title: Stream video from Raspberry Pi 4 while another program uses the pi camera as well
body: <p>I have a raspberry pi 4 with a camera module on it and a pan-tilt hat.
  I've made a project which when started, it uses the feed from the RPI camera, detects a face and center around it. If the person moves, the camera tracks him.</p>
  <p>When I run the .py file through the terminal, it works.
  Now I want to use it with my PC. Therefore, I need to simultaneously run my project in the background AND to steam the feed to my PC somehow.</p>
  <p>From the methods I searched online, I saw that it's possible to use flask and get a URL to use as an IP camera.</p>
  <p>My question is, is it possible to stream the camera feed while my projects runs and tracks the face?</p>
  <p>Thank you.</p>
