无法使用 RTSP 流在 VideoView 中播放 YouTube 视频

Question

我正在编写一个使用 VideoView 播放 YouTube 视频的应用程序。

这是我的代码：

VideoView videoView = (VideoView)findViewById(R.id.video_view);
videoView.setVideoURI(Uri.parse(filePath));
videoView.setMediaController(new MediaController(this));
videoView.requestFocus();
videoView.start();

该代码适用于此网址：“http://commonsware.com/misc/test2.3gp”，

但不适用于此网址（通过 API 来自 YouTube）： “rtsp://v4.cache7.c.youtube.com/CjsLENy73wIaMgl4q-dkJkOfrRMYDSANFEIXZ29vZ2xlLW1vdW50YWludmlldy0wLjFIBlIGdmlkZW9zDA==/0/0/0/video.3gp”

错误日志如下。请注意：我想控制播放，所以我不是在寻找涉及使用意图启动独立 YouTube 播放器的解决方案。当我这样做时，YouTube 视频会播放，但这不是我需要做的。

真的很感激任何帮助。

Answer 1

我们遇到了这个问题，发现这是防火墙问题。看来 UDP 被阻止了。
在另一篇文章中看到其他人说这对他们来说适用于移动数据连接，但不适用于 wifi。可能有同样的问题 - wifi 防火墙设置。

Answer 2

将 Internet 权限添加到清单文件中

 <uses-permission android:name="android.permission.INTERNET" />

，同时请尝试以下 URI：

rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov
