VideoView Looping displays black screen after the first loop

I'm using VideoView to loop a small video, all works fine on the emulators, but when I deploy that to TV, after the first loop video turns black, but sound keeps going. This is the code:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layout);
VideoView videoview = (VideoView) findViewById(R.id.videoview1);
Uri uri = Uri.parse("android.resource://"+getPackageName()+"/"+R.raw.video);
videoview.setVideoURI(uri);
videoview.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.setLooping(true);
videoview.start();
}
});
}
The Emulator is using Android 6.0, the TV is Sony Bravia with Android 6.0.1.
I tested using SurfaceView, instead of VideoView - the same thing happens.
Any idea how to get rid of that black screen?
PS: There is a workaround that works - make OnCompletionListener and do videoview.start() there - this way it loops, but there's an ugly gap between the loops.

Just use this mVideoView.setZOrderOnTop(true); It will not show the black screen as the view appears.

Try to set your VideoView using handler like this.
videoview.setBackgroundColor(Color.WHITE); //color what you want as background
videoview.postDelayed(new Runnable() {
#Override
public void run() {
videoview.setVideoURI(videoUri);
}
}, 100);
videoview.postDelayed(new Runnable() {
#Override
public void run() {
vv.setBackgroundColor(Color.TRANSPARENT);
}
}, 300);
videoview.requestFocus();
videoview.start();
videoview.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { #Override
public void onPrepared(MediaPlayer mp) {
mp.setLooping(true);
}
});

I have looked into the source code of VideoView and the first thing that I would like to point out is that inside the setVideoURI() method the MediaPlayer object will be created, and the OnPreparedListener will be set.
Your mistake is that you set the OnPreparedListener after the MediaPlayer may already have prepared the video, thus never call the onPrepared in the listener you have set after that, which means the setLooping(true) was maybe never set on the MediaPlayer.
TL;DR:
Put videoview.setVideoURI(uri); after videoview.setOnPreparedListener().
videoview.start() should be after setVideoURI(). On finish it should start again without additional input because this time mp.setLooping(true); was correctly set and will be executed. No videoview.start() is necessary after the initial one.

I actually ended up using ExoPlayer instead of the default one.
It's a bit harder to set up, but this problem didn't show up there.

Android VideoView MediaPlayer OnInfoListener - events not fired

this following source code snippet is given:
videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mediaPlayer) {
mediaPlayer.setOnInfoListener(new MediaPlayer.OnInfoListener() {
#Override
public boolean onInfo(MediaPlayer mp, int what, int extra) {
if (what == MediaPlayer.MEDIA_INFO_BUFFERING_END){
activity.dismissDialog(DialogID.DIALOG_LOADING);
return true;
}
return false;
}
});
}
});
I am streaming HLS streams with Android 3.x+ devices and trying to hide a loading dialog once the buffering is completed.
The video streaming works, but the info events are never fired.
Any ideas?

I know its too late, But posting it for the users still seeking for the solution (This worked for me):
progressDialog.show();
videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mediaPlayer) {
mediaPlayer.setOnInfoListener(new MediaPlayer.OnInfoListener() {
#Override
public boolean onInfo(MediaPlayer mp, int what, int extra) {
if (what == MediaPlayer.MEDIA_INFO_BUFFERING_END){
progressDialog.dismiss();
return true;
} else if(what == MediaPlayer.MEDIA_INFO_BUFFERING_START){
progressDialog.show();
}
return false;
}
});
progressDialog.dismiss();
videoView.start();
}
});

You're right, the events are never fired. This is a known HLS bug that I don't think Google will fix.
This applies to the onInfo and the buffering events.
See https://code.google.com/p/android/issues/detail?id=42767 and https://code.google.com/p/googletv-issues/issues/detail?id=2
Sorry!

