android - 打开流媒体视频时出错

Question

我正在尝试通过提供视频的 url 打开视频流。我正在使用 VideoView。这是我的代码:

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);        
        VideoView videoView = (VideoView) findViewById(R.id.stream_video_view);
        videoView.setVisibility(View.VISIBLE);
        MediaController mc = new MediaController(this);     
        mc.setAnchorView(videoView);
        mc.setMediaPlayer(videoView);
        videoView.setMediaController(mc);
        Uri uri = Uri.parse("http://172.16.154.106:8080");
        videoView.setVideoURI(uri);
        videoView.requestFocus();
        videoView.start();
    }     
}

LogCat:

执行此操作时，我没有收到任何错误，但出现了一个标题为“无法播放视频”和消息“抱歉，无法播放此视频”的对话框。为什么我的代码不起作用的任何想法？

Answer 1

首先检查您是否在 list 中添加了 INTERNET 权限。

接下来检查您的视频格式的扩展名是什么。

这link显示 Android 手机和平板电脑支持的文件，并提供编解码器和文件扩展名信息。但是，Android 应用程序可以使用任何 Android 设备提供的媒体编解码器，或第三方公司开发的其他媒体编解码器。因此，如果您想在 Android 上播放视频，请寻找多格式视频播放器或将视频转换为 Android 兼容格式。
