OpenCV Camera Error on M1 MacBook Pro

2021-11-01 10:16:09.596 Python[45041:1449940] Error loading /Library/CoreMediaIO/Plug-Ins/DAL/XSplit VCam.plugin/Contents/MacOS/XSplit VCam: dlopen(/Library/CoreMediaIO/Plug-Ins/DAL/XSplit VCam.plugin/Contents/MacOS/XSplit VCam, 0x0106): tried: '/Library/CoreMediaIO/Plug-Ins/DAL/XSplit VCam.plugin/Contents/MacOS/XSplit VCam' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e')), '/usr/lib/XSplit VCam' (no such file) OpenCV: out device of bound (0-0): 1 OpenCV: camera failed to properly initialize!

I'm really worried- How should this be fixed?

XSplit VCam incompatible architecture

Wrong bug tracker.

Is there any way to get this working on the M1 Mac?

Running into same error, without using other libraries. Here the example to replicate:

import cv2 as cv

cap = cv.VideoCapture(-1)

if not cap.isOpened():
  print("Cannot open camera")
  exit()

while True:
  print('start reading frames')

  # Capture frame-by-frame
  ret, frame = cap.read()

  print("ret", ret)
  print("frame", frame)

  # if frame is read correctly ret is True
  if not ret:
    print("Can't receive frame (stream end?). Exiting ...")
    break

  break

  # Our operations on the frame come here
  # gray = cv.cvtColor(frame, cv.COLOR_BGR2GRAY)
  # Display the resulting frame
  # cv.imshow('frame', gray)
  print("image size:", gray.size)

  if cv.waitKey(1) == ord('q'):
    break

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

outputs
