OBS Recorder: triggered by VICON signal

2/03/2023

Software Installation

Required Software

• Python3

  • https://www.python.org/downloads/windows/

• Anaconda

  • https://www.anaconda.com/products/individual

  • Quick Note to see if your Windows is 64-Bit.

    If the "C:\Program Files (32)” folder exists, you’re using 64-Bit Windows.

Create a Conda Environment

• After installing Anaconda, create an environment for the capture software.
  • $ conda env create -f environment.yml
• Activate the environment.
  • $ conda activate obs-record

Use vicon-timestamp.py

How to use

Specify a path and port

path is the directory where the timestamp is saved.

ex) your Arduino board is connected to COM1

python vicon-timestamp.py path-to-the-folder COM1

All options

usage: vicon-timestamp.py [-h] [-v VERBOSE]
                          [-b {9600,14400,19200,28800,31250,38400,57600,115200}]
                          path port

VICON Trigger Timestamp ver 0.1 by Jaerock Kwon, 2023

positional arguments:
  path                  path to the location where the timestamp is saved
  port                  Serial port name. COM{#} or /dev/ttyUSB{#}

optional arguments:
  -h, --help            show this help message and exit
  -v VERBOSE, --verbose VERBOSE
                        increase output verbosity
  -b {9600,14400,19200,28800,31250,38400,57600,115200}, --baudrate {9600,14400,19200,28800,31250,38400,57600,115200}
                        baudrate

Use obs-record.py

• First, make sure your Arduino board is connected and running.
• Second, start OBS and get ready for recording. The hotkey for recording start is F3 and stop is F4.
• The most important thing to do is that the OBS is your focused window so that any keyboard inputs can go to the OBS program.

How to use

Specify port name: Mandatory

ex) your Arduino board is connected to COM1

python obs-record.py COM1

All options

python obs-record.py -h

usage: obs-record.py [-h] [-v VERBOSE]
                     [-b {9600,14400,19200,28800,31250,38400,57600,115200}]
                     port

Arudino program

Compile vicon_trigger.ino and upload it to your Arduino board.

Notes:

• Use PIN 7 for the signal.
• baudrate is 115200.
