  I am using ffmpeg tool to work on a screen recording project. When clicked on Start-Recording button, it should continue to record the screen and should produce 10 seconds video clips till the Stop-Button is clicked. For the above code, the process of generating video clips happening but during the process the GUI is being unresponsive to stop the whole process from the GUI.The while loop is going infinite but I am unable to figure out how to stop it by clicking the Stop-Button.

  


  Any other ways or tools suggestion to work on also welcome...
