A framework for drivers of video cameras, TV tuners etc. The device API for userland processes is commonly called v4l or v4l2 (v4l being deprecated in theory). Drivers written for this framework are normally compiled into the LinuxKernel as Modules. The devices are enumerated by UDev and appear as /dev/video0, /dev/video1 etc.
Also known as V4L.
