  public class ScreenCaptureFFMPEG {
  
  
  
      public static void record(String outputVideo, String time) throws Exception
  
      {
  
          RunProcessFunction func = new RunProcessFunction();
  
  
  
          FFmpeg ffmpeg = new FFmpeg("C:\\FFMPEG\\ffmpeg.exe");
  
          FFmpegBuilder builder = new FFmpegBuilder()
  
                  .addExtraArgs("-rtbufsize", "1500M")
  
                  .addExtraArgs("-r", "30")
  
                  .setFormat("dshow")
  
                  .setInput("video=\"screen-capture-recorder\"")
  
                  .addOutput(outputVideo)
  
                  .setFormat("mp4")
  
                  .addExtraArgs("-crf", "0")
  
                  .setVideoCodec("libx264")
  
                  //.addExtraArgs("-ac", "1")
  
                  .addExtraArgs("-y")
  
          //overwrite file name
  
  
  
                  // .setAudioCodec("libmp3lame")
  
                  // .setAudioSampleRate(FFmpeg.AUDIO_SAMPLE_44100)
  
                  //  .setAudioBitRate(1_000_000)
  
  
  
                  //.addExtraArgs("-ar", "44100")

                  .done();
  
          FFmpegExecutor executor = new FFmpegExecutor(ffmpeg);
  
  
  
          executor.createJob(builder).run();
  
  
  
  
  
      }
  
  
  
      public static void capture(String name) throws Exception
  
      {
  
          BufferedImage image = new Robot().createScreenCapture(new Rectangle(Toolkit.getDefaultToolkit().getScreenSize()));
  
          ImageIO.write(image, "png", new File(name));
  
  
  
      }
  
  
  
      public static void main(String[]args) throws Exception {
  
  
  
          capture("start.png");
  
          //record("TC_test.mp4", "00:00:10");
  
          capture("end.png");
  
          Thread t = new Thread(new Runnable() {
  
              @Override
  
              public void run() {
  
                  // Insert some method call here.
  
                  try {
  
                      record("TC_test.mp4", "00:00:10");
  
                  }
  
                  catch(Exception e)
  
                  {
  
                      System.out.println("hello");
  
                  }
  
              }
  
          });
  
          Thread.sleep(5000);
  
  
  
          t.interrupt();
  
  
  
      }
  
  }

  I am trying to stop the recording by killing the subprocess or if there is any other method its fine too. But I am unable to do that. I know its supported according to the github link. How do I kill a subprocess please ?

  PS : THis is the first time i post a question on stackoverflow so If I made any mistakes please excuse me and provide details on how i can improve

  fate/vcodec : stop using the deprecated v308 codec
  stddev and PSNR values change by the removal of format conversion and because
  
  of the added sws_flags. Either or will have the same effect even on their own.
