just a heads up im stuck

Right now, the goal is to have a camera to detect if the orange ball is still on the plane- if yes, timer runs/ if not, timer stops. 

I have tried a few methods to achieve this but every one of it doesn’t work.

• Processing + Macbook Facetime HD Camera
  Used the ‘Video’ library of Processing
  Problem as per screenshot:
  Unfortunately, I am on a macOS Catalina ver 10.15.5https://github.com/processing/processing-video/issues/134
  Tried the solution as suggested by ihaveaccount on this above forum but the string doesn’t return as they said it wouldwithout the video library, this eliminates the use of external webcams also (i tried with my DSLR as a webcam)
  
• Processing + IP Camera
  Since I was hoping for the webcam to be portable anyway, I tried to use an IP Camera. 
  Problem: On my processing sketch, nothing shows up, no error, no video feed show- nothing. IP camera doesn’t show it is being connected to anything either.
  
  Not sure if its because im accessing processing via a Macbook and im using an android IP Camera app?
• TouchDesigner + IP Camera
  Used the Video Stream in, and with RSTP network protocol, while yes there is a video feed, it is SOOO choppy and pretty much only refreshes when I “pulse” the node
• TouchDesigner + Web Camera

  Once again seems like everyone else with Mac ver after 10.14, webcam doesnt seem to work
  I did try with the latest beta ver of Touchdesigner however, it only works when I first start a timeline, once I save the file and close it and then reopen, its just a black screen again.

So now Im stuck. Im thinking maybe a Raspberry PI(since it runs Windows) with a webcam, or a camera module and maybe something along the line of python w OpenCV library, or it will be great if i could have processing on Raspberry PI. But this is a whole new set of problems because first I don’t have a Raspberry PI and just learning to work it is like 😵🤯😩.
