Flutter视频播放器对Vimeo video抛出异常

如何解决Flutter视频播放器对Vimeo video抛出异常

我正在尝试使用视频播放器库在Flutter应用中播放vimeo视频。

我遵循了video_player的示例。当我启动屏幕和Android模拟器时，我将抛出以下异常...。

我的代码如下...

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

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

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

class _HomeScreenState extends State<HomeScreen> {

  final _key = UniqueKey();  
  VideoPlayerController _controller;

  @override
  void initState() { 
    super.initState();
    _controller = VideoPlayerController.network(
        'https://vimeo.com/476379279')
      ..initialize().then((_) {
        // Ensure the first frame is shown after the video is initialized,even before the play button has been pressed.
        setState(() {});
      });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: Colors.Background,appBar: AppBar(
        centerTitle: true,backgroundColor: Colors.Primary,title: Text(
          'HOME',style:Styles.ButtonTextStyle.copyWith(color: Colors.PrimaryContrast)
        )
      ),body: Center(
        child: _controller.value.initialized
          ? AspectRatio(
              aspectRatio: _controller.value.aspectRatio,child: VideoPlayer(_controller),)
          : Container(),),floatingActionButton: FloatingActionButton(
        onPressed: () {
          setState(() {
            _controller.value.isPlaying
                ? _controller.pause()
                : _controller.play();
          });
        },child: Icon(
          _controller.value.isPlaying ? Icons.pause : Icons.play_arrow,)
      )
    );
  }
} 

解决方法

您不能在video_player中播放视频Vimeo链接。

您必须提供以视频格式结尾的视频源。

示例http://www.sample-videos.com/video123/mp4/720/big_buck_bunny_720p_20mb.mp4

这可以帮助您：video_player example

如果你想获得 vimeo 视频的 mp4 链接，那么在 url 搜索中 [https://player.vimeo.com/video/13083500/config] 以及您想要编辑的任何视频，都没有链接中的视频。 在这里，您将获得 json 文件，从源代码中获取 mp4 链接。 快乐编码..
