[experimental] doesn't show the camera I want..

[b3ck]

I'm using the experimental branch so I could choose the camera I wanted (OBS Virtual Camera) which is (2) but it only shows "Camera 0", so I made a test script and I was able to pull my OBS Virtual Camera using 'matplotlib',

It shows up like this:

So I know it's possible, is there a way to force 'deep-live-cam' to use "Camera (2)" ?

I did another test with this code and it worked:

import cv2

cap = cv2.VideoCapture(2)

if not (cap.isOpened()):
    print("Could not open video device")

while True:
    ret, frame = cap.read()
    cv2.imshow("Live", frame)
    cv2.waitKey(1)

cv2.destroyAllWindows()
cap.release()

But still unable to get 'deep-live-cam' working with it.

got it working, just changed line 322 in ui.py

cap = cv2.VideoCapture(camera_index)

to

cap = cv2.VideoCapture(2)

@b3ck there is no line 322 in ui.py https://github.com/hacksider/Deep-Live-Cam/blob/main/modules/ui.py
