Hackage and Google turn up nothing¹, so I am asking here; has anyone written a v4l library for Haskell?
I have been reading the v4l documentation² and I am ready to implement a Haskell interface for webcams, but it would be a waste of effort if someone's already got one knocking about. I could hack on theirs!
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 V4L. I'm no expert, and Xuggle may simply not do what you want, but it's worth a look. --Rogan
Cheers!

¹ In fact, the only Google result is a posting to this mailing list asking if there is a v4l library to which the single response is "no, write an FFI interface". ² http://pages.cpsc.ucalgary.ca/~sayles/VFL_HowTo/ and http://pages.cpsc.ucalgary.ca/~sayles/VFL_HowTo/Video4LinuxAPI.html
