You can use jcodec `SequenceEncoder` http://stackoverflow.com/questions/20520705/using-jcodec-sequenceencoder/20630238#20630238 — Abhishek V, Jul 03 '15 at 13:13

Please check the below code

Make one file FfmpegController.java

public class FfmpegController {

    private static Context mContext;
    private static Utility mUtility;
    private static String mFfmpegBinaryPath;

    public FfmpegController(Context context) {

        mContext = context;

        mUtility = new Utility(context);

        initFfmpeg();
    }

    private void initFfmpeg()
    {
        /*
        Save the ffmpeg binary to app internal storage, so we can use it by executing java runtime command.
         */

        mFfmpegBinaryPath = mContext.getApplicationContext().getFilesDir().getAbsolutePath() + "/ffmpeg";

        if (Utility.isFileExsisted(mFfmpegBinaryPath))
            return;

        InputStream inputStream = mContext.getResources().openRawResource(R.raw.ffmpeg);

        mUtility.saveFileToAppInternalStorage(inputStream, "ffmpeg");

        Utility.excuteCommand(CommandHelper.commandChangeFilePermissionForExecuting(mFfmpegBinaryPath));
    }

    public void convertImageToVideo(String inputImgPath)
    {
        /*
        Delete previous video.
         */

        Log.e("Image Parth", "inputImgPath - "+inputImgPath);

        if (Utility.isFileExsisted(pathOuputVideo()))
            Utility.deleteFileAtPath(pathOuputVideo());

        /*
        Save the command into a shell script.
         */

        saveShellCommandImg2VideoToAppDir(inputImgPath);

        Utility.excuteCommand("sh" + " " + pathShellScriptImg2Video());
    }

    public String pathOuputVideo()
    {
        return mUtility.getPathOfAppInternalStorage() + "/out.mp4";
    }

    private String pathShellScriptImg2Video()
    {
        return mUtility.getPathOfAppInternalStorage() + "/img2video.sh";
    }

    private void saveShellCommandImg2VideoToAppDir(String inputImgPath)
    {
        String command = CommandHelper.commandConvertImgToVideo(mFfmpegBinaryPath, inputImgPath, pathOuputVideo());

        InputStream is = new ByteArrayInputStream(command.getBytes());

        mUtility.saveFileToAppInternalStorage(is, "img2video.sh");
    }
}

Make another Java file Utility.java

public class Utility {

    private final static String TAG = Utility.class.getName();
    private static Context mContext;

    public Utility(Context context) {
        mContext = context;
    }

    public static String excuteCommand(String command)
    {
        try {
            Log.d(TAG, "execute command : " + command);

            Process process = Runtime.getRuntime().exec(command);

            BufferedReader reader = new BufferedReader(
                    new InputStreamReader(process.getInputStream()));
            int read;
            char[] buffer = new char[4096];
            StringBuffer output = new StringBuffer();
            while ((read = reader.read(buffer)) > 0) {
                output.append(buffer, 0, read);
            }
            reader.close();

            process.waitFor();

            Log.d(TAG, "command result: " + output.toString());

            return output.toString();

        } catch (IOException e) {

            Log.e(TAG, e.getMessage(), e);

        } catch (InterruptedException e) {

            Log.e(TAG, e.getMessage(), e);
        }

        return "";
    }

    public String getPathOfAppInternalStorage()
    {
        return mContext.getApplicationContext().getFilesDir().getAbsolutePath();
    }

    public void saveFileToAppInternalStorage(InputStream inputStream, String fileName)
    {
        File file = new File(getPathOfAppInternalStorage() + "/" + fileName);
        if (file.exists())
        {
            Log.d(TAG, "SaveRawToAppDir Delete Exsisted File");
            file.delete();
        }

        FileOutputStream outputStream;
        try {
            outputStream = mContext.openFileOutput(fileName, Context.MODE_PRIVATE);
            byte[] buffer = new byte[1024];
            int length;
            while ((length = inputStream.read(buffer)) > 0)
            {
                outputStream.write(buffer, 0, length);
            }
            outputStream.close();
            inputStream.close();
        } catch (Exception e) {
            Log.e(TAG, e.getMessage(), e);
        }
    }

    public static boolean isFileExsisted(String filePath)
    {
        File file = new File(filePath);
        return file.exists();
    }

    public static void deleteFileAtPath(String filePath)
    {
        File file = new File(filePath);
        file.delete();
    }
}

Make another file CommandHelper.java

public class CommandHelper {
    public static String commandConvertImgToVideo(String ffmpegBinaryPath, String inputImgPath, String outputVideoPath) {
        Log.e("ffmpegBinaryPath", "ffmpegBinaryPath - "+ffmpegBinaryPath);
        Log.e("inputImgPath", "inputImgPath - "+inputImgPath);
        Log.e("outputVideoPath", "outputVideoPath - "+outputVideoPath);

        return ffmpegBinaryPath + " -r 1/1 -i " + inputImgPath + " -c:v libx264 -crf 23 -pix_fmt yuv420p -s 640x480 " + outputVideoPath;
    }

    public static String commandChangeFilePermissionForExecuting(String filePath) {
        return "chmod 777 " + filePath;
    }
}

When you want to execute code and make images to video please use below code.

AsyncTask asyncTask = new AsyncTask() {

         ProgressDialog mProgressDialog;

         @Override
         protected void onPreExecute() {
            /* mProgressDialog = new ProgressDialog(activity.this);

             mProgressDialog.setMessage("Converting...");

             mProgressDialog.setCancelable(false);

             mProgressDialog.show();*/

             Log.e("Video Process Start", "======================== Video Process Start ======================================");
         }

         @Override
         protected Object doInBackground(Object... params) {

            saveInputImgToAppInternalStorage();
/*           for(int i = 1; i<11 ; i++){
             mFfmpegController.convertImageToVideo(mUtility.getPathOfAppInternalStorage() + "/" + "Img"+i+".jpg");
             }
*/

            mFfmpegController.convertImageToVideo(mUtility.getPathOfAppInternalStorage() + "/" + "img%05d.jpg");
             return null;
         }

         @Override
         protected void onPostExecute(Object o) {
            // mProgressDialog.dismiss();
             Log.e("Video Process Complete", "======================== Video Process Complete ======================================");

             Log.e("Video Path", "Path - "+mFfmpegController.pathOuputVideo());

             Toast.makeText(activity.this, "Video Process Complete", Toast.LENGTH_LONG).show();
             stopSelfResult(lateststartid);
             Common.ScreenshotCounter = 0;
             Common.ScreenshotTimerCounter = 0;
             /*try {
                copyFile(new FileInputStream(mFfmpegController.pathOuputVideo()), new FileOutputStream(Common.strPathForVideos));
            } catch (FileNotFoundException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }*/

         }
     };

Please note:

Captured images must be in format like:

Img00001, Img00002 .......

Because FFMPEG code expects it this way.

is it necessary to have FFmpeg binaries for different platform architecture in order to run this controller? — Shubham AgaRwal, Jun 28 '18 at 12:53

There's plenty of tools for editing videos like INDE, FFMPEG and etc.

INDE has so many functionality to join videos and images.

If you decide to use FFMPEG then this link provides steps for integration of this tool
