How to prepare mediaplayer in android while another playing?

How to prepare mediaplayer in android while another playing? - android

I using MediaPlayerto play video from http stream is any solution to prepare second media player with another http url while first one still playing?
I want to play two videos without black screen between them, when first one end second start immediately.
Here is my code:
public class VideoActivity extends Activity implements SurfaceHolder.Callback {
private MediaPlayer mediaPlayer;
private SurfaceHolder surfaceHolder;
private SurfaceView playerSurfaceView;
private String videoSrc = "http://192.168.1.101:8090/api/video/";
private String android_id;
private MediaPlayer next;
private static boolean firstCall = true;
private String secondVideoSrc = "http://192.168.1.101:8090/api/secondvideo/";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_video);
playerSurfaceView = (SurfaceView)findViewById(R.id.playersurface);
surfaceHolder = playerSurfaceView.getHolder();
surfaceHolder.addCallback(this);
GetDeviceId();
videoSrc += android_id;
secondVideoSrc += android_id;
}
#Override
public void surfaceCreated(SurfaceHolder holder) {
prepareVideoPlayer();
}
#Override
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
}
#Override
public void surfaceDestroyed(SurfaceHolder holder) {
}
private void GetDeviceId() {
android_id = Settings.Secure.getString(getBaseContext().getContentResolver(),
Settings.Secure.ANDROID_ID);
}
private void prepareVideoPlayer() {
try {
mediaPlayer = new MediaPlayer();
mediaPlayer.setDisplay(surfaceHolder);
mediaPlayer.setDataSource(this, Uri.parse(videoSrc));
mediaPlayer.setScreenOnWhilePlaying(true);
mediaPlayer.prepareAsync();
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
if(firstCall) {
mediaPlayer.start();
firstCall = false;
}
new AsyncPrepareNext().execute();
}
});
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
next.start();
}
});
}
catch(Exception ex) {
}
}
private void prepareNext() {
try {
next = new MediaPlayer();
next.setDisplay(surfaceHolder);
next.setDataSource(this, Uri.parse(secondVideoSrc));
next.setScreenOnWhilePlaying(true);
next.prepareAsync();
next.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
}
});
next.setAudioStreamType(AudioManager.STREAM_MUSIC);
next.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
}
});
}
catch(Exception ex) {
}
}
private class AsyncPrepareNext extends AsyncTask<Void,Void,Void> {
#Override
protected Void doInBackground(Void... params) {
prepareNext();
return null;
}
}
}
When i run this first video starts for 2 or 3 seconds and then stop with some errors like media server died, audio flinger died, error (100,0), error (38,0)

You'll probably need to implement the OnPreparedListener() and OnCompletedListener() to accomplish this and you might need 2 media players for it as well.
#Override
public void onPrepared(MediaPlayer mp){
// Set Video Source for second video
mp.setDataSource(path);
// Prepare second video
mp.prepareAsync();
}
#Override
public void onCompletion(MediaPlayer mp){
// Start second video here
mp.start();
}
and set them like this:
mediaPlayer.setOnPreparedListener(new OnPreparedListener());
mediaPlayer.setOnCompletedListener(new OnCompletionListener());

