I'm not sure I understand the distinction. For example, if I pipeline a
series of camera images
at the desired frame rate into a component that converts a sequences of
frames into a video
stream, then I achieve the desired result right?
I imagine that the video streaming component would surely be very
portable, but the video
capture would tend to be O/S and hardware specific.
Maybe what the world needs is a set of webcam drivers wrapped up into a
independent PIL compatible python module, that could then be wrapped
into a Kamelia
component. Anyone else interested in such a project? I can't believe
such a thing doesn't
