  java.io.IOException : Error running exec() Working Directory : null Environment : null FFmpeg Android merging mp3 and mp4

  



  I am trying following code

  



  public class Minact1 extends Activity{
    String  videoFilePath,audioFilePath,outputFilePath;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.mainact);
        videoFilePath = Environment.getExternalStorageDirectory()
                .getAbsolutePath() + "/sample2.mp4";
        audioFilePath = Environment.getExternalStorageDirectory()
                .getAbsolutePath() + "/abc.mp3";
        outputFilePath = Environment.getExternalStorageDirectory()
                .getAbsolutePath() + "/output.mp4";

        try {


            FFmpeg ffmpeg = FFmpeg.getInstance(this);
            String[] cmd =
                    {"-i " + videoFilePath + " -i " + audioFilePath +
                            " -shortest -threads 0 -preset ultrafast -strict -2 " + outputFilePath};

            ffmpeg.execute(cmd, mergeListener);
        } catch (FFmpegCommandAlreadyRunningException e) {
            e.printStackTrace();

            Toast.makeText(Minact1.this, "" +  e, Toast.LENGTH_SHORT).show();
        }
    }

    ExecuteBinaryResponseHandler mergeListener = new ExecuteBinaryResponseHandler() {
        @Override
        public void onStart() {
            //started
            Toast.makeText(Minact1.this, "started", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onFailure(String message) {
            //failed
            Toast.makeText(Minact1.this, "failed", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onFinish() {
            File output = new File(outputFilePath);
            //Do whatever with your muxed file

            Toast.makeText(Minact1.this, "onFinish", Toast.LENGTH_SHORT).show();
        }
    };
}


  



  I have used following library for FFmpeg

  



  dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'

    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })

    compile 'com.android.support:design:23.1.1'
    compile 'com.writingminds:FFmpegAndroid:0.3.2'

    compile 'com.android.support:cardview-v7:23.1.1'
    compile 'commons-io:commons-io:2.5'
}


  



  and added following permission in manifest

  



  
    


  



  the files are present at the path used , but output.mp4 is not created

  



  the log says
