android media player stops playing after some minutes

I have an issue with Media player always stopping randomly after some few mins, most times, when the phone sleeps and you touch it again, the video hangs and stops playing.
I have tried many solutions here on stackoverflow, none worked. I'm almost pulling my hair out !!!
I've tried this answer
Android MediaPlayer stops playing after some time
MediaPlayer randomly stops on Android 4.4 (19)
How to prevent mediaplayer to stop when screen goes off?
and many more answers, they all didn't work
This is my code below
public class MainActivity {
MediaPlayer mp;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mp = MediaPlayer.create(this, R.raw.my_webm_video);
mp.setWakeMode(getApplicationContext(), PowerManager.PARTIAL_WAKE_LOCK);
playVideo();
}
#Override
public void onResume() {
super.onResume();
mp = MediaPlayer.create(this, R.raw.my_webm_video);
mp.setWakeMode(getApplicationContext(), PowerManager.PARTIAL_WAKE_LOCK);
playVideo();
}
public void playVideo(){
SurfaceView sv = (SurfaceView) findViewById(R.id.surfaceView);
SurfaceHolder holder = sv.getHolder();
holder.addCallback(new SurfaceHolder.Callback(){
#Override
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) { }
#Override
public void surfaceCreated(SurfaceHolder holder) {
mp.setDisplay(holder);
mp.start();
mp.setLooping(true);
}
#Override
public void surfaceDestroyed(SurfaceHolder holder) {
}
});
}
}
This is my XML layout
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<SurfaceView
android:id="#+id/surfaceView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>

ok, so i finally solved the problem. Incase any one else run into this issue
in onCreate i checked if the video was already playing, to make sure it isn't called to re-play each time.
int firstPlayed = 0;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mp = MediaPlayer.create(this, R.raw.my_webm_video);
mp.setWakeMode(getApplicationContext(), PowerManager.PARTIAL_WAKE_LOCK);
if(!mp.isPlaying()) {
firstPlayed = 1;
playVideo();
}
}
I checked in onResume incase the user navigates out of the activity and goes back, Which makes the video screen turn black.
public void onResume() {
super.onResume();
if(!mp.isPlaying() && firstPlayed == 0) {
mp = MediaPlayer.create(this, R.raw.my_webm_video);
mp.setWakeMode(getApplicationContext(), PowerManager.PARTIAL_WAKE_LOCK);
playVideo();
}
firstPlayed = 0;
}
And then i noticed that i needed a firstPlayed check to be sure.

MediaPlayer doesn't resume video after activity restart

I have a MediaPlayer object that uses a SurfaceHolder object as a surface. There is a button on top of the video that takes me out of the video to a website. When that happens, I pause the player with player.pause(). When I return from the website, I resume the player with player.start(). I know that the surface gets destroyed when the activity is not displayed anymore, and it gets recreated as soon as the activity is restarted. In my surfaceCreated(), I set the surface for the player again (since it no longer has a surface at that point), and then resume. However, the player simply restarts the video from the beginning.
I've tried commenting out the line that takes me to the website, just to see if pause/start works properly and resumes from last spot. It does. I'm not sure why this behaviour doesn't happen when I leave and re-enter the video activity though.
I also tried using the player.seekTo() call. There was no difference. In fact, when I disabled the button taking me to a site to just pausing the video, with the seekTo() call the video ALSO started from the beginning despite position being not 0.
The player object is the same all the way throughout.
Just because the surface is a new one on restart, it doesn't know or care of its contents, does it? The player should be managing that, right?
I'm out of ideas at this point. Can anyone please offer any tips?
UPDATE: So I threw together a quick app just to eliminate any other external factors. Here's the full code for the video class (other class is just an activity with a play button):
public class VideoPlayer extends Activity implements MediaPlayer.OnCompletionListener,
MediaPlayer.OnErrorListener, MediaPlayer.OnPreparedListener, MediaPlayer.OnSeekCompleteListener, MediaPlayer.OnVideoSizeChangedListener,
SurfaceHolder.Callback {
private MediaPlayer player;
private SurfaceHolder mSurfaceHolder;
private SurfaceView mSurfaceView;
private Button leaveVideoButton;
private boolean isPaused = false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.video_layout);
leaveVideoButton = (Button) findViewById(R.id.go_to_web);
leaveVideoButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Uri uri = Uri.parse("http://www.google.com");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
pauseSteps();
startActivity(intent);
}
});
createPlayer();
createSurface();
}
private void createSurface() {
mSurfaceView = (SurfaceView) findViewById(R.id.surface);
mSurfaceHolder = mSurfaceView.getHolder();
mSurfaceHolder.addCallback(this);
mSurfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
}
private void createPlayer() {
player = new MediaPlayer();
player.setOnCompletionListener(this);
player.setOnErrorListener(this);
player.setOnPreparedListener(this);
player.setOnVideoSizeChangedListener(this);
player.setOnSeekCompleteListener(this);
}
private void pauseSteps() {
if(player.isPlaying()) {
player.pause();
isPaused = true;
}
}
private void playSteps() {
if(isPaused) {
isPaused = false;
player.start();
}
}
#Override
protected void onDestroy() {
super.onDestroy();
if (player.isPlaying()) {
player.stop();
}
player.reset();
player.release();
player = null;
}
#Override
public void surfaceCreated(SurfaceHolder holder) {
player.setDisplay(holder);
if (!isPaused) {
try {
// player.setDataSource(path);
AssetFileDescriptor afd = getResources().openRawResourceFd(R.raw.video);
if (afd == null) return;
player.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
afd.close();
player.prepare();
} catch (IOException e) {
e.printStackTrace();
}
} else {
playSteps();
}
}
#Override
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
}
#Override
public void surfaceDestroyed(SurfaceHolder holder) {
}
#Override
public void onCompletion(MediaPlayer mp) {
}
#Override
public boolean onError(MediaPlayer mp, int what, int extra) {
return false;
}
#Override
public void onPrepared(MediaPlayer mp) {
player.start();
}
#Override
public void onSeekComplete(MediaPlayer mp) {
}
#Override
public void onVideoSizeChanged(MediaPlayer mp, int width, int height) {
}
}
UPDATE 2: So I tried a different video and it resumed just fine from the same spot. This must be some encoding issue.

