Dear all
I'm facing an error when trying to create a VideoCapture object (in this code, associated to device "0" -> /dev/video0)
I am running FreeBSD 14. The issue can be reproduced on the current freebsd opencv package (4.6.0), the port and the latest opencv 4.9.0 compiled from sources.
I checked permissions on /dev/video0, status on webcamd and possible hw issues. I tested the camera with jitsi on a browser and it works fine.
PS: When instead of the camera device file I place a file in VideoCapture (eg, cam = cv2.VideoCapture('someclip.mpg') ) works well and it reproduces the video on the frame.
Best,
