How Can I Simulate The Simulate The Space Bar Using Face Detection?

I have written a program that detects my face and tracks my face in the webcam frame. Now, say i am watching a video and my face detection program is running in the background, so when no face is detected the program should pause the VLC media player and play it only when it detects my face. Since, the faces that is detected is stored in a vector, i have tried to write an if statement like
if(faces.size()==0) {keybd_event(VK_SPACE,0,0,0); but the problem is it keeps pressing the space bar continously and i want it to press it just once and then exit the loop. Also, it should automatically press the space bar when it detects my face by pressing the space bar once. How can i do this? I am really confused.

Just set a flag telling you that the video is paused (or not)

So use something like

C#

if (!videoIsPaused && !faceRecognised)
{
  PauseVideo();
  videoIsPaused = true;
}
if (videoIsPaused && faceRecognised)
{
  UnPauseVideo();
  videoIsPaused = false;
}
