Проблема с воспроизведением Android MediaPlayer

У меня возникают проблемы, когда я использую Android MediaPlayer Class для воспроизведения готового видео.

1. Я просмотрел MediaClass Android SDK и диаграмму состояний. Насколько я могу судить, после завершения воспроизведения видео вы сможете вызвать start () и запустить его с самого начала.
2. Однако, когда я воспроизводю файл RSTP, я получаю следующие ошибки:

01-10 11: 36: 49.138: E / MediaPlayer (4821): error (-2147483648, 0)
01-10 11:36: 49.146: E / MediaPlayer (4821): error (1, -1) < br> 01-10 11: 36: 49.154: E / MediaPlayer (4821): Ошибка (-2147483648,0)
01-10 11:36: 49.162: E / MediaPlayer (4821): Попытка вызвать getDuration без действительный медиаплеер
01-10 11: 36: 49.162: E / MediaPlayer (4821): error (-38, 0)
01-10 11: 36: 49.169: E / MediaPlayer (4821): Error (1 , -1)
01-10 11: 36: 49.185: E / MediaPlayer (4821): Ошибка (-38,0)

3. Последняя проблема возникает, когда я воспроизводю MPG4 на веб-сайте. После повторного нажатия кнопки воспроизведения видео не отображается, а полоса поиска выходит из синхронизации.

Ниже мой код для Activity.

public class CustomMediaPlayer extends Activity implements MediaPlayerControl,
        OnCompletionListener, OnErrorListener, OnInfoListener,
        OnPreparedListener, OnSeekCompleteListener, OnVideoSizeChangedListener,
        SurfaceHolder.Callback, OnBufferingUpdateListener {
