我非常想在我的 android 应用程序中播放 mp4 视频。我什至为它写了一些代码：

String sourceUrl = "http://tvstream.cn.ru/storage/1kanal/20120530/"
       + "1kanal-20120530-01-14-00-20120530-03-16-00.mp4";

final VideoView videoView = (VideoView) findViewById(R.id.videoView);
getWindow().setFormat(PixelFormat.TRANSLUCENT);

final MediaController mediaController = new MediaController(this);
mediaController.setMediaPlayer(videoView);
videoView.setMediaController(mediaController);
videoView.setVideoURI(Uri.parse(sourceUrl));

videoView.setOnPreparedListener(new OnPreparedListener() {

    public void onPrepared(MediaPlayer mp) {
        videoView.requestFocus();
        videoView.start();
        mediaController.show();
    }
});

但是没有任何效果:(当我在模拟器（Android 2.3.3）中启动我的应用程序时，我有一些奇怪的堆栈跟踪和一些常见的错误代码：

经过几个小时的谷歌搜索和实验后，我决定尝试在真实设备上启动我的应用程序并观看 logcat：

我尝试查找有关“OMX.qcom.video.decoder.avc] ERROR(0x8000100a, 0)”的内容，但没有发现任何有趣的内容。关于“无法在客户端打开文件，尝试服务器端”问题 stackoverflow 有很多答案，但没有人帮助。

当我在 ICS（在模拟器中）上启动这个应用程序时，我遇到了类似的错误：

据我所知，Android 支持播放使用 h264 解码的视频（http://developer.android.com/guide/appendix/media-formats.html）。所以，谁能告诉我我做错了什么。

可能您的文件正在使用不受支持的配置文件，请注意官方媒体格式页面仅列出H.264 AVC 支持的基线配置文件。

尝试按照此 stackoverflow question中的建议对指定基线配置文件的视频进行转码，即如果您的容器是 MP4 运行：

ffmpeg -i yourfile.mp4 -c:v libx264 -profile:v baseline -level 1 yourfile_BaselineProfile.mp4

如果这行得通，那在您的代码中不是问题，您只需要使用受支持的格式。

尝试这个

File clip=new File(Environment.getExternalStorageDirectory(),
                       "test.mp4");

    if (clip.exists()) {
      video=(VideoView)findViewById(R.id.video);
      video.setVideoPath(clip.getAbsolutePath());

      ctlr=new MediaController(this);
      ctlr.setMediaPlayer(video);
      video.setMediaController(ctlr);
      video.requestFocus();
      video.start();

VideoView 类不允许播放 MP4 文件格式的视频。请通过此链接了解 Android 媒体格式。尝试使用Daroon Player查看您的视频
