|
.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.
|
|
.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 g Ar gap_count
|
|
Broadcast
|
|
.Ar gap_count
|
|
by phy_config packet.
|
|
.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. If you get
|
|
an error complaining about "format 0x20", try to force the "mpeg" mode.
|
|
.It Fl R Ar filename
|
|
Receive DV or MPEG TS 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:
|
|
.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 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 .

.Sh FILES
|

.Bl -tag

|
|
.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 supprisingly 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

|
|
.Nm vlc

|
see its docs.

|
utility first appeared in
|
|

- 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).
