title: Video capture/record library of desktop/screen " pc not mobile " [c++/Qt]
body: <p>so I've been searching for something like this , either library or a way to do this but either it's for mobiles or it's not for noobs :D</p>
  
  <p>Basically I want to capture a full screen video where the user can stop/start/ save the video in many formats.</p>
  
  <p>I've thought of capturing the screen " images " and combine them but it's going to take a lot of cpu power I think and I think there's a better way.</p>
