Raspberry 3 Video4Linux

I have installed Jessie-Lite and OF on a RPI 3
I am using SSH but with an HDMI monitor and camera connected to the Pi.
The simple OF examples work, raspi-still works.
However when I try any example that uses the videoGrabber in OF it fails because it cannot find video4linux when it enumerates udev

I have tried installing uv4l but no luck. Anyone have any idea on getting v4l working on the `rpi 3? I have Googled but the discussions are all a few years old.
Maybe I have to install the full Jessie.
