Linux video device library.

This library provides a (hopefully) convenient and high-level wrapper around the V4L2 ioctls, and allows accessing video devices (capture cards, webcams, etc.) on Linux systems.

The main entry points to the library are list, for enumerating all V4L2 devices (and opening one of them by name), and Device::open, for opening a specific path.

V4L2 userspace library

This is a Linux Video library that provides access to V4L2 devices. It directly calls the V4L2 ioctls without depending on libv4l or other C code.

The V4L2 userspace API is documented in the following places:
