Flutter VideoPlayer 无法播放 YouTube 视频

Question

我正在开发 flutter 应用程序并使用 ext_video_player 来播放 YouTube 视频。当我在视频播放器上播放 channel 视频时，它不起作用。但我添加了 YouTube 上的任何视频，播放器正在工作。为什么会这样？

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(不起作用)“https://www.youtube.com/watch?v=GoqggeA-ctA”

问题是由 YouTube 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，然后播放器播放我的视频。上传格式问题。
