Opencv2 and SDK examples capturing Vive Pro camera

Hi,

I have been trying the example:

leapmotion/leapuvc/blob/master/Python/minimumExample.py

import numpy as np        # `pip install numpy`
import cv2                # `pip install opencv-python`
import leapuvc            #  Ensure leapuvc.py is in this folder

# Start the Leap Capture Thread
leap = leapuvc.leapImageThread()
leap.start()

# Capture images until 'q' is pressed
while((not (cv2.waitKey(1) & 0xFF == ord('q'))) and leap.running):
    newFrame, leftRightImage = leap.read()
    if(newFrame):
        # Display the raw frame
        cv2.imshow('Frame L', leftRightImage[0])
        cv2.imshow('Frame R', leftRightImage[1])

cv2.destroyAllWindows()

On Windows 10 using my HTC Vive Pro (HVP) and Leap Motion (LM). The LM is on and tracking fine in Unity but when using it via opencv it seems to be grabbing the L/R camera from the HVP. I tried changing the default source to 1 (in leapuvc.py)

So I change the line:

def init(self, source = 1, resolution = (640, 480), timeout=3.0)

But I get

(base) C:\Users\staylor\Documents\Python\leapuvc-master\Python>python minimumExample.py
[ WARN:1] videoio(MSMF): OnReadSample() is called with error status: -1072875772
[ WARN:1] videoio(MSMF): async ReadSample() call is failed with error status: -1072875772
[ WARN:2] videoio(MSMF): can't grab frame. Error: -1072875772
[ WARN:2] videoio(MSMF): can't grab frame. Error: -2147483638
Exiting Leap Image Thread!

Any help would be much appreciated!

Did you manage to solve this?
