从服务器android播放mp4视频

Question

I want to play video of mp4 format and size 4-5Mb from server in streaming mode.I am using sdk version 2.3,on emulator it gives only sound but not any picture.

I also tested it on devices Samsung(android sdk ver 2.1) and LG optimus(android sdk ver 2.2) and only get "cannot play video:sorry this video is not valid for streaming to this device" message. I have searched on this but not getting any solution, if anybody have any solution please help me.Thanks in advance.

Here is my code:

public class ShowVideo extends Activity 
{
   private static ProgressDialog progressDialog;
   public String video_url;
   private  MediaController mediaController;

   @Override
   protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.videoalbum);

    progressDialog = ProgressDialog.show(ShowVideo.this, "", "Buffering video...", true);
    getWindow().setFormat(PixelFormat.TRANSLUCENT); 

    video_url = "http://www.letumobi.com/videouploads/cd0a4170-1fb2-4fba-b17c-b5d70b2cd2e7.mp4";

        try {
                final VideoView videoView =(VideoView)findViewById(R.id.video_viewId);
                mediaController = new MediaController(ShowVideo.this);
                mediaController.setAnchorView(videoView);
                // Set video link (mp4 format )
                Uri video = Uri.parse(video_url);
                videoView.setMediaController(mediaController);
                videoView.setVideoURI(video);

                videoView.setOnPreparedListener(new OnPreparedListener() {

                    public void onPrepared(MediaPlayer mp) {
                        progressDialog.dismiss();
                       videoView.start();
                    }
                });

             }catch(Exception e){
                  progressDialog.dismiss();
                 System.out.println("Video Play Error :"+e.getMessage());
             }

    }

Answer 1

On emulator it is difficult to get video played, because it needs really fast computer. Try this link for emulator. Maybe you can get some discrete video view.

Also in your real devices this link should work if your implementation is proper.

I assume your video using following link " http://www.letumobi.com/videouploads/cd0a4170-1fb2-4fba-b17c-b5d70b2cd2e7.mp4 is not proper for safe streaming.

You should hint that video or play other hinted videos. I couldn't find any other solution for playing unhinted videos yet.

You may try these urls (ends with .3gp) :

http://daily3gp.com/vids/747.3gp 
http://daily3gp/www/vids/juggling_while_on_unicycle.3gp 

instead of .mp4 urls:

video_url = "http://www.letumobi.com/videouploads/cd0a4170-1fb2-4fba-b17c-b5d70b2cd2e7.mp4";
