Change resolution and FPS using OpenCV

[arthurkehrwald]

First of all thanks a lot for making this!

I am trying to use the PS3 Eye in OpenCV with Python. It works, but I cannot change the resolution and fps. It always runs at 640x480, 30fps. Using the same camera and the same computer on Ubuntu (dual boot), I can change the parameters just fine, so it must be a software issue.

When I use VideoCapture.set(), I get the following error:
libusb: warning [init_root_hub] could not get node connection information (V2) for root hub 'USB\ROOT_HUB30\4&547E2CA&0&0' port 15: [87] The parameter is incorrect.

I followed the instructions you have linked in the Readme and then installed release 1.1 (latest as of writing this).

This is a minimal python script to reproduce the issue:

import cv2

cap = cv2.VideoCapture(0) # This prints the error message for the first time
cap.set(cv2.CAP_PROP_FRAME_WIDTH, float(320)) # No error
cap.set(cv2.CAP_PROP_FRAME_HEIGHT, float(240)) # Second time
cap.set(cv2.CAP_PROP_FPS, float(187)) # Third time
cap.release()

Additional Information:
OS: Windows 10
Python version: 3.10.11
OpenCV version: 4.9.0.80
LibusbK version: 3.1.0.0

Do you have found a solution for this? Iam also interested in OpenCV using 320x240 resolution at the highest fps. Does it work on windows 11?

I'll buy this camera for now hopeing that it works
