android - 如何在Android中播放远程网址的实时视频流？

我已经创建了一个在特定时间间隔触发通知服务的函数。通知可以是文本、图像或视频…
现在，对于视频，我先下载然后播放，这需要更多的时间…那么有没有什么机制可以直接从远程url播放视频？？？？
请帮帮我…
我急需尽快得到答案…
提前谢谢……。
看看我的代码片段：

public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.notificationvideo);

    mVideoView = (VideoView) findViewById(R.id.video);
    //pd=ProgressDialog.show(this, "Loading...", "Please Wait...",true,false);
    playVideo();
    //pd.dismiss();

    img_back = (ImageView) findViewById(R.id.img_back);
    img_back.setOnClickListener(new View.OnClickListener()
     {
        public void onClick(View v)
        {
                Intent int_back=new Intent(NotificationsVideoActivity.this,MyChannelsActivity.class);
                startActivity(int_back);
                finish();
        }
    });
}

private void playVideo()
{
    try {
         path = getIntent().getStringExtra("url");

        Log.v(TAG, "path: " + path);
        if (path == null || path.length() == 0) {
            Toast.makeText(NotificationsVideoActivity.this, "File URL/path is empty",Toast.LENGTH_LONG).show();

        }
        else
        {
            // If the path has not changed, just start the media player
            if (path.equals(current) && mVideoView != null)
            {
                mVideoView.start();
                mVideoView.requestFocus();
                return;
            }
            current = path;
            mVideoView.setVideoPath(getDataSource(path));
            mVideoView.start();
            mVideoView.requestFocus();

        }
    }
    catch (Exception e)
    {
        Log.e(TAG, "error: " + e.getMessage(), e);
        if (mVideoView != null)
        {
            mVideoView.stopPlayback();
        }
    }
}

private String getDataSource(String path) throws IOException
{
    if (!URLUtil.isNetworkUrl(path))
    {
        return path;
    }
    else
    {
        URL url = new URL(path);
        URLConnection cn = url.openConnection();
        cn.connect();
        InputStream stream = cn.getInputStream();
        if (stream == null)
            throw new RuntimeException("stream is null");
        File temp = File.createTempFile("mediaplayertmp", "mp4");
        temp.deleteOnExit();
        String tempPath = temp.getAbsolutePath();
        FileOutputStream out = new FileOutputStream(temp);
        byte buf[] = new byte[128];
        //byte buf[] = new byte[8192];

        do
        {
            int numread = stream.read(buf);
            if (numread <= 0)
                break;
            out.write(buf, 0, numread);
        } while (true);

        try
        {
            stream.close();
        }
        catch (IOException ex)
        {
            Log.e(TAG, "error: " + ex.getMessage(), ex);
        }
        return tempPath;

    }
}

最佳答案

试试这个-

String path="http://www.ted.com/talks/download/video/8584/talk/761";
String path1="http://commonsware.com/misc/test2.3gp";

Uri uri=Uri.parse(path1);

VideoView video=(VideoView)findViewById(R.id.VideoView01);
video.setVideoURI(uri);
video.start();