Playing YouTube Videos using mediaplayer of eclipse

There are many controls to play youtube videos in eclipse like WebView, YouTubePlayerView, VideoView etc.
My doubt is can we play it using media player? Found that, url having extension like .mp4 can play using media player. But when tried with youtube video url it shows an error Start Called in state 0 .
if(isYTFlag){ //if youtube url
mediaPlayer.setDataSource(videoURL);
}
else{ //local mp4
afd = this.getResources().openRawResourceFd(Integer.parseInt(videoURL));
mediaPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getDeclaredLength());
}
Please help to verify

Here is another working code
MainActivity.java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_video_view);
VideoView videoView =(VideoView)findViewById(R.id.videoView);
MediaController mediaController= new MediaController(this);
mediaController.setAnchorView(videoView);
Uri uri=Uri.parse("rtsp://r2---sn-a5m7zu76.c.youtube.com/

videoView.setMediaController(mediaController);
videoView.setVideoURI(uri);
videoView.requestFocus();
videoView.start();}

You can play the video using media player easily like below.
Player.java file
public class Player extends Activity implements SurfaceHolder.Callback,
OnPreparedListener {
private MediaPlayer mediaPlayer;
private SurfaceHolder vidHolder;
private SurfaceView vidSurface;
String vidAddress = "https://archive.org/download/ksnn_compilation_master_the_internet/ksnn_compilation_master_the_internet_512kb.mp4";
String videoSrc = "http://bffmedia.com/bigbunny.mp4";
String videoToPlay = "rtsp://v6.cache1.c.youtube.com/CjYLENy73wIaLQkDsLHya4-Z9hMYDSANFEIJbXYtZ29vZ2xlSARSBXdhdGNoYKX4k4uBjbOiUQw=/0/0/0/video.3gp";
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.mediaplayer);
vidSurface = (SurfaceView) findViewById(R.id.surfView);
vidHolder = vidSurface.getHolder();
vidHolder.addCallback(this);
}
#Override
public void onPrepared(MediaPlayer mp) {
// TODO Auto-generated method stub
mediaPlayer.start();
}
#Override
public void surfaceCreated(SurfaceHolder holder) {
// TODO Auto-generated method stub
try {
mediaPlayer = new MediaPlayer();
mediaPlayer.setDisplay(vidHolder);
mediaPlayer.setDataSource(videoToPlay);
mediaPlayer.prepare();
mediaPlayer.setOnPreparedListener(this);
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
} catch (Exception e) {
e.printStackTrace();
}
}
#Override
public void surfaceChanged(SurfaceHolder holder, int format, int width,
int height) {
// TODO Auto-generated method stub
}
#Override
public void surfaceDestroyed(SurfaceHolder holder) {
// TODO Auto-generated method stub
}
}
//mediaplayer.xml file
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#000000"
android:paddingBottom="10dp" >
<SurfaceView
android:id="#+id/surfView"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</RelativeLayout>
//finally add internet permission in manifest.xml file
<uses-permission android:name="android.permission.INTERNET" />

Have you tried this?
btnPlay.setOnClickListener(new OnClickListener() {public void onClick(View v) {
startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse("https://www.youtube.com/watch?v=jHHn52KhBkQ")));
}}});
In this solution you can directly pass the youtube video url to the Intent which we want to play into media player.
For playing video try this link Playing(Streaming) video with MediaPlayer
Use your videoUrl instead of their 3gp video url.

