See fwcontrol(8) I use it all the time to make DVDs out of my DV-tapes. Connect your DV-camera to the firewire port, start "fwcontrol -R video.dv", and press play on your camera. Your screen will start to fill up with numbers. When you are done, press stop and then ^c fwcontrol. You can also use fwcontrol to send a dv-stream back into your camera. You could use multimedia/transcode to convert the raw dv-stream into something more useful (and less space consuming). > Another related question is if FreeBSD has any libraries like Linux's > libdv and libavc. If not, then would it be good to try and port them or > provide a compatible api for supporting video? See multimedia/libdv in the ports collection. Cheers, Svein Halvor
