Video4Linux
From Wikipedia, the free encyclopedia
Video4linux or V4L is a video capture API for Linux. Several USB webcams, TV tuners, and other devices are supported. Video4Linux is closely integrated with the Linux kernel.
V4L is in its second version. The original V4L was introduced late into the 2.1.X development cycle of the Linux kernel. Video4Linux2 fixed some design bugs and started appearing in the 2.5.X kernels.
