add additonal check for external camera if builtin one is not working.

[Gagandeep-2003]

Thanks for the PR! I noticed a couple of issues that should be fixed before merging:

Bug in camera fallback

cap.cv2.VideoCapture(1) # ❌ incorrect

This should be reassigned properly:

cap = cv2.VideoCapture(1) # ✅

Resource handling
It’s good practice to cap.release() before re-opening with a new index.

Verification
Sometimes cap.isOpened() is True but frames still can’t be read. You can make it more robust by checking a test frame:

ok, _ = cap.read()
if not ok:
print("[ERROR] No frames captured from webcam.")
cap.release()
sys.exit(1)
