我在如何从 Google Drive 链接播放视频中找到了一些使用视频播放器的示例？我也尝试过这样，但发生源错误。

216) E/ExoPlayerImplInternal(14285)：在 android.os.HandlerThread.run(HandlerThread.java:65) E/ExoPlayerImplInternal(14285)：引起：com.google.android.exoplayer2.source.UnrecognizedInputFormatException：没有可用的提取器（FlvExtractor、FlacExtractor、WavExtractor、FragmentedMp4Extractor、Mp4Extractor、AmrExtractor、PsExtractor、OggExtractor、TsExtractor、MatroskaExtractor、AdtsExtractor、Ac3Extractor、Ac4Extractor、Mp3Extractor）可以读取流。E/ExoPlayerImplInternal(14285)：在 com.google.android.exoplayer2.source.BundledExtractorsAdapter.init(BundledExtractorsAdapter.java:92) E/ExoPlayerImplInternal(14285)：在 com.google.android.exoplayer2.source.ProgressiveMediaPeriod$ExtractingLoadable。加载（ProgressiveMediaPeriod.java:1024）E/ExoPlayerImplInternal（14285）：在 com.google.android.exoplayer2。

这是我的代码：

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

class VideoApp extends StatefulWidget {
  @override
  _VideoAppState createState() => _VideoAppState();
}

class _VideoAppState extends State<VideoApp> {
  VideoPlayerController _controller;

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

    _controller = VideoPlayerController.network(
        'https://drive.google.com/uc?export=view&id=1mlIaLXrBdqdKCG5WvPGiLpQRNUTKqVOf')
      ..initialize().then((_) {      
        setState(() {});
      });
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Video Demo',
      home: Scaffold(
        body: Center(
          child: _controller.value.isInitialized
              ? 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,
          ),
        ),
      ),
    );
  }

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

这真让我抓狂。请帮帮我
