Question

我想在特定页面上以我的应用为背景播放YouTube视频。这意味着视频/播放器不可见。仅用于音频。

该程序包称为youtube_player_flutter ^ 4.1.0。我已经在Android设备上测试了相同的代码，并且可以正常工作。但是，在Ios上却没有，当我返回上一页后，我收到此错误消息：

iOS => call stop, playerId 02a9ae4c-0fac-482d-a9f6-d668feffa2da

以下代码在android上运行：

YoutubePlayer(
  context: context,
  videoId: _videoId,
  flags: YoutubePlayerFlags(
    hideControls: true,
    autoPlay: true,
  ),
  onPlayerInitialized: (YoutubePlayerController controller) {
    _videoController = controller;
    debugPrint("playing...");
  },
)

我会有所帮助。

Answer 1

İos模拟器对youtube播放器具有尴尬的抵抗力。在真实设备上尝试可能会有所帮助
