推荐答案

终于让我找到了答案:)
    我考证一下FFmpeg的似乎更深入，一些多天周围挖，但却无法获得ffmepg
适当的资源，我尝试使用mp4parser的 LIB ，并成功地完成了我的要求。

code对于合并多个视频

Finally i find the answer :)
i research about ffmpeg it seems more deeply and some more days digging around it but can't get
proper resource for ffmepg and i try to use mp4parser lib and successfully completed my requirement.

Code For Merging Multiple Video

public class MergeVide extends AsyncTask<String, Integer, String> {

    @Override
    protected void onPreExecute() {
        progressDialog = ProgressDialog.show(Video.this,
                "Preparing for upload", "Please wait...", true);
        // do initialization of required objects objects here
    };

    @Override
    protected String doInBackground(String... params) {
        try {
            String paths[] = new String[count];
            Movie[] inMovies = new Movie[count];
            for (int i = 0; i < count; i++) {
                paths[i] = path + filename + String.valueOf(i + 1) + ".mp4";
                inMovies[i] = MovieCreator.build(new FileInputStream(
                        paths[i]).getChannel());
            }
            List<Track> videoTracks = new LinkedList<Track>();
            List<Track> audioTracks = new LinkedList<Track>();
            for (Movie m : inMovies) {
                for (Track t : m.getTracks()) {
                    if (t.getHandler().equals("soun")) {
                        audioTracks.add(t);
                    }
                    if (t.getHandler().equals("vide")) {
                        videoTracks.add(t);
                    }
                }
            }

            Movie result = new Movie();

            if (audioTracks.size() > 0) {
                result.addTrack(new AppendTrack(audioTracks
                        .toArray(new Track[audioTracks.size()])));
            }
            if (videoTracks.size() > 0) {
                result.addTrack(new AppendTrack(videoTracks
                        .toArray(new Track[videoTracks.size()])));
            }

            BasicContainer out = (BasicContainer) new DefaultMp4Builder()
                    .build(result);

            @SuppressWarnings("resource")
            FileChannel fc = new RandomAccessFile(String.format(Environment
                    .getExternalStorageDirectory() + "/wishbyvideo.mp4"),
                    "rw").getChannel();
            out.writeContainer(fc);
            fc.close();
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        String mFileName = Environment.getExternalStorageDirectory()
                .getAbsolutePath();
        mFileName += "/wishbyvideo.mp4";
        filename = mFileName;
        return mFileName;
    }

    @Override
    protected void onPostExecute(String value) {
        super.onPostExecute(value);
        progressDialog.dismiss();
        Intent i = new Intent(Video.this, VideoUpload.class);
        i.putExtra("videopath", value);
        i.putExtra("id", id);
        i.putExtra("name", name);
        i.putExtra("photo", photo);
        startActivity(i);
        finish();
        }
}

在计数无非是视频文件的数量

the count is nothing but video file count.

以上$ C $下合并更多的视频和发送的最后code到另一个活动中，我已决定，以preVIEW视频。
使用上述code确保使用mp4parser LIB前。

the above code for merge more video and send the final code to another activity in that i have decided to preview the video.
before using above code make sure use mp4parser lib.
