FFmpegMediaPlayer Stops When Network is Turned Off and Back On
18 mai 2017, par FallasI am currently working with FFmpegMediaPlayer in order to make a basic music player given a url. I got the basic functionality to work. On error, I show an error message, else I play the songs.
The problem I am facing is, once the player starts, and I turn off my wifi and phone data, it stops the sound. Once I turn my wifi or phone data back one, I would like the player to continue but it simply stops. I have to stop and play again for it to continue.Is there a way to have the FFmpegMediaPlayer continue streaming ?
This is what I have to initialize the player :
mMediaPlayer = new FFmpegMediaPlayer();
mMediaPlayer.setOnErrorListener(this);
mMediaPlayer.setOnPreparedListener(this);
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mMediaPlayer.setOnBufferingUpdateListener(this);
mMediaPlayer.setOnSeekCompleteListener(this);
try {
Uri uri = Uri.parse(radio_url);
mMediaPlayer.setDataSource(mMainActivity, uri);
mMediaPlayer.prepareAsync();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (SecurityException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}Then I have a function to handle when Play/Stop button is clicked :
@Override
public void onPlayButtonClicked(Button button) {
if (radioInitialized) {
mAnalytics.onStopButtonClicked();
mMainLayout.loading(false);
mMediaPlayer.pause();
button.setBackground(mMainActivity.getResources().getDrawable(R.drawable.play_button));
radioInitialized = false;
} else {
mAnalytics.onPlayButtonClicked();
mMainLayout.loading(true);
initRadio();
button.setBackground(mMainActivity.getResources().getDrawable(R.drawable.stop_button));
radioInitialized = true;
}
}Again, the basic functionality works, but I would like for it to continue streaming after wifi is turned back on.
