FFMPEGCommand:

    String[] ffmpegCommand = {"/data/data/com.example.app/ffmpeg", "-r", ""+VIDEO_FRAME_RATE, "-b", "1000", "-vcodec", "mjpeg", "-i", Environment.getExternalStorageDirectory().getPath() + "/com.example.app/frame_%05d.jpg", Environment.getExternalStorageDirectory().getPath() + "/video.mov"};

    ffmpegProcess = new ProcessBuilder(ffmpegCommand).redirectErrorStream(true).start();

Its been fixed while I have re-execute the .so files and makes path like this:

String[] ffmpegCommand = {"/data/data/com.example.app/ffmpeg", "-r", ""+VIDEO_FRAME_RATE, "-vcodec", "mjpeg", "-i", Environment.getExternalStorageDirectory().getPath() + "/com.example.app/frame_%105d.jpg",  Environment.getExternalStorageDirectory().getPath() + "/com.example.app/video.mov"};

ProcessBuilder builder = new ProcessBuilder(ffmpegCommand);  
        Map<String, String> env = builder.environment();
        env.put("LD_LIBRARY_PATH", "/data/data/com.example.app:$LD_LIBRARY_PATH");

        ffmpegProcess = builder.redirectErrorStream(true).start();  

            OutputStream ffmpegOutStream = ffmpegProcess.getOutputStream();
            BufferedReader reader = new BufferedReader(new InputStreamReader(ffmpegProcess.getInputStream()));

            String line;

            Log.v("ss","***Starting FFMPEG***");
            while ((line = reader.readLine()) != null)
            {
                Log.v("asd","***"+line+"***");
            }
            Log.v("asdas","***Ending FFMPEG***");

From quick look at your error, there is null instead of full path to the input file for ffmpeg.

So, replace 

 Environment.getExternalStorageDirectory().getPath() + "/com.example.app/frame_%05d.jpg"

with follow pseudo code.

get a File instance on the input jpg.

  myInputJpg.getAbsolutePath()

may provide a non-null ffmpeg file handle for the input...
