问题
I have a VideoView which is used to play live stream. I am not able to find where the problem occurs.
In the beginning, I used RTMP to play the live stream using Vitamio which resulted in playing the audio leaving the screen blank. I checked out with the RTMP link, it works fine with a website. I surfed a lot about this, but I did not find any solution.
So now, I switched to HTTP to play the live stream which also results in the same problem (i.e audio playing fine but video is blank).
I am expecting a solution for either RTMP or HTTP.
Any Suggestions???
UPDATE 1: I have found a problem with the link. I used VLC Media Player to check whether my RTMP and HTTP link is working fine or not. The RTMP link works fine whereas the problem was with the HTTP link. The HTTP link plays only the audio.
On the other hand, having the RTMP link working fine, it doesn't solve the problem when using Vitamio. Any Suggestions for RTMP??
Here is my code:
public class ITVLiveStreamActivity extends Activity {
private VideoView liveVideoView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_itvlive_stream);
liveVideoView = (VideoView) findViewById(R.id.liveVideoView);
MediaController mediaController = new MediaController(this);
mediaController.setAnchorView(liveVideoView);
Uri uri = Uri.parse(getIntent().getStringExtra("rtmp://61.16.143.170:1935/live/7khh-8fhu-vxd3-8fuw"));
liveVideoView.setVideoURI(uri);
liveVideoView.setMediaController(mediaController);
liveVideoView.requestFocus();
liveVideoView.start();
}
}
UPDATE 2:
Here is my code using Vitamio:
import android.app.Activity;
import android.app.ProgressDialog;
import android.os.Bundle;
import io.vov.vitamio.LibsChecker;
import io.vov.vitamio.MediaPlayer;
import io.vov.vitamio.widget.MediaController;
import io.vov.vitamio.widget.VideoView;
public class ITVLiveStreamActivity extends Activity {
private String pathToFileOrUrl="rtmp://61.16.143.170:1935/live/7khh-8fhu-vxd3-8fuw";
private VideoView mVideoView;
private ProgressDialog progDailog;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if(!LibsChecker.checkVitamioLibs(this))
return;
setContentView(R.layout.activity_itvlive_stream);
mVideoView = (VideoView)findViewById(R.id.vitamio_videoView);
progDailog = new ProgressDialog(this);
progDailog.setCancelable(false);
progDailog.setMessage(getResources().getString(R.string.loading));
progDailog.show();
mVideoView.setVideoPath(pathToFileOrUrl);
mVideoView.setMediaController(new MediaController(this));
mVideoView.requestFocus();
mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mediaPlayer) {
progDailog.dismiss();
mediaPlayer.setPlaybackSpeed(1.0f);
}
});
}
}
I am getting the same result (i.e) Audio is playing but video is blank.
Here I have added the screenshot

You can create an activity like this to open default Video View
public class VideoViewActivity extends Activity {
// Declare variables
ProgressDialog pDialog;
VideoView videoview;
// Insert your Video URL
// String VideoURL; /*= "http://www.androidbegin.com/tutorial/AndroidCommercial.3gp";*/
String VideoURL;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get the layout from video_main.xml
setContentView(R.layout.video_view);
// Find your VideoView in your video_main.xml layout
videoview = (VideoView) findViewById(R.id.VideoView);
// Execute StreamVideo AsyncTask
VideoURL = getIntent().getExtras().getString(Constants.LINK);
// Log.v("video", VideoURL);
// Create a progressbar
pDialog = new ProgressDialog(VideoViewActivity.this);
// Set progressbar title
//pDialog.setTitle("Android Video Streaming Tutorial");
// Set progressbar message
pDialog.setMessage("Buffering...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
// Show progressbar
pDialog.show();
try {
// Start the MediaController
MediaController mediacontroller = new MediaController(
VideoViewActivity.this);
mediacontroller.setAnchorView(videoview);
// Get the URL from String VideoURL
Uri video = Uri.parse(VideoURL);
videoview.setMediaController(mediacontroller);
videoview.setVideoURI(video);
} catch (Exception e) {
// Log.e("Error", e.getMessage());
pDialog.dismiss();
e.printStackTrace();
} finally {
videoview.setOnErrorListener(new OnErrorListener() {
@Override
public boolean onError(MediaPlayer mp, int what, int extra) {
CommonUtilities.showToast(VideoViewActivity.this, "Video Format not supported by device.");
VideoViewActivity.this.finish();
return true;
}
});
}
videoview.requestFocus();
videoview.setOnPreparedListener(new OnPreparedListener() {
// Close the progress bar and play the video
public void onPrepared(MediaPlayer mp) {
pDialog.dismiss();
videoview.start();
}
});
}
}

Edited Answer
I have tested streaming on vitamio library demo sample and its working fine.
public class VideoViewDemo extends Activity {
private VideoView mVideoView;
private String pathToFileOrUrl ="rtmp://61.16.143.170:1935/live/7khh-8fhu-vxd3-8fuw";
private ProgressDialog progDailog;
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
if (!LibsChecker.checkVitamioLibs(this))
return;
setContentView(R.layout.videoview);
mVideoView = (VideoView) findViewById(R.id.surface_view);
progDailog = new ProgressDialog(this);
progDailog.setCancelable(false);
progDailog.setMessage("Please wait");
progDailog.show();
mVideoView.setVideoPath(pathToFileOrUrl);
mVideoView.setMediaController(new MediaController(this));
mVideoView.requestFocus();
mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mediaPlayer) {
progDailog.dismiss();
mediaPlayer.setPlaybackSpeed(1.0f);
}
});
}
}
and xml layout,
<io.vov.vitamio.widget.VideoView
android:id="@+id/surface_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
Now i'm sure code work well.
Thanks hope this will help you .
