This package contains examples for accessing v4l2 from Haskell:

v4l2-capture - dumps frames from a video device to stdout:

$  v4l2-capture |
y4mscaler -v0 -I ilace=none -I sar=1/1 -O chromass=420mpeg2 |
mplayer -demuxer y4m - -vo x11

Currently low-level imperative code; but a mid-level v4l2 library is planned which will make it less horrific.
