我正在开发颤振应用程序并使用 ext_video_player 播放 youtube 视频。当我在视频播放器上播放我的频道视频时，它不起作用。但是我添加了来自 youtube 的任何视频，播放器正在工作。为什么会发生？

import 'package:ext_video_player/ext_video_player.dart';

controller = VideoPlayerController.network(
    //example video
    'https://www.youtube.com/watch?v=TdrL3QxjyVw'  
    //my video
    //'https://www.youtube.com/watch?v=GoqggeA-ctA'
      )
    ..initialize().then((value) {
      controller.setLooping(true);
      controller.play();
      widget.sets.controller = controller;
      widget.onInitialized();
    });

Widget build(BuildContext context) => SizedBox(
    child: controller.value.initialized
        ? VideoPlayer(controller)
        : Center(child: CircularProgressIndicator()),
  );
  • 工作视频“https://www.youtube.com/watch?v=TdrL3QxjyVw”
  • 我的视频（无效）“https://www.youtube.com/watch?v=GoqggeA-ctA”

错误 ：

问题是由 youtube 的上传格式引起的。当我使用 h.264 + aac 编解码器将 mp4 文件转换为 mp4 并上传 youtube 时，播放器播放我的视频。它的上传格式问题。

使用带有版本的 youtube_player_flutter 包：youtube_player_flutter: ^ 6.1.1

这是我从 youtube 频道检索视频的代码示例

class Video {
  final String id;
  final String title;
  final String thumbnailUrl;
  final String channelTitle;

  Video({
    this.id,
    this.title,
    this.thumbnailUrl,
    this.channelTitle,
  });

  factory Video.fromMap(Map<String, dynamic> snippet) {
    return Video(
      id: snippet['resourceId']['videoId'],
      title: snippet['title'],
      thumbnailUrl: snippet['thumbnails']['high']['url'],
      channelTitle: snippet['channelTitle'],
    );
  }
}
