videohubctrl - Blackmagic Videohub control application
======================================================
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 and
probably works with other Videohub models.
videohubctrl currently displays and can configure:
- Video input port names
- Video output port names, routing and locking
- Input/Output port statuses
- Monitoring video output port names, routing and locking
- Serial ports names, routing, locking and directions
- Processing units
- Frames
- Alarms status
Configuration of Videohub's network settings can be made using
Blackmagic's Windows program when the device is connected via USB.
Configuration of processing units and frames is probably not working
properly because the support was added by just following the very
minimal documentation and with no testing on a real device, so don't
expect miracles in this department. The other stuff is solid but
please see the TODO section of this document and help.

Environment variables
=====================
The following environment variables are checked and used by the program
if they are set:
VIDEOHUB_HOST
Sets the device host name. It is equivalent to using -h / --host
command line parameter.
VIDEOHUB_PORT
Sets the device port. It is equivalent to using -p / --port command
line parameter.
Example usage
=============
# Rename video output
videohubctrl -h sdi --out-name 8 "Output 8 - test"
videohubctrl -h sdi --out-name "Output 8 - test" "Output 8"
# Rename video input
videohubctrl -h sdi --in-name 4 "Windows 4 HD"
videohubctrl -h sdi --in-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 --out-lock 16
videohubctrl --out-unlock "Output 16"
# Set two outputs to receive from the same input using port names
videohubctrl -h sdi --out-input "Output 8" "Windows 4 HD"
videohubctrl -h sdi --out-input "Output 7" "Windows 4 HD"
# Set one input to go out two outputs and two monitoring ports
videohubctrl -h sdi --in-output "Windows 4 HD" "Output 8" \
--in-output "Windows 4 HD" "Output 7" \
--in-monitor "Windows 4 HD" "Monitor 1" \
--in-monitor "Windows 4 HD" "Monitor 2"
# 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 \
--in-name 11 "Test input" \
--in-name 12 "Playout input" \
--out-name 5 "Encoder h264" \
--out-input 5 12 \
--out-lock 5
# This fails. It tries to use name that is not previously configured.
videohubctrl -h sdi --out-name 1 "Test output" \
--out-name "Test output" "Other name"

Development
===========
The development is done using git. videohubctrl repository is hosted at
https://georgi.unixsol.org/git/gfto/videohubctrl
To clone the repository issue the following commands:
git clone https://georgi.unixsol.org/git/gfto/videohubctrl.git
cd videohubctrl
git submodule init
git submodule update
make
The code is developed and tested under modern Linux. It's also compiled
from time to time under OS X but it's not tested there.
Updating the code
=================
To update cloned videohubctrl, go to the directory where the repository
is cloned and run the following commands:
git fetch origin
git merge origin/master
git submodule update
make clean all
videohubctrl's master branch should always be useful so it is safe to
use it instead of official release. The master branch will always
be better than any released version.
Reporting bugs
==============
If you think you have found bug in videohubctrl, please report it to
the e-mail listed in Contact section (see below) of this README file.
When reporting bugs, run 'videohubctrl' with debugging enabled by adding
several --debug (-d) options on the command line, for example:
videohubctrl -d -d -d --host 192.168.0.1
Please add the full command line that you are using and describe what
you think the 'videohubctrl' does wrong.
Also it is very useful to report what VideoHub device reports by
running:
telnet your_videohub_ip 9990
save the output and attach it to your bug report.
TODO list
=========
Help is very much welcome for these tasks:
- Find out what these undocumented commands do:
END PRELUDE:
ENGINEERING:
- Find out what these device options do:
Debug mode:
Power:
- Test the program with Universal Videohub (statuses, serial ports,
monitoring) and Workgroup Videohub (Frames, Processing).
Releases
