Sorry, this video is not valid for streaming to th

I can stream some videos from URL (server) successfully,

But the others (my video up to my server) is not.

You can see both in my code (Working/Not working) I'm on stuck with this problem. "Sorry, this video is not valid for streaming to this device"

The following code :

String url = null;
    //      url = "rtsp://v5.cache5.c.youtube.com/CiILENy73wIaGQmC00ZlwwIDOxMYDSANFEgGUgZ2aWRlb3MM/0/0/0/video.3gp"; // Working
    //      url = "http://daily3gp.com/vids/747.3gp"; // Working
    url = "http://www.ooklnet.com/files/381/381489/video.mp4"; // Working
    //      url = "rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115k.mov"; // Working
    //      url = "http://dl.dropbox.com/u/80419/santa.mp4"; // Working

    //      url = "http://trekvn.hostoi.com/encode_normal.mp4"; // Not Working
    //      url = "http://trekvn.hostoi.com/output_encode_mp4_box.mp4"; // Not Working
    //      url = "http://www.ourserversite.com:14556/ingCloud/users/400010001/mp4_320p/e8d8535852a98c949640c5d618ac23d320131022174507.mp4"; // Not Working
    //      url = "http://trekvn.hostoi.com/mpeg_2_ts.ts"; // Not Working

    videoviewer.setVideoURI(Uri.parse(url));

    videoviewer.requestFocus();
    videoviewer.setKeepScreenOn(true);
    videoviewer.setOnErrorListener(this);
    videoviewer.setOnPreparedListener(this);

@Override
    public void onPrepared(MediaPlayer mp) {
           videoviewer.start()'
}

All of these video can play good on the site, have format *.mp4 (mpeg-4 part 10), Video : .H264, Audio : aac.

Please tell me why, and how to fix it.

p/s : Samsung Galaxy Tab 7" - 2.2.1

Thanks,

This is the issue that many people met, ensure you understand following content to fix the issue.

Through my experience and the answer in this Sorry, this video cannot be played - streaming mp4 to android

Finally, I found the reason and the solution:

- Reason : Almost the *.mp4 file was produced for developing focus on iOS, and have the encoding : H264 Main. While Android side can only stream & play the files have the encoding : H264 Baseline.

- Solution : We need convert from the encoding H264 Main to H264 Baseline (guaranteed enabled Web Optimized (move -moov atom before -mdat) feature)

- Bugs :
