title: Unable to play rtsp using videoview in android
body: <p>I have set up a RTSP server using VLC. then I write an app,this is my code:</p>
  
  <pre><code>package com.ashley.work;
  
  import android.os.Bundle;
  import android.app.Activity;
  import android.view.Menu;
  import android.view.MenuItem;
  import android.support.v4.app.NavUtils;
  import android.app.Activity;  
  import android.net.Uri;  
  import android.os.Bundle;  
  import android.view.View;  
  import android.widget.Button;  
  import android.widget.EditText;  
  import android.widget.VideoView;  
  
  
  public class TestPlayRTSP extends Activity {
  
  Button playButton ;  
  VideoView videoView ;  
  
  @Override
  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_test_play_rtsp);
  
      videoView = (VideoView)this.findViewById(R.id.myvideoview);  
  
      playButton = (Button)this.findViewById(R.id.button1);  
      playButton.setOnClickListener(new Button.OnClickListener(){  
      public void onClick(View v) {  
      PlayRtspStream("rtsp://140.xxx.xxx.xxx:8554/");  
      }  
      });  
  
  
  }
  
  private void PlayRtspStream(String rtspUrl){  
      videoView.setVideoURI(Uri.parse(rtspUrl));  
      videoView.requestFocus();  
      videoView.start();  
  }  
  
  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
      getMenuInflater().inflate(R.menu.activity_test_play_rtsp, menu);
      return true;
  }
  </code></pre>
  
  <p>}</p>
  
  <p>and I already set the permission. but this still can not play. nothing happend after I click the button. But if I replace the rtsp with other this two:</p>
  
  <ol>
  <li><p>rtsp://218.204.223.237:554/live/1/66251FC11353191F/e7ooqwcfbqjoo80j.sdp</p></li>
  <li><p>rtsp://v5.cache1.c.youtube.com/CjYLENy73wIaLQnhycnrJQ8qmRMYESARFEIJbXYtZ29vZ2xlSARSBXdhdGNoYPj_hYjnq6uUTQw=/0/0/0/video.3gp</p></li>
  </ol>
  
  <p>the app will play correctly. can any one tell me why? and is there any solution to play the VLC stream???</p>
  
  <p>thank you</p>
