String path = Environment.getExternalStorageDirectory()
                + "/gif/wall.jpg";
        String tmp = Environment.getExternalStorageDirectory() + "/gif/tmp";
        System.out.println(path);
        Clip clip = new Clip(path);
        File f = new File(tmp);
        try {
            f.createNewFile();
        } catch (IOException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
        try {
            FfmpegController controller = new FfmpegController(this, f);
            controller.convertImageToMP4(clip, 5,
                    Environment.getExternalStorageDirectory()
                            + "/gif/mynew.mp4", new ShellCallback() {

                        @Override
                        public void shellOut(String shellLine) {
                            // TODO Auto-generated method stub

                        }

                        @Override
                        public void processComplete(int exitValue) {
                            // TODO Auto-generated method stub

                        }
                    });

        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

This is the syntax for ffmpeg to convert a gif to mp4:

ffmpeg -f gif -i infile.gif outfile.mp4

The android command line version of ffmpeg will be very similar.

This javadoc explains how to use the android-ffmpeg library to run commands on ffmpeg.

Hope that helps

thanks jodes for giving your time but where to enter this command line in android app do you have an any example for this...? – Hardik Oct 07 '14 at 10:11
in above library in my question has a method name "public Clip convertImageToMP4 ()" which is doing the same that you wrote in your answer but it is not working – Hardik Oct 07 '14 at 10:19
you can see this class https://github.com/guardianproject/android-ffmpeg-java/blob/master/src/org/ffmpeg/android/FfmpegController.java has a method convertImageToMP4 () – Hardik Oct 07 '14 at 10:20
What have you tried? Have you tried using the method? What happens when you try? Please post code, with the problem you have? – Jodes Oct 08 '14 at 16:42
