JavaFX MediaPlayer - Music stops after 10 seconds - java

Here's the code, like the title says the music stops after 10ish seconds, i played the file normally in vlc or other programs, it lasts more than 5 minutes.
public void music(){
String bip = "src/data/fjordmusic.mp3";
Media hit = new Media(Paths.get(bip).toUri().toString());
MediaPlayer mediaPlayer = new MediaPlayer(hit);
mediaPlayer.play();
}

Your question was already asked and answered here:
MediaPlayer stop playing after about 5 seconds
It seems that the garbage collector ereases the MediaPlayer instance after finishing the method. Put the declaration of MediaPlayer above the method and it should work.
MediaPlayer mediaPlayer
public void music(){
String bip = "src/data/fjordmusic.mp3";
Media hit = new Media(Paths.get(bip).toUri().toString());
mediaPlayer = new MediaPlayer(hit);
mediaPlayer.play();
}
(I'm not able to post comments, so I'm forced to write an answer.)

Try AudioClip instead:
javafx.scene.media.AudioClip;
public void music(){
String bip = "src/data/fjordmusic.mp3";
Media hit = new Media(Paths.get(bip).toUri().toString());
AudioClip mediaPlayer = new AudioClip(hit.getSource());
mediaPlayer.play();
}

Android Studio Mediaplayer

I am a completely begginer guy in Android Studio and mobile apps in general. I used to create websites on Wordpress and i don't have so much experience on coding. Recently i started experimenting with mobile apps and mostly Android Studio. I bought a template for a Logo Quiz game and i managed to make it run without errors and publish it in Play Store as my first game. The player can see a part of the logo and guess the brand name using the given letters
But i would like to use the same template with new graphics and create a music quiz.
Instead of the logo guess game, the player will be able to listen a part of a song and guess the song's title.
The current project is getting the file names from a database stored in assets/databases folder.
So i managed to add start, pause and stop buttons in my activity_play.xml and succesfully created a mediaplayer in activityPlay.java file like:
public void music(View view) {
switch (view.getId()){
case R.id.button:
// Check if mediaPlayer is null. If true, we'll instantiate the MediaPlayer object
if(mediaPlayer == null){
mediaPlayer = MediaPlayer.create(this, R.raw.music);
}
// Then, register OnCompletionListener that calls a user supplied callback method onCompletion() when
// looping mode was set to false to indicate playback is completed.
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
// Here, call a method to release the MediaPlayer object and to set it to null.
stopMusic();
}
});
// Next, call start() method on mediaPlayer to start playing the music.
mediaPlayer.start();
break;
case R.id.button2:
if(mediaPlayer != null) {
// Here, call pause() method on mediaPlayer to pause the music.
mediaPlayer.pause();
}
break;
case R.id.button3:
if(mediaPlayer != null){
// Here, call stop() method on mediaPlayer to stop the music.
mediaPlayer.stop();
// Call stopMusic() method
stopMusic();
}
break;
}
}
private void stopMusic() {
mediaPlayer.release();
mediaPlayer = null;
}
// Call stopMusic() in onStop() overridden method as well.
#Override
protected void onStop() {
super.onStop();
stopMusic();
}
The above code can succesfully play the music.mp3 file located in raw folder. The app i bought is using the following code to load the images and display them for each level:
String image_a = listDataBase.get(1);
String image_q = listDataBase.get(2);
if (isTrue == 1) {
String imgPath;
if (numImage == 0) {
imgPath = "file:///android_asset/logos/" + image_a;
} else {
imgPath = "file:///android_asset/logos/" + image_q;
}
Picasso.get().load(imgPath).into(imageView);
linearLayoutNullClick.setVisibility(View.VISIBLE);
recyclerViewKeys.setVisibility(View.GONE);
trueLogo = 2;
} else {
String imgPath = "file:///android_asset/logos/" + image_q;
Picasso.get().load(imgPath).into(imageView);
recyclerViewKeys.setVisibility(View.VISIBLE);
recyclerViewLogoKeys.setVisibility(View.VISIBLE);
}
So is it possible to use the same code and load the imgPath into mediaPlayer = MediaPlayer.create(this, R.raw.music);
I tried loading imgPath directly to mediaplayer like this but didn't work:
mediaPlayer = MediaPlayer.create(this, imgPath);
Then i tried:
private String audioPath;
audioPath = imgPath;
mediaPlayer = MediaPlayer.create(this, audioPath);
but also didn't work.
Tried many more methods i found on the web, but always i am missing something
As i said before i am a newbie in coding and programming so the solution probably will be very easy .
Anyone can help please?
Are you sure you are getting a audio path in your imgPath object?
Then you can try getting actual storage path from device using code mentioned
here
If you change the value in the database of pic_1.png with audio_1.mp3
then path will start like:
"file:///android_asset/logos/" + YOUR_AUDIO;
So are you sure audio exists in this path?

