It should be easy to put it back. > The usage of videobuf simplifies a lot the driver logic. That's why it is so small :) > > I think it would be good if gspca could also use videobuf in the future. I think that videobuf is rather complex for handling usually less than 8 buffers (max = 16 in gspca) and it asks for a mutex at irq level. My buffer handling also offers a very small memory overhead...