Android MediaPlayer with SurfaceView Fails on Prepare() Method

I am trying to build a video player using surface view and media player. My data source is an online video and I have enabled internet permission in manifest.
However, the video does not pay but throws a warning about prepare method without any hint at what the problem is like below:
W/System.err: at android.media.MediaPlayer._prepare(Native Method)
at android.media.MediaPlayer.prepare(MediaPlayer.java:1188)
at in.sashi.androidvideoplayer.MainActivity.surfaceCreated(MainActivity.java:64)
here's my code for this purpose:
public class MainActivity extends AppCompatActivity implements SurfaceHolder.Callback, MediaPlayer.OnPreparedListener, View.OnClickListener {
private static final String TAG = MainActivity.class.getSimpleName();
private SurfaceView surfaceView;
private ImageView playIV, backIV;
private TextView videoNameTV;
private MediaPlayer mediaPlayer;
private SurfaceHolder holder;
// private static final String VIDEO_URL = "https://www.youtube.com/watch?v=vEVd0QMjCc8";
private static final String VIDEO_URL = "http://mic.duytan.edu.vn:83/FINAL.mp4";
private static final String VIDEO_NAME = "FALL HARDER | BASKETBALL MOTIVATION";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
init();
}
private void init() {
surfaceView = findViewById(R.id.surfsceView);
playIV = findViewById(R.id.playIV);
backIV = findViewById(R.id.backIV);
videoNameTV = findViewById(R.id.videoNameTV);
videoNameTV.setText(VIDEO_NAME);
backIV.setOnClickListener(this);
playIV.setOnClickListener(this);
holder = surfaceView.getHolder();
holder.addCallback(this);
surfaceView.setKeepScreenOn(true);
mediaPlayer = new MediaPlayer();
}
#Override
public void surfaceCreated(SurfaceHolder holder) {
mediaPlayer.setDisplay(holder);
try {
mediaPlayer.setDataSource(VIDEO_URL);
mediaPlayer.prepare();
mediaPlayer.setOnPreparedListener(this);
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
} catch (IOException e) {
e.printStackTrace();
}
}
#Override
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
}
#Override
public void surfaceDestroyed(SurfaceHolder holder) {
}
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
#Override
public void onClick(View v) {
switch (v.getId()){
case R.id.backIV:
onBackPressed();
break;
case R.id.playIV:
if (mediaPlayer.isPlaying()){
Log.d(TAG, "Pause Clicked");
mediaPlayer.pause();
playIV.setImageResource(R.drawable.play);
} else {
Log.d(TAG, "Play Clicked");
mediaPlayer.start();
playIV.setImageResource(R.drawable.pause);
}
break;
}
}
#Override
protected void onPause() {
super.onPause();
collect();
}
private void collect() {
if (mediaPlayer != null){
mediaPlayer.release();
mediaPlayer = null;
}
}
}
Can anyone help me to figure this out? Thanks.

Use mediaplayer object which is being defined globally.
#Override
public void onPrepared(MediaPlayer mp) {
mediaPlayer.start();
}

How about this?
#Override
public void surfaceCreated(SurfaceHolder holder) {
mediaPlayer.setDisplay(holder);
try {
mediaPlayer.setDataSource(VIDEO_URL);
mediaPlayer.setOnPreparedListener(this);
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.prepareAsync();
} catch (IOException e) {
e.printStackTrace();
}
}

video playback Issue using Cameraview

I am capturing a video using Cameraview, once the recording is finished, the app will playback the video in fullscreen. However after I record the first video, I am only seeing a black screen. If I ress back and record another video everything works and the playback is successful. The errors I am having are:
E/MediaPlayer: error (1, -2147483648)
E/MediaPlayer: isPlaying: called in state MEDIA_PLAYER_STATE_ERROR
here is the code sample:
public class VideoPreviewActivity extends AppCompatActivity {
FullscreenVideoLayout videoLayout;
CustomReusingDialog mCustomReusingDialog;
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_video_preview);
videoLayout = (FullscreenVideoLayout) findViewById(R.id.videoview);
videoLayout.setActivity(this);
final Uri videoUri = getIntent().getParcelableExtra("video");
try {
videoLayout.setVideoURI(videoUri);
} catch (IOException e) {
e.printStackTrace();
}
videoLayout.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
playVideo();
}
});
videoLayout.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
mCustomReusingDialog =CustomReusingDialog.newInstance(new CustomReusingDialog.Builder(VideoPreviewActivity.this, new CustomReusingDialog.OnDialogShowListener() {
#Override
public void onGetDialog(final Dialog mDialog, View mView) {
TextView uploadText =(TextView)mView.findViewById(R.id.uploadText);
TextView deleteText =(TextView)mView.findViewById(R.id.deleteText);
uploadText.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mCustomReusingDialog.dismiss();
if (LoginManager.isNetworkAvailable(getApplicationContext()))
new UploadManager(VideoPreviewActivity.this,new File(videoUri.getPath())).execute();
else

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.