Playing 2 musics through 2 different sound cards at same time

Trying something pretty out of the box... I have a simple app with a button that when pushed, plays music out of the audio jack of my android tablet.
public void btn1 (View view) {
MediaPlayer mp = MediaPlayer.create(this, R.raw.xxx);
mp.start();
}
I've now added a usb audio interface (through a micro usb adapter) and I can hear audio out of it.
I'm able to list the sound cards with this
AudioDeviceInfo[] devices = audioManager.getDevices(AudioManager.GET_DEVICES_OUTPUTS);
for (AudioDeviceInfo device : devices) {
int b = device.getId();
int d = device.getType();
CharSequence productName = device.getProductName();
}
How do I route music so that I can play 2 different music at once, one through usb and the other through the headphone jack?
According to the MediaPlayer documentation, you can set the audio device using setPreferredDevice which receive an AudioDeviceInfo as a parameter, see https://developer.android.com/reference/android/media/MediaPlayer.html#setPreferredDevice(android.media.AudioDeviceInfo).
You will then have to create one MediaPlayer to play on each device.
it works about like this:
protected void playAudio() {
this.playByDeviceIdx(0, R.raw.xxx);
this.playByDeviceIdx(1, R.raw.yyy);
}
protected void playByDeviceIdx(int deviceIndex, #IdRes int resId) {
/* obtain audio-output device-infos */
deviceInfos[] devices = audioManager.getDevices(AudioManager.GET_DEVICES_OUTPUTS);
/* check, if the desired index is even within bounds */
if(deviceInfos.length < deviceIndex) {
/* create an instance of MediaPlayer */
MediaPlayer mp = MediaPlayer.create(this, resId);
/* assign a preferred device to the MediaPlayer instance */
mp.setPreferredDevice(deviceInfos[deviceIndex]);
/* start the playback (only if a device exists at the index) */
mp.start();
}
}
you could also filter for the headset jack plug/unplug event:
IntentFilter intentFilter = new IntentFilter(Intent.ACTION_HEADSET_PLUG);
Intent intent = context.registerReceiver(null, intentFilter);
boolean isConnected = intent.getIntExtra("state", 0) == 1;
sources: me, based upon the SDK documentation for the MediaPlayer.

