I was compiling the latest version of KDE4 on my box and I noticed it picked up my installed libv4l2. 
The only problem is that you need some patches before everything is compiling :-)

About libv4lX on FreeBSD, please see:


Only USB webcams supported yet.

After installation manually add -lv4lxdrivers to all the libv4l*.pc files!
I will try to get this included into my ulinux distribution soon.

Libs: -L${libdir} -lv4lconvert
Libs: -L${libdir} -lv4lconvert -lv4lxdrivers


Then patch KDE4 like this:
