安卓 2.2 视频视图 "Sorry, Video cannot be played" 与 H264 .MP4

Question

我有一个活动，播放渐进式流媒体视频，编码如下:

布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <VideoView android:id="@+id/myVideo"
         android:layout_width="fill_parent"
         android:layout_height="fill_parent"
         android:layout_gravity="center"/>
</LinearLayout>

活动

public class PlayVideo extends Activity {
    public ProgressDialog progressDialog;
    /** Called when the activity is first created. */
    @Override
    public void onCreate( Bundle savedInstanceState ) {
        super.onCreate( savedInstanceState );
        setContentView( R.layout.video );
        progressDialog = ProgressDialog.show( this, "", "Loading...", true );
        Intent i = getIntent();
        startVideo( i.getStringExtra( "videoUrl" ) );
    }
    public void startVideo( String videoUrl ) {
        final VideoView videoView = ( VideoView ) findViewById( R.id.myVideo );
        videoView.setMediaController( new MediaController( this ) );
        videoView.setVideoURI( Uri.parse( videoUrl ) );
        videoView.setOnPreparedListener( new OnPreparedListener() {
            public void onPrepared( MediaPlayer arg0 ) {
                progressDialog.dismiss();
                videoView.requestFocus();
                videoView.start();
            }
        } );
    }    
}

这在大多数设备上都很好，但是我的客户有两个设备，一个是运行2.2的三星galaxy ace。另一个是video U8150(运行2.2)，视频在这两个设备上都无法播放。视频有一个错误，弹出并说"对不起，这个视频不能播放"，而音频在后台播放，三星只是有同样的错误，然而，当插入ddms的唯一输出可能表明一个错误是:

09-05 15:11:03.461: ERROR/QCvdec(95): Omx Flush issued when vdec is not initialized yet.

09-05 15:11:03.461: ERROR/QCvdec(95): Omx Flush issued when vdec is not initialized yet.

我已经编码了视频在H264+AAC使用这里描述的设置:http://developer.android.com/guide/appendix/media-formats.html并确保moov原子在正确的地方与qt-fastart等。参见:http://www.sciencelearn.org.nz/content/download/7366/430467/version/14/file/08-future-of-radio-telescopes-sllg-ws.mp4

视频在2.3.3、摩托罗拉Xoom、Galaxy S、Galaxy Tab上播放良好;HTC欲望。什么好主意吗?

参考android的默认视频编解码器，http://developer.android.com/guide/appendix/media-formats.html，H.263 MPEG-4 (.mp4)，是2.2设备的好选择…

或替代选项请参考问题:Android上的FFmpeg