Android MediaPlayer seekTo() doesn't work

I have an Android app with two media players close to eachother, playing videos. The loop is enabled. When it is running, I notice one of the videos get a bit off from the other for a few hundred ms which is noticeable. The two videos are crops of the same video that's why when the guy moves, it gets clear there is an edge. I was trying to manually add a few milliseconds to the other one using
mp[1].seekTo(mp[0].getCurrentPosition()+700)
but unfortunately it gets off as time passes. And everytime it gets different. I was using Thread and set the mediaPlayer.start() of the two players at the same time (as this post suggested), but that also didn't help. How can I solve the problem? Any thoughts?
mp[0] = mediaPreparation("waldo_short_1.mp4", false);
mp[1] = mediaPreparation("waldo_short_2.mp4", false);
mp[0].start();
mp[1].start();
mp[1].seekTo(mp[0].getCurrentPosition()+705);
MediaPlayer mediaPreparation(String filename, boolean setMute) {
// create mediaplayer instance
MediaPlayer mediaPlayer = new MediaPlayer();
AssetFileDescriptor afd;
try {
afd = getContext().getAssets().openFd(filename);
mediaPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
afd.close();
mediaPlayer.prepare();
} catch (IOException e) {
}
mediaPlayer.setLooping(true);
// mediaPlayer.start();
return mediaPlayer;
}

Creating a music player with javafx and scene builder

I'm trying to create my own version of iTunes. I am trying to create a music player and this is my method:
public void audioPlayerButtons(ActionEvent actionEvent) {
if (actionEvent.getSource() == playbtn) {
String bip = "/Users/april121/Work/MyMusic!/src/sample/Songs/01 Clarity.m4a";
Media hit = new Media(bip);
MediaPlayer mediaPlayer = new MediaPlayer(hit);
MediaPlayer.play();
}
else (actionEvent.getSource()== pausebtn){
MediaPlayer.pause();
}
else (actionEvent.getSource()==forwardbtn){
MediaPlayer.seek(MediaPlayer.getStartTime());
MediaPlayer.stop();
}
else (actionEvent.getSource()==backwardbtn){
//to be finished
}
But I have tried for hours now - be it through importing libraries from Maven or hard coding and it's not working.
I'd like it show what's playing and have basic functions ie. play, pause, rewind and forward and have a progress bar.
this is the error it is showing:
non-static method can't be accessed in static context. And the part that is causing the error is the ".stop()" or ".play()" bits
but I don't understand why - because my method is non-static anyways
Look at these lines:
MediaPlayer mediaPlayer = new MediaPlayer(hit);
MediaPlayer.play();
That second line is calling a static play() function, which doesn't work. The play() function is non-static. That's why you're getting the error you're getting.
You probably mean this instead:
MediaPlayer mediaPlayer = new MediaPlayer(hit);
mediaPlayer.play();
If you have other questions, post them as separate questions and try to be as specific as possible.
Try naming it something else ie.
MediaPlayer mp = new MediaPlayer (hit);
mp.play();
That way you won't have a confusion!

Check and see if a sound is playing, wait for it to finish and then play another

What i am trying to acomplish is for me to click on a button and then play a sound based on a substring.
This is my current code for pressing the button :
display.setText("start");
thefull = thef.getText().toString();
for(int a=0;a<thefull.length();a++)
{
letter=thefull.substring(a,a+1);
if(letter=="m")
{
oursong = MediaPlayer.create(MainActivity.this, R.raw.m);
oursong.start();
while(oursong.isPlaying())
{
display.setText("start");
}
oursong.release();
}
else if(letter=="a")
{
oursong = MediaPlayer.create(MainActivity.this, R.raw.a);
oursong.start();
while(oursong.isPlaying())
{
display.setText("start");
}
oursong.release();
}
display.setText("done");
but for some reason when i click my button no sound is played.
I am also new to android and java programming, so am i going right about doing this?
Because what i really want is for the program to keep checking if a sound is playing(in this case "oursound) when the button is clicked and if the sound is playing i want the program to wait for it to finish to start another sound right after it.
But for now my code doesn´t play any sounds
First of all you need to stop the media player before releasing it(its safer.)
Second, instead of using while(oursong.isPlaying())
{
display.setText("start");
} ; you have to register OnCompletionListener using setOnCompletionListener method. When the song is played endCompletion will be called. Like so;
MediaPlayer mp = new MediaPlayer();
mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener(){
public void onCompletion(MediaPlayer player) {
player.release();
}});
and inside the onComplete should reset the text "done"
