Try this i used this worked for me:

import com.github.hiteshsondhi88.libffmpeg.ExecuteBinaryResponseHandler;

import com.github.hiteshsondhi88.libffmpeg.FFmpeg; import com.github.hiteshsondhi88.libffmpeg.LoadBinaryResponseHandler; import com.github.hiteshsondhi88.libffmpeg.exceptions.FFmpegCommandAlreadyRunningException; import com.github.hiteshsondhi88.libffmpeg.exceptions.FFmpegNotSupportedException;

public class Home extends Activity {

private static final String TAG = Home.class.getSimpleName();

FFmpeg ffmpeg;
File imageFile;
File f;
File myDirectory = new File(Environment.getExternalStorageDirectory() + "/Your_directory/");
File outputDirectory;
@Bind(R.id.command)
EditText commandEditText;
@Bind(R.id.command_output)
LinearLayout outputLayout;
String paths = "";
String path2 = "";
private ProgressDialog progressDialog;
String fileName;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_home);
    ButterKnife.bind(this);
    isStoragePermissionGranted();
    if (getIntent().getStringExtra("name") != null) {
        fileName = getIntent().getStringExtra("name");
        outputDirectory = new File(Environment.getExternalStorageDirectory() + "/Your_dir/" + fileName + ".mp4");
    } else {
        outputDirectory = new File(Environment.getExternalStorageDirectory() + "/Your_dir/test" + System.currentTimeMillis() + ".mp4");

    }

    commandEditText.setEnabled(false);

    paths = "path of video";


    ffmpeg = FFmpeg.getInstance(this);
    loadFFMpegBinary();
    initUI();


    if (!myDirectory.exists()) {
        myDirectory.mkdirs();
    }

    f = new File(Environment.getExternalStorageDirectory() + "/your_dir/trial.mp3");

        byte[] buffer = new byte[size];
        is.read(buffer);
        is.close();


        FileOutputStream fos = new FileOutputStream(f);
        fos.write(buffer);
        fos.close();
    } catch (Exception e) {

USE THIS IT WORK FOR ME USE FFMPEG LIBRARY ,I HAVE PROVIDED THE IMPORTS AT THE TOP HERE IS THE LIBRARY https://github.com/WritingMinds/ffmpeg-android-java
