jaraco.video is a port of the VideoCapture module in pure Python using ctypes and comtypes.
jaraco.video is maintained by Jason R. Coombs. It is licensed under an MIT-style permissive license.
You can install it with easy_install jaraco.video, or from the mercurial repository with easy_install jaraco.video==dev.
jaraco.video is designed to run on Python 2.5+, including Python 3, and including 32-bit and 64-bit versions of Python.
Although the package currently installs on Python 3, there is currently no supported version of PIL for Python 3, so only raw bitmap data will be available (no JPEG support, etc).
jaraco.video includes a console script "save-frame" which if invoked will locate the first video capture device and attempt to save a frame to disk as "test.jpg".
This example usage can be seen in jaraco.video.capture:save_frame.
