The audio stream plays after a few seconds, why?

Question

Android

Good evening.
I threw in the code for playing the audio stream (namely, the radio), I run it on the emulator, I press the start button and the playback starts immediately. On the physical device, after about 30 seconds, what was most interesting in the logs was just the lineb
03-17 23:24:03.809 18672-18684/com.example.radioplayer V/MediaHTTPConnection: mTotalSize is -1
03-17 23:24 :03.819 18672-18682/com.example.radioplayer D/MediaHTTPConnection: setReadTimeOut = 30000ms
Here is the code:

package com.example.radioplayer;

import android.media.AudioManager;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import java.io.IOException;

public class MainActivity extends AppCompatActivity {

    Button button_stop;
    Button button_play;
    public String STREAM_URL = "http://icecast.piktv.cdnvideo.ru/vanya?47";
    private MediaPlayer mPlayer;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        button_stop=(Button) findViewById(R.id.stop);
        button_play=(Button) findViewById(R.id.start);

        button_stop.setEnabled(false);

        mPlayer=new MediaPlayer();
        mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);

        button_play.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View v){
                mPlayer.reset();
                try {
                    mPlayer.setDataSource(STREAM_URL);
                } catch (IOException e) {
                    e.printStackTrace();
                }
                mPlayer.prepareAsync();
                mPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                    @Override
                    public void onPrepared(MediaPlayer mp) {
                        mp.start();
                    }
                });
                button_play.setEnabled(false);
                button_stop.setEnabled(true);
            }

        });

        button_stop.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mPlayer.stop();
                button_stop.setEnabled(false);
                button_play.setEnabled(true);
            }

        });
    }
}

Googled about the lines in the logs - I didn’t find anything sensible, there is no such class

Physical device Samsung Galaxys* ? Android 4.4 or more?
This is a device problem, I solved this problem by connecting another library - Vitamio (connect only the 5th version, but not lower, otherwise a warning will appear in the console that you need to switch to the 5th version, otherwise the application will be blocked, because in the version below there is a vulnerability).
You can see how to connect the library and how to work with it on the site, on github and on stackoverflow .... in general, there is a lot of information
