34 .Nd FireWire control utility
50 utility is designed to provide a way for users to access and control the
54 will output a list of devices those are/were connected to the bus.
56 .Bl -tag -width indent
60 Show the topology map.
62 Show the configuration ROM on the node.
64 Hex dump of the configuration ROM.
66 Send a link-on phy packet to the node.
68 Write to RESET_START register on the node.
70 Load hex dump file of the configuration ROM and parse it.
72 Broadcast gap_count by phy_config packet.
74 Set PRIORITY_BUDGET register on all supported nodes.
76 Receive DV stream and dump it to a file. Use Ctl-C to stop the receiving.
77 Some DV cameras seem not to send the stream if a bus manager exits.
78 If you cannot get the stream, try the following commands.
79 .Bd -literal -offset indent
80 sysctl hw.firewire.try_bmr=0; fwcontrol -r
83 The resulting file contains raw DV data excluding isochronous header
84 and CIP header. It can be handled by
90 Send a DV file as isochronous stream.
93 .Bl -tag -width indent
97 Each DV frame has fixed size and it is easy to edit those frame order.
98 .Bd -literal -offset indent
99 fwcontrol -R original.dv
103 .Bd -literal -offset indent
104 dd if=original.dv of=first.dv bs=120000 count=30
107 Get first 30 frames(NTSC).
108 .Bd -literal -offset indent
109 dd if=original.dv of=second.dv bs=120000 skip=30 count=30
112 Get second 30 frames(NTSC).
113 .Bd -literal -offset indent
114 cat second.dv first.dv | fwcontrol -S /dev/stdin
117 Swap first and second 30 frames and send them to DV recorder.
119 For PAL, replace 'bs=120000' with 'bs=144000'.
