VFW is old and deprecated, it's cruft from the 16 bit Windows 3.x days.
DirectShow is the modern replacement.

You can use the full Win32 API with gcc; this is what the w32api package
provides. But do note that for the purposes of a Cygwin program (as
opposed to a Mingw one) you should do things in a Posix way whenever
possible -- this means using open() instead of CreateFile(),
fork()/exec() or spawn() instead of CreateProcess(), pthreads instead of
CreateThread(), and so on.If you want to write a pure windows app and do
everything in the Win32 API way then you should use Mingw.
