NAME
       webcamd	-- daemon which	provide	access to USB webcam, USB DVB, USB ra-
       dio, USB	input, USB tablet and more devices

SYNOPSIS
       webcamd [-B] [-D	<host:port:ndev>] [-L  <host:port:ndev>]  [-U  <user>]
	       [-G    <group>]	  [-M	 <matchindex>]	  [-N	 <devicename>]
	       [-S     <deviceserialnumber>]	 [-d	  [ugen]<unit>.<addr>]
	       [-i  <interface	or  client number>] [-v	<video device number>]
	       [-c <devname>] [-m <parameter>=<value>] [-r] [-l] [-s] [-h]

DESCRIPTION
       webcamd is a daemon that	enables	the use	of hundreds of	different  USB
       webcam,	USB DVB, USB radio, USB	input, USB tablet and more devices un-
       der the FreeBSD operating system.  The webcamd daemon  is  basically  a
       port of Linux USB device	drivers	into userspace in FreeBSD.

       webcamd	requires  the  cuse(3) kernel module.  To load the driver as a
       module at boot time, place the following	line in	loader.conf(5):

	      cuse_load="YES"

       To start	webcamd	automatically at system	startup, place	the  following
       line in rc.conf(5):

	    webcamd_enable="YES"

       Once  webcamd  is  running, supported USB devices will be available for
       use by other applications.

       The following options are available:

       -B      Run the daemon in background mode.

       -d      Specify the <unit>.<addr> of the	USB device to use.   This  op-
	       tion can	be combined with -N and	-S options.

       -f      If the device requires a	firmware file, specify the path	to the
	       firmware.  The default firmware path is /boot/modules.

       -h      Print help text showing available options.

       -m      Specify	the  value  of a parameter.  Note that escaping	is not
	       supported for strings.

       -i      Specify the interface number to use.

       -r      Do not set realtime priority.

       -S      Attach to device	matching the given serial number.  This	option
	       can be combined with -d and -N options.

       -M      Specify the match index when using -S and -N options.  This op-
	       tion is useful when multiple USB	devices	share the same	serial
	       and  devicename	to  be	able  to distinguish them.  Default is
	       zero.

       -N      Attach to device	matching the given device name.	  This	option
	       can be combined with -d and -S options.

       -l      List  the available USB devices and the needed command line for
	       binding to the given device.

       -s      Show available parameters.

       -v      Specify the video device	number.

       -c      Create device of	specified type.	Valid values: v4l2loopback For
	       multiple	v4l2loopback devices, specify

		     -m	v4l2loopback.devices=2

       -U      Set the user identification for all character  devices  created
	       by webcamd.  Default value: webcamd

       -G      Set  the	group identification for all character devices created
	       by webcamd.  Default value: webcamd

       -D      Enable vTuner client support.  Connect to one  or  more	remote
	       DVB  device  instead  of	 using USB.  The vTuner	protocol needs
	       eight ports for normal operation	which are  allocated  back  to
	       back.   One  port  for control communication and	the other port
	       for data	communication.	NOTE: If you want  to  start  multiple
	       vTuner  clients	in the background by use of the	-B option, you
	       need to supply a	unique interface number	for each client	 using
	       th -i option.

       -L      Enable vTuner server support.  Make the DVB device available on
	       TCP/IP  instead of cuse(3).  If the ndev	parameter is negative,
	       all present DVB devices are mapped to TCP/IP.   Else  only  the
	       given  number  of  DVB devices are mapped.  The vTuner protocol
	       needs eight ports for normal operation which are	allocated back
	       to back.	 One port for control communication and	the other port
	       for data	communication.

EXAMPLES
       With the	USB device connected, determine	the [ugen]<unit>.<addr>	values
       using usbconfig(8):

	     usbconfig
	     ugen7.2: <product 0x0991 vendor 0x046d> at	usbus7,	cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON

       Create a	vTuner client:

	     webcamd -D	127.0.0.1:5100:1:2

       Create a	vTuner server:

	     webcamd -L	127.0.0.1:5100:-1

NOTES
       All character devices are created using the 0660	mode which  gives  the
       user and	group read and write permissions.
