BSD video capture (again!)

Hey -- sounds good to me!  I'm looking forward to the day I can
video conference from my laptop without resorting to another OS.

I agree -- it would be very nice to have compatibility with all
those programs that can take advantage of the v4l interface under
Linux.  Perhaps a clean framework that can be accessed directly for
a purely *bsd solution but also a compatibility layer for aps
developed for Linux?

Whatever the situation I'd like to be involved.

Something interesting came to my attention today when I was
searching for any updated status on this stuff.  I had originally
started a thread asking if a compatibility layer could be introduced
over the top of the firewire dv capture mechanism more easily than
creating one for usb capture devices from scratch.  Have a look at
this:

http://www.rmatsumoto.org/camera/dc1394-ohphone.html

I was intrigued to see this.  libavc1394 appears to be based upon
libraw1394 which is dependent on the linux architecture.  Since
gnomemeeting already supports this, how hard would it be to write
our own "libraw1394" that libavc1394 could depend on?  (Note: I
haven't really looked at it in depth -- this is just my impression)
At first glance it would appear that the necessary functionality is
already available from fwcontrol (namely a raw dv stream)...
