A simple, libv4l2-based frames capture library. The pyv4l2 module based PyV4L2Camera development, I removed the v4lconvert_convert part of the code, the most original data to return the device. PyV4L2Camera module in https://gitlab.com/radish/PyV4L2Camera ,Thank you Dominik Pieczyński.
Libv4l2 is packaged by various distributions:
# apt-get install libv4l-dev
# dnf install libv4l-devel
# pacman -S v4l-utils
To install pyv4l2:
$ pip install pyv4l2
pyv4l2 is only compatible with Python 3.
from pyv4l2.frame import Frame
from pyv4l2.control import Control
frame = Frame('/dev/video0')
frame_data = frame.get_frame()
control = Control("/dev/video0")
control.get_controls()
control.get_control_value(9963776)
control.set_control_value(9963776, 8)
