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 [Module]s. The devices are enumerated by [UDev] and appear as <tt>/dev/video0</tt>, <tt>/dev/video1</tt> etc.

+You must have the <tt>videodev</tt> [Module] loaded as well.
+
+Some applications require a specific device name e.g. <tt>/dev/video</tt>. If this is the case then use mknod(1) to create a device entry or ln(1) to link one if it already exists. I suspect this could also be done with [UDev] as well but don't know much about that.
Also known as [V4L].
