.SH NAME
videohubctrl - Blackmagic Design Videohub SDI router control
.SH SYNOPSIS
.B videohubctrl --host <host> \fI..other options..\fR
.SH DESCRIPTION
videohubctrl implements the simple text based network protocol for
controlling Blackmagic Design Videohub SDI router devices. The
program is tested with Blackmagic Design Micro Videohub 16x16
router and probably will work with other Videohub models.

videohubctrl currently displays and can configure:
  - Video input port names
  - Video output port names
  - Video output routing
  - Video output locking
.SH MAIN OPTIONS
.PP
.TP
\fB\-h\fR, \fB\-\-host\fR <host>
Set the device host name. It can be an IP address or host name. You
can set \fBVIDEOHUB_HOST\fR environment variable instead of using
this option.
.TP
\fB\-p\fR, \fB\-\-port\fR <port>
Set the device port. You can set \fBVIDEOHUB_PORT\fR environment
variable instead of using this option. The default port is \fB9990\fR.
.SH COMMANDS
.PP
.TP
\fB\-i\fR, \fB\-\-info\fR
Show full device info. This is the default command if none is set.
The command shows the equivalent of running all \-\-list-XXX commands.
.TP
\fB\-m\fR, \fB\-\-monitor\fR
Display the Videohub configuration and updates it in real-time as it
is changed. The monitor shows config changes immediately as they happen.
The device is not being polled, instead the videohub protocol is designed
in such way that every client receives changes on the fly.
.TP
\fB\-b\fR, \fB\-\-backup\fR
Show the command line that will restore the device to it's configuration.
.TP
\fB\-\-list\-device\fR
Display main device info including model, number of ports, etc.
.TP
\fB\-\-list\-vinputs\fR
Display device video inputs and their names.
.TP
\fB\-\-list\-voutputs\fR
Display device video outputs, their names, locking status and which
input is routed to a given output. There are two locking statuses:
  L - The port is locked by another IP address (user)
  O - The port is locked by me (from my IP address)
.SH VIDEO INPUT/OUTPUT CONFIGURATION
.PP
Everywhere where port number is accepted, you can use the port
number or the port name.
.TP
\fB\-\-vi\-name\fR <in_X> <name>
Set video input port X name.
.TP
\fB\-\-vo\-name\fR <out_X> <name>
Set video output port X name.
.TP
\fB\-\-vo\-route\fR <out_X> <in_Y>
Connect video output X to video input Y.
.TP
\fB\-\-vo\-lock\fR <out_X>
Lock output port X.
.TP
\fB\-\-vo\-unlock\fR <out_X>
Unlock output port X. If the port is locked by somebody else the
port would be forcefully unlocked.
.SH MISC OPTIONS
.PP
.TP
\fB\-d\fR, \fB\-\-debug\fR
Enable debugging output. Use this option more times to increase
the verbosity.
.TP
\fB\-q\fR, \fB\-\-quiet\fR
Suppress warnings about unsupported commands.
.TP
\fB\-V\fR, \fB\-\-version\fR
Show program name and version.
.TP
\fB\-H\fR, \fB\-\-help\fR
Show program usage text.
.SH ENVIRONMENT VARIABLES
.PP
.TP
\fBVIDEOHUB_HOST\fR
Set the device host name.
.TP
\fBVIDEOHUB_PORT\fR
Set the device port.
.SH EXAMPLES
.PP
To get a quick start here are some example command lines.

.nf
 # Rename video output
   videohubctrl -h sdi --vo-name 8 "Output 8 - test"
   videohubctrl -h sdi --vo-name "Output 8 - test" "Output 8"

 # Rename video input
   videohubctrl -h sdi --vi-name 4 "Windows 4 HD"
   videohubctrl -h sdi --vi-name "Windows 4 HD" "CPlay4"

 # Lock and then unlock output 16 (unlock assumes that the port is
 # named Output 16). The host name is set via env variable.
   export VIDEOHUB_HOST=sdi
   videohubctrl --vo-lock 16
   videohubctrl --vo-unlock "Output 16"

 # Set two outputs to receive from the same input using port names
   videohubctrl -h sdi --vo-route "Output 8" "Windows 4 HD"
   videohubctrl -h sdi --vo-route "Output 7" "Windows 4 HD"

 # Run several commands at once
 # Rename video input 11 and 12
 # Rename video output 5,
 # Set output 5 to receive from input 12
 # Lock output 5
   videohubctrl --host sdi \\
                --vi-name 11 "Test input" \\
                --vi-name 12 "Playout input" \\
                --vo-name 5 "Encoder h264" \\
                --vo-route 5 12 \\
                --vo-lock 5
