Without options, .Nm will output a list of devices that are/were connected to the bus. .Pp The following options are available: .Bl -tag -width indent .It Fl u Ar bus_num Specify the FireWire bus number to be operated on. The default is bus 0. .It Fl r Initiate bus reset. .It Fl t Show the topology map. .It Fl p Dump PHY registers. .It Fl c Ar node Show the configuration ROM on the node. .It Fl d Ar node Hex dump of the configuration ROM. .It Fl o Ar node Send a link-on PHY packet to the node. .It Fl s Ar node Write to the .Dv RESET_START register on the node. .It Fl l Ar file Load hex dump file of the configuration ROM and parse it. .It Fl f Ar node Force specified .Ar node to be the root node on the next bus reset by sending a PHY config packet. Valid values are 0 - 63. .It Fl g Ar gap_count Broadcast new .Ar gap_count by sending a PHY_config packet. By default this value is 63 on all nodes. Valid values are 0 - 63. .It Fl i Ar pri_req Set the .Dv PRIORITY_BUDGET register on all supported nodes. .It Fl M Ar mode Explicitly specify either .Ar dv or .Ar mpeg mode for the incoming stream. Only meaningful in case of and must precede the .Fl R option. If not specified, the program will try to guess. In case of .Dq format 0x20 error, try to force the .Dq mpeg mode. .It Fl R Ar filename Receive DV or MPEG TS stream and dump it to a file. Use ^C to stop the receiving. Some DV cameras seem not to send the stream if a bus manager exists. If it is impossible to get the stream, try the following commands: .Bd -literal -offset indent sysctl hw.firewire.try_bmr=0 fwcontrol -r .Ed .Pp The resulting file contains raw DV data excluding isochronous header and CIP header. It can be handled by .Nm libdv in the .Fx Ports Collection. Resulting MPEG TS stream can be played and sent over a network using the VideoLAN .Nm vlc tool in the .Fx Ports Collection. The stream can be piped directly to .Nm vlc, see .Sx EXAMPLES . .It Fl S Ar filename Send a DV file as isochronous stream. .It Fl m Ar EUI64 | hostname Set default fwmem target. Hostname will be converted to EUI64 using .Xr eui64 5 . .El .Sh FILES .Bl -tag -width "Pa /dev/fw0.0" .It Pa /dev/fw0.0 .El .Sh EXAMPLES Each DV frame has a fixed size and it is easy to edit the frame order. .Pp .Dl "fwcontrol -R original.dv" .Pp Receive a DV stream with DV camera attached. .Pp .Dl "dd if=original.dv of=first.dv bs=120000 count=30" .Pp Get first 30 frames(NTSC). .Pp .Dl "dd if=original.dv of=second.dv bs=120000 skip=30 count=30" .Pp Get second 30 frames(NTSC). .Pp .Dl "cat second.dv first.dv | fwcontrol -S /dev/stdin" .Pp Swap first and second 30 frames and send them to DV recorder. .Pp For PAL, replace .Dq Li bs=120000 with .Dq Li bs=144000 . .Pp .Dl "fwcontrol -R file.m2t" .Pp Receive an MPEG TS stream from a camera producing MPEG transport stream. This has been tested with SONY HDR-FX1E camera that produces HD MPEG-2 stream at 25 Mbps bandwidth. .Pp To send the stream from the camera over the network using TCP (which surprisingly works better with vlc), you can use .Dl "fwcontrol -R - | nc 192.168.10.11 9000" with .Nm netcat from ports and to receive the stream, use .Dl nc -l -p 9000 | vlc - .Pp To netcast via UDP, you need to use .Nm buffer program from ports, since vlc is not fast enough to read UDP packets from buffers and thus it experiences dropouts when run directly. The sending side can use .Dl "fwcontrol -R - | nc 192.168.10.11 9000" and to receive the stream, use .Dl nc -l -u -p 9000 | buffer -s 10k -b 1000 -m 20m -p 5 | vlc - .Pp For more information on how to work with .Nm vlc see its docs. .Sh SEE ALSO .Xr mplayer 1 , .Xr vlc 1 , .Xr firewire 4 , .Xr fwe 4 , .Xr fwip 4 , .Xr fwohci 4 , .Xr sbp 4 .Sh HISTORY The .Nm utility first appeared in .Fx 5.0 . .Sh AUTHORS .An Hidetoshi Shimokawa Aq Mt simokawa@FreeBSD.org .An Petr Holub Aq Mt hopet@ics.muni.cz (MPEG TS mode) .Sh BUGS This utility is still under development and provided for debugging purposes. Especially MPEG TS reception support is very rudimental and supports only high-bandwidth MPEG-2 streams (fn field in CIP header equals 3).
