Android VideoView repetition - android

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 seekTo 0 instead of specific position

I'm trying to start video from specific position but VideoView has strange behave. When I run code like that
videoView.seekTo(2000)
int current = videoView.getCurrentPosition()
Log.e("Current Time", String.valueOf(current))
Log gives me value 0. It should give 2000 because this is current position. Even If I implement onPreparedListener it doesn't worked (but in different way). It display proper value (2000) but video still is not seek.
videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp)
{
videoView.getDuration();
videoView.seekTo(2000);
Log.e("Current: ", String.valueOf(videoView.getCurrentPosition()));
}
});
How to fight this ? If I will build MediaPlayer + SurfaceView it will helps or will behave same as VideoView ?
Actually, the thing is,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, the standard VideoView does not support OnSeekCompleteListener.
But you can copy and locally customize the VideoView class to add this support yourself.
Or, You could try this
mVideoView.setOnPreparedListener(new MediaPlayer .OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.setOnSeekCompleteListener(new OnSeekCompleteListener() {
#Override
public void onSeekComplete(MediaPlayer mp) {
Log.e("Current: ", String.valueOf(videoView.getCurrentPosition()));
}
});
}
});
videoView.seekTo(2000); //or wherever the call is to be made
Hope this should help.

VideoView turn into black screen

I am developing multi player video app, so in that i created 9 views 3*3.
when i initialize all (3*3) videoview then working properly for few seconds and after some time video is goes to black screen, not show single video, i am not understand this issue is device oriented or android not supports more than 1 video in activity, anyone know how to resolve this issue, otherwise if video is turn into black then how to identify video is turned into black screen, if we found this then i will refresh view and again start video, i don't know it is correct way or not.
please anyone know about how to resolve this issue then please share information !
i use below code for show multiple video view in one activity
videoPlayer.setVideoPath("path");
videoPlayer.start();
videoPlayer.requestFocus();
videoPlayer.setKeepScreenOn(true);
set prepare listener
videoPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
}
set completion listener
videoPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
//play next
}
});
handle error listener
videoPlayer.setOnErrorListener(new MediaPlayer.OnErrorListener() {
#Override
public boolean onError(MediaPlayer mediaPlayer, int i, int i1) {
// play next
return true;
}
});
when video play next before that i set some propertied to mediaplyer object
mediaPlayer.setDisplay(null);
mediaPlayer.reset();
mediaPlayer.setDisplay(videoPlayer.getHolder());
i share basic code of my project, please tell me if anything is missing from me or android is not supported multiple videos in same activity.

MediaPlayer won't loop. setLooping() doesn't work

m_MediaPlayer = MediaPlayer.create(context, soundFromResource);
m_MediaPlayer.setVolume(0.99f, 0.99f);
m_MediaPlayer.setLooping(true);
m_MediaPlayer.setOnCompletionListener(USoundPlayback.this);
m_MediaPlayer.start();
I've tested it like above, I've also tested it by calling setLooping(true) after start() but with no luck.
I have two Nexus 5 phones, both with Android 5 on them. On one, the looping works, on the other the sound stops after one go, it won't loop.
Any ideas ?!
Apparently there's an issue with Android 5 devices which use the NuPlayer instead of the AwesomePlayer.
You can check it by going in the Developer Options, under the Media section there should be Use NuPlayer (experimental). I've unchecked that and it appears it's alright now.
I haven't been able to figure out how to fix this issue, so I've hacked it a bit. I've set some flags in the code and when it enters onCompletion, if the user hasn't specifically stopped the sound, i restart it there. If there's anyone with a better fix, let me know and i'll update this answer.
Here's the issue: https://code.google.com/p/android-developer-preview/issues/detail?id=1695
After a lot of experimentation with media player, I have found solution to this :
call
m_MediaPlayer.setLoopoing(true)
after
m_MediaPlayer.start()
It is an issue in media player.
I used the next code to fix that:
mMediaPlayer.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
if (looping) {
mMediaPlayer.seekTo(0);
}
}
});
I solve this using this workaround:
public static void setMpLooping(final MediaPlayer mp, final boolean isLooping) {
if (Build.VERSION.SDK_INT == Build.VERSION_CODES.LOLLIPOP
|| Build.VERSION.SDK_INT == Build.VERSION_CODES.LOLLIPOP_MR1) {
if (isLooping) {
mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp.start();
}
});
} else {
mp.setOnCompletionListener(null);
}
} else {
mp.setLooping(isLooping);
}
}
But remember, sometimes there is a delay during the transition from end to start of the track on Lollipop

