如何在颤音中播放rtsp视频流？

Question

这是我的代码，我正在尝试使用flutter vlc player ，但是它不起作用，所以任何方法都可以帮助我解决这个问题，或者我可以用另一种方式显示流？。

所以你们可以给我任何建议或者小例子。我正试图从过去的两个小时开始解决这个问题，但没有进展。

import 'package:flutter/material.dart';
import 'package:flutter_vlc_player/flutter_vlc_player.dart';
import 'package:flutter_vlc_player/vlc_player.dart';
import 'package:flutter_vlc_player/vlc_player_controller.dart';
void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        visualDensity: VisualDensity.adaptivePlatformDensity,
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key}) : super(key: key);

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

class _MyHomePageState extends State<MyHomePage> {
  VlcPlayerController _videoPlayerController;

  @override
  void initState() {
    super.initState();

    _videoPlayerController = VlcPlayerController.network(
      'rtsp://viewer:aeDoPhiucees3gohshie@173.249.14.110:27954/axis-media/media.amp?videocodec=h264&fps=15&audio=1&resolution=640x480',
      hwAcc: HwAcc.FULL,
      autoPlay: false,
      options: VlcPlayerOptions(),
    );
  }

  @override
  void dispose() async {
    super.dispose();
    await _videoPlayerController.stopRendererScanning();
    await _videoPlayerController.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(),
      body: Center(
        child: VlcPlayer(
          controller: _videoPlayerController,
          aspectRatio: 16 / 9,
          placeholder: Center(child: CircularProgressIndicator()),
        ),
      ),
    );
  }
}

下面是一个对我有用的小例子。我认为问题在于，在较新的版本中，必须立即初始化Controller。

我在这段代码中唯一的问题是高级选项不起作用。不幸的是，很难找到好的信息。

import 'package:flutter/material.dart';
import 'package:flutter_vlc_player/flutter_vlc_player.dart';
import 'package:flutter_vlc_player/src/vlc_player_controller.dart';

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

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @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, required this.title}) : super(key: key);

  final String title;

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

class _MyHomePageState extends State<MyHomePage> {
  VlcPlayerController _vlcViewController = new VlcPlayerController.network(
    "rtsp://192.72.1.1/liveRTSP/av4",
    autoPlay: true,
  );

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            new VlcPlayer(
              controller: _vlcViewController,
              aspectRatio: 16 / 9,
              placeholder: Text("Hello World"),
            ),
          ],
        ),
      ),
    );
  }
}

查看这个库：https://pub.dev/packages/flutter_playout。它确实支持他。
