python 2 cameras under usb hub
Hi everyone,
I'm doing some tests and I read that the function to get frames from cameras (cv2.videoCapture) has as parameter the index of the device. If you put '-1' you give the code the permission to get frames from the first accessible camera (in my case, my notebook's webcam) and you can put 0 if you have only one.
I'd like to develop with 2 cameras - and as I have only 1 usb port in my notebook - I broke the others 2 - I'm trying to make it run under an USB HUB.
via lsusb I can identify the device index but I can't access the second camera in my python-opencv script...
Does anyone know to solve the problem or what is the best method to work with 2 external cameras ?
Tks for your attention.. =)))
try with 0 for the 1st one , and 1 for the 2nd cam.
but again, both on the same usb hub are a problem, as the IO rate is barely enough for one camera.
