Hello Cafe,
since I haven't found anything like that, I wrote a small library [1] to read from a webcam in Haskell, using V4L on Linux. It uses the v4l2 package and repa for images. Is anyone interested in contributing to that, or giving some hints on how it could be made faster (I am not sure if I use repa correctly for best performance at all times), or just in emitting any other constructive comments? If yes, please give me a shout.
PS I would put the whole thing on hackage, but my cabal currently doesn't want to do an sdist.
I've downloaded and built this. I had to also download Claude Heiland-Allen's v4l2 source from gitorious, as that package does not seem to be on hackage (though his other related packages are). I guess your package won't build on hackage until v4l2 is uploaded ... In any case I was able to run "cabal sdist". It gave a warning about no Setup.hs file; I've sent you a pull request which adds this, and also relaxes some library constraints in the cabal file. Two questions: * you've set the license to GPL3, but the C libraries it builds on are LGPL-2.1 (libv4l2) and repa and the haskell bindings it uses are BSD3. GPL3 seems a bit restrictive for a library. * the name hsimage is fairly broad, I'd suggest a simpler name like repa-v4l2. If you want to support other device APIs or add other software image processing routines, I think it would make more sense to put those in separate packages. cheers, Conrad.
