v4l support is not part of mainline FreeBSD, various drivers ship their 
own, please see ports/multimedia/pwcbsd, ports/devel/linux-kmod-compat, 
ports/multimedia/linux-gspca-kmod etc.

Also see here for an app which runs on FreeBSD and uses v4l 1.x to do so:

There are a number of criticisms and issues of v4l 2, however, the level 
of work involved is such that IMHO it is either going to take highly 
motivated individuals with lots of free time, or a compelling business 
case, for this support to appear in FreeBSD.
