FWCONTROL(8) BSD System Manager's Manual FWCONTROL(8) NAME fwcontrol -- FireWire control utility SYNOPSIS fwcontrol [-rt] [-c node] [-d node] [-l file] [-g gap_count] [-b pri_req] [-R filename] [-S filename] DESCRIPTION The fwcontrol utility is designed to provide a way for users to access and control the FreeBSD FireWire subsystem. Without options, fwcontrol will output a list of devices those are/were connected to the bus. -r Initiate bus reset. -t Show the topology map. -c node Show the configuration ROM on the node. -d node Hex dump of the configuration ROM. -l file Load hex dump file of the configuration ROM and parse it. -g gap_count Broadcast gap_count by phy_config packet. -i pri_req Set PRIORITY_BUDGET register on all supported nodes. -R filename Receive DV stream and dump it to a file. Use Ctl-C to stop the receiving. Some DV cameras seem not to send the stream if a bus manager exits. If you cannot get the stream, try the following commands. sysctl hw.firewire.try_bmr=0; fwcontrol -r The resulting file contains raw DV data excluding isochronus header and CIP header. It can be handled by libdv in the ports collection. -S filename Send a DV file as isochronus stream. EXAMPLES Each DV frame has fixed size and it is easy to edit those frame order. fwcontrol -R original.dv Receive stream. dd if=original.dv of=first.dv bs=120000 count=30 Get first 30 frames(NTSC). dd if=original.dv of=second.dv bs=120000 skip=30 count=30 Get second 30 frames(NTSC). cat second.dv first.dv | fwcontrol -S /dev/stdin Swap first and second 30 frames and send them to DV recorder. For PAL, replace 'bs=120000' with 'bs=144000'. FILES /dev/fw0 SEE ALSO firewire(4), fwohci(4), sbp(4), fwe(4) HISTORY The fwcontrol utility first appeared in FreeBSD 5.0.
