-.Sh NAME
-.Nm fwcontrol
-.Nd FireWire control utility
-.Sh SYNOPSIS
-.Nm
-.Op Fl u Ar bus_num
-.Op Fl prt
-.Op Fl c Ar node
-.Op Fl d Ar node
-.Op Fl o Ar node
-.Op Fl s Ar node
-.Op Fl l Ar file
-.Op Fl f Ar node
-.Op Fl g Ar gap_count
-.Op Fl b Ar pri_req
-.Op Fl M Ar mode
-.Op Fl R Ar filename
-.Op Fl S Ar filename
-.Op Fl m Ar EUI64 | hostname
-.Sh DESCRIPTION
-The
-.Nm
-utility is designed to provide a way for users to access and control the
-.Fx
-FireWire subsystem.
-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
-.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.

-- 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).
