WinVDIG is a video digitizer that bridges the gap between QuickTime and Windows capture drivers. WinVDIG creates virtual VDIGs for installed WDM (Windows Driver Model) and VfW (Video for Windows) capture drivers, allowing QuickTime-based applications to capture video using hardware that lacks QuickTime support (a VDIG).MacOS X drivers
IOXperts provide MacOSX native drivers for a large range of USB and FireWire cameras.
Macam by Matthias Krauss is an open-source video digitizer for USB-based cameras on MacOSX. The project initially supported a few Philips models, but it has evolved to cover a range of models from other manufacturers as well.
