The camera permission authorization window cannot pop up on macOS

[cavivie]

I'm trying a simple opencv demo of reading the camera on macOS Sequoia 15.1. Strangely, it doesn't pop up any authorization windows. I confirmed that I can pop up the authorization window in other terminals (built-in terminal/warp/iterm2). Even though I reset the camera service with tccutil it didn't help (tccutil reset Camera).

I'm using rioterm 0.2.1 (also 0.2.2) from homebrew, macOS version is Sequoia 15.1, .

import numpy as np
import cv2 as cv

cap = cv.VideoCapture(0)
if not cap.isOpened():
    print("Cannot open camera")
    exit()
while True:
    # Capture frame-by-frame
    ret, frame = cap.read()

    # if frame is read correctly ret is True
    if not ret:
        print("Can't receive frame (stream end?). Exiting ...")
        break
    # Our operations on the frame come here
    gray = cv.cvtColor(frame, cv.COLOR_BGR2GRAY)
    # Display the resulting frame
    cv.imshow('frame', gray)
    if cv.waitKey(1) == ord('q'):
        break

# When everything done, release the capture
cap.release()
cv.destroyAllWindows()

To run this example you need to pip install opencv-python and numpy libraries.

As a supplement, I tested accessing special folders such as Desktop/Documents/Downloads on macOS (these folders require authorization), and rio was able to issue authorization normally.

Hey @cavivie thanks for the issue!

Hmmm, very interesting. It's a bit weird because Rio does request camera access

rio/misc/osx/Rio.app/Contents/Info.plist

Lines 126 to 127 in 67e64ae

	<key>NSCameraUsageDescription</key>
	<string>An application in Rio would like to access the camera.</string>

i wonder if there's anything missing

Ah, yes, at first I thought Rio won't request the camera permission, but now it seems that this may require further debugging. I want to know if you can reproduce it?
