Steps to Reproduce

  1. Run flutter create bug2.
  2. Add video_player: ^1.0.1 to the dependencies: in pubspec.yaml.
  3. Replace lib/main.dart with this:
import 'package:flutter/material.dart';
import 'package:video_player/video_player.dart';

void main() {
  runApp(MyApp());
}

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

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key, this.title}) : super(key: key);
  final String title;

  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  final _controller = VideoPlayerController.network(
      'https://soundbible.com/grab.php?id=2067&type=mp3');

  @override
  void initState() {
    super.initState();
    print('initialize()');
    final initFuture = _controller.initialize();

    // Start playing if this is the first media
    initFuture.then((_) {
      print('initialize() DONE, refreshing UI');
      setState(() {}); // so the player is shown
      final delay = 2;
      print('scheduling play() in $delay seconds');
      Future.delayed(Duration(seconds: delay), () {
        print('play()');
        _controller.play().then((_) => print('play() future DONE'));
      });
    });
  }

  @override
  void dispose() {
    print('dispose()');
    _controller.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: _controller.value.initialized
            ? AspectRatio(
                aspectRatio: _controller.value.aspectRatio,
                child: VideoPlayer(_controller),
              )
            : CircularProgressIndicator(),
      ),
    );
  }
}

Expected results: The sound can be heard 2 seconds after initialization

Actual results: No sound.

Extended explanation and findings

Since this seems to be some sort of timing issue, I guess that for different environments it can take different times to make it fail. For me with delay 0 or 1 it works reliably and with 2 or more if fails reliably.

It fails on android but works fine in web (at least when using an assert() constructor instead of a network() one), so I'm guessing this is an android-only issue.

I came across this bug when implementing some playlist, I preload (pre-initialize()) several sounds before start playing and then I play one after the other, and I found after a few sounds the rest would not play (or sometimes one didn't play, the next does, and then nothing plays again). My guess is this whole problem comes from the fact that later sound are just more apart from the moment they were initialized, but I will add a link to an extended test case playing one after the other.

Video files don't seem to be affected, playing a 200ms video works as expected, this is an audio-only issue.

Also longer audio files don't seem to be affected, for example replacing the audio with a 5 seconds audio (like this
https://soundbible.com/grab.php?id=1634&type=mp3) makes it work, even with very big delays (I tried up to 20 seconds).
