32 .Nd FireWire control utility
47 .Op Fl m Ar EUI64 | hostname
51 utility is designed to provide a way for users to access and control the
56 will output a list of devices that are/were connected to the bus.
58 The following options are available:
59 .Bl -tag -width indent
61 Specify the FireWire bus number to be operated on.
65 Show the topology map.
69 Show the configuration ROM on the node.
71 Hex dump of the configuration ROM.
73 Send a link-on PHY packet to the node.
79 Load hex dump file of the configuration ROM and parse it.
87 register on all supported nodes.
89 Explicitly specify either
93 mode for the incoming stream.
94 Only meaningful in case of and must precede the
96 option. If not specified, the program will try to guess. If you get
97 an error complaining about "format 0x20", try to force the "mpeg" mode.
99 Receive DV or MPEG TS stream and dump it to a file.
100 Use Ctrl-C to stop the receiving.
101 Some DV cameras seem not to send the stream if a bus manager exits.
102 If you cannot get the stream, try the following commands:
103 .Bd -literal -offset indent
104 sysctl hw.firewire.try_bmr=0
108 The resulting file contains raw DV data excluding isochronous header
114 Ports Collection. Resulting MPEG TS stream can be played and sent over a
115 network using the VideoLAN
119 Ports Collection. The stream can be piped directly to
123 Send a DV file as isochronous stream.
124 .It Fl m Ar EUI64 | hostname
125 Set default fwmem target.
126 Hostname will be converted to EUI64 using
134 Each DV frame has a fixed size and it is easy to edit the frame order.
136 .Dl "fwcontrol -R original.dv"
138 Receive a DV stream with DV camera attached.
140 .Dl "dd if=original.dv of=first.dv bs=120000 count=30"
142 Get first 30 frames(NTSC).
144 .Dl "dd if=original.dv of=second.dv bs=120000 skip=30 count=30"
146 Get second 30 frames(NTSC).
148 .Dl "cat second.dv first.dv | fwcontrol -S /dev/stdin"
150 Swap first and second 30 frames and send them to DV recorder.
157 .Dl "fwcontrol -R file.m2t
159 Receive an MPEG TS stream from a camera producing MPEG transport stream. This
160 has been tested with SONY HDR-FX1E camera that produces HD MPEG-2 stream at
163 To send the stream from the camera over the network using TCP (which supprisingly works better with vlc), you can use
164 .Dl "fwcontrol -R - | nc 192.168.10.11 9000
167 from ports and to receive the stream, use
168 .Dl nc -l -p 9000 | vlc -
170 To netcast via UDP, you need to use
172 program from ports, since vlc is not fast enough to read UDP packets from
173 buffers and thus it experiences dropouts when run directly. The sending side
175 .Dl "fwcontrol -R - | nc 192.168.10.11 9000
176 and to receive the stream, use
177 .Dl nc -l -u -p 9000 | buffer -s 10k -b 1000 -m 20m -p 5 | vlc -

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