import 'package:aws_kinesis_video_archived_media_api/kinesis-video-archived-media-2017-09-30.dart';

void main() {
  // 初始化 KinesisVideoArchivedMedia 服务，指定区域
  final service = KinesisVideoArchivedMedia(region: 'eu-west-1');
}

完整示例 Demo

以下是一个完整的示例代码，展示了如何使用 aws_kinesis_video_archived_media_api 插件来访问 Amazon Kinesis Video Streams 的存档媒体。

import 'package:flutter/material.dart';
import 'package:aws_kinesis_video_archived_media_api/kinesis-video-archived-media-2017-09-30.dart';

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

class MyApp extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter AWS Kinesis Video Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(title: 'Flutter AWS Kinesis Video Demo'),
    );
  }
}

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

  final String title;

  [@override](/user/override)
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  final service = KinesisVideoArchivedMedia(region: 'eu-west-1');

  Future<void> fetchArchivedMedia() async {
    try {
      // 这里可以添加更多的方法调用以获取存档媒体
      print('Fetching archived media...');
    } catch (e) {
      print('Error fetching archived media: $e');
    }
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: ElevatedButton(
          onPressed: fetchArchivedMedia,
          child: Text('Fetch Archived Media'),
        ),
      ),
    );
  }
}

在Flutter中使用AWS Kinesis Video Archived Media API来访问和管理存档的媒体流，你可以按照以下步骤进行。由于Flutter并没有官方的AWS Kinesis Video Archived Media插件，你需要使用Dart的AWS SDK来与AWS服务进行交互。

1. 安装依赖

首先，你需要在pubspec.yaml文件中添加aws_client依赖：

dependencies:
  flutter:
    sdk: flutter
  aws_client: ^0.1.0

然后运行flutter pub get来安装依赖。

2. 配置AWS凭证

你需要在Flutter应用中配置AWS凭证。可以通过环境变量、AWS配置文件或直接在代码中提供凭证。

import 'package:aws_client/aws_client.dart';

final awsClient = AwsClient(
  region: 'us-west-2', // 你的AWS区域
  credentials: AwsCredentials(
    accessKey: 'your-access-key',
    secretKey: 'your-secret-key',
  ),
);

3. 使用AWS Kinesis Video Archived Media API

你可以使用awsClient来调用AWS Kinesis Video Archived Media API。以下是一个获取存档媒体流的示例：

import 'package:aws_client/aws_client.dart';

Future<void> getArchivedMedia() async {
  final client = awsClient.kinesisVideoArchivedMedia;

  final response = await client.getHLSStreamingSessionURL(
    streamName: 'your-stream-name',
    playbackMode: PlaybackMode.LIVE, // 或者 PlaybackMode.ON_DEMAND
  );

  print('HLS Streaming URL: ${response.hlsStreamingSessionURL}');
}

4. 处理响应

你可以根据API的响应来处理获取到的媒体流URL，并在Flutter应用中使用它来播放视频。

import 'package:flutter/material.dart';
import 'package:video_player/video_player.dart';

class VideoPlayerScreen extends StatefulWidget {
  final String videoUrl;

  VideoPlayerScreen({required this.videoUrl});

  [@override](/user/override)
  _VideoPlayerScreenState createState() => _VideoPlayerScreenState();
}

class _VideoPlayerScreenState extends State<VideoPlayerScreen> {
  late VideoPlayerController _controller;

  [@override](/user/override)
  void initState() {
    super.initState();
    _controller = VideoPlayerController.network(widget.videoUrl)
      ..initialize().then((_) {
        setState(() {});
      });
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Video Player'),
      ),
      body: _controller.value.isInitialized
          ? AspectRatio(
              aspectRatio: _controller.value.aspectRatio,
              child: VideoPlayer(_controller),
            )
          : Center(child: CircularProgressIndicator()),
      floatingActionButton: FloatingActionButton(
        onPressed: () {
          setState(() {
            _controller.value.isPlaying
                ? _controller.pause()
                : _controller.play();
          });
        },
        child: Icon(
          _controller.value.isPlaying ? Icons.pause : Icons.play_arrow,
        ),
      ),
    );
  }

  [@override](/user/override)
  void dispose() {
    _controller.dispose();
    super.dispose();
  }
}

5. 运行应用

最后，你可以在Flutter应用中调用getArchivedMedia函数，获取到视频流的URL，并将其传递给VideoPlayerScreen来播放视频。

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

class MyApp extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('AWS Kinesis Video Archived Media'),
        ),
        body: Center(
          child: ElevatedButton(
            onPressed: () async {
              await getArchivedMedia();
            },
            child: Text('Get Archived Media'),
          ),
        ),
      ),
    );
  }
}
