I agree. For win32, besides of DirectShow, there is the simple old VfW 
input. I think it's still working and it has a wrapper for DirectShow. 
For OSX, the video capture is in the commercial version of Quicktime.

But there are incompatible hardwares with their own interface (for 
example, BMD DeckLink). So perhaps a raw input through a fifo (named 
pipe) is still a good option.
