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)...
