1 year ago set config.py settings per below and give it a try. Also make sure the resolution for webcam is appropriate for your cam. i suggest start at 320x240
WEBCAM = True # Default= False False=PiCamera True= USB Webcam or RTSP,IP Camera
Web Camera Settings
WEBCAM_SRC = 0 # Default= 0 USB camera device connection number

There seems to be an issue possibly isolated to my inexperience with programming. I for the life of me cannot get the program to run on my usb camera. There is no Pi camera installed just the usb one. No other video devices in v4l2. I have attemted to change the webcam source but do i need to select the device number for it?
