Android : Vitamio library: video and audio out of sync

I have included the VitamioBundle library into my project. It plays videos, but the problem is that the video and the audio are out of sync. How can i solve this issue?

Here is my code.

Vitamio.initialize(VideoPlayer.this);
        if (!io.vov.vitamio.LibsChecker.checkVitamioLibs(this))
            return;
        videoView = (VideoView) findViewById(R.id.VideoView);
        videoView.setOnErrorListener(new OnErrorListener() {
            public boolean onError(MediaPlayer mp, int what, int extra) {
                return true;
            }
        });
        videoView.setVideoChroma(MediaPlayer.VIDEOCHROMA_RGB565);
        videoView.setHardwareDecoder(true);
        videoView.setVideoQuality(VIDEOQUALITY_HIGH);
 videoView.setOnPreparedListener(new OnPreparedListener() {
            @Override
            public void onPrepared(MediaPlayer mediaPlayer) {
                mediaPlayer.setPlaybackSpeed(1.0f);
                mediaPlayer.setAdaptiveStream(true);

        }
        });
  videoView.setVideoPath(vlink);
        videoView.requestFocus();

        videoView.setVideoLayout(VideoView.VIDEO_LAYOUT_SCALE, 0);
        videoView.setOnPreparedListener(new OnPreparedListener() {

            public void onPrepared(MediaPlayer mp) {
                videoView.start();

            }
        });
