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.

Reference

The V4L2 userspace API is documented in the following places:

• /usr/include/linux/videodev2.h
• https://kernel.org/doc/html/latest/userspace-api/media/index.html

lib.rs:

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.