Mediaplayer sometimes doesn't work

I'm running into the problem when I my play a video with my app using mediaplayer. Sometimes the video will play fine but other times there will just be a black screen. Its not the file that I'm calling the video from because I've tested on the same file and it works sometimes and sometimes doesn't. I feel this problem most commonly occurs after I have played a couple of videos. I usually get away with playing 3-4 before the problem starts. I was wondering what caused this and how I could fix it. My code is posted below.
public class FullImageActivity extends Activity implements SurfaceHolder.Callback, OnPreparedListener, OnErrorListener{
private static final String TAG = null;
MediaPlayer player;
SurfaceView surfaceview;
SurfaceHolder surfaceHolder;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.full_image);
Intent i = getIntent();
long id = i.getExtras().getLong("id");
String path = i.getExtras().getString("videopath");
surfaceview = (SurfaceView)findViewById(R.id.surfaceview);
surfaceHolder = surfaceview.getHolder();
surfaceHolder.addCallback(this);
player = new MediaPlayer();
try {
player.reset();
player.setOnErrorListener(this);
player.setDataSource(path);
player.setOnPreparedListener(this);
player.prepare();
player.start();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (SecurityException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
#Override
public void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2, int arg3) {
// TODO Auto-generated method stub
}
#Override
public void surfaceCreated(SurfaceHolder holder) {
player.setDisplay(holder);
}
#Override
public void surfaceDestroyed(SurfaceHolder arg0) {
// TODO Auto-generated method stub
}
#Override
public void onPrepared(MediaPlayer p) {
}
#Override
public boolean onError(MediaPlayer arg0, int arg1, int arg2) {
Log.i(TAG, "THERE WAS AN ERROR");
return false;
}
Thanks.

It's difficult to know exactly what the problem is.
A couple of things to try:
Make sure you are calling .release() in onPause(). This just ensures resources are released appropriately. You will need to reset things in onResume(), etc.
http://developer.android.com/reference/android/media/MediaPlayer.html#release()
Unless you really need to manipulate the surface, consider using a VideoView. It's not as fully featured as the MediaPlayer object but takes away some of the hassle of dealing with a SurfaceView, and manages the state for you.
http://developer.android.com/reference/android/widget/VideoView.html

The problem is, that your implementation relies on the assumption, that the activity gets destroyed, when the media player finished.
Yet it is possible, that your activity already exists, when your intent is fired up. In that case, your application skips onCreate(), so the media player can't be initialised.
You should override the onStart() method to launch the media player.

Android SDK: Media Player - Load video stream from HTTP url

I have a MediaPlayerActivity with the following code:
This code basically tries to get a video stream from a http url and load it but for some reason it keeps crashing.
public class MediaPlayerActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.video_player);
SurfaceView v = (SurfaceView) findViewById(R.id.surface_video);
SurfaceHolder holder = v.getHolder();
holder.setFixedSize(400,300);
MediaPlayer mp = MediaPlayer.create(this, Uri.parse("http://stream-url.com/playlist.m3u8"));
mp.setDisplay(holder);
//mp.setAudioStreamType(2);
try {
//mp.prepare();
mp.start();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
video_player.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<SurfaceView android:id="#+id/surface_video"
android:layout_width="250px"
android:layout_height="250px">
</SurfaceView>
<LinearLayout
android:orientation="horizontal"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:padding="10dip"
>
</LinearLayout>
</LinearLayout>
When I go to this activity using the following code it crashes:
Intent myIntent = new Intent(HomeActivity.this, MediaPlayerActivity.class);
HomeActivity.this.startActivity(myIntent);
What am I doing wrong?

Without logs, two suggestions:
try implementing SurfaceHolder.Callback.surfaceCreated().
try using MediaPlayer.create() that accepts SurfaceHolder
Details of (1)
Maybe your surface is not yet created when you call start(). You should use MediaPlayer.setDisplay() and MediaPlayer.start() only after surface is created. To do this, you should add overrideSurfaceHolder.Callback.surfaceCreated()`. For example, your code could look like this.
public class MediaPlayerActivity extends Activity implements SurfaceHolder.Callback {
MediaPlayer mp;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.video_player);
SurfaceView v = (SurfaceView) findViewById(R.id.surface_video);
SurfaceHolder holder = v.getHolder();
holder.setFixedSize(400,300);
holder.addCallback(this).
mp = MediaPlayer.create(this, Uri.parse("http://stream-url.com/playlist.m3u8"));
#Override
public void surfaceCreated(SurfaceHolder holder) {
mp.setDisplay(holder);
try {
mp.start();
} catch (IllegalStateException e) {
e.printStackTrace();
}
}
}
Details of (2)
There seems to be other MediaPlayer.create() that accepts SurfaceHolder as one of the arguments - you could try it: http://developer.android.com/reference/android/media/MediaPlayer.html#create(android.content.Context, android.net.Uri, android.view.SurfaceHolder)
