Soo this project I toyed around with the live video screen and changed a small part of it to gray colour and the rest of it was a normal BGR screen!!
Demo:
Things Required:
- Jetson Nano
- Keyboard
- Mouse
- HDMI Screen
- Raspberry Pi Camera
- External Power Supply
Reference Material:
- You can check out this video for the project: (LINK)
Code:
Note that code below is in python

import cv2
dispW=640
dispH=480
flip=2
camSet='nvarguscamerasrc ! video/x-raw(memory:NVMM), width=3264, height=2464, format=NV12, framerate=21/1 ! nvvidconv flip-method='+str(flip)+' ! video/x-raw, width='+str(dispW)+', height='+str(dispH)+', format=BGRx ! videoconvert ! video/x-raw, format=BGR ! appsink'
cam=cv2.VideoCapture(camSet)
while True:
ret, frame= cam.read()
roi=frame[50:250, 200:400].copy()
roi_gray= cv2.cvtColor(roi, cv2.COLOR_BGR2GRAY)
roi_gray= cv2.cvtColor(roi_gray, cv2.COLOR_GRAY2BGR)
frame[50:250, 200:400]=roi_gray
cv2.imshow('nanoCam', frame)
if cv2.waitKey(1) == ord('q'):
break
cam.release()
cv2.destroyAllWindows()
