registerTexture: false);
  final audioPlayer = Player(id:1);

  @override
  void initState() {
      videoPlayer.open( Media.asset(
          'assets/video.webm'
      ),autoStart: true);
      videoPlayer.setPlaylistMode(PlaylistMode.loop);
      audioPlayer.open( Media.asset(
          'assets/bailuguiting.mp3'
      ),autoStart: true);
    audioPlayer.setPlaylistMode(PlaylistMode.loop);
    super.initState();
  }

  @override
  void dispose() {
    videoPlayer.dispose();
    audioPlayer.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return NativeVideo(
      player: videoPlayer,
        height: double.infinity,
        width: double.infinity,
        fit: BoxFit.cover,

Add await before DartVLC.initialize.

alexmercerind commented 2 years ago

Please close, if fixed.

meng-fucius commented 2 years ago

It works, thanks.

mcquenji commented 1 year ago

I am not sure if should open a new issue or not, but it seems this issue is back again, and using the latest version the initialize method does not return a Future. It works fine in debug mode but in release mode it just shows a blank screen. Although I can hear the audio...

Have I missed anything?

flutter --version

Flutter 3.7.12 • channel stable • https://github.com/flutter/flutter.git Framework • revision 4d9e56e694 (4 weeks ago) • 2023-04-17 21:47:46 -0400 Engine • revision 1a65d409c7 Tools • Dart 2.19.6 • DevTools 2.20.1

My main method:

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  DartVLC.initialize();
  await windowManager.ensureInitialized();

  var logDisk = LogDiskService();

  Logger.root.onRecord.listen((event) async {
    if (kDebugMode) print(event);
    await logDisk.write(event.toString());
  });

  await SystemTheme.accentColor.load();

  doWhenWindowReady(() {
    appWindow.title = "Testytest";
    appWindow.alignment = Alignment.center;
    appWindow.show();
  });

  runApp(const ProviderScope(child: App()));
}

These are the error messages if they help:

[00000267561de8b0] main vout display error: Failed to set on top
