If you end up starting from scratch, I'd suggest looking into Xuggler
(http://xuggle.com) as a starting point.
I was recently considering V4L for a java project, but I found that
Xuggler was "better" (unfortunately I really can't remember what the
definition of "better" was in that case...). Xuggler uses FFMPEG,
which (as far as I could tell..) gave it a lot more capabilities than
I'm no expert, and Xuggle may simply not do what you want, but it's
worth a look.