Android mediacontroller Play Pause controls not refresh properly

I have used MediaController in my activity its working fine but when I play video for first time then there should b pause button visible but instead there is play and when I press that button then the video is paused correctly and state remains the same and after that its working properly. And same thing happens when Video Completed.
Is this a bug or I am doing any thing wrong?
videoView.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mediaController = new MediaController(VideoPlayerActivity.this){
public void hide(){
}
public void show(){
if(isPlayingAd){
super.hide();
}else{
super.show();
}
}
};
videoView.setMediaController(mediaController);
mediaController.setMediaPlayer(videoView);
mediaController.show();
}
});
I've been having the same issue. I was not calling MediaController.setVideoView as you were, as I thought VideoView.setMediaController was sufficient for wiring things up. I tried adding that, then moving the call to show within onPrepared, and now it is working.
I wish I had a better understanding; my best guess is that perhaps everything needs to be wired up properly before the media is prepared, and before calling show. In any case, here is what I have:
mMediaController = new MediaController(VideoPlayerActivity.this, false);
mVideoView.setOnPreparedListener( new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer pMp) {
mMediaController.show();
}
});
mVideoView.setMediaController(mMediaController);
mMediaController.setMediaPlayer(mVideoView);
mVideoView.setVideoPath(uri); // may not be applicable in your case
mVideoView.requestFocus();
mVideoView.start();
As Oneworld mentioned on the other answer, I had same issue with old Samsung devices. Even though MediaController wired with VideoView properly, play button loses its sync until pause and play again with MediaController.
This thing seems only happens on old Samsung devices(KitKat and below i guess).
The only solution I found was play video programmically by videoview.start() before showing controller by mc.show().

Mediaplayer error (-19,0) after repeated plays

I have a game in which a sound plays when a level is completed. Everything works fine to start with but after repeating a level 10 or 20 times the logcat suddenly reports:
"MediaPlayer error (-19,0)" and/or "MediaPlayer start called in state 0" and the sounds are no longer made.
I originally had the all sounds in mp3 format but, after reading that ogg may be more reliable, I converted them all to ogg, but the errors appeared just the same.
Any idea how I can fix this problem?
I was getting the same problem, I solved it by adding the following code to release the player:
mp1 = MediaPlayer.create(sound.this, R.raw.pan1);
mp1.start();
mp1.setOnCompletionListener(new OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
mp.release();
};
});
I think you are not releasing the mediaplayers you are using to play the sound..
You need to release() the media players otherwise the resources are not released , and you soon get out of memory (since you allocate them again next time). so,I think you can play twice or even thrice... but not many times without releasing the resources
MediaPlayer is not a good option when you are playing small sound effects as the user can click on multiple buttons very soon and you will have to create a MP object for all of them which doesnt happen synchronously. That is why you are not hearing sounds for every click. Go for the SoundPool Class which allows you to keep smaller sounds loaded in memory and you can play them any time you want without any lag which you would feel in a mediaplayer. http://developer.android.com/reference/android/media/SoundPool.html Here is a nice tutorial : http://www.anddev.org/using_soundpool_instead_of_mediaplayer-t3115.html
I solved both the errors (-19,0) and (-38,0) , by creating a new object of MediaPlayer every time before playing and releasing it after that.
Before :
void play(int resourceID) {
if (getActivity() != null) {
//Using the same object - Problem persists
player = MediaPlayer.create(getActivity(), resourceID);
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
player.release();
}
});
player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
}
}
After:
void play(int resourceID) {
if (getActivity() != null) {
//Problem Solved
//Creating new MediaPlayer object every time and releasing it after completion
final MediaPlayer player = MediaPlayer.create(getActivity(), resourceID);
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
player.release();
}
});
player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
}
}
This is a very old question, But this came up first in my search results So other people with the same issue will probably come upon this page eventually.
Unlike what some others have said, you can in fact use MediaPlayer for small sounds without using a lot of memory. I'll put in a little modified snippit from my soundboard app to show you what I'm getting at.
private MediaPlayer mp;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.your_layout);
mp = new MediaPlayer();
}
private void playSound(int soundID){
mp.reset();
AssetFileDescriptor sound = getResources().openRawResourceFd(soundID);
try {
mp.setDataSource(sound.getFileDescriptor(),sound.getStartOffset(),sound.getLength());
mp.prepare();
} catch (IOException e) {
e.printStackTrace();
}
mp.start();
}
with the way I set it up, you create on MediaPlayer object that you reuse everytime you play a sound so that you don't use up too much space.
You call .reset() instead of .release() because .release() is only used if you are disposing of an object, however you want to keep your MediaPlayer Object.
You use an assetfiledescriptor to set a new soundfile for your mediaplayer to play instead of setting a new object to your mediaplayer address because that way you are creating new objects within the method that aren't being handled properly and you will eventually run into the same error as you described.
This is only one of many ways to use MediaPlayer but I personally think it is the most efficient if you are only using it for small sound applications. The only issue with it is that it is relatively restrictive in what you can accomplish, but that shouldn't be much of an issue if you are indeed using it for small sound applications.
i try delete emulator and new create emulator for remove error of (-19,0) media player.
