mediaPlayer.seekTo(); 每次都到同一位置

seekbar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
@Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {

        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {

        }

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {
            currentProgress = seekBar.getProgress();
            Log.e("currentProgress", String.valueOf(currentProgress));
            if (mediaPlayer != null) {
                mediaPlayer.seekTo(currentProgress);
            }
        }
    });
            currentProgress的值是正确的但是mediaPlayer.seekTo(currentProgress);每次都到同一个位置 求指点啊着啊，，

可能是你的视频格式问题，是mp4吗
