We are using a USB chip for interfacing our video camera. We are able to get
it running. However, we want to customer video format so that it can runs
higher frame rate at black and white mode compare to color mode. The way we
want to do it is to input the chip with Y information at U and V bytes. The
chip Vendor only provides us a driver filter to play with and tells that our
idea is not possible. But I wonder?

My question are how to find out what layer this filter is within the driver,
is it possible that I can change the video format (re-assemble the video
data and change the size) in the filter do not mater what level it is in.

Anyone there has this experience give me some advice? Thanks you very very
much in advance!!!! Please help.