MediaController play button not updating when song is playing

I am trying to use the mediacontroller to play audio. I am able to get the audio working but when the song starts playing the play button on my mediacontroller does not update. If press the play button on the mediacontroller it pauses the song and seeks the progressbar. Then if i press pause it plays the song again. i am calling
mp.start()
does this not update the play button. How can I get the button to change to the pause button when I call start?
public class QuickMusicPlayer implements MediaController.MediaPlayerControl {
private final MediaPlayer mMediaPlayer;
private final MediaController mMediaController;
private Activity mActivity;
public QuickMusicPlayer(View anchorView, Activity activity) {
mActivity = activity;
mMediaPlayer = new MediaPlayer();
mMediaController = new MediaController(activity);
mMediaController.setMediaPlayer(this);
mMediaController.setAnchorView(anchorView);
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
}
public void setUrl(String url) {
mMediaPlayer.reset();
if (TextUtils.isEmpty(url)) {
ViewUtil.showCroutonAlert(mActivity, R.string.cant_play_music);
} else {
try {
mMediaPlayer.setDataSource(url);
mMediaPlayer.prepareAsync();
mMediaController.setEnabled(true);
mMediaController.show(0);
} catch (IOException e) {
e.printStackTrace();
}
}
}
#Override
public void start() {
mMediaPlayer.start();
}
#Override
public void pause() {
mMediaPlayer.pause();
}
#Override
public int getDuration() {
return mMediaPlayer.getDuration();
}
#Override
public int getCurrentPosition() {
return mMediaPlayer.getCurrentPosition();
}
#Override
public void seekTo(int pos) {
mMediaPlayer.seekTo(pos);
}
#Override
public boolean isPlaying() {
return mMediaPlayer.isPlaying();
}
#Override
public int getBufferPercentage() {
return 0;
}
#Override
public boolean canPause() {
return true;
}
#Override
public boolean canSeekBackward() {
return true;
}
#Override
public boolean canSeekForward() {
return true;
}
#Override
public int getAudioSessionId() {
return 0;
}
}

Figured it out. I need to call show again after start to update the buttons
mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
mMediaController.show(0);
}
});

Live audio stuttering in mediaplayer()?

I am new to android. I am making a live audio streaming app(streams from a URL). As soon as I hit play, the audio plays but there is a stuttering about every half second. I checked the live audio URL on my computer and it plays perfectly. And I checked it in another audio streaming app I am making, using the same emulator, and it plays perfectly there too. The streaming file is .mp3. I have added the code.
public class StreamAudioFromUrlSampleActivity extends Activity implements OnClickListener, OnTouchListener, OnCompletionListener, OnBufferingUpdateListener{
private Button btn_play,
btn_pause,
btn_stop;
//private SeekBar seekBar;
private MediaPlayer mediaPlayer;
private int lengt
hOfAudio;
private final String URL = "**some url**";
//private final Handler handler = new Handler();
/*private final Runnable r = new Runnable() {
#Override
public void run() {
//updateSeekProgress();
}
};*/
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
init();mediaPlayer = new MediaPlayer();
}
private void init() {
btn_play = (Button)findViewById(R.id.btn_play);
btn_play.setOnClickListener(this);
btn_pause = (Button)findViewById(R.id.btn_pause);
btn_pause.setOnClickListener(this);
btn_pause.setEnabled(false);
btn_stop = (Button)findViewById(R.id.btn_stop);
btn_stop.setOnClickListener(this);
btn_stop.setEnabled(false);
//seekBar = (SeekBar)findViewById(R.id.seekBar);
//seekBar.setOnTouchListener(this);
//mediaPlayer.setOnBufferingUpdateListener(this);
//mediaPlayer.setOnCompletionListener(this);
}
#Override
public void onBufferingUpdate(MediaPlayer mediaPlayer, int percent) {
//seekBar.setSecondaryProgress(percent);
}
#Override
public void onCompletion(MediaPlayer mp) {
btn_play.setEnabled(true);
btn_pause.setEnabled(false);
btn_stop.setEnabled(false);
}
#Override
public boolean onTouch(View v, MotionEvent event) {
if (mediaPlayer.isPlaying()) {
//SeekBar tmpSeekBar = (SeekBar)v;
//mediaPlayer.seekTo((lengthOfAudio / 100) * tmpSeekBar.getProgress() );
}
return false;
}
#Override
public void onClick(View view) {
try {
mediaPlayer.setDataSource(URL);
mediaPlayer.prepare();
//lengthOfAudio = mediaPlayer.getDuration();
} catch (Exception e) {
