windows video capture card driver source contains LGPLv2 header file - can I port?

["erpo41@gmail.com" <erpo41@gmail.com>]

Hi all,

I am writing because I have a video capture card based on the MV9200
chip, which currently does not have a Linux driver, and I would like
to remedy that situation.

I'll bet you can guess how responsive the company behind the MV9200
has been when asked for Linux drivers or hardware documentation.

I googled for a Windows driver, and the archive I found contained the
binary Windows driver AND its source code! I couldn't believe my luck.

Now I'm not sure how to proceed because I'm not sure of the copyright
status of the code, and I don't know if that even matters. I grepped
through the source code for 'copyright' and found three instances:

1. The .rc file for the accompanying windows application (as distinct
from the driver) contains a "Copyright (C) 2007" string.
2. The .inf file for the driver contains a "Copyright (c) 1991-2004
VastVision Corporation" string.
3. The header file Command.h in the driver source code contains a
"Copyright (C) 2000 - 2002 by Eduardo Jos?Tagle" string.

The final one intrigued me. The beginning of that file contains the
following comment:

/*
        Command.hpp: Part of the WDM Video Capture Driver for Bt848
based video capture cards

What are my options for creating a Linux driver for this hardware?

Thank you,
