32 .Nd FireWire control utility
46 .Op Fl m Ar EUI64 | hostname
50 utility is designed to provide a way for users to access and control the
55 will output a list of devices that are/were connected to the bus.
57 The following options are available:
58 .Bl -tag -width indent
60 Specify the FireWire bus number to be operated on.
64 Show the topology map.
68 Show the configuration ROM on the node.
70 Hex dump of the configuration ROM.
72 Send a link-on PHY packet to the node.
78 Load hex dump file of the configuration ROM and parse it.
86 register on all supported nodes.
88 Receive DV stream and dump it to a file.
89 Use Ctrl-C to stop the receiving.
90 Some DV cameras seem not to send the stream if a bus manager exits.
91 If you cannot get the stream, try the following commands:
92 .Bd -literal -offset indent
93 sysctl hw.firewire.try_bmr=0
97 The resulting file contains raw DV data excluding isochronous header
105 Send a DV file as isochronous stream.
106 .It Fl m Ar EUI64 | hostname
107 Set default fwmem target. Hostname will be converted to EUI64 using
111 Each DV frame has a fixed size and it is easy to edit the frame order.
113 .Dl "fwcontrol -R original.dv"
117 .Dl "dd if=original.dv of=first.dv bs=120000 count=30"
119 Get first 30 frames(NTSC).
121 .Dl "dd if=original.dv of=second.dv bs=120000 skip=30 count=30"
123 Get second 30 frames(NTSC).
125 .Dl "cat second.dv first.dv | fwcontrol -S /dev/stdin"
127 Swap first and second 30 frames and send them to DV recorder.
