android 媒体播放器播放预告片

Question

我想使用以下代码播放上面的预告片，但它不起作用，抛出以下错误

Command PLAYER_INIT Completed with an error or info PVMFFailure 02-02 13:40:33.696: 错误/MediaPlayer(805): 错误 (1, -1) 02-02 13:40:33.706: 错误/MediaPlayer(805): 错误 (1,-1)

private final void playTrailler(String url)throws IOException, IllegalArgumentException {
        MediaPlayer mp = new MediaPlayer();
        Log.v(TAG, "Trailler: " + url);
        mp.setDataSource(url);
        mp.setOnPreparedListener(this);
        mp.prepareAsync();
    }


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

    }
