videodev2
Python ctypes bindings for Video4Linux2 (V4L2) API
Overview
This package provides Python ctypes bindings for the Linux Video4Linux2 (V4L2) API, automatically generated from the videodev2.h header file. It includes all V4L2 structures, enums, constants, and IOCTL definitions needed for video device programming.
Installation
pip install videodev2
Usage
import videodev2
# Access V4L2 symbols through the videodev2 module
from videodev2 import videodev2
# Example: Query device capabilities
import fcntl
# Open video device
fd = open('/dev/video0', 'rb+', buffering=0)
# Query capabilities
cap = videodev2.v4l2_capability()
fcntl.ioctl(fd, videodev2.VIDIOC_QUERYCAP, cap)
print(f"Driver: {cap.driver.decode()}")
print(f"Card: {cap.card.decode()}")
# Set format
fmt = videodev2.v4l2_format()
fmt.type = videodev2.V4L2_BUF_TYPE_VIDEO_CAPTURE
fmt.fmt.pix.width = 640
fmt.fmt.pix.height = 480
fmt.fmt.pix.pixelformat = videodev2.v4l2_fourcc('Y', 'U', 'Y', 'V')
fcntl.ioctl(fd, videodev2.VIDIOC_S_FMT, fmt)
Features
- Complete V4L2 API coverage
- All structures, enums, and constants
- IOCTL definitions
- Helper functions (e.g.,
v4l2_fourcc) - Compatible with Python 3.6+
