| -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:
sysctl hw.firewire.try_bmr=0
fwcontrol -r
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). |
|
EXAMPLES
Each DV frame has a fixed size and it is easy to edit the frame order.
"fwcontrol -R original.dv"
Receive stream.
"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".
