It is a warning message and not an error. It says that Open CV tried to use V4L library to open camera, but none is available.
Are you using raspberry pi camera module? Just an FYI, Open CV do not have a video capture backend that is compatible with raspberry pi camera module. You won't be able to create a VideoCapture from Open CV using the RP camera module.