Not fully sure as to what the OP is asking, but here are some very untimely bits of information.
I wouldn't rely on onPrepared. I find it to be unreliable.
I have found the two most useful pieces of information for HLS streaming through the MediaPlayer are the duration of the video and the progress position of the video. You get both of these by listening to progress updates.
When the duration is greater than zero, you know the video is truly prepared and can be manipulate (scrub). When progress position changes, you know the video is done buffering and has commenced playback. This last item only works when the video is playing of course. The MediaPlayer tends to relay inaccurate information.
These pieces of information are mostly accurate and can usually be relied upon to be "fairly" timely. This timeliness varies from device to device.

onPrepared is called when the MediaPlayer is prepared to start buffering, not when the video is completely buffered. However, it is completely natural to dismiss the loading dialog from within the onPrepared method.
Also MEDIA_INFO_BUFFERING_END is used when MediaPlayer is resuming playback after filling buffers, so I do not think it should be something to use to dismiss the dialog. So this should work:
videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mediaPlayer) {
activity.dismissDialog(DialogID.DIALOG_LOADING);
}
});

You can able to set OnPreparedListener on videoView because its your object but if you checkout source of VideoView you will find that mMediaPlayer is its private member so any change that you do from external will not be applied to it.
As per your requirement you need buffering status so you can have thread or handler or some thing so you can update your UI to get buffer status there is one method
int percent = videoView.getBufferPercentage();
if(percent == 100){
// buffering done
}

You no need to go through setOnInfoListener
by overriding setOnPreparedListener method is enough. as in the api show
public void setOnPreparedListener (MediaPlayer.OnPreparedListener l)
Register a callback to be invoked when the media file is loaded and
ready to go.
so, you can dismiss your dialog inside setOnPreparedListener method is enough
like this
vv.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
handler.post(new Runnable() {
#Override
public void run() {
Toast.makeText(MainActivity.this, "finish11", Toast.LENGTH_LONG).show();
}
});
}
});

If you want to show loading each time it's buffering (initial time or subsequent buffer underruns) just ensure to show it again:
// at the beginning
show
boolean onInfo(int what, int extra) {
switch (what) {
case MEDIA_INFO_BUFFERING_END:
"hide";
break;
case MEDIA_INFO_BUFFERING_START
"show":
}
}
So this event sequence will do as desired:
- whenever you start (setVideoURI or start): show
- onPrepared: just plug the info listener
- onInfo BUFFERING_END hide (it's playing)
- onInfo BUFFERING_START show (it's buffering again)
- onInfo BUFFERING_END hide (it's playing)
Update:
This is assuming the info events work. Of course.

Android VideoView repetition

I have an application with a VideoView, in order to make the video play on a loop I use an onCompletionListner to call setVideoPath() again, like this:
mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer arg0) {
mVideoView.start();
}
});
mVideoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
//I have a log statment here, so I can see that it is making it this far.
mp.reset(); // <--- I added this recently to try to fix the problem
mVideoView.setVideoPath(file.getAbsolutePath());
}
});
This setup works well on all devices I've come across so far, I never had any trouble with it not repeating.
However the Motorola Xoom that I am testing on was recently upgraded to ICS. Now that it is on ICS this will work for a while and loop the video. But eventually (I've added a counter and some Logs, there does not appear to be any pattern to how many times it successfully loops before stopping) it will quit looping and just sit on a freeze frame of the first frame in the movie.
Does anyone know what could cause this not to loop properly any more? OR does anyone know of another way to get a VideoView to loop properly that does work under ICS still?

If you have only one video to play you can setLooping(true) in your on prepared listener.
myVideoView.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
// TODO Auto-generated method stub
mp.setLooping(true);
}
});
and you're done.

So far this:
mp.reset();
inside the onComplete callback seems to fix it. Would be very interested if anyone can explain what is going on with it.

VideoView not playing Video from desired position

i am using VideoView and seek bar but when i seekTo(..) on desired position through seekBar it play video from starting.
i trying this code:
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromTouch) {
mVideoView.seekTo(progress);
}

As Reno mentioned, you have to wait for the seeking to complete.
VideoView does not have a OnSeekCompleteListener() but you can access the MediaPlayer from the onPrepared method of the VideoView and then set the OnSeekCompleteListener, like this :
mVideoView.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.setOnSeekCompleteListener(new OnSeekCompleteListener() {
#Override
public void onSeekComplete(MediaPlayer mp) {
//TODO: Your code here
}
});
}
});

