32 .Nd FireWire control utility
48 .Op Fl m Ar EUI64 | hostname
52 utility is designed to provide a way for users to access and control the
57 will output a list of devices that are/were connected to the bus.
59 The following options are available:
60 .Bl -tag -width indent
62 Specify the FireWire bus number to be operated on.
66 Show the topology map.
70 Show the configuration ROM on the node.
72 Hex dump of the configuration ROM.
74 Send a link-on PHY packet to the node.
80 Load hex dump file of the configuration ROM and parse it.
84 to be the root node on the next bus reset.
92 register on all supported nodes.
94 Explicitly specify either
98 mode for the incoming stream.
99 Only meaningful in case of and must precede the
101 option. If not specified, the program will try to guess. If you get
102 an error complaining about "format 0x20", try to force the "mpeg" mode.
104 Receive DV or MPEG TS stream and dump it to a file.
105 Use Ctrl-C to stop the receiving.
106 Some DV cameras seem not to send the stream if a bus manager exists.
107 If you cannot get the stream, try the following commands:
108 .Bd -literal -offset indent
109 sysctl hw.firewire.try_bmr=0
113 The resulting file contains raw DV data excluding isochronous header
119 Ports Collection. Resulting MPEG TS stream can be played and sent over a
120 network using the VideoLAN
124 Ports Collection. The stream can be piped directly to
128 Send a DV file as isochronous stream.
129 .It Fl m Ar EUI64 | hostname
130 Set default fwmem target.
131 Hostname will be converted to EUI64 using
139 Each DV frame has a fixed size and it is easy to edit the frame order.
141 .Dl "fwcontrol -R original.dv"
143 Receive a DV stream with DV camera attached.
145 .Dl "dd if=original.dv of=first.dv bs=120000 count=30"
147 Get first 30 frames(NTSC).
149 .Dl "dd if=original.dv of=second.dv bs=120000 skip=30 count=30"
151 Get second 30 frames(NTSC).
153 .Dl "cat second.dv first.dv | fwcontrol -S /dev/stdin"
155 Swap first and second 30 frames and send them to DV recorder.
162 .Dl "fwcontrol -R file.m2t
164 Receive an MPEG TS stream from a camera producing MPEG transport stream. This
165 has been tested with SONY HDR-FX1E camera that produces HD MPEG-2 stream at
168 To send the stream from the camera over the network using TCP (which supprisingly works better with vlc), you can use
169 .Dl "fwcontrol -R - | nc 192.168.10.11 9000
172 from ports and to receive the stream, use
173 .Dl nc -l -p 9000 | vlc -
175 To netcast via UDP, you need to use
177 program from ports, since vlc is not fast enough to read UDP packets from
178 buffers and thus it experiences dropouts when run directly. The sending side
180 .Dl "fwcontrol -R - | nc 192.168.10.11 9000
181 and to receive the stream, use
182 .Dl nc -l -u -p 9000 | buffer -s 10k -b 1000 -m 20m -p 5 | vlc -

206 This utility is still under development and provided for debugging purposes.
207 Especially MPEG TS reception support is very rudimental and supports only
208 high-bandwidth MPEG-2 streams (fn field in CIP header equals 3).
