About

Vcap aims to provide a concise API for working with cameras and other video capture devices that have drivers implementing the V4L2 specification. It is built on top of the libv4l userspace library (the only dependency) which provides seamless decoding for a variety of formats.

Vcap provides simple, low-level access to device controls and formats, enabling applications to make easy use of the full range of functionality provided by V4L2.

You can find the V4L2 documentation here: https://www.kernel.org/doc/html/v4.8/media/uapi/v4l/v4l2.html
