I've uploaded the 'v4l2' package to hackage now.

When I initially wrote it last year I had hoped to use it as a base for 
something similar to 'repa-v4l2' and perhaps 'opengl-v4l2' (*).

Alas, I don't have a pressing need to access v4l2 devices at the moment, 
so I don't expect there to be rapid development or even prompt bug fixes 
(unless people provide patches) - if someone more involved than I am at 
present in video devices + Haskell on Linux wants to take over the 
maintainership of these v4l2-related packages, let me know:




(*) I had written some code along those lines, though all I can find at 
the moment is a screenshot (live webcam video, processed to generate an 
overlay and displayed using opengl):
