  The current study tries to insert a logo to your project but I like and fix error-start button pressed and the Bobcats have a reaction whenNot sure I understand this : this movie = watermarklogo.png. Do not write down the path to the logo file directly simply put this path in c :\graphics\watermarklogo.png ?

• ffmpeg. I correct that to insert the logo

  There is no response that I push the start button.
  There is no response that I push the start button that I tried to fix the code that I
  inserted the logo in the movie with Ffmpeg.
  Is that be okay if I don't choose the path of logo File. and Is there any something wrong that I did.

      Process jalan = Runtime.getRuntime().exec(cmd);
  
      // Get output stream to write from it
  
      OutputStream keluaran = jalan.getOutputStream();
  
      System.out.println(keluaran);
  
  } catch (IOException e) {
