|-u bus_num |
| || Specify the FireWire bus number to be operated on. |
|-r || Initiate bus reset. |
|-t || Show the topology map. |
|-p || Dump PHY registers. |
|-c node |
| || Show the configuration ROM on the node. |
|-d node |
| || Hex dump of the configuration ROM. |
|-o node |
| || Send a link-on PHY packet to the node. |
|-s node |
| || Write to the RESET_START register on the node. |
|-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 the PRIORITY_BUDGET register on all supported nodes. |
|-R filename |
| || Receive DV stream and dump it to a file. Use Ctrl-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: |
The resulting file contains raw DV data excluding isochronous header and CIP header. It can be handled by libdv in the
.Fx Ports Collection.
|-S filename |
| || Send a DV file as isochronous stream. |
|-m EUI64 | hostname |
| || Set default fwmem target. Hostname will be converted to EUI64 using eui64(5). |
Each DV frame has a fixed size and it is easy to edit the frame order.
"fwcontrol -R original.dv"
"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".
