• How to convert a first 5 sec of a video to gif using ffmpeg

  2 octobre 2019, par chithra

    String livestream = "/home/Downloads/123.MP4";
  
  
  
      String folderpth = "/home/chithra/Downloads/aagiten.gif";
  
  
  
      Runtime.getRuntime().exec(
  
              new String[] {
  
                      "ffmpeg",
  
                      "-i",
  
                      "-t 5",
  
                       livestream,
  
                      folderpth
  
  
  
              }
  
      );

  I tried to add the parameter -t in this code but it is not converting the first 5 seconds of a video.

• Crontab starts again befor the process of conversion in ffmpeg ends(depending on time supose /2 minutes) How to Control that ?

  18 décembre 2016, par A Sahra

  I am running a bash .sh file every two minutes with crontab. the problem is that when crontab runs bash file the process of ffmpeg video conversion starts,the conversion time varies depending on length of videos, i have set the crontab to run every two minutes. crontab runs again after two minutes before end of ffmpeg conversion.

  How to Figure out :

  control of crontab and conversion process so the crontab doesn’t starts again until process of conversion is not completed.
