# 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
```bash
pip install videodev2
```
## Usage
```python
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+
