Android VideoView无法播放视频mp4

我使用Android VideoView通过HTTP播放视频文件。我的问题是，从HTTP播放mp4文件时，手机会提示“无法播放视频对不起，无法播放此视频”。但在播放另一个mp4视频文件时也可以

在三星Galaxy S等较新手机上使用时，我的程序可以成功地从HTTP播放mp4视频文件

public class VideoPlayActivity extends Activity {
VideoView vv;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    //requestWindowFeature(Window.FEATURE_NO_TITLE);
    //getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

    vv = new VideoView(this);
    RelativeLayout.LayoutParams param1 = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
    param1.addRule(RelativeLayout.CENTER_IN_PARENT);
    vv.setOnErrorListener(new OnErrorListener() {

        public boolean onError(MediaPlayer mp, int what, int extra) {
            Log.d("Dbg", "OnErrorListener: onError: " + what + ", " + extra);
            return false;
        }

    });

    RelativeLayout layout = new RelativeLayout(this);
    layout.addView(vv, param1);

    setContentView(layout);

    playContent();

 }

 private void playContent() {
    String path = "http://rmcdn.2mdn.net/MotifFiles/html/1248596/android_1330378998288.mp4";

    vv.setVideoPath(path);
    vv.requestFocus();
    vv.start();
    }
}

我的电话：

Samsung GT-S5830  
Android version: 2.3.4  
Display: 320x480.

Video file 1 (OK):  
Video Codec: H.264  
Resolution: 640x360  
Others: 16:9, 340kbps, 29.92fps  
Audio Codec: AAC, 44kHz 96kbps Stereo.


Video file 2 (Fail):  
Video Codec: H.264  
Resolution: 640x360  
Others: 16:9, 993kbps, 25fps  
Audio Codec: AAC 44kHz 125kbps Stereo.

下面是我成功播放视频文件1的硬编码代码

public class VideoPlayActivity extends Activity {
VideoView vv;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    //requestWindowFeature(Window.FEATURE_NO_TITLE);
    //getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

    vv = new VideoView(this);
    RelativeLayout.LayoutParams param1 = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
    param1.addRule(RelativeLayout.CENTER_IN_PARENT);
    vv.setOnErrorListener(new OnErrorListener() {

        public boolean onError(MediaPlayer mp, int what, int extra) {
            Log.d("Dbg", "OnErrorListener: onError: " + what + ", " + extra);
            return false;
        }

    });

    RelativeLayout layout = new RelativeLayout(this);
    layout.addView(vv, param1);

    setContentView(layout);

    playContent();

 }

 private void playContent() {
    String path = "http://rmcdn.2mdn.net/MotifFiles/html/1248596/android_1330378998288.mp4";

    vv.setVideoPath(path);
    vv.requestFocus();
    vv.start();
    }
}

播放视频文件2时的错误日志如下：

11-19 17:49:30.119: I/VideoView(16860): start()  
11-19 17:49:30.139: E/MediaPlayer(16860): error (1, -2147483648)  
11-19 17:49:30.149: E/MediaPlayer(16860): Error (1,-2147483648)  
11-19 17:49:30.149: D/VideoView(16860): Error: 1,-2147483648  
11-19 17:49:30.149: D/Dbg(16860): OnErrorListener: onError: 1, -2147483648  

值得注意的是，我试图安装MX播放器，并将这两个视频文件下载到手机的SD卡中。MX播放器可以成功播放两个视频文件

public class VideoPlayActivity extends Activity {
VideoView vv;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    //requestWindowFeature(Window.FEATURE_NO_TITLE);
    //getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

    vv = new VideoView(this);
    RelativeLayout.LayoutParams param1 = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
    param1.addRule(RelativeLayout.CENTER_IN_PARENT);
    vv.setOnErrorListener(new OnErrorListener() {

        public boolean onError(MediaPlayer mp, int what, int extra) {
            Log.d("Dbg", "OnErrorListener: onError: " + what + ", " + extra);
            return false;
        }

    });

    RelativeLayout layout = new RelativeLayout(this);
    layout.addView(vv, param1);

    setContentView(layout);

    playContent();

 }

 private void playContent() {
    String path = "http://rmcdn.2mdn.net/MotifFiles/html/1248596/android_1330378998288.mp4";

    vv.setVideoPath(path);
    vv.requestFocus();
    vv.start();
    }
}

那么，有人能帮我回答以下问题吗

11-19 17:49:30.119: I/VideoView(16860): start()

为什么我的程序无法在手机上播放视频文件2

如何在手机上播放视频文件2

谢谢你的建议。

谢谢你的回答

我发现视频文件2被编码在H.264主配置文件中，我的手机无法播放。建议在基线配置文件中使用H.264。因此，在将视频转换为基线配置文件后，它可以在我的手机上播放。

感谢您的提问和回答，我正在尝试在videoview上播放视频，但遇到了相同的问题，我不明白主配置文件和基线配置文件是什么意思？我如何以及在哪里可以找到更多关于他们的信息？谢谢你在运行时转换它吗？@tim你能回答rudis的问题吗？