The call to VideoView.seekTo() is a wrapper around MediaPlayer.seekTo(). This function returns almost immediately even though the actual seeking is still being performed. Therefore you want to wait for seeking to complete via MediaPlayer.OnSeekCompleteListener.
However, as Reno mentioned, the standard VideoView does not support OnSeekCompleteListener.
But you can copy and locally customize the VideoView class to add this support yourself.
First, start with a copy of VideoView.java. Or you can clone the entire frameworks/base repo but warning it is over 1 gig of data to download.
Copy VideoView.java into your Eclipse Android project and it will start building but fail. Here's what I did to get it to compile:
Update the package statement to match your project.
Comment out the references to MetaData. The fix for this is on my todo list. These need to be replaced with calls to MediaMetadataRetriever.
Replace mContext with calls to getBaseContext()
Now you are ready to add the code for OnSeekCompleteListener. The implementation is similar to the other listeners, i.e OnCompletionListener.
public class VideoView extends SurfaceView
implements MediaPlayerControl {
// The client's listener which is the notification callback.
private OnSeekCompleteListener mOnSeekCompleteListener;
// Set up MediaPlayer to forward notifications to client.
private MediaPlayer.OnSeekCompleteListener mSeekCompleteListener =
new MediaPlayer.OnSeekCompleteListener() {
public void onSeekComplete(MediaPlayer mp) {
if (mOnCompletionListener != null) {
mOnCompletionListener.onCompletion(mMediaPlayer);
}
}
};
// API for client to set their listener.
public void setOnSeekCompleteListener(OnSeekCompleteListener l)
{
mOnSeekCompleteListener = l;
}
}
Finally, update your own code:
Update references to android.widget.VideoView to use your customized VideoView.
Implement a listener and set it via by calling setOnSeekCompleteListener().
Your code now receives notifications when the seek has really completed and it can then perform subsequent seeks.

You have to wait for the seeking to complete, unfortunately VideoView does not have a OnSeekCompleteListener() (why Google? -_-)

use my method works like charm
Take mediaPlayer
MediaPlayer mediaPlayer;
init mediaPlayer
videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mediaPlayer = mp;
}
});
use seekTo method like this
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
mediaPlayer.seekTo((int) mStartPosition, MediaPlayer.SEEK_CLOSEST);
} else {
mediaPlayer.seekTo((int) mStartPosition);
}

You should use
mVideoView.seekTo(progress, SEEK_CLOSEST)

Seamless video Loop with VideoView

I have the following code to take a video as a raw resource, start the video and loop it but I need the video to loop seamlessly as of now when it comes to an end of the clip and starts the clip again the transition between causes a flicker for a split second, which I really can't have for my app.
public class Example extends Activity {
VideoView vv;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
vv = (VideoView)findViewById(R.id.VideoView01);
//Video Loop
vv.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
vv.start(); //need to make transition seamless.
}
});
Uri uri = Uri.parse("android.resource://com.example/"
+ R.raw.video);
vv.setVideoURI(uri);
vv.requestFocus();
vv.start();
}
}
The clip is only 22 seconds long but was created to be seamless so it is possible to work without the delay.

Try this it will work 100%
VideoView videoView;<---write this in outside of method or else declare it as final variable.
videoView.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.setLooping(true);
}
});

In Kotlin simply use
videoView.setOnPreparedListener { it.isLooping = true }

Not sure if this helps years later, but I used
vv.start();
vv.setOnCompletionListener ( new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
vv.start();
}
});
and it has a seamless loop

The pause is for the underlying MediaPlayer to refresh its buffers. How long that will take will depend on a number of factors, many of which are outside your control (e.g., speed of CPU, speed of on-board flash storage).
One you can control is to get your video out of the resource and into the filesystem. Resources are stored in the APK, which is a ZIP file, so extracting the video this way probably takes extra time.
You may need to switch away from VideoView and use a SurfaceView with two MediaPlayers, alternating between them -- one is playing while the next is preparing, so when the playing one ends you can switch to the new player. I have not tried this, and so I do not know what the ramifications might be. However, I know that this technique is frequently used for audio playback to transition from one clip to another.

Little late, but any reason that you can't use the following?
MediaPlayer.setLooping(true);

If you are using Kotlin
videoView.setOnPreparedListener(object : MediaPlayer.OnPreparedListener {
override fun onPrepared(mp: MediaPlayer?) {
//Start Playback
videoView.start()
//Loop Video
mp!!.isLooping = true;
Log.i(TAG, "Video Started");
}
});
Using Arrow Expression short form
videoView.setOnPreparedListener { mp ->
//Start Playback
videoView.start()
//Loop Video
mp!!.isLooping = true;
Log.i(TAG, "Video Started");
};

Answer to this is to remove the audio from the video and convert that to a .ogg file which can be looped seamlessly and then use the video without audio to loop round and this works.

Here is answer friends, you must use vv.resume in setOnCompletionListener class
