Re: [pygame] Camera module roadmap

Hoi,
I have included a timeline for the implementation of the camera module for osx in my gsoc application. You can take a look at that, to get an idea of how long it is going to take to implement.

Hi all,
(esp. Nirav, René and Chelsea)
I am interested in getting involved in the pygame camera module, since
I use it for my stop motion software ToonLoop I am developing with
Tristan Matthews. See http://toonloop.com : and yes, I think ToonLoop
is a great free software to test the pygame.camera module with, if you
don't installing Twisted. Creating a cross-platform application is my
main concern, and I feel like there is a lack of cross-platform C
libraries for having a live camera input. Anyways, Python is the way
to go for such a high-level software like mine. I am not so much of an
expert in C, but I can help with the software architecture.

Mac : So, the Mac version uses the OpenCV wrapper for now ? I have
read on Nirav's blog that py-objective-C wasn't well maintained enough
? Does that mean we will stick with the OpenCV camera wrapper this
summer, Chelsea ? Are there build/install instructions for Mac ? It
seems like the camera API is slightly different between Mac and
GNU/Linux. At the end of this email, I provide two code snippets which
illustrates those differences. It's when we initiate the camera, and
when copying a surface from it to a list of surfaces.

Linux : On GNU/Linux, I am having success with v4l2 inputs. What is
the state of the v4l ones ? Has it been reported to work for some
users ? Any plan to support raw1394 cameras ? (libdc1394) When is it
planned to release a .deb with pygame containing the camera module ?
What is the state of your computer vision tools for Pygame, Nirav ?

Windows : What is the state of the camera module on Windows ? The
vidcap module was reported to be working, (Feb 2009) but will it be
officially part of pygame, or should it be using an other tool/driver
?

Any chances I can make py2app and py2exe applications with
pygame.camera support before the end of the summer ?

Thank you !!
