That's actually format/videodev.c, but it isn't "v4l" itself, it's "v4l support
for gridflow". "v4l" refers to two protocols used by apps and drivers to talk
to each other.

Configure your camera as you would normally do on Linux. Then, if your driver
is V4L1-compatible, chances are that it will work on GridFlow.
If ever it's a V4L2-only driver, then try the trick Johannes talked about and
don't forget to tell us whether it worked and if not, what the problem was!

cameras, video files, picture files, ... though you can also generate video
from scratch as well (no source). for the cameras themselves, gridflow supports
V4L1 *and* FireWire-DC on Linux, and supports only the QuickTime camera
interface on OSX. Chances are that I'm adding V4L2 soon. I forgot to mention
FireWire-DC before (aka DC1394).
