如何將YouTube網址轉換爲RTSP網址？

在我的項目中，我想下載Youtube網址並在媒體播放器中播放它，但就我搜索的內容而言，我有一個想法，即Youtube網址只有在它們被轉換爲RTSP文件時才能播放。我不知道如何做到這一點。如果你給我一個樣本項目，這將是非常有幫助的。如何將YouTube網址轉換爲RTSP網址？

public class Video_Media_PlayerActivity extends Activity { 
    private static final String TAG = "VideoViewDemo"; 

    private VideoView mVideoView; 
    private EditText mPath; 
    private ImageButton mPlay;

我可以給你一個名字：JDownloader是關於一個下載管理器的開源項目，也是用Java編寫的，並從Youtube下載視頻時，它完美的作品，也許你可以下載源代碼並搜索正確的模塊或者在他們的論壇中提問。 jdownloader.org – Micro

使用http://gdata.youtube.com/feeds/mobile/videos/T9W4jgq9RfQ API

public class MainActivity extends Activity { 
String video_id; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 


     try {  
     String link = "http://www.youtube.com/watch?v=T9W4jgq9RfQ&feature=related"; 
      String pattern = "(?:videos\\/|v=)([\\w-]+)"; 

      Pattern compiledPattern = Pattern.compile(pattern); 
      Matcher matcher = compiledPattern.matcher(link); 

      if(matcher.find()){ 
       System.out.println(matcher.group().substring(2)); 
video_id=matcher.group().substring(2); 
      } 

      DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); 
      DocumentBuilder db = dbf.newDocumentBuilder(); 


      Document doc1=db.parse("http://gdata.youtube.com/feeds/mobile/videos/"+video_id); 

      Element rsp = (Element)doc1.getElementsByTagName("media:content").item(1); 

      String anotherurl=rsp.getAttribute("url"); 
      System.out.println("my "+anotherurl); 
     // Element rsp = (Element)doc1.getElementsByTagName("media:content").item(1); 
     } catch (Exception e) { 
      System.out.println("Pasing Excpetion = " + e); 
     } 
    }
